WARNING
Any accumulation of snow and ice should be
removed from the rear window before driving.
Visibility could otherwise be impaired, endangering you and others.
The rear window defroster has a high current draw. You should therefore switch it off as soon as the window is clear as it only switches off automatically after several minutes.
