WARNING
■When using the compact spare tire
●Remember that your compact spare tire is specifically designed for
use with your vehicle. Do not use your compact spare tire on another
vehicle.
●Do not use two compact spare tires simultaneously.
●Replace the compact spare tire with a standard tire as soon as possi-
ble.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden engine braking.
●Install the compact spare tire on a front wheel.
■When storing the compact spare tire
Be careful not to catch fingers or other body parts between the compact
spare tire and the body of the vehicle.
■Speed limit when using the compact spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Failing
to observe this precaution may lead to an accident causing death or seri-
ous injury.
■When the spare tire is attached
The vehicle speed may not be correctly detected, and the following sys-
tems may not operate correctly:
●ABS & brake assist
●Vehicle stability control (VSC)
●TRAC
●Electric power steering
●Navigation system (if equipped)
●Cruise control
●LSD (if equipped)

5-2. Steps to take in an emergency
CAUTION
■Do not drive the vehicle with a flat tire.
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
■Be careful when driving over bumps with the compact spare tire
installed on the vehicle.
The vehicle becomes lower when driving with the compact spare tire
compared to when driving with standard tires. Be careful when driving
over uneven road surfaces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving
performance.
■When replacing the tires (vehicles with a tire pressure monitoring
system)
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your SUBARU dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmit-
ters (vehicles with a tire pressure monitoring system)
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your SUBARU dealer or other qualified service shop as
soon as possible. Make sure to replace the tire pressure warning valve
and transmitter when replacing the tire. (→P. 313)
■Stowing the jack
When stowing the jack in the jack holder, make sure that the part that the
jack handle attaches to is pointing towards the inside of the trunk. Failure
to do so may damage the vehicle body.

5-2. Steps to take in an emergency
If the vehicle becomes stuck
■When it is difficult to free the vehicle
Carry out the following procedures
if the tires spin or the vehicle
becomes stuck in mud, dirt, or snow:
Stop the engine. Set the parking brake and shift the select
lever to P (vehicles with an automatic transmission) or shift
lever to neutral (vehicles with a manual transmission).
Remove the mud, snow or sand from around the rear
wheels.
Place wood, stones or some other material under the rear
wheels to help provide traction.
Restart the engine.
Shift the select lever to the D or R position (vehicles with an
automatic transmission) or shift lever to 1 or R position
(vehicles with a manual transmission) and release the park-
ing brake. Then, while exercising caution, depress the
accelerator pedal.

Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the
strands which form the plies in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked
“RADIAL” is a bias-ply tire.
TUBELESS or TUBE TYPE
A tubeless tire does not have a tube and air is directly filled in the
tire. A tube type tire has a tube inside the tire and the tube main-
tains the air pressure.
Load limit at maximum cold tire inflation pressure (→P. 315)
Maximum cold tire inflation pressure ( →P. 426)
This means the pressure to which a tire may be inflated.
Summer tire or all season tire ( →P. 315)
An all season tire has “M+S” on the sidewall. A tire not marked
“M+S” is a summer tire.
“TEMPORARY USE ONLY” ( →P. 389)
A compact spare tire is identified by the phrase “TEMPORARY
USE ONLY” molded into its sidewall. This tire is designed for tem-
porary emergency use only.

Uniform Tire Quality GradingThis information has been prepared in accordance with regulations
issued by the National Highway Traffic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of
SUBARU vehicles with information on uniform tire quality grading. Your SUBARU dealer will help answer any questions you may have as
you read this information.
■DOT quality grades
All passenger vehicle tires must conform to Federal Safety
Requirements in addition to these grades. 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

Vehicle specifications
■Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use. Performance may differ significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, represent-
ing the tire’s resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a speci-
fied indoor laboratory test wheel.Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
Grade C corresponds to a level of performance which all passenger
car tires must meet under the Federal Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
