Treadwear indicator
Worn tread
The location of treadwear
indicators is shown by the

molded on the sidewall of
ea
ch tire.
Check spare tire condition
an
d inflation pressure if not
rotated.
n Tire rotation
Rotate the tires in the order
show

To equalize tire wear and
extend tire life, Toyota recom -
mends that tire rotation is
ca
rried out at the same inter -

Maintenance and care
Ti
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, ti re pressu
re warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis -
tered in the tire pressure warning computer and tire pressure warning
sy
stem must be initialized. Have tire pressure warning valve and trans -
mitter ID codes registered by your Toyota dealer.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a ti re pressure warning valve and
transmitter, it is necessary to register the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
nWhen to replace your vehicle's tires
Tires should be replaced if:
lYou have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
lA tire goes flat repeatedly or c annot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
nReplacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure w

arning system will not work properly. After
driving for about 20 minutes, the ti re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
nTire life
Any tire over 6 years old must be checked by a qualified technician even
if

they have seldom or never been used or damage is not obvious.

Maintenance and care
NOTICE
nRepairing or replacing tires, wheels and tire pressure warning
valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your To
yota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
nTo avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.
nDriving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition driving on rough roads may
cause damage to the tires themselves, as well as the vehicle's wheels
and body.
nIf tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

4-3. Do-it-yourself maintenance
Wheels
nWhen replacing wheels
The wheels of your Toyota are equipped with tire pressure warning
valves an
d transmitters that allow the tire pressure warning system to
provide advanced warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, the tire pressure warning valves and
transmitters must be installed. ( →P. 2 5 9 )
If a wheel is bent, cracked or heavily corroded, it should be
replaced.

Otherwise, the tire may separate from the wheel or cause loss of
ha
ndling control.
nWheel selection
When replacing wheels, care shou ld
be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and offset.
Replacement wheels are available at your Toyota dealer.
Toyota does not recommend using:
l Whee
ls of different sizes or types
lUs
ed wheels
lBe
nt wheels that have been straightened
n Aluminum wheel precau
tions (if equipped)
l Use only
Toyota wheel nuts and wrench designed for use with
your aluminum wheels.
l When
rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
l Be
careful not to damage the aluminum wheels when using
tire chains.
l Use only T
oyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

Maintenance and care
CAUTION
nWhen replacing wheels
lDo not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may re
sult in loss of handling control.
lNever use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
NOTICE
nReplacing tire pressure warning valves and transmitters
lBecause tire repair or replacement may affect the tire pressure warn-
ing valves and transmitte rs, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
lEnsure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.
