Page: 48 / 113

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 min­
utes of operation. Heavy accumula­
tion of snow and ice should be
removed before activating the defros­
ter.
If several power consumers are
turned on simultaneously, or the bat­
tery is only partially charged, it is pos­
sible that the defroster will automati­
cally turn itself off. When this hap­
pens, the indicator lamp inside the
switch starts blinking. As soon as the
battery has sufficient voltage, the
defroster automatically turns itself
back on.
Rear Window Defroster
With engine running, press symbol
side of rocker switch to turn on, bot­
tom to turn off.
When activating the rear window
defroster, the indicator lamp in the
switch will come on.
