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.

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.

compiled according to Code of Federal
Regulations “Title 49, Part 575”.
13-2. Tire Information■Tire LabelingMany markings (e.g . Tire size, Tire
Identification Number or TIN) are
placed on the sidewall of a tire by
tire manufacturers. These marking
can provide you with useful informa-
tion on the tire.
▼ Tire size
Your vehicle comes equipped with
P-Metric tire size. It is important to
understand the sizing system in
selecting the proper tire for your
vehicles. Here is a brief review of
the tire sizing system with a break-
down of its individual elements.
▽ P Metric
With the P-Metric system, Section
Width is measured in millimeters.
To convert millimeters into inches,
divide by 25.4. The Aspect Ratio
(Section Height divided by Section
Width) helps provide more dimen-
sional information about the tire
size. Example:
(1) P = Certain tire type used on
light duty vehicles such as
passenger cars
(2) Section Width in millimeters
(3) Aspect Ratio (= section height ÷
section width).
(4) R = Radial Construction
(5) Rim diameter in inches
▽
Load and Speed Rating Descrip-
tions
The load and speed rating descrip-
tions will appear following the size
designation.
They provide two important facts
about the tire. First, the number
designation is its load index.
Second, the letter designation indi-
cates the tire’s speed rating.Example:
P 205 / 60 R 16(1)

(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, “
91” means 1,356 lbs
(615 kg), “90” means 1,323 lbs (600 kg),
“89
” means 1,279 lbs (580 kg)
(7) Speed Rating: An alphabetical
system describing a tire’s capability
to travel at established and prede-
termined speeds.
For example, “
V” means 149 mph
(240 km/h) ▼
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 indi-
vidual elements. (1) DOT symbol*
(2) Manufacturer’s Identification
Mark
(3) Tire Size Code
(4) Tire Type Code
(5) 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.
*: The DOT symbol certifies that the tire conforms to applicable
Federal Motor Vehicle Safety
Standards.
▼ Other markings
The following makings are also
placed on the sidewall.
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.
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,
damaged, repaired,
retreaded, or otherwise
altered from their original
condition. If tires are
repaired, retreaded, or other-
wise altered, they may not be
suitable for original equip-
ment tire designed loads and
speeds.

equal to or greater than 110,
compared to the ASTM E1136-93
Standard Reference Test Tire,
when using the snow traction test as described in ASTM F-1805-00,
Standard Test Method for Single
Wheel Driving Traction in a Straight
Line on Snow-and Ice-Covered
Surfaces, and that is marked with
an Alpine Symbol “ ” on at least
one sidewall.

Test rim

testing, and it may be any rim listed
as appropriate for use with that tire.
 Tread
That portion of a tire that comes into
contact with the road.
 Tread rib
A tread section running
circumferentially around a tire.
 Tread separation
Pulling away of th e tread from the
tire carcass.
 Treadwear indicators (TWI)
The projections within the principal
grooves designed to give a visual
indication of the degrees of wear of
the tread. 
Vehicle capacity weight

406Suspension, bearings, axles and
other parts of the body could break
or experience accelerated wear that
will shorten vehicle life.
 Tires could fail.
 Tread separation could occur.
 Tire could separate from its rim.■ Steps for Determining
Correct Load Limit1. Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg
or XXX lbs.” on your vehicle’s
placard.
2. Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.
3. Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “
XXX
” amount equals
1,400 lbs (635 kg) and there will be
five 150 lbs (68 kg) passengers in your vehicle, the amount of avail-
able cargo and luggage load
capacity is 650 lbs (1,400
− 750 (5 ×
150) = 650 lbs).
5. Determine the combined weight
of luggage and cargo being loaded
on the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your
vehicle.
13-3. Uniform Tire Quality Grading StandardsThis information i ndicates the rela-
tive performance of passenger car
tires in the area of treadwear, trac-
tion, and temperature resistance.
This is to aid the consumer in
making an informed choice in the
purchase of tires.
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
TREADWEAR 200 TRACTION AA
TEMPERATURE A
The quality grades apply to new
pneumatic tires for use on
passenger cars. However, they do
not apply to deep tread, winter type
snow tires, space-saver or tempo-
rary use spare tires, tires with
nominal rim diameters of 12 inches
or less, or to some limited produc-
tion tires.
