■ Warning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.
■ Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power steering system warning light may come on
and the warning buzzer may sounds.
■ When the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 407, 422
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
● Check the tire inflation pressure and adjust to the appropriate level.
● If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
■ The tire pressure warning light may come on due to natural causes
(vehicles with a tire pressure warning system)
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 a tire pressure
warning system)
The spare tire is not equipped with a tire pressure warning valve and trans-
mitter. 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 pres-
sure warning light will go off after a few minutes.

■ If the tire pressure warning system is not functioning (vehicles with a
tire pressure warning system)
The tire pressure warning system will be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.)
● If tires not equipped with 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
● If the tire inflation pressure is 500 kPa (5.1 kgf/cm2 or bar, 73 psi) or higher
The tire pressure warning system may be disabled in the following conditions:
(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 wheels
or wheel housings
● If non-genuine Toyota wheels are used (Even if you use Toyota wheels, the
tire pressure warning system may not work properly with some types of
tires.)
● If tire chains are used
■ If the tire pressure warning light frequently comes on after blinking for 1
minute (vehicles with a tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1
minute when the power switch is turned on, have it checked by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.

WARNING
■When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
■ If the tire pressure warning light comes on (vehicles with a tire pres-
sure warning system)
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 infla-
tion pressure immediately.
● If the tire pressure warning light comes on even after tire inflation pressure
adjustment, it is probable that you have a flat tire. Check the tires. If a tire
is flat, change it with the spare tire and have the flat tire repaired by the
nearest authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
● 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 (vehicles with a tire
pressure warning system)
The tire pressure warning system may not activate immediately.
NOTICE
■ To ensure the tire pressure warning system operates properly (vehi-
cles with a tire pressure warning system)
Do not install tires with different specifications or makers, as the tire pres-
sure warning system may not operate properly.

Vehicles with aluminum wheels
Remove the center wheel orna-
ment by pushing from the
reverse side.
Be careful not to lose the wheel
ornament.
Stow the flat tire, tire jack and all tools.
■ The compact spare tire
● The compact spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
● Make sure to check the tire inflation pressure of the compact spare tire.
( P. 463)
■ After completing the tire change (vehicles with a tire pressure warning
system)
The tire pressure warning system must be reset. ( P. 342)
■ When using the spare tire (include compact spare tire) (vehicles with a
tire pressure warning system)
As the spare tire is not equipped with a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare tire will not be indicated by the tire
pressure warning system. Also, if you r eplace a flat tire with the spare tire
after the tire pressure warning light comes on, the light remains on.
■ If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle. Per-
form the following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehi-
cle.
Fit tire chains to the front tires.

Inflate the tire until the specified
air pressure is reached.
The sealant will be injected
and the pressure will surge
and then gradually decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 minute
(5 minutes at low tempera-
ture) after the switch is
turned on.
Inflate the tire until the speci-
fied air pressure.
• If the tire inflation pressure is
still lower than the specified
point after inflation for 35 min-
utes with the switch on, the tire
is too damaged to be repaired.
Turn the compressor switch off
and contact any authorized
Toyota dealer or repairer, or
another duly qualified and
equipped professional.
• If the tire inflation pressure exceeds the specified air pressure, let out
some air to adjust the tire inflation pressure. ( P. 433,463)

■If the tire is inflated to more than the specified air pressure
Check that the air pressure indicator shows the specified air pressure.
If the air pressure is under the designated pressure, turn the compressor
switch on again and repeat the inflation procedure until the specified air
pressure is reached.
■ The tire pressure warning valve and transmitter
● After a tire is repaired with the emergency tire puncture repair kit should be
replaced.
● Even if the tire inflation pressure is at the recommended level, the tire pres-
sure warning light may come on/flash.
■ 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 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
dealer or repairer, or another duly qualified and equipped professional. The
compressor 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.
