properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire t hat is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc., are equipped.
• An auxiliary-supported run-flat tire is equipped.
• 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
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheels without the tire pressure warning valves and transmitters are
used.
• If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer.
● Performance may be affected in the following situations.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drivetrain as well as dan-
gerous handling characteristics, which may lead to an accident resulting in
death or serious injury.
● Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
● Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
■ When initializing the tire pressure warning system
Do not initialize the tire pressure wa rning system without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.

Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset*.
Replacement wheels are available at any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1600 km (1000 miles).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves
and transmitters (except for compact spar e tire) that allow the tire pressure
warning system to provide advance warning in the event of a loss in tire infla-
tion pressure. Whenever wheels are repl aced, tire pressure warning valves
and transmitters must be installed. ( P. 633)
WARNING
■When replacing wheels
● Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in a loss of handling control.
● Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
■ When installing the wheel nuts
● 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 an acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
● Be sure to install the wheel nuts with the
tapered ends facing inward. Installing
the nuts with the tapered ends facing
outward can cause the wheel to break
and eventually cause the wheel to come
off while driving, which could lead to an
accident resulting in death or serious
injury.

■ The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pressure changes caused by temperature.
In this case, adjusting the tire inflation pressure will turn off the warning light
(after a few minutes).
■ When a tire is replaced with a spare tire (vehicles with spare tire)
Vehicles with full-size spare tire: T he spare tire is also equipped with a tire
pressure warning valve and transmitter. The tire pressure warning light will
turn on if the tire inflation pressure of the spare tire is low. If a tire goes flat,
the tire pressure warning light will not turn off even though the flat tire has
been replaced with the spare tire. Replace the spare tire with the repaired tire
and adjust the tire inflation pressure. The tire pressure warning light will go off
after a few minutes.
Vehicles with compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and transmitter. If a tire goes flat, the tire pres-
sure warning light will not turn off even though the flat tire has been replaced
with the spare tire. Replace the spare ti re with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few
minutes.
■ Conditions that the tire pressure warning system may not function prop-
erly
 P. 637
■ If the tire pressure warning light frequently comes on after blinking for
1minute
If the tire pressure warning light frequently comes on after blinking for
1 minute when the engine switch is turned to the “ON” position (vehicles with-
out smart entry & start system) or IGNITION ON mode (vehicles with smart
entry & start system), have it checked by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
If the tire pressure warning light frequently comes on after blinking for
1 minute when you change between registered wheel sets, confirm the cor-
rect wheel set has been selected.
■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.

■ Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whose expiry date
has already passed. Otherwise, repairs conducted using the emergency tire
puncture repair kit may not be performed properly.
■ Emergency tire puncture repair kit
● The sealant has a limited lifespan. The expiry date is marked on the bottle.
The bottle of sealant should be replaced with a new bottle before the expiry
date. Contact any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer for replacement.
● 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 replaced, purchase a new bottle at any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer. The compres-
sor is reusable.
● The sealant can be used when the outside temperature is from -30°C
(-22°F) to 60°C (140°F).
● The repair kit is exclusively designed for size and type of tires originally
installed on your vehicle. Do not use it for tires that a different size than the
original ones, or for any other purposes.
● 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. Immediately 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.

WARNING
■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 repair kit in the luggage compartment.
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 doc-
tor.
● If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
