•Go into the trailer menu, selecttrailer options, select change trailersetting and then select the changesticker option. Your savedmeasurements will be displayed.Do not change them but continueto confirm measurements. Onceyou confirm the measurements, thesystem will then prompt you toperform the calibration procedure.
Note:The system is designed to be usedwith the same trailer connection every timethe trailer is chosen from the selectionmenu. Using a different drawbar or adifferent pin hole (on drawbars with morethan one) when connecting the drawbar toyour vehicle will affect the trailermeasurements. Take the measurementsagain and update if required.
TRAILER SWAY CONTROL (If
Equipped)
WARNING
Turning off trailer sway controlincreases the risk of loss of vehiclecontrol, serious injury or death. Forddoes not recommend disabling this featureexcept in situations where speed reductionmay be detrimental (such as hill climbing),the driver has significant trailer towingexperience, and can control trailer swayand maintain safe operation.
Note:This feature does not prevent trailersway, but reduces it once it begins.
Note:This feature cannot stop all trailersfrom swaying.
Note:In some cases, if vehicle speed is toohigh, the system may activate multipletimes, gradually reducing vehicle speed.
This feature applies your vehicle brakes atindividual wheels and, if necessary, reducesengine power. If the trailer begins to sway,the stability control light flashes and themessage TRAILER SWAY REDUCESPEED appears in the information display.The first thing to do is slow your vehicledown, then pull safely to the side of theroad and check for proper tongue load andtrailer load distribution. See LoadCarrying (page 261).

Note:Exceeding this limitationmay significantly reduce theperformance of your towingvehicle. Selecting a trailer with alow aerodynamic drag and roundedfront design helps optimizeperformance and fuel economy.
Note:For high altitude operation,reduce the gross combined weightby 2% per 1000 feet (300 meters)starting at the 1000 foot (300meter) elevation point.
Note:Certain states requireelectric trailer brakes for trailersover a specified weight. Be sure tocheck state regulations for thisspecified weight. The maximumtrailer weights listed may be limitedto this specified weight, as yourvehicle's electrical system may notinclude the wiring connectorneeded to use electric trailerbrakes.
Your vehicle may tow a trailerprovided the maximum trailerweight is less than or equal to themaximum trailer weightcalculated using the formulafollowing the chart.

ESSENTIAL TOWING CHECKS
WARNING
Do not exceed the maximumpermissible nose weight, e.g. verticalweight on the tow ball. Failure toadhere to this warning could result in lossof vehicle control, serious personal injuryor death.
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive yourvehicle at least 1,000 mi (1,600 km).
•Consult your local motor vehicle lawsfor towing a trailer.
•See the instructions included withtowing accessories for the properinstallation and adjustmentspecifications.
•Service your vehicle more frequently ifyou tow a trailer. See your scheduledmaintenance information.
•If you use a rental trailer, follow theinstructions the rental agency givesyou.
See Load limits in the Load Carryingchapter for load specification terms foundon the tire label and Safety Compliancelabel and instructions on calculating yourvehicle's load.
Vehicles with a diesel engine have anengine braking feature. See GeneralInformation (page 221).
Remember to account for the trailertongue weight as part of your vehicle loadwhen calculating the total vehicle weight.
Some vehicles will have the ability tomodify trailer towing features. SeeGeneral Information (page 111).

If this message displays, with no trailerconnected, the problem is with your vehiclewiring or trailer brake controller. Contactan authorized dealer.
If the message only displays with a trailerconnected, the problem is with the trailerwiring. Consult your trailer dealer forassistance. This can be a short to ground(such as a chaffed wire), short to voltage(such as a pulled pin on trailer emergencybreakaway battery) or the trailer brakesmay be drawing too much current.
Points to Remember
Note:Do not attempt removal of the trailerbrake controller without consulting theWorkshop Manual. Damage to the unit mayresult.
•Adjust gain setting before using thetrailer brake controller.
•Adjust gain setting, using the procedureabove, whenever road, weather, traileror vehicle loading conditions changefrom when the gain was initially set.
•Only use the manual control lever forproper adjustment of the gain duringtrailer setup. Misuse, such asapplication during trailer sway, couldcause instability of trailer or towvehicle.
•Avoid towing in adverse weatherconditions. The trailer brake controllerdoes not provide anti-lock control ofthe trailer wheels. Trailer wheels canlock up on slippery surfaces, resultingin reduced stability of trailer and towvehicle.
•The trailer brake controller is equippedwith a feature that reduces output atvehicle speeds below 11 mph (18 km/h)so trailer and vehicle braking is not jerkyor harsh. This feature is only activewhen applying the brakes using yourvehicle's brake pedal, not thecontroller.
•The controller interacts with the brakecontrol system and powertrain controlsystem of your vehicle to provide thebest performance on different roadconditions.
•Your vehicle's brake system and thetrailer brake system workindependently of each other. Changingthe gain setting on the controller doesnot affect the operation of yourvehicle's brakes.
•When you switch the engine off, thecontroller output is disabled and thedisplay and module shut down.
Trailer Lamps
WARNING
Never connect any trailer lamp wiringto the vehicle's tail lamp wiring; thismay damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.
Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.

Towing

When Towing a Trailer
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•When stopped in congested or heavytraffic during hot weather, place thegearshift in position P to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•If your vehicle is equipped withAdaptive Steering and you haveenabled Tow/Haul, the AdaptiveSteering system adjusts the steeringresponse to match your vehicle’s load.The system reduces vehicle sensitivityto steering inputs at higher vehiclespeeds while it maintains the ease ofparking and maneuverability at lowspeeds.
•If your vehicle is equipped withAdvanceTrac with RSC, this systemmay turn on during typical corneringmaneuvers with a heavily loaded trailer.This is normal. Turning the corner at aslower speed while towing may reducethis tendency.
•If you are towing a trailer frequently inhot weather, hilly conditions, at thegross combined weight rating (or anycombination of these factors), considerrefilling your rear axle with syntheticgear lubricant (if the axle is not alreadyfilled with it).
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1. Turn the steering wheel to point yourvehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission inposition P.
4. Place wheel chocks in front and backof the trailer wheels. (Chocks notincluded with vehicle.)
Your vehicle may be equipped with atemporary or conventional spare tire. A"temporary" spare tire is different in size(diameter or width), tread-type(All-Season or All Terrain) or is from adifferent manufacturer than the road tireson your vehicle. Consult information on thetire label or Safety Compliance label forlimitations when using.
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter you remove the trailer from the water.
