QWhen to replace your vehicle’s tires
Tires should be replaced if:
OThe treadwear indicators are showing on a tire.
OYou have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating inter- nal damage.
OA tire goes flat repeatedly or cannot be properly repaired due to the size or location of a cut or other damage.
If you are not sure, consult with any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
QTire life
Any tire over 6 years old must be checked by a qualified technician even if
it has seldom or never been used or damage is not obvious.
QIf the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Rotate the tires in the order shown.
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
WARNING
QWhen 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 result-ing in death or serious injury.
ODo not mix tires of different makes, models or tread patterns.Also, do not mix tires of remarkably
different treadwear.
ODo not use tire sizes other than those recommended by Toyota.
ODo not mix differently constructed tires (radial, bias-belted or bias-ply tires).
ODo not mix summer, all season and snow tires.
ODo not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
OVehicles with compact spare tire: Do not tow if your vehicle has a compact spare tire installed.
OVehicles with emergency tire punc-ture repair kit: Do not tow anything
if a tire that has been repaired using the emergency tire puncture repair kit is installed. The load on the tire
may cause unexpected damage to the tire.
NOTICE
QDriving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.These conditions may cause losses in
tire inflation pressure, reducing the cushioning ability of the tires. In addi-tion, driving on rough roads may
cause damage to the tires them- selves, as well as the vehicle’s wheels and body.
QIf tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

QWhen 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.515, 564)
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.515, 522, 533)
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.
QHow 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.

QRoutine 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.
QTire inflation pressure
OIt 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.
OTire inflation pressure changes with
temperature. The displayed values
may also be different from the values
measured using a tire pressure
gauge.
QSituations in which the tire pres-
sure warning system may not oper-
ate properly
OIn 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.
OPerformance 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.
OWhen the vehicle is parked, the time

Maintenance and care
taken for the warning to start or go off
could be extended.
OWhen tire inflation pressure declines
rapidly for example when a tire has burst, the warning may not function.
QWarning 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.
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.
( P.470)
QWhen replacing the 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.
Installing tire pressure warn-
ing valves and transmitters
NOTICE
QRepairing or replacing tires, wheels, tire pressure warning
valves, transmitters and tire valve caps
OWhen 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.
OMake 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.
OWhen replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
QTo 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.465,
474)

4687-3. Do-it-yourself maintenance
QThe 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.470)
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.
QHow to initialize the tire pres-
sure warning system
1Park 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.
2Adjust the tire inflation pressure
to the specified cold tire inflation

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.
QWhen initializing
OInitialization is performed while driving
at a vehicle speed of approximately
40 km/h (25 mph) or more.
OMake 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.
OThe 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.
QThe initialization operation
OIf 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.
OIf 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.
OWhile 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.
QIf the tire pressure warning system
is not initialized properly
OIn 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.
OIf 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.
OIf 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.
OIn 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
