• The windshield wipers are switched off when the ignition is
turned off. Activate the windshield wipers after the ignition is switched back on by moving the windshield wiper lever to any posi­
tion .
• Worn or dirty windshield wiper blades result in streaking. This
can affect the rain sensor * function. Check your windshield wiper
blades regularly.
• The rain sensor * is part of the interval wiping system. Turning off
the ignition will also deactivate the rain sensor*. To reactivate the sensor, switch off the interval wiping function, then switch it back
on again.
• The washer fluid nozzles of the windshield washer system are
heated at low temperatures when the ignition is on.
• When stopping temporarily, e.g. at a traffic light, the set speed of
the windshield wipers is automatically reduced by one speed .•
Service position
The windshield wiper blades are replaced in the service
position .

• On -changing the windshield wiper blades can only be done if
you bring the wiper arms to the service position
=> fig. 65. You will
also avoid paint damage to the hood when working on the wipers in
this position .
• Off -the windshield wipers are moved to their initial position
again.
0 Note
Never maneuver your vehicle with the front windshield wiper arms
raised since they will automatically be moved back to their basic
position above a speed of 3 mph (6 km/h) and can scratch the hood.
[ i J Tips
• You can also use the service position, for example, if you want to
protect the windshield from icing by using a cover . _,,

[ i J Tips
• If you sw itch off the automatic dimming function on the in side
mirror, autom ati c dimming of the outs ide mirror s will likewise be
di sabled.
• Check to make sure there are no objects preventing light from
reaching the inside mirror.
• Do not attach any sticke rs to the windshield in front of the light
sensor*, as this wou ld interfere with both the automatic operation
of the headlights and the automatic dimming of the inside mirror .
• Be aware that automatic dimming of the inside mirror can on ly
operate proper ly if the rear window sun blind* is retracted .•
Outsid e mirrors
The outside mirrors are electrically adjusted (power

Automatic recirculation
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode.
We recommend that you always keep automatic recirculati on ON to
prevent polluted outside air from entering the vehicle interior. .,_

___________________________________________________ W_ a_ r_m _ a_ n_d_ c_ o_ ld _ __.lffllll
If the a ir qu alit y se nsor located in the climate control system
detects polluted outside air, the sensor decides whether the air
pollution can be reduced by the factory -ins tal led pollutant filter or
whether it is necessary to switch to recirculation. With heavy
concentrations of pollutants, the climate control system is switched
automatically to rec irculation mode and the supply of outside air is
b locked. As soon as the concentration of pollutants in the outs ide
air drops , fresh air is supplied to the vehicle interior again.
In the event that the w indows fog up during automatic recirculation,
press the
[ liW ) button immediately.
Under certain operating conditions, automatic recirculation is
switched off automatically. When outside temperatures are below
about 50 °F
( + 10 °C), automatic recirculation is limited to
30 seconds . When outs ide temperatures are below about 30 °F (-

-Adaptive cruise control .._ _ ______,:,.._ _______________________________________ _
Adaptive cruise control
Speed and distance control system
Applies to vehicles: with adaptive cruise contro l
Description
The adaptive cruise control driver assistance program is
a combined speed and distance control system.
Fig . 122 Front
bumper: Position of
radar sensor
Any speed between about 20 mph (30 km/h) and about 95 mph
(150 km/h) can be set and held with the adaptive cruise control. The
system also regulates a pre-set distance from the vehicle ahead
within the limits of the system described.
Driving can be more relaxed, particularly on long trips on interstates
or on other highways that are generally straight.
How does it work?
You can operate the adaptive cruise control using the lever on the
steering wheel column:::::,
page 121, "How is the speed stored?" and
~ page 123, "How is the distance (time interval) set?".
Driver information
Important information is brought up in the speedometer and in the
instrument cluster display as the vehicle is being driven
=:> page 124, "Driver information".
What is important for you to know
The adaptive cruise control is set with system -specified limits, that
is, as a driver, you will have to adjust the speed and distance to the
vehicle ahead in some instances~
page 128, "Driver intervention
prompt" and~
page 130, "System limitations".
& WARNING
Improper use of the adaptive cruise control can cause collisions,
other accidents and serious personal injury.
• Never drive at speeds that are too high for traffic, road and
weather conditions.
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safely. The adaptive cruise control cannot brake the
vehicle safely when you follow another vehicle too closely. Always
remember that the adaptive cruise control has a braking power
that is only about 25% of the vehicle's maximum braking ability,
the automatic braking function cannot bring the vehicle to a stop.
• Never use adaptive cruise control on roads where you cannot
drive safely at a steady speed, including city, stop-and-go or heavy
traffic, on winding roads or when road conditions are poor (for
example, on ice, gravel , in fog, heavy rain or on wet roads that
increase the risk of hydroplaning).
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray. This can result in vehicles driving ahead being inade­
quately detected or, in some circumstances, not detected at all. If
necessary, take action yourself! ..,

_______________________________________________ A_ d_ a ---=- p_t_ i_v _e_ c_ r_ u_ i_ s _e_ c_ o_ n_t_ r _o _ l __ llll
& WARNING (continued)
• Always turn off adaptive cruise control when entering turn
lanes, highway exit lanes and construction zones or similar situa­
tions because the vehicle will automatically accelerate to the
stored speed.
• Never rest your foot on the accelerator pedal, especially when
the adaptive cruise control is being used because doing so will override the braking function and prevent the brakes from being
applied by the system when it detects a situation when the brakes
must be applied.
• Always remember that the adaptive cruise control has limits -
it does not react when you drive towards an obstacle or some­
thing else on or near the road that is not moving, such as vehicles stopped in a traffic jam, a stalled or disabled vehicle.
• Always remember that the adaptive cruise control cannot
detect a vehicle that is driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and
bicycles .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off.
• The Electronic Stabilization Program (ESP) and the Anti -Slip
Regulation (ASR) cannot be deactivated when the adaptive cruise
control is switched on. If the ESP and the Anti -Slip Regulation (ASR)
has been deactivated and you then switch on the adaptive cruise
control, the ESP function will also be activated automatically.
• Damage caused by accidents (e.g. if the vehicle is damaged
when parking) can affect the radar sensor settings. This can cause
the system to malfunction or switch off completely.
• The radar sensor cover is heated. In winter conditions, you
should still check before driving to make sure it is free of ice and
snow. If necessary, clean the area near the radar sensor carefully
=>
page 118, fig. 122.
Controls and equip ­
ment
• To ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, add -on parts) must not cover the area near the radar
sensor=>
page 118, fig. 122. The area near the radar sensor must
not be painted, either.
• For Declaration of Compliance to United States FCC and Industry
Canada regulations =>

How does adaptive cruise control work?
Vehicles traveling ahead are detected with the aid of a
radar sensor.

measurement range
A radar sensor is built into the front of the vehicle=> fig. 123, which
is subject to certain system limits=>
page 130. Stationary objects
are not taken into consideration. The system is intended to measure
the distance to reflective surfaces. The system responds after the
distance measurement has taken place. If a measurement is not
possible, the system does not respond.
Open road
When the road is clear, the adaptive cruise control works like cruise
control. It maintains a constant target speed specified by the driver .~
