One-touch wiping
- Move the lever to position @, when you want to wipe the
windshield
briefly.
Automatic wiper/washer
- Pull the lever to position © (toward the steering wheel)
and hold.
- Release the lever. The washer stops and the wipers keep
going for about four seconds. Depending on how long
the lever is held, different numbers of wash cycles are
performed.
Turning off the wipers
- Move the lever back to position @).
General information
The windshield wipers and the windshield washer system operate
only with the ignition on.
During a temporary stop, e .g. at a tra ffic signal, the set wipe speed
is automatically reduced by one stage.
The windshield washer nozzles are heated at low temperatures
when the ignition is on.
Removing water droplets
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 cycle while driving,
you have to pull the lever to position © again within 10 seconds
after this wipe cycle.
Water droplet removal is reactivated after the ignition is switched off and then on again.

Vehicle care I I irechnical data

Clear vision
Wint er p osition
To speed up de -icing of the windshie ld w ipers, they move to the
winter position when the ignition is switched off and at an outside
temperature below 39 °F (4 °C). In this position, the windshie ld
w ipers are in an area on the glass which is reached by the air vents
below the glass . It is a lso easier to remove snow and ice from the
windshield wipers in this position .
The wipers leave the winter position, when the ignition is switched on, if the wi ndshield wiper lever is ope rated or the active rain
sensor* reacts to moisture.
Rain sen sor*
The rain sensor operates only in the interval wiper position. When it
s tarts to rai n, the interval wiper m ode is ac tivated aut omatically.
If the windshield wiper lever is in the interval wipe position with the
igni tion switched off, the rain sensor is not activated unti l vehic le
speed is above 4 mph (6 km/h).
To reduce the sensitivity of the rain sensor, the switch@ must be
moved down . T o in crease the se nsitivity of the rain sens or, the
switch must be moved up .
The higher the sensi tiv ity se tting, the so oner the w indshield wipe rs
react to mo isture on the windsh ield. Increased sensitivity is
signa led by the windshie ld wipers making a single pass over the
windsh ield.
The rain sensor wiper intervals depend on the sensitivity setting as
we ll as veh icle speed . D uring b rie f stops, wiper m otio n will adjust in
relation to the amount of rain on the windshield .
& WARNING
• Wiper blades are cru cial for safe driving! Only when they are in
good condition are they able to clear the window s proper ly to
p rovide un comp romised visibil ity . Worn or damaged wiper blades
are a safety hazard =>
page 84, "In stalling new wiper blades "!
& WARNING (continued )
• The rain sensor* is only designed to assist and support the
driver . It remain s entirely the dr iver' s re spon sibility to monitor
out side weather conditions and to manually activate the wipers as
s oon a s rain or driz zle reduce s vi sibility through the wind sh ield .
0 Note
In freezing o r near freez ing conditions:
• Always check that the wiper blades are not frozen 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 wipe r motor.
• Do not use the wipers to clear a frosted window. Using the
wipers as a convenient ice scraper wi ll destroy the wiper blades .
• Before you ta ke you r vehicle to an automatic car was h, ma ke s ure
you have the windshield wiper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should sudden ly come on .
[ i ] Tips
• The rain senso r* is part of the interva l wiping syste m. Turning o ff
the ignition will also deactivate the rain sensor. To reactivate the
s en sor, switch o ff the interval wip ing funct ion, then sw itch it bac k
on again.
• Worn or dirty winds hield wiper b lades 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 o ff be fore go ing on a long trip. Look up=>

