If the tire is inflated to more than the recommended level
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap from the
hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, and then turn
it off. Check that the air pressure indicator shows the recommended level.
(P. 936)
If the air pressure is lower than the recommended level, turn the compres-
sor switch on again and repeat the inflation procedure until the recom-
mended pressure is reached.
The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repair kit, the valve
should be replaced.
After a tire is repaired with the emergency tire puncture repair kit, even if
the tire inflation pressure is at the recommended level, the tire pressure
warning light may come on/flash.
Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle.
Do not use sealant whose expiry date has already passed. Otherwise, repairs
conducted using the emergency tire puncture repair kit may not be performed
properly.Install the air release cap to the end of
the hose and push the protrusion on the
air release cap into the tire valve to let
some air out.

CAUTION
Precautions for use of the sealant
Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a doc-
tor.
If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
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 procedures 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 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 operation. Be careful handling
the repair kit during and after operation. Do not touch the metal part con-
necting 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 air
bag from operating properly.

CAUTION
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 less, the tire may be severely damaged.
NOTICE
When performing an emergency repair
Perform the emergency repair without 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 pos-
sible.
The repair kit is not waterproof. Make 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.
