General information
The winds hield wipers and the w indshield
washer system operate only with the ignition
on.
During a temporary stop , e.g . at a t raff ic sig­
na l, the set wipe speed is automatically re­
duced by one stage.
The winds hield washer no zzles a re heated at
l ow temperatures when the ignition is on .
Removing w ate r droplet s
About 5 seconds after the wash cycle is com­
plete, the wiper system performs a single au ­
tomatic wipe cycle to remove any water drop­
l ets that remain on the windshield whi le dr iv ­
ing.
If you would like to deactivate this delayed
wipe cycle wh ile driving, you have to pull the
l eve r to pos ition ® again within 10 seconds
after this wipe cy cle.
Water droplet removal is reactivated after the
ignit ion is switched off and then on again .
Winter position
To speed up de -icing of the w indshield w ipers,
t hey move to the winter posi tion when the ig­
n ition is switched off and at an outside tem­
perature below 39
°F (4 °(). In this posit ion ,
the w indshield wipers are in an area on the
g lass w hich is reached by the a ir vents below
the glass. It is also easier to remove snow and
ice from the wi ndshield wipers in this posi­
tion .
The wipe rs leave the w inte r position, when
the ign ition is swi tc h ed on, if the winds hield
wiper lever is operated or the active rain sen­
sor reacts to moistu re.
Rain sensor
The rain senso r operates on ly in the inte rva l
wiper position . When it sta rts to ra in , the in­
terval wipe r mode is activated automati ca lly.
If the windshie ld w iper lever is in the inte rval
wipe posit ion w ith the ign ition switched off, the ra
in sensor is not activated until ve hicle
sp eed is above 4 mph (6 km/h).
T o red uce the sensi tivi ty of the rain senso r,
the switch @ mus t be moved down . T o in­
crease the sensitivity of the rain sensor, the
switch must be moved up.
T he higher the sensit iv ity se tt ing , the sooner
the windshie ld wipers react to moist ure on
the windshie ld . I nc reased sensitivity is sig­
naled by the windshie ld wipers making a sin­
gle pass over the windshield.
T he rain sensor w iper intervals depend on the
sensitivity setting as well as vehicle speed.
D uring brief stops, wiper motio n will adj ust in
relat ion to the amount o f rain on the w ind­
shield .
A WARNING
-W iper blades are crucial for safe driving!
O nl y when they are i n good co ndit io n are
they able to clear the windows prope rly
to p rov ide uncompromised vis ib ility.
Wo rn o r damaged wipe r blades are a
safety hazard ~
page 67, Replacing
windshield wiper blades!
- T he rain sen so r is only designed to assist
a nd suppor t the driver.
It rem ains enti re­
ly the d river 's responsibility to monitor
outside weathe r conditions and to man­
ually activate the wipe rs as soon as rain
or driz zle reduces visibility through the
windshie ld.
(D Note
In freezing or near freezing conditions:
- Always check that the w iper b lades are
not frozen to the g lass before you turn
the wipe rs on . Loosen a wiper blade
wh ich is frozen in place before operating
the wipers to prevent damage to the
w iper blade or the wiper motor.
- Do not use the w ipers to clear a frosted
w indow. Us ing the wipers as a conven­
ient ice scrape r will destroy the wiper
blades .

-Prior to using a car wash, the windshield
wiper system must be switched
off (lever
in position 0). This helps to prevent unin­
tentional switching on and damage to
the windshield wiper system .
@ Tips
-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 wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades
cause smearing which can affect the op­
eration of the rain sensor. Check the con­
dition of 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 re­
activate the sensor, switch
off the inter­
val wiping function, then switch it back
on again.
- Make sure the washer fluid reservoir in
the engine compartment is topped
off
before going on a long trip. Look up
c:;, page 272 for checking and filling the
washer container.
Rear window wiper
The wiper lever is also used to operate the
rear window wiper and the automatic wiper/
washer function.

Automatic recirculation mode '
An air quality sensor detects increased con­
centrations of pollutants in the outside air
and automatically switches to recirculation
mode .
We recommend that you always keep auto ­
matic air recirculation ON to prevent polluted
outside air from entering the vehicle interior.
If the
air quality sensor located in the air con­
ditioning system detects polluted outside air,
the sensor decides whether the air pollution
can be reduced by the factory-installed pollu­
tant 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 recirculation, you must press
the® button immediately .
Under certain operating conditions, automatic
air recirculation is switched off automatically.
With outside temperatures below about SO °F
(+10 °(), automatic air recirculation is limited
to 30 seconds. With outside temperatures be­ low about 30 °F
( - 1 °() and with the air condi ­
tioner switched off, the automatic air recircu­ lation is limited to 15 seconds.
Synchronization
One climate control setting for the driver and
front passenger seats .
With synchronization active, the driver's set­
tings are adopted for the passenger or vice
versa. All the other settings that were made
are transferred to the other seat . This in­
cludes all the climate control settings, except
for the seat heating/ventilation* .
If a different setting is selected at a
"synchronized seat ", synchronization is can­
celled.

