signal is automatically deactivated.
For three flashes, e.g. when changing lanes, press the lever until resistance
is felt and then release.
When a trailer is connected, turn
signal flashes six times when
pressing the lever until resistance is
felt and then releasing.
Move the lever to the resistance point
and hold for longer indication.
Switch the turn signal off manually by moving the lever to its original
position.
Front fog lights
Operated by pressing >.
Light switch in position AUTO:
switching on front fog lights will switch headlights on automatically.
138LightingRear fog light
Operated by pressing r.
Light switch in position AUTO:
switching on rear fog light will switch
headlights on automatically.
Light switch in position 8: rear fog
light can only be switched on with
front fog lights.
The vehicle rear fog light is
deactivated when towing a trailer or a
plug is connected with the socket, e.
g. when a bicycle carrier is used.
Parking lights
When the vehicle is parked, the
parking lights on one side can be
activated:
1. Switch off ignition.
2. Move turn signal lever all the way up (right parking lights) or down
(left parking lights).
Confirmed by a signal and the
corresponding turn signal control
indicator.
Reversing lights
The reversing light comes on when
the ignition is on and reverse gear is
selected.
Misted light covers
The inside of the light housing may
mist up briefly in poor, wet and cold weather conditions, in heavy rain or
after washing. The mist disappears
quickly by itself; to help switch on the
headlights.

180Driving and operatingSwitching off
Press C to switch off adaptive cruise
control. The control indicator m and
C in the Driver Information Centre
extinguish. The stored speed is
deleted.
Switching off the ignition also
switches off adaptive cruise control
and deletes the stored speed.
Driver's attention ● Use adaptive cruise control carefully on bends or mountain
roads, as it can lose the vehicle
ahead and require 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 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 completely suppresses thevisibility. In case of sensor
blockage, clean the sensor
cover.
System limits ● The system's automatic brake force does not permit hard
braking and the braking level
may not be sufficient to avoid a
collision.
● After a sudden lane change, the system needs a certain time to
detect the next preceding
vehicle. So if a new vehicle is
detected, the system may
accelerate instead of braking.
● Adaptive cruise control does ignore the oncoming traffic.
● Adaptive cruise control does not brake for pedestrians, animals,very slow speed driving or
stopped vehicles.
● Don't use adaptive cruise control when towing a trailer.Bends
The adaptive cruise control calculates
a predicted path based on the
centrifugal force. This predicted path
considers the current bend
characteristic, but cannot consider a
future bend change. The system may lose the current vehicle ahead or
consider a vehicle which is not in the
actual lane. This can happen when
entering or exiting a bend or if the
bend gets stronger or weaker. If it no
longer detects any vehicle ahead,
then control indicator A will
extinguish.
If the centrifugal force is too high in a bend, the system slows down the vehicle slightly. This braking level is
not designed to avoid spinning off the bend. The driver is responsible for
reducing the selected speed before
Driving and operating181entering a bend and in general to
adapt the speed to the road type and
to existing speed limits.
Motorways
On motorways, adapt the set speed
to the situation and the weather.
Always consider that adaptive cruise
control has a limited visibility range, a
limited braking level and a certain
reaction time to verify if a vehicle is in
the driving path or not. Adaptive
cruise control may not be able to
brake the vehicle in time to avoid a
collision with a much slower vehicle or after a lane change. This is
particularly true if driving fast or if the
visibility is reduced due to weather
conditions.
While entering or exiting a motorway,
adaptive cruise control may lose the
vehicle ahead and accelerate up to
the set speed. For this reason,
decrease the set speed before the
exit or before the entry.
Vehicle path changes
If another vehicle enters your driving
path, adaptive cruise control will first
consider the vehicle when it is
completely in your path. Be ready to
take action and depress the brake
pedal, if you need to brake more
quickly.
Hill and trailer considerations
System performance on hills and
when towing a trailer depends on
vehicle speed, vehicle load, traffic
conditions and the road gradient. It
may not detect a vehicle in your path
while driving on hills. On steep hills,
you may have to use the accelerator
pedal to maintain your vehicle speed.
When going downhill, especially
when towing a trailer, you may have
to brake to maintain or reduce your
speed.
Note that applying the brake
deactivates the system. It is not
recommended to use adaptive cruise
control on steep hills especially when towing a trailer.
