Alter the air distribution by turning
the air vents.
The heater is operational when the engi-
ne is running. Depending on the tempe-
rature selected and the outside
temperature, it heats or ventilates.
The dust filter removes most dust partic-
les and pollen from the outside air. The interval for replacing the filter de-
pends on environmental factors, e.g.
high air pollution. The interval may be
shorter than that indicated in the Ser-
vice Booklet.!
CAUTION
Never close all the air vents, other-
wise there is a risk of damage to the
air-conditioning system in the rear
compartment.

Warning
G
Follow the settings recommended on the
following pages for heating or cooling.
The windows could otherwise fog up. As a
result, you could be distracted from road
and traffic conditions and cause an acci-
dent.
Warning
G
Air flowing out of the air vents in the foot-
well when the heater is in operation may
be very hot. There is, therefore, a risk of
burns to bare skin in the immediate proxi-
mity of these outlets. Keep bare skin away
from these air outlets. If necessary, direct
the airflow into a different area of the ve-
hicle interior using the air distribution
control.
