Gen era l inform ati on
The windshield wipers and the windshield washer system operate
only with the ignition on.
During a temporary stop, e.g. at a traffic signa l, the set wipe speed
is aut omatically reduced by one stage .
The windshield washer nozzles are heated at low temperatures
when the ignition is on .
Removing vv ater drop let s
About 5 seconds after the wash cycle is complete, the wiper system
performs a single automatic wipe cycle to remove any water drop ­
lets that remain on the windshield .
If you would like to deactivate this delayed wipe cyc le whi le dr iving,
you have to pull the lever to position © again within 10 seconds
af ter this w ipe cyc le .
Water droplet removal is reactivated after the ignition is switched off and then on again .
Rain se nsor
The ra in sensor operates on ly in the interval wiper position . When it
starts to rain, the interval wiper mode is activated automatically .
I f the windshie ld wiper lever is in the interval wipe position with the
ign ition sw itched off, the rain sensor is not activated unt il veh ic le
speed is above 4 mph (6 km/h) .
T o reduce the sens itivi ty of the rain sensor, the swi tch
© must be
moved down. To increase the sensitivity of the rain sensor, the
sw itc h must be moved up .
T he higher the sensitivity sett ing, the sooner the windshield wipers
react to moisture on the windshie ld. Increased sensitivity is
signa led by the windshie ld w ipers making a si ng le pass over the
windshield.
T he rain sensor wiper interva ls depend on the sens itivity setting as
we ll as vehicle speed. During brief stops, wiper motion will adjust in
r elation to the amount of rain on the windshield .
& WARNING
• Wiper blades are crucial for safe driving! Only when they are in
good cond ition are they able to clear the windo ws properly to
provide uncompromised visibility . Worn or d am aged wiper blades
are a safet y hazard ::::> page
74 , "I nst alli ng new wiper blades "!
• The rain sensor is only designed to a ssist and support the
dri ver . It remai ns entirel y the dr iver's respon sibil ity to monitor
out side weather conditions and to manually activate the wiper s as
so on a s rain or dri zzle reduce s vis ibility through the wind sh ield.
• The wind shield must not be treated with water -repellent mate ­
rials . The y can incre as e g la re under poor visibility condition s su ch
as wetness , darkne ss, or when th e sun is low on t he horizon. In
addition , they can cause the wind shield wiper s to ch att er.
0 Note
In freezing or near freezing conditions :

• Always check that the wiper blades are not fro zen to the glass
before you turn the wipers on. Loosen a wiper blade which is frozen
in place before operating the wipers to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wipers to clea r a frosted window . Using the
wipers as a convenient ice scraper will destroy the wiper blades.
• Before you take your v ehicl e to an automatic car wash, make sure
you have the windshield wiper system switched off (lever in position
Ol, otherwise the windshield wiper sys tem could get damaged in the
car wash if it should suddenly come on.
[ i] Tips
• 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.
• Worn or dirty windshield wiper blades cause smearing which
can affect the operation of the rain sensor. Check the condition of
your windshield wiper blades regularly.
• Make sure the washer fluid reservoir in the engine compartment
is topped off before going on a long trip. Look up~
page 316for
checking and filling the washer container .•

lever for longer than one second.
The washer jets extend forward out of the front bumper driven by
water pressure to spray the front headlights with water.
Controls and equip ­
ment
Clear vision
You should inspect the headlights regularly (for example when refu­
eling) and clean off any solid dirt or insects from the lenses.
To ensure the system works properly in winter , keep the washer jets
free of snow and
remove any ice using a de -icing spray .•
Service position
The wiper blades can only be changed in the service posi­
tion.
Fig. 66 MMI display :
Windshield wipers
At below freezing outside temperatures, make sure first
that the wiper blades are not frozen to the windshield.
- Press the [CAR] function button.
- Select Windshield wipers . The Windshield wipers menu
appears ~ fig. 66.
- Select Service position on to turn the service position on
or
off to return the windshield w iper to its orig inal posi­
tion .
You must only attempt to change the wiper blades when the s ervice
position is activated. This way, when you are working on the wind ­
shield wipers , you can
avoid damaging the paint on the engine
hood.

