such as excessive wear on one
side of the tread.
Check the spare tire condition and
pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is
shown by a “TWI” or “ ” mark, etc.,
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.

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.

4807-3. Do-it-yourself maintenance
Rotate the tires in the order shown.
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 afte r tire rotation.
Rotate the tires in the order shown.

●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 a compact spare tire:
Do not tow if your vehicle has a compact spare tire installed.
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.

Vehicles with a full-size spare tire
Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
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.
If the tire pressure drops below a
predetermined level, the driver is
warned by a warning light.
( P.515)
■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 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 warning may not function.
■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
