Adaptive Cruise Control Light
This is usually informational. Address it at your convenience.
What the Adaptive Cruise Control Light Means
On the your car, this symbol means adaptive cruise is engaged, automatically adjusting speed to maintain a gap. Dirt, snow or a covered front sensor can make it temporarily unavailable.
Common Causes
- Front radar sensor blocked (dirt, snow, mud)
- Adaptive cruise engaged (normal)
- Radar calibration needed
- Sensor or module fault
- Poor weather limiting the radar
How to Fix It
- Clean the front radar area (grille/badge)
- Confirm the system is switched on
- Clear snow or ice from the sensor in winter
- Recalibrate the radar after front-end repairs
- Scan for driver-assist codes if it stays down
