Maintenance and care
■The tire pressure warning sys-
tem must be init ialized in the
following circumstances:
 When rotating front and rear tires
which have different tire inflation
pressures.
 When changing the tire size.
 When the tire inflation pressure
is changed such as when chang-
ing traveling speed or load
weight.
 When changing between two
registered wheel sets.
When the tire pressure warning
system is initialized, the current tire
inflation pressure is set as the
benchmark pressure.
■How to initialize the tire pres-
sure warning system
1 Park the vehicle in a safe place
and turn the power switch off,
wait for approximately 15 min-
utes or more, and then perform
the procedure.
2 Adjust the tire inflation pressure
to the specified cold tire inflation
pressure level. ( P.490)
Make sure to adjust the tire pressure to the specified cold tire inflation pressure
level. The tire pressure warning system will operate based on this pressure level.
3 Turn the power switch to ON.
Initialization cannot be performed while the vehicle is moving.

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

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.

6-3. Do-it-yourself maintenance
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.

When the 12-volt battery charge becomes insufficient or the voltage tem-
porarily drops, the electric power steer- ing system warning light may come on and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: P.448, 459
If none of the tires are punctured: Turn the power switch off then turn it to
ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks
for approximately 1 minute then stays on
There may be a malfunction in the tire
pressure warning system. Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immedi- ately.
If the tire pressure warning light
comes on
1 After the temperature of the tires has lowered sufficiently, check the infla-tion pressure of each tire and adjust
them to the specified level.
2 If the warning light does not turn off even after several minutes have elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization. ( P.395)
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres- sure changes caused by temperature. In this case, adjusting the tire inflation
pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare
tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and trans- mitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire has been replaced with the spare tire. Replace the spare tire with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few min-utes.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare tire is low. If a tire goes flat, the
tire pressure warning light will not turn off even though the flat tire has been replaced with the spare tire. Replace the
spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressure warning light will go off after a
few minutes.
