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 review this information to tow your load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty coverage, follow the requirements and recommendations in this manual concerning vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist you in understanding the following information:
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 not exceed the GVWR
The GTW is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or temporary) 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 allowable weight of your vehicle and trailer when weighed in
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 front or rear GAWR
The TW is the downward force exerted on the hitch ball by the trailer. You must consider this as part of the load on your vehicle.
The frontal area is the maximum height multiplied by the maximum width of the front of a trailer.
The TSC can be a mechanical 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.
If equipped, the electronic TSC recognizes a swaying trailer and automatically applies individual wheel brakes and/or reduces engine power to attempt to eliminate the trailer sway.
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 vehicle. These kinds of hitches are commonly used to tow small and medium sized trailers.
A weight-distributing system works by applying leverage 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, thereby enhancing towing safety. The addition of a friction/hydraulic sway control also dampens sway caused by traffic and crosswinds and contributes positively to tow vehicle and trailer stability. Trailer sway control and a weight distributing (load equalizing) hitch are
recommended for heavier Tongue Weights (TW) and may be required depending on vehicle and trailer configuration/loading to comply with GAWR requirements.

The vehicle must remain in the engine run posi- tion with all doors closed while attaching a trailer for proper leveling of the air suspension system.
For all towing conditions, we recommend towing with tow haul mode engaged.
TRAILER HITCH TYPE AND MAXIMUM TRAILER WEIGHT
The following chart provides the maximum trailer weight a given factory equipped trailer hitch type can tow and should be used to assist you in selecting the correct trailer hitch for your intended towing condition.
Trailer Hitch Type and Maximum Trailer Weight
Max. Trailer Weight / Max. Tongue Weight
Class III Bumper Hitch - 1500 Model
6,000 lbs (2,721 kg) / 500 lbs (226 kg)
Class IV - 1500 Model
12,750 lbs (5,783 kg) / 1,275 lbs (578 kg)
Refer to the “Trailer Towing Weights (Maximum Trailer Weight Ratings)” for the Maximum Gross Trailer Weight (GTW) towable for your given drivetrain.
All trailer hitches should be professionally installed on your vehicle.
Remove the cap with a trim stick or screw driver to access the Class III hitch attachment.
Be careful not to scratch the bumper step pad.
TRAILER TOWING WEIGHTS (MAXIMUM TRAILER WEIGHT RATINGS)
For trailer towing information (maximum trailer weight ratings) refer to the following website addresses:
TRAILER AND TONGUE WEIGHT
Consider the following items when computing the weight on the rear axle of the vehicle:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional factory-installed options or
dealer-installed options must be considered as part of the total load on your vehicle. Refer to the “Tire And Loading Information” placard for
the maximum combined weight of occupants and cargo for your vehicle.
TRAILER REVERSE STEERING CONTROL
Trailer Reverse Steering Control (TRSC) is a feature that will allow the driver to back up a trailer using a knob located on the center stack. The feature works by the user first hooking up a trailer and then performing the calibration maneuvers.
First bring the vehicle and trailer to a complete stop in a large open area, place the vehicle in PARK and push the TRSC button located above the knob in the center stack.
To calibrate a trailer, the driver must drive forward 100 ft (30 m). Then perform a 90 degree turn and return to a straight position for 65 ft (20 m). Perform another 90 degree turn, followed by another 65 ft (20 m) straight drive.
Upon completion this the feature will be available to activate.
The 90 degree turns could be in either the left or right direction.
Once calibrated the driver can shift to PARK, push the button on top of the TRSC knob and activate the feature. The knob is then turned either to the left or right depending on what direction the driver wants the trailer to go.
When steering the trailer with the knob, remove hands from the steering wheel.
There is also a holdover state where if during an active trailer steering maneuver, the driver shifts to NEURAL or DRIVE to straighten the trailer, the driver may shift back to REVERSE and not need to reactivate the feature. However the feature will cancel after 10 seconds or when the vehicle speed reaches 8 mph (12 km/h).
Other reasons the feature may cancel:
The trailer steering system can remember up to
five trailers, so recalibration will not be necessary.
To store a trailer to memory, calibrate the trailer and then allow the vehicle to be off for a period of time. The next time the vehicle is started, place the vehicle in DRIVE and drive a short distance. The trailer system can then be activated.
Trailers may look different during day and night conditions. In such cases, the trailer may need to recalibrate.
Some trailers (such as boat trailers) will need to recalibrate while loaded and unloaded.
To promote proper break-in of your new vehicle drivetrain components, the following guidelines are recommended.
Perform the maintenance listed in the Scheduled Servicing section for the proper maintenance intervals page 395. When towing a trailer, never exceed the GAWR or GCWR ratings.
Your vehicle may have an Integrated Trailer Brake Module (ITBM) for Electric and Electric Over Hydraulic (EOH) trailer brakes.
This module has been designed and verified with electric trailer brakes and new EOH systems. Some previous EOH systems may not be compatible with ITBM.
1 — GAIN (-) Adjustment Button 2 — GAIN (+) Adjustment Button 3 — Manual Brake Control Lever
The user interface consists of the following: GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control power output to the trailer brakes in
0.5 increments. The GAIN setting can be increased to a maximum of 10 or decreased to a minimum of 0 (no trailer braking).
The GAIN setting is used to set the trailer brake control for the specific towing condition and should be changed as towing conditions change. Changes to towing conditions include trailer load, vehicle load, road conditions and weather.
Slide the manual brake control lever to the left to activate power to the trailer's electric brakes independent of the tow vehicle's brakes. If the manual brake control lever is activated while the brake is also applied, the greater of the two inputs determines the power sent to the trailer brakes.
The trailer and the vehicle’s stop lamps will come on when braking normally with the vehicle brake pedal. Only the trailer stop lamps will come on when the manual brake control lever is applied.
This light indicates the trailer electrical connection status.
If no electrical connection is detected after the 4
ignition is turned on, pushing the GAIN
adjustment button or sliding the manual brake control lever will display the GAIN setting for 10 seconds and the “Trailer Brake Status Indicator Light” will not be displayed.
If a fault is detected in the trailer wiring or the Integrated Trailer Brake Module (ITBM), the “Trailer Brake Status Indicator Light” will flash.
This should only be performed in a traffic free environment at speeds of approximately 20–25 mph (30–40 km/h).
by the ITBM, braking functions will not be available), the GAIN setting will illuminate and the correct type of trailer must be selected from the instrument cluster display options.
Repeat steps 8 and 9 until the GAIN setting is at a point just below trailer wheel lockup. If towing a heavier trailer, trailer wheel lockup may not be attainable even with the maximum GAIN setting of 10.

