Maintenance and care
●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 facilit y that generates strong
radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
If tire position information is not correctly displayed due to the radio
wave conditions, the display ma y be corrected by changing the l ocation
of the vehicle as the radio wa ve 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 exampl e when a
tire has burst, the warning may not operate.
■Initialization procedure
●Make sure to perform the initialization procedure after adjusti ng the tire
inflation pressure.
Also, make sure the tires are cold before performing the initia lization
procedure or adjusting the tire inflation pressure.
●If the engine switch is turned off during initialization, it is not necessary
to restart the initialization procedure from the beginning as i t will begin
automatically when the engine switch is turned back to IGNITION ON
mode.
●If initialization has accidentally been started when it is not necessary,
adjust the tire inflation pressu re to the specified level when the tires are
cold and then perform the ini tialization procedure again.
●While the position of each tire is being determined and the inf lation pres-
sures are not being displayed on the multi-information display, if the
inflation pressure of a tire drops, the tire pressure warning l ight will come
on.
■Warning performance of the tire pressure warning system
The warning of the tire pressu re warning system will change in accor-
dance with the conditions under which it was initialized. For t his reason,
the system may give a warning even if the tire pressure does no t reach a
low enough level, or if the pressure is higher than the pressur e that was
adjusted to when the sys tem was initialized.

switch off before driving the vehicle.
If the vehicle is driven after ID code registration is started, to cancel reg-
istration, perform the ID code r egistration start procedure aga in and turn
the engine switch of f before driving.
●If ID code registration has been canceled, the tire pressure wa rning light
will blink for approximately 1 mi nute when the engine switch is turned to
IGNITION ON mode and then illumina te. The tire pressure warning sys-
tem will be operational when the tire pressure warning light tu rns off.
●If the warning light does not turn off even after several minut es have
elapsed, ID code registration may not have been cancelled corre ctly. To
cancel registration, perform the ID code registration start procedure
again and then turn the engine switch off before driving.