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 clos­
ing 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 peda l, especia lly when the adaptive
cruise control is be ing used. Pressu re on
the accelerator w ill override the ACC
braking function and prevent the brakes
from being applied when ACC detects a situation when the brakes must be ap­
plied.
- Never use adaptive cruise contro l when
you cannot drive safe ly at a steady
speed, including on city streets, on wind­
ing 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 .
T hese and sim ilar condit ions can prevent
vehicles up a head from being accurately
detected and in some cases they may not
be detected at al l. Do not use ACC when
the radar sensors cannot accurately de­
tect vehicles moving ahead of yo u in traf­
fic .
- Always turn off adaptive cruise contro l
when entering turn lanes , exit lanes and
construction zones or in similar situa­
t ions because the vehicle will automati­
cally accelerate to the stored speed when
the road ahead is clear.
- To prevent unintended operation, always
switch ACC off when it is not be ing used .
(D Tips
-For safety reasons, the stored speed is
deleted when the ignition is turned off .
- The E lectronic Stab ilizat ion Control (ESC)
i s automatically turned on when the
adaptive cruise control is turned on. You cannot switch the ESC into offroad mode
w hile the adaptive cruise contro l is
t u rned on
<=> page 225.
-Damage caused by accidents and some
mino r collisions can affect the radar sen­
sor settings and cause the system to
malf unction or switch off completely.
- The radar sensor cover is heated. In win ­
ter conditions, you should st ill check be­
fore dr iv ing to make sure it is free of ice
and snow. If necessary, clean the area
near the radar sensor carefully
<=> fig . 126 .
-To ensure that the radar sensor is not
blocked, foreign objects (e.g . stickers,
larger license plate mounts, add-on
parts) mus t not cove r the area near the

How does adaptive cruise control work?
Applies to vehicles: wi th adap tive c ruise contro l
Vehicles traveling ahead are detected with
the aid of a radar sensor.

sib le, the system cannot respond and wi ll not
react to a vehicle or someth ing else up ahead .
Open road
When the road is clear , the adaptive cru ise
control wo rks like cruise control.
It maintains
a constant target speed specified by the driv­
er.
Driving in traff ic

to its speed and after adjusting,
tr ies to maintain the set distance from the ve­
h icle ahead. The vehicle may temporarily drive
slower than the set speed while adjusting
¢ .&. in Description on page 113 .
If the vehicle in front accelerates, adaptive
cru ise control also accelerates up to the speed
t ha t you have set.
I f the vehicle ahead slows to a stop , ACC will
slow yo ur vehicle down and to a complete
s top if this is possible w ith in the system's lim­
its and capabilities. ACC will not make an
emergency stop . The text message
ACC off:
manual control! appears in the instrument
cluster display. Once the veh icle stops, you
must dep ress the brake pedal to prevent the
veh icle from mov ing forward or "creeping" .
Depressing the brake pedal turns
off ACC.
When the vehicle ahead accelerates yo u can
reactivate ACC
¢ page 118, as soon as your
vehicle has reached a speed of 1 mph (2 km/
h) .
Situat ion s requiring dri ver int ervention
In some situations you wi ll have to use the
footbrake to s low the vehicle down in order to
k eep a safe distance from vehicle in front of
you or to avo id a rear -end coll is ion. In this sit­
uation, a symbol appears and a warning tone
sounds ¢

Adapti ve crui se control 115
Passing another vehicle
If you move into the passing lane and no ve hi­
cle is detected ahead , the adapt ive cr uise con­
trol acce le rates to the speed you have set and
maintains it.
Overr iding ACC
You can in cr ease yo ur speed at a ny time by
stepping on the accelera tor ped al. A fter you
release the accelerator peda l, the system ad­
justs back down to the speed you prev ious ly
set .
Reducing stopp ing distance
If the radar sensor detects that the d istance
to the vehicle a head is less than de fined m ini­
mum distance, the brakes are automatically
prepared fo r emergency braking by the d river .
The brake pads are moved very close to the brake d iscs without actually braking the vehi­
cle. This brake assistant feature reacts more
quick ly to the dr ive r's brak ing, and also works
when adapt ive cruise control is
off . The stop­
ping distance is reduced as a result of th is ad­
vance brake p reparation . Th is fun ction does
not perform any emergency b rak ing mane u­
vers by itse lf; the dr iver mus t always apply the
brakes.
A WARNING
If ACC initiates a braking maneuver, the brake pedal w ill be retracted. Inter ference
with the brake peda l can prevent ACC from
slowing the veh icle down and cause a
crash and serious personal injury.
- Never put anything in the driver's foot­
well or let anyth ing fall into it. An object
in the driver's footwe ll can inte rfe re with
the peda ls and prevent the acce le rator
from being used to override ACC or pre­
vent ACC from being switched
off when
the brake pedal is depressed and also
prevent the vehicle from being slowed
down or stopped .
- Onl y use floor mats that keep the area
aroun d the peda ls free and that can be
securely fastened to the footwell .

appears :
- The ACC sensor is d irty . The ACC system is
not react ing, or is not reacting correctly, to
moving vehicles up ahead in your lane of
t ravel.
- There may be very light traffic on and there
is nothing that marks the side of the road
