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. 2.5-liter models

API Service label
A) Indicates the oil quality by API designations
B) Indicates the SAE oil viscosity grade
C) Indicates that the oil has fuel saving capabilities
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. ! Recommended grade and viscosity
under severe driving conditions
If the vehicle is used in desert areas, in areas with very
high temperatures, or used for heavy-duty applica-
tions such as towing a trailer, use of oil with the follow-
ing grade and viscosities is recommended.

ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
! 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
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.

it difficult to steer the vehicle in a straight line, one
of the tires and/or wheels may be damaged. Drive
slowly to the nearest authorized SUBARU dealer
and have the vehicle inspected. !
Tire pressures and wear
Maintaining the correct tire pressures helps to maxi-
mize the tires’ service lives and is essential for good
running performance. Check and, if necessary, adjust
the pressure of each tire (including the spare) at least
once a month (for example, during a fuel stop) and be-
fore any long journey.
Check the tire pressures when the tires are cold. Use 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 outside 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 kgf/cm 2
) when the tire
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 pres-sure. Doing so will result in low tire pressure.UB8201BA

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.
