CURB WEIGHT
The curb weight of a vehicle is defined as the total weight of
the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
LOADING
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to ensure that the GVWR has not been exceeded. The
weight on the front and rear of the vehicle should then be
determined separately to be sure that the load is properly
distributed over the front and rear axles. Weighing the
vehicle may show that the GAWR of either the front or rear
axle has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from front to
rear or rear to front as appropriate until the specified weight
limitations are met. Store the heavier items down low and
be sure that the weight is distributed equally. Stow all loose
items securely before driving.
Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles and
the way the brakes operate.
WARNING!
Do not load your vehicle any heavier than the GVWR,
maximum Payload or the maximum front and rear
GAWR. If you do, parts on your vehicle can break, or it
can change the way your vehicle handles. This could
cause you to lose control. Overloading can shorten
the life of your vehicle.
TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer, carefully
review this information to tow your load as efficiently
and safely as possible.
To maintain the New Vehicle Limited Warranty cover-
age, follow the requirements and recommendations in
this manual concerning vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing-related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do
not exceed the GVWR
page 155.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of
all cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its "loaded and
ready for operation" condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight
of the trailer must be supported by the scale.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg) or
more, it is recommended to use a weight-distributing
hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
Gross Combination Weight Rating
(GCWR)
The GCWR is the total allowable weight of your vehicle
and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and
rear axles. Distribute the load over the front and rear
axles evenly. Make sure that you do not exceed either
front or rear GAWR
page 155.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose con-
trol of the vehicle and have a collision.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball
by the trailer. You must consider this as part of the load
on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by
the maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that can
be installed between the hitch receiver and the trailer
tongue that typically provides adjustable friction associ-
ated with the telescoping motion to dampen any
unwanted trailer swaying motions while traveling.
