7-2. Steps to take in an emergency

WARNING

●

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 com-

pleted, 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 procedure is 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 kit may overheat if operated for a

long period of time. Do not operate

the compressor continuously for more

than 35 minutes.

●

Parts of the kit become hot during

operation. Be careful handling the kit

during and after operation. Do not

touch the metal part around the con-

necting area between the bottle and

compressor. It will be extremely hot.

●

Do not attach the vehicle speed warn-

ing 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

●

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 sepa-

rated 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.

NOTICE

■

When performing an emergency

repair

●

Perform the emergency repair with-

out 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 possi-

ble.

●

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.

●

Make sure to stand the kit with the bot-

tle vertical. The kit cannot work prop-

erly if it is laid on its side.

■

Handling the emergency tire punc-

ture repair kit
