To inject the sealant and inflate the
tire, turn the compressor switch on.

Inflate the tire until the recom-
mended pressure is reached.

The sealant will be injected and the
pressure will spike to between 300
kPa (3.0 kgf/cm

or bar, 44 psi)

and 400 kPa (4.0 kgf/cm

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.
If the tire inflation pressure is still lower than

the recommended level after inflation for

25 minutes with the switch on, the tire is

too damaged to be repaired. Turn the com-

pressor switch off and contact any author-

ized Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

With the compressor switch off, dis-
connect the hose from the valve on
the tire and then pull out the power
plug from the power outlet socket.

Some sealant may leak when the hose is

removed.

Install the valve cap onto the valve
of the emergency repaired tire.

Attach the air release cap to the
end of the hose.

If the air release cap is not attached, the

sealant may leak and the vehicle may get

dirty.

Temporarily store the bottle in the
luggage compartment while it is
connected to the compressor.

To spread the liquid sealant evenly
within the tire, immediately drive
safety for about 5 km (3 miles)
below 80 km/h (50 mph).

After driving, stop your vehicle in a
safe place on a hard, flat surface
and reconnect the compressor.

Turn the compressor switch on and
wait for several seconds, then turn it
off. Check the tire inflation pres-
sure.

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.

438

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

●
