molded into the sidewall of each tire.
Replace the tires if the treadwear indi-
cators are showing on a tire.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating inter- nal damage
●A 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.
■Tire 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.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
■Checking the tire valves
When replacing the tires, check the tire
valves for deformation, cracks, and other damage.
Rotate the tires in the order shown.
WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents. Failure to do so may cause damage to parts of the drivetrain as well as
dangerous handling characteristics, which may lead to an accident result-ing in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.Also, do not mix tires of remarkably
different treadwear.
●Do not use tire sizes other than
those recommended by Toyota.
●Do not mix differently constructed
tires (radial, bias-belted or bias-ply tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.Do not use tires if you do not know
how they were used previously.
NOTICE
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
■Driving 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.
Tire rotation

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
“Tyre pressure”.

■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 tires not equipped with 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.
●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.
