Engine Oil
7) Fill engine oil through the filler pipe up to center
between upper lever and lower level. Make sure
that the vehicle is placed level when checking oil
level. Use engine oil of proper quality and viscosity,
selected in accordance with the table in figure.
Recommended oil
API classification SL, SJ with the “Energy
Conserving” logo is printed, or SH (if you
cannot obtain the oil with SL, SJ or SH
grades, you may use SG, SF grades “ENER-
GY CONSERVING” oil.)
ACEA specification, A1, A2 or A3
CCMC specification, G4 or G5
New API certification mark (Star burst mark)
label is on the container.

Upper level
Approx. 4.02 (4.2 US qt, 3.5 Imp qt)
Lower level
Approx. 3.02 (3.2 US qt, 2.6 Imp qt)
The proper viscosity helps vehicle get good cold
and hot starting by reducing viscous friction and
thus increasing cranking speed.
CAUTION:
When replenishing oil, it does not matter if the
oil to be added is a different brand from that in
the engine; however, use oil having the API
classification and SAE viscosity No. designat-
ed by SUBARU.
NOTE:
If the vehicle is used in areas with very high temper-
atures or for other heavy duty applications, the fol-
lowing viscosity oils may be used: API
classification: SL, SJ or SH
SAE Viscosity No. : 30, 40, 10W-50, 20W-40, 20W-
50.
8) Close the engine oil filler cap.
9) Start the engine and warm it up for a time.
10) After the engine stops, recheck the oil level.
B: INSPECTION
1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and in the
proper orientation.
4) Remove it again and note the reading. If the en-
gine oil level is below the “L” line, add oil to bring
the level up to the “F” line.
5) After turning off the engine, wait a few minutes
for the oil to drain back into oil pan before checking
the level.
6) Just after driving or while the engine is warm, en-
gine oil level may show in the range between the
“F” line and the notch mark. This is caused by ther-
mal expansion of the engine oil.
7) To prevent overfilling the engine oil, do not add
oil above the “F” line when the engine is cold.

A: REPLACEMENT
1. REPLACEMENT OF ENGINE COOLANT
WARNING:
The radiator is of the pressurized type. Do not
attempt to open the radiator cap immediately
after the engine has been stopped.
1) Lift-up the vehicle.
2) Remove the under cover.
3) Place a container under drain pipe.
4) Loosen and remove the drain cock to drain en-
gine coolant into container.
5) For quick draining, open the radiator cap.
CAUTION:
Be careful not to spill coolant on the floor.
6) Drain the coolant from reservoir tank.
7) Tighten the radiator drain cock securely after
draining coolant.
8) Slowly pour the engine coolant from radiator fill-
er port to neck of filler, then pour into reservoir tank
up to “FULL” level.

2.5 L MT model:
Approx. 6.92 (7.3 US qt, 6.1 Imp qt)NOTE:
The SUBARU Genuine Coolant containing anti-
freeze and anti-rust agents is especially made for
SUBARU engine, which has an aluminum crank-
case. Always use SUBARU Genuine Coolant,
since other coolant may cause corrosion.
9) Securely install the radiator cap.
10) Run the engine for more than 5 minutes at
2,000 to 3,000 rpm. (Run the engine until radiator
becomes hot in order to purge the air trapped in
cooling system.)
11) Stop the engine and wait until coolant temper-
ature lowers. Then open the radiator cap to check
coolant level and add coolant up to radiator filler
neck. Next, add coolant into reservoir tank up to
“FULL” level.
12) After adding coolant, securely install the radia-
tor and reservoir tank caps.

