Maintenance and Service11

■When Checking or Servicing
in the Engine Compartment
While the Engine Is Running
11-3. Maintenance TipsSome clips and fender linings must be
removed before replacing the air cleaner
element or specific bulbs.■ Removing and Reinstalling
Clips▼ Removing clips
There are several types of clips used for
your vehicle.
▽Type A and D clipsType A clips Type D clips
1. Turn the clips co
unterclockwise using
a flat-head screwdriver until the center
portion of the clip is raised.
2. Remove the clips with a flat-head
screwdriver using leverage.
CAUTION
 Do not contact the belt cover
while checking the components
in the engine compartment.
Doing so may cause your hand to
slip off the belt cover and result in
an unexpected injury. Do not touch the o il filter until the
engine has cooled down
completely. Doing so may result
in a burn or other injury. Note that
the oil filter becomes very hot
when the engine is running and
remains hot for so me time after
the engine has stopped.
WARNING
A running engine can be danger-
ous. Keep your fingers, hands,
clothing, hair and tools away from
the cooling fan, belts and any other
moving engine parts. Removing
rings, watches and ties is advisable.

Engine Oil
34611-6. Engine Oil■Engine Oil ConsumptionSome 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 followi ng conditions, oil
consumption can be increased and thus
require refilling between maintenance
intervals:
 When the engine is new and within the
break-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 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 Level1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait for at least 5 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 filter2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
CAUTION
 If the level gauge is not pulled out
easily, twist the level gauge right
and left, then pull it out. Other-
wise, you may be injured acciden-
tally straining yourself. Use only engine oil with the
recommended grade and
viscosity. 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.
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.

Cooling System
348■Synthetic OilYou should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual. Refer to "Engine
Oil" P381. Also, you must follow the oil
and filter changing intervals shown in the
Warranty and Maintenance booklet.NOTESynthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.
11-7. Cooling System
■ Cooling Fan, Hose and
ConnectionsYour vehicle employs an electric cooling
fan which is thermost atically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to "Engine Coolant
Temperature Gauge"  P129.
WARNING
Never remove the radiator 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 boiling hot coolant when
the cap is removed.
CAUTION
 Vehicles are filled at the factory
with SUBARU SUPER COOLANT
that does not require the first
change for 11 years/137,500 miles
(11 years/220,000 km). This
coolant should not be mixed with
any other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. When neces-
sary to top off the coolant for any
reason, use only SUBARU
SUPER COOLANT.
If the SUBARU SUPER COOLANT
is 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.

Alloy Wheels
366NOTEWhen any of the wheels are removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driv-
ing approximately 600 miles (1,000
km). If any nut is loos e, tighten it to the
specified torque.
11-22. Alloy WheelsAlloy wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
 When any of the wheels is removed
and replaced for tire rotation or to change
a flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose,
tighten it to the specified torque.
 Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
 Never let the wheel rub against sharp
protrusions or curbs.
 When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for alloy wheels.
11-23. Windshield Washer Fluid1) “LOW” positionThe washer fluid level can be checked by
observing the position of the level on the
liquid-covered holes in the gauge. 
If the level falls below the second hole
from the bottom (the “LOW” position), add
washer fluid.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid.
WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing
during turns. The resulting loss of
vehicle control could lead to an
accident.
