Trailer Towing Weights (Maximum Trailer Weight Ratings)The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/TransmissionMax. GTW (Gross Trailer Wt.) —
with Trailer Brake Max. GTW (Gross Trailer Wt.) —
without Trailer Brake Tongue Wt. (See Note)
3.6L Gasoline 5,000 lbs (2 268 kg) 1,653 lbs (750 kg)249 lbs (113 kg)
5.7L Gasoline 7,716 lbs (3 500 kg) 1,653 lbs (750 kg)386 lbs (175 kg)
3.0L Diesel 7,716 lbs (3 500 kg) 1,653 lbs (750 kg)386 lbs (175 kg)
Maximum trailer towing speed is limited to 62 mph (100 km/h) unless local laws require a lower speed.
NOTE:
The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight refer-
enced on the Tire and Loading Information placard. Refer to “Tires – General Information” in “Starting and Operating” for further information.
Trailer And Tongue WeightAlways load a trailer with 60% of the weight in
the front of the trailer. 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 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
trailer hitch. Consider the following items when computing
the weight on the front/rear axles of the vehicle:
•
The trailer 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.
281

NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options, or au-
thorized dealer-installed options, must be
considered as part of the total load on your
vehicle. Refer to the tire loading information
placard located on the drivers door pillar for
the maximum combined weight of occu-
pants and cargo for your vehicle.
Towing RequirementsTo 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.
(Continued)
CAUTION!(Continued)
•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 “Mainte-
nance Schedule.” Refer to “Maintenance Sched-
ule” for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or
GCWR ratings.
WARNING!
Improper towing can lead to a collision. Fol-
low 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

WARNING!(Continued)
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. Over-
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspen-
sion, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always con-
nect the chains to the hook retainers of the
vehicle hitch. Cross the chains under the
trailer tongue and allow enough slack for
turning corners.

282

WARNING!(Continued)
•Vehicles with trailers should not be parked
on a grade. When parking, apply the park-
ing brake on the tow vehicle. Put the tow
vehicle transmission in PARK. For four-
wheel drive vehicles, make sure the trans-
fer case is not in NEUTRAL. Always, block
or "chock" the trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed be-
tween the tow vehicle and the trailer
such that the following four ratings are
not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Trailer tongue weight rating for the trailer hitch utilized . Towing Requirements – Tires
•
Proper tire inflation pressures are essential
to the safe and satisfactory operation of your
vehicle. Refer to “Tires – General Informa-
tion” in “Starting and Operating” 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 – General Information” in “Starting and
Operating” for proper inspection procedure.
• When replacing tires, refer to “Tires – Gen-
eral Information” in “Starting and Operating”
for proper tire replacement procedures. Re-
placing tires with a higher load carrying ca-
pacity will not increase the vehicle’s GVWR
and GAWR limits.
Towing Requirements – Trailer Brakes
• Do not interconnect the hydraulic brake sys-
tem or vacuum system of your vehicle with
that of the trailer. This could cause inad-
equate braking and possible personal injury. •
An electronically-actuated trailer brake con-
troller is required when towing a trailer with
electronically-actuated 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 (454 kg), and required for
trailers in excess of 1,654 lbs (750 kg).
WARNING!
•Do not connect trailer brakes to your vehi-
cle’s hydraulic brake lines. It can overload
your brake system 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
distance. 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.
283

Towing Requirements – Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the
trailer size, stop lights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package includes a 13 pin
wiring harness. Use a factory approved trailer
harness and connector.
NOTE:
Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to a
trailer connector.

Towing TipsBefore setting out on a trip, practice turning,
stopping and backing the trailer in an area away
from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include an adaptive
drive strategy to avoid frequent shifting when
towing. However, if frequent shifting does occur
while in DRIVE, select TOW mode, or use the
AutoStick® shift control to select a lower gear.
NOTE:
Using TOW mode or selecting a lower gear
while operating the vehicle under heavy load-
ing conditions, will improve performance and
extend transmission life by reducing exces-
sive shifting and heat buildup. This action will
also provide better engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then change
the transmission fluid and filter(s) as specified for
"police, taxi, fleet, or frequent trailer towing. Refer
to the “Maintenance Schedule” for the proper
maintenance intervals.
Electronic Speed Control – If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experi-
ence 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
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift the
transmission into NEUTRAL and increase en-
gine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
