TRAILER TOWING
In this section, you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer carefully re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do notexceed the GVWR. Refer to “Vehicle Loading/Vehicle
Certification Label” in “Starting and Operating” for
further information.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in its
loaded and
ready for operation condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight
of the trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
NOTE: The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.

STARTING AND OPERATING 467

Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either the front
or rear GAWR. Refer to “Vehicle Loading/Vehicle Certi-
fication Label” in “Starting and Operating” for further
information.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. In most cases it should not be less
than 10% or more than 15% of the trailer load. You must
consider this as part of the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control
The trailer sway control is a telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball or
some other connecting point of the truck. These kind of
hitches are the most popular on the market today and
they are commonly used to tow small- and medium-
sized trailers.
468 STARTING AND OPERATING

Weight-Distributing Hitch
A weight-distributing hitch system works by applying le-
verage through spring (load) bars. They are typically used
for heavier loads, to distribute trailer tongue weight to the
tow vehicle’s front axle and the trailer axle(s). When used in
accordance with the manufacturer’s directions, it provides
for a more level ride, offering more consistent steering and
brake control and thereby enhancing towing safety. The
addition of a friction/hydraulic sway control also dampens
sway caused by traffic and crosswinds, contributing posi-
tively to tow vehicle and trailer stability. Trailer sway control
and a weight distributing (load equalizing) hitch are recom-
mended for heavier Tongue Weights (TW) and may be
required depending on Vehicle and Trailer configuration/
loading to comply with GAWR requirements.
Trailer Hitch Classification
The following chart provides the industry standard for
the maximum trailer weight a given trailer hitch class can
tow and should be used to assist you in selecting thecorrect trailer hitch for your intended towing condition.
Refer to the Trailer Towing Weights (Maximum Trailer
Weight Ratings) chart for the Maximum GTW towable
for your given drivetrain.
Trailer Hitch Classification Definitions
Class Max. Trailer Hitch
Industry Standards
Class I - Light Duty 2,000 lbs (907 kg)
Class II - Medium Duty 3,500 lbs (1 587 kg)

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
1.4L Turbo Engine
Trailer towing is not recommended.
Engine/Transmission Frontal Area Max. GTW (Gross Trailer Wt.) Max. Tongue Wt. (SeeNote)
2.0L and 2.4L Auto/
Man 22 sq ft (2.04 sq m)
1,000 lbs (450 kg) 150 lbs (50 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 should never exceed the weight referenced on the Tire and Loading Information placard. Refer 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 GTW
on the tow hitch of your vehicle. Loads balanced over the
wheels or heavier in the rear can cause the trailer to sway severely
from side-to-side which will cause loss of con-
trol of vehicle and trailer. Failure to load trailers heavier
in front is the cause of many trailer collisions.
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
470 STARTING AND OPERATING

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.
Perform the maintenance listed in the Maintenance
Schedule. Refer to “Maintenance Schedule” for further
information. When towing a trailer, never exceed the
GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. 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, 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 the brakes, axle, engine, transmission, steer-
ing, suspension, chassis structure or tires. (Continued)
472 STARTING AND OPERATING

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. With a manual transmis-
sion, shift the transmission into REVERSE. Al-
ways block orchockthe 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. GVWR
(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 proper tire inflation procedures.
Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
5
STARTING AND OPERATING 473

Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements – Trailer Brakes

Do not 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 (450 kg) and required for trailers in excess of
2,000 lbs (907 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs (450 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.
474 STARTING AND OPERATING

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 a
collision.
•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,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four-pin and
seven-pin wiring harness. Use a factory approved trailer
harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s
wiring harness.
The electrical connections are all complete to the vehicle,
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

STARTING AND OPERATING 475

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Manual Transmission – If Equipped
If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission – If Equipped
The DRIVE range can be selected when towing. How-
ever, if frequent shifting or changes in engine speed occur
while in this range, use the AutoStickshift control to
select a lower gear ratio.
NOTE: Using a lower gear ratio while operating the
vehicle under heavy loading 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 minutes of continuous operation,
then change the transmission fluid and filter as specified
for
police, taxi, fleet, or frequent trailer towing. Refer to
the Maintenance Schedule for the proper maintenance
intervals.
AutoStick
When using the AutoStick shift control, select the high-
est gear that allows for adequate performance and avoids
frequent downshifts. For example, choose 4if the
desired speed can be maintained. Choose 3or2 if
needed to maintain the desired speed.
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
grade or road conditions allow.
