Adaptive cruise control warning
This light means the adaptive cruise control system (which automatically maintains following distance) is unavailable or has detected a fault.

Possible systems involved
Possible systems are not yet verified.
Common triggers
The forward radar or camera sensor obstructed or misaligned
Heavy rain, snow, or fog reducing sensor reliability below the system's operating threshold
A sensor or control-module fault
Check this before driving
Clean any sensor areas that may be obstructed
Use standard (non-adaptive) cruise control or manual speed control instead
Have it scanned if the fault persists in good weather with clean sensors
Frequently asked questions
