WARNING
Observ ethe settings recommende donthe
followin gpages. The windows could other-
wise mist up. This may preven tyou from
observing the traffic conditions, thereby caus-
ing an accident.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control is only operational when the
engine is running. The system only works
optimally if the side windows and the roof are
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 147).
i Ven tilate the vehicle for abriefp eriod
during war mweather ,e.g. using the con-
venienc eopening feature (Y page 90).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached mor equickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior .For
this reason, you should always observ ethe interval for replacing the filter
,which is
specifie dinthe Servic eBooklet .Asit
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Servic eBooklet. 136
