the spark plugs replaced by your
SUBARU dealer.
The spark plugs should be replaced ac-
cording to the maintenance schedule in
the “Warranty and Maintenance Booklet”. „

Drive belts
The alternator, power steering pump, and
air conditioner compressor depend on
drive belts. Satisfactory performance re-
quires that belt tension be correct. „2.5-liter models
1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulley in (mm)
To check belt tensi on, place a straight-
edge (ruler) across two adjacent pulleys
and apply a force of 22 lbs (98 N, 10 kg)
midway between the pulleys by using a
spring scale. Belt deflection should be the
amount specified. „ 3.0-liter models
It is unnecessary to check belt tension pe-
riodically because your engine is
equipped with an autom atic belt tension
adjuster. However, replacement of the
belt should be done according to the
maintenance schedule in the “Warranty
and Maintenance Booklet”. Consult your
SUBARU dealer for replacement.
If a belt is loose, cr acked, or worn, contact
your SUBARU dealer.Manual transmission oil „ Checking the oil level

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. T Checking the fluid level when the
fluid is hot
Check the fluid level monthly.
1. Drive the vehicle se veral 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. 4-speed automatic transmission
1) Yellow handle
5-speed automatic transmission
1) Yellow handle1) HOT range
2) COLD range
3) Upper level
4) 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. T 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.1

Power steering fluid „Checking the fluid level
The power steering fluid expands greatly
as its temperature rises; the fluid level dif-
fers according to fluid temperature. There-
fore, 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 be-
tween “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 sur-
face of the reservoir tank.
3. If the fluid level is lower than the appli-
cable “MIN” line, add the recommended
fluid as necessary to bring the level be-
tween the “MIN” and “MAX” line. If the fluid level is extreme low, it may indi-
cate possible leakage. Consult your
SUBARU dealer for inspection. „
