Maintenance and service/Replacement of wiper blades
Remove the washer tank filler cap, then
add windshield washer fluid until it
reaches the FULL mark on the tank.
& Windshield washer fluid
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table.
Washer Fluid
Concentration Temperature
−128C (10.48F)
30%
−208C (−48F)
50%
−458C (−498F)
100%
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block the
nozzles.
CAUTION
Adjust the washer fluid concentra-
tion appropriately for the outside
temperature. If the concentration is
inappropriate, sprayed washer fluid
may freeze on the windshield and
obstruct your view, and the fluid
may freeze in the reservoir tank.

Replacement of wiper blades

Freezing
Grease, wax, insects, or other material on
the windshield or the wiper blade results in
jerky wiper operation and streaking on the
glass. If you cannot remove the streaks
after operating the windshield 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 windshield and wiper
blades with clean water. The windshield is
clean if beads do not form when you rinse
the windshield with water.
. Do not clean the wiper blades
with fuel or a solvent, such as
paint thinner or benzine. This will
cause deterioration of the wiper
blades.
. While removing the wiper blades
from the wiper arms, do not
return the wiper arms to the
original positions. Otherwise,
the windshield surface may be
scratched.
. When returning the raised wiper
arms to the original positions,
CAUTION
