WARNING
QWhen fixing the flat tire
O Stop your vehicle in a safe and flat area.
O 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 arou nd the
brakes may be extremely hot. Touching these areas with hands, f eet or
other body parts may result in burns.
O 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
as sealant may be sprayed out.
O 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.
O 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.
O Follow the operation procedure to repair the tire. If the procedures not fol-
lowed, the sealant may spray out.
O 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 swit ch and stop
the repair operation immediately.
O 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.
O Parts of the repair kit become hot during operation. Be careful handling the
repair kit during and after operation. Do not touch the metal p art connect-
ing the bottle and the compressor. It will be extremely hot.
O 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 S RS airbag is
located, such as the pad of the steering wheel, it may prevent the SRS air-
bag from operating properly.
