{Warning
Never load the roof rack
with more weight than
specified in this section.
Loading cargo on the roof
rack will make the vehicle's
center of gravity higher. To
avoid losing control of the
vehicle, avoid overloading,
high speeds, sudden starts,
sharp turns, sudden braking,
or abrupt maneuvers when
carrying cargo on the
roof rack.
The weight of any cargo
carried on the roof rack
system must be included in
calculating the loaded weight
of the vehicle. Do not exceed
the maximum vehicle capacity
when loading the vehicle,
including cargo carried on the roof rack system and
passengers and cargo carried
in the vehicle. For more
information on vehicle
capacity and loading, see
Vehicle Load Limits
0252.

252 Driving and Operating
the transmission is in gear.
Slowly spinning the wheels in
the forward and reverse
directions causes a rocking
motion that could free the
vehicle. If that does not get
the vehicle out after a few
tries, it might need to be
towed out. If the vehicle does
need to be towed out, see
Transporting a Disabled
Vehicle0437.
Vehicle Load Limits
It is very important to know
how much weight the
vehicle can carry. This
weight is called the vehicle
capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed
options. Two labels on the
vehicle may show how
much weight it may
properly carry, the Tire and Loading Information label
and the Certification/Tire
label.
{Warning
Do not load the vehicle
any heavier than the
Gross Vehicle Weight
Rating (GVWR), or either
the maximum front or
rear Gross Axle Weight
Rating (GAWR). This can
cause systems to break
and change the way the
vehicle handles. This
could cause loss of
control and a crash.
Overloading can also
reduce stopping
performance, damage the
tires, and shorten the life
of the vehicle.
Tire and Loading Information
Label
Example Label
A vehicle-specific Tire and
Loading Information label is
attached to the center
pillar (B-pillar). The tire and
loading information label
shows the number of
occupant seating
positions (1), and the
maximum vehicle capacity
weight (2) in kilograms and
pounds.

The Tire and Loading
Information label also
shows the size of the
original equipment tires (3)
and the recommended cold
tire inflation pressures (4).
For more information
on tires and inflation see
Tires0400 and
Tire Pressure 0408.
There is also important
loading information on the
vehicle Certification/Tire
label. It may show the
Gross Vehicle Weight
Rating (GVWR) and the
Gross Axle Weight Rating
(GAWR) for the front and
rear axle. See
“Certification/Tire Label”
later in this section.
“Steps for Determining
Correct Load Limit– 1.
Locate the statement
"The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs." on
your vehicle’s placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from
XXX kg or XXX lbs.
4.The resulting figure
equals the available
amount of cargo and
luggage load capacity.
For example, if the
"XXX" amount equals
1400 lbs. and there will
be five 150 lb
passengers in your
vehicle, the amount of
available cargo and
luggage load capacity is
650 lbs. (1400-750 (5 x
150) = 650 lbs.)
5.Determine the combined
weight of luggage and
cargo being loaded on
the vehicle. That weight
may not safely exceed
the available cargo and
luggage load capacity
calculated in Step 4.
6.If your vehicle will be
towing a trailer, load
from your trailer will be
transferred to your
vehicle. Consult this
manual to determine
how this reduces the
available cargo and
luggage load capacity of
your vehicle.”
See Trailer Towing 0351
for important information
on towing a trailer, towing
safety rules and
trailering tips.

combined weight of the
driver, passengers, and
cargo should never exceed
the vehicle's capacity
weight.
Certification/Tire Label
Label Example
A vehicle-specific
Certification/Tire label is
attached to the center
pillar (B-pillar).
The label may show the
size of the vehicle's original
tires and the inflationpressures needed to obtain
the gross weight capacity
of the vehicle. The label
shows the gross weight
capacity of the vehicle. This
is called the Gross Vehicle
Weight Rating (GVWR). The
GVWR includes the weight
of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label
may also show the
maximum weights for the
front and rear axles, called
the Gross Axle Weight
Rating (GAWR). To find out
the actual loads on the
front and rear axles, weigh
the vehicle at a weigh
station. Your dealer can
help with this. Be sure to
spread the load equally on
both sides of the
centerline.
Caution
Overloading the vehicle may
cause damage. Repairs
would not be covered by the
vehicle warranty. Do not
overload the vehicle.
{Warning
Things inside the vehicle
can strike and injure
people in a sudden stop
or turn, or in a crash.
.Put things in the cargo
area of the vehicle. In
the cargo area, put
them as far forward as
possible. Try to spread
the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so
that some of them are
above the tops of the
seats.

3. Add the weight of allpassengers.
4. Add the weight of all cargo in the vehicle.
5. Add the weight of hitch hardware such as a draw
bar, ball, load equalizer
bars, or sway bars.
6. Add the weight of any accessories or aftermarket
equipment added to the
vehicle.
The resulting weight cannot
exceed the GCWR value
shown on the Trailering
Information Label.
The gross combined weight
can also be confirmed by
weighing the truck and trailer
on a public scale. The truck
and trailer should be loaded
for the trip with passengers
and cargo.
Gross Vehicle Weight
Rating (GVWR)
For information about the
vehicle's maximum load
capacity, see Vehicle Load
Limits 0252. When calculating
the GVWR with a trailer
attached, the trailer tongue
weight must be included as
part of the weight the vehicle
is carrying.
Maximum Trailer Weight
The maximum trailer weight
rating is calculated assuming
the tow vehicle has a driver, a
front seat passenger, and all
required trailering equipment.
This value represents the
heaviest trailer the vehicle can
tow, but it may be necessary
to reduce the trailer weight to
stay within the GCW, GVWR,
maximum trailer tongue load,
or GAWR-RR for the vehicle.
Use the tow rating chart to
determine how much the
trailer can weigh, based on the
vehicle model and options.

Association. (2) Tire Width
:The 3-digit
number indicates the tire
section width in millimeters
from sidewall to sidewall.
(3) Aspect Ratio
:A 2-digit
number that indicates the
tire height-to-width
measurements. For
example, if the tire size
aspect ratio is 75, as
shown in item (3) of the
illustration, it would mean
that the tire's sidewall is
75 percent as high as it
is wide.
(4) Construction Code
:A
letter code is used to
indicate the type of ply
construction in the tire. The
letter "R" means radial ply
construction; the letter "D"
means diagonal or bias ply
construction.
(5) Rim Diameter
:
Diameter of the wheel in
inches. (6) Service Description
:
These characters
represent the load index
and speed rating of the
tire. The load index
represents the load
carrying capacity a tire is
certified to carry. The
speed rating is the
maximum speed a tire is
certified to carry a load.
