Types of Tires
You should be familiar with type of tires
present on your vehicle.
▼
Summer tires
The factory-installed tires on your new
vehicle are summer tires.
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires.
▼A ll season tires
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads. All season tires are identified by “ALL
SEASON” and/or “M+S” (Mud & Snow) on
the tire sidewall.
▼
Wi
nter (snow) tires
Winter tires are best suited for driving on
sn ow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
NOTEIf the tread wears down below 0.16 in.
(4mm) on snow tires the effectiveness
of snow tires is lost.
▼
Lo w profile tires
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to
use snow tires or tire chains on snowy
and/or icy roads and drive carefully at a
speed appropriate for road and weather
conditions.
NOTELow profile tires may cause greater
damage than usual to the wheel when
receiving impact from the road sur-
face. Therefore pay attention to the fol-
lowing: 
Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
 Avoid pot holes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■
Tire Pressure Monitoring
Syste m (TPMS) (If Equipped)
The tire pressure monitoring system
provides the driver with a warning
message by sending a signal from a
sensor that is installed in each wheel
when tire pressure is severely low. The
tire pressure monitoring system will acti-
vate only when the vehicle is driven. Also,
this system may not react immediately to
a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to pres-
sures higher than those shown on the tire
inflation pressure label. Specifically,
inflate them by an extra 1 psi (6.9 kPa,
0.07 kgf/cm
2) for every difference of 10°F

Tire Inspection
Check on a daily basis that the tires
are free from serious damage, nails,
and stones. At the same time, check
the tires for abnormal wear.
Contact your SUBARU dealer
immediately if you find any problem.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
inspected.
 Tires should be replaced if:
– You have tire damage such
as cuts, splits, cracks deep
enough to expose the fabric or
bulges indicating internal
damage
WARNING
If the low tire pressure warning light
does not illuminate briefly after the
ignition switch is turned ON or the
light illuminates steadily after blink-
ing for approximately one minute,
you should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as so on as possi-
ble.If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Oth-
erwise an accident involving
serious vehicle damage and serious
personal injury could occur.1) Keep driving straight ahead while gradually reducing speed.2) Slowly pull off the road to a safeplace.If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose ai r rapidly. If you
have a flat tire, replace it with a
spare tire as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possi-
ble for tire and sensor replacement
and/or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.

Maintenance and Service11
– CONTINUED –
– A tire goes flat repeatedly or
cannot be properly repaired
due to the size or location of a
cut or other damage
If you are not su re, consult with
your SUBARU dealer.
 Any tires over 6 years old must
be checked by a qualified techni-
cian even if they have seldom or
never been used or damage is
not obvious.
■
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
center 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 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 3 hours or has
been driven less than 1 mile (1.6
km).
Incorrect tire pressures detract from
controllability and ride comfort, and
they cause the tires to wear abnor-
mally.
 Correctly inflated tires (tread
worn evenly)
B02109
WARNING
Do not let air out of warm tires
to adjust pressure. Doing so
will result in low tire pressure.

Tires and Wheels
362Roadholding is good, and steering
is responsive. Rolling resistance is
low, so fuel consumption is also
lower.
Under inflated tires (tread worn at
shoulders) Rolling resistance is high, so fuel
consumption is also higher.

Over inflated tires (tread worn in
center) Ride comfort is poor. Also, the tire
magnifies the effects of road
surface bumps and dips, possibly
resulting in vehicle damage.

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 destruc-
tion of the tires. The resulting
loss of vehicle control could
lead to an accident.

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 opti-
mally 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),
construction, 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.
■
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

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 wearFor 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
driver’s center pillar.
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.- Ride- Handling- Braking- Speedometer/Odometer cali- bration- Clearance between the bodyand the 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 reduce
controllability, resulting in an
accident.

Alloy Wheels
366NOTEWhen 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 driv-
ing approximately 600 miles (1,000
km). If any nut is loose, tighten it to the
specified torque.
11-22. Alloy WheelsAlloy 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 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.
11-23. Windshield WasherFluid1) “LOW” positionThe washer fluid level can be checked by
observing the position of the level on the
liquid-covered holes in the gauge.
If the level falls below the second hole
from the bottom (the “LOW” position), add
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.
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
during turns. The resulting loss of
vehicle control could lead to an
accident.
