Maintenance and care
Tires
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.
■Checking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear
indicators is shown by the
“TWI” or “ ” marks, etc.,
molded on the sidewall of
each tire.
Check spare tire condition
and inflation pressure if not
rotated.
■Tire rotation
Vehicles without compact spare tire
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, Toyota rec-
ommends that tire rotation is
carried out at the same inter-
val as tire inspection.

ommends that tire rotation is

val as tire inspection.
■The tire pressure warning system
Your Toyota is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low
tire inflation pressure before serious problems arise.
( P. 494, 500)
Vehicles with compact spare tire : The compact spare tire is not
equipped with the tire pressure warning valve and transmitters.

■When to replace your vehicle's tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal 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 your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure warning system will not work properly. After
about 20 minutes, the tire pressure warning light comes on after blinking
for 1 minute to indicate a system malfunction.
■Tire 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.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Maximum load of tire
Check that the maximum load of the re placed tire is greater than 1/2 of
the Gross Axle Weight Rating (GAWR) of either the front axle or the rear
axle, whichever is greater.
As for the maximum load of the tire, see the load limit at maximum cold
tire inflation pressure mentioned on the sidewall of the tire, and as for the
Gross Axle Weight Rating (GAWR), see the Certification Label.

Maintenance and care
■Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3Snow tires For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( P. 230)
■Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make su re to check tire inflation pressure as part of
your routine of daily vehicle checks.

NOTICE
■Repairing 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 Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled cor-
rectly.
■To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.
■Driving 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.
■If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