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 po lluted outside air, the sensor decides whether the air

the veh icle safely when you follow another vehicle too closely .
Always remember that the Adaptive Crui se Control has a braking
power th at is only about 30 % of the vehicle 's maximum braking
ability . The automatic braking function cannot bring the vehicle to
a sudden or emergen cy stop . Always be prepared to bra ke and
take evasive action to avoid collisions and other accident situa ­
tions .
• 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 ri sk of a rear -end crash .
• Never rest your foot on the accelerator pedal , especially when
the Adapt ive Cruise Control is being used . Pressure on the a cceler ­
ator will override the ACC braking function and prevent the brakes
from being appl ied when ACC detects a situation when the brakes
must be applied.
• Never use Adapt ive 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 r ain or on wet roads that increase the risk of
hydroplaning
I.
• 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 veh icles 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 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 .
Controls and equip ­
ment
[ i ] Tips
• For sa fety reasons , the sto red speed is de leted w he n th e ig nit ion

• The E lectronic Stabilization Program (ESP) and the Anti -Slip
R egu lation (ASR) cannot be deacti vated when the Adaptive Cruise
Co ntrol is sw itc hed on . If the ESP and the Anti-Slip Regula tion (AS R)
has been deactivated and you then switch on the Adaptive C rui se
Contro l, t he ESP func tion w ill also be act iva ted automat ica lly .
• Damage caused by accidents an d so me mino r co llisions can
affect t he radar sensor sett ings and cause the sys tem to ma lfun c­
tion or switch off completely.
• The radar sensor cover is heated. In winter conditions, you
should stil l check before driving to make sure it is free of ice and
s n ow. If necessary, clean the area near t he radar sensor carefully
~ page 15 2, fig. 159 .
• To ensure that the radar sensor is not blocked, foreign objects
(e .g. stickers, la rger l icense plate mount s, add -on pa rts) must not

How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of a
radar sens or.
Fig. 160 Bas ic p rin­
ci pl e diagra m: R adar
s en sor measur eme nt
ra nge
Adaptive Cruise Contro l uses a radar sensor in the fron t of the
vehic le=> fig. 160. The system has limitations=>
page 165. Things
t hat are not moving in your lane and in your direction of travel will
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
vehic le or something else up ahead.
Op en ro ad
When the road is clear, the Adaptive Cruise Contro l works like cruise
control. It maintains a constant target speed specified by the driver.
D rivi ng in t raffi c
If a slower vehicle driving ahead is detected, the Adaptive Cruise
Control dece lerates (within the limits of the system)=>
page 164,
"Driver intervention prompt" and=> page 165, "System l imitations"
to its speed and after adjusting, tries to maintain the set distance
from the vehicle ahead. The vehicle may temporarily drive slower
than the set speed wh ile adjusting=>
& in "Description" on
page 752 .
If the vehicle in front acce lerates, Adaptive Cruise Control a lso accel­
era tes up to the speed that you have set .
If the vehicle ahead s lows to a stop, ACC wi ll slow your vehicle down
and to a complete stop if this is possible within the system's limits
and capabil ities . ACC will not make an emergency stop. The text
message
ACC off : manu al c ontro l! appears in the instrument c luster
display . Once the veh ic le stops, you must depress the brake peda l
to prevent the vehicle from moving forward or "creeping" .
Depressing the brake pedal turns off ACC. When the veh ic le ahead
acce lerates you can reactivate ACC =>
page 157, as soon as your
vehic le has reached a speed of 1 mph (2 km/h).
S ituati ons re quir in g dri ver int erve ntion
In some situations you will have to use the footbrake to slow the
vehic le 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 164.
Passing anoth er v ehicl e
If you move into the passing lane and no vehicle is detected ahead,
the Adap tive Cruise Contro l accelerates to the speed you have set
and maintains it.
Ov erriding A CC
You can increase your speed at any time by stepping on the acceler ­
ator pedal. After you re lease the accelerator peda l, the system
adjusts back down to the speed you previously set.
Redu cin g stopping di stan ce
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum d istance, the brakes are automat ically
prepared for emergency braking by the driver. The brake pads are
moved very c lose to the brake discs without actually braking the
vehic le. This brake assis tant feature reacts more quickly to the
driver's braking, and also works when Adap tive Cruise Contro l is off.
The stopping distance is reduced as a result of this advance brake .,_
