WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommended in the Owner’s
Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing
so may result in an accident, causing death or serious injury.
●Do not install steel wheels.
The wheel contact surface could be damaged, and the wheel could come off while
driving, which could lead to an accident re sulting in death or serious injury. (except
for GS200t with steel spare wheel)
■Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an accident.
NOTICE

sure warning system)
●Because tire repair or replacement may affe ct the tire pressure warning valves and
transmitters, make sure to have tires se rviced by any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer or other qualified service shop. In
addition, make sure to purchase your tire pressure warning valves and transmitters at
any authorized Lexus retailer or Lexus auth orized repairer, or any reliable repairer.
●Ensure that only genuine Lexus wheels are used on your vehicle.

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 r emoved, repair by the
emergency tire puncture repair kit may not be possible.
●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.
■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.
●Store the emergency tire puncture repair kit in the trunk.
The kit may be thrown around during sudden braking and so forth, damaging the kit.
●Store the repair kit in the trunk out of reach of children.
●Do not disassemble or modify the repair kit. Do not subject parts such as the air pres-
sure indicator to impacts. This may cause a malfunction.
■To avoid damage to the tire pressure warning valves and transmitters (vehicles with
the tire pressure warning system)
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 any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer or other qualified
