erative. NEVER use a circuit
tester for this wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer.
NOTE
SUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.
&Before checking or servicing
in the engine compartment
WARNING
.Always stop the engine and apply
the parking brake firmly to pre-
vent the vehicle from moving.
.Always let the engine cool down.
Engine parts become very hotwhen the engine is running and
remain hot for some time after
the engine has stopped.
.Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
.When the ignition switch is in the
“ON”position, the cooling fan
may operate suddenly even
when the engine is stopped. If
your body or clothes come into
contact with a rotating fan, that
could result in serious injury. To
avoid risk of injury, perform the
following precautions.
–Models with push-button start
system:
Always turn the push-button
ignition switch to the“OFF”
position and confirm that the
operation indicator on the
switch is turned off. Then take
the access key out from the
vehicle.
–Models without push-button
start system:
Always remove the key from
the ignition switch.
.Before performing any servicing
on a vehicle equipped with aremote engine start system (a
dealer option), temporarily place
the remote engine start system in
service mode to prevent it from
unexpectedly starting the engine.
&When checking or servicing
in the engine compartment
CAUTION
.Do not contact the drive belt
cover while checking the compo-
nents in the engine compart-
ment. Doing so may cause your
hand to slip off the cover and
result in an unexpected injury.
.Do not touch the oil filter until the
11-4

engine has cooled down comple-
tely. Doing so may result in a
burn or other injury. Note that the
oil filter becomes very hot when
the engine is running and re-
mains hot for some time after
the engine has stopped.
&When checking or servicing
in the engine compartment
while the engine is running
WARNING
A running engine can be dangerous.
Keep your fingers, hands, clothing,
hair and tools away from the cooling
fan, drive belt and any other moving
engine parts. Removing rings,
watches and ties is advisable.
Engine hood
CAUTION
.When you open the engine hood,
do not stand the wiper blades up.
Furthermore, while the hood is
open, do not operate the wind-
shield wipers. Doing so could
result in damage to the engine
hood and wiper blades.
.Be extremely careful not to catch
fingers or other objects when
closing the engine hood.
.Do not push the hood forcibly to
close it. It could deform the
metal.
.Be extremely careful opening the
engine hood when the wind is
strong. The engine hood could
close suddenly, possibly causing
injuries from slamming.
.Do not install accessories other
than genuine SUBARU parts to
the engine hood. If the engine
hood becomes too heavy, the
stay may not be able to support
holding it open.To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
position.
2. Pull the hood release knob under the
instrument panel.

3. Release the secondary hood release
by moving the lever between the front
grille and the hood toward the left.
4. Lift up the hood, release the hood prop
from its retainer and put the end of the
hood prop into the slot in the hood.
To close the hood:
1. Lift the hood slightly and remove the
hood prop from the slot in the hood and
return the prop to its retainer.
2. Lower the hood to a height of approxi-
mately 5.9 in (15 cm) above its closed
position and then let it drop.
3. After closing the hood, be sure the
hood is securely locked.
If this does not close the hood, release it
from a slightly higher position.
WARNING
Always check that the hood is
properly locked before you start
driving. If it is not, it might fly open
while the vehicle is moving and
block your view, which may cause
an accident and serious bodily in-
jury.

Maintenance and service/Engine oil
Engine oil
CAUTION
.If the level gauge cannot be
pulled out easily, twist the level
gauge right and left, then gently
pull it out. Otherwise, you may be
injured accidentally straining
yourself.
.Use only engine oil with the
recommended grade and vis-
cosity.
.Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
&Engine oil consumption
Some engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the following conditions, oil
consumption can be increased and thus
require refilling between maintenance
intervals:
.When the engine is new and within thebreak-in period
.When the engine oil is of lower quality
.When the incorrect oil viscosity is used
.When engine braking is employed
(repeatedly)
.When the engine is operated at high
engine speeds (for extended periods of
time)
.When the engine is operated under
heavy loads (for extended periods of time)
.When towing a trailer
.When the engine idles for extended
periods of time
.When the vehicle is operated in stop
and go and/or heavy traffic situations
.When the vehicle is used under severe
thermal conditions
.When the vehicle accelerates and
decelerates frequently
Under these or similar conditions, you
should check your oil at least every 2nd
fuel fill-up and change your engine oil
more frequently. Different drivers in the
same car may experience different results.
If your oil consumption rate is greater than
expected, contact your authorized
SUBARU retailer who may perform a test
under controlled conditions.
&Checking the oil level
1. Park the vehicle on a level surface and
turn the ignition switch to the“LOCK”/
“OFF”position. If you check the oil level
just after turning the ignition switch to the
“LOCK”/“OFF”position, wait a few minutes
for the oil to drain back into the oil pan
before checking the level.
1) Oil level gauge
2) Oil filler cap
3) Oil filter
11-8

