lane. For this reason, make sure of the
actual distance from the vehicle driving
behind by glancing over your shoulder .
The convex exterior mirrors give a larger field
of vision.

It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the coolant temperature and
on the interior temperature that has been set.

G
Risk of accident
If you deactivate the cooling function with
air dehumidification, the vehicle will not be
cooled in warm weather and the air will not
be dehumidified. The windows could mis t
up more quickly. This may prevent you from
observing the traffic conditions, thereby
causing an accident. H
Environmental not
e
The cooling system uses the refrigerant
R134A. This refrigerant does not damage
the earth's ozone layer.
i Condensation may drip from the under-
side of the vehicle when Thermatic is in
cooling mode.
Cooling with dehumidification is operational
when the engine is running, and cools accord -
ing to the interior temperature selected. The
air inside the vehicle is also dried, thereby
preventing the windows from misting up.
X To activate :press the œbutton.
