11-22Maintenance and service
not be functioning normally. In this event,
go to a SUBARU dealer to have the
system inspected as soon as possible.
While the vehicle is driven, friction be-
tween tires and the road surface causes
the tires to warm up. After illumination of
the low tire pressure warning light, any
increase in the tire pressures caused by
an increase in the outside air temperature
or by an increase in the temperature in the
tires can cause the low tire pressure
warning light to turn off.
System resetting is necessary when the
wheels are changed (for example, a
switch to snow tires) and new TPMS
valves are installed on the newly fitted
wheels. Have this work performed by a
SUBARU dealer following wheel replace-ment.
It may not be possible to install TPMS
valves on certain wheels that are on the
market. Therefore, if you change the
wheels (for example, a switch to snow
tires), use wheels that have the same part
number as the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
will not fully function and the warning light
in the instrument panel will illuminate
steadily after blinking for approximately
one minute. When a tire is replaced, adjustments are
necessary to ensure continued normal
operation of the tire pressure monitoring
system. As with wheel replacement, there-
fore, you should have the work performed
by a SUBARU dealer.
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 soon as possi- ble.
If this light illuminates while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
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 air 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 possible
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.
& 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 immedi-
ately if you find any problem. NOTE . When the wheels and tires strike
curbs or are subjected to harsh treat-
ment as when the vehicle is driven on a
rough surface, they can suffer damage
WARNING
. When replacing a tire, you must
use a tire that is of the same size,
circumference, construction,
brand (tread pattern), speed sym-
bol and load index as the original
tires listed on the tire placard.
Using tires of other sizes, cir-
cumferences or constructions
may result in severe mechanical
damage to the drive train of your
vehicle and may affect ride,
handling, braking, speedometer/
odometer calibration, and clear-
ance between the body and tires.
It also may be dangerous and
lead to loss of vehicle control.
. You must install four tires that are
of the same size, circumference,
construction, manufacturer,
brand (tread pattern), degree of
wear, speed symbol and load
index. Mixing tires of different
types, sizes or degrees of wear
can result in damage to the
vehicle ’s power train. Use of
different types or sizes of tires
can also dangerously reduce
controllability and braking per-
formance and can lead to anaccident. .
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 anaccident. Aluminum wheels .
Aluminum wheels can be scratched
and damaged easily. Handle them care-
fully to maintain their appearance, perfor-
mance, 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.
–For the wheel nut tightening torque,
refer to “Tires ”F 12-8.
– For the wheel nut tightening proce-
dure, refer to “Changing a flat tire ”F 9-
6.
. Never apply oil to the threaded parts,
wheel nuts, or tapered surface of thewheel. . 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 the specific wheel. Maintenance and service

Example:
(6) Load Index: A numerical code
which specifies the maximum load
a tire can carry at the speed
indicated by its speed symbol, at
maximum inflation pressure.
For example,“104 ”means 1,984
lbs (900 kg), “100 ”means 1,764 lbs
(800 kg), “90 ”means 1,323 lbs (600
kg).
WARNING
Load indices apply only to the
tire, not to the vehicle. Putting
a load rated tire on any vehicle
does not mean the vehicle can
be loaded up to the tire ’s rated
load.
(7) Speed Rating: An alphabetical
system describing a tire ’s capability
to travel at established and prede-
termined speeds.
For example, “H ” means 130 mph (210 km/h).
WARNING
. Speed ratings apply only to
the tire, not to the vehicle.
Putting a speed rated tire on
any vehicle does not mean
the vehicle can be operated
at the tire ’s rated speed.
. The speed rating is void if
the tires are worn out, da-
maged, repaired, retreaded,
or otherwise altered from
their original condition. If
tires are repaired, re-
treaded, or otherwise al-
tered, they may not be sui-

! Tire Identification Number (TIN)
Tire Identification Number (TIN) is
marked on the intended outboard
sidewall. The TIN is composed of
four groups. Here is a brief review
of the TIN with a breakdown of its individual elements.
(1) Manufacturer
’s Identification
Mark
(2) Tire Size
(3) Tire Type Code
(4) Date of Manufacture
The first two figures identify the
week, starting with “01 ”to represent
the first full week of the calendar
year; the second two figures repre-
sent the year. For example, 0101
means the 1st week of 2001.
! Other markings
The following makings are also
placed on the sidewall. ! Maximum permissible inflation
pressure
The maximum cold inflation pres-
sure to which this tire may be
inflated. For example, “300 kPa
(44 PSI) MAX. PRESS ”.

!Maximum load rating
The load rating at the maximum
permissible weight load for this tire.
For example, “MAX. LOAD 730 kg
(1609 LBS) @ 300 kPa (44 PSI)
MAX. PRESS. ”
WARNING
Maximum load rating applies
only to the tire, not to the
vehicle. Putting a load rated
tire on any vehicle does not
mean the vehicle can be
loaded up to the tire ’s rated
load.
! Construction type
Applicable construction of this tire.
For example, “TUBELESS STEEL
BELTED RADIAL ”
! Construction
The generic name of each cord
material used in the plies (both
sidewall and tread area) of this tire.
For example, “PLIES: TREAD 2 STEEL + 2 POLYESTER + 1
NYLON SIDEWALL 2 POLYE- STER
”
! Uniform Tire Quality Grading (UTQG)
For details, refer to “Uniform tire
quality grading standards ”F 13-14 .&
Recommended tire inflationpressure
! Recommended cold tire infla-
tion pressure
For the recommended cold tire
inflation pressure for your vehicle ’s
tires, refer to “Tires ”F 12-8 .
! Vehicle placard
The vehicle placard is affixed to the driver ’s side B-pillar.
Example:
The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading infor-mation. !Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and failure of the
tire(s). Possible resulting loss of vehicle control could lead to anaccident.
! Measuring and adjusting air
pressure to achieve proper in-
flation
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month 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
specific values. 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 out-
doors 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. &
