defroster as soon as the rear window is

deactivated after approximately

the outside temperature.
Warning! G
Any accumulation of snow and ice should be
removed from the rear window before
driving. Visibility could otherwise be
impaired, endangering you and others.

As soon as the battery has sufficient
voltage, the rear window defroster
automatically turns itself back on.
