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 co nnected 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 abru ptly due to air pressure.
●After inflation of the tire has comp leted, 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 op eration 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 strai ght 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
2 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. Ma ke 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 repa ir 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 im pacts. This may cause a malfunction.

NOTICE
■To avoid damage to the tire pressure warning valves and transmit-
ters

as possible. After use of liquid sealant, make sure to replace the tire
pressure warning valve and transmitter when repairing or replacing the
