The Collision avoidance assistance function consists of three subfunctions:
- Steering assistance upon risk of run-off
 - Steering assistance upon risk of head-on collision
 - Steering assistance upon risk of rear-end collision*
 
After automatic engagement, the driver display indicates that this has occurred via a text message:
- Collision avoidance assistance Automatic intervention
 
Note
It is always the driver who decides how much the car should steer – the car can never take command.
