Adaptive Cruise Control (ACC)

surface, fog, stone chippings, heavy rain or
aquaplaning).
– Switch off ACC temporarily when driving on
turn-off lanes, highway exits or in areas with
roadworks. This will prevent the vehicle from ac-
celerating to the set speed in such situations.
– ACC does not brake automatically when the foot
is placed on the accelerator pedal. Placing the
foot on the accelerator pedal may override the
cruise and distance control.
– When approaching stationary vehicles, for ex-
ample at the end of a traffic jam, ACC only oper-
ates to a restricted extent.
– ACC does not react to people, animals, crossing
or oncoming objects.
– Reflective objects such as crash barriers or tun-
nel entrances, heavy rain or ice formation may
impair the functionality of the radar sensor. A
message indicating that ACC is not available ap-
pears on the instrument cluster.
Operating principle of Adaptive
Cruise Control (ACC)
No vehicles detected ahead – open road
Adaptive Cruise Control behaves like a speed control
system. The desired speed set is kept constant.
Vehicle detected in front – follow mode
If another vehicle that is traveling slower than the
selected speed is detected ahead in the same lane,
Adaptive Cruise Control automatically maintains a
set distance.
If the vehicle in front stops, Adaptive Cruise Control
slows the vehicle and brings it to a stop, provided
that this is possible within the system's control
parameters.
Adaptive Cruise Control actively keeps the vehicle in
a stationary position.
When the vehicle in front drives off, the automatic
speed and distance control can start again.
Override
The speed of the vehicle can be increased at any
time by pressing the accelerator pedal.
If the speed set by Adaptive Cruise Control vehicle is
exceeded by pressing on the accelerator pedal, the
Adaptive Cruise Control is deactivated.
A message indicating that ACC is in passive mode
appears on the instrument cluster. The desired
speed setting is retained.
After the accelerator pedal is released, Adaptive
Cruise Control maintains the desired speed on an
open road, or the appropriate distance when travel-
ing behind another vehicle.

Cruise Control (ACC) when active" on page 43.
