8-2. Steps to take in an emergency
■ 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. 415, 430
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.

jack, leading to death or serious injury.
●Do not use the tire jack for any purpose other than replacing tires or install-
ing and removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat tire.

ing tires on this vehicle.
●Put the jack properly in its jack point.
●Do not put any part of your body under the vehicle while it is supported by
the jack.
●Do not start the hybrid system or drive the vehicle while the vehicle is sup-

WARNING
■ Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care in
handling the ornament to avoid unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes immediately
after the vehicle 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 hands, feet
or other body parts while changing a tire, etc. may result in burns.
●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 103 N·m
(10.5 kgf·m, 76 ft·lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or
bolt holes of the wheel, have the vehicle inspected by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
• When installing the wheel nuts, be sure to install them with the tapered
ends facing inward. (P. 365)

Installing the spare tire
Remove any dirt or foreign mat-
1
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come
off.
2
Install the tire and loosely tighten each wheel nut by hand by
approximately the same amount.
When replacing a steel wheel
Tapered portion
with a steel wheel (including a
compact spare tire), tighten the
wheel nuts until the tapered
portion comes into loose con-
tact with the disc wheel seat.
