WHAT IS PRE-COLLISION
ASSIST
Pre-collision assist detects and warns ofapproaching hazards in the roadway. Thesystem provides multiple levels ofassistance to help avoid a collision if yourvehicle is rapidly approaching anotherstationary vehicle, a vehicle traveling in thesame direction as yours, or a pedestrian orcyclist within your driving path.
HOW DOES PRE-COLLISION
ASSIST WORK
The system warns the driver of potentialhazards by providing three levels ofassistance.
If your vehicle is rapidly approachingpotential hazards the system provides thefollowing levels of functionality:
1.Alert.
2.Brake Support.
3.Automatic Emergency Braking.
Alert: When active, a flashingvisual warning appears and anaudible warning tone sounds.
Brake Support: The system is designedto help reduce the impact speed bypreparing the brakes for rapid braking. Thesystem does not automatically apply thebrakes. If you press the brake pedal, thesystem could apply additional braking upto maximum braking force, even if youlightly press the brake pedal.
Automatic Emergency Braking:Automatic emergency braking mayactivate if the system determines that acollision is imminent.
Note:If you perceive the pre-collision assistalerts as being too frequent or disturbing,then you can reduce the alert sensitivity.Setting the low sensitivity would result infewer and later warnings of a potentialforward collision. The manufacturerrecommends using the high sensitivitysetting where possible.
Note:Automatic emergency brakingperformance is not affected by thesensitivity setting.
Each system has various levels ofdetection capabilities. See Pre-CollisionAssist Limitations (page 329).
