WHAT IS PRE-COLLISION ASSIST
Pre-collision assist detects and warns of approaching hazards in the roadway. If your vehicle is rapidly approaching another stationary vehicle, a vehicle traveling in the same direction as yours, or a pedestrian within your driving path, the system provides multiple levels of assistance to help avoid a collision.
HOW DOES PRE-COLLISION ASSIST WORK
The system warns the driver of potential hazards by providing three levels of assistance.
If your vehicle is rapidly approaching potential hazards the system provides the following levels of functionality:
- Alert.
- Brake support.
- Automatic emergency braking.
Brake Support: The system helps reduce the impact speed by preparing the brakes for rapid braking. The system does not automatically apply the brakes. If you press the brake pedal, the system may apply additional braking up to maximum braking force, even if you lightly press the brake pedal.
Automatic Emergency Braking: Automatic emergency braking may activate if the system determines that a collision is imminent.
Note: If the pre-collision assist alerts are too frequent or disturbing, you can reduce the alert sensitivity. Setting the low sensitivity results in fewer and later warnings of a potential forward collision. The manufacturer recommends using the high sensitivity setting where possible.
Note: Automatic emergency braking performance is not affected by the sensitivity setting.
Each system has various levels of detection capabilities. See Pre-Collision Assist Limitations.
PRE-COLLISION ASSIST PRECAUTIONS
 WARNING: You are responsible for controlling your vehicle at all times. The system is designed to be an aid and does not relieve you of your responsibility to drive with due care and attention. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death. WARNING: The system does not detect vehicles moving in a different direction or animals. Apply the brakes when necessary. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death. WARNING: The system does not operate during hard acceleration or steering. Failure to take care may lead to a crash or personal injury. WARNING: The system may operate with reduced function during cold and inclement weather conditions. Snow, ice, rain, spray and fog can adversely affect the system. Keep the front camera and radar free of snow and ice. Failure to follow this instruction may result in the loss of control of your vehicle, serious personal injury or death. WARNING: Take additional care if your vehicle is heavily loaded or you are towing a trailer. These conditions could result in reduced performance of this system. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death. WARNING: The system cannot help prevent all crashes. Do not rely on this system to replace driver judgment and the need to maintain a safe distance and speed. WARNING: System performance could be reduced in situations where the vehicle camera has limited detection capability. These situations include but are not limited to direct or low sunlight, vehicles at night without tail lights, unconventional vehicle types, pedestrians or cyclists with complex backgrounds, running pedestrians or fast moving cyclists, partly obscured pedestrians or cyclists, pedestrians or cyclists that the system cannot distinguish from a group. Failure to take care may result in the loss of control of your vehicle, personal injury or death. |
PRE-COLLISION ASSIST LIMITATIONS
Pre-collision assist depends on the detection ability of its camera and sensors. Any obstructions or damage to these areas can limit detection or prevent the system from functioning. See Locating the Pre-Collision Assist Sensors.
The system is active at 3 mph (5 km/h) and above.
Note: Brake support and automatic emergency braking are active up to the maximum speed of the vehicle.
Pedestrian Detection Limitations
Pedestrian detection is active at speeds up to 50 mph (80 km/h).
Pedestrian detection functions optimally when detected hazards are clearly identifiable. System performance may reduce in situations where pedestrians are running, partly obscured, have a complex background, or cannot be distinguished from a group.
Cyclist Detection Limitations
Cyclist detection is active at speeds up to 50 mph (80 km/h).
Cyclist detection functions optimally when detected hazards are clearly identifiable. The system’s detection level may be less in situations where cyclists are moving fast, partly hidden, have a complex background, or the system cannot distinguish the cyclist from a group.
Intersection Assist
The pre-collision assist system may operate in a scenario where you are turning across an oncoming vehicle’s path. Detection of vehicles driving in an oncoming direction is active if your vehicle is driving at speeds up to 50 mph (80 km/h).
SWITCHING PRE-COLLISION ASSIST ON AND OFF
You cannot switch the system off.
Adjusting the Pre-Collision Assist Settings
You can adjust the following settings by using the controls in the pre-collision assist menu:
- Change alert and distance alert sensitivity to one of three possible settings.
- Switch distance indication and alert on or off.
- If required, switch automatic emergency braking on or off.
- If required, switch evasive steering assist on or off.
Note: Automatic emergency braking and evasive steering automatically turns on every time you switch the ignition on.
Note: If you switch automatic emergency braking off, evasive steering assist switches off.
LOCATING THE PRE-COLLISION ASSIST SENSORS
1. Camera.2. Radar sensor. |
If a message regarding a blocked sensor or camera appears in the information display, something is obstructing the radar signals or camera images. The radar sensor is behind the fascia cover in the center of the lower grille. With a blocked sensor or camera, the system may not function, or performance may reduce. See Pre-Collision Assist – Information Messages.
Note: Proper system operation requires a clear view of the road by the camera. Repair any windshield damage in the area of the camera’s field of view.
Note: If something hits the front end of your vehicle or damage occurs and your vehicle has a radar sensor, the radar sensing zone could change. This could cause missed or false vehicle detections. Have your vehicle serviced to have the radar checked for proper coverage and operation.
Note: If your vehicle detects excessive heat at the camera or a potential misalignment condition, a message could display in the information display indicating temporary sensor unavailability. When operational conditions are correct, the message deactivates. For example, when the ambient temperature around the sensor decreases or the sensor recalibrates successfully.
