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.
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
■When 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.
●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.
●Vehicles with compact spare tire: Do not tow if your vehicle has a compact spare tire installed.
●Vehicles 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
■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.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

■When 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.575, 624)
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.575, 582, 593)
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.
■How 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.

■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 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.
●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
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.
