Important safety notes G
WARNING
For safety reasons, switch off the wipers and
remove
the SmartKey from the starter switch
before replacing a wiper blade. Otherwise, the
wiper motor could suddenly turn on 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/
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
specialist workshop.

Useful information
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
possible.
Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

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.
Automatic
climate control is only operational
when the engine is running. Optimum
operation is only achieved if you drive with the
side windows and sliding sunroof closed.
The climatic comfort deteriorates whilst the
sliding sunroof is open. The automatic climate
control cannot maintain the set temperature with the sliding sunroof open. You have to
adjust the climate control manually.
i
The "residual heat" function can only be
activated or deactivated with the ignition
switched off.
i The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 134).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 78).
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.
Since the replacement interval depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet. 118

The following contains notes and
recommendations on optimum use of
automatic climate control.
R Activate
climate control using the à and
Á buttons. The indicator lamps in the
à and Á buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "defrosting" function briefly
until the windshield is clear again. R
Only use "air-recirculation" mode briefly,
e.g. if there are unpleasant outside odors
or when in a tunnel. The windows could
otherwise
fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well. The
indicator lamp in the á button goes out.120

WARNING
If you switch off the cooling function, the vehicle will not be cooled when weather conditions are
warm. The windows can fog up more quickly. Window fogging may impair visibility and endanger
you and others.
The cooling with air dehumidification function is only available when the engine is running.
The air inside the vehicle is cooled and dehumidified according to the temperature selected. 124
