Vehicle Security

This vehicle has theft-deterrent features; however, they do not make the vehicle impossible to steal.

Vehicle Alarm System

This vehicle has an anti-theft alarm systemKeys and Locks21

The indicator light, on the instrument panel near the windshield, indicates the status of the system.
Off : Alarm system is disarmed.
On Solid : Vehicle is secured during the delay to arm the system
Fast Flash : Vehicle is unsecured. A door, the hood, or the liftgate is open.
Slow Flash : Alarm system is armed.
Arming the Alarm System

  1. Close the liftgate and the hood. Turn off the vehicle.
  2. Lock the vehicle in one of three ways:
    • Use the remote key.
    • Use the Keyless Access system.
    • With a door open, press the inside Q.
  3. After 30 seconds the alarm system will arm, and the indicator light will begin to slowly flash indicating the alarm system is operating. Pressing Q on the remote key a second time will bypass the 30-second delay and immediately arm the alarm system.
    The vehicle alarm system will not arm if the doors are locked with the key. If the driver door is opened without first unlocking with the remote key, the horn will chirp and the lights will flash to indicate pre-alarm. If the vehicle is not started, or the door is not unlocked by pressing K on the remote key during the 10-second pre-alarm, the alarm will be activated. The alarm will also be activated if a passenger door, the liftgate, or the hood is opened without first disarming the system.
    When the alarm is activated, the turn signals flash and the horn sounds for about 30 seconds. The alarm system will then re-arm to monitor for the next unauthorized event.

Disarming the Alarm System
To disarm the alarm system or turn off the alarm if it has been activated:

  • Press K on the remote key.
  • Unlock the vehicle using the Keyless Access system.
  • Start the vehicle.

To avoid setting off the alarm by accident:

  • Lock the vehicle after all occupants have left the vehicle and all doors are closed.
  • Always unlock a door with the remote key or use the Keyless Access system.

Unlocking the driver door with the key will not disarm the system or turn off the alarm.

How to Detect a Tamper Condition
If K is pressed and the horn chirps and the lights flash three times, the alarm was activated while the alarm system was armed.
If the alarm system has been activated, a message will appear on the Driver Information Center (DIC).

Power Sounder, Inclination Sensor, and Intrusion Sensor
In addition to the standard theft-deterrent system features, this system may also have a power sounder, inclination sensor, and intrusion sensor.
The power sounder provides an audible alarm that is distinct from the vehicle’s horn. It has its own power source and can sound an alarm if the vehicle’s battery is compromised.
The inclination sensor can set off the alarm if it senses the movement of the vehicle, such as when a tire is removed. Make sure the vehicle’s alarm is not armed prior to any jacking.
The intrusion sensor monitors the vehicle interior and can activate the alarm if it senses unauthorized entry into the vehicle’s interior. Do not allow passengers or pets to remain in the vehicle when the intrusion sensor is activated.

Before arming the theft-deterrent system and activating the intrusion sensor:

  • Make sure all doors and windows are completely closed.
  • Secure any loose items such as sunglasses.
  • Make sure there are no obstructions blocking the sensors in the front overhead console.

Cadillac CT4 2023 Head Restraints and Rear Seat

User Guide

2023 Cadillac CT4 Head Restraints and Rear Seats Guidelines

Head Restraints

Front Seats

Warning
With head restraints that are not installed and adjusted properly, there is a greater chance that occupants will suffer a neck/spinal injury in a crash. Do not drive until the head restraints for all occupants are installed and adjusted properly. The vehicle’s front seats have adjustable head restraints in the outboard seating positions

Head Restraints1

Adjust the head restraint so that the top of the restraint is at the same height as the top of the occupant’s head. This position reduces the chance of a neck injury in a crash.

Front Seats

If equipped, the vehicle’s front seats have adjustable head restraints in the outboard seating positions.

Head Restraints2.

The height of the head restraint can be adjusted.
To raise or lower the head restraint, press the button located on the side of the head restraint, and pull up or push the head restraint down and release the button. Pull and push on the head restraint after the button is released to make sure that it is locked in place. The front seat outboard head restraints are not removable

Rear Seats

Second Row Seats

The vehicle’s rear second-row seats have adjustable head restraints in the outboard seating positions.
The height of the head restraint can be adjusted. Pull the head restraint up to raise it. Try to move the head restraint to make sure that it is locked in place.

Head Restraints4

To lower the head restraint, press the button, located on the top of the seatback, and push the head restraint down. Try to move the head restraint after the button is released to make sure that it is locked in place. Rear outboard head restraints are not removable.

Front Seats

Power Seat Adjustment
Warning
You can lose control of the vehicle if you try to adjust the driver’s seat while the vehicle is moving. Adjust the driver seat only when the vehicle is not moving.

Warning
The power seats will work with the ignition off. Children could operate the power seats and be injured. Never leave children alone in the vehicle.

Head Restraints7

Thigh Support Adjustment

Head Restraints and Rear Seats1

  • To adjust a power seat, if equipped:
  • Move the seat forward or rearward by sliding the control forward or rearward.
  • Raise or lower the front part of the seat cushion by moving the front of the control up or down.
  • Raise or lower the entire seat by moving the rear of the control up or down. To adjust the seatback, see Reclining Seatbacks 0 38.

To adjust the lumbar support, see Lumbar Adjustment 0 39. Some vehicles are equipped with a feature that activates a vibration in the driver seat  to help the driver avoid crashes. See Driver Assistance Systems 0 231.

Reclining Seatbacks

Warning
Sitting in a reclined position when the vehicle is in motion can be dangerous. Even when buckled up, the seat belts cannot do their job. The shoulder belt will not be against your body. Instead, it will be in front of you. In a crash, you could go into it, receiving neck or other injuries.
The lap belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear the seat belt properly. Do not have a seatback reclined if the vehicle is moving.

Cadillac CT4 2023 Seat Belts User Guide

2023 Cadillac CT4 Connected Services Guidelines

Seat Belts

This section describes how to use seat belts properly, and some things not to do.

Why Seat Belts WorkSeat Belts3

When riding in a vehicle, you travel as fast as the vehicle does. If the vehicle stops suddenly, you keep going until something stops you. It could be the windshield, the instrument panel, or the seat belts!
When you wear a seat belt, you and the vehicle slow down together. There is more time to stop because you stop over a longer distance and, when worn properly, your strongest bones take the forces from the seat belts. That is why wearing seat belts makes such good sense.

Questions and Answers About Seat Belts

Q: Will I be trapped in the vehicle after a crash if I am wearing a seat belt?
A: You could be — whether you are wearing a seat belt or not. Your chance of being conscious during and after a crash, so you can unbuckle and get out, is much greater if you are belted.

Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems only.
They work with seat belts — not instead of them. Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection.
Also, in nearly all states and in all Canadian provinces, the law requires wearing seat belts.

Buckle To Drive

If equipped, this feature delays the vehicle from shifting out of P (Park) when the driver seat belt is not buckled. The Buckle to Drive feature must be turned ON in the infotainment system to work. To turn the Buckle to Drive feature on or off, select Settings > Vehicle > Buckle to Drive. See Teen Driver 0 163, if equipped.
If the vehicle is on and the brake pedal is pressed with the vehicle in P (Park) but the driver seat belt is not buckled, a message displays in the Driver Information Center (DIC) and the vehicle will be delayed from shifting out of P (Park). Buckle the driver seat belt to clear the message and shift out of P (Park). Shifting from P (Park) will be delayed once for each time the vehicle is started.

For some fleet vehicles, the feature is always ON and cannot be turned OFF in the infotainment system. The vehicle will be delayed from shifting from P (Park) each time the driver attempts to do so while the driver seat belt is not buckled. Turning the vehicle off then on will not change this condition.
On some models, Buckle to Drive may also delay shifting out of P (Park) if a front passenger seat belt is unbuckled. A message displays in the DIC. Buckle the front passenger seat belt to shift out of P (Park).

This feature may delay the vehicle from shifting out of P (Park) if an object, such as a briefcase, handbag, grocery bag, laptop, or another electronic device, is on the front passenger seat. If this happens, remove the object from the seat or buckle the seat belt to shift out of P (Park).
If the driver, or on some vehicles, the present front passenger remains unbuckled, the DIC message will turn off after several seconds and the vehicle can be shifted out of P (Park). See “Seat Belts” and “Child Restraints” in the Index for information about the importance of proper restraint use.
If the driver seat belt or the front passenger seat belt is unbuckled when driving, the seat belt reminder chime and light(s) will come on. See Seat Belt Reminders 0 90. This feature may not function properly if the airbag readiness light is on. See Airbag Readiness Light 98.

How to Wear Seat Belts Properly Follow these rules for everyone’s protection.
Follow these rules for everyone’s protection.

