In AUTO position, the rain sensor
detects the amount of water on the
windscreen and automatically
regulates the frequency of the
windscreen wiper. If ignition is
switched off, automatic wiping mode
is deactivated. To activate automatic
wiping mode the next time ignition is
switched on, press the lever
downwards to position OFF and back
to AUTO .
For a single wipe when the
windscreen wiper is off, press the
lever downwards to position 1x.
Do not use if the windscreen is frozen. Switch off in car washes.

Telematics service
OnStar
OnStar is a personal connectivity and service assistant with integrated
Wi-Fi hotspot. The OnStar service is
available 24 hours a day, seven days
a week.
Notice
OnStar is not available for all
markets. For further information,
contact your workshop.
Notice
In order to be available and
operational, OnStar needs a valid
OnStar subscription, functioning
vehicle electrics, ignition on, mobile
service and GPS satellite link.
To activate the OnStar services and
set up an account, press Z and speak
with an advisor.
116LightingMotorway light
Activated automatically at a speed
above 71 mph. Illumination is
adapted to the higher speed driven on
motorways. If there is no oncoming
traffic, the visibility on the side of the
vehicle is increased. The visibility
range raises from 70 m to 140 m
allowing distant objects to be
recognised across the entire width of
the road.
Town light
Activated automatically at a speed up to approx. 34 mph and in situations
with exterior ambient light. The light is
wide and symmetrical. If the speed is
below 19 mph, the headlamps are
slightly swiveled to the outside to
allow an earlier recognition of
pedestrians and objects on each side
of the road. A special beam pattern is
designed to avoid glare for other road users.
Corner light
Activated at a speed of up to 25 mph
when turning off. The light consists of particular LEDs which illuminate the
direction of travel. These LEDs are
triggered depending on the steering
angle or the activation of the turn lights.
Adverse weather light
Controlled by wiper or rain sensor.
The wide light distribution – slightly
swiveled to the outside – enables
improved orientation at the edge of
the road. The intensity of the light in
the far distance is increased in order
to recognise objects and markings on
the right road side and obstacles on
the lane despite the weather
condition. By lowering the reflection
on wet roads the oncoming traffic is less dazzled. Adverse weather light is activated up to a speed to 43 mph.
Curve light
162Driving and operatingSwitching off the system
Press ß, the speed limiter mode is
deselected and the speed limit
indication extinguishes in the Driver
Information Centre.
Pressing m to activate cruise control
deactivates speed limiter.
The preset speed remains in the
memory when the ignition is switched
off.
Fault
In the event of a speed limiter fault,
the speed is cleared resulting in
flashing of the dashes.
The speed limiter may not operate
correctly if traffic signs do not comply
with the Vienna Convention on Road
Signs and Signals.
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 camerasensors 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
vehicle speed increases or decreases
to follow the vehicle ahead, but will
not exceed the set speed. It may
apply limited braking with activated
brake lights.
If the vehicle ahead accelerates or changes lane, the adaptive cruise
control progressively accelerates the
vehicle to return to the stored set
speed. If the driver operates a the turn lights to overtake a slower vehicle, the
adaptive cruise control allows the
vehicle to temporarily approach the
vehicle ahead to help passing it.
However, the set speed will never be
exceeded.The adaptive cruise control can store set speeds over 19 mph for manual
transmission. If the vehicle ahead is
moving too slowly and the selected
following distance cannot be
maintained anymore, a warning
chime is given and a message is
displayed in the Driver Information
Centre. The message prompts the
driver to take back control of the
vehicle. On vehicles with automatic
transmission, the system can brake
the vehicle until a full stop.9 Warning
The complete driver attention is
always required while driving with adaptive cruise control. The driver stays fully in control of the vehicle
because the brake pedal, the
accelerator pedal and the button
Ñ have priority over any adaptive
cruise control operation.
166Driving and operatingThe adaptive cruise control is
deactivated automatically when:
● The brake pedal is depressed.
● The vehicle accelerates above 112 mph or slows down below
19 mph.
● The electric parking brake is applied.
● The Traction Control system or Electronic Stability Control is
deactivated or operating.
● The selector lever of automatic transmissions is neither in D nor
in M.
● A fault is detected in the Electronic Stability Control or the
radar system.
Switching off the system
Press C, the adaptive cruise control
mode is disabled and the adaptive
cruise control indication extinguishes
in the Driver Information Centre.
Pressing ß to activate the speed
limiter deactivates adaptive cruise
control.Switching off the ignition deletes the
stored set speed.
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.System limits9Warning
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.
● The adaptive cruise control does ignore the oncoming traffic.
● The adaptive cruise control does not consider pedestrians and
animals for braking and driving
off.
● The adaptive cruise control considers stopped vehicles only
at low speed.
168Driving and operatingtake action and depress the brake
pedal, if you need to brake more
quickly.
Hill considerations9 Warning
Do not use the adaptive cruise
control on steep hill roads.
System performance on hills 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 you may have to brake to maintain or reduce your
speed.
Note that applying the brake
deactivates the system.
Radar unit
The radar unit is located in the middle of the front bumper.
9 Warning
The radar unit was aligned
carefully during manufacture.
Therefore, in the event of a front-
end impact, do not use the system. The front bumper may appear to
be intact, however the sensor
behind may be affected and react
incorrectly. After an accident,
consult a workshop to verify and
adjust the radar unit position.
Fault
In the event of a fault with the adaptive
cruise control, you are alerted by the
illumination of a warning light and the display of a message in the
instrument panel, accompanied by an
audible signal.
The adaptive cruise control may not
operate correctly if traffic signs do not comply with the Vienna Convention
on Road Signs and Signals.
Have the system checked by a dealer
or a qualified workshop.
As a safety measure, do not use the
system if the brake lights are faulty. Do not use the system if the front
bumper is damaged.
Forward collision alertThe forward collision alert may help to
avoid or reduce the harm caused by
front-end crashes.
The forward collision alert uses the
front camera in the windscreen and a radar unit located behind the front
bumper of the vehicle to detect a
vehicle directly ahead, in your path.