& WARNING
Broken glass of automatic dimming mirror can cause electrolyte
fluid leakage. Electrolyte fluid can irritate skin, eyes, and respira­
tory system .
• Repeated or prolonged exposure to electrolyte can cause irrita­
tion to the respiratory system, especially among people with
asthma or other respiratory conditions. Get fresh air immediately
by leaving the vehicle or, if that is not possible, open windows and
doors all the way.
• If electrolyte gets into the eyes, flush them thoroughly with
large amounts of clean water for at least 15 minutes; medical
attention is recommended.
• If electrolyte contacts skin, flush affected area with clean water
for at least 15 minutes and then wash affected area with soap and
water; medical attention is recommended. Thoroughly wash
affected clothing and shoes before reuse.
• If swallowed and person is conscious, rinse mouth with water
for at least 15 minutes. Do not induce vomiting unless instructed
to do so by medical professional. Get medical attention immedi­
ately.

Liquid electrolyte leaked from a broken mirror glass will damage any
plastic surfaces it comes in contact with . Clean up spilled electrolyte
immediately with clear water and a sponge .
[ i ] Tips
• If you switch off the automatic dimming function on the inside
mirror, automatic dimming of the outside mirrors will likewise be
disabled.
• Check to make sure there are no objects preventing light from
reaching the inside mirror. •
Do not attach any stickers to the windshield in front of the light
sensor, as this would interfere with the automatic operation of the
headlights and the automatic dimming of the inside mirror.
• Be aware that automatic dimming of the inside mirror can only
operate properly if the rear window sun blind * is retracted .•

ECON
The ECON mode helps to save fuel.
The air conditioning is turned off in ECON mode. "ECON" means
"Economy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or dehumidified.
If the vehicle interior becomes too hot or if the windows fog up,
ECON mode should be turned off. As soon as the
jAUTO I button in
the air conditioning controls is pressed, the system automatically leaves the ECON mode, and the air conditioning compressor is
turned on again. •
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 interior.
If the
air quality sensor located in the air conditioning 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 air conditioning system is
switched automatically to recirculation mode and the supply of
outside air is blocked. 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 certain operating conditions, automatic air recirculation is
switched off automatically. With outside temperatures below about
+ 10
°C, automatic air recirculation is limited to 30 seconds. With
outside temperatures below about -1 °C and in the ECON mode,
automatic air recirculation is limited to 15 seconds. •
Synchronization
One climate control setting for the passenger's and
driver's seats.
After Synchronization is set to on, all of the subsequent climate
control settings (except for seat heating*) for the driver are trans ­
ferred to the front passenger.
Synchronization is canceled when settings are adjusted on the front passenger's side. •
Center air vent
The temperature of the air leaving the center vents can be
changed to differ from the temperature setting.

Center air vent
The air flow coming from the center vents can be adjusted to be
colder or warmer than the selected set temperature.

& WARNING (continued)
• 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 high , you must
apply the brakes yourself to reduce the risk of a rear -end crash.
• Never rest your foot on the accelerator pedal, especially when
the Adaptive Cruise Control is being used. Pressure on the acceler ­
ator will override the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brakes must be applied .
• Never use 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
vision can be reduced by rain, snow and
heavy road spray. These and similar conditions can prevent vehi ­
cles 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 moving ahead of you in
traffic.
• Always turn off Adaptive Cruise Control when entering turn
lanes, exit lanes and construction zones or in similar situations
because the vehicle will automatically accelerate to the stored
speed when the road ahead is clear.
• To prevent unintended operation, always switch ACC off when
it is not being used.
[ 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 (ASRI has been deactivated and you then switch on the
Adaptive Cruise
Control, the ESP function will also be activated automatically.
• Damage caused by accidents and some minor collisions can
affect the radar sensor settings and cause the system to malfunc­
tion 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 127, fig. 123.
• To ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, larger license plate mounts, add -on parts) must not
cover the area near the radar sensor=>
page 127, fig. 123. The area
near the radar sensor must not be painted, either.

How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of a
radar sensor.