There are additional things to know about seat belts and children, including smaller children and infants. If a child will be riding in the vehicle, see Older Children 0 64 or Infants and Young Children 0 66. Review and follow the rules for children in addition to the following rules.
It is very important for all occupants to buckle up. Statistics show that unbelted people are hurt more often in crashes than those who are wearing seat belts.
There are important things to know about wearing a seat belt properly.

Seat Belts4

  • Sit up straight and always keep your feet on the floor in front of you (if possible).
  • Wear the lap part of the belt low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones and you would be less likely to slide under the lap belt.

If you slid under it, the belt would apply force on your abdomen. This could cause serious or even fatal injuries.

  • Wear the shoulder belt over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. The shoulder belt locks if there is a sudden stop or crash.

Warning
You can be seriously injured, or even killed, by not wearing your seat belt properly.Seat Belts5

Seat Belts6

Never allow the lap or shoulder belt to become loose or twisted.

Seat Belts7

Seat Belts8

Never wear the shoulder belt under both arms or behind your back.Seat Belts8

Always use the correct buckle for your seating positionSeat Belts10

Never route the lap or shoulder belt over an armrest.

 Warning
The seat belt can be pinched if it is routed under plastic trim on the seat, such as trim around the rear seatback folding handle or side airbag. In a crash, pinched seat belts might not provide adequate protection. Never allow seat belts to be routed under plastic trim pieces.

Warning
You can be seriously injured or killed if the shoulder belt is worn behind your back, under your legs, or wrapped around your neck. The shoulder belt can tighten but cannot be loosened if it is locked. The shoulder belt locks when it is pulled all the way out of the retractor. It unlocks when the shoulder belt is allowed to go all the way back into the retractor, but it cannot do this if it is wrapped around you. You may have to cut the seat belt if it is locked and tightened around you.

Lap-Shoulder Belt

All seating positions in the vehicle have a lap-shoulder belt. If you are using a rear seating position with a detachable seat belt and the seat belt is not attached, see Rear Seats 0 42 for instructions on reconnecting the seat belt to the mini-buckle.

Cadillac CT4 2023 Airbag System User Guide

2023 Cadillac CT4 Airbag System Guidelines

Airbag System

The vehicle has the following airbags:

  • A frontal airbag for the driver
  • A frontal airbag for the front outboard passenger
  • A knee airbag for the driver
  • A front center airbag for the driver and front outboard passenger
  • A seat-mounted side impact airbag for the driver
  • A seat-mounted side impact airbag for the front outboard passenger
  • A roof-rail airbag for the driver and for the second and third-row passengers seated directly behind the driver
  • A roof-rail airbag for the front outboard passenger and the second and third-row passengers seated directly behind the front outboard passenger

All vehicle airbags have the word AIRBAG on the trim or on a label near the deployment opening. For frontal airbags, the word AIRBAG is on the center of the steering wheel for the driver and on the instrument panel for the front outboard passenger.
For knee airbags, the word AIRBAG is on the lower part of the instrument panel. For the front center airbag, the word AIRBAG is on the inboard side of the driver seatback.
For seat-mounted side impact airbags, the word AIRBAG is on the side of the seatback or side of the seat closest to the door. For roof-rail airbags, the word AIRBAG is on the ceiling or trim. Airbags are designed to supplement the protection provided by seat belts. Even though today’s airbags are also designed to help reduce the risk of injury from the force of an inflating bag, all airbags must inflate very quickly to do their job.

Here are the most important things to know about the airbag system:

Warning
You can be severely injured or killed in a crash if you are not wearing your seat belt, even with airbags. Airbags are designed to work with seat belts, not replace them. Also, airbags are not designed to inflate in every crash. In some crashes seat belts are the only restraint. See When Should an Airbag Inflate? 0 57.
Wearing your seat belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are “supplemental restraints” to the seat belts. Everyone in the vehicle should wear a seat belt properly, whether or not there is an airbag for that person.

Warning
Because airbags inflate with great force and faster than the blink of an eye, anyone who is up against, or very  to any airbag when it inflates can be seriously injured or killed. Do not sit
unnecessarily close to any airbag, as you would be if sitting on the edge of the seat or leaning forward. Seat belts help keep you in position before and during a crash. Always wear a seat belt, even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle. The seat belts and the front outboard passenger airbags are most effective when you are sitting well back and upright in the seat with both feet on the floor.

Occupants should not lean on or sleep against the front center armrest or console in vehicles with a front center airbag. Occupants should not lean on or sleep against the door or side windows in seating positions with seat-mounted side impact airbags and/or roof-rail airbags.

Warning
Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Always secure children properly in the vehicle. To read how, see Older Children 0 64 or Infants and Young Children 0 66.

There is an airbag readiness light on the instrument cluster, which shows the airbag symbol. The system checks the airbag’s electrical system for malfunctions. The light tells you if there is an electrical problem. See Airbag Readiness Light 0 104.

Where Are the Airbags?GMC Acadia 2023 Airbag System1

Child Restraints

Older ChildrenChild Restraints

Older children who have outgrown booster seats should wear the vehicle’s seat belts. Refer to How to Wear Seat Belts Properly 0 48. The manufacturer instructions that come with the booster seat state the weight and height limitations for that booster.

booster seat with a lap-shoulder belt until the child passes the fit test below:

  • Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat.
  • Buckle the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue. If no, try using the rear seat belt comfort guide, if available. See “Rear Seat Belt Comfort Guides” under Lap-Shoulder Belt 0 50. If a comfort guide is not available, or if the shoulder belt still does not rest on the shoulder, then return to the booster seat.
  • Does the lap belt fit low and snug on the hips, touching the thighs? If yes, continue.
    If no, return to the booster seat.
  • Can proper seat belt fit be maintained for the length of the trip? If yes, continue.

If no, return to the booster seat.

Q: What is the proper way to wear seatbelts?
A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck.
The lap belt should fit snugly below the hips, just touching the top of the thighs.
This applies belt force to the child’s pelvic bones in a crash. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
Also see “Rear Seat Belt Comfort Guides” under Lap-Shoulder Belt 0 50.
According to accident statistics, children are safer when properly restrained in a rear seating position. In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use seat belts properly.

Warning
Never allow more than one child to wear the same seat belt. The seat belt cannot properly spread the impact forces. In a crash, they can be crushed together and seriously injured. A seat belt must be used by only one person at a time.

Child Restraints32

Warning
Never allow a child to wear the seat belt shoulder belt under both arms or behind their back. A child can be seriously injured by not wearing the lap shoulder belt properly. In a crash, the child would not be restrained by the shoulder belt.
The child could move too far forward increasing the chance of head and neck injury. The child might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest.

Child Restraints

Infants and Young Children

Everyone in a vehicle needs protection! This includes infants and all other children.
Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.

Warning
Children can be seriously injured or killed the shoulder belt is worn behind their back, under their legs, or wrapped around their neck. The shoulder belt can tighten but cannot be loosened if it is locked. The shoulder belt locks when it is pulled all the way out of the retractor. It unlocks when the shoulder belt is allowed to go all the way back into the retractor, but it cannot do this if it is wrapped around the child. Never leave children unattended in a vehicle and never allow children to improperly wear, or play with, the seat belts.
Every time infants and young children ride in vehicles, they should have the protection provided by appropriate child restraints. Neither the vehicle’s seat belt system nor its airbag system is designed for them. Children who are not restrained properly can strike other people, or can be thrown out of the vehicle.

Warning
Never hold an infant or a child while riding in a vehicle. Due to crash forces, an infant or a child will become so heavy it is not possible to hold it during a crash.
For example, in a crash at only 40 km/h (25 mph), a 5.5 kg (12 lb) infant will suddenly become a 110 kg (240 lb) force on a person’s arms. An infant or child should be secured in an appropriate child restraint.
Child Restraints

Warning
Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Never put a rear-facing child restraint in the front passenger seat. Secure a rear-facing child restraint in a rear seat. It is also better to secure a forward-facing child restraint in a rear seat. If a forward-facing child restraint must be secured in the front passenger seat, always move the front passenger seat as far back as it will go.
Child Restraints5If a child restraint is installed in the second-row center seat, move the second row seat to the rearward position, whenever possible, to minimize contact with the front center airbag. Child restraints are devices used to restrain, seat, or position children in the vehicle and are sometimes called child seats or car seats.
There are three basic types of child restraints:

  • Forward-facing child restraints
  • Rear-facing child restraints
  • Belt-positioning booster seats

The proper child restraint for your child depends on their size, weight, and age, and also on whether the child restraint is compatible with the vehicle in which it will be used.
For each type of child restraint, there are  many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle and is designed by a genuine child restraint manufacturer. If it is, the child restraint will have a label saying that it meets federal motor vehicle safety standards.
The instruction manual that is provided with the child restraint states the weight and height limitations for that particular child restraint. In addition, there are many kinds of child restraints available for children with special needs.

