Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/TransmissionFrontal AreaMax. GTW
(Gross Trailer Wt.) Max. Tongue Wt.
(See Note)
3.6L Automatic 22 sq ft (2.04 sq m) 1,000 lbs (454 kg) 100 lbs (45 kg)
5.7L Automatic 32 sq ft (2.97 sq m) 1,000 lbs (454 kg) 100 lbs (45 kg)
Refer to local laws for maximum trailer towing speeds
NOTE: The trailer tongue weight must be considered as part of the combined weight of occupants and
cargo, and it should never exceed the weight referenced on the “Tire and Loading Information” placard. Re-
fer to “Tire Safety Information” in “Starting and Operating” for further information.
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 sway
severelyside 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.

Towing Requirements
To promote proper break-in of your new vehicle drive-
train components the following guidelines are recom-
mended:
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.
WARNING!
Improper towing can lead to an injury collision.
Follow these guidelines to make your trailer towing
as safe as possible:
•Make certain that the load is secured in the trailer
and it 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 dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure, or tires.(Continued)

STARTING AND OPERATING 455

WARNING! (Continued)
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or 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 automatic
transmission in PARK. Always, block orchock
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. Max loading as defined on the “Tire and Load-
ing Information” placard.
(Continued)
WARNING! (Continued)
2. GTW
3. GAWR
4. 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.)
Towing Requirements – Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for information on tire pressures and for proper
tire inflation procedures.
456 STARTING AND OPERATING

Check the trailer tires for proper tire inflation pres-
sures 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 informa-
tion on tread wear indicators and for the proper
inspection procedure.
When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for information
on replacement tires and for the proper tire replace-
ment procedures. Replacing tires with a higher load
carrying capacity will not increase the vehicle’s GVWR
and GAWR limits.
Towing Requirements – Trailer Brakes

Donot interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller 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
2,000 lbs (907 kg).
5
STARTING AND OPERATING 457

CAUTION!
If the trailer weighs more than 1,000 lbs (454 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.
WARNING!
•Do not connect trailer brakes to your vehicle’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
collision.(Continued)
WARNING! (Continued)
•Towing any trailer will increase your stopping
distance. When towing, you should allow for ad-
ditional space between your vehicle and the ve-
hicle in front of you. Failure to do so could result
in a collision.
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 har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
458 STARTING AND OPERATING

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, select
a lower gear using the AutoStickshift control (if
equipped).
NOTE: Selecting a lower gear while operating the
vehicle under heavy operating conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup. This action will also
provide better engine braking.
If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the automatic
transmission fluid and filter according to the interval specified for “police, taxi, fleet, or frequent trailer tow-
ing.” 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 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.
AutoStick
– If Equipped

By using the AutoStick mode and selecting a specific
gear, frequent shifting can be avoided. Select the
highest gear that allows for adequate performance and
avoids frequent downshifts.
460 STARTING AND OPERATING

Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear or vehicle speed
when road conditions and RPM level allows.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
RECREATIONAL TOWING
(BEHIND MOTORHOME, ETC.)
Two-Wheel Drive and All-Wheel Drive
Recreational towing (with all four wheels on the ground,
or using a tow dolly) is NOT ALLOWED. The only
acceptable method for towing this vehicle (behind an-
other vehicle) is on a vehicle trailer with all four wheels
OFF the ground.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe transmission and/or transfer
case damage. Such damage is not covered by the New
Vehicle Limited Warranty.
