VEHICLE LOADING

Gross Vehicle Weight Rating (GVWR)

The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.

Payload

The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.

Gross Axle Weight Rating (GAWR)

The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.

Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension

components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.

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.

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.

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 insure 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.

334

STARTING AND OPERATING

CAUTION!

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. Also 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 coverage,
follow the requirements and recommendations in this
instruction 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. Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting And Operating” for further informa-
tion.

Gross Trailer Weight (GTW)

The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tempo-
rary) 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 lbs (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.

6

STARTING AND OPERATING

335

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. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting And Operating” for further infor-
mation.

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. 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

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 friction
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.

336

STARTING AND OPERATING

Weight-Distributing Hitch

A weight-distributing 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 addi-
tion 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 per-
formance, and could result in a collision.

• Weight Distributing Systems may not be compatible

with Surge Brake Couplers. Consult with your hitch
and trailer manufacturer or a reputable Recreational
Vehicle dealer for additional information.

Trailer Hitch Classification

CAUTION! (Continued)

tow hitch of your vehicle. Loads balanced over the
wheels or heavier in the rear can cause the trailer to
sway severely side 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.

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.

NOTE:

Remember that everything put into or on the

trailer adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the “Tire And Loading Information” placard for
the maximum combined weight of occupants and cargo for
your vehicle.

STARTING AND OPERATING

Towing Requirements

To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended.

CAUTION!

• Do not tow a trailer at all during the first 500 miles

(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.

• Then, during the first 500 miles (805 km) that a trailer

is towed, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps the engine
and other parts of the vehicle wear in at the heavier
loads.

Perform the maintenance listed in the “Scheduled Servic-
ing”. Refer to “Scheduled Servicing” in “Servicing And
Maintenance” for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or GCWR ratings.

WARNING!

Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:

• Make certain that the load is secured in the trailer

and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.

• When hauling cargo or towing a trailer, do not

overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, chassis structure or tires.

• Safety chains must always be used between your

vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.

• Vehicles with trailers should not be parked on a

grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in

WARNING! (Continued)

PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or

ⴖchockⴖ the trailer wheels.

• GCWR must not be exceeded.

• Total weight must be distributed between the tow

vehicle and the trailer such that the following four
ratings are not exceeded:

1. GVWR

2. GTW

3. GAWR

4. Tongue weight rating for the trailer hitch utilized.

Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact

spare tire.

• Do not drive more than 50 mph (80 km/h) when towing

while using a full size spare tire.

• Proper tire inflation pressures are essential to the safe

and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures.

• Check the trailer tires for proper tire inflation pressures

before trailer usage.

• Check for signs of tire wear or visible tire damage before

towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.

• When replacing tires, refer to “Tires” in “Servicing And

Maintenance” for the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity will
not increase the vehicle’s GVWR and GAWR limits.

Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or

vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.

• An electronically actuated trailer brake controller is

required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.

• Trailer brakes are recommended for trailers over

1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).

342

STARTING AND OPERATING

WARNING!

• Do not connect trailer brakes to your vehicle’s hy-

draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.

• Towing any trailer will increase your stopping dis-

tance. When towing, you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.

CAUTION!

If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.

Integrated Trailer Brake Module — If Equipped

Your vehicle may have an Integrated Trailer Brake Module
(ITBM) for Electric and Electric Over Hydraulic (EOH)
trailer brakes.

NOTE:

This module has been designed and verified with

electric trailer brakes and new electric over hydraulic
systems. Some previous EOH systems may not be compat-
ible with ITBM.

The user interface consists of the following:

Instruction Brake Control Lever

Slide the instruction brake control lever to the left to activate
power to the trailer’s electric brakes independent of the
tow vehicle’s brakes. If the instruction brake control lever is
activated while the brake is also applied, the greater of the
two inputs determines the power sent to the trailer brakes.

The trailer and the vehicle’s brake lamps will come on
when either vehicle braking or instruction trailer brakes are
applied.

