Tire pressure warning system

The tire pressure warning system warns

you that the tire inflation pressure is

low.

The tire pressure warning light comes on

when the engine switch is in “ON” position

and goes off after a few seconds. This

means the tire pressure warning system is

operating properly. If the tire inflation pres-

sure becomes low, the light comes on

again. In this case, adjusting the tire infla-

tion pressure will turn off the light after a

few minutes. If the light comes on after

a substitute for checking normal tire infla-

tion pressure. Check the tire inflation

pressure with a tire pressure gauge regu-

larly.

The tire pressure warning light may turn

on due to natural causes such as natural

air leaks or tire inflation pressure changes

caused by temperature. In this case, ad-

justing the tire inflation pressure will turn

off the light after a few minutes.

CAUTION

If the tire pressure warning light

comes on, be sure to observe the

following precautions. Failure to do

so could cause loss of vehicle control

and result in death or serious injury.

Each tire, including the spare (if pro-

vided), 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 different 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 infla-

tion pressure for those tires.)

The spare tire is also equipped with the

tire pressure warning valve and transmit-

ter. The tire pressure waning light will turn

on if the tire inflation pressure of the

spare tire is low. If a tire goes flat, even

though the flat tire is replaced with the

spare tire, the warning light does not turn

off. Replace the spare tire with the re-

paired tire and adjust the proper tire infla-

tion pressure. The tire pressure warning

light will turn off after a few minutes.

D Stop your vehicle in a safe place as

soon as possible. Adjust the tire

inflation pressure immediately.

D If the tire pressure waring light

comes on even after tire inflation

pressure adjustment, it is probable

that you have a flat tire. Check the

tires. If the tire is flat, change to

the spare tire and have the flat tire

repaired by the nearest Toyota deal-

er.

D Avoid abrupt maneuvering and brak-

ing. If the vehicle tires deteriorate,

you could lose control of the steer-

ing wheel or the brakes.

As an added safety feature, your ve-

hicle has been equipped with a tire

pressure monitoring system (TPMS−

tire pressure warning system) that il-

luminates 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 pressure. Driving on a sig-

nificantly under−inflated tire causes

the tire to overheat and can lead to

tire failure. Under−inflation also re-

duces fuel efficiency and tire tread

life, and may affect the vehicle’s han-

dling and stopping ability.

Your vehicle has also been equipped

with a TPMS (tire pressure warning

system) malfunction indicator to indi-

cate when the system is not operat-

ing properly. The TPMS (tire pressure

warning system) malfunction indicator

is combined with the low tire pres-

sure telltale (tire pressure warning

TPMS (tire pressure warning system)

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 sys-

tem) from functioning properly. Al-

ways check the TPMS (tire pressure

warning system) malfunction telltale

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 func-

tion properly.

light). When the system detects

malfunction, the telltale will flash for

approximately one minute and then

remain continuously illuminated. This

sequence will continue upon subse-

quent vehicle start−ups as long as

the malfunction exists. When the mal-

function indicator is illuminated, the

system may not be able to detect or

signal low tire pressure as intended.

NOTICE

z Do not use liquid sealants for a flat

tire as tire pressure warning valve

and transmitter will be damaged.

Please note that the TPMS (tire pres-

sure warning system) is not a substi-

tute for proper tire maintenance, and

it is the driver’s responsibility to

maintain correct tire pressure, even if

under−inflation has not reached the

level to trigger illumination of the

TPMS low tire pressure telltale (tire

pressure warning light).

z When the tires must be repaired or

replaced, have them repaired or re-

placed by the nearest Toyota dealer

or an authorized tire dealer. The

tire pressure warning valves and

transmitters will be affected by the

installation or removal of tires.
