6-3. Do-it-yourself maintenance
● 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
Vehicles with a tire inflation pressure display function: If tire position
information is not correctly 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.
■

Initialization procedure

● Make sure to perform the initialization procedure after adjusting the tire
inflation pressure.
Also, make sure the tires are cold before performing the initialization
procedure or adjusting the tire inflation pressure.
● If the engine switch is turned to the "LOCK" position (vehicles without a
smart key system) or off (vehicles with a smart key system) during ini-
tialization, it is not necessary to restart the initialization procedure from
the beginning as it will begin automatically when the engine switch is
turned back to the "ON" position (vehicles without a smart key system)
or IGNITION ON mode (vehicles with a smart key system).
● If initialization has accidentally been started when it is not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold and then perform the initialization procedure again.
● Vehicles with a tire inflation pressure display function: While the position
of each tire is being determined and the inflation pressures are not being
displayed on the multi-information display, if the inflation pressure of a
tire drops, the tire pressure warning light will come on.

Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accor-
dance with the conditions under which it was initialized. 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.
