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.
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.
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.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (

Y page 95). Have the bulbs that94

Important safety notes
G
WARNING
The windshield will not 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/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. Windshield wipers

For this reason, you should always switch
off the windshield wipers in dry weather.
In the ° position, the appropriate wiping
frequency is set automatically according to
the intensity of the rain.
Intermittent wiping is interrupted if you stop

i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are

note that your vehicle may

described. This also applies to safety-

Important safety notes
G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled

replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a blocked filter replaced at a Mercedes-
Benz Center as soon as possible. G
WARNING
Follow
the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.
Automatic climate control controls the
temperature and the humidity in the vehicle
interior and filters undesirable substances
from the air.
The automatic climate control is only
operational when the engine is running 4
.
Optimum operation is only achieved if you
drive with the side windows and sliding
sunroof closed. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 69).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter can filter out most
particles of

dust, and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet.
4 The residual heat function can only be switched on/off if the ignition is switched off.104
