Engine oil Checking the oil level
Check the engine oil level at each fuel stop.
1. Park the vehicle on a level surface and stop the en-
gine.
2. Pull out the dipstick, wipe it clean, and insert it
again.
3. Be sure the dipstick is correctly inserted until it
stops with the graphic symbol “ ” on its top ap-
pearing as shown in the illustration. 1) Notch
2) Upper level
3) Lower level
4) Front of vehicle
4. Pull out the dipstick again and check the oil level on
it. If it is below the lower level, add oil to bring the level
up to the upper level.
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

result in an oil leak.
11.Close the access cover by turning it clockwise and
reinstall the six clips in their original positions.
12.Pour engine oil through the filler neck.
Oil quantity (guideline):
4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only a guideline.
The necessary quantity of oil depends on the quantity
of oil that has been drained. The quantity of drained oil
differs slightly depending on the temperature of the oil
and the time the oil is left flowing out. After pouring oil
into the engine, therefore, you must use the dipstick to
confirm that the level is correct.
13.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal.
14.Run the engine until it reaches the normal operat-
ing temperature. Then stop the engine and wait a few
minutes to allow the oil drain back. Check the oil level
again and if necessary, add more engine oil.
Recommended grade and viscosity
Oil grade:
API classification SL or SJ with the words “ENER-
GY CONSERVING” (if you cannot obtain the oil
with the SL or SJ grade, you may use SH or SG
grade oil.) or the new API certification mark (Star-
burst mark) displayed on the container.
API Service label
1) Indicates the oil quality by API designations
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving capabilities

New API Certification Mark (Starburst Mark)
In choosing an oil, you want the proper quality and vis-
cosity, as well as one that will add to fuel economy.
The following table lists the recommended viscosities
and applicable temperatures.
When adding oil, different brands may be used togeth-
er as long as they are the same API classification and
SAE viscosity as those recommended by SUBARU. SAE viscosity number and applicable temperature
*: 5W-30 is preferred.
Engine oil viscosity (thickness) affects fuel economy.
Oils of lower viscosity provide better fuel economy.
However, in hot weather, oil of higher viscosity is re-
quired to properly lubricate the engine.
Use only engine oil with the recommended
grade and viscosity.

Cooling fan, hose and connections
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 engine coolant temperature gauge exceeds the
normal operating range, the cooling fan circuit may be
defective. Check the fuse and replace it if necessary.
If the fuse is not blown, have the cooling system
checked by your SUBARU dealer.
If frequent addition of coolant is necessary, there may
be a leak in the engine cooling system. It is recom-
mended that the cooling system and connections be
checked for leaks, damage, or looseness.
Engine coolant
Checking the coolant level
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 reser-
voir 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 re-
fill as required.

a pressure gauge to adjust the tire pressures to the
values shown on the tire placard. The tire placard is lo-
cated on the door pillar on the driver’s side.
Driving even a short distance warms up the tires and
increases the tire pressures. Also, the tire pressures
are affected by the ambient temperature. It is best to
check tire pressure outdoors before driving the vehi- cle.
When a tire becomes warm, the air inside it expands,
causing the tire pressure to increase. Be careful not to
mistakenly release air from a warm tire to reduce itspressure.
NOTE The air pressure in a tire increases by approxi-
mately 4.3 psi (30 kPa, 0.3 kg/cm 2
)whenthetire
becomes warm. The tires are considered cold when the vehicle
has been parked for at least three hours or has
been driven less than one mile (1.6 km).
Do not let air out of warm tires to adjust press-
rue. Doing so will result in low tire pressure. Incorrect tire pressures detract from controllability and
ride comfort, and they cause the tires to wear abnor-mally.
Correct tire pressure (tread worn evenly)
Roadholding is good, and steering is responsive. Roll-
ing resistance is low, so fuel consumption is also low-er.

Abnormally low tire pressure (tread worn at
shoulders)
Rolling resistance is high, so fuel consumption is also
higher.
Abnormally high tire pressure (tread worn in cen-
ter)
Ride comfort is poor. Also, the tire magnifies the ef-
fects of road-surface bumps and dips, possibly result-
ing in vehicle damage.

when fully loaded and for the vehicle when towing a
trailer, adjust the tire pressures to the values that
match current loading conditions.
Driving at high speeds with excessively low tire
pressures can cause the tires to deform severe-

Windshield washer fluid
Check the level of the washer fluid at each fuel stop. If
the level is low, fill the fluid up to the neck of the reser- voir.
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. SUBARU Wind-
shield Washer Fluid contains 58.5% methyl alcohol
and 41.5% surfactant, by volume. Its freezing temper-
ature varies according to how much it is diluted, as in-
dicated below.
Never use engine coolant as washer fluid be-
cause it could cause paint damage.