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-pin and seven-pin wiring harness. Use a factory approved trailer harness and connector.
Do not cut or splice wiring into the vehicle’s wiring harness.
The electrical connections are all complete to the vehicle but you must connect the harness to a trailer connector. Refer to the following illustrations.

This feature will run the trailer lights through a sequence to check the trailer light function. It is available in the Instrument Cluster under the Trailer Tow menu page 118.
When activated the feature will enable all of the exterior lights sequentially for up to two minutes for time to walk around and verify functionality.
The following exterior lights will remain on for the entirety of the sequence:
During this time the following lights will sequence, each activating for three seconds:
This light check sequence will continue for a total of two minutes.
The sequence will only activate if the following conditions are met:
The sequence will cancel if any of the following conditions occur:
Before towing, practice turning, stopping, and backing up the trailer in an area located away from heavy traffic.
The DRIVE range can be selected when towing. The transmission controls include a drive strategy to avoid frequent shifting when towing. However, if frequent shifting does occur while in DRIVE, select TOW/HAUL mode or select a lower gear range (using the Electronic Range Select (ERS) shift control).
Using TOW/HAUL mode or selecting a lower gear range (using the ERS shift control) while operating the vehicle under heavy loading conditions will improve performance and
extend transmission life by reducing excessive shifting and heat build up. This action will also provide better engine braking.
To reduce potential for automatic transmission overheating, activate TOW/HAUL mode when driving in hilly areas, or select a lower gear range (using the (ERS) shift control) on more severe grades.
(16 km/h), disengage until you can get back to cruising speed.
To aid in attaching/detaching the trailer from the vehicle, the air suspension system can be used page 165.
The vehicle must remain in the engine running position while attaching a trailer for proper leveling of the air suspension system.
