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.
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.
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.
If equipped, the electronic TSC recognizes a swaying
trailer and automatically applies individual wheel
brakes and/or reduces engine power to attempt to
eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball
or some other connecting point of the vehicle. These
kinds of hitches are commonly used to tow small and
medium sized trailers.
Weight-Distributing Hitch
A weight-distributing hitch system works by applying
leverage through spring (load) bars. They are typically
used for heavier loads to distribute trailer tongue weight
to the tow vehicle's front axle and the trailer axle(s).
When used in accordance with the manufacturer's
directions, it provides for a more level ride, offering
more consistent steering and brake control, thereby
enhancing towing safety. The addition of a friction/
hydraulic sway control also dampens sway caused by
traffic and crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer Sway Control (TSC)
and a weight-distributing (load equalizing) hitch are rec-
ommended for heavier Tongue Weights (TW) and may
be required depending on vehicle and trailer
configuration/loading to comply with GAWR
requirements.
