●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi-

(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby
●If a radio set at a similar frequency is in use in the vehicle
●If a window tint that affects the radio wave signals is installed
●If there is a lot of snow or ice on the vehicle, particularly around the

CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If a tire is flat, repair the flat tire by using emergency tire puncture
repair kit.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pressure for those tires.)

CAUTION
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.

■Emergency tire puncture repair kit
●The sealant stored in the emergency tire puncture repair kit can be
used only once to temporarily repair a single tire. If the sealant has
been used and needs to be purchased, contact your Toyota dealer.
●The sealant can be used when the outside temperature is from -40°F
(-40°C) to 140°F (60°C).
●The repair kit is exclusively designed for size and type of tires origi-
nally installed on your vehicle. Do not use it for tires that a different
size than the original ones, or for any other purposes.
●The sealant has a limited lifespan. The expiry date is shown on the
bottle. The sealant should be replaced before the expiry date. Con-
tact your Toyota dealer.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body,
the stain may not be removable if it is not cleaned at once. Immedi-
ately wipe away the sealant with a wet cloth.
●During operation of the repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
●Do not use to check or to adjust the tire pressure.

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.
Driving with a flat tire may cause a circumferential groove on the side
wall. In such a case, the tire may explode when using a repair kit.
■Caution while driving
●Store the re pa ir kit in the luggage compartmen t.
Injuries may result in the event of an accident or sudden braking.
●The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
●Do not use repair kit for tires that are different size than the original
ones, or for any other purpose. If the tires have not been completely
repaired, it could lead to an accident causing death or serious injury.
■Precautions for use of the sealant
●Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a
doctor.
●If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
