When trouble arises
GS350/250_EE (OM30C36E)
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 kit is not waterproof. Make sure that the kit is not exposed to water,
such as when it is being used in the rain.
Do not put the kit directly onto dusty ground such as sand at the side of
the road. If the kit vacuums up dust etc., a malfunction may occur.
Use the kit with the top facing upward. The kit cannot work properly if it
is laid on its side.
Handling the emergency tire puncture repair kit
The compressor power source should be 12 V DC suitable for vehicle use.
Do not connect the compressor to any other source.
If gasoline splatters on the kit, the kit may deteriorate. Take care not to
allow gasoline to contact it.
Store the kit in its assigned place out of reach of children.
Do not disassemble or modify the kit. Do not subject parts such as the air
pressure indicator to impacts. This may cause a malfunction.
To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant is used, contact
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional as soon as possible. Make sure to replace the tire
pressure warning valve and transmitter when replacing the tire. (P. 674)
