3) Oil level
Remove the plug from the filler hole and
check the oil level. The oil level should be
kept even with the bottom of the filler hole. If the oil level is below the bottom edge of
the hole, add oil through the filler hole to
raise the level.
CAUTION
. Be careful not to spill rear differ-
ential gear oil when adding it. If
rear differential gear oil touches
the exhaust pipe, it may cause a
bad smell, smoke, and/or a fire. If
rear differential gear oil gets on
the exhaust pipe, be sure to wipe
it off.
. If the vehicle requires frequent
refilling, there may be an oil leak.
If you suspect a problem, have
the vehicle checked at your
SUBARU dealer.
& Recommended grade and viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together.
Oil grade: API classification GL-5

2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has
been run: Check that the oil level isbetween“HOT MIN ”and “HOT MAX ”on
the surface of the reservoir tank.
When the fluid is cool before the vehicle is
run: Check that the oil level is between“ COLD MIN ”and “COLD MAX ”on the
surface of the reservoir tank.
3. If the fluid level is lower than the
applicable “MIN ”line, add the recom-
mended fluid as necessary to bring the
level between the “MIN ”and “MAX ”line.
If the fluid level is extreme low, it may
indicate possible leakage. Consult your
SUBARU dealer for inspection.
& Recommended fluid
Use one of the following types of auto-
matic transmission fluid. –SUBARU ATF
– IDEMITSU ATF HP
–“ Dexron III ”Type Automatic Transmis-
sion Fluid Brake fluid &
Checking the fluid level
WARNING
. Never let brake fluid contact your
eyes because brake fluid can be
harmful to your eyes. If brake
fluid gets in your eyes, immedi-
ately flush them thoroughly with
clean water. For safety, when
performing this work, wearing
eye protection is advisable.
. Brake fluid absorbs moisture
from the air. Any absorbed moist-
ure can cause a dangerous loss
of braking performance.
. If the vehicle requires frequent
refilling, there may be a leak. If
you suspect a problem, have the
vehicle checked at your SUBARU
dealer.
CAUTION
. Never use different brands of
brake fluid together. Also, avoid
mixing DOT 3 and DOT 4 brake
fluids even if they are of the samebrand. .
When adding brake fluid, be care-
ful not to allow any dirt into the
reservoir.
. Never splash the brake fluid over
painted surfaces or rubber parts.
Alcohol contained in the brake
fluid may damage them.
. Be careful not to spill brake fluid
when adding it. If brake fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If brake fluid gets on the
exhaust pipe, be sure to wipe itoff.
Check the fluid level monthly.
