Instruments and controls
To turn on the defogger, push the button. To turn it off,
push the button again.
The indicator light located on the button lights up while
the rear window defogger is operating.
Your SUBARU dealer can set your rear window defog-
ger for continuous operation. Contact your SUBARU
dealer for details.
Once the rear window defogger has been set for con-
tinuous operation, the rear window defogger repeated-
ly operates for 15 minutes, stops for two minutes, and
again operates for 15 minutes. If the battery voltage
drops below the permissible level, continuous opera-
tion is canceled and operation stops as described be-
low.
"
If the battery voltage drops below the permissible
level within 15 minutes of depression of the button,
continuous operation is canceled and the rear window
defogger stops operating 15 minutes later.
"
If the battery voltage drops below the permissible
level after the rear window defogger has, following de-
pression of the button, operated for 15 minutes,
stopped operating for two minutes, and started operat-
ing again, the rear window defogger immediately
stops operating.
" Do not use sharp instruments or window
cleaner containing abrasives to clean the inner
surface of the rear window. They may damage
the conductors printed on the window.
"
To prevent the battery from being dis-
charged, do not operate the defogger continu-
ously for any longer than necessary.
NOTE
If your vehicle is equipped with the outside mirror
defogger, the outside mirror defogger operates
while the rear window defogger is operating.
