NOTICE

■

Repairing or replacing tires, wheels, tire pressure warning valves and transmit-

ters and tire valve caps

●

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

transmitter, contact your Lexus dealer as the tire pressure warning valve and

transmitter may be damaged if not handled correctly.

●

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

fied. The cap may become stuck.

■

To avoid damaging the tire pressure warning valves and transmitters

Do not use liquid sealants on flat tires.

■

Driving on rough roads

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

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

receiving 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 pavements, curbs and other road hazards. Failure to do

so can lead to severe tire and wheel damage.

■

If tire inflation pressures become low while driving

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