When replacing wheels (vehicles with the tire pressure warning system)
■
The wheels of your vehicle are equipped with tire pressure warning valves and transmit-
ters that allow the tire pressure warning system to provide advance warning in the event
of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning
valves and transmitters must be installed. (P. 475)
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.
GS350 F SPORT models: 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 resulting in 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 accident.
NOTICE
Replacing tire pressure warning valves and transmitters (vehicles with the tire pres-
■
sure warning system)
Because tire repair or replacement may affect the tire pressure warning valves and
●
transmitters, make sure to have tires serviced by your Lexus dealer or other qualified
service shop. In addition, make sure to purchase your tire pressure warning valves
and transmitters at your Lexus dealer.
Ensure that only genuine Lexus wheels are used on your vehicle.
●
Tire pressure warning valves and transmitters may not work properly with non-genu-
ine wheels.
