the instrument panel.

Heated Rear Window

Turn key in steering lock to posi­
tion " 2" .
When the rear window heater is
turned on, the white indicator lamp in
the switch comes on.
A heavy load is imposed on the
battery due to the high power
requirement. For this reason, switch
off the heated rear window as soon as
it is demisted or defrosted. It is shut
off automatically after a maximum of
30 minutes. Always remove heavy
layers of ice and snow first.
