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.
■ 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.

NOTICE
■Repairing or replacing snow tires
Request repairs of and obtain replacement snow tires from Scion 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.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly\
when tire chains are fitted.

CAUTION
■Using the jack
Improper use of the jack may lead to death or serious injuries due to the
vehicle suddenly falling off the jack.
●Do not use the jack for any purpose ot her than replacing tires or install-
ing and removing tire chains.
●Do not use it on other vehicles, an d do not use other jacks for replac-
ing tires on this vehicle.
●Always check that the jack is securely set to the jack point.
●Do not put any part of your body under the vehicle supported by a jack.
●Do not start or run the engine while your vehicle is supported by the
jack.
●Do not raise the vehicle while someone is in it.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a hei ght greater than that required to
replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that no one
working on or near the vehicle will be injured.
■Replacing a tire
Observe the following precautions to reduce the risk of death or serious
injury.
●Have the wheel nuts tightened with a torque wrench to 76 ft·lbf (103
N·m, 10.5 kgf·m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the nuts to loosen and
the wheel may fall off, which could lead to an accident causing death
or serious injury.
●Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.

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.
■Tire rotation
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, Scion recom-
mends that tire rotation is
carried out at the same inter-
val as tire inspection.
■The tire pressure warning system
Your Scion 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. 280)

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 the tire pressure warning
system must be initialized. Have tire pressure warning valve and trans-
mitter ID codes registered by your Scion dealer.
Initializing the tire pressure warning system
The tire pressure warning system mu st be initialized when rotating
the tires on vehicles differing with front and rear tire inflation pres-
sures.
When the tire pressure warning syst em 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.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 327)
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.
