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 beextremely 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.
●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 completed, the sealant may splatter when the hose is dis-connected 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 operation is being performe d. If you notice any cracks or deforma-
tion of the tire, turn off the compressor switch and stop the repair operation immedi- ately.
●The repair kit may overheat if operated for a long period of time. Do not operate the
repair kit continuously for more than 35 minutes.
●Parts of the repair kit become hot during op eration. 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 indi- cated. 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 air bag from operating properly.
■Driving to spread the liquid sealant evenly
●Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-
nering.
●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 separated from the wheel. • Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm2 or b ar, 1 9 p si)or less, the tire may be severely damaged.
