1. Note
A: NOTE
This is information that can improve efficiency of
maintenance and assure sound work.
1. FASTENER NOTICE
Fasteners are used to prevent parts from damage
and dislocation due to looseness. Fasteners must
be tightened to the specified torque.
Do not apply paint, lubricant, rust retardant, or oth-
er substances to the surface around bolts, fasten-
ers, etc. Doing so will make it difficult to obtain the
correct torque and result in looseness and other
problems.
2. STATIC ELECTRICITY DAMAGE
Do not touch the control unit, connectors, logic
boards, and other such parts when there is a risk of
static electricity. Always use a static electricity pre-
vention cord or touch grounded metal before con-
ducting work.
3. BATTERY
When removing the battery cables, always be sure
to turn the ignition switch off to prevent electrical
damage to the control unit from rush current.
4. SERVICE PARTS
Use authentic service parts for maximum perfor-
mance and maintenance, when conducting repairs.
Subaru/FHI will not be responsible for poor perfor-
mance resulting from the use of parts not specified
by a genuine dealer.
5. PROTECTING VEHICLE UNDER MAIN-
TENANCE
Make sure to attach the fender cover, seat covers,
etc. before work.
6. ENSURING SAFETY DURING WORK
When working in a group of two or more, perform
the work with calling each other to ensure mutual
safety.

7. LIFTS AND JACKS
When using a lift or jack to raise a vehicle, always follow instructions concerning jack-up points and weight
limits to prevent the vehicle from falling, which could result in injury. Be especially careful to make sure the
vehicle is balanced before raising it.
Be sure to set the wheel stoppers when jacking-up only the front or rear of the vehicle.

PRE-DELIVERY INSPECTION
Pre-delivery Inspection
1. Pre-delivery Inspection
A: GENERAL
The purposes of the pre-delivery inspection (PDI)
are as follows.
 Remove the additional parts used for ensuring
the vehicle quality during transportation and restore
the vehicle to its normal state.
 Check if the vehicle before delivery is in a normal
state.
 Check for any damage or missing parts that may
have taken place during transportation or storage.
 Make sure to deliver a complete vehicle to the
customer.
Because of the above reasons, all SUBARU distrib-
utor service must always carry out the PDIs before
delivering a vehicle.
In addition, all SUBARU distributor service and PDI
centers must check the status of every vehicle re-
ceived to identify who is responsible for any possi-
ble defects.

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.
Coolant capacity (fill up to “FULL” level)
2.0 L Non-turbo AT model:
Approx. 6.52 (6.9 US qt, 5.7 Imp qt)

Approx. 6.82 (7.2 US qt, 6.0 Imp qt)
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.

4. WHEEL ALIGNMENT OF FRONT SUS-
PENSION
1) Check the alignment of front suspension to en-
sure that following items conform to standard val-
ues.
 Toe-in
 Camber angle
 Caster angle
 Steering angle

2) When the caster angle does not conform to ref-
erence, visually inspect the following components
and replace deformed parts.
 Suspension components [Strut assembly, cross-
member, transverse link, etc.]
 Body parts to which suspensions are installed.
3) When the toe-in and camber are out of standard
value, adjust them so that they conform to respec-
tive service standard. WHEEL TOE-IN, INSPECTION, Wheel Align-
ment.> Wheel Alignment.>
4) When the right-and-left turning angles of tire are
out of standard, adjust to standard value. FS-10, STEERING ANGLE, INSPECTION, Wheel

5. WHEEL ALIGNMENT OF REAR SUS-
PENSION
1) Check the alignment of rear suspension to en-
sure that following items are within standard val-
ues.
 Toe-in
 Camber angle
 Thrust angle

2) When the camber angle does not conform to ref-
erence, visually inspect parts listed below. If defor-
mation is observed, replace the damaged parts.
 Suspension components [Shock absorber, front
lateral links, rear lateral links, trailing link, etc.]
 Body parts to which suspensions are installed.
3) When the toe-in and thrust angle are out of stan-
dard value, adjust them so that they conform to re-
spective service standard. WHEEL TOE-IN, INSPECTION, Wheel Align-
ment.> SPECTION, Wheel Alignment.>
6. OIL LEAKAGE OF STRUT
Visually inspect the front strut and rear strut for oil
leakage as instructed. If oil leakage reaches under
spring seat lower portion, replace the front strut and
rear strut.
7. TIGHTNESS OF BOLTS AND NUTS
Check the bolts and nuts shown in the figure for
looseness. Retighten the bolts and nuts to speci-
fied torque. If the self-lock nuts and bolts are re-
moved, replace them with new ones.
Front suspension: tion.>
Rear suspension: tion.>
8. DAMAGE TO SUSPENSION PARTS
Check the following parts and the fastening portion
of the vehicle body for deformation or excessive
rusting which impairs the suspension. Remove the
contaminations on spring seat lower portion with
care because dirt, sand, etc. tend to accumulate on
it. If necessary, replace the damaged parts with
new ones. If minor rust formation, pitting, etc. are
noted, remove the rust and apply remedial anti-cor-
rosion measures.

 In the district where salt is sprayed to melt snow
on a road in winter, check suspension parts for
damage caused by rust every 12 months after
lapse of 60 months. Take rust prevention measure
as required.

ing when installing hoses.
8. POWER STEERING PIPES FOR DAM-
AGE
Check the power steering pipes for corrosion and
damage.
Replace the pipes with a new one if necessary.
9. GEARBOX BOOTS

correct the defects if necessary.
1) (A) and (B) positions of gearbox boot are fitted
correspondingly in (A) and (C) grooves of gearbox
and the rod (C).
2) Clips are fitted outside of (A) and (B) positions of
boot.
3) Boot does not have crack and hole.
NOTE:

twist of it produced by adjustment of toe-in, etc.
Apply grease to the groove (C).
10.FITTING BOLTS AND NUTS
Inspect the fitting bolts and nuts of oil pump and
bracket for looseness, and retighten them if neces-
sary.
NOTE:
Inspect or retighten them when engine is cold.

FUEL INJECTION (FUEL SYSTEM)
Fuel System Trouble in General
29.Fuel System Trouble in General
A: INSPECTION
NOTE:
 When the vehicle is left unattended for an ex-
tended period of time, water may accumulate in the
fuel tank.
To prevent water condensation.
(1) Top off the fuel tank or drain the fuel com-
pletely.
(2) Drain the water condensation from the fuel
filter.
 Refilling the fuel tank.
Refill the fuel tank while there is still some fuel left in
the tank.
 Protecting the fuel system against freezing and
water condensation.
(3) Cold areas :
In snow-covered areas, mountainous areas, ski-
ing areas, etc. where ambient temperatures
drop below 0°C (32°F) throughout the winter
season, use an anti-freeze solution in the fuel
tank. Refueling will also complement the effect
of anti-freeze solution each time the fuel leveldrops to about one-half. After the winter season,
drain the water which may have accumulated in
the fuel filter and fuel tank in the manner same
as that described under “Affected areas” below.
(4) Affected areas :
When the water condensation is notched in the
fuel filter, drain the water from both the fuel filter
and fuel tank or use a water removing agent (or
anti-freeze solution) in the fuel tank.
 Observe the instructions, notes, etc., indicated
on the label affixed to the anti-freeze solution (wa-
ter removing agent) container before use.
