NOTE

.

When the wheels and tires

strike curbs or are subjected to
harsh treatment as when the
vehicle is driven on a rough
surface, they can suffer damage
that cannot be seen with the
naked eye. This type of damage
does not become evident until
time has passed. Try not to drive
over curbs, potholes or on other
rough surfaces. If doing so is
unavoidable, keep the vehicle’s
speed down to a walking pace or
less, and approach the curbs as
squarely as possible. Also, make
sure the tires are not pressed
against the curb when you park
the vehicle.

.

If you feel unusual vibration

while driving or find it difficult to
steer the vehicle in a straight line,
one of the tires and/or wheels
may be damaged. Drive slowly to
the nearest authorized SUBARU
dealer and have the vehicle in-
spected.

&

Tire pressures and wear

Maintaining the correct tire pres-
sures helps to maximize the tires’
service lives and is essential for
good running performance. Check
and, if necessary, adjust the pres-
sure of each tire and the spare (if
equipped) at least once a month
and before any long journey.

Tire inflation pressure label

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
inflation pressure label. The tire
inflation pressure label 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 out-
side temperature. It is best to check
tire pressure outdoors before driv-
ing the vehicle.

When a tire becomes warm, the air
inside it expands, causing the tire
pressure to increase. Be careful not
to mistakenly release air from a
warm tire to reduce its pressure.

NOTE

.

The air pressure in a tire

increases by approximately 4.3
psi (30 kPa, 0.3 kgf/cm

2

) when the

tire becomes warm.

.

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).

WARNING

Do not let air out of warm tires
to adjust pressure. 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.

1) Correct tire pressure (tread

worn evenly)
Roadholding is good, and
steering is responsive. Rolling
resistance is low, so fuel con-
sumption is also lower.

2) Under inflated tire (tread worn

on shoulders)
Rolling resistance is high, so
fuel consumption is also high-
er.

3) Over inflated tire (tread worn in

the center)
Ride comfort is poor. Also, the
tire magnifies the effects of
road-surface bumps and dips,
possibly resulting in vehicle
damage.

If the tire inflation pressure label
shows tire pressures for the vehicle
when fully loaded, adjust the tire
pressures to the values that match
the loading conditions.

WARNING

Driving at high speeds with
excessively low tire pressures
can cause the tires to deform
severely and to rapidly heat
up. A sharp increase in tem-
perature could cause tread
separation, and destruction of
the tires. The resulting loss of

Maintenance and service/Tires and wheels

(419,1)

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 steer-
ing wheel to vibrate slightly at
certain vehicle speeds and detracts
from the vehicle’s straight-line sta-
bility. 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.

CAUTION

Loss of correct wheel align-
ment 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.

NOTE
The suspension system is de-
signed 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

1) New tread
2) Worn tread
3) 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 replaced when the
tread wear indicator appears as a
solid band across the tread.

(420,1)

WARNING

When a tire’s tread wear indi-
cator becomes visible, the tire
is worn beyond 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 hydro-
plane. The resulting loss of
vehicle control can lead to an
accident.

NOTE
For safety, inspect tire tread
regularly and replace the tires
before their tread wear indicators
become visible.

&

Rotational direction of tires

Example of rotational direction
marked on the sidewall

1) Front

If the tire have the specific rotational
direction, refer to the arrow marked
on the sidewall.

The arrow should be pointing for-
ward when the wheels are fitted.

Tire wear varies from wheel to
wheel. Move the tires to the posi-
tions shown in the illustration each
time they are rotated. For the tire
rotation schedule, refer to the “War-
ranty and Maintenance Booklet”.

Replace any damaged or unevenly
worn tires at the time of rotation.
After tire rotation, adjust the tires
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.

For handling alloy wheels (if equipped),
refer to “Alloy wheels”

&

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 perfor-
mance, ride comfort, and service life. It is
essential for every tire to have a size and
construction matching those shown on the
tire inflation pressure label and to have a
speed symbol and load index matching
those shown on the tire inflation pressure
label.

