in this mode. This mode should be used for almost all
driving situations. ESP should only be turned to “Partial
Off” for specific reasons as noted below.
Partial Off
This mode is entered by momentarily depressing the ESP
OFF switch. When in “Partial Off” mode, the enginemanagement portion of ESP has been desensitized, the
thresholds for ESP activation are raised, and the “ESP/
TCS Indicator Light” will be illuminated. This mode is
intended to be used if the vehicle is in deep snow, sand or
gravel conditions and more wheel spin than ESP would
normally allow is required to gain traction. Trailer Sway
Control (TSC) is not available when the system is in the
Partial Offmode. To turn ESP on again, momentarily
depress the ESP OFF switch. This will restore the normal
ON mode of operation. ESP always operates under
braking, even with the switch in the OFF position.
WARNING!
In the “Partial Off” mode, the engine torque reduc-
tion and stability features are desensitized. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.

WARNING!
In the “Partial Off” mode, the engine torque reduc-
tion and stability features are desensitized. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize a swaying
trailer and will take the appropriate actions to attempt to
stop the sway. The system will reduce engine power and
apply individual brakes that will counter act the sway of
the trailer. TSC will become active automatically once the
swaying trailer is recognized. No driver action is re-
quired. TSC cannot stop all trailers from swaying. Al-
ways use caution when towing a trailer and follow the
tongue weight recommendations. For additional infor-
mation on towing a trailer with your vehicle, refer to
Trailer Towingin Section 5.
ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow ESP/BAS Warning Light
and the yellow ESP/TCS Indicator Light in the instru-
ment cluster both come on when the ignition switch is
turned to the ON position. They should both go out with
the engine running. If the ESP/BAS Warning Light comes
on continuously with the engine running, a malfunction
has been detected in either the ESP or BAS system, or
both. If this light remains on after several ignition cycles,
and the vehicle has been driven several miles at speeds
greater than 30 mph (48 km/h), see your authorized
dealer as soon as possible to have the problem diagnosed
and corrected.
NOTE:
•The ESP Indicator Light and the ESP/BAS Warning
Light come on momentarily each time the ignition
switch is turned ON.

axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
“Vehicle Loading” in this section.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX lbs or
XXX kg” on the Tire and Loading Information placard.
The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight of occu-
pants and cargo should never exceed XXX lbs or XXX kg”
on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.3. Subtract the combined weight of the driver and pas-
sengers from XXX lbs or XXX kg.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “XXX”
amount equals 1,400 lbs (635 kg) and there will be five
150 lb (68 kg) passengers in your vehicle, the amount of
available cargo and luggage load capacity is 650 lbs
(295 kg) (since 5 x 150 = 750, and 1400 – 750 = 650 lbs
[295 kg]).
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity
calculated in step 4.
6. If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. Consult this
manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.

should then be determined separately to be sure that the
load is properly distributed over 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 heavier items down low and be sure that the weight
is distributed equally. Stow all loose items securely before
driving.
Improper weight distribution 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. 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 re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles 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 tem-
porary) loaded in or on the trailer in itsloaded and
ready for operationcondition. 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 Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination. (Note that
GCWR ratings include a 150 lbs (68 kg) allowance for the
presence of a driver.)
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
control of the vehicle and have an accident.

Trailer Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball
by the trailer. In most cases it should not be less than 10%
or more than 15% 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 and maximum
width of the front of a trailer.
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 kind of
hitches are the most popular on the market today and
they’re commonly used to tow small- and medium-sized
trailers.
Weight-Distributing Hitch
A weight-distributing hitch works by applying leverage
through spring (load) bars. They are typically used forheavier loads, to distribute trailer tongue weight to the
tow vehicle’s front axle and the trailer axle(s). When used
in accordance with the manufacturers’ directions, it pro-
vides 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 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
may reduce handling, stability, and braking perfor-
mance, and could result in an accident.

and trailer manufacturer or a reputable recreational
vehicle dealer for additional information.
Trailer Hitch Classification
The rear bumper is intended to tow trailers up to
2,000 lbs (907 kg) without added equipment or alter-
ations to the standard equipment. Your vehicle may be
factory equipped for safe towing of trailers weighing
over 2,000 lbs (907 kg) with the optional Trailer Tow Prep
Package. See your authorized dealer for package content.
The following chart provides the industry standard for
the maximum trailer weight a given trailer hitch class can
tow and should be used to assist you in selecting the
correct trailer hitch for your intended towing condition.

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 swayseverelyside to side
which will cause loss of control of vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents.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.
