Rear Window Defroster
The switch is located in the center
console.
Turn key in steering lock to
position 1 or 2.
Press symbol side of rocker switch
to turn on, bottom to turn off.
When activating the rear window
defroster, the indicator lamp in the
switch will come on.
Note:
The rear window defroster uses a
large amount of power. To keep
the battery drain to a minimum,
turn off the defroster as soon as
the window is clear. The defroster
is automatically turned off after a
maximum of 20 minutes of opera­
tion. Heavy accumulation of snow
and ice should be removed before
activating the defroster.
If several power consumers are
turned on simultaneously, or the
battery is only partially charged, it
is possible that the defroster will
automatically turn itself off. When
this happens, the indicator lamp
inside the switch starts blinking.
As soon as the battery has suffi­
cient voltage, the defroster auto­
matically turns itself back on.
