What it means

Shown as a car ahead with lines beneath it for the following distance, or a speedometer with a car, green when active and possibly white when on but not set, depending on the make. It means the system holds your set speed and slows down automatically to keep a safe gap to the car ahead. Amber, or an unavailable message, usually means the radar sensor or camera is blocked by dirt or dust.

Symptoms4

Indicator on while the car follows the vehicle ahead at a steady gap.
The number of lines under the car changes with the selected following distance.
A message saying the system is unavailable or the sensor is blocked.
The system cancels by itself in heavy rain or dust.

Possible causes6

System switched on by the driver and working normally.
Dirty radar sensor in the grille or badge, or dirty glass in front of the camera.
Bad weather such as heavy rain, dust or fog.
Radar misaligned after a minor front impact, or the camera needs calibration.
Other codes, such as a brake switch or ABS fault, that stop the system.
Failed radar sensor (less common).

How to diagnose4

Check the owner manual for the operating conditions and minimum speed.
Clean the front of the car where the radar sits and the glass in front of the camera, and remove any sticker or cover.
See whether the system returns once the weather clears.
At the workshop: read radar and camera codes, and check radar mounting angle and calibration, especially after front-end repairs.

How to fix5

Choose a suitable following distance and stay ready to brake.
Clean the sensors and remove anything blocking them.
Repair the brake switch or other faults that stop the system.
Recalibrate the radar or camera after any impact or front-end repair.
Replace the radar sensor if confirmed faulty, then road-test the system.

Frequently asked questions

Will the system bring the car to a full stop in traffic?

Some systems work down to a full stop and pull away again, while others switch off below a certain speed. Check the owner manual and always be ready to brake.

Why did the system stop after the front bumper was repaired?

The radar sensor usually needs precise remounting and calibration after front-end work; otherwise the system disables itself or works less accurately.