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
replace the tires with new ones that are
identical to those fitted as standard equip-
ment.

For safe vehicle operation, SUBARU
recommends replacing all four tires at the
same time.

WARNING

.

When replacing or installing

tire(s), all four tires must be the
same for the following items.

(a) Size

(b) Speed symbol

(c) Load index

(d) Circumference

(e) Construction

(f) Manufacturer

(g) Brand (tread pattern)

(h) Degrees of wear

For items (a) to (c), you must
obey the specification that is
printed on the tire inflation pres-
sure label. The tire inflation pres-
sure label is located on the dri-
ver’s door pillar.

If all the four tires are not the
same for items (a) to (h), serious
mechanical damage could be
caused to the drivetrain of the
car, and affect the followings.

and tires

It also may be dangerous and
lead to loss of vehicle control,
and it 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 re-
duce controllability, resulting in
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.

WARNING

Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of
vehicle control could lead to an
accident.

NOTE

When any of the wheels are removed
and replaced for tire rotation or for any
other reason, always check the tight-
ness of the wheel nuts after driving
approximately 600 miles (1,000 km). If
any nut is loose, tighten it to the
specified torque.

&

Wheel covers (if equipped)

!

Removing the wheel cover

If your vehicle has wheel covers, remove
them by holding and pulling the areas
indicated in the illustration.

CAUTION

Use gloves to protect your hands
when removing wheel covers.

Installing the wheel cover

1)

Valve hole

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.

Alloy wheels (if equipped)

Alloy wheels can be scratched and da-
maged easily. Handle them carefully to
maintain their appearance, performance,
and safety.

.

When any of the wheels are removed

and replaced for tire rotation or to change a
flat tire, always check the tightness of the
wheel nuts after driving approximately 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.

.

When wheel nuts, balance weights, or

the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for alloy wheels.

.

When stacking and storing removed

tires, place shock-absorbing material be-
tween the tires to protect the wheels from
becoming scratched.

&

Adding the windshield
washer fluid

CAUTION

Never use engine coolant as washer
fluid because it could cause paint
damage.

Remove the washer tank filler cap, then
add windshield washer fluid.

&

Windshield washer fluid

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.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used 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
temperature, it may freeze and block the
nozzles.

CAUTION

.

Adjust the washer fluid concen-

tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.

freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle’s paint, wiper blades
or washer system.

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
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 benzine. This
will cause deterioration of the
wiper blades.

.

While removing the wiper blades

from the wiper arms, do not
return the wiper arms to the
original positions. Otherwise,
the windshield surface may be
scratched.

.

When returning the raised wiper

arms to the original positions,

carefully return the wiper arms on
the windshield by hand. You
should not return the wiper arms
to the windshield only by the
return spring. Otherwise, the wi-
per arms may be deformed and/or
the windshield surface may be
scratched.

.

When you are going to raise the

passenger-side wiper arm, first
raise the driver-side wiper arm.
Otherwise, the passenger-side
wiper assembly and driver-side
wiper assembly will touch each
other, possibly resulting in
scratches.

.

Return the passenger-side wiper

arm to its original position before
returning the driver-side wiper
arm to its original position. Other-
wise, the passenger-side wiper
assembly and driver-side wiper
assembly will touch each other,
possibly resulting in scratches.

If you cannot eliminate the streaking even
after following this method, replace the
wiper blades using the following proce-
dures.

any battery, be sure to extinguish
all cigarettes, matches, and light-
ers. Never expose a battery to an
open flame or electric sparks.
Batteries give off a gas which is
highly flammable and explosive.

.

For safety, in case an explosion

does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery.

.

Do 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 im-
mediately.

.

To lessen the risk of sparks,

remove rings, metal watchbands,
and other metal jewelry. Never
allow metal tools to contact the
positive battery terminal and any-
thing connected to it WHILE you
are at the same time in contact
with any other metallic portion of
the vehicle because a short cir-
cuit will result.
