Manual transmission oil &Checking the oil level
NOTE 
For STI models, there is no transmis- 
sion oil level gauge. Consult your
SUBARU dealer to check the oil level.
Except STI
Check the oil level monthly. 
1. Park the vehicle on a level surface and 
stop the engine. 
2. Pull out the level gauge, wipe it clean, 
and insert it again.
1) Upper level 
2) Lower level
3. Pull out the level gauge again and 
check the oil level on it. If it is below the
lower level, add oil through the level
gauge hole to bring the level up to the
upper level.
CAUTION
Be careful not to spill manual trans- 
mission oil when adding it. If oil
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off. &
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 ”F 12-6.   
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. &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 ”F 12-6. Power steering fluid &
Checking the fluid level
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 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 extremely low, it may
indicate possible leakage. Consult your
SUBARU dealer for an inspection.
