windshield
briefly.
Automatic wiper /washer
- Pull the lever to position © (toward the steeri ng w heel)
and hold .
- Re lease the lever. The washer stop s and t he wip ers keep
going for about four seconds . Depending on how long the
lever is held, d ifferent numbers of was h cyc les are
performed.
Turning off the wipers
- Move the lever back to positio n@ .
Gen eral information
The windshield wipers and the windshield washer system operate
only with the ign it ion on .
Dur ing a temporary stop, e.g. at a traff ic signa l, the set wipe speed is
automatica lly red uced by one stage.
Th e windshie ld washer noz zles a re heated at low tempe ratures when
the ignition is on .
Removing water droplets
About 5 seconds afte r the was h cycle is complete, the wipe r system
performs a single automat ic wipe cycle to remove any water droplets
that remain on the windshie ld w hile driving.
If you would like to deact ivate this delayed wipe cy cle w hile d riving,
you have to pull the lever to position ® aga in w it hi n 10 seconds after
this wipe cycle.
Water droplet removal is react ivated after the ign ition is sw itched off
and then on again.

W int er pos ition
T o speed up de -icing of the windshield wipers, they move to the
w inter position when the ig nitio n is switched off and at an outs ide
temperature below 39 °F (4 °C). In this position, the windshield
wipers a re in an a rea on the g lass which is reached by the air vents
below the g lass. It is also easier to remove snow and ice from the
windshield wipers in this position.
The w ipers leave the w inter pos it ion, when the ign it ion is switched
on, if the w indshield wipe r lever is operate d or the act ive rain sensor*
reacts to moisture .
Rain sensor*
The rain sensor operates on ly in the interval wiper position. When it
sta rts to rai n, the in terv al wiper mode is a ctivated a utomat ic al ly.
If the w indshield wipe r leve r is in the inte rval wipe position with the
ignition switched off, the rain sensor is not act ivated until vehicle
speed is above 4 mph (6 km/h) .
To reduce the sens itivity of the rain sensor, the switch © must be
moved down. To i ncrease t he se nsitivi ty of the ra in se nso r, the sw itch
must be moved up.
Th e higher the sensitivity setting, the sooner the windshie ld wipers
react to mo isture on the windshie ld . Increased sensit ivity is signa led
by the windshie ld wipers making a s ingle pass over the windshie ld.
Th e rain se nsor wiper inte rvals de pend on the se nsi tivity se tt ing as
well as veh icle speed . During br ief stops, w iper motion will ad just in

Automatic recirculation mode
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 air recirculation ON
to prevent polluted outside air from entering the vehicle inter io r.
If the
air quality sensor located in the air cond it ion ing system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the factory-installed pollutant filter or whether it is
necessary to switch to air recirculation. With heavy concentrations of
pollutants, the a ir cond it ion ing system is switched automat ically to
recircu lation mode and the supply of outside air is b locked . As soon
as the concentration of pollutants in the outside air drops , fresh air is
supplied to the vehicle interior again. In the event that the windows fog up during automatic air recircula­
tion, you must press the® button immediately.
Under certa in operating conditions, automatic a ir recirculation is
switched off automatically. With outside temperatures below about
SO °F
(+10 °C), automatic air recirculation is lim ited to 30 seconds.
With outside temperatures below about
30 °F (-1 °() and with the air
conditioner switched off, the automatic air recirculation is limited to
15 seconds. •

page 147 , "Sy stem limi ta tio ns".
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury.
• Always remember that the Adaptive Cruise Control has limits -
it will not slow the vehicle down or maintain the set distance when
you drive towards an obstacle or something 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 bicy­
cles.
• Never drive at speeds that are too fast for traffic, road and
weather conditions.
• Never follow a vehicle so closely that you cannot stop your
vehicle safely. The Adaptive Cruise Control cannot slow or brake _.,

