E156131
When your vehicle rapidly approaches
another vehicle, a red warning light flashes
and a tone sounds.
The brake support system assists you in
reducing any collision speed by
pre-charging the brakes. If the risk of
collision continues to increases after the
audio-visual warning, the brake support
prepares the brake system for rapid
braking. The system does not
automatically activate the brakes, but if
the brake pedal is pressed even lightly, the
brakes apply full stopping power.
Using the Collision Warning System
WARNING
The collision warning system's brake
support reduces collision speed only
if you brake your vehicle before any
collision. As in any typical braking situation,
you must press your brake pedal.
You can use your information display
control to adjust the collision warning
system's sensitivity or to turn the system
On or Off. Your vehicle will remember
these settings across key cycles. You may
change the collision warning system
sensitivity to any one of three possible
settings. See General Information (page
103).

Note: It is recommended that you turn the
collision warning system off if a snow plow
or similar object is installed in such a way
that it may block the radar sensor. Your
vehicle will remember the selected setting
across key cycles.
Note: When possible, the manufacturer
recommends using the highest sensitivity
setting. If warnings are too frequent, you can
reduce your system's sensitivity. Reduced
sensitivity causes fewer and later system
warnings. See General Information (page
103).
Blocked Sensors
E183741
If a blocked sensor message appears in the
information display, dirt, water, or an object
is blocking the sensor. The sensor is
located behind a cover near the driver side
of the lower grille. If anything blocks the
sensor, your vehicle cannot see through
the sensor, and the collision warning
system will not work. Possible causes for
the blocked sensor message and corrective
actions are listed below.
