Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
When rotating front and rear tires which
have different tire inflation pressures,
do not fail to initialize the tire pressure
warning system after tire rotation.
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)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is an unknown level of low tire
pressure with the appearance of the tire
due to natural air leakage as well as the
pressure lowering due to changes in
the pressure according to the outside
temperature. (Ways of coping: P.443,
490)
 When “Immediately Check tire
when Safe” is displayed (Emer-
gency Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is a known level of low tire pres-
sure with the appearance of the tire due
to pressure suddenly lowering. (Ways
of coping: P.448, 459)
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 9-inch display
multimedia system or multi-infor-
mation display.
9-inch display multimedia system
1 Press the “HOME” button.
2 Select “Vehicle” on the “Home”
screen.
3 If a screen other than “Tyre
pressure” is displayed, select

●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.
●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 not to able detect.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning
system will change in accordance with driving conditions. 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.
Have tire pressure warning valves
and transmitter ID codes regis-
tered any authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer. ( P.397)
■Replacing 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
■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, corrode the valve, and cause sticking and
air leaks.
●When replacing tire valve caps, do
not use tire valve caps other than those specified. The cap may become stuck.
