The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, turn off the de-
froster as soon as the rear window is
clear.
!
Heavy accumulation of snow and ice
should be removed before activating
the defroster.
The defroster is automatically turned
off after approximately 6-17 minutes of
operation depending on the outside
temperature and vehicle speed.
If several power consumers are turned
on simultaneously, or the battery is
only partially charged, it is possible that
the defroster will automatically turn it-
self off.
When this happens, the indicator lamp
inside the switch starts blinking.
As soon as the battery has sufficient
voltage, the defroster turns itself back
on.
