If the tire pressure warning light blinks when the ignition
switch is turned to the “ON” position, the tire pressure
warning system is not working properly.
The system will be disabled in the following conditions:
(When the condition becomes normal, the system will work
properly.)
D If tires not equipped with tire pressure warning valves and
transmitters are used.
D If the ID code on the tire pressure warning valves and
transmitters is not registered.
D If electronic devices or facilities using similar radio wave
frequencies are nearby.
D If a radio set at similar frequencies is in use in the vehicle.
D If a window tint that affects the radio wave signals is
installed.
D If the tire pressure warning select switch is set to a different
tire setting.
D If there is a lot of snow or ice on the vehicle, in particular
around the wheels or wheel housings.
D If non−genuine Lexus wheels are used.
D If tire chains are used.
D If the spare tire is in a location subject to poor radio wave
signal reception.

2
or bar,
73 psi) or higher.
If the tire pressure warning light blinks frequently when the
ignition switch is turned to the “ON” position, have it checked
by your Lexus dealer.
Even if you use genuine wheels, the tire pressure warning
system may not work properly with some types of tires.
Pushing the tire pressure warning reset switch should not turn
off the tire pressure warning light.