Warning
To reduce the risk of neck and head injury in a crash, infants and toddlers should be secured in a rear-facing child restraint until age two, or until they reach the maximum height and weight limits of their child restraint.

Warning
A young child’s hip bones are still so small that the vehicle seat belt may not remain low on the hip bones, as it should. Instead, it may settle up around
the child’s abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries.
To reduce the risk of serious or fatal injuries during a crash, young children should always be secured in an appropriate child restraint.

The system only activates the high beams when driving over 40 km/h (25 mph).
The blue high-beam on light appears on the instrument cluster when the high beams are on.
There is a sensor near the top center of the windshield that automatically controls the system. Keep this area of the windshield clear of debris to allow for best system performance.
The high-beam headlamps remain on, under automatic control, until one of the following situations occurs:

  • The system detects an approaching vehicle’s headlamps.
  • The system detects a preceding vehicle’s taillamps.
  • The outside light is bright enough that high-beam headlamps are not required.
  • The vehicle’s speed drops below 20 km/h (12 mph).
  • The IntelliBeam system is disabled by the button on the turn signal lever. If this happens, press the button on the end of the turn signal lever when the exterior lamp control is in the AUTO or 2 positions. The instrument cluster light will come on to indicate the IntelliBeam
    the system is reactivated.

The high beams may not turn off automatically if the system cannot detect another vehicle’s lamps because of any of the following:

  • The other vehicle’s lamps are missing, damaged, obstructed from view, or otherwise undetected.
  • The other vehicle’s lamps are covered with dirt, snow, and/or road spray.
  • The other vehicle’s lamps cannot be detected due to dense exhaust, smoke, fog, snow, road spray, mist, or other airborne obstructions.
  • The vehicle’s windshield is dirty, cracked, or obstructed by something that blocks the view of the light sensor.
  • The vehicle is loaded such that the front end points upward, causing the light sensor to aim high and not detect headlamps and taillamps.
  • The vehicle is being driven on winding or hilly roads.

The automatic high-beam headlamps may need to be disabled if any of the above conditions exist.

Daytime Running Lamps (DRL)

DRL can make it easier for others to see the front of your vehicle during the day. Fully functional DRL are required on all vehicles first sold in Canada.

The dedicated DRL will come on when all of the following conditions are met:

  • The ignition is on.
  • The exterior lamp control is in AUTO.
  • The light sensor determines it is daytime.

The taillamps, side marker lamps, instrument panel lights, and other lamps will not be on. When it begins to get dark, the automatic headlamp system switches from DRL to the headlamps. To turn off the DRL, turn the exterior lamp control to O and then release it. For vehicles sold in Canada, this control only works when the vehicle is parked.

Automatic Headlamp System

When the exterior lamp control is set to AUTO and it is dark enough outside, the headlamps come on automatically.

Exterior Lighting4There is a light sensor on top of the instrument panel. Do not cover the sensor. The system may also turn on the headlamps when driving through a parking garage or tunnel.
If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. If it is light outside when the vehicle leaves the garage, there is a slight delay before the automatic headlamp system changes to the Daytime Running Lamps (DRL). During that delay, the instrument cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Illumination Control 0 132. When it is bright enough outside, the headlamps will turn off or may change to DRL. The automatic headlamp system turns off when the exterior lamp control is turned to O or the ignition is off.

Lights On with Wipers
If the windshield wipers are activated in daylight with the engine on, and the exterior lamp control is in AUTO, the headlamps, parking lamps, and other exterior lamps come on. The transition time for the lamps coming on varies based on wiper speed. When the wipers are not operating, these lamps turn off. Move the exterior lamp control to O or ;to disable this feature.

Hazard Warning Flashers

Exterior Lighting5

Press this button to make the front and rear turn signal lamps flash on and off.
This warns others that you are having trouble. Press again to turn the flashers off.
The turn signals do not work while the hazard warning flashers are on.
The hazard warning flashers turn on automatically if the airbags deploy.

Turn and Lane-Change SignalsExterior Lighting6

Move the lever all the way up or down to signal a turn.
An arrow on the instrument cluster will flash in the direction of the turn or lane change. Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it there until the lane change is completed. If the lever is briefly pressed and released, the turn signal flashes three times. The turn and lane-change signal can be turned off manually by moving the lever back to its original position. If after signaling a turn or lane change, the arrow flashes rapidly or does not come on, a signal function may be inoperative. This vehicle may be equipped with LED lighting. For replacement of any LED lighting, contact your dealer.

Cornering Lamps

If equipped with cornering lamps, they automatically come on when all of the following occur:

  • The low-beam headlamps are on.
  • The turn signals are activated or the steering wheel is at a turning angle.
  • The vehicle speed is below 40 km/h (25 mph).

This feature can be changed. On the infotainment home screen, select the Settings icon T Vehicle T Exit Lighting.

Battery Load Management

The vehicle has Electric Power Management (EPM), which estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and extended life of the battery.
When the battery’s state of charge is low, the voltage is raised slightly to quickly bring the charge back up.

When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gauge or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed.

The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads.

A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, and loads plugged into accessory power outlets.

EPM works to prevent excessive discharge of the battery. It does this by balancing the generator’s output and the vehicle’s electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories.

Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a DIC message might be displayed. If a battery message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See Driver Information Center (DIC) (Base Level) 0 102 or Driver Information Center (DIC) (Up level) 0 104.

Battery Power Protection

This feature helps prevent the battery from being drained if the interior courtesy lamps or reading lamps are accidentally left on. If any of these lamps are left on, they automatically turn off after 10 minutes,  if the ignition is off. The lamps will not come back on again until one of the following occurs:

  • The ignition is turned on.
  • The doors are closed and then re-opened.

Exterior Lighting Battery Saver

The exterior lamps turn off about 10 minutes after the vehicle is turned off, if the parking lamps or headlamps have been manually left on. This protects against draining the battery. To restart the 10-minute timer, turn the exterior lamp control to the O position and then back to the ; or 2 position.
To keep the lamps on for more than 10 minutes, the vehicle must be on or in accessory mode.

Cadillac CT4 2023 Voice Recognition and Phone User Guide

2023 Cadillac CT4 Recognition and Phone Instructions

Voice Recognition

If equipped, voice recognition allows for hands-free operation within the navigation, audio, phone, and weather applications. This feature can be started by pressing g on the steering wheel or touching g on the infotainment display. However, not all features within these areas are supported by voice commands. Generally, only complex tasks that require multiple manual interactions to complete are supported by voice commands.

For example, tasks that take more than one or two touches, such as a song or artist to play from a media device, would be supported by voice commands. Other tasks, like adjusting the volume or seeking up or down, are audio features that are easily performed by touching one or two options and are not supported by voice commands. In general, there are flexible ways to speak commands for completing tasks.

If your language supports it, try stating a one-shot command, such as Directions to address <number, street, city, state/province>.” Do not include the ZIP code while stating the address during the command. Another example of a one-shot Destination Entry command s, is Directions to Place of Interest at <hotel>.” If these commands do not work, try saying,  Take me to a Place of Interest or â Find address and the system will walk you through by asking additional questions.

Hybrid Speech Recognition

If equipped, this feature helps distinguish words by using Internet-based information along with the system’s voice recognition database. This allows you to speak more naturally when using voice recognition.

Using Voice Recognition

Voice recognition becomes available once the system has been initialized. This begins when the ignition is turned on. Initialization may take a few moments.

  1.  Press g on the steering wheel controls to activate voice recognition.
  2. The audio system mutes and the system plays a prompt.
  3.  Clearly speak one of the commands described in this section.

A voice recognition system prompt can be interrupted while it is playing by pressing g again. Once voice recognition is started, both the infotainment display and instrument cluster show the selections and visual dialog content. These displays can be turned on or off in the Tutorial Mode under Settings 0 170.

There are three voice prompt modes supported:

  • Informative verbal prompts: This type of prompt will provide more information regarding the supported actions.
  • Short prompts: This type of prompt will provide simple instructions about what can be stated.
  • Auto informative prompts: This type of prompt plays during the first few speech sessions, then automatically switches to the short prompt after some experience has been gained through using the system.

If a command is not spoken, the voice recognition system says a help promptly.

Prompts and Infotainment Displays
While a voice recognition session is active, there may be corresponding options showing on the displays. A selection can be made by manually touching the option, or by speaking the number for the option to select. Manual interaction in the voice recognition session is permitted. Interaction during a voice session may be completed entirely using voice commands while some manual commands may expedite a task. If a selection is made using a manual control, the voice recognition dialog will progress in the same way as if the selection were made using a voice command. Once the system completes the task, or the session is terminated, the voice recognition dialog stops.
An example of this type of manual intervention is touching an entry of a displayed number list instead of speaking the number associated with the entry desired.

