When trouble arises
8-2. Steps to take in an emergency
If the vehicle becomes stuck
Stop the engine. Set the parking brake and shift the shift lever to P.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material under the tires to help
provide traction.
Restart the engine.
Shift the shift lever to the D or R and release the parking brake.
Then, while exercising caution, depress the accelerator pedal.
■ When it is difficult to free the vehicle
Carry out the following procedures if the tires spin or the vehicle

Vehicle specifications
Tire size( P. 615)
DOT and Tire Identification Number (TIN) ( P. 614)
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
Location of treadwear indicators ( P. 496)
Run-flat tire (RFT) or standard tire ( P. 570)
This vehicle can be equipped with ei ther run-flat tires (RFT) or stan-
dard tires. A “RFT” or “DSST” mark is molded on the sidewall of the
run-flat tire.
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 put into the tire.
A tube type tire has a tube inside the tire and the tube maintains the air
pressure.
Load limit at maximum cold tire inflation pressure ( P. 499)
Maximum cold tire inflation pressure ( P. 606)
This means the pressure to which a tire may be inflated.
Summer tires or all season tires ( P. 500)
An all season tire has “M+S” on the sidewall. A tire not marked “M+S”
is a summer tire.
“TEMPORARY USE ONLY” ( P. 583)
A compact spare tire is identified by the phrase “TEMPORARY USE
ONLY” molded on its sidewall. This tire is designed for temporary
emergency use only.

This information has been prepared in accordance with regulations
issued by the National Highway Tr affic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Your Toyota 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.

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 tire s depends upon the actual condi-
tions 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 conditio ns 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 hi ghest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate heat when tested under cont rolled conditions on a specified
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 le vels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can cause heat buildup and possible tire
failure.