ATF
16.ATF
A: INSPECTION
CAUTION:
The level of ATF varies with fluid temperature.
Pay attention to the fluid temperature when
checking ATF level.
1) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 70 — 80°C (158
— 176°F) on Subaru Select Monitor. 4AT(H4SO)-18, READ CURRENT DATA, OPERA-
TION, Subaru Select Monitor.>
2) Make sure the vehicle is level.
3) After selecting all positions (P, R, N, D, 3, 2, 1),
set the select lever in “P” range. Measure the ATF
level with the engine idling for one or two minutes.
4) Make sure that ATF level is above the center of
upper and lower level.
NOTE:
When the transmission is hot, the level should be
above the center of upper and lower marks, and
when it is cold, the level should be found below the
center of these two marks.
5) If the ATF level is below the center between up-
per and lower marks, add the recommended ATF
until the ATF level is found above the center be-
tween upper and lower marks.
CAUTION:
 Use care not to exceed the upper limit level.
 Remember that the addition of ATF to the up-
per limit mark when the transmission is cold
will result in overfilling of ATF, causing a trans-
mission failure.
6) Check ATF level after raising ATF temperature
to 70 — 80°C (158 — 176°F) by running the vehicle
or by idling the engine again.7) Check the ATF for leaks.
Check for leaks in the transmission. If there are
leaks, it is necessary to repair or replace gasket, oil
seals, plugs or other parts.
B: REPLACEMENT
1. AUTOMATIC TRANSMISSION FLUID
1) Drain the ATF by removing drain plug.
NOTE:
Before starting work, cool off ATF well.
2) Replace the gasket with a new one, and then
tighten the specified torque.
Tightening torque:
25 N·m (2.5 kgf-m, 18.1 ft-lb)
3) Fill ATF up to the middle of the “COLD” side on
level gauge by using the gauge hole.
Recommended fluid:
Dexron III type automatic transmission fluid

(2) Retighten the adjusting screw to 7.4 N·m
(0.75 kgf-m, 5.4 ft-lb) and back off 25°.
(3) Apply Liquid gasket to at least 1/3 of entire
perimeter of adjusting screw thread.
(4) Install the lock nut. While holding the adjust-
ing screw with a wrench, tighten the lock nut us-
ing ST.

Tightening torque (Lock nut):
39 N·m (4.0 kgf-m, 29 ft-lb)
Hold the adjusting screw with a wrench to pre-
vent it from turning it, while tightening the lock
nut.
4. TIE-ROD
1) Check the tie-rod and tie-rod ends for bends,
scratches or other damage.
2) Check the connections of knuckle ball joints for
play, inspect for damage on dust seals, and check
free play of ball studs. If the castle nut is loose, re-
tighten it to the specified torque, then tighten further
up to 60° until the cotter pin hole is aligned.
Tightening torque:
27 N·m (2.75 kgf-m, 19.9 ft-lb)3) Check the lock nut on tie-rod end for tightness. If
it is loose, retighten it to the specified torque.
Tightening torque:
83 N·m (8.5 kgf-m, 61.5 ft-lb)
5. POWER STEERING FLUID LEVEL
NOTE:
 Check at power steering fluid temperature 20°C
(68°F); read the fluid level on the “COLD” side.
 Check at power steering fluid temperature 80°C
(176°F); read the fluid level on the “HOT” side.
1) Place the vehicle with engine stopped on a flat
and level surface.
2) Check the fluid level using the scale on the out-
side of reservoir tank (A). If the level is below “MIN”
(B), add fluid to bring it up to “MAX” (C).
NOTE:
If the fluid level is at “MAX” level or above, drain flu-
id to keep the level in specified range of indicator by
using a syringe or the like.
Recommended fluid:
Dexron III
Fluid capacity:
0.72 (0.7 US qt, 0.6 Imp qt)
6. POWER STEERING FLUID FOR LEAKS
Inspect the underside of oil pump and gearbox for
power steering system, hoses, piping and their
couplings for fluid leaks.
If fluid leaks are found, correct them by retightening
their fitting bolts (or nuts) and/or replacing their
parts.
CAUTION:
 Wipe the leakage fluid off after correcting flu-
id leaks, or a wrong diagnosis is taken later.
 Also pay attention to clearances between
hoses (or pipings) and other parts when in-
specting fluid leaks.
