Repairing or replacing tires, wheels, tire pressure warning valves, transmitters

and tire valve caps

When removing or fitting the wheels, tires or the tire pressure warning valves and

transmitters, contact your Lexus dealer as the tire pressure warning valves and

transmitters may be damaged if not handled correctly.

Make sure to install the tire valve caps. If the tire valve caps are not installed,

water could enter the tire pressure warning valves and the tire pressure warning

valves could be bound.

When replacing tire valve caps, do not use tire valve caps other than those speci-

fied. The cap may become stuck.

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 your Lexus

dealer or other qualified service shop as soon as possible. Make sure to replace

the tire pressure warning valve and transmitter when replacing the tire. (P. 644)

Take particular care when driving on roads with loose surfaces or potholes.

These conditions may cause losses in tire inflation pressure, reducing the cushion-

ing ability of the tires. In addition, driving on rough roads may cause damage to the

tires themselves, as well as the vehicle' s wheels and body.

Low profile tires (except 225/50R17 tires)

Low profile tires may cause greater damage than usual to the tire wheel when sus-

taining impact from the road surface. Therefore, pay attention to the following:

Be sure to use proper tire inflation pressure. If tires are under-inflated, they may

be damaged more severely.

Avoid potholes, uneven pavement, curbs and other road hazards. Failure to do so

may lead to severe tire and wheel damage.

If tire inflation pressure of each tire becomes low while driving

Do not continue driving, or your tires and/or wheels may be ruined.
