Adaptive cruise control
The adaptive cruise control is an
enhancement to the conventional
cruise control with the additional
feature of maintaining a certain
following distance to the vehicle
ahead. It uses radar and camera
sensors to detect the vehicles ahead. If no vehicle is detected in the driving
path, the adaptive cruise control will
behave like a conventional cruise
control.
The adaptive cruise control
automatically decelerates the vehicle
when approaching a slower moving
vehicle. It then adjusts the vehicle
speed to follow the vehicle ahead at
the selected following distance. The
Driving and operating165Adaptive cruise control onvehicles with automatic
transmission
For vehicles with automatic
transmission, adaptive cruise control allows to maintain the selected
distance behind a stopping vehicle
until a complete stop is reached.
If the system has stopped your
vehicle behind another vehicle, then
the set speed is replaced by a green
control indicator .. This symbol
notifies, that the vehicle is hold
automatically in stop position.
If the stopped vehicle ahead was
stopped for a longer time and then
begins to move forward, the green
illuminated vehicle ahead control
indicator . will flash and a warning
chime will sound as a reminder to check traffic before resuming.
When the vehicle ahead drives away,
press the accelerator pedal until
30 km/h and then move the thumb
wheel to SET- or RES+ to resume
adaptive cruise control. If the vehicle
stays stopped for more than
5 minutes or if the driver's door isopened and the driver's seat belt is
unfastened, then the electric parking
brake is applied automatically to hold
the vehicle. Control indicator m will
illuminate. To release electric parking brake, press the accelerator pedal.
Electric parking brake 3 151.9 Warning
When the system is deactivated or
cancelled, the vehicle will no
longer be held at a stop and can
start moving. Be always prepared
to manually apply the brake to hold the vehicle stationary.
Do not leave the vehicle while it is
being held at a stop by adaptive
cruise control. Always move
selector lever to park position P
and switch off the ignition before
leaving the vehicle.
Setting the following distance
When adaptive cruise control detects
a slower moving vehicle in the driving path, it will adjust the vehicle speed tomaintain the following distance
selected by the driver.
The following distance can be set to
close (1 bar), normal (2 bars) or far (3 bars).
If the engine is running and the
adaptive cruise control is enabled
(grey), you can modify the following
distance setting:
Press Ö, the current setting is shown
in the Driver Information Centre.
Press Ö again to change the following
distance: The new setting is

Driver's attention ● Use the adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and needs time to detect it again.
● Do not use the system on slippery roads as it can create
rapid changes in tyre traction
(wheel spinning), so that you
could lose control of the vehicle.
● Do not use the adaptive cruise control during rain, snow or
heavy dirt, as the radar sensor
can be covered by a water film,
dust, ice or snow. This reduces or
suppresses completely the
visibility. In case of sensor
blockage, clean the sensor
cover.
● Do not use the system when the spare wheel is in use.
