ACC: currently not available. No sensor
v
i
sion
ACC and Front Assist: currently not
available. No sensor vision
This message will be displayed to the driver if
the radar sensor's vision is impaired due, for
example, to leaves, snow, heavy fog or dirt.
Clean the sensor.
ACC: currently not available. Gradient too
steep
The maximum road slope has been excee-
ded, hence safe ACC operation cannot be
guaranteed. The ACC cannot be switched on.
ACC: only available in D, S or M
Select the D/S or M position on the selector
lever.
ACC: parking brake applied
The ACC is deactivated if the parking brake is
applied. The ACC is available once again after
the parking brake is released.
ACC: currently not available. Intervention
of stability control
The message for the driver is displayed when
the electronic stability control (ESC) inter-
venes. In this case, the ACC is automatically
switched off.
ACC: Take action!
The message for the driver is displayed if,
when the vehicle starts up on a hill with a
mild slope, the vehicle rolls back even al-
though the ACC is activated. Apply the brake
to stop the vehicle from moving/colliding
with another vehicle.
ACC: speed limit
The message for the driver is displayed if, in
vehicles with manual gearbox, the current
speed is too low for the ACC mode.
The speed to be stored must be at least 30
km/h. The cruise control system switches off
if the speed falls below 20 km/h.
ACC: available as of the 2nd gear
The ACC is operational as of the 2nd gear
(manual gearbox).
ACC: engine speed
The message for the driver is displayed if,
when the AAC accelerates or brakes, the driv-
er does not shift up or down a gear in time,
which means exceeding or not reaching the
permissible engine speed. The AAC switches
itself off. A buzzer warning is heard.
ACC: clutch pressed
Vehicles with a manual gearbox: pressing the
clutch pedal for longer abandons control
mode.
Three white dots appear if a setting made
with the control lever cannot be performed.
For example, if when the vehicle is stationary
the ACC cannot be activated because the
driver is not wearing the seat belt.
Door open
Vehicles with automatic gearbox: the ACC
cannot be activated with the vehicle station-
ary and the door open.
Deactivating the Adaptive Cruise
Control ACC temporarily in certain
situations
In the following situations the Adaptive
Cruise Control (ACC) should be deactivated
due to the system's limitations ››› :
●
When changing lanes, on tight bends and
roundabouts, in acceleration and decelera-
tion lanes on motorways or in sections with
road works to prevent involuntary accelera-
tion to reach the programmed speed.
●
When going through a tunnel, as operation
could be affected.
●
On roads with several lanes, when other ve-
hicles are driving more slowly in the overtak-
ing lane. In this case, slower vehicles will be
overtaken on the right.
