Using the Pre-Collision Assist
System
WARNING
The Pre-Collision Assist 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 adjust the warning system's
sensitivity through your information
display. See General Information (page
96).
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
96).

The surface of the radar sensor cover is
clean but the message remains in the
display
Heavy rain, spray, snow or fog in the air

Blocked Sensors
E145632
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 pre-collision assist
system will not work. Possible causes for
the blocked sensor message and corrective
actions are listed below.
Clean the radar sensor cover or remove the
obstruction
Wait a short time. The radar may take
several minutes to reset after you remove
the obstruction
