2011 SUBARU IMPREZA WRX transmission oil

&Recommended fluid
Refer to “Fluids ”F 12-9.
NOTE
For optimum transmission perfor-
mance, only use the automatic trans-
mission fluid that is recommended and
provided by SUBARU.
If the recommended automatic trans-
mission fluid is unavailable, Dexron III
may be temporarily used. If the Dexron
III is used continuously there will be a
noticeable increase in the vibration and
noise from the automatic transmission. Front differential gear oil (AT models) &
Checking the oil level
1) Yellow handle
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 to bring the level up to
the upper level.
CAUTION
Be careful not to spill front differ-
ential gear 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. Maintenance and service

&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, front differential
and rear differential gear oil ”F 12-8. 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, front differential
and rear differential gear oil ”F 12-8. 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.
