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

The radar sensor and the camera work together to detect a pedestrian, a cyclist, stationary vehicles and vehicles that are moving in the same direction as your vehicle. If there is a risk of collision with a vehicle, a cyclist or a pedestrian, the driver is alerted by a flashing red warning light and an audible warning signal. The system is active at speeds above 3 mph (4 km/h).

Brake Support

If the risk of collision continues to increase after the collision warning has been given, Brake Support is activated. Brake Support prepares the brake system to react quickly, and the brakes are applied slightly. This may be experienced as a light tug.

If the brakes are applied quickly, full braking effect will be provided. Brake Support also increases brake force if the system determines that the driver has not applied adequate pressure on the brake pedal.


If a collision is imminent and the driver has not applied the brakes or begun to steer around the vehicle, pedestrian or a cyclist, the auto-brake function is activated without the driver pressing the brake pedal. Full brake force is applied to help reduce the vehicle’s speed when the collision occurs or limited brake force is applied if this is sufficient to avoid the collision.

The auto-brake and brake support functions are always on and cannot be turned off.
