5-2. Steps to take in an emergency
Stow the flat tire, tire jack and all tools.
■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY US
E
ONLY” on the tire sidewall.
Use the compact spare tire tem porarily only in an emergency.
●Make sure to check the tire pressure of the compact spare tire.
(  P. 468)
■When using the compact spare tire
As the compact spare tire is not equipped with the tire pressure warning
valve and transmitter, low infla tion pressure of the spare tire will not be
warned. Also, if you replace the compact spare tire after the t ire pressure
warning light comes on, the light remains on.
■If you have a flat rear tire
Install the compact spare tire on the front of the vehicle. Per form the fol-
lowing steps.
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of
the vehicle.
■After completing the tire change
The tire pressure warning system must be reset. (P. 3 4 6 )

WARNING
■Using the tire jack
Improper use of the tire jack may lead to death or serious inju
ries due to
the vehicle suddenly falling off the jack.
●Do not use the tire jack for any purpose other than replacing t ires or
installing and removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat
tire.
Do not use it on other vehicles, and do not use other tire jack s for
replacing tires on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not put any part of your body under the vehicle supported by a jack.
●Do not start or run the engine while your vehicle is supported by the
jack.
●Do not raise the vehicle while someone is in it.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a height greater than that required to
replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that n o one
working on or near the vehicle may be injured.

WARNING
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehicl e has been driven.
After the vehicle has been driven the disc wheels and the area around
the brakes will be extremely hot . Touching these areas with han ds, feet
or other body parts w hile changing a tire, e tc. may result in burns.
●Do not attach a heavily damaged wheel ornament, as it may fly o ff the
wheel while the ve hicle is moving.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 89 ft•lb f (120
N•m, 12.2 kgf•m) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been spe cifi-
cally designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nu t
threads or bolt holes of the wheel, have the vehicle inspected by
your Toyota dealer.
• When installing the wheel nuts, be sure to install them with t he
tapered ends facing inward. ( P. 358)

NOTICE
■Do not drive the vehicle with a flat tire.
Do not continue drivi ng with a flat tire.
Driving even a short distance wi th 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 d riving with the compact spare tire
compared to when driving with standard tires. Be careful when d riving
over uneven road surfaces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to t he compact spare tire.
Tire chains may damage the vehicle body and adversely affect dr iving
performance.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact yo ur Toyota dealer as the tire pressure
warning valve and transmitter ma y be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmi t-
ters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning val ve and
transmitter when replacing the tire. ( P. 3 4 6 )
■Stowing the jack
When stowing the jack in the jack holder, make sure that the pa rt that the
jack handle attaches to is pointing towards the inside of the t runk. Failure
to do so may damage the vehicle body.

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. 3 4 8 )
Maximum cold tire inflation pressure ( P. 4 6 8 )
This means the pres sure to which a tire may be inflated.
Summer tire or all season tire ( P. 3 4 8 )
An all season tire has “M+S” on t he sidewall. A tire not marked
“M+S” is a summer tire.
“TEMPORARY USE ONLY” ( P. 4 2 9 )
A compact spare tire is identified by the phrase “TEMPORARY
USE ONLY” molded into its sidewa ll. This tire is designed for tem-
porary emergency use only.

480 6-1. Specifications
Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either s epa-
rately or in combination, can cause heat buildup and possible t ire fail-
ure.
