outside temperature is displayed, for ex-
ample after leaving a garage. There may
also be a short delay before a rise in the
outside temperature is displayed. This
prevents you from seeing a temperature
display influenced by heat from the engine
when the vehicle is stationary or moving
slowly.

Tempmatic is only operational while the
engine is running. You can use Tempmatic
to regulate or control the temperature au-
tomatically. The vehicle is either heated or
cooled, depending on the temperature se-
lected and the outside temperature.
The combination filter removes most dust
particles, pollen and unpleasant odors
from the outside air.
The interval for replacing the filter depends
on environmental factors, e.g. high air pol-
lution. The interval may be shorter than
that indicated in the Service Booklet.

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 accident.Warning
G
Air flowing out of the air vents in the footwell
when Tempmatic is in operation may be very
hot or very cold. There is therefore a risk of
frostbite or burns to bare skin in the imme-
diate proximity of these outlets. Keep bare
skin away from these air outlets. If neces-
sary, direct the airflow into a different area
of the vehicle interior using the air distribu-
tion control.
