If a stationary vehicle is hidden behind a vehicle that has been detected by the adaptive cruise
control and this vehicle turns off the road or changes lane, the ACC will not react to the stationary
vehicle ⇒ Fig. 144.
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 ⇒ Fig. 143.
Vehicles outside the sensor range
•Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g.
motorbikes ⇒ Fig. 143.
•Vehicles that change into your lane directly in front of your vehicle ⇒ Fig. 144.
•Vehicles with bodies or attachments that project beyond the vehicle.
