NOTICE
Do not use liquid sealants for a flat tire as air pressure
sensors will be damaged.
When the tires must be repaired or replaced, have
them repaired or replaced by the nearest Lexus
dealer or authorized tire dealer. The tire pressure
sensors will be affected by the installation or removal
of tires.
When the tires must be replaced, replace the
grommets for air pressure sensors as well.
System malfunction
The warning light comes on if the system does not work
properly.
The system will be disabled in the conditions below:
Electric devices or facilities using similar radio wave
frequencies are nearby.
If a radio set at similar frequencies is in use.
Much snowflakes or ice gets on the vehicle, in particular,
around the wheels or wheel housings.
The sensor battery is expired.
The tires not equipped with air pressure sensor are used.
Although the tires are equipped with air pressure sensors,
the selector switch (see page 224) is set to other tire setting.
CAUTION
The use of non−genuine wheels will cause the air
pressure sensors to transmit the electronic code in
different manner, resulting in the failure of the
system.
The use of different type of tires with genuine wheels
may also cause the malfunction of the system.
INFORMATION
If the chains are installed, the air pressure warning
system may not operate properly.
