When replacing wheels
The wheels of your Lexus are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advanced warning in
the event of a loss in tire inflation pressure. Whenever wheels are replaced, the tire
pressure warning valves and tran smitters must be installed. (  P. 767)
CAUTION■
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 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.■
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 acci-
dent.
NOTICE■
Replacing tire pressure warning valves and transmitters ●
Because tire repair or re placement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Le xus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitte rs at your Lexus dealer.●
Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valv es and transmitters may not work properly with non-
genuine wheels.
