General information
The w indshie ld wipers and the windsh ield
washer system operate only with the ignit ion
on .
D uring a tempora ry stop, e.g. at a traffic sig­
nal, the set wipe speed is automati cally re­
duced by one stage.
T he w indshie ld washe r nozzles are heated at
low temperatures when the ign ition is o n.
Removing water drop lets
About 5 seconds after the wash cycle is com­
plete, the wiper system performs a s ingle au ­
tomat ic w ipe cycle to remove any wate r d rop­
lets that remain on the w indshie ld w hile d riv­
ing .
If you would like to deactivate this delayed
wipe cycle while driv ing , you have to pull the
lever to position ® agai n w ith in 10 seconds
after this wipe cycle .
Water drop let remova l is reactivated after the
ignition is sw itched off and then on aga in .
Winter posit ion
To speed up de-icing of the windsh ield wipe rs,
they move to the w inter po sition when the ig­
nition is switched off and at an outside tem ­
perature below 39
°F (4 °() . In this position,
the windshie ld wipers are in an area on the
glass whi ch is reac hed by the air vents below
the g lass . It i s also easie r to remove snow and
ice from the w indshie ld w ipers in t his posi­
tion.
T he w ipers leave the win ter posi tion, when
the igni tion is switched on, if the w indshield
wiper lever is ope rated or the active rain sen­
sor reacts to moisture.
Rain sensor
T he rain sensor operates only in the interval
wiper pos ition. When it starts to rain, the in ­
te rv al wiper mode is activ ated automatically.
If the windshield wipe r lever is in the interval
wipe position with the ignit ion sw itched 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 in­
crease the sensitivity of the rain sensor, the
switch must be moved up.
The higher the sensitivity setting, the sooner
the windshield wipers react to moisture on
the windshield . Increased sensitivity is sig­
naled by the windshield w ipers making a sin­
gle pass over the windshield.
The rain sensor wiper intervals depend on the
sensitivity setting as well as vehicle speed .
During brief stops, wiper motion will adjust in
relation to the amount of rain on the wind­
shield.
A 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
i:::> page 69, Replacing
windshield wiper blades!
- The rain sensor is only designed to assist
and support the driver.
It remains entire­
ly the driver's responsibility to monitor
outside weather conditions and to man­
ually activate the wipers as soon as rain
or drizzle reduces visibility through the
windshield .
(D Note
In freezing or near freezing 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 wiper motor .
- Do not use the wipers to clear a frosted
window . Using the wipers as a conven­
ient ice scraper will destroy the wiper
blades .
Clear vision 67
-Prior to using a car wash, the w indshield
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.
(1} 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 w iper 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
i:::> page 2 70 for checking and filling the
washer container.

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 224.
-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

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
If a slower vehicle d riving ahead is detected,

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 115 .
If the vehicle in front accelerates, adaptive
cru ise control also accelerates up to the speed
that you have set.
I f the vehicle ahead slows to a stop, ACC will
slow yo ur 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 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" .
D epressing the brake pedal turns
off ACC.
When the vehicle ahead accelerates yo u can
reactivate ACC
¢ page 120, 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 ¢
page 126 .
Adapti ve crui se control 117
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 istan ce
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 .
