In order to give you the best possible support we need to know which car you have, since functionalities, services and features may differ between models. By selecting a car model your search will include information from the owner's manual for that specific model. We do several model year updates every year. Each new update comes with a specific model year code that you will find at the back of your Owner’s Manual. The code is written as ATXXXX, for example AT1446.

Collision warning – troubleshooting

Pedestrian and Cyclist Detection with Full Auto Brake is designed to assist the driver if there is a risk of a collision with a pedestrian, a cyclist, a vehicle ahead that is at a standstill or one that is moving in the same direction as your vehicle.

Fault tracing and actions

If the message Windscreen Sensors blocked is displayed, this means that the camera is obscured and cannot detect pedestrians, cyclists, vehicles or road marker lines in front of the vehicle.

This, in turn, means that Pedestrian and Cyclist Detection with Full Auto Brake, Driver Alert Control, Lane Departure Warning or Lane Keeping Aid will not have full functionality.

The table lists possible causes for this message being displayed, and suitable actions.

Cause

Action

Clean or clear the section of the windshield in front of the camera.

Fog, heavy rain or snow is interfering with the function of the camera.

No action possible. Heavy precipitation may affect the function of the camera.

The surface of the windshield is clean but the message remains in the display.

Wait a short time. It may take several minutes for the camera to register visibility.

The surface between the inside of the windshield and the camera is dirty.
