Limits of the ACC
When not to use the ACC
ACC is not suitable for use in the following driving situations due to the system limitations. To cancel control:
Driving in heavy rain, snow or heavy spray. Driving through road works, tunnels or toll stations. Driving on winding roads, e.g. mountain roads. Driving in multi- storey car parks. Driving on roads with embedded metal objects, e.g. railway tracks. Driving on roads with loose chippings. After external collision on components in the area of the radar sensor, e.g. after a rear- end collision.
WARNING
If you use ACC in the above situations, this could result in accidents and serious injuries as well as violations of legal regulations.
Delayed response
If the radar sensor is exposed to environmental conditions that impair sensor functioning, the system may detect this only after a certain delay. For this reason, any restrictions to functions may be displayed only after a delay at the start of the journey and when driving.
Objects that cannot be detected
ACC detects only vehicles that are moving in the same direction or stationary. The following are not detected:
People. Animals. Lateral or oncoming vehicles. Other stationary obstacles.
Stationary vehicles
Stationary vehicle
ACC reacts to stationary vehicles to a limited extent up to a speed of around 60~\mathrm{km / h} , 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 does not perform emergency braking.
The reaction to stationary vehicles depends on the vehicle equipment.
Bends
Driving through bends
The radar sensor always measures straight ahead. For this reason, vehicles may be incorrectly detected or vehicles driving ahead not detected in tight bends.
Vehicles outside the sensor range
Small vehicle
Vehicle changes lane
CC may not react or may react with a delay or with an unwanted response in the following driving situations:
Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g. motorbikes. Vehicles that change into your lane directly in front of your vehicle. Vehicles with bodies or attachments that project beyond the vehicle.
