not need, such as the rear window
defroster or interior lighting.

WARNING
Very hot air can flow out of the AIRSCARF
vents in the head restraints when AIRSCARF
is in operation. This can cause burns on
unprotected skin near the AIRSCARF vents.
Make sure that you reduce the heater output
in time.
The AIRSCARF function warms the head and
neck area of vehicle occupants with warm air.
The warm air flows out of the holes in the head
restraints.

models and all standard and optional
equipment of your vehicle available at the

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.
The automatic climate control regulates the
temperature and the humidity in the vehicle
interior and filters undesirable substances
out of the air.
Coupe: the automatic climate control is only
operational if the engine is running. Optimum
operation is achieved only when you drive
with the side windows closed.
Roadster: the automatic climate control is
only operational if the engine is running. The system only works optimally when the side
windows and the roof are closed.
i
Coupe: ventilate the vehicle for a brief
period during warm weather. This will
speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
Roadster: ventilate the vehicle for a brief
period during warm weather. 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. 102
