Adaptive Highbeam Assist
GWarning!
The Adaptive Highbeam Assist is only an aid
intended to support you 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.
You can use this function to set the
headlamps to change between low beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the 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.XTo activate: activate the Adaptive
Highbeam Assist function using the on-
board computer ( Y page 209).XTurn the light switch to c.XPress the combination switch beyond the
pressure point in the direction of arrow :

Changing bulbs
Important safety notes
Xenon bulbs
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.
GWarning!
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 Xenon bulbs yourself, but have
them replaced at a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at 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.
Other bulbs
GWarning!
Bulbs and lamps can be very hot. You should
therefore allow them to cool down before you
change them. Otherwise, you could be burned
if you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could damage the bulbs, for
example, and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may break or even explode and
injure you.
Halogen bulbs are pressurized and can
explode when you change them, particularly
if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y page 127). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.

Windshield wipers
Important safety notes
GWarning!
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
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always
use washer fluid when operating the
windshield wipers.

! Intermittent wiping with rain sensor: due
to optical influences and the windshield
becoming dirty in dry weather conditions,
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 Ä or Å position, the appropriate
wiping frequency is automatically set
according to the intensity of the rain. In
the Å position, the rain sensor is more
sensitive than in the Ä position, causing
the windshield wipers to wipe more
frequently.

Replacing the wiper blades
Important safety notes
GWarning
For safety reasons, switch off the windshield
wipers and remove the key 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.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! 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 can be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades replaced by a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center.
Replacing the windshield wiper blades
Removing the wiper blades
XRemove the key from the ignition lock or
turn the key to position 0 (KEYLESS-GO).
XFold the wiper arm away from the
windshield until it engages.
XSet the wiper blade at right angles to the
wiper arm.
XRemove the wiper blade from the retainer
on the wiper arm in the direction of the
arrow.
Installing the wiper blade
XSlide the new wiper blade into the retainer
on the wiper arm in the opposite direction
to the arrow.
Make sure that the wiper blade slides fully
into the retainer on the wiper arm.
XTurn the wiper blade parallel to the wiper
arm.
XFold the wiper arm back onto the
windshield.
