Overview of climat
econtrol systems General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To preven tthe windows from mistin gup:
R switch off climate control only briefly
R activat eair-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activat ethe windscreen demistin gfunction
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improvin gthe interior
climate.
The "Cooling with air dehumidification "function
is only available when the engine is running.
Optimum climate control is only achieved with
the side windows and roof closed.
The residual heat function can only be activated or deactivated with the ignition switched off
(Y page 136).
i Ventilate the vehicle for
abrief period during
warm weather, e.g. using the "Convenience
opening "feature (Y page 94). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odours. Aclogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alway sobserve
the interval for replacing the filter, which is
specified in the Service Booklet. As this
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 blower may be activa-
ted automatically 60 minutes after the key
has been removed depending on various fac-
tors ,e.g. the outside temperature. The vehi-
cle is then ventilated for 30 minutes to dry the automatic climate control. Overview of climat
