there may be a problem with the
shift lock system. Have the vehi-
cle inspected by your Toyota
dealer immediately.
Vehicles with 17-inch or 18-
inch tires
Use the tire chains of correct
size and type.
Use SAE Class “S” type radial
tire chains, with the exception of
radial cable chains or V-bar type
chains.
Vehicles with 20-inch tires
Tire chains cannot be mounted.
Snow tires should be used
instead.
Regulations regarding the use
of tire chains vary depending on
location and type of road.
Always check local regulations
before installing chains.
■Tire chain installation
Observe the followi ng precautions
when installing and removing
chains:
●Install and remove tire chains in a
safe location.
●Install tire chains on the front tires
only. Do not install tire chains on
the rear tires.
●Install tire chains on front tires as
tightly as possible. Retighten
chains after drivi ng 1/4 - 1/2 mile
(0.5 - 1.0 km).
●Install tire chains following the
instructions provided with the tire
chains.

Maintenance and care
etc., molded into the sidewall of
each tire.
Replace the tires if the treadwear
indicators 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 internal damage.
●A tire goes flat repeatedly or can-
not 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.
■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 i s not obvious.
■Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2
of the Gross Axle Weight Ratings
(GAWR) of either t he front axle or
the rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum
cold tire inflation pressure men-
tioned on the sidewall of the tire.
(  P.530)
■Tire types
●Summer tires Summer tires are high-speed perfor-
mance tires best suited to highway
driving under dry conditions. Since
summer tires do not have the same
traction performance as snow tires,
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 install-
ing snow tires, be sure to replace all
four tires.
●All season tires
All season tires are designed to pro-
vide better traction in snow and to
be adequate for driving in most win-
ter conditions as well as for use
year-round. All season tires, how-
ever, do not have adequate traction
performance compared with snow
tires in heavy or loose snow. Also,
all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.
●Snow 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
originally installed tires. Since your
vehicle has radial tires as original
equipment, make sure your snow
tires also have radi al construction.
Do not install studded tires without
first checking local regulations for
possible restrictions. Snow tires
should be installed on all wheels.
(  P.343)
■If the tread on snow tires wears
down below 0.16 in. (4 mm)
The effectiveness of the tires as
snow tires is lost.

Maintenance and care
position information will not be
updated. If this accidentally occurs,
either turn the power switch to OFF
and then to ON, or initialize the sys-
tem after checking that the tire pres-
sure 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 inflation pressure before
serious problems arise.
The tire pressure warning sys-
tem of this vehicle adopts a 2-
type warning system
 When “Adjust Pressure” is
displayed (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 temperature.
(Ways of coping: P.472, 525)
 When “Immediately Check
tire when Safe” is displayed
(Emergency Warning)
The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low suddenly due to a
blowout. (Ways of coping: P.472,
481, 491) 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.

4406-3. Do-it-yourself maintenance
When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset
*.
Replacement wheels are avail-
able at your Toyota dealer.
*: Conventionally referred to as off- set.
Toyota does not recommend
using the following:
 Wheels of different sizes or
types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels
The wheels of your vehicle are
equipped with tire pressure warning
valves and transmitters that allow
the tire pressure warning system to
provide advance warning in the
event of a loss in tire inflation pres-
sure. Whenever wheels are
replaced, tire pressure warning
valves and transmitters must be
installed. ( P.427, 441)
Wheels
If a wheel is bent, cracked or
heavily corroded, it should
be replaced. Otherwise, the
tire may separate from the
wheel or cause a loss of
handling control.
Wheel selection
WARNING
■When replacing wheels
●Do not use wheels that are a dif-
ferent size from those recom-
mended in the Owner’s Manual,
as this may result in a loss of
handling control.
●Never 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 serious injury.
■When installing the wheel
nuts
Never use oil or grease on the
wheel bolts or wheel nuts. Oil and
grease may cause the wheel nuts
to be excessively tightened, lead-
ing to bolt or disc wheel damage.
In addition, the oil or grease can
cause the wheel nuts to loosen
and the wheel may fall off, caus-
ing an accident and resulting in
death or serious injury. Remove
any oil or grease from the wheel
bolts or wheel nuts.
■Use of defective wheels pro-
hibited
Do not use cracke d or deformed
wheels.
Doing so could cause the tire to
leak air during driving, possibly
causing an accident.
