• 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.
ACC Unavailable Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable, Vehicle System Error”, there may be a
temporary malfunction that limits ACC functionality.
Although the vehicle is still drivable under normal
conditions, ACC will be temporarily unavailable. If this
occurs, try activating ACC again later, following a key
cycle. If the problem persists, see your authorized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, it indicates
there is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the system
checked by an authorized dealer.
