is only available when the engin eisrunning.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted. G
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 preven tyou from observing the traffic conditions, thereby caus-
ing an accident.
Condensation may drip from the underside of
the vehicle when THERMOTRONI Cisincool-
ing mode. This is norma land not asign that
there is amalfunction.
i The cooling with air dehumidification
function uses refrigerant R134a. This cool-
ant does not contain chlorofluorocarbons,
and therefor edoes not damage the ozone
layer.
