Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 24). Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the defrost windscreen function
briefly, if required
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control
regulates the temperature and the humidity
of the vehicle interior and filters out undesir-
able substances from the air.
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control is only operational when the engine is running.
Optimum operation is only achieved with the
side windows and panorama sliding sunroof
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 133).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 84). Thiswill 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 Service Booklet. As it
depends on environmental conditions, e.g. heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed in order to
dry the air-conditioning system. The vehicle is ventilated for 30 minutes. 122

If you switch on air-recirculation mode, the
windows can mist up more quickly, in partic-
ular at low temperatures. Only use air-recir-

You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
