Ram C/V 2013 Owner's Manual

The label contains the following information:
•Name of manufacturer
• Month and year of manufacture
• Gross Vehicle Weight Rating (GVWR)
• Gross Axle Weight Rating (GAWR) front
• Gross Axle Weight Rating (GAWR) rear
• Vehicle Identification Number (VIN)
• Type of Vehicle
• Month Day and Hour of Manufacture (MDH)
The bar code allows a computer scanner to read the VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
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!
Because the front wheels steer the vehicle, 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
control of the vehicle and have a collision.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.

STARTING AND OPERATING 549

Rim Size
This is the rim size that is appropriate for the tire size
listed.
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.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
550 STARTING AND OPERATING

Loading
To load your vehicle properly, first figure out its empty
weight, axle-by-axle and side-by-side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
NOTE:Refer to the “Vehicle Certification Label” affixed
to the rear of the driver’s door for your vehicle’s GVWR
and GAWRs.
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 coverage,
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
5
STARTING AND OPERATING 551

exceed the GVWR. Refer to “Vehicle Loading/Vehicle
Certification Label” in “Starting and Operating” for
further information.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in itsloaded 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. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting and Operating” for further
information.
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
control of the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. In most cases it should not be
more than 10% of the trailer load. You must consider this
as part of the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
552 STARTING AND OPERATING

Trailer Sway Control
The trailer sway control can be a mechanical telescoping
link that can be installed between the hitch receiver and
the trailer tongue that typically provides adjustable fric-
tion associated with the telescoping motion to dampen
any unwanted trailer swaying motions while traveling.
If equipped, the electronic Trailer Sway Control (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 the most popular on the market today and
they are commonly used to tow small and medium sized
trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying lever-
age 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’s 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 and a weight distributing (load
equalizing) hitch are recommended for heavier tongue
weights (TW), and may be required depending on vehicle
and trailer configuration/loading to comply with gross
axle weight rating (GAWR) requirements.

WARNING!
•An improperly adjusted weight-distributing hitch
system may reduce handling, stability, braking
performance, and could result in a collision.
• Weight-distributing hitch systems may not be com-
patible with surge brake couplers. Consult with an
authorized hitch and trailer manufacturer or a
reputable authorized Recreational Vehicle dealer
for additional information.

STARTING AND OPERATING 557

NOTE:The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire
and Loading Information placard. Refer to “Tire Safety
Information” in “Starting and Operating” for further
information.
Trailer And Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to sway severelyside to side
which will cause loss of control of the vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer collisions.
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch. Consider the following items when computing the
weight on the rear axle of the vehicle:
•
The tongue weight of the trailer.
• The weight of any other type of cargo or equipment
put in or on your vehicle.
• The weight of the driver and all passengers.
