Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID codes of the tire pressure warning valve and transmit ters are not
registered, the tire pressure warning system will not work properly. In this
case, after driving for about 20 minutes, the tire pressure warning light will
blink for approximately 1 minute and then illuminate to indicat e a system
malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if it has seldom or never been u sed or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.
■Low profile tires (vehicles with 18 or 19-inch wheels)
Generally, low profile tires will wear more rapidly and tire gr ip perfor-
mance will be reduced on snowy and /or icy roads when compared to
standard tires. Be sure to use snow tires on snowy and/or icy r oads and
drive carefully at a speed approp riate for road and weather conditions.
■Maximum load of tire
Check that the maximum load of t he replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axl e or the
rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the tire,
see the load limit at maximum cold tire
inflation pressure mentioned on the
sidewall of the tire. ( P. 5 9 3 )

Maintenance and care
●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 facilit y 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 ti re position
information is not correctly displayed due to the radio wave co nditions,
the display may be corrected by changing the location of the ve hicle 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 exampl e when a
tire has burst, the warning may not operate.
■Initialization procedure
●Make sure to perform the initialization procedure after adjusti ng the tire
inflation pressure.
Also, make sure the tires are cold before performing the initia lization
procedure or adjusting the tire inflation pressure.
●If the engine switch is turned t o the “LOCK” position (vehicles without a
smart key system) or off (vehicles with a smart key system) dur ing ini-
tialization, it is not necessary to restart the initialization procedure from
the beginning as it will begin aut omatically 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 pressu re to the specified level when the tires are
cold and then perform the ini tialization procedure again.
●Vehicles with a tire inflation p ressure 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 pr essure 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 pressu re warning system will change in accor-
dance with the conditions under which it was initialized. For t his reason,
the system may give a warning even if the tire pressure does no t reach a
low enough level, or if the pressure is higher than the pressur e that was
adjusted to when the sys tem was initialized.

If the tire pressure warning syst
em is not initialized properly
Vehicles without a tire inflat ion pressure display function
Initialization can be completed i n a few minutes. However, in the following
cases, the settings have not been record ed and the system will not oper-
ate properly. If repeated attempts to record tire inflation pre ssure settings
are unsuccessful, have the vehicl e inspected by your Toyota dealer.
●If initialization is attempted and the tire pressure warning li ght does not
blink 3 times.
●If, when the vehicle has been driven for about 20 minutes after perform-
ing initialization, the tire pre ssure warning light blinks for approximately
1 minute and t hen illuminates.
Vehicles with a tire inflation pressure display function
●In the following situations, init ialization may take longer than usual to be
completed or may not be possible. (Usually, the vehicle will ne ed to be
driven for approximately 10 to 30 minutes to complete initializ ation.)
If initialization is not complete after driving approximately 3 0 minutes,
continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longe r to com-
plete initialization.
• If the vehicle is backed up while performing initialization, d ata col-
lected during initialization will be cleared and it will take l onger than
normal to complete.
• If the vehicle is driven in heavy traffic or another situation where other
vehicles are driven close by, i t may take time for the system to recog-
nize the tire pressure warning valve and transmitters of your v ehicle
over those of other vehicles.
If initialization is not complete after driving for approximate ly 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
drive the vehicle again.
●In the following situ ations, initialization will not be started or was not
completed properly and the system will not operate properly. Pe rform
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 afte r per-
forming initializatio n, the tire pressure warning light blinks for approxi-
mately 1 minute and then illuminates.
●If initialization cannot be completed after performing the abov e proce-
dure, contact your Toyota dealer.

Maintenance and care
■When registering ID codes (vehicles with a tire inflation pressure dis-
play function)
●Before performing ID code registration, make sure that no wheel s 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 t he ID codes,
the initialized values will be invalid.
●As the tires will be war m when registration is completed, make sure to
allow the tires to cool befo re 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 r egistration start procedure aga in and turn
the engine switch of f before driving.
●If ID code registration has been canceled, the tire pressure wa rning light
will blink for approximately 1 mi nute when the engine switch is turned to
the “ON” position (vehicles witho ut a smart key system) or IGNITION
ON mode (vehicles with a smart ke y system) and then illuminate. The
tire pressure warning system will be operational when the tire pressure
warning ligh t turns off.
●If the warning light does not turn off even after several minut es have
elapsed, ID code registration may not have been cancelled corre ctly. To
cancel registration, perform the ID code registration start procedure
again and then turn the engine switch off before driving.

If ID codes are not registered properly (vehicles with a tire inflation
pressure display function)
●In the following situations, ID code registration may take long
er than
usual to be completed or may not be possible. (Usually, the veh icle will
need to be driven for approximately 10 to 30 minutes to complet e ID
code registration.)
If ID code registration is not complete after driving for appro ximately 30
minutes, continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longe r than
normal to complete registration.
• If the vehicle is backed up while performing registration, dat a 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, i t may take time for the system to recog-
nize the tire pressure warning valve and transmitters of your v ehicle
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 regi stration procedure again.
●In the following situations, ID c ode registration will not be started or was
not completed properly and the system will not operate properly. Per-
form the ID code registr ation procedure again.
• If, when attempting to start ID code registration, the tire pr essure
warning light does not blink slowly 3 times.
• If, when the vehicle has been driven for about 20 minutes afte r per-
forming ID code registration, the tire pressure warning light b links for
approximately 1 minute and then illuminates.
●If ID code registration cannot be completed after performing th e above
procedure, contact your Toyota dealer.
