• If the tire inflation pressure is extremely higher than the specified level.
• If the spare tire is in a location subject to poor radio wave signal reception.
• If a large metallic object which can interfere with signal reception is put
near the spare tire.

cal noise
• When carrying a portable radio, cellular phone, cordless phone or other

burst, the warning may not function.
The initialization operation (vehicles with the tire pressure warning system)
■
Make sure to carry out initialization after adjusting the tire inflation pressure.
●
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
If you have accidentally turned the engine switch to OFF mode during initial-
●
ization, it is not necessary to press the reset switch again as initialization will
restart automatically when the engine switch has been turned IGNITION ON
mode for the next time.
If you accidentally press the reset switch when initialization is not necessary,
●
adjust the tire inflation pressure to the specified level when the tires are
cold, and conduct initialization again.
