STARTING AND OPERATING
Inflation Pressure
This is the cold tire inflation pressure for your vehicle
for all loading conditions up to full GAWR.
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 commer-
cial 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 axle. Weighing the vehicle may show that the
GAWR of either the front or rear axles 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 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 135.
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.
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 135.
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.
