Toyota Dynamic radar cruise control Guide

This dynamic radar cruise control detects the pres-ence of vehicles ahead, determines the current vehi-cle-to-vehicle distance, and operates to maintain a suit-able distance from the vehi-cle ahead. The desired vehicle-to-vehicle distance can be set by operating the vehicle-to-vehicle distance switch.

Use the dynamic radar cruise control only on high-ways and expressways.

WARNING

For safe use

Driving safely is solely the responsibility of the driver. Do not overly rely on this system, and pay careful attention to the surrounding conditions in order to ensure safe driving.
The dynamic radar cruise con-trol provides driving assistance to reduce the driver’s burden. However, there are limitations to the assistance provided. Read the following items care-fully. Do not overly rely on this system and always drive care-fully.

Conditions under which the sys-tem may not operate correctly:

WARNING

Set the speed appropriately according to the speed limit, traffic flow, road conditions, weather conditions, etc. The driver is responsible for confirm-ing the set speed.
Even if the system is operating correctly, the condition of a pre-ceding vehicle as recognized by the driver and detected by the system may differ. Therefore, it is necessary for the driver to pay attention, assess risks, and ensure safety. Over-reliance on this system to drive the vehicle safely may lead to an accident resulting in death or serious injury.

Precautions for the driving assist systems
Observe the following precau-tions, as there are limitations to the assistance provided by the system. Over-reliance on this sys-tem may lead to an accident resulting in death or serious injury.

Details of support provided for the driver’s vision
The dynamic radar cruise con-trol is only intended to help the driver in determining the dis-tance between the driver’s own vehicle and a designated pre-ceding vehicle. It is not a sys-tem which allows for careless or inattentive driving, and is not a system which assists in poor visibility conditions.
The driver must pay attention to their surroundings, even when the vehicle stops.
Details of support provided for the driver’s judgement
The dynamic radar cruise con-trol determines whether the dis-tance between the driver’s own vehicle and a designated pre-ceding vehicle is within a set range. It is not capable of mak-ing any other type of judgement. Therefore, it is absolutely nec-essary for the driver to remain vigilant and to determine whether or not there is a possi-bility of danger.
Details of support provided for the driver’s operation
The dynamic radar cruise con-trol does not include functions which will prevent or avoid colli-sions with vehicles ahead of your vehicle. Therefore, if there is ever any possibility of danger, the driver must take immediate and direct control of the vehicle and act appropriately in order to ensure safety.

WARNING

Situations in which the dynamic radar cruise control should not be used
Do not use the dynamic radar cruise control in the following situ-ations. As the system will not be able to provide appropriate con-trol, using it may lead to an acci-dent resulting in death or serious injury.

Roads where there are pedes-trians, cyclists, etc.
When driving on a highway or expressway entrance or exit
When the approach warning sounds frequently
Situations in which the sensors may not operate properly:
When it is necessary to disable the system:

When towing another vehicle

When lift up

Basic functions

Constant speed cruising:
When there are no vehicles ahead The vehicle drives at the speed set by the driver. If the set vehicle speed is exceeded while driving down a hill, the set vehicle speed display will blink and a buzzer will sound.
Deceleration and follow-up cruising When a preceding vehicle driving slower than the set vehicle speed is detected When a vehicle is detected driving ahead of your vehicle, the vehicle auto-matically decelerates and if a greater reduction in vehicle speed is neces-sary, the brakes are applied (the stop lights will come on at this time). The vehicle is controlled to maintain the vehicle-to-vehicle distance set by the driver, in accordance with changes in the speed of the preceding vehicle. If vehicle deceleration is not sufficient and the vehicle approaches the vehicle ahead, the approach warning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower than the set vehicle speed The vehicle accelerates until the set vehicle speed is reached and then resumes constant speed cruising.
Starting off (vehicles with brake-hold):
If a preceding vehicle stops, the vehicle will also stop (controlled stop). After the preceding vehicle starts off, pressing the “RES” switch or depressing the accelerator pedal will resume follow-up cruising (start off operation). If a start off operation is not performed, the controlled stop will continue.

