NOTEDue to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the ex-
haust system for a short time after the
engine has been shut off. This sound is
normal.
Catalytic converterTurbo model
Non-turbo model
The catalytic converter is installed in the
exhaust system. It serves as catalyst to
reduce HC, CO and NOx in exhaust gas-
es, thus providing cleaner exhaust.
To avoid damage to the catalytic convert-
er:
yUse only unleaded fuel. Even a small
amount of leaded fuel will damage the cat-
alytic converter.
y Never start the engine by pushing or
pulling the vehicle.
y Avoid racing the engine.
y Never turn off the ignition switch while
the vehicle is moving.
y Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer.
y Do not apply undercoating or rust pre-
vention treatment to the heat shield of cat-
alytic converter and the exhaust system.
y If at any time you suspect that ex-
haust fumes are entering the vehi-
cle, have the problem checked
and corrected as soon as possi-
ble. If you must drive under these
conditions, drive only with all win-
dows fully open.yKeep the rear gate closed while
driving to prevent exhaust gas
from entering the vehicle.

yAvoid fire hazards. Do not drive or
park the vehicle anywhere near
flammable materials (e.g. grass,
paper, rags or leaves), because
the catalytic converter operates at
very high temperatures.

Driving tips
tight turn, the trailer could hit your vehicle.
yCrosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and slow down im-
mediately but gradually.
y When passing other vehicles, consider-
able distance is required because of the
added weight and length caused by at-
taching the trailer to your vehicle.1) Left turn
2) Right turny Backing up with a trailer is difficult and
takes practice. When backing up with a
trailer, never accelerate or steer rapidly.
When turning back, grip the bottom of the steering wheel with one hand and turn it to
the left for a left turn, and turn it to the right
for a right turn.
y
If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed im-
mediately by the nearest SUBARU dealer.
T Driving on grades
y Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’s brakes. Do not
make sudden downshifts.
y When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating.
y When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT vehicles) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3. y
If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission
fluid to overheat.
y If your vehicle has an automatic trans-
mission, place the selector lever as fol-
lows:
Uphill slopes: “D” position
Downhill slopes: A low-speed gear posi-
tion to use engine braking
T Parking on a grade
Always block the wheels under both vehi-
cle and trailer when parking. Apply the
parking brake firmly. You should not park
on a hill or slope. But if parking on a hill or
slope cannot be avoided, you should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P” (automatic transmis-1 2

14.Store the flat tire in the spare tire com-
partment.
Put the spacer and tighten the attaching
bolt firmly.
Also store the jack and wheel nut wrench
in their storage locations.
Jump starting
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables.
Never place a tire or tire changing
tools in the passenger compartment
after changing wheels. In a sudden
stop or collisions, loose equipment
could strike occupants and cause
injury. Store the tire and all tools in
the proper place.

yBattery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or the ve-
hicle.
If battery fluid gets on you, thor-
oughly flush the exposed area
with water immediately. Get medi-
cal help if the fluid has entered
your eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water, and
obtain immediate medical help.
Keep everyone including children
away from the battery.yThe gas generated by a battery ex-
plodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting.yNever attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst or
explode.
yWhenever working on or around a
battery, always wear suitable eye
protectors, and remove metal ob-
jects such as rings, bands or oth-
er metal jewelry.yBe sure the jumper cables and
clamps on them do not have loose
or missing insulation.
Do not jump start unless cables in
suitable condition are available.yA running engine can be danger-
ous. Keep your fingers, hands,
clothing, hair and tools away from
the cooling fan, belts and any oth-
er moving engine parts. Remov-
ing rings, watches and ties is ad-
visable.yJump starting is dangerous if it is
done incorrectly. If you are unsure
about the proper procedure for
jump starting, consult a compe-
tent mechanic.

