tempting to operate the wiper with the blades
frozen to the window glass could cause not
only the wiper blades to be damaged but also
the wiper motor to burn out. If the wiper blade
is frozen to the window glass, be sure to oper-
ate the defroster, windshield wiper deicer (if
equipped) or rear window defogger before turn-
ing on the wiper.
If the wipers stop during operation because
of ice or some other obstruction on the window,
the wiper motor could burn out even if the wiper
switch is turned off. If this occurs, promptly
stop the vehicle in a safe place, turn the ignition
switch to the “LOCK” position and clean the
window glass to allow proper wiper operation.
Use clean water if windshield washer fluid is
unavailable. In areas where water freezes in
winter, use SUBARU Windshield Washer Fluid
or the equivalent. (See the “Windshield washer
fluid” section in chapter 11.)
Also, when driving the vehicle when there are
freezing temperatures, use non-freezing type
wiper blades.
Do not clean the wiper blades with gasoline
or a solvent, such as paint thinner or benzene.
This will cause deterioration of the wiper
blades.
NOTE
The wiper operates only when the ignition
switch is in the “ON” or “ACC” position.
Clean your wiper blades and window glass peri-
odically with a washer solution to prevent streak-
ing, and to remove accumulations of road salt or
road film. Keep the washer button depressed at
least for 1 second so that washer solution will be
sprinkled all over the windshield or rear window.
Grease, wax, insects or other material on the
windshield or the wiper blade results in jerky wip-
er operation and streaking on the glass. If you can-
not remove those streaks after operating the
washer or if the wiper operation is jerky, clean the
outer surface of the windshield or rear window
and the wiper blades using a sponge or soft cloth
with a neutral detergent or mild-abrasive cleaner.
After cleaning, rinse the window glass and wiper
blades with clean water. The glass is clean if no
beads form on the glass when you rinse with wa-
ter.
If you cannot eliminate the streaking even after
following this procedure, replace the wiper blades
with new ones. Refer to the “Replacement of wiper
