park the vehicle. y
If you feel unusual vibration while
driving or find it difficult to steer the ve-
hicle in a straight line, one of the tires
and/or wheels may be damaged. Drive
slowly to the nearest authorized SUBA-
RU dealer and have the vehicle in-
spected. „ Tire pressures and wear
Maintaining the correct tire pressures
helps to maximize the tires’ service lives
and is essential for good running perfor-
mance. 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 before 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 located
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 in-
crease. Be careful not to mistakenly re-
lease air from a warm tire to reduce its
pressure.
NOTE
y The air pressure in a tire increases
by approximately 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).
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally. y Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is re-
sponsive. Rolling resistance is low, so fuel
consumption is also lower.
800221
Do not let air out of warm tires to ad-
just pressure. Doing so will result in
low tire pressure.
B00050

11 - 3 2 Maintenance and service
yAbnormally low tire pressure (tread
worn at shoulders)
Rolling resistance is high, so fuel con-
sumption is also higher. y
Abnormally high tire pressure (tread
worn in center)
Ride comfort is poor. Also, the tire magni-
fies the effects of road-surface 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.
„ 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 caus-
es 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 sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not cor-
rectly 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* caus-
es the tires to wear on one side and re-
duces the vehicle’s running stability.
B00051B00052
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of vehi-
cle control could lead to an acci-
dent.

Maintenance and service 11 - 33
– CONTINUED –
Contact your SUBARU dealer if you no-
tice 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
1) New tread
2) Worn tread
3) Tread wear indicator
Each tire incorporates a tread wear indica-
tor, 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.
NOTE
For safety, inspect tire tread regularly
and replace the tires before their tread
wear indicators become visible. „
Tire rotation direction mark
Example of tire rotation direction mark
1) Front
If the tire has the rotation direction specifi-
cation, the tire rotation direction mark is
placed on its sidewall.
When you install a tire that has the tire ro-
tation direction mark, install the tire with
the direction mark facing forward.12 3
B00327
When a tire’s tread wear indicator
becomes visible, the tire is worn be-
yond the acceptable limit and must
be replaced immediately. With a tire
in this condition, driving at high
speeds in wet weather can cause
the vehicle to hydroplane. The re-
sulting loss of vehicle control can
lead to an accident.
ROTATION

11 - 3 4 Maintenance and service
„Tire rotation
Vehicles equipped with unidirectional tires
1) Front
Vehicles equipped with 4 non-unidirec-
tional tires
1) Front 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). Move the tires to the positions shown
in the illustration each time they are rotat-ed.
Replace any damaged or unevenly worn
tire at the time of rotation. After tire rota-
tion, adjust the tire pressures and make
sure the wheel nuts are correctly tight-
ened.
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 in-
tegral parts of your vehicle’s design; they
cannot be changed arbitrarily. The tires fit-
ted as standard equipment are optimally
matched to the characteristics of the vehi-
cle and were selected to give the best pos-
sible combination of running performance,
ride comfort, and service life. It is essential
for every tire to have a size and construc-
tion 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 comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to re-
place the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU rec-
ommends replacing all four tires at the
same time.

All four tires must be the same in
terms of manufacturer, brand
(tread pattern), construction, de-
gree of wear, speed symbol, load
index and size. Mixing tires of dif-
ferent types, sizes or degrees of
wear can result in damage to vehi-
cle’s power train. Use of different
types or sizes of tires can also
dangerously reduce controllabili-
ty and braking performance and
can lead to an accident.

Wheel replacement
When replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.
Aluminum wheels
(if equipped)
Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety. y 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 approximately 600
miles (1,000 km). If any nut is loose, tight-
en it to the specified torque. y Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel. y Never let the wheel rub against sharp
protrusions or curbs. y Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel. y When wheel nuts, balance weights, or
the center cap is replaced, be sure to re-
place them with genuine SUBARU parts
designed for aluminum wheels.
Windshield washer fluid
If you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in
the tank.
y Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires. Do-
ing so can dangerously reduce
controllability, resulting in an ac-
cident.
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could in-
terfere with brake caliper operation
and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of vehi-
cle control could lead to an acci-
dent.
Never use engine coolant as washer
fluid because it could cause paint
damage.

Washer fluid level gauge
Remove the washer tank filler cap, then
check the fluid level indicated by the level
gauge (attached to the inside of the cap).
If the level is near the “Low” mark, add flu- id until it reaches the “Hi” level on the level
gauge or the “Full” mark on the tank.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean wa- ter.
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 temper-
ature varies according to how much it is di-
luted, as indicated in the following table.
In order to prevent freezing of washer flu-
id, check the freezing temperatures in the
table above when adjusting the fluid con-
centration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the oneused previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside tem-
perature, it may freeze and block the noz-
zles.

Never use engine coolant as washer
fluid because it could cause paint
damage.
Adjust the washer fluid concentra-
tion appropriately for the outside
temperature. If the concentration is
inappropriate, sprayed washer fluid
may freeze on the windshield and
obstruct your view, and the fluid
may freeze in the reservoir tank.

Replacement of wiper blades
Grease, wax, insects, or other material on
the windshield or the wiper blade results in
jerky wiper operation and streaking on the
glass. If you cannot remove the streaks af-
ter operating the windshield washer or if
the wiper operation is jerky, clean the out-
er surface of the windshield (or rear win-
dow) 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.
If you cannot eliminate the streaking even
after following this method, replace the
wiper blades using the following proce-
dures: „Windshield wiper blades
1. Raise the wiper arm off the windshield. 1) Stopper
2. Remove the wiper blade assembly by
holding its pivot area and pushing it in the
direction shown by the arrow while de-
pressing the wiper blade stopper. 1) Metal support
3. Grasp the locked end of the blade rub-
ber assembly and pull it firmly until the
stoppers on the rubber are free of the met-
al support.
Do not clean the wiper blades with
gasoline or a solvent, such as paint
thinner or benzene. This will cause
deterioration of the wiper blades.

yBefore beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and light-
ers. Never expose a battery to an
open flame or electric sparks. Bat-
teries give off a gas which is high-
ly flammable and explosive.
yFor safety, in case an explosion
does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery.
yDo not let battery fluid contact
eyes, skin, fabrics, or paint be-
cause battery fluid is a corrosive
acid. If battery fluid gets on your
skin or in your eyes, immediately
flush the area with water thor-
oughly. Seek medical help imme-
diately if acid has entered the
eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water, and
seek medical attention immediate-
ly.
yTo lessen the risk of sparks, re-
move rings, metal watchbands,
and other metal jewelry. Never al-
low metal tools to contact the pos-
itive battery terminal and anything
connected to it WHILE you are at
the same time in contact with any
other metallic portion of the vehi-
cle because a short circuit will re-
sult.
yKeep everyone including children
away from the battery.
yCharge the battery in a well-venti-
lated area.
yBattery posts, terminals and relat-
ed accessories contain lead and
lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Batteries also contain other
chemicals known to the State of
California to cause cancer. Wash
hands after handling.
Never use more than 10 amperes
when charging the battery because
it will shorten battery life.
