●
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 kit, a loud opera-
tion noise is produced. This does not indi-
cate a malfunction.
●
Do not use the emergency tire puncture
repair kit to check or to adjust the tire
pressure.
■
Note for checking the emergency tire
puncture repair kit
Check the sealant expiry date occasionally.

WARNING
■
When fixing the flat tire
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●
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.
320
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 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 19 psi (130 kPa, 1.3 kgf/cm
2
or bar) 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.
