Electric power steering system
warning light (warning buzzer)

When the 12-volt battery charge
becomes insufficient or the voltage
temporarily drops, the electric power
steering system warning light may

come on and the warning buzzer
may sound.

At this time, the functions of the air
conditioning, etc. may be partially
limited in order to reduce the power
consumption of the 12-volt battery.

■

When the tire pressure warning
light comes on

Inspect the tires to check if a tire is
punctured.

If a tire is punctured:



P.496, 484

If none of the tires are punctured:

Turn the power switch off then turn it
to ON.

Check if the tire pressure warning
light comes on or blinks.



If the tire pressure warning light
blinks for approximately 1 minute
then stays on

There may be a malfunction in the
tire pressure warning system. Have
the vehicle inspected by your
Toyota dealer immediately.



If the tire pressure warning light
comes on

After the temperature of the tires
has lowered sufficiently, check the
inflation pressure of each tire and
adjust them to the specified level.

If the warning light does not turn off
even after several minutes have
elapsed, check that the inflation
pressure of each tire is at the speci-
fied level and perform the tire infla-
tion pressure setting procedure.

If the warning light does not turn off

even after several minutes have

elapsed since performing the tire

inflation pressure setting proce-

dure, have the vehicle inspected by

your Toyota dealer as soon as pos-

sible.

■

The tire pressure warning light

The tire pressure warning light may

come on due to natural causes such

as natural air leaks and tire inflation

pressure changes caused by tem-

perature. 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

compact spare tire (vehicles

with compact spare tire)

The compact spare tire is not

equipped with a tire pressure warn-

ing valve and transmitter. 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 standard tire and adjust the

tire inflation pressure. The tire pres-

WARNING

■

If a warning light comes on or

a warning buzzer sounds

when a warning message is

shown on the multi-informa-

tion display

Check and follow the message

shown on the multi-information

display.
Failure to do so may result in

death or serious injury.

: Warning lights illuminate in red

or yellow and the warning

buzzer beeps once or sounds

continuously.

■

When the electric power

steering system warning light

comes on

When the light comes on yellow,

the assist to the power steering is

restricted. When the light comes

on red, the assist to the power

steering is lost and handling oper-

ations of the steering wheel

become extremely heavy.

If the steering wheel becomes

heavier than usual when operat-

ing, hold firmly and operate using

more force than usual.

■

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 con-

trol and result in death or serious

injury.

●

Stop your vehicle in a safe

place as soon as possible.

Adjust the tire inflation pressure

immediately.

474

7-2. Steps to take in an emergency

WARNING

●

If the tire pressure warning light

comes on even after tire infla-

tion 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 Toyota dealer.

●

Avoid abrupt maneuvering and

braking. If the vehicle tires dete-

riorate, 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 recom-

mended by the vehicle manufac-

turer on the vehicle placard or tire

inflation pressure label (tire and

load information label). (If your

vehicle has tires of a different size

than the size indicated on the

vehicle placard or tire inflation

pressure label [tire and load infor-

mation label], you should deter-

mine the proper tire inflation

pressure for those tires.)

As an added safety feature, your

vehicle has been equipped with a

tire pressure monitoring system

(TPMS-tire pressure warning sys-

tem) that illuminates a low tire

pressure telltale (tire pressure

warning light) when one or more

of your tires is significantly under-

inflated. Accordingly, when the

low tire pressure telltale (tire pres-

sure warning light) illuminates,

you should stop and check your

tires as soon as possible, and

inflate them to the proper pres-

sure. Driving on a significantly

under-inflated tire causes the tire

to overheat and can lead to tire

failure. Under-inflation also

reduces fuel efficiency and tire

tread life, and may affect the vehi-

cle’s handling and stopping abil-

ity.
Please note that the TPMS (tire

pressure warning system) is not a

substitute for proper tire mainte-

nance, and it is the driver’s

responsibility to maintain correct

tire pressure, even if under-infla-

tion has not reached the level to

trigger illumination of the TPMS

low tire pressure telltale (tire pres-

sure warning light).

WARNING

Your vehicle has also been

equipped with a TPMS (tire pres-

sure warning system) malfunc-

tion indicator to indicate when the

system is not operating properly.

The TPMS (tire pressure warning

system) malfunction indicator is

combined with the low tire pres-

sure telltale (tire pressure warning

light). When the system detects a

malfunction, the telltale will flash

for approximately one minute and

then remain continuously illumi-

nated. This sequence will con-

tinue upon subsequent vehicle

start-ups as long as the malfunc-

tion exists. When the malfunction

indicator is illuminated, the sys-

tem may not be able to detect or

signal low tire pressure as

intended.
TPMS (tire pressure warning sys-

tem) malfunctions may occur for a

variety 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 pressure

warning system) malfunction tell-

tale after replacing one or more

tires or wheels on your vehicle to

ensure that the replacement or

alternate tires and wheels allow

the TPMS (tire pressure warning

system) to continue to function

properly.

NOTICE

■

To ensure the tire pressure

warning system operates

properly

Do not install tires with different

specifications or manufacturers

as the tire pressure warning sys-

tem may not operate properly.
