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* – operation

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.

Settings are made by pressing MY CAR on the center console control panel and using the menus displayed.

Activating/deactivating both warning signals

To switch the system's audible and visual signals on or off at the same time, press MY CAR on the center console control panel and go to SettingsCar settingsDriver support systemsCollision Warning. If Pedestrian and Cyclist Detection with Full Auto Brake is on, the system will perform a self-test each time the engine is started by briefly illuminating the warning light. See My Car – introduction for a description of the menu system.

When the engine is switched on, the system setting that was being used when it was switched off will be the default setting.

The auto-brake and pedestrian/cyclist detection features are always on, even if the audible and visual warning signals have been deactivated.

Activating/deactivating the audible warning signal only

The audible warning signal can be activated/deactivated by pressing MY CAR on the center console control panel and going to SettingsCar settingsDriver support systemsWarning sound if risk of collision.

Setting a warning distance

This setting determines the distance at which the visual and audible warnings are triggered. Select Long, Normal or Short by pressing MY CAR on the center console control panel and going to SettingsCar settingsDriver support systemsCollision WarningWarning distance.

The warning distance determines the level of sensitivity used by the system. The warning distance Long provides an earlier warning. Begin by using Long and if the system gives too many warnings, try changing to Normal.

  • The setting Short should only be used in situations where traffic is light and moving at low speeds.
  • Pedestrian and Cyclist Detection with Full Auto Brake alerts the driver to the risk of a collision but this function cannot reduce the driver’s reaction time.
  • For the system to be as effective as possible, it is recommended that Distance Alert be set to 4 or 5, see Distance Alert – operation.
  • When Adaptive Cruise Control is used, the warning light and signal will be used by that function, even if the warnings provided by Pedestrian and Cyclist Detection with Full Auto Brake have been deactivated by the driver.
  • In situations where traffic is moving at considerably different speeds, or if the vehicle ahead brakes suddenly, warnings may be considered to be late, even if the setting Long has been selected.

Checking settings

The current system settings can be checked by pressing MY CAR on the center console control panel and going to SettingsCar settingsDriver support systemsCollision Warning.
