WARNING
QDo not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the t ire and the
wheel beyond repair.
Driving with a flat tire may cause a circumferential groove on the side wall.
In such a case, the tire may e xplode when using a repair kit.
Q Caution while driving
O Store the repair kit in the luggage compartment.
Injuries may result in the event of an accident or sudden braki ng.
O The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
O Do not use repair kit for tires that are different size than the original ones,
or for any other purpose. If the tires have not been completely repaired, it
could lead to an accident caus ing death or serious injury.
Q Precautions for use of the sealant
O 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.
O If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.

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.

When trouble arises
WARNING
QDriving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of acciden ts.
Failing to do so may result in a loss of vehicle control and ca use death or
serious injury.
O Drive the vehicle carefully at a low speed. Be especially careful when turn-
ing and cornering.
O 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 the tire inflation pressure is 130 kPa (1.3 kgf/cm2
or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
QWhen performing an emergency repair
O 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 pa ssing
through the tire tread.
Do not remove the sharp object from the tire. Removing the obje ct may
widen the opening and disenable em ergency repair with the repair kit.
O 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.
O 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 mal function may
occur.
O Make sure the sealant bottle of the repair kit is in a vertical position. The
repair kit does not operate properly when it is laid.
Q Precautions for the emergency tire puncture repair kit
O The repair kit power source should be 12 V DC suitable for vehicle use. Do
not connect the repair kit to any other source.
O If fuel splatters on the repair kit, the repair kit may deteriorate. Take care
not to allow fuel to contact it.
O Place the repair kit in a storage to prevent it from being exposed to dirt or
water.
O Store the repair kit in the luggage compartment out of reach of children.
O Do not disassemble or modify the repair kit. Do not subject parts such as
the air pressure indicator to impacts. This may cause a malfunc tion.
