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* – limitations

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.

Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if the driver is not looking straight ahead may make the visual warning signal in the windshield difficult to see. For this reason, always activate the audible warning signal.

Slippery driving conditions increase braking distance, which can reduce the system's capacity to avoid a collision. In these conditions, the ABS and stability systems provide the best possible braking effect while helping to maintain stability.

The visual warning signal may be temporarily disengaged in the event of high passenger compartment temperature due to strong sunlight, etc. If this occurs, the audible warning signal will be used, even if it has been deactivated in the menu system.

  • In certain situations, the system cannot provide warnings or warnings may be delayed if traffic conditions or other external factors make it impossible for the radar sensor or camera to detect a pedestrian, a cyclist or a vehicle ahead.
  • Warnings may not be provided if the distance to the vehicle ahead is short, or if movements of the steering wheel/brake pedal are great, such as during active driving.
  • The sensor system has a limited range for pedestrians/cyclists and provides warnings and braking effect most effectively at speeds up to 30 mph (50 km/h). For stationary or slow-moving vehicles, the system functions best if your vehicle’s speed is below approximately 45 mph (70 km/h).
  • Warnings for stationary or slow-moving vehicles may not be provided in dark conditions or in poor visibility.

The Pedestrian and Cyclist Detection with Full Auto Brake system uses the same radar sensors as Adaptive Cruise Control. For more information on the radar sensor and its limitations, see Adaptive Cruise Control – limitations.

If warnings are given too frequently, the warning distance can be reduced (see Collision warning – operation). This causes the system to provide later warnings, which decreases the total number of warnings provided.

  • The system is not activated at speeds under approx. 2 mph(4 km/h). Therefore, it will not brake your vehicle if you approach a vehicle ahead at very low speed, such as when parking.
  • The driver's actions always have highest priority and override the Pedestrian and Cyclist Detection with Full Auto Brake system. This means that the system will not intervene in situations where the driver is actively steering, braking or pressing the accelerator pedal, even if a collision is imminent.
  • When Auto-brake has prevented a collision with a stationary object, your vehicle will remain at a standstill for approx. 1.5 seconds. If your vehicle has been braked for a moving vehicle ahead, your vehicle's speed will be reduced to the same speed as that vehicle's.
