Cornering ligh
tfunction The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. The
cornering light function can only be activated
whe nthe low-beam headlamps are switched
on.
Active:
R if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signals
or turn the steering wheel
R if you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel
Not active: if you are driving at speeds above
25 mph (40 km/h) or switch off the turn
signals or turn the steering wheel to the

The cornering light function may remain lit for
a short time, but is automatically switched off
after no more than three minutes. Adaptive Highbeam Assist
You can use this function to set the
headlamps to change between low bea mand
high beam automatically. The system
recognizes vehicles with thei rlights on, either
approaching fro mthe opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam. The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detects any other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel. X
To activate: activate the Adaptive
Highbeam Assist function using the on-
board computer (Y page 350).
X Turn the light switch to c.

28 mph (45 km/h):
the headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you are driving at speeds above
approximately 35 mph (55 km/h) and no
other road users have been detected: 254
Exterior lightingLights and windshield wipers

the high-beam headlamps are switched on
automatically. The Kindicator lamp in
the instrument cluste ralso lights up.
If you drive at speeds below approximately
30 mph (45 km/h) or if other road users
are identified or if the roads are sufficiently
illuminated:
the high-beam headlamps are switched off
automatically. The Kindicator lamp in
the instrumen tcluster goes out. The _
indicator lamp in the instrument cluster
stays on.
X To deactivate: move the combination
switch back to its normal position.

cluster goes out. G
WARNING
The Adaptive Highbeam Assist is only an aid
intended to suppor tyou while driving. The
driver is and remains responsible for proper
vehicle lighting in accordance with the
prevailing light, sight and traffic conditions.
The system may be impaired or unavailable
when
R visibility is poor, e.g. due to snow, rain, fog,
or heavy spray
R the optical sensor area of the windshield is
dirty, fogged up, or covered by a sticker for
example
The system cannot recognize the following
road users:
R Road users without a lighting system of
their own, e.g. pedestrians
R Road users with dim lighting of their own,
e.g. cyclists
R Road users whose lighting is obstructed,
e.g. road users behind a guardrail
R In some seldom cases, even road users with
a lighting system of their own may be
recognized too late or not at all.
The automatic high-beam headlamps will then
not be deactivated or it will be activated in
spite of preceding or oncoming road users. This could endanger you and/or others and
cause an accident
.Always pay close attention
to the traffic situation and switch off the high
beam manually if necessary. Headlamps fogged up on the inside

Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric contacts on Xenon bulbs. Therefore, never
remove the cover from Xenon bulbs.
Do not change the Xenon bulbs yourself, but
have them replaced at a qualified workshop.
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 257). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs,
consult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when installing.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly. G
WARNING
Bulbs and lamps can become very hot. For
this reason, allow them to cool down before
changing them. Otherwise, you could burn
yourself when you touch them. 256
Replacing bulbsLights and windshield wipers

Keep bulbs out of the reach of children.
Otherwise, they could, for example, damage
the bulbs and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
Halogen bulbs are pressurized and could
explode when you change them, especially if
they are very hot. You should therefore wear
eye protection and gloves when you are
changing them. Overview: changing bulbs/bulb types
You can change the following bulbs. The bulb
type can be found in the legend. Bi-Xenon headlamps

WARNING
Wiper blades are components that are subject
to wear and tear .Replace the wiper blades
twice a year, preferably in the spring and fall.
Otherwise the windshield will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust Windshield wipers

tha
thas collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washe rfluid

! Intermittent wiping with rain sensor: due
to optical influences and the windshield
becoming dirty in dry weathe rconditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather. In the
ÄorÅ position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the Å position, the rain sensor is more
sensitive than in the Äposition, causing
the windshield wipers to wipe more
frequently. Replacing the wiper blades
Important safety notes G
WARNING
For safety reasons, switch off the windshield
wipers and remove the SmartKey from the
ignition lock before changing the wiper blades
(vehicles with KEYLESS-GO: make sure that
the on-board electronics are in state 0).
Otherwise, the wiper motor could be switched
on suddenly and cause injury.
! Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades replaced by aqualified
specialist workshop, e.g. at an authorized
Mercedes-Ben zCenter.
! Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
