TOWING A TRAILER
WARNING: Towing trailersbeyond the maximum recommendedgross trailer weight exceeds the limitof your vehicle and could result inengine damage, transmission damage,structural damage, loss of vehiclecontrol, vehicle rollover and personalinjury.
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
Note: See Recommended TowingWeights (page 310).
Your vehicle may have electrical items,such as fuses or relays, related totowing. See Fuses (page 342).
Your vehicle's load capacity designationis by weight, not by volume, so youcannot necessarily use all availablespace when loading a vehicle or trailer.
Towing a trailer places an extra load onyour vehicle's engine, transmission, axle,brakes, tires and suspension. Inspectthese components periodically during,and after, any towing operation.
Load Placement
To help minimize how trailer movementaffects your vehicle when driving:
•Load the heaviest items closest tothe trailer floor.
•Load the heaviest items centeredbetween the left and right side trailertires.
•Load the heaviest items above thetrailer axles or just slightly forwardtoward the trailer tongue. Do notallow the final trailer tongue weightto go above or below 10-15% of theloaded trailer weight.
•Select a ball mount with the correctrise or drop and load capacity. Whenboth the loaded vehicle and trailerare connected, the trailer frameshould be level, or slightly angleddown toward your vehicle, whenviewed from the side.
When driving with a trailer or payload, aslight takeoff vibration or shudder maybe present due to the increased payloadweight. Additional information regardingproper trailer loading and setting yourvehicle up for towing is located inanother chapter of this manual. SeeLoad Limit (page 293).

RECOMMENDED TOWING
WEIGHTS
Note:Do not exceed the trailer weightfor your vehicle configuration listed inthe chart below.
Note:Make sure to take intoconsideration trailer frontal area. Do notexceed 36.5 feet² (3.39 meters²) if yourvehicle is equipped with the standardtowing package, or 60 feet² (5.57meters²) if your vehicle is equipped withthe optional heavy duty package.
Note:Exceeding this limitation maysignificantly reduce the performance ofyour towing vehicle. Selecting a trailerwith a low aerodynamic drag androunded front design helps optimizeperformance and fuel economy.
Note:For high altitude operation,reduce the gross combined weight by2% per 1,000 ft (300 m) starting at the1,000 ft (300 m) elevation point.
Note:Certain states require electrictrailer brakes for trailers over a specifiedweight. Be sure to check stateregulations for this specified weight. Themaximum trailer weights listed may belimited to this specified weight, as thevehicle’s electrical system may notinclude the wiring connector needed to
activate electric trailer brakes.
Your vehicle may tow a trailer providedthe maximum trailer weight is less thanor equal to the maximum trailer weightlisted for your vehicle configuration onthe following chart.
To calculate the maximum loaded trailerweight for your vehicle:
1.Start with the gross combined weightrating for your vehicle model andaxle ratio. See the following chart.
2.Subtract all of the following that
apply to your vehicle:
•Vehicle curb weight
•Hitch hardware weight, such as adraw bar, ball, locks or weightdistributing
•Driver weight
•Passenger(s) weight
•Payload, cargo and luggageweight
•Aftermarket equipment weight.
3. This equals the maximum loadedtrailer weight for this combination.
Note:The trailer tongue load figuresinto the payload for your vehicle.Reduce the total payload by the finaltrailer tongue weight.

If the trailer safety chain hook has a latch,make sure the latch fully closes.
Trailer Brakes (If Equipped)
WARNING: Do not connect a trailer'shydraulic brake system directly to yourvehicle's brake system. Your vehicle maynot have enough braking power and yourchances of having a collision greatlyincrease.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if you installthem properly and adjust them to themanufacturer's specifications. The trailerbrakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Separate functioning brake systems arerequired for safe control of towed vehiclesand trailers weighing more than 1500 lb(680 kg) when loaded.
Integrated Trailer Brake Controller (If
Equipped)
WARNING: Use the integrated trailerbrake controller to properly adjust thetrailer brakes and check all connectionsbefore towing a trailer. Failure to followthis instruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
When used properly, the trailer brakecontroller assists in smooth and effectivetrailer braking by powering the trailer’selectric or electric-over-hydraulic brakes witha proportional output based on the towingvehicle’s brake pressure.
The controller user interface consists of thefollowing:
A: + and - (Gain adjustment buttons): Pressingthese buttons adjusts the controller's poweroutput to the trailer brakes in 0.5 increments.You can increase the gain setting to 10.0(maximum trailer braking) or decrease it to0 (no trailer braking). The gain settingdisplays in the message center.

Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing-
TowingE265060 E183395

The controller shows gain setting, output bargraph, and trailer connectivity status in theinformation display. They appear in theinformation display as follows:
•Trailer Brake Controller Gain (withouttrailer connected): Shows the current gainsetting during a given ignition cycle andwhen adjusting the gain. This alsodisplays if you use the manual controllever or make gain adjustments with notrailer connected.
•Trailer Brake Controller Gain Output:Displays when you push your vehicle'sbrake pedal, or upon use of the manualcontrol. Bar indicators illuminate in theinformation display to indicate theamount of power going to the trailerbrakes relative to the brake pedal ormanual control input. One bar indicatesthe least amount of output; six barsindicate maximum output.
•Trailer Connected: Displays when thesystem senses a correct trailer wiringconnection (a trailer with electric trailerbrakes) during a given ignition cycle.
•Trailer Disconnected: Displays,accompanied by a single audible time,when the system senses a trailerconnection and then a disconnection,either intentional or unintentional, duringa given ignition cycle. It also displays if atruck or trailer-wiring fault occurs causingthe trailer to appear disconnected. Thismessage can also display if you use themanual control lever without a trailerconnected. After disconnecting the trailerconnector, press the brake pedal forapproximately five seconds to allow thesystem to detect and update the trailerstatus.
B: Manual control lever: Slide the controllever to the left to turn on the trailer's electricbrakes independent of the tow vehicle's. Seethe following Procedure for adjusting gainsection for instructions on proper use of thisfeature. If you use the manual control whilethe brake is also applied, the greater of thetwo inputs determines the power sent to thetrailer brakes.
•Stop lamps: Using the manual controllever illuminates both the trailer brakelamps and your vehicle brake lampsexcept the center high-mount stop lamp,if you make the proper electricalconnection to the trailer. Pressing yourvehicle brake pedal also illuminates bothtrailer and vehicle brake lamps.
Procedure for Adjusting Gain
Note:Only perform this procedure in atraffic-free environment at speeds ofapproximately 20–25 mph (32–40 km/h).
