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.

8 Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Even if the vehicle is not driven at approximately 40 km/h (25 mph) or more, initialization can be completed by
driving for a long time. However, if ini- tialization does not complete after driv-ing for 1 hour or more, park the vehicle
in a safe place for more than 15 min-
utes and please drive a vehicle once
again with the power switch ON. ( P.340)
■Initialization procedure
●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 off during initialization, it is not necessary to press the reset
switch again as initialization will restart automatically when the power switch is turned to ON 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.
●While the position of each tire is being
determined and the inflation pres- sures are not being displayed on the multi-information display, if the infla-
tion pressure of a tire drops, the tire pressure warning light will come on.
■If the tire pressure warning system is not initialized properly
●In the following situations, initialization
may take longer than usual to be com- pleted or may not be possible. (Usu-ally, the vehicle will need to be driven
for approximately 10 to 30 minutes to complete initialization.) If initialization is not complete after driving approxi-
mately 30 minutes, continue driving for a while.• If the vehicle is driven on an unpaved
road, it may take longer to complete initialization.• If the vehicle is backed up while per-
forming initialization, data collected during initialization will be cleared and it will take longer than normal to com-
plete. • If the vehicle is driven in heavy traffic or another situation where other vehi-

cles are driven close by, it may take
time for the system to recognize the tire pressure warning valve and trans-mitters of your vehicle over those of
other vehicles.
If initialization is not complete after driv-
ing for approximately 1 hour, park the
vehicle in a safe place for approximately
20 minutes and then drive the vehicle
again.
●In the following situations, initialization
will not be started or was not com- pleted properly and the system will not operate properly. Perform the initial-
ization procedure again. • If, when attempting to start initializa-tion, the tire pressure warning light
does not blink 3 times. • If, when the vehicle has been driven for about 20 minutes after performing
initialization, the tire pressure warning light blinks for approximately 1 minute and then illuminates.
●If initialization cannot be completed after performing the above procedure,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

5 Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Registration is complete when the tire
pressure warning light turns off and the inflation pressure of each tire is dis-played on the multi-information display.
Registration may take longer than approximately 1 hour in certain situa-tions, such as when the vehicle is
stopped for a long time at traffic lights, etc. ( P.340)
After registering the ID codes, make
sure to initialize the tire pressure warn- ing system. ( P.337)
■When registering ID codes
●Before performing ID code registra- tion, make sure that no wheels with tire pressure warning valve and trans-
mitters installed are near the vehicle.
●Make sure to initialize the tire pres-
sure warning system after registering the ID codes. If the system is initial-ized before registering the ID codes,
the initialized values will be invalid.
●As the tires will be warm when regis-
tration is completed, make sure to allow the tires to cool before perform-ing initialization.
■Canceling ID code registration
●To cancel ID code registration after it has been started, operate the multi-
information display to select “Identify-
ing Each Wheel & Position”. ( P.339)
●If ID code registration has been can-
celed, the tire pressure warning light will blink for approximately 1 minute when the power switch is turned to
ON mode and then illuminate. The tire pressure warning system will be oper-ational when the tire pressure warning
light turns off.
●If the warning light does not turn off
even after several minutes have elapsed, ID code registration may not have been canceled correctly. To can-
cel registration, perform the ID code registration start procedure again and then turn the power switch off before
driving.
■If ID codes are not registered prop- erly
●In the following situations, ID code registration may take longer than usual to be completed or may not be
possible. (Usually, the vehicle will need to be driven for approximately 10 to 30 minutes to complete ID code
registration.) If ID code registration is not complete after driving for approximately 30 min-
utes, continue driving for a while. • If the vehicle is driven on an unpaved road, it may take longer than normal
to complete registration. • If the vehicle is backed up while per-forming registration, data collected
during registration will be cleared, and it will take longer than normal to com-plete.
• If the vehicle is driven in heavy traffic or another situation where other vehi-cles are driven close by, it may take
time for the system to recognize the tire pressure warning valve and trans-mitters of your vehicle over those of
other vehicles. • If a wheel with a tire pressure warning valve and transmitter installed is
inside or near the vehicle, registration of the ID codes for the installed wheels may not be possible.
