Regulations on the use of snow chains● Regulations regarding the use of tire chains vary according to loca-
tion and type of road. Always check local regu lations before install-
ing chains.
● Install the chains on the rear tires.
● Retighten the chains after drivi ng 1/4 - 1/2 mile (0.5 - 1.0 km).
■Snow 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 only. Do not install tire chains on the
front tires.
● Install tire chains following the instructions provided in the accompanying
instructions.
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the size specified for your vehicle.
● 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.
● Snow tires should be installed on all wheels.
● 4WD models:
Do not mix tires of different makes, models, tread patterns or treadwear.

Driving with snow chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being
used or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden turns and braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
■Repairing or replacing snow tires
Request repairs of and obtain replac ement snow tires from Toyota deal-
ers or legitimate tire retailers.
This is because the removal and atta chment of snow tires affects the
operation of the tire pressure warning valves and transmitters.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function cor-
rectly when tire chains are fitted.

Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 666)
● Trailer tires should be inflated according to the trailer manufacturer’s rec-
ommendation.
● All trailer lights work to be legal.
● All lights work each time you connect them.
● The trailer ball is set up at the proper height for the coupler on the t\
railer.
● The vehicle remains level when a loaded or unloaded trailer is hitched.
Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, instal l rear view mirrors appropriate for
towing purposes.
● Depress TOW/HAUL button (if equipped)
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over 500
miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can s\
tart
towing. However, drive the vehicle at a speed of less than 50 mph (80 km/h)
when towing a trailer for another 500 miles (800 km). In addition, avoid full
throttle acceleration.

4-3. Do-it-yourself maintenance
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
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, Toyota recom-
mends that tire rotation is
carried out at the same inter-
val as tire inspection.
Do not fail to initialize the tire
pressure warning system
after tire rotation.
■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. 598)

Maintenance and care
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure 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
system must be initialized. Have tire pressure warning valve and trans-
mitter ID codes registered by your Toyota dealer. ( P. 544)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the fol-
lowing circumstances:
●When rotating the tires on vehicles differing with front and rear
tire inflation pressures.
● When changing the tire size.
When the tire pressure warning system is initialized, the current
tire inflation pressure is set as the pressure benchmark.
■ How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the engine switch off.
While the vehicle is moving, in itialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 666)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure
level.
Turn the engine switch to the ON position.

544 4-3. Do-it-yourself maintenance
Push and hold the tire pressure
warning reset switch until the
tire pressure warning light blinks
slowly 3 times.
Wait for several minutes with the engine switch on, and then
turn the engine switch to the ACC or LOCK position.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
■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 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.

Maintenance and care
■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
driving for about 20 minutes, the ti re 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 number given by divi ding the maximum load by 1.10 of
the replacement tire is greater than 1/2 of the Gross Axle Weight Ratings
(GAWR) of either the front axle or the rear axle, whichever is greater.
■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.
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. 673)
