reached.

• The tire can be inflated for about 5 to 20 minutes (depending on

the outside temperature). If the tire inflation pressure is still lower
than the specified point after inflation for 25 minutes, the tire is
too damaged to be repaired. Turn the compressor switch off and
contact your Toyota dealer.

• If the tire inflation pressure exceeds the specified air pressure, let

out some air to adjust the tire inflation pressure. (

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 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, con-

tact your Toyota dealer.

●

The compressor can be used repeatedly.

●

The sealant can be used when the outside temperature is from -40°F

(-40°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. Immediately wipe

away the sealant with a wet cloth.

●

During operation of the repair kit, a loud operation noise is produced.

This does not indicate a malfunction.

●

Do not use to check or to adjust the tire pressure.

WARNING

■

Do not drive the vehicle with 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.
Driving with a flat tire may cause a circumferential groove on the side

wall. In such a case, the tire may explode when using a repair kit.

■

Caution while driving

●

Store the repair kit in the luggage compartment.

Injuries may result in the event of an accident or sudden braking.

●

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 serious 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 causing death or serious injury.

■

Precautions for use of the sealant

●

Ingesting the sealant is hazardous 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 discomfort persists, consult a doctor.

WARNING

■

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 immediately

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 vehi-

cle. If the hose is not properly connected to the valve, air leakage may

occur as 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 disconnected or some air is let out of the tire.

●

Follow the operation procedure to repair the tire. If the procedures 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 performed. If you

notice any cracks or deformation of the tire, turn off the compressor

switch and stop the repair operation immediately.

●

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.

WARNING

■

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 following.
• 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 emergency repair

●

A tire should only be repaired with the emergency tire puncture 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 emergency 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 luggage compartment out of reach of chil-

dren.

●

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.