The dynamic radar cruise control indicator will illuminate.
Using the accelerator pedal, accelerate or decelerate to the desired vehicle speed (approximately 20 mph [30 km/h] or more), and press the driving assist switch to set the set vehicle speed.

The set vehicle speed will be dis-played on the multi-information dis-play. The vehicle speed at the moment the switch is released will be the set vehicle speed.

Adjusting the set vehicle speed

Adjusting the set vehicle speed using the switches
To change the set vehicle speed, press the “+” switch or “-” switch until the desired speed is displayed.

Increase set vehicle speed
Decrease set vehicle speed
Short press adjustment: Press the switch Long press adjustment: Press and hold the switch until the desired set vehicle speed is reached. The set vehicle speed will increase or decrease as follows:

For U.S.A.
Short press adjustment: Increases or decreases by 1 mph (1.6 km/h) each time the switch is pressed Long press adjustment: Increases or decreases in 1 mph (1.6 km/h) increments continuously while the switch is pressed and held

Except for U.S.A.
Short press adjustment: By 1 km/h (0.6 mph) or 1 mph (1.6 km/h) each time the switch is pressed Long press adjustment: Increases or decreases in 5 km/h (3.1 mph) or 5 mph (8 km/h) increments continu-ously while the switch is pressed and held

Increasing the set vehicle speed using the accelerator pedal

Depress the accelerator pedal to accelerate the vehi-cle to the desired vehicle speed.
Press the “+” switch.

Canceling/resuming control

Press the cancel switch or driving assist switch to cancel control.
Control will also be canceled if the brake pedal is depressed.
(Vehicles with brake-hold: If the vehicle has been stopped by sys-tem control, depressing the brake pedal will not cancel control.)
Press the “RES” switch to resume control.

Changing the vehicle-to-vehicle distance
Each time the switch is pressed, the vehicle-to-vehicle distance setting will change as follows: If a preceding vehicle is detected, the preceding vehicle mark will be displayed.

Illustra- tion Number	Vehicle- to-vehi- cle distance	Approximate Distance (Vehi- cle Speed: 60 mph [100 km/h])
1	Extra long	Approximately 200 ft. (60 m)
2	Long	Approximately 145 ft. (45 m)
3	Medium	Approximately 100 ft. (30 m)
4	Short	Approximately 85 ft. (25 m)

The actual vehicle-to-vehicle dis-tance varies in accordance with the vehicle speed. Also, when the vehi-cle is stopped by system control, it will be stopped at a certain distance from the preceding vehicle, depending on the situation, regard-less of the setting.

Operating conditions

Vehicles with an automatic trans-mission: The shift lever is in D.
Vehicles with a manual transmis-sion: The shift lever is in 2nd gear or higher.
The desired set speed can be set when the vehicle speed is approx-imately 20 mph (30 km/h) or more.
If the vehicle speed is set while driving at below approximately 20 mph (30 km/h), the set vehicle speed will be approximately 20 mph (30 km/h).
If the vehicle speed is set while driving at a speed that exceeds the system’s upper limit, the set vehicle speed will be the system’s upper limit.

Accelerating after setting the vehicle speed
As with normal driving, acceleration can be performed by depressing the accelerator pedal. After accelerat-ing, the vehicle will return to the set vehicle speed. However, while in vehicle-to-vehicle distance control mode, the vehicle speed may decrease to below the set vehicle speed in order to maintain the dis-tance from the preceding vehicle.

Shift position selection (vehi-cles with a manual transmis-sion)
Select an appropriate shift position according to the vehicle speed. If the engine speed becomes exces-sively high or low, control may be canceled automatically.

When the vehicle is stopped by system control during follow-up cruising (vehicles with brake-hold)

When the “RES” switch is pressed while the vehicle is stopped by system control, if the preceding vehicle starts off within approxi-mately 3 seconds, follow-up cruis-ing will resume.
If the preceding vehicle starts off within approximately 3 seconds of the vehicle being stopped by sys-tem control, follow-up cruising will resume.

