Driving with ACC
You can override the ACC system at any time. The regulation function is canceled when you apply the brakes. When you
accelerate, the regulation function is paused while accelerating and then resumed with the speed set.
Driver intervention request
If automatic deceleration by the ACC is not sufficient or the system limits are reached, the ACC will prompt you – with a
message in the instrument cluster – to also apply the brakes. The red warning light will also turn on and a warning tone will
sound. Take over steering and be ready to brake.
WARNING
ACC is not a replacement for the driver's attention and works only within the system limitations. ACC cannot detect all
driving situations and may not react, or may react with a delay, or may react in a way that is not desired. If you are
careless, there is a risk of accidents, serious injuries and death.
Always stay attentive and do not rely solely on the system. The driver is always responsible for control of the
vehicle.
Observe the system limitations ⇒ ACC system limitations.
Always adapt your speed and distance to vehicles driving ahead based on the visual, weather, road, and traffic
conditions.
Take over steering immediately if a driver intervention prompt appears in the instrument cluster display or the
deceleration by ACC is not sufficient.
Apply the brakes if the vehicle continues to roll unintentionally, e.g. after a driver intervention prompt.
