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.
■
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
●
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.
■
Selectable Color Trim (if equipped)
●
If rattles, noise, or other problems occur while
Selectable Color Trim are installed, contact
your Lexus dealer.
●
Do not remove or install Selectable Color
Trim yourself, as it may be damaged. Have the
Selectable Color Trim removed and installed
by your Lexus dealer.
