Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The
defroster is automatically deactivated
after approximately 6 to 20 minutes of
operation depending on the outside tem-
perature.

When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could re-
sult in an accident and/or serious personal
injury.
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, this
means that too many electrical consumers are
operating simultaneously and there is insuffi-
cient voltage in the battery. The system re-
sponds automatically by deactivating the rear
window defroster.
As soon as the battery has sufficient voltage, the
rear window defroster automatically turns itself
back on.
