Using the Collision Warning System
WARNING
The collision warning system's brake
support can only help reduce the
speed at which a collision occurs if
the driver applies the vehicle's brakes. The
brake pedal must be pressed just like any
typical braking situation.
The warning system and chime can be
turned on and off separately by using the
information display control. See General
Information (page 82).
Note: If the system cannot be turned off in
a vehicle equipped with MyKey®, See
Principle of Operation (page 48).