Automatic cancelation of vehi-cle-to-vehicle distance control mode
In the following situations, vehicle-to-vehicle distance control mode will be canceled automatically:

Vehicles with a manual transmis-sion: When the vehicle speed drops below approximately 20 mph (30 km/h)
When the brake control or output restriction control of a driving sup-port system operates (For exam-ple: Pre-Collision System, drive-start control)
Vehicles with a manual transmis-sion: When the shift lever is in N or the clutch pedal is depressed for more than a certain amount of time
When the parking brake has been operated
When the driver’s seat belt is unfastened
When the Pre-Collision System is disabled
When the vehicle is stopped by system control on a steep incline
When any of the following are detected while the vehicle is stopped by system control:
The driver’s seat belt is unfas-tened
The driver’s door is opened
Approximately 3 minutes have elapsed since the vehicle was stopped

The parking brake may be actived automatically.

Situations in which some or all of the functions of the system cannot operate:

Dynamic radar cruise control system warning messages and buzzers

Preceding vehicles that the sen-sor may not detect correctly
In the following situations, depend-ing on the conditions, if the system cannot provide sufficient decelera-tion or acceleration is necessary, operate the brake pedal or accelerator pedal. As the sensor may not be able to correctly detect these types of vehi-cles, the approach warning
may not operate.

When a vehicle cuts in front of your vehicle or changes lanes away from your vehicle extremely slowly or quickly
When changing lanes
When a preceding vehicle is driv-ing at a low speed
When a vehicle is stopped in the same lane as the vehicle
When a motorcycle is traveling in the same lane as the vehicle

Conditions under which the system may not operate cor-rectly
In the following situations, operate the brake pedal (or accelerator pedal, depending on the situation) as necessary. As the sensor may not be able to correctly detect a vehicle, the sys-tem may not operate properly.

When a preceding vehicle brakes suddenly
Vehicles with brake-hold: When changing lanes at low speeds, such as in a traffic jam

Approach warning
In situations where the vehicle approaches a preceding vehicle and the system cannot provide sufficient deceleration, such as if a vehicle cuts in front of the vehicle, a warning display will flash and a buzzer will sound to alert the driver. Depress the brake pedal to ensure appropri-ate vehicle-to-vehicle distance.

Warnings may not occur when
In the following situations, the warning may not operate even though the vehicle-to-vehicle distance is short.

When the preceding vehicle is traveling at the same speed or faster than your vehicle
When the preceding vehicle is traveling at an extremely low speed
Immediately after the vehicle speed has been set
When the accelerator pedal is depressed

Curve speed reduction function
When a curve is detected, the vehicle speed will begin being reduced. When the curve ends, the vehicle speed reduction will end. Depending on the situation, the vehicle speed will then return to the set vehicle speed. In situations where vehicle-to-vehi-cle distance control needs to oper-ate, such as when a preceding vehicle cuts in front of your vehicle, the curve speed reduction function will be canceled.

Situations in which the curve speed reduction function may not operate
In situations such as the following, the curve speed reduction function may not operate:

When the vehicle is being driven around a gentle curve
When the accelerator pedal is being depressed
When the vehicle is being driven around an extremely short

curve Support for lane change
If your vehicle is being driven at approximately 50 mph (80 km/h) or more and a lane change to the passing lane is performed, when the turn signal lever is operated and the lane is changed, the vehicle will accel-erate up to the set speed to assist in overtaking. The system’s recognition of which lane is the passing lane may be based solely on the location of the steering wheel in the vehicle (left-hand drive/right-hand drive). If the vehicle is driven in a location where the passing lane is on the opposite side of that where the vehicle was originally sold, the vehicle may accelerate when the turn signal lever is operated away from the passing lane. (e.g. The vehicle was manufactured for a right-hand traf-fic location, but is being driven in a left-hand traffic location. The vehi-cle may accelerate when the turn signal lever is operated to the right.) If your vehicle is being driven at approximately 50 mph (80 km/h) or more and the lane is changed to that with a vehicle traveling slower than your vehicle, when the turn signal lever is operated the vehicle will gradually decelerate to assist in changing lanes.
