Note for checking the emer-

gency tire puncture repair kit

Check the sealant expiry date occa-

sionally.

The expiry date is shown on the bot-

tle. Do not use sealant whose expiry

date has already passed. Other-

wise, repairs conducted using the

emergency tire puncture repair kit

may not be performed properly.

■

Emergency tire puncture repair

kit

●

The emergency tire puncture

repair kit is for filling the car tire

with air.

●

The sealant has a limited life

span. The expiry date is marked

on the bottle. The sealant should

be replaced before the expiry

date. Contact your Toyota dealer

for replacement.

●

The sealant stored in the emer-

gency 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

your Toyota dealer. The compres-

sor is reusable.

●

The sealant can be used when the

outside temperature is from -22°F

(-30°C) to 140°F (60°C).

●

The 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.

●

If the sealant gets on your clothes,

it may stain.

●

If the sealant adheres to a wheel

or the surface of the vehicle body,

the stain may not be removable if

it is not cleaned at once. Immedi-

ately wipe away the sealant with a

wet cloth.

●

During operation of the repair kit,

a loud operation noise is pro-

duced. This does not indicate a

malfunction.

●

Do not use to check or to adjust

the tire pressure.

WARNING

■

Caution while driving

●

Store the repair kit in the lug-

gage compartment.

Injuries may result in the event

of an accident or sudden brak-

ing.

●

The repair kit is exclusively only

for your vehicle.

Do not use repair kit on other

vehicles, which could lead to an

accident causing death or seri-

ous injury.

●

Do not use repair kit for tires

that are different size than the

original ones, or for any other

purpose. If the tires have not

been completely repaired, it

could lead to an accident caus-

ing death or serious injury.

■

Precautions for use of the

sealant

●

Ingesting the sealant is hazard-

ous to your health. If you ingest

sealant, consume as much

water as possible, and then

immediately consult a doctor.

●

If sealant gets in eyes or

adheres to skin, immediately

wash it off with water. If discom-

fort persists, consult a doctor.

478

8-2. Steps to take in an emergency

■

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.

●

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.

●

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.

●

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.

●

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.

●

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.

■

Driving to spread the liquid

sealant evenly

Observe the following precautions

to reduce the risk of accidents.
Failing to do so may result in a

loss of vehicle control and cause

death or serious injury.

●

Drive the vehicle carefully at a

low speed. Be especially careful

when turning and cornering.

●

If the vehicle does not drive

straight or you feel a pull

through the steering wheel, stop

the vehicle and check the fol-

lowing.

WARNING

• Tire condition. The tire may

have separated from the wheel.

• Tire inflation pressure. If the tire

inflation pressure is 19 psi (130

kPa, 1.3 kgf/cm

or bar) or less,

the tire may be severely dam-

aged.

NOTICE

■

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.

●

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.

■

Precautions for the emer-

gency tire puncture repair kit

●

The repair kit power source

should be 12 V DC suitable for

vehicle use. Do not connect the

repair kit to any other source.

●

If fuel splatters on the repair kit,

the repair kit may deteriorate.

Take care not to allow fuel to

contact it.

●

Place the repair kit in a storage

to prevent it from being exposed

to dirt or water.

●

Store the repair kit in the lug-

gage compartment out of reach

of children.

●

Do not disassemble or modify

the repair kit. Do not subject

parts such as the air pressure

indicator to impacts. This may

cause a malfunction.

■

To avoid damage to the tire

pressure warning valves and

transmitters

When a tire is repaired with liquid

sealants, the tire pressure warn-

ing valve and transmitter may not

operate properly. If a liquid seal-

ant is used, contact your Toyota

dealer or other qualified service

shop as soon as possible. After

use of liquid sealant, make sure to

replace the tire pressure warning

valve and transmitter when repair-

ing or replacing the tire. (
