Adaptive Cruise Control (ACC)
Functionality
ACC 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
The ACC does not respond to crossing or oncoming
objects.
ACC is intended primarily for use on motorways.
pACC (predictive cruise control)
pACC is an enhancement of the ACC system.
pACC adjusts the speed according to recognized
speed limits and the route, e.g. turns, intersections or
roundabouts.
The system uses the following sources to evaluate
the situation.
▶
Navigation data.
▶
Dynamic Road Sign Display.
▶
Sensors, radars and cameras.
WARNING
pACC does not respond to railway crossings.
Speed range
Depending on the equipment, ACC allows a speed
setting in the range of 30-210 km/h.
If control is started at a speed of less than 30 km/h,
the speed is automatically increased to 30 km/h or
controlled 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
The vehicle can be decelerated to a stop using the
ACC and start moving again. Control is disconnected
in case of longer holding periods.
To resume control:
›
Depress the accelerator pedal.
Or:
›
Put the lever into position
.
Or:
›
Applies to vehicles with a system for detection of
hand on the steering wheel: grab the steering
wheel again.
The control is interrupted when the brake pedal is
depressed.
Overtaking
If your vehicle changes to the fast lane and no vehi-
cle is detected in front, ACC accelerates up to the
set speed.
