When switched on, adapt ive light adjusts to
curves depending on the vehicle speed and
steering wheel ang le . This provides better
lighting throug h the curve . The system oper ­
ates in a speed r ange from approximately
6 mph (10 km/h) to 68 mph (110 km/h).
Static co rnering light* (vehicles with adaptive
light) -the corn ering light switches on auto­
matica lly when the steering wheel is turned at
a certa in angle at speeds up to approximately
44 mph (70 km/h) and when the turn signal is
activated at speeds up to approximately
25 mph (40 km/h). The area to the s ide of the
vehicle is il luminated better when turning .
Speed dependent light distr ibution* -The
speed dependent light distribution adapts the
light in towns and on highways or express­
ways. Intersect ions can also be ill uminated on
ve hicl es w ith a navigation system *.
Highwa y light funct ion *
(Vehicles with adaptive light or L ED head ­
lights) -This function adapts the light ing for
h ighway driving based on vehicle speed .
_&. WARNING
-Automati c headlights* are only intended
to assist the dr iver . T hey do not re lieve
the drive r of responsibility to check the
head lights and to turn them on man ually
according to the current light and visibili­
ty conditions. For examp le, fog cannot
be detected by the light sensors. So al­
ways switch on the low beam under
these weather conditions and when driv­ ing in the dark
fD.
- Acc idents could occur if you cannot see
the road ahead of you well and if others
on the road cannot see you . A lways
swit ch you r headlights o n so that yo u can see the road ahead of you and others can
see your vehicle from beh

- Please observe legal regulations when
using the lighting systems described.
(D Note
The rear fog lights shou ld only be turned
on in accordance with t raffic regu lations,
to prevent glare for traffic behind your ve­ hicle.
(D Tips
- The light sensor for the automatic head ­

you will hear a warning tone.
- The tail lights do not sw itch on when the
daytime r unning lights switch on.
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They w ill clear shortly after
switching them on . This does not affect
the serv ice life of the lighting.

when the vehicle is stationary and the lever is
tapped in the ® position, or once the vehicle
speed exceeds approximately 2 mph (4 km/h).
The higher the sens itiv ity of the ra in sensor is
set (switch @to the right), the earlier the

A WARNING
-The rain sensor is only intended to assist
the driver. The driver is still responsible
for manually switching the w ipers on ac­
cording to the v is ibility conditions.
- The windshield may not be treated w ith
water-repe lling windshie ld coat ing
agents. Unfavorable conditions, such as
wetness, darkness or low sun, can result in increased glare. W iper blade chatter is
also possible.
- Properly functioning windshie ld w iper
blades are required for a clear view and
sa fe driving
¢ page 54, Replacing
front windshield wiper blades.
0 Note
- In case of frost, make sure the wind­ shield wiper blades are not frozen to the
windshield. Sw itching on the windshield
wipers when the blades are frozen to the
windshield can damage the wiper blades.
- Prior to using a car wash, the windshield
wiper system must be switched off (lever
in position 0). This prevents unintention­
al sw itching on and damage to the wind­
shield wiper system.
- Do not use the wipers to remove ice from
the windows. Using windshield wipers as
ice scrapers destroys the wiper blades.
{D Tips
- The windshield wipers switch off when
the ignition is turned off. You can acti­
vate the w indshield wipe rs after the igni­
tion is switched back on by moving the
windsh ield wiper leve r to any pos ition.
- Worn or dirty windsh ield wiper blades
result in streaking. Th is can affect the
rain sensor function. Check your w ind­
s h ield wiper blades regularly.
- The washer fluid nozzles in the w ind­
shield washer system are heated* at low
temperatures when the ignit ion is on.
- When stopping temporarily, such as at a
traff ic light, the speed of the windsh ield wipers automatically reduces by one
lev­
el.
- In vehicles with an MMI, you can switch
the rain sensor or off in the
Driver a ssi s­
t a nce
menu.
Cleaning windshield wiper blades
Clean the wiper blades when you see wiper
streaks . Use a soft cloth and a glass cleaner .
.,. Place the windshie ld wiper arms in the serv­
ice pos it ion
¢ page 54.
.,. Fold the windshield wiper arms away from
the windshield.
A WARNING
Dirty windsh ield wiper blades can impair
v is ion, wh ich increases the r isk of an acci­
dent.
(D Note
If you see streaks again after clean ing the
wiper blades, the blades must be replaced

Removing the wiper blade
• Fold the windshield wiper arm away from
the windshie ld .
• Press the locking knob@¢
fig. 50 on the
wiper blade. Hold the wiper blade firm ly.
• Remove the wiper blade in the direction of
the arrow.
In sta ll ing th e wiper blade
• Insert the new wiper blade into the mount
on the wiper arm @until you hear it latch
into place.
• Place the wiper arm back on the windshie ld.
• Turn the service pos ition
off.
A WARNING
For safety reasons, the windshield wiper
blades should be replaced once or twice
each year.
(D Note
- The windshield wiper blades must only
be folded away when in the serv ice posi­
tion. Otherw ise, you risk damaging the
paint on the hood or the wi ndshield wip­
er motor.
- You should not drive your veh icle or
press the w indshield w iper lever when
the w iper arms are folded away from the
windsh ield . The w indshield w ipers would
move back into their origina l position
and could damage the hood and wind­
shield.
- To prevent damage to the windshield
washer system, always loosen w iper
blades that have frozen to the wind­
s h ield before turning the wipers on.
- To prevent damage to the wiper blades,
do not apply gasoline, petroleum, thin­
ning agents or other solvents on the wip­
er blades or near them.
- To prevent damage to the wiper arms or
other components, do not try to move
the windshie ld w ipers by hand .
-
Lights and Visi on 55
@ Tips
-Commercial hot wax such as t he types
used by car washes make it more d ifficult
to clean t he windshie ld.
- Yo u can also use the service position, for
example, if yo u want to protect the
w indshield from icing by using a cover .
- Yo u cannot activate the serv ice position
when the hood is open.

c::> page 36. When you lock the vehicle , the
mirrors fold in . When you sta rt the ignit ion,
the m irrors fold out .
A WARNING
Curved mirror s urfaces (convex or asphe­
ric*) enlarge the field of vision. However,
they make objects in the mirror appear sma ller and farther away . Your may esti­
mate incorrectly when you use these m ir­
rors to gauge your d istance from the
veh icles behind you when changing lanes -
accident risk!
@ Note
- For vehicles with power folding exterior
mirrors*: If the m irror housing was
moved by outside forces (such as an im­
pact when maneuvering), you must use
the power folding function to fold the mirro r all the way out. You will hear a
l oud noise when the m irrors are latched
back in place. The mir ror housi ng must
not be moved back into place by hand
because this would affect the mirror
mechan ism.
- Applies to vehicles witho ut power fold­
i ng exter ior mirrors: If the mirror hous­
ing was moved by outside forces (suc h as
in impact during maneuvering), you
must move the m irror housing back into
place by hand.
- If you wash the vehicle in an automatic
car wash, yo u m ust fold the e xterior m ir­
r o rs in to reduce the risk of damage to
the m irrors. Never fold power fo ld ing ex-
-
terior mirrors by hand . On ly fold them in
and out using the power controls.
(D Tips
If t he power ad justmen t fails, bot h mir­
ro rs can be adjusted by hand by pressing
on the edge of the mirror surface.
