Brake pad wear limit indicators
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Scion deal-
er as soon as possible. Expensive rotor
damage can result if the pads are not
replaced when necessary.
21B002
The vehicle identification number (VIN)
is the legal identifier for your vehicle.
This number is on the left top of the
instrument panel, and can be seen
through the windshield from outside.
This is the primary identification number
for your Scion. It is used in registering
the ownership of your vehicle.
21B003
The vehicle identification number (VIN) is
also on the Certification Label.
Your Scion’s identification—
—Vehicle identification
number

124
—Engine number
SU21007
The engine number is stamped on the
engine block as shown.
Theft prevention labels
Your new vehicle carries theft preven-
tion labels which are approximately 56
mm (2.20 in.) by 16 mm (0.63 in.).
The purpose of these labels is to reduce
the incidence of vehicle thefts by facilitat-
ing the tracing and recovery of parts from
stolen vehicles. The label is designed so
that once it is applied to a surface, any
attempt to remove it will result in destroy-
ing the integrity of the label. Transferring
these labels intact from one part to anoth-
er will be impossible.
NOTICE
You should not attempt to remove the
theft prevention labels as it may vio-
late certain state or federal laws.
Suspension and chassis
CAUTION
Do not modify the suspension/chassis
with lift kits, spacers, springs, etc. It
can cause dangerous handling charac-
teristics, resulting in loss of control.

symbols.
1. Tire size—For details, see “Tire
size” on page 127.
2. DOT and Tire Identification
Number (TIN)—For details, see
“DOT and Tire Identification Num-
ber (TIN)” on page 126.
3. 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.
4. Location of tread wear indica-
tors—For details, see “Checking
and replacing tires” on page 198.
5. Summer tire or all season tire—
An all season tire has “M+S” on
the sidewall. The tire not marked
with “M+S” is a summer tire. For
details, see “Types of tires” on
page 136.
6. 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.

126 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.
8. Uniform tire quality grad-
ing—For details, see “Uniform tire
quality grading” that follows.
9. Load limit at maximum cold tire
inflation pressure—For details,
see “Checking and replacing tires”
on page 198.
10. Maximum cold tire inflation
pressure—This means the pres-
sure to which a tire may be in-
flated. For details about recom-
mended cold tire inflation pressure,
see “Tires” on page 217.

—Uniform tire quality grading
This information has been prepared
in accordance with regulations issued
by the National Highway Traffic Safe-
ty Administration of the U.S. Depart-
ment of Transportation. It provides
the purchasers and/or prospective
purchasers of Scion vehicles with in-
formation on uniform tire quality grad-
ing.
Your Scion dealer will help answer
any questions you may have as you
read this information.
DOT quality grades—All passenger
vehicle tires must conform to Fed-
eral Safety Requirements in addi-
tion to these grades. Quality
grades can be found where appli-
cable on the tire sidewall between
tread shoulder and maximum sec-
tion width.
For example:
Treadwear 200 Traction AA
Temperature ATreadwear—The treadwear grade is
a comparative rating based on the
wear rate of the tire when tested un-
der controlled conditions on a speci-
fied government test course. For ex-
ample, a tire graded 150 would wear
one and a half (1−1/2) times as well
on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual
conditions of their use, however, and
may depart significantly from the
norm due to variations in driving hab-
its, service practices and differences
in road characteristics and climate.Traction AA, A, B, C—The traction
grades, from highest to lowest, are
AA, A, B, and C, and they represent
the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned
to this tire is based on braking
(straight ahead) traction tests and
does not include cornering (turning)
traction.

129 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.
