Rear window defroster
The rear window defroster uses a large
amount of power. To keep battery drain to
a minimum, switch off the defroster as
soon as the rear window is clear. The de-
froster is automatically deactivated after
approximately 6 to 17 minutes of
operation depending on the outside tem-
perature.

!
With the sunshade raised and the respective
door window open, the sunshade could disen-
gage and snap back when driving at high vehicle
speeds, e.g. on highways, and damage the
retractor. You should therefore always either
close the door window or lower the sunshade
when driving at high speed.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.
!
If the rear window defroster switches off too
soon and the indicator lamp starts flashing, too
many electrical consumers are operating simul-
taneously and there is insufficient voltage in the
battery. The system responds automatically by
switching the rear window defroster off.
As soon as the battery has sufficient voltage, the
rear window defroster switches back on auto-
matically.
