Maintenance and care
Rotate the tires in the order
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.

■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.
■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.
• 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 speci-
fied level.
• If wheel without the tire pressure
warning valve and transmitter is
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 display, airpo rt or other facil-
ity 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
correctly displayed due to the
radio wave conditions, the display
may be corrected by driving and
changing the radio wave condi-
tions.
●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 warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system w ill change in
accordance with the conditions
under which it was initialized. For
this reason, the system may give a
warning even if th e 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.

Drive the vehicle at approxi-
mately 25 mph (40 km/h) or
more for approximately 10 to 30
minutes until the inflation pres-
sure of each tire is displayed on
the multi-information display.
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, initialization can
be completed by driving for a
long time. However, if initializa-
tion 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.
■Initializing the tire pressure
warning system
Initialize the syst em with the tire
inflation pressure adjusted to the
specified level.
■Initialization procedure
●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
tire inflation pressure adjustment.
●If you have accidentally turned the
power switch off during initializa-
tion, it is not necessary to restart
the initialization ag ain as initializa-
tion will restart aut omatically when
the power switch has been turned
to ON for the next time.
●If you accidentally restart the ini-
tialization when ini tialization is not
necessary, adjust the tire inflation
pressure to the specified 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.
■When initializat
ion of the tire
pressure warning system has
failed
Initialization may take longer to
complete if the vehi cle is driven on
an unpaved road. When performing
initialization, drive on a paved road if
possible. Depending on the driving
environment and condition of the
tires, initialization will be completed
in approximately 10 to 30 minutes. If
initialization is not complete after
driving approximately 10 to 30 min-
utes, continue driving for a while.
If the inflation pressure of each tire
is not displayed after driving for
approximately 1 ho ur, perform the
following procedure.
●Park the vehicle in a safe place for
approximately 20 minutes. Then
drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes.
However, in the following situations,
the tire inflation pr essure will not be
recorded and the system will not
operate properly. Perform initializa-
tion 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
the beginning.
●When operating the tire pressure
warning reset switch, the tire pres-
sure warning light does not blink 3
times.
●After performing initialization, the
tire pressure warn ing light blinks
for 1 minute then stays on while