& WARNING (continued)
the veh icle s afely when you follow another vehicle too closely.
Alway s rem ember that the Adaptive Cruise Control has a braking
powe r that is only about 30 % of the vehicle's maximum braking
ability. The automatic braking function cannot bring th e ve hicle to
a sudden or emergency stop . Always be prepared to brake and take
evasive action to avoid collisions and other accident situations .
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to
slow your vehicle safely. If closing speed is too h igh, you must
apply the brake s your self to reduce the ri sk of a rear-end cra sh .
• Never rest your foot on the accelerator pedal , especially when
the Adaptive Crui se Control is being used. Pressure on the acceler­
ator will overr ide the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brake s
must be applied .
• Never u se Adaptive Cruise Control when you cannot drive safely
at a steady speed, including on city streets , 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
vi sion can be redu ced by rain, snow and
heavy road spray. These and similar conditions can prevent vehi­
cle s up ahead from being accurately detected and in some cases
they may not be detected at all. Do not use ACC when the radar
sensors cannot accurately detect vehicles mo ving ahead of you in
traffic .
• Always turn off Adaptive Crui se Control when entering turn
lanes, exit lanes and con struction zones or in similar situat ions
because the vehicle will automatically accelerate to the stored
speed when the road ahead i s clear .
• To prevent unintended operation , always switch ACC off when
it is not being used .

How does Adaptive Cruise Control work?
Vehicles traveling ahead ore detected with the aid of a
radar sensor.
Fig. 129 Basic prin­
ciple diagram: Radar
sensor measurement
range
Adaptive Cruise Control uses a radar sensor in the front of the vehicle
=>
page 136, fig. 129 . The system has limitations=> page 147.
Things that are not moving in your lane and in your direction of travel
w ill not be detected. The sensor measures the distance to reflective
surfaces that must have a certain size. The system responds only
after the distance measurement has been made . If a measurement is
not possible, the system cannot respond and will not react to a
vehicle or someth ing else up ahead.
Open road
When the road is clear, the Adaptive Cru ise Control works like cruise
control. It maintains a constant target speed specified by the driver .
Driving in traffic
If a slower veh icle driv ing ahead is detected, the Adaptive Cruise
Control decelerates (within the limits of the system)=>
page 146,
"Driver intervention prompt" and => page 147, "System limitations"
to its speed and after adjusting, tries to ma inta in the set distance
from the vehicle ahead. The vehicle may temporarily drive slower
than the set speed whi le adjusting=>
& in "Descr iption" on
page 134.
If the vehicle in front accelerates, Adaptive Cruise Control also accel­
erates up to the speed that you have set.
If the vehicle ahead slows to a stop, ACC w ill slow your vehicle down
and to a complete stop if this is possible within the system's limits
and capabilities . ACC will not make an emergency stop. The text
message
ACC off: manual control! appears in the instrument cluster
display . Once the vehicle stops, you must depress the brake pedal to
prevent the veh icle from moving forward or "creeping" . Depressing
the brake pedal turns off ACC. When the vehicle ahead accelerates
you can reactivate ACC =>
page 139, as soon as your vehicle has
reached a speed of 1 mph (2 km/h) .
Situations requiring driver intervention
In some situations you will have to use the footbrake to slow the
vehicle down in order to keep a safe distance from vehicle in front of
you or to avoid a rear-end collision. In this situation, a symbol
appears and a warning tone sounds=>
page 146.
Passing another vehicle
If you move into the passing lane and no vehicle is detected ahead,
the Adaptive Cruise Control accelerates to the speed you have set and
maintains it.
Overriding ACC
You can increase your speed at any time by stepping on the acceler ­
ator pedal. After you release the accelerator pedal, the system
adjusts back down to the speed you previously set.
Reduc ing stopping distance
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum distance, the brakes are automatically
prepared for emergency braking by the drive r. The brake pads are
moved very close to the brake discs withou t actually bra king the
vehicle. This brake assistant feature reacts more quickly to the driver's braking, and also works when Adaptive Cruise Control is off.
The stopping d istance is reduced as a result of this advance brake .,_