Canceling Voice Recognition

  • Touch or say “Cancel” or “Exit” to terminate the voice recognition session and show the display where voice recognition was initiated.
  • Press on the steering wheel controls to terminate the voice recognition session and show the display where voice recognition was initiated.

Natural Language Commands
Most languages do not support natural language commands in sentence form. For those languages, use direct commands like the examples shown on the display.

Helpful Hints for Speaking Commands

Voice recognition can understand commands that are naturally stated in sentence form or direct commands that state the application and the task. For best results:

  • Listen for the prompt before saying a command or reply.
  • Speak the command naturally, not too fast, not too slow.
  • Use direct commands without a lot of extra words. For example, “Call <name> at work,” “Play” followed by the artist or song name, or “Tune” followed by the radio station number.
  • Navigation destinations can be made in a single command using keywords. A few examples are: “I want directions to an address,” “I need to find a place of interest or (POI),” or “Find contact.”
  • The system responds by requesting more details. For other POIs, say the name of a category like “Restaurants,” “Shopping Malls,” or “Hospitals.”
  • Navigating to a destination outside of the current country takes more than one command. The first command is to tell the system where the navigation will take places, such as an Address, Intersection, POI, or Contact. If Address or Intersection is selected, the second command is to say, “Change Country.” Once the system responds, say the country before saying the rest of the address and/or intersection.

If POI is asked for, say “Change Location,” then “Change Country.”
Direct commands might be more clearly understood by the system. An example of a direct command would be “Call <number>.” Examples of these direct commands are displayed on most of the screens while a voice session is active. If “Phone” or “Phone Commands,” is spoken, the system understands that a phone call is requested and will respond with questions until enough details are gathered to make a call. If a cell phone number has been saved with a name and a place, the direct command should include both, for example “Call <name> at work.”

Using Voice Recognition for List Options

When a list is displayed, a voice prompt will ask to confirm or select an option from that list.
When a display contains a list, there may be options that are available but not displayed. The list on a voice recognition screen functions the same as a list on other displays. Scrolling or flinging can be used to help display other entries from the list. Manually scrolling or paging the list on a display during a voice recognition session suspends the current voice recognition event and plays the prompt “Please select manually or touch the Back icon on the infotainment display to try again.”
If manual selection takes more than 15 seconds, the session terminates and prompts that it has timed out. The display returns to the display where voice recognition was initiated The Back Command Say “Back” or touch the Back icon on the infotainment display to go to the previous menu.
If in voice recognition, and “Back” is spoken all the way back to the starting display, and then “Back” is spoken one more time, the voice recognition session will cancel.

Help
Say “Help” on any voice recognition display and the help prompt for the display is played.

Voice Recognition for the Radio
If browsing the audio sources when voice is touched, the voice recognition commands for AM, FM, and SiriusXM (if equipped) are available.

“Switch to AM”: Switch bands to AM and tune to the last AM radio station.

“Switch to FM”: Switch bands to FM and tune to the last FM radio station.

“Switch to SXM”: Switch bands to SiriusXM and tune to the last SiriusXM channel.

“Tune to <AM frequency> AM”: Tune to the radio station whose frequency is identified in the command (like “nine fifty”).
“Tune to <FM frequency> FM” : Tune to the radio station whose frequency is identified in the command (like “one oh one point one”).

“Tune to <AM frequency> AM HD” : Tune
to the HD Radio station (if equipped) whose frequency is identified in the command.
“Tune to <FM frequency> FM HD” : Tune to the HD Radio station (if equipped) whose frequency is identified in the command.

“Tune to <FM frequency> FM HD <HD
channel number>” : Tune to the HD Radio station (if equipped) whose frequency and HD channel are identified in the command.

“Tune to SXM <SXM channel number>” :
Tune to the SiriusXM radio station whose channel number is identified in the command.
“Tune to SXM <SXM channel name>” : Tune to the SiriusXM radio station whose channel name is identified in the command.

Climate Control Status Display

The climate control status display appears briefly when the center stack climate controls are adjusted.

Climate Control Influence on Fuel Economy

The climate control system depends on other vehicle systems for heat and power input. Certain climate control settings can lead to higher fuel usage.

The following climate control settings use more fuel:

  • MAX air conditioning mode
  • Defrost mode
  • Extreme temperature settings, such as 15° C (60° F) or 32° C (90° F)
  • High fan speed settings

To help reduce fuel usage:

  • Use the full automatic control as described under “Automatic Operation.”
  • Select a temperature setting that is higher in hot weather and lower in cold weather.
  • Turn off the air conditioning when it is not needed.
  • Only use defrost to clear the windows.

Automatic Operation
The system automatically controls the following four functions to heat or cool the vehicle to the desired temperature:

  • Fan Speed
  • Air Delivery Mode
  • Air Conditioning
  • Recirculation

When the AUTO indicator light is lit, all four functions are operating automatically. Each function can be manually set and the selected setting will be shown. This cancels full automatic operation and the AUTO indicator light turns off. Functions that are not manually set will continue to be automatically controlled, although the AUTO indicator light will not be lit.

To place the system in automatic mode:

  1. Press AUTO.
  2. Set the driver and passenger temperature.

To find your comfort setting, start with 22 °C (72 °F) and allow the system time to stabilize. Then adjust the temperature as needed for best comfort
To improve fuel efficiency and to cool the vehicle faster, recirculation may be automatically selected in warm weather. The recirculation light will not come on when automatically controlled. Press @ to manually select recirculation; press it again to select outside air. Do not cover the solar sensor on the top of the instrument panel near the windshield. This sensor regulates air temperature based on sun load. See “Sensors” later in this section.

Driving Information

Driving for Better Fuel Economy

Driving habits can affect fuel mileage. Here are some driving tips to get the best fuel economy possible.

  • Set the climate controls to the desired temperature after the engine is started or turn them off when not required.
  • On AWD vehicles, see Driver Mode Control 0 220.
  • Avoid fast starts and accelerate smoothly.
  • Brake gradually and avoid abrupt stops.
  • Avoid idling the engine for long periods of time.
  • When road and weather conditions are appropriate, use cruise control.
  • Always follow posted speed limits or drive more slowly when conditions require.
  • Keep vehicle tires properly inflated.
  • Combine several trips into a single trip.
  • Replace the vehicle’s tires with the same TPC Spec number molded into the tire’s sidewall near the size.
  • Follow recommended scheduled maintenance.

Distracted Driving

Distraction comes in many forms and can take your focus from the task of driving. Exercise good judgment and do not let other activities divert your attention away from the road. Many local governments have enacted laws regarding driver distraction. Become familiar with the local laws in your area.
To avoid distracted driving, keep your eyes on the road, keep your hands on the steering wheel, and focus your attention on driving.

  • Do not use a phone in demanding driving situations. Use a hands-free method to place or receive necessary phone calls.
  • Watch the road. Do not read, take notes, or look up information on phones or other electronic devices.
  • Designate a front-seat passenger to handle potential distractions.
  • Become familiar with vehicle features before driving, such as programming favorite radio stations and adjusting climate control and seat settings. Program all trip information into any navigation device prior to driving.
  • Wait until the vehicle is parked to retrieve items that have fallen to the floor.
  • Stop or park the vehicle to tend to children.
  • Keep pets in an appropriate carrier or restraint.
  • Avoid stressful conversations while driving, whether with a passenger or on a cell phone.

Warning
Taking your eyes off the road too long or too often could cause a crash resulting in injury or death. Focus your attention on driving. Refer to the infotainment section for more information on using that system and the navigation system, if equipped, including pairing and using a cell phone.

Defensive Driving

Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear a seat belt. See Seat Belts 0 47.

  • Assume that other road users (pedestrians, bicyclists, and other drivers) re going to be careless and make mistakes. Anticipate what they may do and be ready.
  • Allow enough following distance between you and the driver in front of you.
  • Focus on the task of driving.

Impaired Driving

Death and injury associated with impaired driving is a global tragedy.

Warning
Drinking alcohol or taking drugs and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol or drugs. You can have a serious — or even fatal — collision if you drive after drinking or taking drugs.
Do not drive while under the influence of alcohol or drugs, or ride with a driver who has been drinking or is impaired by drugs. Find alternate transportation home; or if you are with a group, designate a driver who will remain sober.

Control of a Vehicle

Braking, steering, and accelerating are important factors in helping to control a vehicle while driving.

Braking
Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time. The average driver reaction time is about three-quarters of a second. In that time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which could be a lot of distance in an emergency.

Helpful braking tips to keep in mind include:

  • Keep enough distance between you and the vehicle in front of you.
  • Avoid needless heavy braking.
  • Keep pace with traffic.