Trailer Brake Status Indicator Light

This light indicates the trailer electrical connection status.

If no electrical connection is detected after the ignition is
turned on, pushing the GAIN adjustment button or sliding
the instruction brake control lever will display the GAIN
setting for 10 seconds and the “Trailer Brake Status Indi-
cator Light” will not be displayed.

If a fault is detected in the trailer wiring or the Integrated
Trailer Brake Module (ITBM), the “Trailer Brake Status
Indicator Light” will flash.

GAIN Adjustment Buttons (+/-)

Pushing these buttons will adjust the brake control power
output to the trailer brakes in 0.5 increments. The GAIN
setting can be increased to a maximum of 10 or decreased
to a minimum of 0 (no trailer braking).

GAIN

The GAIN setting is used to set the trailer brake control for
the specific towing condition and should be changed as
towing conditions change. Changes to towing conditions
include trailer load, vehicle load, road conditions and
weather.

Adjusting GAIN

NOTE:

This should only be performed in a traffic free

environment at speeds of approximately 20–25 mph
(30–40 km/h).

1. Make sure the trailer brakes are in good working

condition, functioning normally and properly adjusted.
See your trailer dealer if necessary.

2. Hook up the trailer and make the electrical connections

according to the trailer manufacturer’s instructions.

the screen.

8. In a traffic-free environment, tow the trailer on a dry,

level surface at a speed of 20–25 mph (30–40 km/h) and
squeeze the instruction brake control lever completely.

9. If the trailer wheels lockup (indicated by squealing

tires), reduce the GAIN setting; if the trailer wheels turn
freely, increase the GAIN setting.

Repeat steps 8 and 9 until the GAIN setting is at a point just
below trailer wheel lockup. If towing a heavier trailer,
trailer wheel lockup may not be attainable even with the
maximum GAIN setting of 10.

Display Messages

The trailer brake control interacts with the instrument
cluster display. Display messages, along with a single
chime, will be displayed when a malfunction is determined
in the trailer connection, trailer brake control, or on the
trailer. Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further information.

WARNING!

Connecting a trailer that is not compatible with the
ITBM system may result in reduced or complete loss of
trailer braking. There may be a increase in stopping
distance or trailer instability which could result in
personal injury.

CAUTION!

Connecting a trailer that is not compatible with the
ITBM system may result in reduced or complete loss of
trailer braking. There may be a increase in stopping
distance or trailer instability which could result in
damage to your vehicle, trailer, or other property.

NOTE:
• An aftermarket controller may be available for use with

trailers with air or electric-over-hydraulic trailer brake
systems. To determine the type of brakes on your trailer
and the availability of controllers, check with your
trailer manufacturer or dealer.

• Removal of the ITBM will cause errors and it may cause

damage to the electrical system and electronic modules
of the vehicle. See your authorized dealer if an aftermar-
ket module is to be installed.

Towing Requirements — Trailer Lights And Wiring

Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.

The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.

NOTE:

Do not cut or splice wiring into the vehicle’s wiring

harness.

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector. Refer
to the following illustrations.

NOTE:
• Disconnect trailer wiring connector from the vehicle

before launching a boat (or any other device plugged
into vehicle’s electrical connect) into water.

• Be sure to reconnect once clear from water area.

Automatic Transmission

Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
instructionly select a lower gear.

NOTE:

Using a lower gear while operating the vehicle

under heavy loading conditions, will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup. This action will also provide better
engine braking.

AutoStick
• When using the AutoStick shift control, select the high-

est gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.

• To prevent excess heat generation, avoid continuous

driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and road
conditions allow.

Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed

drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.

• Use speed control in flat terrain and with light loads to

maximize fuel efficiency.

Cooling System

To reduce potential for engine and transmission overheat-
ing, take the following actions:

City Driving
• In city traffic — while stopped, place the transmission in

NEUTRAL, but do not increase engine idle speed.

Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.
