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 ha zard
~ page 66, 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
i n position 0) . This helps to prevent unin ­
tentiona l switching on and damage to
the windshie ld w iper system .
@ Tips
-The windshield wipers are switched off
when the ignition is turned off. Activate
the w indshield w ipers after the ignit ion
i s switched back on by moving the wind­
sh ield wiper lever to any pos ition.
- Worn or dirty windshield wiper blades
cause smearing which can affect the op­
eration of the rain sensor . Check the con­
dit ion of yo ur windshield wipe r blades
regularly.
- The rain sensor is part of the interval
wiping system. Turning
off the ignition
will a lso deact ivate the rain sensor. To re­
activate the sensor, sw itch
off the inter­
va l w iping 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 2 73 for checking and fi lling 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 a ir recirculation ON to p revent polluted
outside air from enteri ng the veh icle inter ior.
If the
a ir qu ality sensor l ocated in the air con­
ditioning system detects polluted outs ide a ir,
the sensor dec ides whether the air pollut ion
can be reduced by the facto ry-installed pollu­
ta nt fi lter or whethe r it is necessary to switc h
to air recirc ulation. With heavy conce ntra ti ons
of pollu tants, the a ir condit ion ing system is
switched automatica lly to recirc ulation mode
and the supp ly 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 aga in.
In the event that the windows fog up during
automat ic air rec irculat ion, you must press
the® button immediately.
Under certa in ope rating cond itions, a utomatic
air recirculation is switched off automatica lly.
With outside temperatures be low about 50 °F
(+10 °C), automatic air rec irculat ion is limited
to 30 seconds. W it h outside temperatures be­
low about 30 °F ( -1 °C) a nd with the air condi­
tione r switched off, the a utomatic air recircu­
l ation is limited to 15 seconds.
Synchronization
One climate control setting for the driver and
front passenger seats .
With synchro nization active, the driver's set­
tings a re adopted for the passenger o r vice
versa . All the othe r setti ngs that were made
are t ransferred to t he other seat . This in­
cl udes all the cl ima te co ntro l settings, excep t
for the se at heating/ven tilat ion* .
If a different setting is selected at a
"synchron ized seat ", synchronization is can­
c e lled.

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 ility Contro l (ESC) and
the Anti-Slip Regulat ion (ASR) cannot be
deact ivated when the adaptive cruise control is switched on
. If the ESC and the
Anti-Slip Reg ulation (ASR) has been de­
act ivated and you then switch on the
adaptive cru ise contro l, the ESC function
w ill also be act ivated automatically.
- Damage caused by accidents and some m inor collisions can affect the radar sen­
sor settings and cause the system to
ma lf u nction 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 su re it is free of ice
and snow. If necessary, clean the a rea
nea r the radar sensor ca refully
¢ fig. 126.
- To ensure that the radar sensor is not
bloc ked, foreig n objects (e.g. s tickers,
larger license plate mount s, add -on
par ts) mus t not cover the area near the
radar sensor ¢
fig. 126 . The area near
the radar sensor must not be pa inted, ei­
ther.

Vehicles traveling ahead are detected with
the aid of a radar sensor .
Fig. 1 27 Bas ic pri ncip le d iag ram : Radar sensor meas ­

that must have a certain size. The system re­
sponds only after the distance measurement has been made. If a measurement is not pos­
sible, the system cannot respond and w ill not
react to a vehicle or someth ing else up ahead.
Open road
When the road is clear, the adaptive cruise
contro l works like cr uise control. It maintains
a constant target speed specified by the driv­
er.
Driving in traff ic
If a slowe r vehicle driving ahead is detec ted,
the adaptive cruise contro l decelerates (within
the limits of the system)

to its speed and after adjust ing,
tr ies to maintain the set distance from the ve­
h icle ahead. The vehicle may temporarily drive
slower than the set speed while adjust ing
¢ & in Description on page 113 .
If the vehicle in front accelerates, adaptive
cruise control also accelerates up to the speed
that you have set.
If the vehicle ahead slows to a stop, ACC will
slow your vehicle down and to a complete
stop 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 c ontrol!
appears in the instr ument
cluster display . Once the veh icle stops, you
must depress the brake pedal to prevent the
vehicle from moving forward or "creeping". Depressing the brake pedal turns
off ACC.
When the veh icle ahead accelerates you can
reactivate ACC
¢ page 118, as soon as your
ve hicle has reached a speed of 1 mph (2 km/
h) .
Situ ation s re quiring dri ver int ervention
In some s ituations you w ill have to use the
footbrake to s low the vehicle down in order to
keep 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
¢ page 124.
Ada pti ve crui se control 115
Passing another vehicle
If you move in to the passing lane and no ve hi­
cle is detected ahead, the adaptive 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 driver .
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 interfe 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 .
- On ly use floor mats that keep the area
around the peda ls free and that can be
securely fastened to the footwell .