If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. Doing so could make the pedal harder to push down. If the engine stops, there will be some power brake assist but it will be used when the brake is applied. Once the power assist is used up, it can take longer to stop and the brake pedal will be harder to push.

Steering

Caution
To avoid damage to the steering system, do not drive over curbs, parking barriers, or similar objects at speeds greater than 3 km/h (1 mph). Use care when driving over other objects such as lane dividers and speed bumps. Damage caused by misuse of the vehicle is not covered by the vehicle warranty.

Driving Information

Electric Power Steering

The vehicle is equipped with an electric power steering system, which reduces the amount of effort needed to steer the vehicle. It does not have a power steering fluid. Regular maintenance is not required. If the vehicle experiences a system malfunction and loses power steering, greater steering effort may be required.
Power steering assist also may be reduced if you turn the steering wheel as far as it can turn and hold it there with force for an extended period of time.
See your dealer if there is a problem.

Curve Tips

  • Take curves at a reasonable speed.
  • Reduce speed before entering a curve.
  • Maintain a reasonable steady speed through the curve.
  • Wait until the vehicle is out of the curve before accelerating gently into the straightaway.

Steering in Emergencies

  • There are some situations when steering around a problem may be more effective than braking.
  • Holding both sides of the steering wheel allows you to turn 180 degrees without removing a hand.
  • The Antilock Brake System (ABS) allows steering while braking

Cadillac CT4 2023 Starting and Operating User Guide

2023 Cadillac CT4 Starting and Operating Guidelines

Starting and Operating

New Vehicle Break-In

Caution
Follow these recommended guidelines during the first 2 414 km (1,500 mi) of driving this vehicle. Parts have a break-in period and performance will be better in the long run.

  • Avoid full throttle starts and abrupt stops.
  • Do not exceed 4000 engine rpm.
  • Avoid driving at any one constant speed, fast or slow.
  • Do not drive above 129 km/h (80 mph).
  • Avoid downshifting to brake or slow the vehicle when the engine speed will exceed 4000 rpm.
  • Do not let the engine labor. Never lug the engine in high gear at low speeds. With a manual transmission, shift to the next lower gear. This rule applies
    at all times, not just during the break-in period.
  • Check engine oil with every refueling and add if necessary. Oil and fuel consumption may be higher than normal during the first 2 414 km (1,500 mi).
  • To break in new tires, drive at moderate speeds and avoid hard cornering for the first 322 km (200 mi).
    New tires do not have maximum traction and may tend to slip.
  • New brake linings also need a break-in period. Avoid making hard stops during the first 322 km (200 mi). This is recommended every time brake linings are replaced.
  • Should the vehicle be used for racing or competitive driving (after the break-in), the rear axle lubricant must be replaced beforehand.

See Track Events and Competitive Driving (V-Series and V-Series Blackwing) 0 183

On new vehicles, the various mechanical and electrical systems experience a “break-in” period during the first 6,400 km (4,000 miles) of routine driving. As the vehicle is driven, the mechanical systems adjust to provide optimal fuel economy and transmission shift performance.
Electrical systems will adapt and calibrate during the break-in period. A one-time occurrence of clicks and similar vehicle noises is normal during this process.
Normal driving charges the vehicle’s battery to achieve the best operation of the vehicle, including fuel economy.

Composite Materials

This vehicle may be equipped with parts containing carbon fiber, sheet-molding compound, or other composite materials.
Dealer-installed accessories may also contain composite materials.

Warning
Exposed edges of parts containing carbon fiber and other composite materials can be sharp. Contact with these parts could result in injury. Use caution to avoid contacting these parts, including when washing the vehicle. If the parts are damaged, replace the parts promptly with replacements from your dealer.

Warning
Rocker extensions may break under pressure, resulting in property damage or injury. Do not stand on the rocker extension or use it as a step.

Warning
Rear-end spoilers may break under pressure, resulting in property damage or injury. Do not push the vehicle by the spoiler or use the spoiler as a handle.

Ignition PositionsStarting and Operating

The vehicle has an electronic keyless ignition with a pushbutton start.
The remote key must be in the vehicle for the system to operate. If the pushbutton start is not working, the vehicle may be near a strong radio antenna signal causing interference to the remote key system. See Remote Key Operation 0 7.

To shift out of P (Park), the vehicle must be on and the brake pedal must be applied. Stopping the Engine/LOCK/OFF (No Indicator Lights) : When the vehicle is stopped, press ENGINE START/STOP once to turn the engine off. If the vehicle is in P (Park), the ignition will turn off, and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) 0 205.

The vehicle may have an electric steering column lock. The lock is activated when the vehicle is switched to OFF and the driver door is opened. A sound may be heard as the lock actuates or releases. The steering column lock may not release with the wheels turned off center. If this happens, the vehicle may not start. Move the steering wheel from left to right while attempting to start the vehicle. If this does not work, the vehicle needs service. Do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags.

If the vehicle must be shut off in an emergency:

  1. Brake using firm and steady pressure. Do not pump the brakes This may deplete power assist, requiring increased brake pedal force.
  2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving. After shifting to N (Neutral), firmly apply the brakes and steer the vehicle to a safe location.
  3. Come to a complete stop and shift to P (Park).
  4. Set the parking brake. See Electric Parking Brake 0 216. And press ENGINE START/STOP to turn the vehicle off.

Warning
Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency. If the vehicle cannot be pulled over, and must be shut off while driving, press and hold ENGINE START/STOP for longer than two seconds, or press twice in five seconds.

Accessory Mode (Amber Indicator Light): This mode allows some electrical accessories to be used when the engine is off.
With the ignition off, pressing the button one time without the brake pedal applied will place the ignition system in accessory mode.
The ignition will switch from accessory mode to off after five minutes to prevent battery rundown.

ON/RUN/START (Green Indicator Light): This mode is for driving and starting. With the ignition off, and the brake pedal applied, pressing the button once will place the ignition system in ON/RUN/START. Once engine cranking begins, release the button. Engine cranking will continue until the engine starts. See Starting the Engine 0 205. The ignition will then remain in ON/RUN.

Service Mode

This power mode is available for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. With the vehicle off, and the brake pedal not applied, pressing and holding the button for more than five seconds will place the vehicle in Service Mode. The instruments and audio systems will operate as they do in ON/RUN, but the vehicle will not be able to be driven. The engine will not start in Service Mode. Press the button again to turn the vehicle off.

Starting the Engine

Place the transmission in the proper gear.

Caution
If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment 0 283.

Automatic Transmission

Cadillac CT4 2023 Ride Control Systems and Cruise Control Guide

2023 Cadillac CT4 Ride and Cruise Control Guidelines

Ride Control Systems

Traction Control/Electronic Stability Control System Operation

The vehicle has a Traction Control System (TCS) and StabiliTrak/Electronic Stability Control (ESC), an electronic stability control system. These systems help limit wheel spin and assist the driver in maintaining control, especially on slippery road conditions.

TCS activates if it senses that any of the drive wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin. StabiliTrak/ESC activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak/ESC selectively applies braking pressure to any one of the vehicle wheel brakes to assist the driver in keeping the vehicle on the intended path.

If cruise control is being used and TCS or StabiliTrak/ESC begins to limit wheel spin, cruise control will disengage. Cruise control may be turned back on when road conditions allow. TCS and StabiliTrak/ESC will automatically turn on when cruise control is set.
Both systems come on automatically when the vehicle is started and begins to move. The systems may be heard or felt while they are operating or while performing diagnostic checks. This is normal and does not mean there is a problem with the vehicle. It is recommended to leave both systems on for normal driving conditions, but it may be necessary to turn TCS off if the vehicle gets stuck in sand, mud, ice, or snow. See If the Vehicle Is Stuck 0 200 and “Turning the Systems Off and On” later in this section.

The indicator light for both systems is in the instrument cluster. This light will.

  • Will flash when TCS is limiting wheel spin
  • Will flash when StabiliTrak/ESC is activated
  • Will turn on and stay on when either system is not working
  • May flash when ABS is active

If either system fails to turn on or to activate, a message may display in the Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly.

If d comes on and stays on:

  1. Stop the vehicles.
  2. Turn the engine off and wait for 15
  3. Start the engine.
  4. Drive the vehicle.
    If d comes on and stays on, the vehicle may need more time to diagnose the problem. If the condition persists, see your dealer.

