CAUTION
■Replacing a flat tire
Observe the following precautions to
reduce the risk of death or serious
injury.
●Do not try to remove the wheel ornament by hand. Take due care in
handling the ornament to avoid unexpected personal injury.
●Never use oil or grease on the wheel bolts or wheel nuts. 
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing a
serious accident. Remove any oil or grease from the wheel bolts or
wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103
N•m, 10.5 kgf•m) as soon as possible after changing wheels. 
Failure to follow these precautions could cause the nuts to loosen and
the wheels may fall off, which could lead to an accident causing death
or serious injury.
●Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the ve hicle is moving.
■When using the compact spare tire
●Remember that your spare tire is specifically designed for use with
your vehicle. Do not use your spare tire on another vehicle.
●Do not use two spare tires simultaneously.
●Replace the compact spare tire with a standard tire as soon as possi-
ble.
●Avoid sudden acceleration, deceleration and braking, as well as sharp
cornering.
■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.

NOTICE
■Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.

Driving even a short distance with a fl at 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 drivin g 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
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your To yota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.

If the vehicle becomes stuck
CAUTION
■When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the sur-
rounding area is clear, to avoid striking other vehicles, objects or persons.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
■ When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed. 
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt, or snow.
Stop the hybrid system. Set t he parking brake and push the
“P” position switch.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material to help provide
traction under the tires.
Restart the hybrid system.
Shift the shift lever to “D” or “R” and carefully apply the
accelerator to free the vehicle.STEP1

Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the
strands which form the plies in a tire.
Summer tire or all season tire
( P. 446)
An all season tire has “M+S” on the sidewall. A tire not marked
“M+S” is a summer 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. 579)
Maximum cold tire in flation pressure ( P. 579)
This means the pressure to which a tire may be inflated.
Uniform Tire Quality Grading
For details, see “Uniform Tire Quality Grading” that follows.
“TEMPORARY USE ONLY” ( P. 525)
A compact spare tire is identified by the phrase “TEMPORARY USE
ONLY” molded into its sidewall. This tire is designed for temporary
emergency use only.

Uniform Tire Quality Grading
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 answ er 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
■ 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 de pends upon the actual conditions
of their use, however, and may depart 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 ab ility 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.
The grade C corresponds to a level of performance which all passen-
ger car tires must meet under the Federal Motor Vehicle Safety Stan-
dard No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a
tire that 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 fail-
ure.
