Maintenance and care
shown. Front
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is c arried out at the
same interval as tire inspection.
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
 The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
( P.105) 
If the tire pressure drops
below a predetermined level,
the driver is warned by a
screen display and a warning
light. ( P.447)
■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 o f daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the power switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after infl ation 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
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are used.
• If a tire has been replaced with a tire that is not an OE (Original
Equipment) tire.
• If a tire has been replaced with a tire that is not of the specified size.
• If tire chains, etc. are installed.
• 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
much higher than the specified
level.
• If wheels not equipped with tire
pressure warning valves and
transmitter 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.
• When driving near a TV tower, electric power plant, gas station,
radio station, large display, airport
or other facility that generates
strong radio waves or electrical
noise
• When carrying a portable radio, cellular 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
corrected by changing the location
of the vehicle 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 example when a tire has burst, the warning
may not operate.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system w ill change in
accordance the conditions under
which it was initia lized. For this rea-
son, 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 sys-
tem was initialized.
■Tire pressure warning system
certification
 P.553
When replacing the tires or
wheels, the tire pressure warn-
ing valves and transmitters must
be installed to the wheels which
will be installed to the vehicle.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer and the tire
pressure warning system must
be initialized. ( P.409)
■Replacing tires and wheels
If the ID codes of the tire pressure
warning valves and transmitters are
not registered, the tire pressure
warning system will not work prop-
erly. In this case, after driving for
about 10 minutes, the tire pressure
warning light will blink for approxi-
mately 1 minute and then illuminate
to indicate a system malfunction.

utes.
When initialization is complete, the
inflation pressure of each tire will be
displayed on the multi-information
display.
Even if the vehicle is not driven at
approximately 25 mph (40 km/h) or
more, initializat ion can be com-
pleted by driving for a long time.
However, if initia lization does not
complete after driving for 1 hour or
more, park the vehicle in a safe
place for approximately 20 minutes
and then drive th e vehicle again.
■When initializing
●Initialization is performed while
driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Make sure to carry out initializa-
tion after adjusting the tire inflation
pressure. Also, make sure the
tires are cold before carrying out
initialization or tir e inflation pres-
sure adjustment.
●The tire pressure warning system
can be initialized by yourself, but
depending on the driving condi-
tions and driving environment, ini-
tialization may take some time to complete.
■The initialization operation
●If you have accidentally turned the
power switch off during initializa-
tion, it is not necessary to manu-
ally restart the initialization again,
as initialization will restart auto-
matically the next time the power
switch is turned to ON.
●If you accidentally perform initial-
ization when initia
lization is not
necessary, adjust the tire inflation
pressure to the s pecified level
when the tires are cold, and con-
duct initialization again.
●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 pressure of a tire
drops, the tire pressure warning
light will come on.
■If the tire pressure warning sys-
tem is not initia lized properly
●In the following situations, initial-
ization may take longer than usual
to be completed or may not be
possible. Normally, initialization
completes within approximately
30 minutes.
• Vehicle is not dr iven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehi-
cles and system cannot recog-
nize tire pressure warning valve
and transmitters o f 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
approximately 20 minutes and then
drive the vehicle again.
●If the vehicle is reversed during
initialization, the data up to that
point is reset, so p erform the ini-
tialization procedure again from
