Continuing cruise control
An interrupted cruise control can be continued
by calling up the stored speed.
Make sure that the difference between current
speed and stored speed is not too large before
calling up the stored speed. Otherwise, uninten‐
tional braking or accelerating may occur.
Press the button with the system inter‐
rupted.
Cruise control is continued with the stored val‐
ues.
In the following cases, the stored speed value is
deleted and cannot be called up again:
▷ When the system is switched off.
▷ When drive-ready state is switched off.

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 acceler‐
ates 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 maintained. The
speed is adjusted as far as the given situation al‐
lows.
General information
A radar sensor is located in the front bumper and
a camera on the interior mirror to detect vehicles
driving ahead of you.
Depending on the vehicle setting, the cruise
control settings may change under certain condi‐
tions. For instance, acceleration can change de‐
pending on the driving mode.
The distance can be adjusted in several steps.
For safety reasons, it depends on the respective
speed.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief period,
the system is able to detect this within the given
system limits.
