Washer fluid level gauge

Remove the washer tank filler cap, then
check the fluid level indicated by the level
gauge (attached to the inside of the cap).
If the level is near the "Low" mark, add flu-
id until it reaches the "Hi" level on the level
gauge or the "Full" mark on the tank.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean wa-
ter.
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 temper-
ature varies according to how much it is di-
luted, as indicated in the following table.

Never use engine coolant as washer
fluid because it could cause paint
damage.
In order to prevent freezing of washer flu-

id, check the freezing temperatures in the
table above when adjusting the fluid con-
centration 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 tem-
perature, it may freeze and block the noz-
zles.
Adjust the washer fluid concentra-
tion appropriately for the outside
temperature. If the concentration is
