WARNING   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   WARNING:  The system does not detect vehicles that are driving in a different direction, cyclists or animals. Failure to take care may result in the loss of control of your vehicle, serious personal injury or death.
WARNING   WARNING:  The system does not operate during hard acceleration or steering. Failure to take care may lead to a crash or personal injury.
WARNING   WARNING:  The system may fail or operate with reduced function during cold and severe 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 take care may result in the loss of control of your vehicle, serious personal injury or death.
WARNING   WARNING:  In situations where the vehicle camera has limited detection capability, this may reduce system performance. These situations include but are not limited to direct or low sunlight, vehicles at night without tail lights, unconventional vehicle types, pedestrians with complex backgrounds, running pedestrians, partly obscured pedestrians, or pedestrians that the system cannot distinguish from a group. Failure to take care may result in the loss of control of your vehicle, serious personal injury or death.
WARNING   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.

Using the Pre-Collision Assist System
The system is active at speeds above approximately 3 mph (5 km/h) and pedestrian detection is active at speeds up to 50 mph (80 km/h).
Missing Image
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 is designed to provide three levels of functionality:
  1. Alert
  1. Brake Support
  1. Active Braking
Missing Image
Alert: When active, a flashing visual warning appears and an audible warning tone sounds.
Brake Support: The system is designed to help reduce the impact speed by preparing the brakes for rapid braking. Brake support does not automatically apply the brakes. If you press the brake pedal, the system could apply additional braking up to maximum braking force, even if you lightly press the brake pedal.
Active Braking: Active braking may activate if the system determines that a collision is imminent. The system may help the driver reduce impact damage or avoid the crash completely.
Note:   Brake Support and Active Braking are active at speeds up to 75 mph (120 km/h). If the vehicle is equipped with a radar sensor, included with Adaptive Cruise Control, then Brake Support and Active Braking are active up to the maximum speed of the vehicle.
Note:   If you perceive Pre-Collision Assist alerts as being too frequent or disturbing, then you can reduce the alert sensitivity, though the manufacturer recommends using the highest sensitivity setting where possible. Setting lower sensitivity would lead to fewer and later system warnings.
Distance Indication and Alert
Distance Indication and Alert is a function that provides the driver with a graphical indication of the time gap to other preceding vehicles traveling in the same direction. The Distance Indication and Alert screen in the display screen shows one of the graphics that follow.
Missing Image
If the time gap to a preceding vehicle is small, a red visual indication displays to the driver.
Note:   Distance Indication and Alert deactivates and the graphics do not display when Adaptive Cruise Control is active.

Speed   Sensitivity   Graphics   Distance Gap   Time Gap  
62 mph (100 km/h)   Normal   Grey   >82 ft (25 m)   >0.9sec  
62 mph (100 km/h)   Normal   Yellow   56–82 ft (17–25 m)   0.6sec — 0.9sec  
62 mph (100 km/h)   Normal   Red   <56 ft (17 m)   <0.6sec  

Evasive Steering Assist
If your vehicle is rapidly approaching a stationary vehicle or a vehicle traveling in the same direction as your vehicle, the system is designed to help you steer around the vehicle.
The system only activates when all of the following occur:
  • The Pre-Collision Assist system detects a vehicle ahead and starts to apply Active Braking.
  • You turn the steering wheel in an attempt to steer around the vehicle.
After you turn the steering wheel, the system applies additional steering torque to help you steer around the vehicle. After you pass the vehicle, the system applies steering torque in the opposite direction to encourage you to steer back into the lane. The system deactivates after you fully pass the vehicle.
Note:   The system does not automatically steer around a vehicle. If you do not turn the steering wheel, the system does not activate.
Note:   The system does not activate if the distance to the vehicle ahead is too small and a crash cannot be avoided.
Adjusting the Pre-Collision Assist Settings
The following settings can be adjusted by using the information display controls.
  • You can change Alert and Distance Alert sensitivity to one of three possible settings.
  • You can switch Distance Indication and Alert on or off.
  • If required, you can switch Active Braking on or off.
  • If required, you can switch Evasive Steering Assist on or off.
Note:   Active Braking and Evasive Steering Assist automatically turn on every time you switch the ignition on.
Note:   If you switch Active Braking off, Evasive Steering Assist turns off.
Blocked Sensors
Missing Image
1Camera.
2Radar sensor (if equipped).
If a message regarding a blocked sensor or camera appears in the information display, the radar signals or camera images are obstructed. If your vehicle is equipped with a radar sensor, it is located behind the fascia cover in the center of the lower grille. With a blocked sensor or camera, the Pre-Collision Assist system may not function or performance may reduce. The following table lists possible causes and actions for when this message displays.
Camera Troubleshooting

Cause   Action  
The windshield in front of the camera is dirty or obstructed in some way.   Clean the outside of the windshield in front of the camera.  
The windshield in front of the camera is clean but the message remains in the display screen.   Wait a short time. It may take several minutes for the camera to detect that there is no obstruction.  

Radar Troubleshooting (If Equipped)

Cause   Action  
The surface of the radar in the grille is dirty or obstructed in some way.   Clean the grille surface in front of the radar or remove the object causing the obstruction.  
The surface of the radar in the grille is clean but the message remains in the display screen.   Wait a short time. It may take several minutes for the radar to detect that there is no obstruction.  
Heavy rain, spray, snow or fog is interfering with the radar signals.   The Pre-Collision Assist system is temporarily disabled. Pre-Collision Assist automatically reactivates a short time after the weather conditions improve.  
Swirling water or snow or ice on the surface of the road may interfere with the radar signals.   The Pre-Collision Assist system is temporarily disabled. Pre-Collision Assist automatically reactivates a short time after the weather conditions improve.  
Radar is out of alignment due to a front end impact.   Contact an authorized dealer to have the radar checked for proper coverage and operation.  

Note:   Proper system operation requires a clear view of the road by the camera. Have any windshield damage in the area of the camera's field of view repaired.
Note:   If something hits the front end of your vehicle or damage occurs and your vehicle is equipped with a radar sensor, the radar sensing zone may change. This could cause missed or false detections. Contact an authorized dealer to have the radar checked for proper coverage and operation.
