■Warning performance of the tire
pressure warning system
●When performing the tire pressure
setting using the current tire infla-
tion pressure, the warning timing
of the tire pressu re warning sys-
tem will vary accor ding to the con-
ditions under which tire pressure
setting was performed. Therefore,
a warning may be output even if
the tire inflation pressure drops
slightly or if the tire inflation pres-
sure increases above that when
the tire inflation pressure was set.
●Make sure to perform the tire
pressure setting procedure after
adjusting the tire inflation pres-
sure. Also, make sure the tires are
cold before performing the tire
pressure setting procedure or
adjusting the tire inflation pres-
sure.
■Tire inflation pressure setting
procedure
●If the power switch is turned off
while setting the tir e inflation pres-
sure, the next time the power
switch is turned to ON, the setting
procedure will resume and it will
not be necessary to restart the
procedure.
●If the tire inflation pressure setting
procedure is started unnecessar-
ily, adjust the tire inflation pres-
sure to the specified level with the
tires cold and then perform setting
by selecting a specified tire infla-
tion pressure, or perform the tire
inflation pressure setting proce-
dure with the curren t tire inflation
pressure.
■If the tire inflation pressure can-
not be set easily
●Normally, the tire inflation pres-
sure setting pro cedure can be
completed in 2 or 3 minutes.
●If the tire pressur e warning light
does not blink 3 times when start-
ing the tire inflation pressure set-
ting procedure, t he procedure
may not have started. Perform the
procedure again from the begin-
ning.
●If tire inflation pressure setting
procedure cannot be completed
after performing the above proce-
dure, contact your Toyota dealer.

a unique ID code. When new
tire pressure warning valves and
transmitters are installed, new
ID codes must be registered in
