Risk of accident
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
Condensation may drip from the underside of
the vehicle when THERMOTRONIC is in cool-
ing mode. This is normal and not a sign that
there is a malfunction.
The cooling with air dehumidification function
is only available with the air-conditioning sys-
tem or THERMOTRONIC automatic climate
control.
i
The cooling with air dehumidification
function uses refrigerant R134a. This cool-
ant does not contain chlorofluorocarbons,
and therefore does not damage the ozone
layer.
