New API Certification Mark (Starburst Mark)
1
Indicates the oil quality by API desig- nations
2 Indicates the SAE oil viscosity grade
3 Indicates that the oil has fuel savingcapabilities
In choosing an oil, you want the proper quality and viscosity, as well
as one that will add to fuel economy. The following table lists the rec-
ommended viscosities and applicable temperatures.
When adding oil, different brands may be used together as long as
they are the same API classification and SAE viscosity as those rec-
ommended by SUBARU.
Engine oil viscosity (thickness) affects fuel economy. Oils of lower vis-
cosity provide better fuel economy. However, in hot weather, oil of
higher viscosity is required to properly lubricate the engine.

controlled to operate when the engine coolant reaches a specific tem-
perature.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 recommended that the cooling systemand connections be checked for leaks, damage, or looseness.
Engine coolant Checking the coolant level
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, re-
move the radiator cap and refill as required.

tighten it to the specified torque.
Aluminum wheels (if equipped)
Aluminum 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
approximatly 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.
Be sure to fit tire chains on uniformly and completely around the tire,
otherwise the chains may scratch the wheel. When wheel nuts, balance weights, or the center cap is replaced, be
sure to replace them with genuine SUBARU parts designed for aluminumwheels.
Windshield washer fluid
CAUTION
Never use engine coolant as washer fluid because it could cause paint damage.
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 reservoir.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 Windshield Washer Fluid contains 58.5% methyl
alcohol and 41.5% surfactant, by volume. Its freezing temperature varies
according to how much it is diluted, as indicated below.

GAS STATION REFERENCE
Fuel:2.5 Liter models: Use only unleaded gasoline with an octane rating of 87
AKI or higher. 3.0 Liter models:
Use premium unleaded gasoline with an octane rating of
91 AKI or higher. Regular unleaded gasoline with an oc-
tane rating of 87 AKI may be used if necessary. For opti-
mum engine performance and driveability, it is recom-
mended that you use premium grade unleaded gasoline. Fuel octane rating:
This octane rating is the average of the Research Octane
and Motor Octane numbers and is commonly referred toas the Anti Knock Index (AKI). Refer to “Fuel” section in
this manual.
Fuel capacity: 16.9 US gal (64 liters, 14.1 Imp gal)
Engine oil: Use only API classification SL with the words “ENERGY
CONSERVING”
and the New API certification mark (starburst mark) dis-
played on the container.
Engine oil capacity: 2.5 liter models 4.2 US qt (4.0 liters, 3.5 Imp qt)
