Honda Civic Hatchback 2022 Collision Alert Stages User Manual
Collision Alert Stages
The system has three alert stages for a possible collision. However, depending on circumstances, the CMBSTM may not go through all of the stages before initiating the last stage.
Distance between vehicles
|The sensors detect a vehicle||Audible & Visual WARNINGS||Braking|
Your Vehicle Vehicle Ahead
There is a risk of a collision with the vehicle ahead of you.
|When in Long, visual and audible alerts come on at a longer distance from a vehicle ahead than in Normal setting, and in Short, at a shorter distance than in Normal.||
The risk of a collision has increased, time to respond is reduced.
Visual and audible alerts.
The CMBSTM determines that a collision is unavoidable.
CMBSTM On and Off
When you turn the CMBSTM on and off, do the following.
- Press the safety support switch.
Models with A-type meter
- Roll the left selector wheel to the symbol and push it.
Models with B-type meter
- Roll the right selector wheel to the symbol and push it.
A message appears on the driver information interface when the system turns on or off. A checkmark appears in the box and the color of the symbol changes to green when the system is on. The check mark disappears and the color of the symbol changes to gray when the system is off.
The CMBSTM is turned on every time you start the engine, even if you turned it off the last time you drove the vehicle. You cannot turn the CMBSTM off while driving. The CMBSTM may automatically shut off, and the safety support indicator (amber) will come and stay on under certain conditions:
- CMBSTM Conditions and Limitations P. 504
- The CMBSTM is not activated for about 15 seconds after the engine starts.
- You can also select safety support content from the driver information interface.
- Driver Information Interface P. 116
- Driver Information Interface (Right Side Area)
The Vehicle Stability Assist TM (VSA®) system, Vehicle Stability Assist TM (VSA®) OFF, Adaptive Cruise Control (ACC)*, Adaptive Cruise Control (ACC) with Low Speed Follow*, low tire pressure/TPMS* and safety support indicators may come on in amber along with a message in the gauge when you set the power mode to ON after reconnecting the battery. Drive a short distance at more than 12 mph (20 km/h). Each indicator should go off. If any do not, have your vehicle checked by a dealer.
CMBSTM Conditions and Limitations
The system may automatically shut off and the safety support indicator (amber) will come on under certain conditions. Some examples of these conditions are listed below. Other conditions may reduce some of the CMBSTM functions.
Front Wide-View Camera
- Driving in bad weather (rain, fog, snow, etc.).
- Sudden changes between light and dark, such as the entrance or exit of a tunnel or the shadows of trees, buildings, etc.
- Driving into low sunlight (e.g., at dawn or dusk).
- Strong light is reflected onto vehicles, pedestrians, moving bicycles, or road surfaces.
- Water is sprayed by or snow blown from a vehicle ahead.
- Driving at night or in a dark place such as a tunnel (due to low-light conditions, vehicles, pedestrians, or moving bicycles may not be illuminated).
- Driving on curvy, winding, undulating, or sloping roads.
- There is a film of water or puddles on the road surface.
- Driving on rutted roads (snowy or unpaved roads, etc.).
- Your vehicle is strongly shaken on uneven road surfaces.
Have your vehicle checked by a dealer if you find any unusual behavior of the system (e.g., the warning message appears too frequently).
- Tire chains are installed.
- Driving at night or in a dark place (e.g., a tunnel) with the headlights off.
- The front of the camera is covered by dirt, fog, rain, mud, wet snow, seals, accessories, stickers, or film on the windshield.
- There is residue on the windshield from the windshield wipers.
- When lighting is weak due to dirt covering the headlight lenses, or there is poor visibility in a dark place due to the headlights being improperly adjusted.
- An abnormal tire or wheel condition (incorrect sizes, varied sizes or construction, improperly inflated, compact spare tire, etc.).
- The suspension has been modified.
Examples of limitations on the correct detection of the camera due to the condition of the vehicle ahead of you, oncoming vehicles, pedestrians, or moving bicycles
- The distance between your vehicle and the vehicle ahead of you, oncoming vehicle, pedestrian, or moving bicycle ahead of you is too short.
- The vehicle ahead of you, an oncoming vehicle, pedestrian, or moving bicycle suddenly cuts in front of or jumps out in front of you.
- The bicycle is stopped.
- The oncoming vehicle or vehicle ahead of you is sideways.
- When the vehicle ahead of you, oncoming vehicle, pedestrian, or moving bicycle blends in with the background, preventing the system from recognizing them.
- When several pedestrians or bicycles are moving ahead of you in a group.
- When a pedestrian or moving bicycle crosses the road too quickly.
- A pedestrian or moving bicycle approaches from the opposite direction.
- The headlights of the vehicle ahead of you or oncoming vehicle are lit on one side or not lit on either side in a dark place.
- When part of a pedestrian (heads, limbs, etc.) is hidden by load.
- When a pedestrian is bent over or squatting, when their hands are raised, or they are running.
- When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about 6.6 feet (2 meters) in height.
- When the pedestrian is pushing a stroller or bicycle.
Make sure that all the tires are of the same specified size, type and brand, and that they are evenly worn. If you use tires of different sizes, types, brands, or degree of wear, the system may not work properly. Do not modify the suspension. Altering the height of the vehicle may prevent the system from working properly.
Examples of other limitations on detection or system operation
- When the vehicle ahead of you is a small motorcycle, motorcycle with a sidecar, wheelchair, or another specially shaped vehicle.
- When a vehicle is lower in the rear than the front such as trucks that are not carrying a load, or a narrow vehicle.
- When the vehicle ahead of you, oncoming vehicle, pedestrian or moving bicycle is not in front of the vehicle.
- The speed difference between your vehicle and the vehicle ahead of you, oncoming vehicle, pedestrian or moving bicycle is significantly large.
- When the vehicle or moving bicycle in front of you slows suddenly.
- When the driver operates the brake pedal and steering wheel to avoid a collision.
- When you approach the vehicle ahead of you, oncoming vehicle, pedestrians or moving bicycles while accelerating rapidly or operating the steering wheel (except when turning left at an intersection etc.)
- When the moving bicycle is a child-sized bicycle, folding bicycle, three-wheeler or another bicycle with small tires, or a long bicycle like a tandem bicycle.
- When the camera cannot correctly identify the shape of the vehicle ahead of you, an oncoming vehicle, pedestrian, or moving bicycle.
- When the minimum ground clearance of a vehicle ahead of you is extremely high.
When there is a possibility of a frontal collision with the oncoming vehicle while turning left, the CMBSTM is activated. However, it may not be activated if you suddenly turn the steering wheel.
