WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position see the information below:

Tire and Loading Information Placard
This placard tells you important information about the:
1) number of people that can be carried in the vehicle
2) the total weight your vehicle can carry
3) the tire size designed for your vehicle4) the cold tire inflation pressures for the front, rear
and spare tires.
Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire’s load carrying capacity if you
adhere to the loading conditions, tire size and cold tire
inflation pressures specified on the Tire and Loading
Information placard and the Vehicle Loading section of
this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR’s) for the front and rear
axles must not be exceeded. For further information on
GAWR’s, vehicle loading and trailer towing, see the
Vehicle Loading section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or XXX

lbs.” 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 pounds” 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 kilograms or XXX pounds.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “XXX”
amount equals 1400 lbs. and there will be five 150 lb.
passengers in your vehicle, the amount of available cargo
and luggage load capacity is 650 lb. (since 5 x 150 = 750,
and 1400 – 750 = 650 lb.)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.
NOTE:The following table shows examples on how to
calculate total load, cargo/luggage and towing capacities
of your vehicle with varying seating configurations and
number and size of occupants. This table is for illustra-
tion purposes only and may not be accurate for the
seating and load carry capacity of your vehicle.
NOTE:For the following example the combined weight
of occupants and cargo should never exceed 865 lbs. (392
Kg).

CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
As with any vehicle, do not park or operate this vehicle in
areas where combustible materials such as grass or leaves
can come in contact with a hot exhaust system.
A scorching odor may be detected if you continue to run
a malfunctioning engine. The odor may indicate severe
and abnormal catalyst overheating. If this occurs, thevehicle should be stopped, the engine shut off and the
vehicle allowed to cool. Service, including a tune-up to
manufacturer’s specifications should be obtained imme-
diately.
To minimize the possibility of catalyst damage:
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed.
•Do not idle the engine for prolonged periods during
very rough idle or malfunctioning operating condi-
tions.
•Do not allow vehicle to run out of fuel.

Definitions
The following trailer towing related terminology defini-
tions will assist in understanding the subsequent sec-
tions:
GROSS COMBINATION WEIGHT RATING (GCWR)
is the total permissible weight of your vehicle and trailer
when weighed in combination. (Note that GCWR ratings
include a 68 kg (150 lb.) allowance for the presence of a
driver.) Tongue Weight (of a trailer) is the weight placed
on a vehicle’s trailer hitch by the trailer.
GROSS TRAILER WEIGHT (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 itsloaded and ready for operationcondition.
STARTING AND OPERATING 271

TRAILER SWAY CONTROLis a 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 un-
wanted trailer swaying motions while traveling.
CAUTION!
•During the first 500 miles (805 km) your new
vehicle is driven, do not tow a trailer. Doing so
may damage your vehicle.
•When first towing a trailer, limit your speed to 50
mph (80 km/h) during the first 500 miles (805 km)
of towing.
Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR,
or GCWR, ratings.Consider the following items when computing the
weight on the rear axle:
•The tongue weight of the trailer.
•The weight of any other type of cargo or equipment
put in or on your vehicle.
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 Certification label located at the
driver’s door for the Gross Vehicle Weight Rating.

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
•Be sure the trailer is loaded heavier in front, with 60%
to 65% of the weight in front of the axle(s). 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.
•Donotinterconnect the hydraulic brake system of
your vehicle with that of the trailer. This could cause
inadequate braking and possible personal injury.
•Trailer brakes are recommended for trailers over 1,000
lbs (454 kg) and required for trailers in excess of 2,000
lbs. (907 kg).
•Use an approved trailer harness and connector. If a
hitch is ordered, the proper wiring will be provided.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•Make certain that the load is secured in the trailer and
will not shift during travel. When trailering cargo that
cannot be fully secured, dynamic load shifts can occur
that may be difficult for the driver to control.
•All trailer hitches should be professionally installed on
your vehicle.
STARTING AND OPERATING 273

•Safety chains must always be used between your
vehicle and trailer.
•Connect trailer lighting and brakes using factory har-
nesses only. Do not cut or splice any wiring to the
brake circuits.
Trailer and Tongue Weight
Gross Trailer Weight (GTW) means the maximum allow-
able weight of the trailer plus the weight of all cargo and
equipment loaded on the trailer when in actual under-
way towing condition. The recommended way to mea-
sure GTW is to put your fully loaded trailer on a vehicle
scale. The entire weight of the trailer must be supported
by the scale.
Tongue Weight is the weight placed on the vehicle’s
trailer hitch by the trailer. Always load a trailer with 60%
to 65% of the weight in the front of the trailer. This places
10% to 15% of the GTW on the tow hitch of your vehicle.Trailer sway control and equalizing hitch are required for
tongue weights above 350 lbs. (159 kg).
Also, there are maximum tongue weight ratings that are
not to be exceeded, as follows:
•Class IV (the receiver hitch type) 1200 lbs (544 kg)
274 STARTING AND OPERATING

Gross Combined Vehicle Weight Rating (GCWR)
The Gross Combined Vehicle Weight Rating (GCWR) is
theMAXIMUMallowable weight of the towing vehicle,
including passengers and cargo, and the weight of the
loaded trailer. Calculate the maximum trailer weight
(MTW) by subtracting the towing vehicle’s weight, in-
cluding passengers, and cargo from GCWR.
Trailer Towing—Hitches:
With a Class IV Hitch, you can tow a trailer with a Gross
Trailer Weight of up to 8, 900 lbs. (4037 kg.) depending on
your vehicle equipment. The Trailer Tow Package in-
cludes the platform hitch receiver, and a 7 lead wiring
harness mounted on the hitch. Tongue weight must be
equal to at least 10% of GTW, but no more that 15% of
GTW.
NOTE: When towing a trailer, the following require-
ments must be adhered to:
•GCWR must not be exceeded
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
(4) ratings are not exceeded:
1.GVWR
2.GTW
3.Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight.)

Trailer Towing Requirements
All Dodge Durango trucks are intended to tow trailers up
to 2,000 lbs. (907 kg) without added equipment or
alterations to standard equipment. Your vehicle may be
factory equipped for safe towing of trailers over 2,000 lbs.
(907 kg) with the trailer tow package.The electrical part of
this package includes an instruction sheet and wiring
pigtail for an aftermarket electric trailer brake controller.
These items are stored in the glove box.
If you regularly pull a trailer, regardless of the trailer size,
stop and turn signals on the trailer are recommended for
motoring safety.
When the additional trailer lighting is connected to the
vehicle, the flasher does not provide an indication ofoutside lamp/bulb failure. Therefore, an occasional vi-
sual check around the vehicle is recommended. Once the
trailer is removed the above indication will return to the
vehicle.
WARNING!
The direct connection of hydraulic brake lines from
vehicle brake system to trailer system is not accept-
able. The extra load may cause brake failure and you
may be injured.
All Durango models are equipped with an Anti-Lock
Brake System and require an electrically actuated electric
brake controller. A blue colored connector for electric
brake hookup is located under the instrument panel
above the brake pedal.
