Note for checking the emergency tire

puncture repair kit

Check the sealant expiry date occasionally.

The expiry date is shown on the bottle. Do

not use sealant whose expiry date has

already passed. Otherwise, repairs con-

ducted using the emergency tire puncture

repair kit may not be performed properly.

■

Emergency tire puncture repair kit

●

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 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 has been used and needs to be

purchased, contact any authorized Lexus

retailer or Lexus authorized repairer, or

any reliable repairer. The compressor is

reusable.

●

The sealant can be used when the outside

temperature is from -40°C (-40°F) to

60°C (140°F).

●

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 kit, a loud opera-

tion noise is produced. This does not indi-

cate a malfunction.

●

Do not use to check or to adjust the tire

pressure.

or bar,

58 psi), then gradually decrease.
The air pressure gauge will display
the actual tire inflation pressure
about 1 to 5 minutes after the
switch is turned on.

Turn the compressor switch off and then

check the tire inflation pressure. Being

careful not to over inflate, check and

repeat the inflation procedure until the rec-

ommended tire inflation pressure is

reached.

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 vehicle. If

the hose is not properly connected to

the valve, air leakage may occur or

sealant may be sprayed out.

550

7-2. Steps to take in an emergency

WARNING

●

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 40 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/cm2 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 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.

●

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

●

The compressor power source should

be 12 V DC suitable for vehicle use.

Do not connect the compressor to any

other source.

●
