The front and rear light clusters of your vehicle
are equipped with LED bulbs. Do not replace the
vehicle's bulbs yourself. Contact a qualified spe- cialist workshop with the necessary specialist
knowledge and tools to carry out the work
required.
Lamps are an important aspect of vehicle safety.
You must therefore make sure that these func-
tion correctly at all times. Have the headlamp
setting checked regularly. Replacing bulbs (vehicles with halo-
gen headlamps) Important safety notes

WARNING
Bulbs, lamps and plug connectors can
become very hot during use. When replacing a bulb, you could burn yourself on these com-
ponents. There is a risk of injury. Allow these components to cool down before
replacing the bulb.
Do not use a bulb if it has been dropped or if its
glass tube has been scratched.
The bulb may explode if:
R you touch it
R it is hot
R you drop it
R you scratch it
Use bulbs only in closed lamps that have been
designed for this purpose. Fit only spare bulbs of the same type and the specified voltage.
Marks on the glass tube reduce the service life
of the bulb. 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.
Replace only the bulbs listed (Y page 126).
Have the bulbs that you cannot replace yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb does not light up either, consult
a qualified specialist workshop.
Headlamps 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. Overview of bulb replacement - bulb
types
You can replace the following bulbs. The details for the bulb types can be found in the legend. 126

Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen wipers in dry weather conditions, always
operate them using washer fluid.
! If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind- screen with washer fluid after an automatic
car wash.
! Intermittent wiping with rain sensor: due to
optical influences and the windscreen becom-
ing dirty in dry weather conditions, the wind-
screen wipers may be activated inadvertently. This could damage the windscreen wiper
blades or scratch the windscreen.
For this reason, you should always switch off
the windscreen wipers in dry weather. Combination switch

X Turn the key to position 1or 2in the ignition

X Turn the combination switch to the corre-
sponding position.
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 windscreen wiper to
wipe more frequently.
Vehicles with MAGIC VISION CONTROL: the
washer fluid is fed through the wiper blades and when wiping with washer fluid îthe washer
fluid is emitted directly from the blades.
If the wiper blades are worn, the windscreen will
no longer be wiped properly. This could mean
you are unable to observe the traffic conditions. 128

Important safety notes G
WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! Never open the bonnet/tailgate if a wiper
arm is folded away from the windscreen/rear
window.
Never fold a windscreen wiper arm without a
wiper blade back onto the windscreen/rear
window. Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release the
wiper arm without a wiper blade and it falls
onto the windscreen/rear window, the wind-
screen/rear window 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.

control
Optimum use of the automatic climate
control The following contains notes and recommenda-
tions on how best to use THERMATIC automatic climate control or THERMOTRONIC.
R Activate climate control using the Ãand
Á buttons. The indicator lamps in the
à andÁ buttons light up.
R Vehicles with THERMOTRONIC:in auto-
matic mode, you can also use the ñbutton
to set a climate mode (FOCUS/MEDIUM/
DIFFUSE). The MEDIUM level is recommen-
ded.
R Set the temperature to 22 †.
R Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use air-recirculation mode only briefly, e.g. if
there are unpleasant outside odours or when
in a tunnel. The windows could otherwise mist up as no fresh air is drawn into the vehicle in
air-recirculation mode. R
Vehicles with THERMOTRONIC:use the
ZONE function to adopt the temperature set-
tings on the driver's side for the front-
passenger side and the rear compartment as well. The indicator lamp above the ábut-
ton goes out.
R Vehicles with THERMOTRONIC:use the
"residual heat" function if you want to heat or
ventilate the vehicle interior when the ignitionis switched off. The residual heat function can
be activated or deactivated only with the igni- tion switched off.
R If you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
During automatic engine switch-off, the climate
control operates only at a reduced capacity. If
you require the full climate control output, you
can switch off the ECO start/stop function by
pressing the ECO button (Y page 153).134
