Important safety notes

following pages. The windows could other-
wise fog up.

R
switch on air-recirculation mode only
R
briefly
switch on the cooling with air dehumidifi-
R
cation function
switch on the defrost windshield function
R
briefly, if required
Climate control regulates the temperature
and air humidity in the vehicle interior. The
interior filter cleans the air, thus improving
the interior climate.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. Optimum climate control is only ach-
ieved with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (

i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odors. 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.
i It is possible that the blower may be acti-
vated automatically 60 minutes after the
SmartKey has been removed depending on
various factors, e.g. the outside tempera-
ture. The vehicle is then ventilated for
30 minutes to dry the climate control sys-
tem.
