11-20 Maintenance and service
Automatic transmission fluid
Checking the fluid level
The automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid tempera-
ture. Therefore, there are two different
scales for checking the level of hot fluid
and cold fluid on the dipstick.
Though the fluid level can be checked
without warming up the fluid on the“COLD ” range, we recommend checking
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 F (70 to 80 C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the selector lever in each po-
sition. Then shift it in the “P ” position, and
run the engine at idling speed.
1) Yellow handle
A) HOT range
B) COLD range
1) Upper level
2) Lower level
4. Pull out the dipstick and check the fluid
level on the gauge. If it is below the lower
level on the “HOT ” range, add the recom-
mended automatic transmission fluid up to
the upper 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 to see that the fluid
level is between the lower level and upper
level on the “COLD ” range. If it is below
that range, add fluid up to the upper level.
Be careful not to overfill.

Be careful not to spill automatic
transmission fluid when adding it. If
automatic transmission fluid touch-
es the exhaust pipe, it may cause a
bad smell, smoke, and/or a fire. If au-
tomatic transmission fluid gets on
the exhaust pipe, be sure to wipe it
off.

Recommended fluid
Use one of the following types of automat-
ic transmission fluid.
Genuine Subaru Automatic Transmis-
sion Fluid Type-HP
IDEMITSU ATF HP
Castrol Transmax J
Pennzoil ATF-J*
* Available only in the USA (except
Alaska and Hawaii)
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 a fluid of the types
specified above.
Front differential gear oil (AT
vehicles)
Checking the oil level
1) Yellow handle
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again.
1) Upper level
2) Lower level
3. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.

Be careful not to spill front differen-
tial 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.
