Tires and loading on your Scion
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see page 199 and pages
135 through 136.
Scrapping of your Scion
The SRS airbag and seat belt pretensioner devices in
your Scion contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as a fire. Be sure
to have the systems of the SRS airbag and seat belt
pretensioner removed and disposed of by a qualified
service shop or by your Scion dealer before you dis-
pose of your vehicle.

7. “TUBELESS” or “TUBE TYPE”
—A tubeless tire does not have a
tube inside the tire and air is direct-
ly filled in the tire. A tube type tire
has a tube inside the tire and the
tube maintains the air pressure.

symbols.
1. “TEMPORARY USE ONLY”— A
compact spare tire is identified by
the phrase “TEMPORARY USE
ONLY” molded into its sidewall.
This tire is designed for temporary
emergency use only. For details,
see “Compact spare tire” on page
156.
2. Tire size— For details, see “Tire
size” on page 129.
3. DOT and Tire Identification Number (TIN)— For details, see
“DOT and Tire Identification Num-
ber (TIN)” on page 128.

7. Tire ply composition and materi- als— Plies mean a layer of rubber −
coated parallel cords. Cords mean
the strands forming the plies in the
tire.
8. “TUBELESS” or “TUBE TYPE” —A tubeless tire does not have a
tube inside the tire and air is direct-
ly filled in the tire. A tube type tire
has a tube inside the tire and the
tube maintains the air pressure.
9. Radial tires or biasply tires— A
radial tire has “RADIAL” on the
sidewall. A tire not marked with
“RADIAL” is a bias −ply tir e.

Temperature A, B, C—
T he tem per a-
ture grades are A (the highest), B,
and C, representing the tire’s resis-
tance to the generation of heat and
its ability to dissipate heat when
tested under controlled conditions on
a specified indoor laboratory test
wheel. Sustained high temperature
can cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B
and A represent higher levels of per-
formance on the laboratory test wheel
than the minimum required by law. Warning: The temperature grades for
this tire are established for a tire that
is properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading, either sep-
arately or in combination, can cause
heat buildup and possible tire failure.

Scion does not recommend towing a
trailer with your vehicle. Scion also
does not recommend the installation of
a tow hitch or the use of a tow hitch
carrier for a wheelchair, scooter, bi-
cycle, etc. Your Scion is not designed
for trailer towing or for the use of tow
hitch mounted carriers.Improving fuel economy is easy–just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure.
Underinflation causes
tire wear and wastes fuel. See page
199 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Avoid lengthy warmup idling. Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
Keep the automatic transmission
overdrive turned on when engine
braking is not required. Driving with
the overdrive off will reduce the fuel
economy. (For details, see “Automatic
transmission” on page 87.)
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.
Avoid engine lugging or overrev-
ving. Use a gear position suitable for
the road on which you are travelling.
Avoid continuous speeding up and
slowing down. Stop−and− go driving
wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econo-
my.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
