6-3. Do-it-yourself maintenance
also take a few minutes to display the
tire inflation pressure after inflation pressure has been adjusted.
●Tire inflation pressure changes with temperature. The displayed values may also be different from the values
measured using a tire pressure gauge.
■Situations in which the tire pres-sure warning system may not oper-
ate properly
●In the following cases, the tire pres-
sure warning system may not operate properly.• If non-genuine Toyota wheels are
used. • A tire has been replaced with a tire that is not an OE (Original Equipment)
tire. • A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped. • An auxiliary-supported run-flat tire is equipped.
• 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 the tire inflation pressure is
extremely higher than the specified level.• 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.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-play, airport or other facility that gen-
erates strong radio waves or electrical noise.• When carrying a portable radio, cellu-
lar phone, cordless phone or other wireless communication device.
●When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning
system will change in accordance with driving conditions. 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.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
Have tire pressure warning valves
and transmitter ID codes regis-
tered any authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer. ( P.339)
■Replacing tires and wheels
If the ID code of the tire pressure warn-
ing valve and transmitter is not regis- tered, the tire pressure warning system will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunc-
tion.

ing valves and transmitters
