WARNING
■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 19 psi (130 kPa, 1.3 kgf/cm

NOTICE
■When performing an emergency repair
●Perform the emergency repair without removi ng 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

●The repair kit is not waterproof. Make sure that the repair kit is not exposed to water,
such as when it is be ing 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.
■Handling the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle use. Do not con-
nect the repair kit to any other source.
●If gasoline splatters on the repair kit, the repair kit may deteriorate. Take care not to
allow gasoline to contact it.

The kit may be thrown around during sudden braking and so forth, damaging the kit.
●Store the repair kit in the tr unk out of reach of children.

sure indicator to impacts. This may cause a malfunction.

When a tire is repaired with liquid sealants, the tire pressure warning valve and trans-
mitter may not operate properly. If a liquid sealant is used, contact your Lexus dealer or
other qualified service shop as soon as possi ble. Make sure to replace the tire pressure
warning valve and transmitter when replacing the tire. ( P. 395)
