Camper information
If you believe that your vehicle
has a defect which could cause a
crash or could cause injury or
death, you should immediately in-
form the National Highway Traffic
SafetyAdministration (NHTSA) in
addition to notifying Toyota Motor
Sales, U.S.A., Inc. (Toll-free:
1-800-331-4331).
If NHTSA receives similar comp-
laints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of ve-
hicles, it may order a recall and
remedy campaign. However,
NHTSA cannot become involved
in individual problems between
you, your dealer, or Toyota Motor
Sales, U.S.A., Inc.. To contact NHTSA, you may ei-
ther call the Auto Safety Hotline
toll-free at 1-800-424-9393 (or
366-0123 in Washington.D.C.
area) or write to: NHTSA. U.S.
Department of Transportation. Wa-
shington.D.C. 20590. You can also
obtain other information about mo-
tor vehicle safety from the Hotline.

This information has been prepared in ac-
cordance with regulations issued by the
National Highway Traffic Safety Adminis-
tration of the U.S. Department of Trans-
portation. It provides the purchasers and/
or prospective purchasers of Toyota
vehicles with information on uniform tire
quality grading.
Your Toyota dealer will help answer any
questions you may have as you read this
information.
DOT quality grades—All passenger ve-
hicle tires must conform to Federal
Safety Requirements in addition to
these grades. These quality grades are
molded on the sidewall.
Treadwear—
The treadwear grade is a
comparative rating based on the wear rate
of the tire when tested under controlled
conditions on a specified government test
course. For example, 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 condi-
tions of their use, however, and may de-
part significantly from the norm due to
variations in driving habits, service prac-
tices and differences in road characteris-
tics and climate. Traction A, B, C—
The traction grades,
from highest to lowest, are A, B, and C,
and they represent the tire’s ability to stop
on wet pavement as measured under con-
trolled conditions on specified government
test surfaces of asphalt and concrete. A
tire marked C may have poor traction per-
formance.Warning: The traction grade as-
signed to this tire is based on braking
(straight ahead) traction tests and does
not include cornering (turning) traction.
Temperature A, B, C— The temperature
grades are A (the highest), B, and C,
representing the tire’s resistance to the
generation of heat and its ability to dissi-
pate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature
can cause the material of the tire to de-
generate and reduce tire life, and exces-
sive temperature can lead to sudden tire
failure. The grade C corresponds to a lev-
el 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 perfor-
mance 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 prop-
erly inflated and not overloaded. Exces-
sive speed, underinflation, or excessive
loading, either separately or in combina-
tion, can cause heat buildup and possible
tire failure.

Camper information—
This information has been prepared in ac-
cordance with regulation issued by the Na-
tional Highway Traffic Safety Administra-
tion of the U.S. Department of
Transportation. It provides the purchasers
and/or prospective purchasers of Toyota
vehicles with information on truck-camper
loading. Your Toyota dealer will help an-
swer any questions you may have as you
read this information.
—Center of gravity location

T100(U)
212
The figures given in the illustration indi-
cate the recommended center of gravity
zone.
CAUTION
If a load is too far back, it can cause
dangerous handling. If it is too far
forward, the front axle may be over-
loaded.
Cargo weight rating
Two-wheel drive models
Normal cab models 1-ton models 907 kg (2000 lb.)
1/2-ton models 498 kg (1100 lb.)
Xtra-cab models 431 kg (950 lb.)
Four-wheel drive models Normal cab models 498 kg (1100 lb.)
Xtra-cab models 431 kg (950 lb.) When the truck is used to carry a slide-in
camper, the total cargo load of the truck
consists of the manufacturer ’s camper
weight figure, the weight of installed addi-
tional camper equipment not included in
the manufacturer ’s camper weight figure,
the weight of camper cargo and the
weight of passengers in the camper.
The total cargo load should not exceed
the truck’s cargo weight rating and the
camper ’s center of gravity should fall with-
in the truck’s recommended center of
gravity zone when installed.CAUTION
Be careful—overloading can cause
dangerous braking and handling prob-
lems, and can damage your vehicle
and its tires.
—Cargo weight rating
and proper matching

T100(U)213
Secure loose items to prevent weight
shifts that could affect the balance of your
vehicle. When the truck camper is loaded,
drive to a scale and weigh on the front
and on the rear wheels separately to de-
termine axle loads. Individual axle loads
should not exceed either of the Gross
Axle Weight Ratings (GAWR). The total of
the axle loads should not exceed the
Gross Vehicle Weight Rating (GVWR).The
GAWR and GVWR are indicated on the
Certification Label. See ”Your Toyota’s
identification” in Part 2 for the Certification
Label location.GAWR
