Advance warning
The system warns the driver with a warning chime and a message in the instrument cluster display
⇒Fig.128 if it detects a possible collision with a vehicle or a pedestrian.
The warning period varies according to the traffic situation and your driving style.
Brake or take action to avoid the vehicle ahead!
However, do not rely solely on Front Assist. Under certain conditions, the reactions of Front Assist
may be unexpected or delayed from the driver's viewpoint. Always pay attention and take over if nec‐
essary ⇒ .
Immediate warning
If you fail to react accordingly to the advance warning, Front Assist may initiate a short active braking
maneuver. In this case you will notice brief, jerky braking of the vehicle to warn you of an impending
collision.
The timing of this alert can vary, depending on the traffic situation and your driving style.
Automatic braking
If you should also fail to react to the immediate warning, Front Assist can initiate an automatic braking
maneuver that will abruptly decelerate the vehicle with an increased braking force. The emergency
braking maneuver occurs shortly before a potential collision to reduce vehicle speed and help to mini‐
mize the effects of a collision.
