Rear differential gear oil
There is no rear differential gear oil level
gauge. To check the rear differential gear
oil level, we recommend that you consult
your SUBARU dealer for inspection.

Power steering fluid
& Checking the fluid level

& Recommended grade and
viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
“Manual transmission and rear differential
gear oil” F12-6.
The power steering fluid expands greatly
as its temperature rises; the fluid level
differs according to fluid temperature.
Therefore, the reservoir tank has two
different checking ranges for hot and cold
fluids.
Check the power steering fluid level
monthly.
1. Park the vehicle on a level surface,
and stop the engine.

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 is
between “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 recommended fluid as necessary to bring the
level between the “MIN” and “MAX” line.
If the fluid level is extremely low, it may
indicate possible leakage. Consult your
SUBARU dealer for an inspection.
