When cornering
When driving into or driving out of long corners, it could be that a vehicle is
travelling in the adjacent lane and is scanned by the radar
host vehicle is then controlled according to this vehicle.
Narrow vehicles or vehicles travelling side by side
A narrow or offset vehicle driving can only be recognized by the ACC if this is
located in the scanning range of the radar
Other vehicles changing lanes
Vehicles that change onto the lane with a small distance
be detected by ACC in good time.
Stationary vehicles
The ACC does not detect stationary objects! When a vehicle detected by the
ACC turns or sheers off and there is a stationary vehicle in front of this vehicle,
» Fig. 310
- the ACC does not respond to the stationary vehicle.
Vehicles with special load or special body parts
Other vehicles with a load or with body parts protruding from the sides, back
or top of the vehicle contour may not be detected by the ACC.
Overtaking and towing
Read and observe
on page 247 first.
When overtaking
When your vehicle is being controlled at a speed that is lower than the set
speed and the turn signal is operated, ACC assesses this situation as meaning
that the driver wishes to overtake. The ACC automatically accelerates the ve-
hicle, thereby reducing the proximity to a vehicle ahead.
If your vehicle changes to the overtaking lane and no vehicle is detected
ahead, ACC accelerates until the set speed is reached and then keeps it con-
stant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
Towing a trailer
When towing, or if another accessory is connected to the trailer socket, ACC
control is set with a lower rate. The manner of driving should therefore be
adapted to this limitation.

Malfunctions
Read and observe
on page 247 first.
If, for some unknown reason, ACC is not available, the warning light appears
in the display of the instrument cluster and an appropriate message is shown.
Sensor covered / dirty
If the sensor cover or the sensor is dirty or covered, a message appears on the
instrument cluster display stating there is no sensor view. Clean the sensor
cover or remove the obstacles
» Fig. 266
If there is no sensor view in the winter, the snow on the sensor under the cov-
er could be the reason. The ACC is functional again after the snow melts away
from the sensor.
ACC not available
If the ACC is currently unavailable, a message concerning the unavailability ap-
pears. Stop the vehicle, switch off the engine and then start it again. If ACC
continues to be unavailable, seek the assistance of a specialist garage.
ACC fault
With an ACC fault, an error message appears. Seek help from a specialist ga-
rage.