Turning the Systems Off and OnRide Control Systems1

Caution
Do not repeatedly brake or accelerate heavily when TCS is off. The vehicle driveline could be damaged.
To turn off only TCS, press and release g. The Traction Off light i displays in the instrument cluster and a DIC message may display.
To turn TCS on again, press and release g. The Traction Off light i displayed in the instrument cluster will turn off.
If TCS is limiting wheel spin when g is pressed, the system will not turn off until the wheels stop spinning.
To turn off both TCS and StabiliTrak/ESC, press and hold g until the Traction Off light i and StabiliTrak/ESC OFF light g come on and stay on in the instrument cluster. A DIC message may display.
To turn TCS and StabiliTrak/ESC on again, press and release g. The Traction Off light i and StabiliTrak/ESC OFF light g in the instrument cluster turn off.
StabiliTrak will automatically turn on if the vehicle exceeds 56 km/h (35 mph). Traction control will remain off.

Cadillac CT4 2023 Fuel and Conversions and Add-Ons User Guide

2023 Cadillac CT4 Conversions and Add-Ons Guidelines

Fuel

Top Tier Fuel

GM recommends the use of TOP TIER Detergent Gasoline to keep the engine clean, reduce engine deposits, and maintain optimal vehicle performance. Look for the TOP TIER Logo or see www.toptiergas.com for a list of TOP TIER Detergent Gasoline marketers and applicable countries

GMC Acadia 2023 Fuel2

Recommended Fuel

Fuel and Conversions and Add-Ons1

Regular unleaded gasoline meeting ASTM specification D4814 with a posted octane rating (R+M)/2 of 87 or greater is recommended. Do not use gasoline with a posted octane rating of less than 87, as this will result in reduced performance and driveability. If heavy knocking is heard when using gasoline rated at 87 or greater, the engine needs service. Do not use any fuel labeled E85 or FlexFuel. Do not use gasoline with ethanol levels greater than 15% by volume.

Prohibited Fuels

Caution
Do not use fuels with any of the following conditions; doing so may damage the vehicle and void its warranty:

  • For vehicles that are not FlexFuel, fuel labeled greater than 15% ethanol by volume, such as mid-level ethanol blends (16–50% ethanol), E85, or FlexFuel.
  •  Fuel with any amount of methanol, methylal, ferrocene, and aniline. These fuels can corrode metal fuel system parts or damage plastic and rubber parts.
  • Fuel containing metals such as methylcyclopentadienyl manganese tricarbonyl (MMT), which can damage the emissions control system and spark plugs.
  • Fuel with a posted octane rating of less than the recommended fuel. Using this fuel will lower fuel economy and performance, and may decrease the life of the emissions catalyst.

Fuels in Foreign Countries

The U.S., Canada, and Mexico post fuel octane ratings in anti-knock index (AKI). For fuel not to use in a foreign country, see Prohibited Fuels 0 275.

Fuel Additives

TOP TIER Detergent Gasoline is highly recommended for use with your vehicle.
If your country does not have TOP TIER Detergent Gasoline, add ACDelco Fuel System Treatment Plus−Gasoline to the vehicle’s gasoline fuel tank at every oil
change or 15 000 km (9,000 mi), whichever occurs first. TOP TIER Detergent Gasoline and ACDelco Fuel System Treatment Plus  Gasoline will help keep your vehicle’s engine fuel deposit free and performing optimally.

Filling the Tank

An arrow on the fuel gauge indicates which side of the vehicle the fuel door is on. See Fuel Gauge 89.

Cadillac CT4 2023 Headlamp Aiming and Electrical System User Guide

2023 Cadillac CT4 Headlamp Aiming and Electrical System Guidelines

Headlamp Aiming

Front Headlamp Aiming

The headlamp aim has been preset and should need no further adjustment. If the vehicle is damaged in a crash, the headlamp aim may be affected. If adjustment to the headlamps is necessary, see your dealer.

Bulb Replacement

For the proper type of replacement bulbs, or any bulb changing procedure not listed in this section, contact your dealer.

Caution
Do not replace incandescent bulbs with aftermarket LED replacement bulbs. This can cause damage to the vehicle electrical system.

Halogen Bulbs

Warning
Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured. Be sure to read and follow the instructions on the bulb package.

High-Intensity Discharge (HID) Lighting

Warning
The High Intensity Discharge (HID) lighting system operates at a very high voltage. If you try to service any of the system components, you could be seriously injured. Have your dealer or a qualified technician service them.
After an HID headlamp bulb has been replaced, the beam might be a slightly different shade than it was originally. This is normal.

LED Lighting

This vehicle has several LED lamps. For replacement of any LED lighting assembly, contact your dealer.

Front Turn Signal Lamps Uplevel

See your dealer for turn signal replacement.

Base level
To replace one of these lamps:

  1.  Open the hood.
  2. If your vehicle is equipped with a beauty cover, remove the beauty cover to get access to the bulb.
    Headlamp Aiming and Electrical System
  3.  Turn the bulb socket counterclockwise to remove it from the headlamp assembly.
  4. Unplug the electrical connector from the bulb by releasing the clip on the connector.
  5. Replace the bulb and reverse Steps 1–4 to reinstall.

Electrical System

Electrical System Overload
The vehicle has fuses and circuit breakers to protect against an electrical system overload.
When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed.

This greatly reduces the chance of circuit overload and fire caused by electrical problems. Fuses and circuit breakers protect power devices in the vehicle.
If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. Choose some feature of the vehicle that is not needed to use and replace it as soon as possible.
To check a fuse, look at the band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a fuse of identical size and rating.Headlamp Aiming and Electrical System1

Headlamp Aiming1

Replacing a Blown Fuse

  1. Turn off the vehicle.
  2.  Locate the fuse puller in the engine compartment fuse block.
  3. Use the fuse puller to remove the fuse from the top or side, as shown above.
    Headlamp Aiming12Headlamp Aiming13
  4.  If the fuse must be replaced immediately, borrow a replacement fuse with the same amperage from the fuse block. Choose a vehicle feature that is not needed to safely operate the vehicle. Repeat Steps 2-3.
  5. Insert the replacement fuse into the empty slot of the blown fuse.

At the next opportunity, see your dealer to replace the blown fuse.

Headlamp Wiring

An electrical overload may cause the lamps o go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off.

 Windshield Wipers

If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart.
Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.

Fuses and Circuit Breakers

The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems.

Danger
Fuses and circuit breakers are marked with their ampere rating. Do not exceed the specified amperage rating when replacing fuses and circuit breakers. Use of an oversized fuse or circuit breaker can result in a vehicle fire. You and others could be seriously injured or killed.

Warning
Installation or use of fuses that do not meet GM’s original fuse specifications is dangerous. The fuses could fail, and result in a fire. You or others could be injured or killed, and the vehicle could be damaged. See Accessories and Modifications 0 262 and General Information 0 262. To check or replace a blown fuse, see Electrical System Overload 0 283.

Engine Compartment Fuse Block

The underhood fuse block is in the engine compartment, on the driver side of the vehicle.Headlamp Aiming14

Cadillac CT4 2023 Wheels and Tires User Guide

2023 Cadillac CT4 Wheels and Tires Instructions

Wheels and Tires

Every new GM vehicle has high-quality tires made by a leading tire manufacturer. See the warranty manual for information regarding the tire warranty and where to get service. For additional information refer to the tire manufacturer.

Warning

  • Poorly maintained and improperly used tires are dangerous.
  • Overloading the tires can cause overheating as a result of too much flexing. There could be a blowout and a serious crash. See Vehicle Load Limits 0 200.
  • Underinflated tires pose the same danger as overloaded tires. The resulting crash could cause serious injury. Check all tires frequently to maintain the recommended
  • pressure. Tire pressure should be checked when the tires are cold.
  • Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact — such as when hitting a pothole. Keep tires at the recommended pressure.
  • Worn or old tires can cause a crash. If the tread is badly worn, replace them.
  • Replace any tires that have been damaged by impacts with potholes, curbs, etc.
  • Improperly repaired tires can cause a crash. Only your dealer or an authorized tire service center should repair, replace, dismount, and mount the tires.
  • Do not spin the tires in excess of 56 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the tires to explode.

See Tire Pressure for High-Speed Operation 0 300 for inflation pressure adjustment for high-speed driving.

All-Season Tires

This vehicle may come with all-season tires. These tires are designed to provide good overall performance on most road surfaces and weather conditions. Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. Original equipment all-season tires can be identified by the last two characters of this TPC code, which will be “MS.”

Consider installing winter tires on the vehicle if frequent driving on snow or ice-covered roads is expected. All-season tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter tires on snow or ice-covered roads. See Winter Tires 0 322.

Winter Tires

This vehicle was not originally equipped with winter tires. Winter tires are designed for increased traction on snow and ice-covered roads. Consider installing winter tires on the vehicle if frequent driving on ice or snow-covered roads is expected. See your dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires 0 336.

With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After changing to winter tires, be alert for changes in vehicle handling and braking.

If using winter tires:

  • Use tires of the same brand and tread type on all four wheel positions.
  • Use only radial ply tires of the same size, load range, and speed rating as the original equipment tires.

Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y, and ZR speed-rated tires. If winter tires with a lower speed rating are chosen, never exceed the tire’s maximum speed capability.

Run-Flat Tires

This vehicle, when new, may have had run-flat tires. There is no spare tire, no tire changing equipment, and no place to store a tire in the vehicle

Warning
While driving with run-flat tires at a reduced inflation pressure, avoid making sudden stops or severe maneuvers as the handling capabilities of the tires will be reduced. Driving too fast could cause loss of control and you or others could be injured. Do not drive over 80 km/h (50 mph) with the tire operating at low pressure. Drive cautiously and check the tire pressure as soon as possible.

Run-flat tires can be driven up to 80 km (50 mi) at speeds less than 80 km/h (50 mph) after a loss of inflation pressure has occurred. There is no need to stop on the side of the road to change the tire. The possible driving range after a pressure loss will vary based on the vehicle load and driving conditions. As soon as possible, contact the nearest authorized GM or run-flat servicing facility for inspection and repair or replacement.

When driving on a deflated run-flat tire, avoid potholes and other road hazards that could damage the tire and/or wheel beyond repair. When a tire has been damaged, or if driven any distance while deflated, check with an authorized run-flat tire service center to determine whether the tire can be repaired or should be replaced. To maintain the run-flat feature, all replacement tires must be run-flat tires. To locate the nearest GM or run-flat servicing facility, call Customer Assistance.

Self-Sealing Tires

This vehicle may have self-sealing tires. These tires have material inside that can seal punctures from common road hazards, such as nails and screws, in the tread area. The tire may lose air pressure if the sidewall is damaged or the tread puncture is too large. If the Tire Pressure Monitor System indicates the tire pressure is low, inspect the tire for damage and inflate it to the recommended pressure. If the tire is unable to maintain the recommended pressure, contact the nearest authorized GM servicing facility immediately for inspection and repair or replacement. To locate the nearest GM servicing facility, call. GM Customer Assistance.

Caution
Do not drive on a deflated self-sealing tire as this could damage the tire. Make sure the tire is inflated to the recommended pressure or have it immediately repaired or replaced. When tire replacement is needed replace with a self-sealing tire because the vehicle does not come with a spare tire or tire changing equipment.

Low-Profile Tires
If the vehicle has 225/45R17 91V, 235/40R18 91V, 235/40R18 XL 95Y, or 235/35R19 XL 91V, 255/35ZR18 (94Y), or 275/35ZR18 (99Y) size tires, they are classified as low-profile tires.

Caution
Low-profile tires are more susceptible to damage from road hazards or curb impact than standard-profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like potholes, or sharp-edged objects, or when sliding into a curb. The warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and when possible, avoid contact with curbs, potholes, and other road hazards.

Summer Tires

High-Performance Summer Tires
This vehicle may come with 235/40R18 XL 95Y, 255/35ZR18 (94Y), or 275/35ZR18 (99Y) high-performance summer tires. These tires have a special tread and compound that are optimized for maximum dry and wet road performance. This special tread and compound will have decreased performance in cold climates, and on ice and snow. It is recommended that winter tires be installed on the vehicle if frequent driving at temperatures below approximately 5 °C (40 °F) or on ice or snow-covered roads is expected. See Winter Tires 0 322.

Caution
High-performance summer tires have rubber compounds that lose flexibility and may develop surface cracks in the tread area at temperatures below −7 °C (20 °F). Always store high-performance summer tires indoors and at temperatures above −7 °C (20 °F) when not in use. If the tires have been subjected to −7 °C (20 °F) or less, let them warm up in a heated space to at least 5 °C (40 °F) for 24 hours or more before being installed or driving a vehicle on which they are installed. Do not apply heat or blow heated air directly on the tires. Always inspect tires before use. See Tire Inspection 0 334.

Tire Sidewall Labeling

Useful information about a tire is molded into its sidewall. The examples show a typical passenger vehicle tire and a compact spare tire sidewall.Wheels and Tires1

Jumper Cable Removal

Reverse the sequence exactly when removing the jumper cables.
After starting the disabled vehicle and removing the jumper cables, allow it to idle for several minutes.

Towing the Vehicle

Transporting a Disabled Vehicle (Electronic Shifter

Caution
Incorrectly transporting a disabled vehicle may cause damage to the vehicle. Use proper tire straps to secure the vehicle to the flatbed tow truck. Do not strap or hook to any frame, underbody, or suspension component not specified below. Do not move vehicles with drive axle tires on the ground. Damage is not covered by the vehicle warranty.

Caution
The vehicle may be equipped with an electric parking brake and/or an electronic shifter. In the event of a loss of 12-volt battery power, the electric parking brake cannot be released, and the vehicle cannot be shifted to N (Neutral). Tire skates or dollies must be used under the non-rolling tires to prevent damage while loading/unloading the vehicle. Dragging the vehicle will cause damage not covered by the vehicle warranty.

Caution
The vehicle may be equipped with a tow eye. Improper use of the tow eye may cause damage to the vehicle and is not covered by the vehicle warranty.
If equipped, use the tow eye to load the vehicle onto a flatbed tow truck from a flat road surface, or to move the vehicle a very short distance at a walking pace.
The tow eye is not designed for off-road recovery. The vehicle must be in N (Neutral) with the electric parking brake released when using the tow eye.

Contact a professional towing service if the disabled vehicle must be transported. GM recommends a flatbed tow truck to transport a disabled vehicle. Use ramps to help reduce approach angles, if necessary.

If equipped, a tow eye may be located near the spare tire or emergency jack. Do not use the tow eye to pull the vehicle from the snow, mud, sand, or ditch. Tow eye threads may have right or left-hand threads. Use caution when installing or removing the tow eye.

The vehicle must be in N (Neutral) and the electric parking brake must be released when loading the vehicle onto a flatbed tow truck.

  • If the vehicle is equipped with car wash mode and has 12-volt battery power, refer to “Car Wash Mode” under Automatic Transmission 0 211 to place the vehicle in N (Neutral).
  • If the 12-volt battery is dead and/or the engine will not start, the vehicle will not move. Try to jump start the Refer to Jump Starting – North America 0 324 and if the jump start is successful, retry the “Car Wash Mode” procedure.
  • If jump starting is unsuccessful, the vehicle will not move. Tire skates or dollies must be used under the non-rolling tires to prevent vehicle damage.

V-Series Blackwing Only

Jump Starting and Towing the Vehicle2

Due to low ramp angles on the V-Series Blackwing, use care when loading the vehicle onto a flatbed carrier. Front spring spacers were provided for lifting the front suspension if more clearance is necessary when towing.

Front Tow EyeJump Starting and Towing the Vehicle3

The vehicle is equipped with specific attachment points to be used by the towing provider. These holes may be used to pull the vehicle from a flat road surface onto the flatbed tow truck.

Carefully open the cover in the fascia by using the small notch that conceals the tow eye socket.
Install the tow eye into the socket and turn it until it is fully tightened. When the tow  eye is removed, reinstall the cover with the notch in the original position.

Appearance Care

Exterior Care

Locks
Locks are lubricated at the factory. Use a de-icing agent only when absolutely necessary, and have the locks greased after using. See Recommended Fluids and Lubricants 0 343.

Washing the Vehicle

To preserve the vehicle’s finish, wash it often and out of direct sunlight.

Caution
Do not use petroleum-based, acidic, or abrasive cleaning agents as they can damage the vehicle’s paint, metal, or plastic parts. If damage occurs, it  would not be covered by the vehicle warranty. Approved cleaning products can be obtained from your dealer. Follow all manufacturer directions regarding correct product usage, necessary safety precautions, and appropriate disposal of any vehicle care product.

Caution
Avoid using high-pressure washes closer than 30 cm (12 in) to the surface of the vehicle. Use of power washers exceeding 8 274 kPa (1,200 psi) can result in damage or removal of paint and decals.

Automatic Car Wash

Caution
Automatic car washes can cause damage to the vehicle, wheels, ground effects, and convertible top (if equipped).
Do not use automatic car washes due to lack of clearance for the undercarriage, wide rear tires, and wheels.

Caution
To avoid damage to a matte paint finish, do not use an automatic car wash equipped with brushes or scrubbers. Only use touchless automatic car washes.

If using an automatic car wash, follow the car wash instructions. The windshield wiper and rear window wiper, if equipped, must be off. Remove any accessories that may be damaged or interfere with the car wash equipment.

Hand Wash
Rinse the vehicle well, before and after washing, to remove all cleaning agents completely. If they are allowed to dry on the surface, they could stain.
Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting.

Cleaning Under hood Components

Caution
Do not power wash any component under the hood that has this symbol.

This could cause damage that would not be covered by the vehicle warranty. Solvents or aggressive cleaners may harm under-hood components. The usages of these chemicals should be avoided. Recommend water only. A pressure washer may be used, but care must be utilized.

