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.

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.
Observe the settings recommended on the
following pages. The windows could
otherwise fog up. This could prevent you from
observing the traffic conditions, thereby
causing an accident.
Dual-zone automatic climate control
regulates 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 Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 71).
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. 92
