Good visibility
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.
Activating
̈ Switch on the ignition ( ୴ page 38).
̈ Press button 1 on the climate con-
trol panel ( ୴ page 218) or the automat-
ic climate control* panel ( ୴ page 232).
The indicator lamp on the button
comes on.
Deactivating
̈ Press button 3 again.
The indicator lamp on the button goes
out.
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 con-
sumers are operating simultaneously
and there is insufficient voltage in the
battery. The system responds automat-
ically by switching the rear window de-
froster off.
As soon as the battery has sufficient
voltage, the rear window defroster
switches back on automatically.
