If the tire pressure warning system is not functioning
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with 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 tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies are
nearby
●If a radio set at a similar frequency is in use in the vehicle
●If a window tint that affects the radio wave signals is installed
●If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings
●If non-genuine Toyota wheels are used (Even if you use Toyota wheels,
the tire pressure warning system may not work properly with some types
of tires.)
●If tire chains are used
■The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the power switch to off during initializa-
tion, it is not necessary to press the reset switch again as initialization
will restart automatically when the power switch has been turned to the
ON mode for the next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and conduct initialization again.
■When the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to record tire inflation pressure settings
are unsuccessful, have the vehicle inspected by your Toyota dealer.
●When operating the tire pressure wa rning reset switch, the tire pressure
warning light does not blink 3 times.
●After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.