The following criteria must be followed:

  • Water pressure must be kept below 14 000 KPa (2,000 PSI).
  • Water temperature must be below 80 °C (180 °F).
  • Spray nozzle with a 40 degree wide angle spray pattern or wider must be used.
  • Nozzle must be kept at least 30 cm (1 ft) away from all surfaces.

Finish Care
Application of aftermarket clearcoat sealant/ wax materials is not recommended.
If painted surfaces are damaged, see your dealer to have the damage assessed and repaired. Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage the vehicle’s finish if they remain  on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter.
Occasional hand waxing or mild polishing should be done to remove residue from the paint finish. See your dealer for approved cleaning products.
Do not apply waxes or polishes to uncoated plastic, vinyl, rubber, decals, simulated wood, or flat paint as damage can occur.

Caution
Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint finish on the vehicle. To keep the paint finish looking new, keep the vehicle garaged or covered whenever possible

Protecting Exterior Bright Metal Moldings

Caution
Failure to clean and protect the bright metal moldings can result in a hazy white finish or pitting. This damage would not be covered by the vehicle warranty. The bright metal moldings on the vehicle are aluminum, chrome, or stainless steel.

To prevent damage always follow these cleaning instructions:

  • Be sure the molding is cool to the touch before applying any cleaning solution.
  • Use only approved cleaning solutions for aluminum, chrome, or stainless steel.

Some cleaners are highly acidic or contain alkaline substances and can damage the moldings.

  • Always dilute a concentrated cleaner according to the manufacturer’s
  • Do not use cleaners that are not intended for automotive use.
  • Use a nonabrasive wax on the vehicle after washing to protect and extend the molding finish.

Customer Information

Customer Satisfaction Procedure

Your satisfaction and goodwill are important to your dealer and to GMC. Normally, any concerns with the sales transaction or the operation of the vehicle will be resolved by your dealer’s sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur. If your concern has not been resolved to your satisfaction, the following steps should be taken:

STEP ONE : Discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level. If the matter has already been reviewed with the sales, service, or parts manager, contact the owner of your dealership or the general manager.

STEP TWO : If after contacting a member of dealership management, it appears your concern cannot be resolved by your dealership without further help, in the U.S., call 1-800-462-8782. In Canada, call General Motors of Canada Customer Care Centre at 1-800-263-3777 (English), or 1-800-263-7854 (French).
We encourage you to call the toll-free number in order to give your inquiry prompt attention. Have the following information available to give the Customer Assistance representative:

  • Vehicle Identification Number (VIN). This is available from the vehicle registration or title, or the plate at the top left of the instrument panel and visible through the windshield.
  • Dealership name and location.
  • Vehicle delivery date and present

When contacting GMC, remember that your concern will likely be resolved at a dealer’s facility. That is why we suggest following Step One first.

STEP THREE — U.S. Owners: Both General Motors and your dealer are committed to making sure you are completely satisfied with your new vehicle. However, if you continue to remain unsatisfied after following the procedure outlined in Steps One and Two, you can file with the Better Business Bureau (BBB) AUTO LINE Program to enforce your rights. The BBB AUTO LINE Program is an out-of-court program administered by the BBB National Programs, Inc. to settle automotive disputes regarding vehicle repairs or the interpretation of the New Vehicle Limited Warranty. Although you may be required to resort to this informal dispute resolution program prior to filing a court action, use of the program is free of charge and your case will generally be heard within 40 days. If you do not agree with the decision given in your case, you may reject it and proceed with any other venue for relief available to you.

Vehicle Data Recording and Privacy

The vehicle has a number of computers that record information about the vehicle’s performance and how it is driven or used. For example, the vehicle uses computer modules to monitor and control engine and transmission performance, to monitor the conditions for airbag deployment and deploy them in a crash, and, if equipped, to provide antilock braking to help the driver control the vehicle. These modules may store data to help the dealer technician service the vehicle or to help GM improve safety or features. Some modules may also store data about how the vehicle is operated, such as rate of fuel consumption or average speed. These modules may retain personal preferences, such as radio presets, seat positions, and temperature settings.

Cybersecurity

GM collects information about the use of your vehicle including operational and safety-related information. We collect this information to provide, evaluate, improve, and troubleshoot our products and services and to develop new products and services.

The protection of vehicle electronics systems and customer data from unauthorized outside electronic access or control is important to GM. GM maintains appropriate security standards, practices, guidelines and controls aimed at defending the vehicle and the vehicle service ecosystem against unauthorized electronic access, detecting possible malicious activity in related networks, and responding to suspected cybersecurity incidents in a timely, coordinated and effective manner. Security incidents could impact your safety or compromise your private data. To minimize security risks, please do not connect your vehicle electronic systems to unauthorized devices or connect your vehicle to any unknown or untrusted networks (such as Bluetooth, WIFI or similar technology). In the event you suspect any security incident impacting your data or the safe operation of your vehicle, please stop operating your vehicle and contact your dealer.

Event Data Recorders

This vehicle is equipped with an Event Data Recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as:

  • How various systems in your vehicle were operating;
  • Whether or not the driver and passenger safety belts were buckled/fastened;
  • How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
  • How fast the vehicle was travelling.

These data can help provide a better understanding of the circumstances in which crashes and injuries occur.

Note
EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.

To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR.
GM will not access these data or share it with others except: with the consent of the vehicle owner or, if the vehicle is leased, with the consent of the lessee; in response to an official request by police or similar government office; as part of GM’s defense of litigation through the discovery process; or, as permitted by law. Data that GM collects or receives may also be used for GM research needs or may be made available to others for research purposes, where a need is shown and the data is not tied to a specific vehicle or vehicle owner.

OnStar

If the vehicle is equipped with OnStar and has an active service plan, additional data may be collected and transmitted through the OnStar system. This includes information about the vehicle’s operation; collisions involving the vehicle; the use of the vehicle and its features, including infotainment; and the location and approximate GPS speed of the vehicle. Refer to the OnStar Terms and Conditions and Privacy Statement on the OnStar website. See OnStar Additional Information 0 392

Infotainment System

If the vehicle is equipped with a navigation system as part of the infotainment system, use of the system may result in the storage of destinations, addresses, telephone numbers, and other trip information. See the infotainment section for information on stored data and for deletion instructions.

Reporting Safety Defects to the United States Government

If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying General Motors.

If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer or General Motors.
To contact NHTSA, you may call the Vehicle Safety Hotline toll-free at 1-888-327-4236 (TTY: 1-800-424-9153); go to https://www.safercar.gov; or write to:

Administrator, NHTSA

1200 New Jersey Avenue, S.E. Washington, D.C. 20590

You can also obtain other information about motor vehicle safety from https://www.safercar.gov.

Reporting Safety Defects to the Canadian Government

If you live in Canada, and you believe that the vehicle has a safety defect, notify Transport Canada immediately, and notify General Motors of Canada Company. Call Transport Canada at
1-800-333-0510; go to:

Vehicle Data Recording and Privacy

The vehicle has a number of computers that record information about the vehicle’s performance and how it is driven or used. For example, the vehicle uses computer modules to monitor and control engine and transmission performance, to monitor the conditions for airbag deployment and deploy them in a crash, and, if equipped, to provide antilock braking to help the driver control the vehicle. These modules may store data to help the dealer technician service the vehicle or to help GM improve safety or features. Some modules may also store data about how the vehicle is operated, such as rate of fuel consumption or average speed. These modules may retain personal preferences, such as radio presets, seat positions, and temperature settings.

Cybersecurity

GM collects information about the use of your vehicle including operational and safety related information. We collect this information to provide, evaluate, improve, and troubleshoot our products and services and to develop new products and services.

The protection of vehicle electronics systems and customer data from unauthorized outside electronic access or control is important to GM. GM maintains appropriate security standards, practices, guidelines and controls aimed at defending the vehicle and the vehicle service ecosystem against unauthorized electronic access, detecting possible malicious activity in related networks, and responding to suspected cybersecurity incidents in a timely, coordinated and effective manner. Security incidents could impact your safety or compromise your private data. To minimize security risks, please do not connect your vehicle electronic systems to unauthorized devices or connect your vehicle to any unknown or untrusted networks (such as Bluetooth, WIFI or similar technology). In the event you suspect any security incident impacting your data or the safe operation of your vehicle, please stop operating your vehicle and contact your dealer.

Event Data Recorders

This vehicle is equipped with an Event Data Recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as:

  • How various systems in your vehicle were operating;
  • Whether or not the driver and passenger safety belts were buckled/fastened;
  • How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
  • How fast the vehicle was traveling.

These data can help provide a better understanding of the circumstances in which crashes and injuries occur.

Note
EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.
