166 Climate control

Air intake

The air intakes in front of the windscreen on
the far right and left sides of the engine
compartment must be kept clear to allow
air intake. Remove any leaves, dirt or snow.

Air outlet

Do not cover the air outlets when storing
items in the luggage compartment storage
compartments.

Pollen filter

The pollen filter cleans dust, soot, pollen
and spores from the air entering from
outside. The active carbon layer 3
eliminates most odours and harmful
ambient gases from the air.
Have the pollen filter replaced by a
workshop at the replacement intervals
specified in the service booklet.

Note

If the windscreen is misted due to damp
weather, temporarily set the system as
described under "Window demisting and
defrosting", see pages 147, 150, 159.
The cooling system 3 operates most
effectively with the windows and sun roof 3
closed. If the passenger compartment has
heated up considerably after a long period
in direct sunlight, briefly open the windows
and sun roof 3 so that the hot air can
escape quickly.
