Always keep the sensor clean. Carefully wipe the sensor
lens wi
th a soft cloth. Be cautious not to damage the sensor
lens.
Do not remove any screws from the sensor. Doing so could
cause
an ACC system malfunction or failure and require a
sensor realignment.
If the sensor or front end of the vehicle is damaged due to
a coll
ision, see your authorized dealer for service.
Do not attach or install any accessories near the sensor,
includ
ing transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc

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 reac

tivating it.

have the radar sensor realigned at your authorized dealer.
Installing a snow plow, front-end protector, an after-
