Drive belts
1) Power steering pump pulley
2) Air conditioner compressor pulley
3) Crank pulley
The alternator, power steering pump, and air condi-
tioner compressor depend on drive belts. Satisfactory
performance requires that belt tension be correct.
To check belt tension, place a straightedge (ruler)
across two adjacent pulleys and apply a force of 22 lbs
(98 N, 10 kg) midway between the pulleys by using a
spring scale. Belt deflection should be the amount
specified. If a belt is loose, cracked, or worn, contact your SUBARU dealer.

Power steering fluid „
Checking the fluid level
1) Reservoir tank
The power steering fluid expands greatly as its tem-
perature rises; the fluid level differs according to fluid
temperature. Therefore, the reservoir tank has two dif-
ferent checking ranges for hot and cold fluids.
Check the power steering fluid level monthly.
1. Park the vehicle on a level surface, and stop the en-
gine.

1) Specified range
2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has been run:
Check that the oil level is between “HOT MIN” and
“HOT MAX” on the surface of the reservoir tank.
When the fluid is cool before the vehicle is run: Check
that the oil level is between “COLD MIN” and “COLD
MAX” on the surface of the reservoir tank.
3. If the fluid level is lower than the applicable “MIN”
line, add the recommended fluid as necessary to bring
the level between the “MIN” and “MAX” line.
If the fluid level is extreme low, it may indicate possible
leakage. Consult your SUBARU dealer for an inspec- tion.
Be careful not to burn yourself because the flu-id may be hot.
y
When power steering fluid is being added,
use only clean fluid, and be careful not to allow
any dirt into the tank. And never use different
brands together.
y Avoid spilling fluid when adding it in the tank.

NOTE yThe air pressure in a tire increases by approxi-
mately 4.3 psi (30 kPa, 0.3 kgf/cm 2
) when the tire
becomes warm. y 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.
Incorrect tire pressures detract from controllability and
ride comfort, and they cause the tires to wear abnor-
mally. y
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.

ly and to rapidly become hot. A sharp increase
in temperature could cause tread separation,
and destruction of the tires. The resulting loss
of vehicle control could lead to an accident.
„ Wheel balance
Each wheel was correctly balanced when your vehicle
was new, but the wheels will become unbalanced as
the tires become worn during use. Wheel imbalance
causes the steering wheel to vibrate slightly at certain
vehicle speeds and detracts from the vehicle’s
straight-line stability. It can also cause steering and
suspension system problems and abnormal tire wear.
If you suspect that the wheels are not correctly bal-
anced, have them checked and adjusted by your
SUBARU dealer. Also have them adjusted after tire re-
pairs and after tire rotation.
NOTE
Loss of correct wheel alignment* causes the tires
to wear on one side and reduces the vehicle’s run-
ning stability. Contact your SUBARU dealer if you
notice abnormal tire wear.
*: The suspension system is designed to hold each wheel at
a certain alignment (relative to the other wheels and to the
road) for optimum straight-line stability and cornering perfor- mance. „
Wear indicators
A) New tread
B) Worn tread
1) Tread wear indicator
Each tire incorporates a tread wear indicator, which
becomes visible when the depth of the tread grooves
decreases to 0.063 in (1.6 mm). A tire must be re-
placed when the tread wear indicator appears as a
solid band across the tread.
