Overview of the climat
econtrol sys-
tem General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R activate the "Cooling with dehumidification"
function
R activate the "Windscreen demisting" function
briefly, if required
Climate control regu lates the temperature and
the humidity in the vehicle interior and filters
undesirables ubstances out of the air. The "Cooling with air dehumidification" function
is available only when the engin eisrunning.
Optimum operation is only achieved when the
side windows and the sliding sunroof are closed.
Climate comfor tmay be adversely affected if the
sliding sunroof is open for along period of time.
Set the temperature manually if the sliding sun-
roof is open.
The "Residual heat" function can be switched on or off only when the ignition is switched off
(Y page 89).
The integrated filter can filter out most particles of dust and completely filters out pollen. Aclog-
ged filter reduces the amount of air supplied to
the vehicle interior. Dependin gonthe operating
conditions and environmental influences, the
interval for replacing the filter may be shorter
than specified. Control panel for THERMATIC automatic climate control (dual-zone)

briefly, e.g. if there are unpleasant outside
odours or when in atunnel. The windows
could otherwise mist up as no fresh air is
drawn into the vehicle in air-recirculation
mode.

can mist up more quickly. Therefore, only deactivate the "Cooling with air dehumidification" function briefly.
The "Cooling with dehumidification" function is available only when the engine is running.
The air inside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when cooling mode is active. This is normal
