2005 DODGE POWER WAGON trailer

With a Class III Hitch, your vehicle can be equipped to
tow trailers with a Gross Trailer Weight (GTW) of 5,000
lbs (2 268 kg) maximum. Factory-installed rear step
bumpers are rated a Class III hitch.
A frame mounted hitch of up to Class IV rating, as rated
by the hitch manufacturer, may also be installed. With a
Class IV Hitch, you can tow a trailer with a Gross Trailer
Weight of up to 12,000 lbs (5 443 kg) maximum depend-
ing on your vehicle equipment.
Connecting Trailer Lighting And Electric Trailer
Brakes
NOTE:A 4-way trailer tow connector, located behind
the bumper, is standard equipment on all Ram pickup
models. This connector contains the following vehicle
circuits: park/tail lamps, left stop/turn lamp, right stop/
turn lamp, and ground. With the optional Trailer TowPrep package a 7-way connector is also provided with the
following additional circuits: backup lamp, trailer battery
and electric brake.
NOTE:There is also a 4–way connector located under
the instrument panel, located to the left of the brake
pedal that is used for the electric brake. This connector
contains the following vehicle circuits; power ground,
battery, stop lamp switch and electric brake feed. The
4–way is optional with the trailer tow prep package.
322 STARTING AND OPERATING

CAUTION!
Adding lights or electrical devices to the headlamp/
park lamp circuit can be accomplished by connecting
to the standard 4-way trailer tow connector located
behind the rear bumper. The maximum current ca-
pacity for the park lamp circuit should not exceed 15
amps total (a typical park lamp bulb can draw from
0.5 to 1.0 amperes of current).
No connections can be made to the headlamp switch
itself, because it is not designed for high current
applications. Connections to the headlamp switch
will cause the exterior lights to malfunction.
CAUTION!
Connect trailer lighting and brakes using factory
harnesses only. Do not cut or splice wiring to the
brake circuits. Use an approved wiring harness con-
nector on the trailer.
Trailer Weight and Trailer Tongue Weight
Gross Trailer Weight (GTW) means the weight of the
trailer plus the weight of all cargo, consumables 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.
STARTING AND OPERATING 323

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
Class III or IV trailer hitches and tongue weights above
350 lbs (159 kg).Tongue weight must be equal to at least 10% of GTW, but
no more than 15% of GTW.
Also, there are maximum tongue weight ratings that are
not to be exceeded, as follows:
•Class III (the bumper ball type) 500 lbs (227 kg)
•Class IV (the receiver hitch type) 1200 lbs (544 kg)
NOTE: When towing a trailer, the following require-
ments must be adhered to:
•GCWR must not be exceeded
324 STARTING AND OPERATING

•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 Mirrors—If Equipped
These mirrors are designed with an adjustable mirror
head to provide a greater vision range when towing
extra-wide loads. To change position inboard or out-
board, the mirror head should be rotated (flipped Out or
In). A small blindspot mirror is integrated onto the main
mirror surface.
Cooling System Tips—Trailer Towing
To reduce potential for engine and transmission over-
heating, take the following actions:
•City Driving—when stopped, put the transmission in
N (Neutral) and increase the engine idle speed.
•Highway Driving—reduce your speed.
326 STARTING AND OPERATING

•More than 50% of your driving is at sustained high
speeds during hot weather, above 32°C (90°F)
•Trailer towing
•Heavy Loading
•Taxi, Police or delivery service (commercial service)
•Off-road or desert operation
•If equipped for and operating with E-85 (ethanol)
fuel.
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule“B”of the
Maintenance Schedulessection of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on scheduleAof theMainte-
nance Schedulessection of this manual.
Dusty Conditions
Driving through dust-laden air increases the problems of
keeping abrasive materials out of the engine. Under these
conditions, special attention should be given to the
engine air cleaner, the crankcase inlet air cleaner and the
crankcase ventilation system. Make sure that these units
are clean at all times. This will tend to reduce to a
minimum the amount of abrasive material that may enter
the engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacture only
recommends engine oils that are API certified and meet
the requirements of DaimlerChrysler Material Standard
MS-6395. Use Mopar or an equivalent oil meeting the
specification MS-6395.
