NOTICE
■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
Toyota 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
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 Toyota 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. 674)
■After taking out or stowing the spare tire
Make sure to secure the tire carrier by tightening the clamp bolt to pre-
vent the holding bracket from hitting the under body of the vehicle during
driving.
■Using the tire carrier
●As the tire carrier is designed fo r use with the compact spare tire, it
cannot be used with standard tires.
●If the spare tire is flat, do not use th e tire carrier, as the tire may not be
held securely.

NOTICE
■
To avoid damaging the tran saxle and other components
● Avoid spinning the wheels and pressing the accelerator pedal more than
necessary.
● If the vehicle remains stuck even after these procedures are performed,
the vehicle may require towing to be freed.

CAUTION
■
If the engine has to be turned off while driving
● Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Vehicles without a smart key system: Never attempt to remove the key, as
doing so will lock the steering wheel.
Vehicles with a smart key sys-
tem: Stop the engine by press-
ing and holding the “ENGINE
START STOP” switch for 3
consecutive seconds or more.
Stop the vehicle in a safe place by the road.
Press and hold for 3 seconds or more

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 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 caus e heat buildup and possible tire fail-
ure.
