Switching cooling on/off
The cooling function is operational when
the engine is running and cools according
to the temperature selected for the vehicle
interior. The cooling function also dries the
air inside the vehicle, thereby providing
effective protection against the windows
misting up.
G
Risk of accident
If you switch off the cooling function, the
vehicle will not be cooled in the event of
warmer weather conditions. The windows
could therefore mist up more quickly. As a
result, you may no longer be able to observe
road and traffic conditions and cause an
accident.
H
Environmental note
Automatic air conditioning requires less
energy when the cooling is switched off. You
can then reduce your fuel consumption and
cause less environmental damage.
Switching off
You can switch off the cooling function. Air
in the vehicle is then neither cooled nor
dried.
Press the ± button.
The indicator lamp in the ± button
lights up. After a delay the cooling func-
tion switches off.
Switching on
The windows may mist up if the air is
damp. You can use the cooling function to
dry the air.
Press the ± button.
The indicator lamp in the ± button
goes out. The cooling function is
switched on.
