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.

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

When having the tire repaired or

replaced, make sure to tell your

Toyota dealer that the sealant is

injected.

■When fixing the flat tire

●Stop your vehicle in a safe and

flat area.

●Do not touch the wheels or the

area around the brakes immedi-

ately after the vehicle has been

driven.

After the vehicle has been

driven, the wheels and the area

around the brakes may be

extremely hot. Touching these

areas with hands, feet or other

body parts may result in burns.

■If the tire is inflated to more

than the specified air pressure

1 Disconnect the hose from the

valve.

2 Install the air release cap to the

end of the hose and push the

protrusion on the air release cap

into the tire valve to let some air

out.

●Connect the valve and hose

securely with the tire installed

on the vehicle. If the hose is not

properly connected to the valve,

air leakage may occur as seal-

ant may be sprayed out.

●If the hose comes off the valve

while inflating the tire, there is a

risk that the hose will move

abruptly due to air pressure.

3 Disconnect the hose from the

valve, remove the air release cap

from the hose and then recon-

nect the hose.

4 Turn the compressor switch on

and wait for several seconds,

and then turn it off. Check that

the air pressure indicator shows

the specified air pressure.

●After inflation of the tire has

completed, the sealant may

splatter when the hose is dis-

connected or some air is let out

of the tire.

●Follow the operation procedure

to repair the tire. If the proce-

dures not followed, the sealant

may spray out.

If the air pressure is under the des-

ignated pressure, turn the compres-

sor switch on again and repeat the

inflation procedure until the speci-

fied air pressure is reached.

●Keep back from the tire while it

is being repaired, as there is a

chance of it bursting while the

repair operation is being per-

formed. If you notice any cracks

or deformation of the tire, turn

off the compressor switch and

stop the repair operation imme-

diately.

■After a tire is repaired with the

emergency tire puncture repair

kit

●The tire pressure warning valve

and transmitter should be

replaced.

●Even if the tire inflation pressure is

at the recommended level, the tire

pressure warning light may come

on/flash.

583

8-2. Steps to take in an emergency

WARNING

NOTICE

●The repair kit may overheat if

operated for a long period of

time. Do not operate the repair

kit continuously for more than

40 minutes.

■When performing an emer-

gency repair

●A tire should only be repaired

with the emergency tire punc-

ture repair kit if the damage is

caused by a sharp object such

as nail or screw passing through

the tire tread.

Do not remove the sharp object

from the tire. Removing the

object may widen the opening

and disenable emergency repair

with the repair kit.

●Parts of the repair kit become

hot during operation. Be careful

handling the repair kit during

and after operation. Do not

touch the metal part connecting

the bottle and the compressor. It

will be extremely hot.

●Do not attach the vehicle speed

warning sticker to an area other

than the one indicated. If the

sticker is attached to an area

where an SRS airbag is located,

such as the pad of the steering

wheel, it may prevent the SRS

airbag from operating properly.

●The repair kit is not waterproof.

Make sure that the repair kit is

not exposed to water, such as

when it is being used in the rain.

●Do not put the repair kit directly

onto dusty ground such as sand

at the side of the road. If the

repair kit vacuums up dust etc.,

a malfunction may occur.

■Driving to spread the liquid

sealant evenly

Observe the following precautions

to reduce the risk of accidents.

●Make sure to stand the kit with

the bottle vertical. The kit can-

not work properly if it is laid on

its side.

Failing to do so may result in a

loss of vehicle control and cause

death or serious injury.

■Precautions for the emer-

gency tire puncture repair kit

●Drive the vehicle carefully at a

low speed. Be especially careful

when turning and cornering.

●The repair kit power source

should be 12 V DC suitable for

vehicle use. Do not connect the

repair kit to any other source.

8

●If the vehicle does not drive

straight or you feel a pull

through the steering wheel, stop

the vehicle and check the fol-

lowing.

●If fuel splatters on the repair kit,

the repair kit may deteriorate.

Take care not to allow fuel to

contact it.

• Tire condition. The tire may

have separated from the wheel.

●Place the repair kit in a storage

to prevent it from being exposed

to dirt or water.

• Tire inflation pressure. If the tire

inflation pressure is 19 psi (130

WARNING

■When attempting to free a

stuck vehicle

If you choose to push the vehicle

back and forth to free it, make

sure the surrounding area is clear

to avoid striking other vehicles,

objects or people. The vehicle

may also lunge forward or lunge

back suddenly as it becomes free.

Use extreme caution.

position with the accelerator pedal

depressed.

This may lead to unexpected

rapid acceleration of the vehicle

that may cause an accident

resulting in death or serious

injury.

NOTICE

mission and other compo-

nents

●Avoid spinning the wheels and

depressing the accelerator

pedal more than necessary.

●If the vehicle remains stuck

even after these procedures are

performed, the vehicle may

require towing to be freed.
