• If the tire inflation pressure is
extremely higher than the specified
level.
• If wheels without tire pressure warning
valves and transmitters are used.
• If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
computer.
• 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.

Performance may be affected in the
following situations.
• Near a TV tower, electric power plant,
gas station, radio station, large dis-

noise
• When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device
• If tire position information is not cor-
rectly displayed due to the radio wave
conditions, the display may be cor-
rected by driving and changing the
radio wave conditions.
● When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.

When tire inflation pressure declines
rapidly for example when a tire has
burst, the warning may not function.
■ Warning performance of the tire
pressure warning system
The warning of the tire pressure warning
system will change in accordance with
the conditions under which it was initial-
ized. For this reason, the system may
give a warning even if the tire pressure
does not reach a low enough level, or if
the pressure is higher than the pressure
that was adjusted to when the system
was initialized.
Installing tire pressure warn-
ing valves and transmitters
(if equipped)
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