CAUTION
If the level gauge cannot be pulled
out easily, twist the level gauge right
and left, then gently pull it out.
Otherwise, you may be injured acci-
dentally straining yourself.
2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
1) Full level
2) Low level
3) Approximately 1.1 US qt (1.0 liter, 0.9
Imp qt) from low level to full level
4. Pull out the oil level gauge again.
5. Check the oil levels on both sides of
the level gauge. The engine oil level mustbe judged by the lowest of the two levels.
If the oil level is below the low level mark,
add oil so that the full level is reached.
CAUTION
.Be careful not to touch the en-
gine oil filter when removing the
oil filler cap. Doing so may result
in a burn, a pinched finger, or
may cause some other injury.
.Use only engine oil with the
recommended grade and vis-
cosity.
.Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is
correct.
NOTE
To prevent overfilling the engine oil, do
not add any additional oil above the
upper level when the engine is cold.
&Changing the oil and oil filter
Change the oil and oil filter according to
the maintenance schedule in the“War-
ranty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in
the maintenance schedule when driving
on dusty roads, when short trips are
frequently made, or when driving in
extremely cold weather.
NOTE
.Changing the engine oil and oil filter
should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil filter.
Fully trained mechanics are on standby
at a SUBARU dealer to utilize the
special tools, spare parts and recom-
mended oil for this work, and also,
used oils are properly disposed of.
.If performing oil replacement your-
self, observe the local regulations and
dispose of waste oil properly.
Maintenance and service/Engine oil

diluted with another brand or
type, the maintenance interval is
shortened to that of the mixing
coolant.
.Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
&Cooling fan, hose and con-
nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the coolant temperature high
warning light blinks or illuminates inRED,
the cooling fan circuit may be defective.
Refer to“Coolant temperature low indica-
tor light/Coolant temperature high warning
light”F3-17.
Check the fuse and replace it if necessary.
Refer to“Fuses”F11-34 and“Fuse panel
located in the engine compartment”F12-
11 .
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
If frequent addition of coolant is neces-sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness.
&Engine coolant
!Checking the coolant level
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap is
removed.
1)“FULL”level mark
2)“LOW”level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW”level mark, add coolant up to the
“FULL”level mark. If the reserve tank is
empty, remove the radiator cap and refill
coolant up to just below the filler neck as
shown in the following illustration.

Maintenance and service/Air cleaner element
1) Fill up to this level
3. After refilling the reserve tank and the
radiator, reinstall the cap and check that
the rubber gaskets inside the radiator cap
are in the proper position.
CAUTION
.Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.
.Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
!Changing the coolant
It may be difficult to change the coolant.
Have the coolant changed by your
SUBARU dealer if necessary.
The coolant should be changed according
to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
Air cleaner element
WARNING
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters
intake air but also stops flames if
the engine backfires. If the air
cleaner element is not installed
when the engine backfires, you
could be burned.
CAUTION
When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.
The air cleaner element functions as a
filter screen. When the element is perfo-
rated or removed, engine wear will be
excessive and engine life shortened.
It is not necessary to clean or wash the air
cleaner element.

Maintenance and service/Spark plugs
Spark plugs
It may be difficult to replace the spark
plugs. It is recommended that you have
the spark plugs replaced by your
SUBARU dealer.
The spark plugs should be replaced
according to the maintenance schedule
in the“Warranty and Maintenance Book-
let”.
CAUTION
Make sure the cables are replaced in
the correct order.
&Recommended spark plugs
For the recommended spark plugs, refer
to“Electrical system”F12-7.
Drive belts
It is unnecessary to check the deflection of
the drive belt periodically because your
engine is equipped with an automatic 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 the drive belt is loose, cracked or worn,
contact your SUBARU dealer.
Manual transmission oil
It is not necessary to check the transmis-
sion oil level. Check that there are no
cracks, damage or leakage. However, the
oil inspection should be performed ac-
cording to the maintenance schedule in
the“Warranty and Maintenance Booklet”.
Consult your SUBARU dealer for details.
&Recommended grade and
viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
“Manual transmission, front differential
and rear differential gear oil”F12-6.
