not operate properly even if their
power consumption is less than
1500 W:
●Devices with high initial peak watt-
age
●Measuring devices that process
precise data
●Devices that require an extremely
stable power supply

• If there is a lot of snow or ice on
the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is
much higher than the specified
level.
• If wheels not equipped with tire
pressure warning valves and
transmitter are used.
• If the ID code on the tire pressure
warning valves and transmitters is
not registered in the tire pressure
warning computer.
●Performance may be affected in
the following situations.
• When driving near a TV tower, electric power plant, gas station,
radio station, large display, airport
or other facility that generates
strong radio waves or electrical
noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication
device

rectly displayed due to the radio
wave conditions, the display may be
corrected by changing the location
of the vehicle as the radio wave
conditions may change.
●When the vehicle is stopped, the
time taken for the warning to start
or turn off may be longer.
●When the inflation pressure of a
tire drops rapidly, for example when a tire has burst, the warning
may not operate.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system w ill change in
accordance the conditions under
which it was initia lized. For this rea-
son, 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 sys-
tem was initialized.
■Tire pressure warning system
certification
 P.569
When replacing the tires or
wheels, the tire pressure warn-
ing valves and transmitters must
be installed to the wheels which
will be installed to the vehicle.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer and the tire
pressure warning system must
be initialized. ( P.422)
■Replacing tires and wheels
If the ID codes of the tire pressure
warning valves and transmitters are
not registered, the tire pressure
warning system will not work prop-
erly. In this case, after driving for
about 10 minutes, the tire pressure
warning light will blink for approxi-
mately 1 minute and then illuminate
to indicate a system malfunction.
