When trouble arises
IS300h_EE(OM53B95E)
CAUTION
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.
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 disconnected or some air is let out of the tire.
Follow the operation procedure to repair the tire. If the procedure is not fol-
lowed, 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 10 minutes.
Parts of the kit become hot during operation. Be careful handling the kit
during and after operation.
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 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 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 separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm
2 or
bar, 19 psi) or below, this may indicate severe tire damage.