Appearance care
other parts of the vehicle may be dry.
4. High temperatures will cause corrosion
to parts of the vehicle which cannot dry
quickly due to lack of proper ventilation.„To help prevent corrosionWash the vehicle regularly to prevent cor-
rosion of the body and suspension com-
ponents. Also, wash the vehicle promptly
after driving on any of the following surfac-
es:
yroads that have been salted to prevent
them from freezing in winter
y mud, sand, or gravel
y coastal roads
After the winter has ended, it is recom-
mended that the underbody be given a
very thorough washing.
Before the beginning of winter, check the
condition of underbody components, such
as the exhaust system, fuel and brake
lines, brake cables, suspension, steering
system, floor pan, and fenders. If any of
them are found to be rusted, they should
be given an appropriate rust prevention
treatment or should be replaced. Contact
your SUBARU dealer to perform this kind
of maintenance and treatment if you need
assistance.
Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water
and dirt accumulation under the floor mats
because that could cause corrosion. Oc-
casionally check under the mats to make
sure the area is dry.
Keep your garage dry. Do not park your
vehicle in a damp, poorly ventilated ga-
rage. In such a garage, corrosion can be
caused by dampness. If you wash the ve-
hicle in the garage or put the vehicle into
the garage when wet or covered with
snow, that can cause dampness.
If your vehicle is operated in cold weather
and/or in areas where road salts and other
corrosive materials are used, the door
hinges and locks, trunk lid lock, and hood
latch should be inspected and lubricated
periodically.
Cleaning the interiorUse a soft, damp cloth to clean the climate
control panel, audio equipment, instru-
ment panel, center console, combination
meter panel, and switches. (Do not use or-
ganic solvents.)„
Seat fabricRemove loose dirt, dust or debris with a
vacuum cleaner. If the dirt is caked on the
fabric or hard to remove with a vacuum
cleaner, use a soft blush then vacuum it.
Wipe the fabric surface with a tightly
wrung cloth and dry the seat fabric thor-
oughly. If the fabric is still dirty, wipe using
a solution of mild soap and lukewarm wa-
ter then dry thoroughly.
If the stain does not come out, try a com-
mercially-available fabric cleaner. Use the
cleaner on a hidden place and make sure
it does not affect the fabric adversely. Use
the cleaner according to its instructions.NOTEWhen cleaning the seat, do not use
benzine, paint thinner, or any similar
materials.

TChanging the coolant
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant is
replaced.
Change the engine coolant and add gen-
uine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule.
1. Remove the under cover.
2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely.
4. Install the under cover.Non-turbo models
1) Filler neck
2) Fill up to this level Turbo models
1) Filler neck
2) Fill up to this level
5. Slowly pour the coolant and fill up to
just below the filler neck, allowing enough
room to add genuine Subaru cooling sys-
tem conditioner in the radiator. Add genu-
ine Subaru cooling system conditioner un-
til the coolant level reaches the filler neck.
Do not pour the coolant too quickly, as this
may lead to insufficient air bleeding and
trapped air in the system.
B00019
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.

Air cleaner elementThe air cleaner element functions as a fil-
ter screen. When the element is perforat-
ed or removed, engine wear will be exces-
sive and engine life shortened.
The air cleaner element is a viscous type.
It is unnecessary to clean or wash the ele-
ment.„Replacing the air cleaner ele-
mentReplace the air cleaner element according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. Under
extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts. T
Non-turbo models
1. Unsnap the two clamps holding the air
cleaner case cover.
2. Push the air cleaner case cover in the
direction of the arrow shown in the draw- ing.
1) Air cleaner case cover
2) Air cleaner element3. Open the air cleaner case cover and
remove the air cleaner element.
4. Clean the inside of the air cleaner cov-
er and case with a damp cloth and install
a new air cleaner element.
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters in-
take air but also stops flames if the
engine backfires. If the air cleaner
element is not installed when the en-
gine backfires, you could be burned.

Drive belts1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulleyThe alternator, power steering pump, and
air conditioner compressor depend on
drive belts. Satisfactory performance re-
quires that belt tension be correct.
To check belt tension, 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. If a belt is loose,
cracked, or worn, contact your SUBARU
dealer.
