The function is active from a speed of around 80 km/h (around 50 mph).
Vehicles without Inside Overtaking Prevention System: When driving on a multi-lane road, cancel control if vehicles in the overtaking
lane are driving more slowly.
Limits of the sensors
ACC detects driving situations by means of the radar and ultrasound sensors in the front of the vehicle and the camera behind the
windscreen. The range of the radar sensor is up to approximately 120 m (around 400 ft).
WARNING
If you use ACC in driving situations that are outside the system limits, this could result in accidents and serious injuries as well as
violations of legal regulations.
● Observe the limits of the sensors (→ Sensors) and cancel control in the specified situations.
Objects that cannot be detected
ACC detects only vehicles that are moving in the same direction or stationary. The following are not detected:
—Persons.
—Animals.
—Crossing or oncoming vehicles.

Stationary vehicles
Stationary vehicle.
ACC reacts to stationary vehicles to a limited extent up to a speed of around 60 km/h (around 37 mph), provided a stationary vehicle is
detected and your own vehicle can be comfortably braked behind the stationary vehicle, subject to the system limits of the ACC. ACC
