HEATING, VENTILATION AND

AIR CONDITIONING

Outside air
Always keep the air intakes free of
snow, leaves etc., to allow the
system to function effectively.
Recirculated air
When recirculated air is selected,
only the air currently in the
passenger compartment will be
circulated. Outside air will not enter
the vehicle.
Note: It is not recommended to use
recirculated air for more than
30 minutes as there is no air
exchange and the windows may
mist up.
Fresh air filter
The fresh air filter removes most
potentially harmful particles such
as pollen, industrial fallout and road
dust from entering the vehicle's
interior. The active carbon filter
also removes odours.
In an automatic car wash, you
should switch off the ventilation
blower to prevent the filter
collecting wax deposits.
The fresh air filter should be
replaced in line with the service
intervals shown in the Warranty
and Service Guide .
Ventilation
Note: The ventilation system emits
noises. This is normal and can be
disregarded.

Heating
The temperature can be adjusted.
Note: The heating depends upon
the coolant temperature and is
therefore only effective when the
engine is warm.
Air conditioning
The air is directed through the
coolant heat exchanger where it is
cooled if the air conditioning is
switched on. In addition, humidity
is extracted from the air to help
keep the windows free of mist.
The resulting condensation is
directed to the outside of the
vehicle. It is therefore quite normal
if you notice a small pool of water
underneath the parked vehicle.
Note: The air conditioning system
only operates when the
temperature is above +5
engine is running and the blower is
switched on.
the air conditioning system off
when it is no longer needed or
select recirculated air.
Switching off the air conditioning
can lead to a reduction in comfort
levels and, under certain
circumstances, cause the windows
to mist up.
