Remove the washer tank filler cap, then check the fluid
level indicated by the level gauge (attached to the in-
side of the cap). If the level is near the "Low" mark, add
fluid 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 water.
In areas where water freezes in winter, use an anti-
freeze type windshield washer fluid. SUBARU Wind-
shield Washer Fluid contains 58.5% methyl alcohol
and 41.5% surfactant, by volume. Its freezing temper-
ature varies according to how much it is diluted, as in-
dicated in the following table.
