Do not fail to initialize the tire pressure
warning system after tire rotation.
Front
■When rotating the tires
Make sure that the power switch is OFF.
If the tires are rotated while the power
switch is in ON, the tire position informa-
tion will not be updated.
If this accidentally occurs, either turn the
power switch to OFF and then to ON, or
initialize the system after checking that
the tire pressure is properly adjusted.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
The tire pressure warning system
of this vehicle adopts a 2-type
warning system
When “Adjust Pressure” is dis-
played (Normal Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire inflation pressure becomes low due to
natural air leakage or outside tempera-
ture. (Ways of coping: P.575, 624)
When “Immediately Check tire
when Safe” is displayed (Emer-
gency Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire
inflation pressure becomes low sud-
denly due to a blowout. (Ways of cop-
ing: P.575, 582, 593)
However, the system may not be able
to detect sudden tire ruptures (bursting,
etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa-
tion display.
The unit can be changed.
■How to change the unit
1Park the vehicle in a safe place
and turn the power switch off.
Changing the unit cannot be performed
while the vehicle is moving.
2Turn the power switch to ON.

■Routine tire inflation pressure
checks
The tire pressure warning system does
not replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display
the tire inflation pressure after the
power switch is turned to ON. It may
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 wheels without 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
If tire position information is not cor-
rectly displayed due to the radio wave
conditions, the display may be cor-
rected by driving and changing the
radio wave conditions.
●When the vehicle is parked, the time

Maintenance and care
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
the conditions under which it was initial-
ized. 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.

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.
■The tire pressure warning sys-
tem must be initialized in the
following circumstances:
 When rotating the tires.
 When changing the tire.
 After registering the ID codes.
( P.525)
 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 stop the hybrid system for
20 minutes or more.
Initialization cannot be performed while the vehicle is moving.
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 and the
tire pressure warning valves could be bound.
●When replacing tire valve caps, do not use tire valve caps other than those specified.
The cap may become stuck.
■To avoid damage to the tire pres- sure warning valves and trans-mitters (vehicles without spare
tire)
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is used, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer or other qualified ser-vice shop as soon as possible. Make
sure to replace the tire pressure warn- ing valve and transmitter when repair-ing or replacing the tire. ( P.511,

information display. Also, “--” is dis-
played for inflation pressure of each tire
on the multi-information display while
the tire pressure warning system deter-
mines the position.
8Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25mph) or
more for approximately 10 to 30
minutes.
When initialization is complete, the
inflation pressure of each tire will be
displayed on the multi-information dis-
play.
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 approximately 20
minutes and then drive the vehicle
again.
■When initializing
●Initialization is performed while driving
at a vehicle speed of approximately
40 km/h (25 mph) or more.
●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.
●The tire pressure warning system can
be initialized by yourself, but depend-
ing on the driving conditions and driv-
ing environment, initialization may
take some time to complete.
■The initialization operation
●If you have accidentally turned the
power switch to OFF during initializa-
tion, it is not necessary to restart the
initialization again as initialization will
restart automatically when the power
switch has been turned to ON for the
next time.

Maintenance and care
●If you accidentally perform initializa-
tion 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. Nor-mally, initialization completes within
approximately 30 minutes. • Vehicle is not driven at approximately 40 km/h (25 mph) or more
• Vehicle is driven on unpaved roads • Vehicle is driven near other vehicles and system cannot recognize tire
pressure warning valve and transmit- ters of your vehicle over those of other vehicles.
• 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 does not complete after
driving for 1 hour or more, park the vehicle in a safe place for approxi-mately 20 minutes and then drive the
vehicle again.
●If the vehicle is reversed during initial-
ization, the data up to that point is reset, so perform the initialization pro-cedure again from the beginning.
●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, con-
tact any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
Every tire pressure warning valve
and transmitter has a unique ID
code. When replacing a tire pres-
sure warning valve and transmitter,
it is necessary to register the ID
code.
When registering the ID codes, per-
form the following procedure.
1 Park the vehicle in a safe place,
wait for approximately 20 min-
utes, and then start the hybrid
system.
WARNING
■When initializing the tire pres-
sure warning system
Do not initialize tire inflation pressure without first adjusting the tire inflation
pressure to the specified level. Other- wise, the tire pressure warning light may not come on even if the tire infla-
tion pressure is low, or it may come on when the tire inflation pressure is actually normal.

Maintenance and care
complete when the tire pressure warn-
ing light turns off and the inflation pres-
sure of each tire is displayed on the
multi-information display.
■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres-
sure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
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
Tire inflation pressure
Make sure to maintain the
proper tire inflation pressure.
Tire inflation pressure should
be checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. (P.624)

5307-3. Do-it-yourself maintenance
should be placed so that the vehicle is
balanced.
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, tire pressure warning valves and transmitters must be installed.
( P.511, 531)
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 in 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.
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.
