Adaptive Cruise Control Not Available
Several conditions exist which can cause the system to deactivate or
prevent the system from activating when requested. These conditions
include:
• a blocked sensor
• high brake temperature
• a failure in the system or a related system.
Blocked Sensor
WARNING: Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly
when ACC is activated because the brakes are electronically controlled.
Failing to do so may result in loss of vehicle control, which could result
in serious injury.
WARNING: Do not use tires sizes other than those
recommended because this can affect the normal operation of
ACC. Failing to do so may result in a loss of vehicle control, which
could result in serious injury.
