142 2-5. Driving information
Regulations on the use of snow chainsl 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.
l Use SAE Class “S” type radial tire chains, with the exception of
radial cable chains or V-bar type chains.
• Install the chains on the front tires.
• Refer to the explanation that comes with the tire chains for
installation instructions.
l Retighten the chains after drivi ng 1/4 - 1/2 mile (0.5 - 1.0 km).
nSnow chain installation
Observe the following precautions when installing and removing chains.
lInstall and remove tire chains in a safe location.
l Install tire chains on the front tires only. Do not install tire chains on the
rear tires.
l Install the tire chains on front tires as tightly as possible.
l Install tire chains following the instructions provided in the accompanying
instructions.
l If wheel ornaments are used, they will be scratched by the chain band,
so remove the ornaments before putting on the chains. ( →P. 305)
nWhen driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
n When parking the vehicle
Park the vehicle and move the shift lever to P (automatic trans-
mission) or to 1 or R (manual transmission) without setting the
parking brake. The parking brak e may freeze up, preventing it
from being released.

When driving
CAUTION
n
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.
lUse tires of the size specified for your vehicle.
l Maintain the recommended level of air pressure.
l Do not drive in excess of 75 mph (120 km/h) regardless of the type of
snow tires being used.
l Snow tires should be installed on all wheels.
n 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.
lDo not drive in excess of the speed limit specified for the tire chains being
used or 30 mph (50 km/h), whichever is lower.
l Avoid driving on bumpy road surfaces or over potholes.
l Avoid sudden turns and braking.
l Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
nRepairing or replacing snow tires
Request repairs of and obtain replacement snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
n Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

242 4-3. Do-it-yourself maintenance
nMaximum load of tire
Check that the maximum load of the replaced 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.
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 Ratings (GAWR) , see the Certification Label. (→P.
246, 338).
nTire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Sinc e 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. 141)

4-3. Do-it-yourself maintenance
Wheels
nWhen replacing wheels
The wheels of your Toyota are equipped with sensors that allow the tire
pressure warning system sensors to provide advanced warning in the
event of a loss in tire inflation pressure. Whenever wheels are replaced,
the tire pressure warning valve and transmitter must be switched over
from the old wheels. (→P. 241)
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
handling control.
n Wheel selection
When replacing wheels, care should 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:
lWheels of different sizes or types
l Used wheels
l Bent wheels that have been straightened
n Aluminum wheel precautions (if equipped)
lUse 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 Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

When trouble arises

5-2. Steps to take in an emergency
nIf the tire pressure warning system is inoperative
The tire pressure warning system will become inoperative in the follow-
ing conditions:
(When the condition be
comes normal, the system will work properly.)
lIf tires not equipped with tire pressure warning valves and transmit-
ters are used.
lIf the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
lIf the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
The tire pressure warning system may become inoperative in the follow-
ing conditions:
(When the condition be comes normal, the system will work properly.)
lIf electronic devices or facilities using similar radio wave frequencies
are nearby.
lIf a radio set at similar frequencies is in use in the vehicle.
lIf a window tint that affects the radio wave signals is installed.
lIf there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
lIf non-genuine Toyota wheels are used. (Even if you use Toyota
wheels, the tire pressu re warning system may not work properly with
some types of tires.)
lIf tire chains are used.
nIf the tire pressure warning light comes on after blinking for 1
minute frequently
If the tire pressure warning light comes on after blinking for 1 minute fre-
quently when the engine switch is turned to the ON position, have it
checked by your Toyota dealer.
n After changing the engine oil (except Canada)
Make sure to reset the oil maintenance data. ( →P. 230)
n Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
