Correct tire pressure (tread worn evenly)
HGB033AA
Roadholding is good, and steering is responsive. Rolling resistance is
low, so fuel consumption is also lower.
Abnormally low tire pressure (tread worn at shoulders)
HSB012AA
Rolling resistance is high, so fuel consumption is also higher.

11-42
Abnormally high tire pressure (tread worn in center)
HSB013AA
Ride comfort is poor. Also, the tire magnifies the effects of road-sur-
face bumps and dips, possibly resulting 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.
WARNING
Driving at high speeds with excessively low tire pressures can
cause the tires to deform severely and to rapidly become hot. Asharp increase in temperature could cause tread separation, and
destruction of the tires. The resulting loss of vehicle controlcould 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 balanced, have
them checked and adjusted by your SUBARU 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 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
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 replaced when the tread wear indicator appears as a solid
band across the tread.
OM-H0231
WARNING
When a tire ’s tread wear indicator becomes visible, the tire is
worn beyond the acceptable limit and must be replaced immedi-
ately. With a tire in this condition, driving at high speeds in wetweather can cause the vehicle to hydroplane. The resulting lossof vehicle control can lead to an accident.
NOTE
For safety, inspect the tire tread regularly and replace the tires be- fore their tread wear indicators become visible. A) New tread

Tire rotation
OM-H0230
Tire wear varies from wheel to wheel. To maximize the life of each tire
and ensure that the tires wear uniformly, it is best to rotate the tires every
7,500 miles (12,500 km). Rotating the tires involves switching the front
and rear tires on the right-hand side of the vehicle and similarly switching
the front and rear tires on the left-hand side of the vehicle. (Each tiremust be kept on its original side of the vehicle.)
Replace any damaged or unevenly worn tire at the time of rotation. After
tire rotation, adjust the tire pressures and make sure the wheel nuts are
correctly tightened.
After driving approximately 600 miles (1,000 km), check the wheel nuts
again and retighten any nut that has become loose. Tire replacement
The wheels and tires are important and integral parts of your vehicle ’s
design; they cannot be changed arbitrarily. The tires fitted as standard
equipment are optimally matched to the characteristics of the vehicle
and were selected to give the best possible combination of running per-
formance, ride comfort, and service life. It is essential for every tire to
have a size and construction matching those shown on the tire placard
and to have a speed symbol and load index matching those shown on
the tire placard.
Using tires of a non-specified size detracts from controllability, ride com-
fort, braking performance, speedometer accuracy and odometer accu-

racy. It also creates incorrect body-to-tire clearances and inappropriately changes the vehicle ’s ground clearance.
All four tires must be the same in terms of manufacturer, brand (tread
pattern), construction, and size. You are advised to replace the tires with
new ones that are identical to those fitted as standard equipment.
For safe vehicle operation, SUBARU recommends replacing all four tires at the same time.
WARNING
All four tires must be the same in terms of manufacturer, brand
(tread pattern), construction, degree of wear, speed symbol, loadindex and size. Mixing tires of different types, sizes or degrees ofwear can result in damage to the vehicle ’s power train. Use of dif-
ferent types or sizes of tires can also dangerously reduce con-trollability and braking performance and can lead to an accident. Use only radial tires. Do not use radial tires together with
belted bias tires and/or bias-ply tires. Doing so can dangerously
reduce controllability, resulting in an accident.
Wheel replacement
When replacing wheels due, for example, to damage, make sure the re-
placement wheels match the specifications of the wheels that are fitted
as standard equipment. Replacement wheels are available from
SUBARU dealers.
WARNING
Use only those wheels that are specified for your vehicle. Wheelsnot meeting specifications could interfere with brake caliper op-eration and may cause the tires to rub against the wheel wellhousing during turns. The resulting loss of vehicle control couldlead to an accident.

Wheel covers Removing the wheel cover
HB9032BA
Insert the wheel nut wrench into the notch provided, and pry the
wheel cover off. Installing the wheel cover
HGA013BA
Align the valve with the valve hole in the cover, then fit the cover on
the wheel by tapping your hand evenly around the circumference of
the cover.
NOTE
When any of the wheels is removed and replaced for tire rotation or
to change a flat tire, always check the tightness of the wheel nuts af-
ter driving approximately 600 miles (1,000 km). If any nut is loose,

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.

Replacement of windshield wiper blades
Grease, wax, insects, or other materials on the windshield or the wiper
blade results in jerky wiper operation and streaking on the glass. If you
cannot remove the streaks after operating the windshield washer or if the
wiper operation is jerky, clean the outer surface of the windshield (or rear
window) and the wiper blades using a sponge or soft cloth with a neutral
detergent or mild-abrasive cleaner. After cleaning, rinse the windshield
and wiper blades with clean water. The windshield is clean if beads do
not form when you rinse the windshield with water.
CAUTION
Do not clean the wiper blades with gasoline or a solvent, such as
paint thinner or benzene. This will cause deterioration of thewiper blades.
If you cannot eliminate the streaking even after following this method,
replace the wiper blades using the following procedures:
