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 inspection.

Maintenance and service
– CONTINUED –
Be careful not to burn yourself because the flu-id may be hot.
"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.
" Avoid spilling fluid when adding it in the tank.

Brake fluid !Checking the fluid level
1) “MAX” level mark
2) “MIN” level mark
Check the fluid level monthly.
Check the fluid level on the outside of the reservoir. If
the level is below “MIN”, add the recommended brake
fluid to “MAX”.
Use only brake fluid from a sealed container.

"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.

Maintenance and service
"
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.
If the tire placard shows tire pressures for the vehicle
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- 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 SUB-
ARU dealer. Also have them adjusted after tire repairs
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-
