Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always chec k local regulations before installing
chains.
■ Tire chain installation
Observe the following precautions when installing and removing chains:
● Install and remove tire chains in a safe location.
● Install tire chains on the rear tires. Do not install tire chains on the front tires.
● Install tire chains on rear tires as tightly as possible. Retig hten chains after
driving 1/4  1/2 mile (0.5  1.0 km).
● Install tire chains following the instructions provided with th e tire chains.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in a loss of vehicle control and ca use death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
● 4WD models: Do not mix tires of different makes, models, tread patterns
or treadwear.
■ Driving with tire chains
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in the vehicle being unable to be d riven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tir e chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that v ehicle con-
trol is maintained.

NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealer s or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affect s the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not funct ion correctly
when tire chains are fitted.

Vehicle exterior
ItemsCheck points
Doors• Do the doors operate smoothly?
Engine hood• Does the engine hood lock system work prop-erly?
Fluid leaks• There should not be any signs of fluid leakageafter the vehicle has been parked.
Tires
• Is the tire inflati on pressure correct?
• The tires should not be damaged or exces- sively worn.
• Have the tires been rotated according to the maintenance schedule?
• The wheel nuts should not be loose.
Lights• Do all the lights come on?
Windshield wipers
• The wiper blades should not show any signs
of cracking, splitting, wear, contamination or
deformation.
• The wiper blades should clear the windshield without streaking or skipping.
WARNING
■If the engine is running
Turn the engine off and ensure that there is adequate ventilati on before per-
forming maintenance checks.

Maintenance and care
Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side o f 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 indicators ar e showing on a tire.
Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire
pressure warning system after
tire rotation.
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.

4967-3. Do-it-yourself maintenance
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 problems arise.
● The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
● If the tire pressure drops below a predetermined level, the dri ver is
warned by a screen display and a warning light.
◆Installing tire pressure warn ing valves and transmitters
When replacing tires or wheels, tire pressure warning valves an d
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized.
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating the tires.
● When the tire inflation pressure is changed such as when chang-
ing tire size. (When there are multiple specified pressures)
● After registeri ng the ID codes. ( P. 498)
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.

Maintenance and care
■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 t o
expose the fabric, and bulges indicating internal damage
●A 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.
■When replacing the tires and wheels
If the ID code of the tire press ure warning valve and transmitt er is not reg-
istered, the tire pressure warni ng system will not work properly. A f t e r d r i v -
ing for about 20 minutes, the tire pressure warning light blink s for
1 minute and stays on to indica te a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if it has seldom or never been u sed or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.
■Maximum load of tire
Check that the number given by dividing the maximum load by 1.1 0 of the
replacement tire is greater than 1/2 of the Gross Axle Weight R atings
(GAWR) of either the 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 mentioned on the
sidewall of the tire. ( P. 6 1 3 )

■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Si nce summer tires do not have th e same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy ro ads. 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 provide better traction in sno w and to
be adequate for driving in most winter conditions as well as fo r use
year-round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so, all
season tires fall short in acceleration and handling performanc e com-
pared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend us ing
snow tires. If you need snow tires, select tires of the same si ze, con-
struction and load capacity as t he originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construct ion. Do not install studded tires without
first checking local regulations for possible restrictions. Sno w tires
should be install ed on all wheels. ( P. 311)
■Initializing the tire pressure warning system
Initialize the system with the tire inflation pressure adjusted to the speci-
fied level.
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
