216 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
• Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or
malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the "Adaptive
Cruise Control Off" state and will resume function by
simply reactivating it.
NOTE:
• If the "Clean Radar Sensor In Front Of Vehicle"
message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at your
authorized dealer.
• Installing a snow plow, front-end protector, an after-
market grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit
ACC operation.
Removing ACC Sensor For Off-Roading
NOTE: When off-roading, it may be advisable to re-
move the ACC sensor. The sensor is located behind the
front lower grille in the center of the vehicle. After
removing the lower fascia, you may remove the lower
sensor and bracket assembly.
To remove the sensor follow these instructions:
1. Unplug the connector by depressing the two tabs on
the connector and pulling it out. Do not pull by the
wiring or use any tools to remove the connector.
2. Remove the wiring christmas tree attachment from the
back of the bracket.
3. Remove the two M6 fasteners that connect the bracket
to the bumper.
