Trailer Towing Weights (Maximum Trailer Weight Ratings)The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/Transmission Max. GTW (Gross Trailer Wt.) — withTrailer BrakeMax. 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
referenced on the Tire and Loading Information placard. Refer to “Tires – General Information” in “Starting and Operating” for further information.
Trailer And Trailer 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.
NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options, or au-
246

thorized dealer-installed options, must be
considered as part of the total load on 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.
• 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
Schedule” for the proper maintenance inter-
vals. When towing a trailer, never exceed the
GAWR or GCWR ratings.
WARNING!
Improper towing can lead to an injury acci-
dent. Follow 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, dy-
namic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have an accident.
• 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.
(Continued)
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.
247

Check the trailer tires for proper tire inflationpressures 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
capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes
Do notinterconnect 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).
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 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 stop-
ping 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. 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.

JACKING AND TIRE CHANGING
WARNING!
•Getting under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the jack
and fall on you. You could be crushed.
Never get any part of your body under a
vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service
center where it can be raised on a lift.
• The jack is designed to be used as a tool
for changing tires only. The jack should not
be used to lift the vehicle for service pur-
poses. The vehicle should be jacked on a
firm, level surface only. Avoid ice or slippery
areas.
Jack LocationThe scissor-type jack and tire changing tools
are located in rear cargo area, below the load
floor.
Spare Tire StowageThe spare tire is stowed under the load floor in
the rear cargo area.
Preparations for Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery surfaces.
WARNING!
Do not attempt to change a tire on the side of
the vehicle closest to moving traffic. Pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel. 2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK.
5. Turn the ignition OFF.
6. Block both the front
and rear of the wheel
diagonally opposite of
the jacking position. For
example, if changing
the right front tire, block
the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.
7. For vehicle equipped with Quadra-Lift refer
to “Quadra-Lift — If Equipped” in “Starting and
Operating” for further information on disabling
automatic leveling.

(Continued)
WARNING!(Continued)
• If working on or near a roadway, be ex-
tremely careful of motor traffic.
• To assure that spare tires, flat or inflated,
are securely stowed, spares must be
stowed with the valve stem facing the
ground.
1. Remove the spare tire, jack, and tools from
storage.
2. Loosen (but do not remove) the wheel lug
nuts by turning them to the left, one turn, while
the wheel is still on the ground.
3. Assemble the jack and jacking tools. 4. For a front tire, place the jack and protective
cap on the body flange just behind the front tire
(as indicated by the triangular lift point symbol
on the sill molding).
Do not raise the vehicle
until you are sure the jack is fully engaged.
