Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stopped at a traffic light, driving will resume automatically if the vehicle is stopped for less than approx. 3 seconds. If it takes more than 3 seconds for the vehicle ahead to begin moving again, Adaptive Cruise Control will go into standby mode and the Auto-hold brake function will activate.

Note
ACC can keep the vehicle stationary for no more than 5 minutes – after that time the parking brake is applied and Adaptive Cruise Control is deactivated.
The parking brake must be released before Adaptive Cruise Control can be reactivated.