Adaptive Cruise Control uses a radar sensor in the front of the
vehicle=> fig. 124. Th e system has limitations=>

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 wil l not react to a
vehicle or something else up ahead.
O pen ro ad
When the road is clear, the Adaptive Cruise Control works like cruise
control. It main tains a constant target speed specified by the driver.
D riv in g in tr affic
If a slower vehic le driving ahead is detected, the Adaptive Cruise
Control dece lerates (within the limits of the system)::::;,
page 138,
"Driver intervention prompt" and::::;, page 140, "System limitations"
to its speed and after adjusting, tries to maintain the set distance
from the vehicle ahead . The vehicle may temporarily drive s lower
than the set speed while adjusting::::;,
& in "Description" on
page 127.
If the vehicle in front accelerates, Adaptive Cruise Control a lso acce l­
erates up to the speed that you have set.
Sit uation s re qui ring d rive r int erve ntion
In some situations you will have to use the footbrake to s low the
vehicle down in order to keep a safe distance from vehic le in front
of you or to avoid a rear -end collision. In this situation, a symbol
appears and a warning tone sounds::::;,
page 138.
P assing anoth er veh icle
If you move into the pass ing lane and no vehicle is detected ahead,
the Adaptive Cruise Control accelerates to the speed you have set
and ma intains it.
O ve rridin g ACC
You can increase your speed at any time by stepping on the acceler­
ator pedal. After you re lease the acce lerator pedal, the system
adjusts back down to the speed you previously set.
Controls and equip ­
ment R
edu cin g s topping di sta nce
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum distance, the brakes are automatical ly
prepared for emergency braking by the driver . The brake pads are
moved very c lose to the brake discs without actual ly braking the
vehic le. This brake assistant feature reacts more quick ly to the
driver's braking, and also works when Adaptive Cruise Control is off.
The stopping distance is reduced as a result of this advance brake
preparation. This function does not perform any emergency brak ing
maneuvers by itself; the driver must always app ly the brakes.
& WARNING
• Never r ely on the d istan ce control feature of ACC alone t o

[ i ] Tip s
Please note that the amount of acceleration the Adaptive Cruise
Contro l uses depends on the Distance setting selected . DISTA NCE 1
gives you acceleration that is dynamic and sporty . D ISTANCE 4, on
t he o ther hand, gives more moderate acce leration. For more infor ­
mation about the time intervals::::;,
page 133, "How is the distance
(time interval) set?" .
• Please note that if the Adaptive Cruise Control has begun braking
t he vehicle and the driver chooses to brake the vehicle additional ly,
the brakes may feel "hard". This is simply due to the pressure build ­
up of the initial braking .
• Adaptive Cruise Control is switched off after pressing the foot­
brake . The speed saved up this point can be resumed. To resume the
saved speed, release the brake pedal and pu ll the control lever _.,

tained. The ACC system is not switched off, and increased attention
to the traffic situation is absolutely necessary. The following may be
reasons why the message
ACC functionality limited appears:
• The ACC sensor is dirty . The ACC system is not reacting, or is not
reacting correctly, to moving vehicles up ahead in your lane of
travel.
• There may be very light traffic on and there is nothing that marks
the side of the road (for example, guard rails, traffic signs, trees). As
soon as a moving vehicle up ahead is detected again, ACC becomes
active again and the message disappears .
The ACC sensor is located in the area under the front license plate.
If the ACC sensor is dirty or blocked, clean the area to restore system
operation.
ACC not available
The text message ACC not available appears, for example, if the
temperature of the brakes is excessive . Adaptive Cruise Control is
temporarily not available. A warning tone sounds as a reminder.
ACC not available!
The text message ACC not available! appears in the event of a
malfunction. Adaptive Cruise Control is turned off. A warning tone
sounds as a reminder. Have the system inspected by a qualified
dealership .
ACC sensor blocked !
The text message ACC sensor blocked ! appears when the ACC
System can no longer accurately detect vehicles moving up ahead
in your lane of travel. Adaptive Cruise Control is turned off. A
warning tone a lso sounds as a reminder.
To decide whether it is necessary to switch off the ACC (ACC sensor blocked
!) or if it is only a temporary condition (ACC Functionally
limited), the system will also takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC sensor is dirty or blocked (e.g. leaves, snow) . The
ACC sensor is located in the area under the front license plate .
If the ACC sensor is dirty or blocked, clean the area to restore system
operation.
EPB activation
Th e text message EPB activation appears if emergency braking was
manual ly initiated with the Electromechanical Parking Brake (EPB).
The Adaptive Cruise Con trol is turned off . This is accompanied by a
warning tone.
