Driver assistance systems
Introduction to the topic
The adaptive cruise control (ACC = Adaptive
Cruise Control) maintains a constant speed set
by you. When the vehicle approaches a vehicle
in front, ACC automatically adapts the speed to
the vehicle in front.
and thus maintains the distance set by you.

Disrupting regulation
—
Press the key or .
The speed remains saved.
Re-regulation
—
Press the key .
The limiter will be reactivated as soon as the speed
is lower than the stored speed.
Disconnect
—
Press and hold the key .
The speed limiter is switched off; the speed remains
stored (also after switching off the ignition).
Switching to cruise control (GRA) or
adaptive cruise
control
(ACC)
1.
Press the key .
2.
Select the desired system on the instrument
panel display.
The speed limiter is switched off.
Problems and solutions
Please note at the beginning of this chapter
on
page 138.
The regulation is automatically interrupted
- Abnormal operation. Switch off the speed limiter
and contact a specialist workshop.
For safety reasons, the speed limiter is only
completely disengaged when the driver takes his foot
off the accelerator at any time.
or disconnect the system manually.
Adaptive Cruise Control
(ACC)
How to find out if the vehicle has ACC
The vehicle is equipped with ACC if settings for this
system can be made in the infotainment system's
assistants menu.
Speed range
ACC regulates at speeds between approx. 30
km/h (20 mph) and 210 km/h (130 mph); at speeds
between 30 km/h (20 mph) and 210 km/h (130
mph) approx.
USA, UP TO APPROX. 150 KM/H (95 MPH). This
range may vary depending on the market.
Driving with ACC
You can override ACC control at any time. If you
brake, control is interrupted. If you accelerate,
control is interrupted for the duration of the
acceleration and then resumed.
Request to stop
If the automatic ACC deceleration is not
sufficient, ACC prompts you to brake further
by means of a message in the instrument
cluster. In addition, the red warning lamp
lights up and an acoustic warning sounds.
Brake immediately!
Radar sensor
ACC detects driving situations by means of a radar
sensor at the front of the vehicle. The range of this
sensor is approx. 120 m (approx. 400 ft).
Intelligent ACC technology cannot overcome the
limits imposed by the laws of physics and only
works within the limits of the system. Never
allow the increased comfort provided by this
technology to lead to safety risks. If used
carelessly or unintentionally, serious accidents
and injuries can occur. The system cannot replace
the driver's attention.
