dealership.
Adaptive light *
The benefit of adaptive l ight is that the curve
and the edge of the road are better i llum inat­
ed . The adaptive light is contro lled automati­
cally, depending on vehicle speed and steering
wheel angle.
When driving a round bends, the head lights
are contro lled according to steering wheel an­
g le . So that there is no black area ahead of the
ve hic le, the two main beams pivot at different
angles. The system works above a speed of
about 6 mph (10 km/h).
Com ing home /le avi ng home function *
The function is swit ched on when the switch is
in the AUTO* position and the function is
shown as active in the driver information sys­
tem.
The
coming hom e function illuminates the
area around the vehicle when the ign ition is
switched off and the driver's door is ope ned.
The length of time the lights remain on can be
set in the menu display
( Illumination > Exte­
rior lights > coming home ).
The leavi ng home function i lluminates the
area around the vehicle when unlocking it.
A WARNING
- Never use dayt ime running l ights to see
where you are going. They are not bright
enough and w ill not let you see far
enough ahead for safety, especially at
dusk or when it is dar k. Always switch on
the low beams at dusk or when i t is dar k.
- Automatic headlights a re only intended
to assist the dr iver. They do not re lieve
t he driver of his responsibi lity to check
t he headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
and rain cannot be detected by the light
sensors. So a lways switch on the head­
lights under these weather cond itions
and when driving in the dark
jO .
Clear vis ion 49
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists.
- Always turn on the headlights so that
youcanseeahe adandsothatothe ~
can see your car from the back .
- Please observe legal regulat ions w hen
using the ligh ting systems des cribed.
(D Tips
- T he light sensor for head light control is
located in the rear view mirror mount.
Do not apply any stickers to t he wind­
shield in th is area to preven t malfunc­
tions or fa ilures.
- Some exter io r l ighting funct ions can be
adjusted in t he driver i nformat ion sys­
t em
~page 24.
- I f you remove the igni tion from t he igni ­
t ion lock while the headligh ts are s till
on, a buzzer wi ll sound as long as the
driver's door is o pen to remind yo u to
t u rn off the lights.
- Always observe the specific local regula ­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam f unction is also available, but w ith
one restrict ion: If you have not sw itched
the high beams back to low beams dur­
ing automatic headlight operation (for
example, after d riving throug h a tunnel),
only the low beams come on the next
t ime au tomati c headlights a re swi tched
on. To use the high beams , you firs t have
t o pull the hig h beam lever back and
then push the lever fo rward again .
- In coo l or damp weather, the inside of
the headlights, turn signals an d tail
lights can fog over due to the tempera­
t u re difference between the inside and
outside. They w ill clear shortly after
switching them on. This does not affect
the se rv ice life of the lighting.

- If the mirror housing is moved uninten­
tionally (for example, while parking your
vehicle), then you must first fold the mir­ ror electrically. Do not readjust the mir­
ror housing manually. You could damage
the motor which controls the mirror .
- If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
the mirrors . Never fold power folding ex­
terior mirrors* by hand. Only fold them in and out using the power controls .

Wiper and washer system
Windshield wiper
The windshield wiper lever controls both the
windshield wipers and the washer system .
Fig. 63 Wiper lever: win ds hield w iper lever pos it ions
T he windshield wiper lever i=:> fig. 63 has the
following positions:
Int ermittent wiping ~l (activating rain
s e nsor)*
.. Move the lever up to position (D .
.. Move the interval set switch @, to change
the intervals.
Low wiper spe ed
.. Move the lever up to posit ion @.
High w ipe r speed
.. Move the lever up to posit ion @.
One-touch wip ing
.. Move the lever to position @ , when you
want to wipe the windshield
briefly.
Automat ic wip er/ washer
.. Pull the lever to position ® (t oward the
steering whee l) and hold .
.. Release the lever . The washer stops and the
w ipers keep going for about four seconds.
Turning off the wipers
.. Move the lever back to position @ .
The w indshield w ipers and washer only work
when the ignition is turned on . If you sw itch
off the igni tion with the windshie ld w iper lev­
er st ill in the inte rva l wipe position and then
come back a whi le later and drive off, the ra in
sensor will reactivate itself after the vehicle speed has exceeded 4 mph (6 km/h) .
T he rai n sensor* is only activated with the
wiper lever set to position
(D . When it starts
to rain, the rain senso r will a utomat ically acti­
vate the intermittent wiping mode .
T o reduce the sensi tivity of the sensor, move
swi tch @ down . To increase the sensi tivity,
move the switc h up. The higher you adjust the
sensitivity, the faster the senso r will react
when it senses moisture on the windsh ield.
The pauses between wiper turns depend not only on the sensitivity setting, but on the ve-
hicle speed as well. ..,.

During brief stops, e.g. at a red light, wiper
motion will automatically be reduced to the
next lower speed. Wipers already turning at
low speed change to intermittent wiping.
When the ignition is turned on, the washer
jets are heated.
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 uncompromising visibility .
Worn or damaged wiper blades are a safety hazard ¢
page 5 7, Replacing
windshield wiper blades!
- The light/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 in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter .
(I) 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.
- Before you take your vehicle to an auto­
matic car wash, make sure you have the
windshield wiper system switched off (lever in position 0), otherwise the wind­
shield wiper system could get damaged

in the car wash if it should suddenly
come on.
(0 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 light/rain sensor* . Check
the condition 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.
-Applies to vehicles with light/rain sen­
sor : When the wipers are switched on
manually and in rain conditions, the au­
tomatic headlights* turn on¢
