●If the ID code on the tire pressure warning valves and transmitters is
not registered.
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a large metallic object which can interfere with signal reception is
put in the trunk.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
●If non-genuine Toyota wheels are used.
●If tire chains are used.
●If the spare tire (except compact spare tire) is in a location subject to
poor radio wave signal reception.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
■If the tire pressure warning light comes on after blinking for 1
