operate when the engine is running.
F Press this button to demist/defrost the
rear screen and (depending on version)
the door mirrors. The indicator lamp
associated with the button comes on.
Switching off

automatically to prevent an excessive
consumption of current.
F It is possible to stop the demisting/
defrosting operation before it is switched
off automatically by pressing the button
again. The indicator lamp associated with
the button switches off.

of the rear screen and door mirrors
as soon as appropriate, as reducing

reduced fuel consumption.
