CY20004
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 Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.Your Toyota is equipped with a limited−slip
center differential (transfer). If one wheel
begins to spin, the limited−slip center dif-
ferential (transfer) is designed to aid trac-
tion by automatically transmitting driving
force to the wheels on the other drive
axle. It transmits driving force to the front
wheels if a rear wheel spins, and to the
rear wheels if a front wheel spins.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
NOTICE
Use only a spare tire of the same
brand, size, construction and load ca-
pacity as the original tires on your
Toyota because damage to the limit-
ed−slip differential could possibly oc-
cur with another tire type.
CY20013
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 Toyota. It is used in registering
the ownership of your vehicle.

Your new vehicle carries theft preven-
tion labels which are approximately 47
mm (1.85 in.) by 12 mm (0.47 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.
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.

7. TUBELESS" or TUBE
TYPE" A tubeless tire does not
have a tube inside the tire and air
is directly filled in the tire. A tube
type tire has a tube inside the tire
and the tube maintains the air
pressure.
8. Load limit at maximum cold tire inflation pressure For details,
see Checking and replacing tires"
on page 443.
9. 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 467.
10.Summer tire or all season tireAn 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 368.

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 Toyota vehicles with in-
formation on uniform tire quality grad-
ing.
Your Toyota dealer will help answer
any questions you may have as you
read this information.
DOT quality gradesAll 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 A
Treadwear
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.
Uniform Tire Quality
Grading

356 Temperature A, B, CT he temper 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.
