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 pos-
sible leakage. Consult your SUBARU dealer for in- spection.
WARNING
Be careful not to burn yourself because the fluid may be hot.
CAUTION

When power steering fluid is being added,
use only clean fluid, and be careful not to al- low any dirt into the tank. And never use dif-
ferent brands together. Avoid spilling fluid when adding it in the
tank.
Recommended fluid
“ Dexron III ” Type Automatic Transmission Fluid

NOTE The air pressure in a tire increases by approxi-
mately 4.3 psi (30 kPa, 0.3 kg/cm 2
) when the tire
becomes warm. The tires are considered cold when the vehicle
has been parked for at least three hours or hasbeen driven less than one mile (1.6 km).
WARNING
Do not let air out of warm tires to adjust
pressrue. Doing so will result in low tire pres- sure.
Incorrect tire pressures detract from controllability
and ride comfort, and they cause the tires to wear
abnormally.
Correct tire pressure (tread worn evenly)
Roadholding is good, and steering is responsive.
Rolling resistance is low, so fuel consumption is
also lower.

WARNING
Driving at high speeds with excessively low tire pressures can cause the tires to deform
severely 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 toan accident.
Wheel balance
Each wheel was correctly balanced when your ve-
hicle was new, but the wheels will become unbal-
anced as the tires become worn during use. Wheel
imbalance causes the steering wheel to vibrate
slightly at certain vehicle speeds and detracts fromthe vehicle ’s straight-line stability. It can also cause
steering and suspension system problems and ab-
normal tire wear. If you suspect that the wheels are
not correctly balanced, have them checked and ad-
justed by your SUBARU dealer. Also have them ad-
justed after tire repairs and after tire rotation. NOTE Loss of correct wheel alignment* causes the tires to wear on one side and reduces the ve-
hicle’ s running 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
performance.
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
