the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work onthe Xenon bulbs carried out at a qualified spe-
cialist workshop.
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
Do not use a bulb if it has been dropped or if its glass tube has been scratched.
The bulb may explode if:
Ryou touch it
Rit is hot
Ryou drop it
Ryou scratch it
Use bulbs only in closed lamps that have been
designed for this purpose. Only install spare
bulbs of the same type and the specified volt-
age.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
tube when cold with alcohol or spirit and rub it
off with a lint-free cloth.
Protect bulbs from moisture during operation.
Do not allow bulbs to come into contact with
liquids.
Xenon bulbs and LED modules: in addition to
the Xenon bulbs, there are LED modules which
you cannot change yourself.
Have the following bulbs replaced at a qualified
specialist workshop:
RHigh-mounted brake lamp
RAdditional turn signals in the exterior mirrors
RParking lamps/standing lamps (front)
RHigh-beam/low-beam headlamps (Xenon
headlamps)
RDaytime running lamps
RLicense plate lamp
RSide marker lamps
iIndividual segments of the license plate
lamp LEDs may fail without a display message
appearing in the multifunction display. Regu-
larly check the license plate lamp. If neces-
sary, visit a qualified specialist workshop.
You can replace the following bulbs:
RTurn signal lamp (front)
RBrake/tail lamp
RTurn signal lamp (rear)
RTail lamps/standing lamps
RBackup lamp
RRear fog lamp
Replace only the bulbs listed (
Ypage 90).
Have the bulbs that you cannot change yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult a
qualified specialist workshop.
Headlamps and lights 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.

Windshield wipers
Switching the windshield wipers
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield/rear window can
scratch the glass if wiping takes place when
the windshield/rear window 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.
!If the windshield wipers leave smears on the
windshield/rear window after the vehicle has
been washed in an automatic car wash, this
may be due to wax or other residue. Clean the
windshield/rear window with washer fluid
after an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield 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 Åposition,
the rain sensor is more sensitive than in the
Ä position, causing the windshield wiper to
wipe more frequently.
Intermittent wiping is interrupted if you stop the vehicle and open a front door. This protects
people getting into and out of the vehicle from
being sprayed with water.
Intermittent wiping continues when all doors are
closed and:
Ryou shift the automatic transmission to drive

Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!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 wind-
shield. Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
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 a qualified spe-
cialist workshop.

Overview of the climate control sys-
tem
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Ractivate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The "Cooling with air dehumidification" function
is only available when the engine is running.
Optimum operation is only achieved when the
side windows and the sliding sunroof are closed. The climatic comfort deteriorates whilst the slid-
ing sunroof is open. Set the temperature man-
ually if the sliding sunroof is open.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 102).
The integrated filter can filter out most particles
of dust and completely filters out pollen. A clog-
ged filter reduces the amount of air supplied to
the vehicle interior. Depending on the operating
conditions and environmental influences, the
interval for replacing the filter may be shorter
than specified.
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 70). This will speed
up the cooling process and the desired vehi-
cle interior temperature will be reached more
quickly.
