Gen eral information
The windshie ld wipers and the windshield washer system operate
only with the ign it ion on .
During a temporary stop, e.g. at a traff ic signal, the set w ipe speed is
automatically reduced by one stage.
The windsh ie ld washer nozzles are heated at low temperatures when
the ignition is on.
Removing w ate r dr oplet s
About S seconds after the wash cycle is complete, the wiper system
performs a single automatic wipe cycle to remove any water droplets
that remain on the windsh ield .
If you would l ike to deact ivate this delayed wipe cycle whi le driving,
you have to pull the lever to position ® again within 10 seconds after
t his wipe cycle .
Water droplet removal is reactivated after the ignition is switched off
and then on again.

Rain sensor
The rain sensor operates on ly in the interval wiper position . When it
starts to rain, the interval wiper mode is activated automat ically .
I f the windshield wiper lever is in the interval wipe position with the
ign ition switched off, the rain sensor is not activated until vehicle
speed is above 4 mph (6 km/h) .
To reduce the sensitivity of the rain sensor, the switch @ must be
moved down . To increase the sensit ivity of the rain sensor, the switch
must be moved up.
The higher the sensitiv ity sett ing, the sooner the windsh ield wipers
react to mo isture on the windshie ld. Increased sensitivity is signa led
by the windshield w ipers making a single pass over the windshie ld.
T he rain sensor wiper intervals depend on the sensitivity setting as
we ll as vehicle speed. During brief stops, wiper motion will adjust in
relation to the amount of rain on the windshield .
& WARNING
• Wiper blades are crucial for safe driving! Only when they are in
good condition are they able to clear the windows properly to
provide uncompromised visibility. Worn or damaged wiper blades
are a safety hazard =>
page 68, "Replacing windshield wiper
blades"!
• The rain sensor is only designed to assist and support the
driver. It remains entirely the driver 's responsibility to monitor
outside weather conditions and to manually activate the wipers as
soon as rain or drizzle reduces visibility through the windshield.
• The windshield must not be treated with water-repellent
materials. They can increase glare under poor visibility conditions
such as wetness, darkness, or when the sun is low on the horizon.
In addition, they can cause the w indshield wipers to chatter.
0 Note
In freez ing or near freezing conditions:
Controls and equip ­
ment Safety first

•
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 operat ing the w ipers to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wipers to clear a frosted window . Us ing the wipers
as a convenient ice scraper will destroy the wiper blades.
• Before you take your vehicle to an automatic car wash, make sure
you have the windshield wipe r system switched off (lever in position
0), otherw ise the windshield wiper system could get damaged in the
car wash if it shou ld suddenly come on.
(I] Tips
• Worn or dirty windshield wiper blades cause smearing which can
affect the operation of the rain sensor . Check the condit ion of your
windshield wiper b lades regularly.
• The rain sensor is part of the interval wiping system . Turn ing off
the ignition will a lso deactivate the rain sensor. To reactivate the
sensor, switch off the interval wip ing function, then switch it back on
again.
• The w indshield wipers are switched off when the ignition is turned
off . Activate the windsh ie ld wipers after the ignition is switched back
on by mov ing the w indshield wiper lever to any pos it ion.
• Make sure the washer fl uid reservoir in the engine compar tment is
topped off before going on a long trip . Look up::::>
page 294 for
checking and filling the washer conta iner. •

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 qu alit y sen sor 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 whethe r it is
necessary to switch to air recirculation. With heavy concentrations of
poll utants, the a ir condit ion ing system is switched automatically to
recirculation mode and the supply of outside air is blocked . As soon
as the concen tration of pollutants in the o utside air drops, fresh air is
supplied to the vehicle in terior again .
In the event that the windows fog up during automatic air recircula­
tion, you must press the® button immed iately.
Under certain operating conditions, automatic a ir recirculation is
switched off automatically. With o utside temperatures below about
SO °F ( +10 °(), automatic air recirculation is limited to 30 seconds .
With outside temperatures below about 30 °F (-1 °C) and the cooling
system is switched off, the automatic air recirculation is limited to 15
seconds. •

Adaptive Cruise Control has technical limitations that you must k now,
so p lease read this sectio n carefully, un de rstand how t he sys tem
wor ks and use it pro perly at all times.
How does it work?
You ca n operate the Adaptive Cruise Control using the lever on the
st eerin g wheel column=>

What is important for you to know
The Adaptive Cru ise Contro l is set with system-spec ified limits; that
is, as a driver, you will have to a djus t the s pee d and dis tan ce to t he
vehicle ahead in some in stances =>
page 130, "Driver intervention
promp t" and =>
page 131, "System lim itat ions".
ln. WARNING
Improper use of the Adaptive Cruise Control can cau se collisions,
other accidents and serious personal injury .
• Always remember that the Adaptive Cruise Contro l 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 mo ving, such as vehicles stopped in a traffic jam, a
stalled or disabled vehicle .
• Always remember that the Adaptive C rui se 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 .
• The Adaptive Cruise Control cannot slow or brake the vehicle
safely when you follow another vehicle too closely . Always
remember that the Adaptive Cruise Control has a braking powe r
that is only about 30% of the vehicle 's maximum braking ability .
Always be prepared to b rake and ta ke e vasive action to a void colli-
sions and other accident situations . .,

& WARNING (conti nu ed )
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not b e able to
slow your vehicle safely.
If closing speed is too high , you must
appl y the brake s yourself to r educe the risk of a rear-end crash.
• Never re st your foot on the accelerator pedal , especially when
the Adaptive Crui se Control is being used . Pre ssure on the acceler ­
ator will o verride the ACC braking fun ction 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 incre ase the risk of hydroplaning ).
• The radar sensor's
vision can be reduced by rain, snow and
heavy road spray. These and simila r conditions can p revent vehi­
cles up ahead from b eing accurately detect ed and in some cases
they may not be detected at all. Do not use ACC when the rad ar
sen sors cannot ac curately detect vehicle s moving ah ead of you in
traff ic.
• Alway s turn off Adaptive Cruise Control when ente ring turn
lanes, exit lanes and construction zones or in similar situations
becaus e the vehicle will automatic ally a ccelerate 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 tu rned off.
• The Electronic Stabilization Program (ESP) and the Anti-Slip Regu­
la tion (ASR) cannot be dea ct iv a te d w he n t he A dapt ive Cruise Co ntr ol

ES P fu nction w ill als o be a ct iv a te d a utom atically.
• Damage caused by accidents and some minor collisions can affect
t he rad ar sensor settings and c ause the system to malfunction o r
switch off completely .
• Th e radar s ensor cover is heate d. In w in ter cond itions, you sho uld

Reducing stopping distance
If the radar sensor de
tects tha t the dis tance to the vehi cle ahea d is
less than defined minim um distance, the brakes a re au toma tically
pre pare d fo r emer gency b rak ing by the driver . The brake pads are
moved very close to t he b rake discs wi thou t ac tually b rak ing t he
vehicle . This bra ke ass istant feature reacts more quickly to t he
dr iv er 's brak ing, and a lso wo rks wh en Ada ptiv e Cr uise Contro l is off .
T he stopping distance is reduced as a result of this advance b rak e
pre par at ion. Th is fu n ction does n ot p erform a ny eme rgency brak ing
maneuve rs by itself; t he d river must always app ly the brakes.
& WARNING
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions. 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 C ru ise Control m ay 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.
