8-2. Steps to take in an emergency

If you have a flat tire (vehicles without a spare tire)

Your vehicle is not equipped with a spare tire, but instead is equipped with an
emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire tread can be
repaired temporarily with the emergency tire puncture repair kit.

WARNING

■

If you have a flat tire

Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the wheel beyond

repair, which could result in an accident.

play the actual tire inflation pres-
sure about 1 minute after the
switch is turned on.

• Turn the compressor switch off

and then check the tire infla-
tion pressure. Being careful
not to over inflate, check and
repeat the inflation procedure

■

Emergency tire puncture repair kit

●

The sealant has a limited lifespan. The expiry date is marked on the bottle. The sealant

should be replaced before the expiry date. Contact any authorized Lexus retailer or

Lexus authorized repairer, or any reliable repairer for replacement.

●

The sealant stored in the emergency tire puncture repair kit can be used only once to

temporarily repair a single tire. If the sealant in the bottle and other parts of the kit have

been used and need to be replaced, contact any authorized Lexus retailer or Lexus

authorized repairer, or any reliable repairer.

●

The sealant can be used when the outside temperature is from -30



C (-22



F) to 60



C

(140



F).

●

The kit is exclusively designed for size and type of tires originally installed on your vehi-

cle. 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. Immediately wipe away the sealant with a wet

cloth.

●

During operation of the kit, a loud operation noise is produced. This does not indicate a

malfunction.

■

If the tire is inflated to more than the recommended level

Disconnect the hose from the valve.

Disconnect the hose from the valve, remove the air release cap from the hose and then

reconnect the hose.
Turn the compressor switch on and wait for several seconds, then turn it off. Check that

the air pressure indicator shows the recommended level. (



P. 738)

If the air pressure is lower than the recommended level, turn the compressor switch on

again and repeat the inflation procedure until the recommended pressure is reached.

Install the air release cap to the end of the

hose and push the protrusion on the air

release cap into the valve to let some air out.

WARNING

■

Precautions for use of the sealant

●

Ingesting the sealant is hazardous to your health. If you ingest sealant, consume as

much water as possible, 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.

■

When fixing the flat tire

●

Stop your vehicle in a safe and flat area.

●

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 or sealant

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.

●

Keep back from the tire while it is being repaired, as there is a chance of it bursting

while the repair operation is being performed. If you notice any cracks or deforma-

tion of the tire, turn off the compressor switch and stop the repair operation immedi-

ately.

●

The kit may overheat if operated for a long period of time. Do not operate the com-

pressor continuously for more than 10 minutes.

●

Parts of the kit become hot during operation. Be careful handling the kit during and

after operation.

●

Do not attach the vehicle speed warning sticker to an area other than the one indi-

cated. 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 air bag from operating properly.

■

Driving to spread the liquid sealant evenly

●

Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-

nering.

●

If the vehicle does not drive straight or you feel a pull through the steering wheel, stop

the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.

• Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm

2

 or bar, 19 psi)

or below, this may indicate severe tire damage.

8-2. Steps to take in an emergency

NOTICE

■

When performing an emergency repair

●

Perform the emergency repair without removing the nail or screw that has punctured

the tread of the tire. If the object that has punctured the tire is removed, repair by the

emergency tire puncture repair kit may not be possible.

●

The kit is not waterproof. Make sure that the kit is not exposed to water, such as when

it is being used in the rain.

●

Do not put the kit directly onto dusty ground such as sand at the side of the road. If the

kit vacuums up dust etc., a malfunction may occur.

●

Use the kit with the top facing upward. The kit cannot work properly if it is laid on its

side.

■

Handling the emergency tire puncture repair kit

●

The compressor power source should be 12 V DC suitable for vehicle use. Do not

connect the compressor to any other source.

●

If gasoline splatters on the kit, the kit may deteriorate. Take care not to allow gasoline

to contact it.

●

Store the kit in its assigned place out of reach of children.

●

Do not disassemble or modify the 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 warning valve and trans-

mitter may not operate properly. If a liquid sealant is used, contact any authorized

Lexus retailer or Lexus authorized repairer, or any reliable repairer 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 repairing or replacing the tire.
