System Limitations
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.
Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision warning.
These include:
•
Stationary vehicles or vehicles moving
below 6 mph (10 km/h).
•
Pedestrians or objects in the roadway.
•
Oncoming vehicles in the same lane.
•
Severe weather conditions (see
blocked sensor section).
•
Debris build-up on the grille near the
headlamps (see blocked sensor
section).
•
Small distance to vehicle ahead.

If the front end of the vehicle is hit or
damaged, the radar sensing zone may be
altered causing missed or false collision
warnings. See your authorized dealer to
have your collision warning radar checked
for proper coverage and operation.
