■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
● Use a child restraint system appropriate for the child, until the child
becomes large enough to properly w ear the vehicle’s seat belt. (P. 87)
● When the child becomes large enough to properly wear the vehicle’s
seat belt, follow the instructions on P. 47 regarding seat belt usage.
■ Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate
for the first collision, but will not activate for the second or subsequent colli-
sions.
■ Seat belt extender
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your Scion
dealer free of charge.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
● To ensure proper operation of th e climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
● Remove any ice that has accumu lated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.

Selecting tire chainsUse the correct tire chain size when mounting the tire chains. Chain
size is regulated for each size.
Side chain
(0.12 in. [3 mm] in diameter)
Cross chain
(0.16 in. [4 mm] in diameter)
■When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to the road conditions.
■ When parking the vehicle (in the winter time or in the cold
latitudes)
Park the vehicle and move the shift lever to P (automatic trans-
mission) or 1 or R (manual transmission) without setting the
parking brake. The parking brak e may freeze up, preventing it
from being released. If necessary , block the wheels to prevent
inadvertent sliding or creeping.

CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the size specified.
● 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.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure 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, as use of chains may adversely affect
vehicle handling.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

Maintenance and care

■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, 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 Scion dealer.
■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 tire pressure warning light blinks for
1 minute and stay on to indicate a system malfunction.
■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 is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make su re to check tire inflation pressure as part of
your routine of daily vehicle checks.
■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.
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. 343)

■Tire types
●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.
●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.
●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 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 restrictions. Snow tires
should be installed on all wheels. ( P. 161)
■Initializing the tire pressure warning system
Initialize the system with the tire infl ation pressure adjusted to the speci-
fied level.
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.

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
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and inset
*.
Replacement wheels are available at your Scion dealer.
*: Conventionally referred to as “offset”.
Scion 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 pressure.
Whenever wheels are replaced, tire pressure warning valves and trans-
mitters must be installed. (
P. 237)
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may resu lt 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 seri-
ous 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,
leading 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, causing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
●Be sure to install the wheel nuts with
the tapered end faci ng inward. Install-
ing the nuts with the tapered end fac-
ing outward can cause wheel to
break and eventually cause a wheel
to come off while driving, which could
lead to an accident resulting in death
or serious injury.Tapered
