Vehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and
systems, the applicable laws and regulations
must be observed.
Active Cruise Control with
Stop&Go function, ACC
Concept
Using this system, a desired speed and a dis‐
tance to a vehicle ahead can be adjusted using
the buttons on the steering wheel.
The system maintains the desired speed on
clear roads. For this purpose, the vehicle ac‐
celerates or brakes automatically.
If a vehicle is driving ahead of you, the system
adjusts the speed of your vehicle so that the
set distance to the vehicle ahead is main‐
tained. The speed is adjusted as far as the
given situation allows.
The distance can be adjusted in several steps.
For safety reasons, it depends on the respec‐
tive speed.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pe‐
riod, the system is able to detect this within the
given system limits.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Safety information
WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re‐
spective situations.◀
WARNING
An unsecured vehicle can begin to move
and possibly roll away. There is a risk of an ac‐
cident. Before exiting, secure the vehicle
against rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
Set the parking brake.
On uphill grades or on a downhill slope,
turn the front wheels in the direction of the
curb.
On uphill grades or on a downhill slope,
also secure the vehicle, e.g., with a wheel
chock.◀
WARNING
The desired speed can be incorrectly ad‐
justed or called up by mistake. There is a risk
of an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐
tively intervene in the respective situations.◀
WARNING
Risk of accident due to too high speed
differences to other vehicles, e.g., in the fol‐
lowing situations:
When fast approaching a slowly moving
vehicle.
Suddenly swerving vehicle onto the own
lane.
