●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 not to able detect.
■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.397)
■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
NOTICE
■Repairing or replacing tires,
wheels, tire pressure warning valves, transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as
the tire pressure warning valves and transmitters may be damaged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves, corrode the valve, and cause sticking and
air leaks.
●When replacing tire valve caps, do
not use tire valve caps other than those specified. The cap may become stuck.

formed.
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.398)
■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 more than 15
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

stopped for a long time at traffic lights, etc. ( P.398)
8Initializing the tire pressure
warning system. ( P.395)
■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 again to select “Identifying Each Wheel & Position”. ( P.397)
●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.
If ID registration is not complete after
driving for approximately 1 hour, park
the vehicle in a safe place for approxi-
mately 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 sys-
tem will not operate properly. Perform 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.
• If, when the vehicle has been driven for about 10 minutes after performing ID code registration, the tire pressure
warning light blinks for approximately 1 minute and then illuminates.

Maintenance and care
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced safety
●Damage to the drivetrain
●Reduced tire life due to wear
●Reduced fuel economy
●Reduced driving comfort and poor
handling
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Instructions for checking tire infla-tion pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.If your vehicle has been parked for at least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold tire inflation pressure reading.
●Always use a tire pressure gauge.It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the tire inflation pres-
sure to be higher after driving as heat is generated in the tire. Do not reduce
tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is balanced.
WARNING
■Proper inflation is critical to save
tire performance
Keep your tires properly inflated. If the tires are not properly inflated,
the following conditions may occur which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire dam-age
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges on the road, etc.)
NOTICE
■When inspecting and adjusting
tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and cause an air leak, resulting in
decreased tire inflation pressure.

When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire
inflation pressure. Whenever wheels are replaced, the tire pressure warning valves and transmitters must be
installed. ( P.394)
■When removing the wheel orna-
ment (vehicles with an emergency tire puncture repair kit)
Remove the wheel ornament using the
wheel cap clip*.*: The wheel cap clip is installed in the
glove box. ( P.353)
Wheels
If a wheel is bent, cracked or
heavily corroded, it should be
replaced. Otherwise, the tire
may separate from the wheel
or cause a loss of handling
control.
Wheel selection
WARNING
■When replacing wheels
●Do not use wheels that are a differ- ent size from those recommended in the Owner’s Manual, as this may
result in a loss of handling control.
●Never use an inner tube in a leak-
ing wheel which is designed for a tubeless tire.Doing so may result in an accident,
causing death or serious injury.
■When installing the wheel nuts
●Be sure to install the wheel nuts with the tapered ends facing inward ( P.464). Installing the nuts with
the tapered ends facing outward can cause the wheel to break and eventually cause the wheel to come
off while driving, which could lead to an accident resulting in death or serious injury.

Maintenance and care
Use only Toyota wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
 When rotating, repairing or
changing your tires, check that
the wheel nuts are still tight after
driving 1600 km (1000 miles).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine balance
weights or equivalent and a plas-
tic or rubber hammer when bal-
ancing your wheels.
WARNING
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight-ened, leading to bolt or disc wheel
damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall off,
causing an accident and resulting in death or serious injury. Remove any oil or grease from the wheel bolts or
wheel nuts.
■Use of defective wheels prohib-
ited
Do not use cracked or deformed wheels. Doing so could cause the tire
to leak air during driving, possibly causing an accident.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement
may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer. In addition, make sure to
purchase your tire pressure warn- ing valves and transmitters at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
●Ensure that only genuine Toyota wheels are used on your vehicle.Tire pressure warning valves and
transmitters may not work properly with non-genuine wheels.
