CAMRY_U (01999-06122)●
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 facility that generates strong
radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
Vehicles with a tire inflation pressure display function: If tire position
information is not correctly displayed due to the radio wave conditions,
the display may be corrected by changing the location of the vehicle as
the radio wave 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 example when a
tire has burst, the warning may not operate.
■Initialization procedure
●Make sure to perform the initialization procedure after adjusting the tire
inflation pressure.
Also, make sure the tires are cold before performing the initialization
procedure or adjusting the tire inflation pressure.
●If the engine switch is turned to the “LOCK” position (vehicles without a
smart key system) or off (vehicles with a smart key system) during ini-
tialization, it is not necessary to restart the initialization procedure from
the beginning as it will begin automatically when the engine switch is
turned back to the “ON” position (vehicles without a smart key system)
or IGNITION ON mode (vehicles with a smart key system).
●If initialization has accidentally been started when it is not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold and then perform the initialization procedure again.
●Vehicles with a tire inflation pressure display function: While the position
of each tire is being determined and the inflation pressures are not being
displayed on the multi-information display, if the inflation pressure of a
tire drops, the tire pressure warning light will come on.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accor-
dance with the conditions under which it was initialized. 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.

Maintenance and care
■If the tire pressure warning system is not initialized properly
Vehicles without a tire inflation pressure display function
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.
●If initialization is attempted and the tire pressure warning light does not
blink 3 times.
●If, when the vehicle has been driven for about 20 minutes after perform-
ing initialization, the tire pressure warning light blinks for approximately
1 minute and then illuminates.
Vehicles with a tire inflation pressure display function
●In the following situations, initialization 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 initialization.)
If initialization is not complete after driving approximately 30 minutes,
continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer to com-
plete initialization.
• If the vehicle is backed up while performing initialization, data col-
lected during initialization will be cleared and it will take longer than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other
vehicles are driven close by, it may take time for the system to recog-
nize the tire pressure warning valve and transmitters of your vehicle
over those of other vehicles.
If initialization is not complete after driving 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
completed properly and the system will not operate properly. Perform
the initialization procedure again.
• If, when attempting to start initialization, the tire pressure warning light
does not blink 3 times.
• If, when the vehicle has been driven for about 20 minutes after per-
forming initialization, the tire pressure warning light blinks for approxi-
mately 1 minute and then illuminates.
●If initialization cannot be completed after performing the above proce-
dure, contact your Toyota dealer.

When registering ID codes (vehicles with a tire inflation pressure dis-
play function)
●Before performing ID code registration, make sure that no wheels with
tire pressure warning valve and transmitters installed are near the vehi-
cle.
●Make sure to initialize the tire pressure warning system after registering
the ID codes. If the system is initialized before registering the ID codes,
the initialized values will be invalid.
●As the tires will be warm when registration is completed, make sure to
allow the tires to cool before performing initialization.
■Canceling ID code registration (vehicles with a tire inflation pressure
display function)
●To cancel ID code registration after it has been started, turn the engine
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 registration start procedure again and turn
the engine switch off before driving.
●If ID code registration has been canceled, the tire pressure warning light
will blink for approximately 1 minute when the engine switch is turned to
the “ON” position (vehicles without a smart key system) or IGNITION
ON mode (vehicles with a smart key system) and then illuminate. The
tire pressure warning system will be operational 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 cancelled correctly. To
cancel registration, perform the ID code registration start procedure
again and then turn the engine switch off before driving.

• If the vehicle is backed up while performing registration, data col-
lected during registration will be cleared, and it will take longer than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other
vehicles are driven close by, it may take time for the system to recog-
nize the tire pressure warning valve and transmitters 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.
If ID registration is not complete after driving for approximately 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
perform the ID code registration procedure again.
●In the following situations, ID code registration will not be started or was
not completed properly and the system will not operate properly. Per-
form the ID code registration procedure again.
• If, when attempting to start ID code registration, the tire pressure
warning light does not blink slowly 3 times.

Maintenance and care
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident
resulting in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
■When initializing the tire pressure warning system
Do not initialize the tire pressure warning system without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pres-
sure warning light may not come on even if the tire inflation pressure is
low, or it may come on when the tire inflation pressure is actually nor-
mal.
