Adaptive Cruise Control (ACC)
Functionality
Control
ACC maintains the set speed. When your vehicle ap-
proaches the vehicle in front, ACC will automatically
start to maintain the set distance to this vehicle.
Maintaining the set speed and the distance will here-
inafter be referred to as Control.
WARNING
ACC does not respond to stationary objects or to
crossing or oncoming objects.
ACC is intended primarily for use on motorways.
Speed range
Depending on the equipment, ACC allows a speed
setting in the range of 30-160 or 30-210 km/h.
If control is started at a speed of less than 30 km/h
on vehicles with an automatic transmission, the
speed is automatically increased to 30 km/h or con-
trolled according to the speed of the vehicle ahead.
Distance level
The distance to the vehicle ahead can be adjusted to
five different levels.
WARNING
Maintain a minimum distance in accordance with
▶
the country-specific legal regulations.
Automatic stop and start
A vehicle with an automatic transmission can be de-
celerated to a stop using the ACC and start moving
again. Control is disconnected in case of longer hold-
ing periods.

To resume control, depress the accelerator pedal

Overtaking
If your vehicle changes to the fast lane and no vehi-
cle is detected in front, ACC accelerates up to the
set speed.
