Automatic transmission fluid &Checking the fluid level
The automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid temperature.
Therefore, there are two different scales
for checking the level of hot fluid and cold
fluid on the level gauge.
Though the fluid level can be checked
without warming up the fluid on the“ COLD ”range, it is recommended to
check the fluid level when the fluid is at
operating temperature. ! Checking the fluid level when the
fluid is hot
1. Drive the vehicle several miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 158
to 176 8F (70 to 80 8C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the select lever in each
position. Then shift it in the “P ” position,
and run the engine at idling speed.
1) Yellow handle
1) HOT range
2) COLD range
3) Full level
4) Low level
4. Pull out the level gauge and check the fluid level on the gauge. If it is below the
low level on the
“HOT ”range, add the
recommended automatic transmission
fluid up to the full level.
NOTE
Do not fill the automatic transmission
fluid over the full level. ! Checking the fluid level when the
fluid is cold
When the fluid level has to be checked
without time to warm up the automatic
transmission, check that the fluid level is
between the low level and full level on the“ COLD ”range. If it is below that range,
add fluid up to the full level. Be careful not
to overfill.
CAUTION
Be careful not to spill automatic
transmission fluid when adding it.
If automatic transmission fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If automatic transmission fluid
gets on the exhaust pipe, be sure to
wipe it off.

&Recommended fluid
Refer to “Fluids ”F 12-9.
NOTE
Using any non-specified type of auto-
matic transmission fluid could result in
damage inside the transmission. When
replacing the automatic transmission
fluid, be sure to use the specified type. 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) Full level
2) Low level
3. Pull out the level gauge again and
check the oil level on it. If it is below the
low level, add oil to bring the level up to
the full 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, consult your SUBARU dealer forinspection. &
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 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.
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.
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.
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.
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. Never use
different brands of fluids to-
gether.
. 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
power steering fluid gets on the
exhaust pipe, be sure to wipe itoff.
& Recommended fluid
Refer to “Fluids ”F 12-9. Brake fluid &
Checking the fluid level
1) “MAX ”level mark
2) “MIN ”level mark
Check the fluid level monthly.
Check the fluid level on the outside of the
reservoir. If the level is below “MIN ”, add
the recommended brake fluid to “MAX ”.
Use only brake fluid from a sealed
container.
WARNING
. Never let brake fluid contact your
eyes because brake fluid can be
harmful to your eyes. If brake
