Front Differential Gear Oil (Cvt Models) And Rear Differential Gear Oil; Recommended Grade And Viscosity; Power Steering Fluid (Sti); Checking The Fluid Level - Subaru WRX-STI Owner's Manual

Front differential gear oil
(CVT models) and rear differ-
ential gear oil
There is no oil level gauge. To check the
differential gear oil level, we recommend
that you consult your SUBARU dealer.
& 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 F12-6.
CAUTION
Using a differential gear oil other
than the specified oil may cause a
decline in vehicle performance.

Power steering fluid (STI)

& 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 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 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. We recom-
mend that you consult your SUBARU
dealer for an inspection.
WARNING
Be careful not to burn yourself
because the fluid may be hot.
CAUTION
. When power steering fluid is
being added, use only clean fluid,
and be careful not to allow any
dirt into the tank. And never use
different brands together.
. Be careful not to spill power
steering fluid when adding it. If
power steering fluid touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
