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 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. 112

Switching the windshield wipers on/
off
G
WARNING
The windshield will no longer be wiped
properly if the wiper blades are worn. This
could prevent you from observing the traffic
conditions, thereby causing an accident.
Replace the wiper blades twice a year, ideally
in spring and fall.
! 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 Windshield wipers
115Lights and windshield wipers Z

use washe
rfluid when operating the
windshield wipers.
! 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 washer fluid
after washing the vehicle in an automatic
car wash.
! 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. Combination switch

In the 0001or0002 position, the appropriate
wiping frequency is set automatically according to the intensity of the rain. In
the
0002 position, the rain sensor is more
sensitive than in the 0001position, 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.
! 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 may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at aqualified
specialist workshop.
! Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood. 116

WARNING
Very hot or very cold air can flow from the air
vents. This could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents. Keep bare skin away from these air
vents. If necessary, direct the airflow away to
a different area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet grille on the hood and in
the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior. i
You can move the adjusters for the air
vents vertically or horizontally to set the
direction of the airflow.
