Calculating the MaximumLoaded Trailer Weight for YourVehicle
1. Start with the gross combinedweight rating for your vehiclemodel and axle ratio. See theprevious chart.
2.Subtract all of the followingthat apply to your vehicle:
•Vehicle curb weight
•Hitch hardware weight, such asa draw bar, ball, locks or weightdistributing hardware
•Driver weight
•Passenger(s) weight
•Payload, cargo and luggageweight
•Aftermarket equipment weight.
This equals the maximum loadedtrailer weight for this combination.
Note:The trailer tongue load isconsidered part of the payload foryour vehicle. Reduce the totalpayload by the final trailer tongueweight.
Note:Consult an authorized dealerto determine the maximum trailer
weight allowed for your vehicle ifyou are not sure.
ESSENTIAL TOWING CHECKS
Follow these guidelines for safetowing:
•Do not tow a trailer until youdrive your vehicle at least 1000miles (1600 kilometers).
•Consult your local motorvehicle laws for towing a trailer.
•See the instructions includedwith towing accessories for theproper installation andadjustment specifications.

Do not use a hitch that eitherclamps onto the bumper orattaches to the axle. You mustdistribute the load in your trailerso that 10-15% for conventionaltowing or 15-25% for fifth wheeltowing of the total weight of thetrailer is on the tongue.
Weight-distributing Hitches
WARNING
Do not adjust aweight-distributing hitch toany position where the rearbumper of the vehicle is higherthan it was before attaching thetrailer. Doing so will defeat thefunction of the weight-distributinghitch, which may causeunpredictable handling, and could
result in serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, alwaysuse the following procedure:
1. Park the loaded vehicle,without the trailer, on a levelsurface.
2.Measure the height to the topof your vehicle's front wheelopening on the fender. This isH1.
3.Attach the loaded trailer toyour vehicle without theweight-distributing barsconnected.
4.Measure the height to the topof your vehicle's front wheelopening on the fender a secondtime. This is H2.
5.Install and adjust the tensionin the weight-distributing barsso that the height of yourvehicle's front wheel openingon the fender is approximatelyhalfway between H1 and H2.
6.Check that the trailer is level orslightly nose down toward yourvehicle. If not, adjust the ballheight accordingly and repeatSteps 2-6.
Once the trailer is level or slightlynose down toward the vehicle:
•Lock the bar tension adjusterin place.
•Check that the trailer tonguesecurely attaches and locksonto the hitch.
•Install safety chains, lighting,and trailer brake controls asrequired by law or the trailermanufacturer.

Procedure for Adjusting Gain
Note:Only perform this procedurein a traffic-free environment atspeeds of approximately 20-25mph (30-40 km/h).
The gain setting sets the trailerbrake controller for the specifictowing condition. You shouldchange the setting as towingconditions change. Changes totowing conditions include trailerload, vehicle load, road conditionsand weather.
The gain should be set to providethe maximum trailer brakingassistance while making sure thetrailer wheels do not lock whenusing the brakes. Locked trailerwheels may lead to trailerinstability.
1.Make sure the trailer brakes arein good working condition,functioning normally andproperly adjusted. See yourtrailer dealer if necessary.
2.Hook up the trailer and makethe electrical connectionsaccording to the trailermanufacturer's instructions.
3.When you plug in a trailer withelectric orelectric-over-hydraulic brakes,TRAILER CONNECTEDappears in the informationdisplay.
4.Use the gain adjustment (+ and-) buttons to increase ordecrease the gain setting to thedesired starting point. A gainsetting of 6.0 is a good startingpoint for heavier loads.
5.In a traffic-free environment,tow the trailer on a dry, levelsurface at a speed of 20-25mph (30-40 km/h) andsqueeze the manual controllever completely.
6.If the trailer wheels lock up,indicated by squealing tires,reduce the gain setting. If thetrailer wheels turn freely,

Initial Output Setting
The trailer brake controller letsyou customize how aggressivelythe trailer brakes engage. Thedefault value is set to “Light”. Werecommend this setting for themajority of trailers. If you are usingan EOH trailer with a high settingvoltage, or if you prefer to feelmore brake feedback from thetrailer, then select “Medium” or“Heavy”.
Trailer Brake Effort Setting
The trailer brake controller allowsthe user to customize howaggressively the trailer brakesengage. The default value is "Low"and is the recommended settingfor most trailers. If your trailer'sbrakes require more initial voltage,or if you prefer more aggressivetrailer braking, then select eitherthe "Medium" or the "High"setting.

If the message only displays witha trailer connected, the problemis with the trailer wiring. Consultyour trailer dealer for assistance.This can be a short to ground(such as a chaffed wire), short tovoltage (such as a pulled pin ontrailer emergency breakawaybattery) or the trailer brakes maybe drawing too much current.
Points to Remember
Note:Do not attempt removal ofthe trailer brake controller withoutconsulting the Workshop Manual.Damage to the unit may result.
•Adjust gain setting before usingthe trailer brake controller forthe first time.
•Adjust gain setting, using theprocedure above, wheneverroad, weather and trailer orvehicle loading conditionschange from when the gainwas initially set.
•Only use the manual controllever for proper adjustment ofthe gain during trailer setup.Misuse, such as applicationduring trailer sway, could causeinstability of trailer or towvehicle.
•Avoid towing in adverseweather conditions. The trailerbrake controller does notprovide anti-lock control of thetrailer wheels. Trailer wheelscan lock up on slipperysurfaces, resulting in reducedstability of trailer and towvehicle.
•The trailer brake controller isequipped with a feature thatreduces output at vehiclespeeds below 11 mph (18 km/h)so trailer and vehicle braking isnot jerky or harsh. This featureis only available when applyingthe brakes using your vehicle'sbrake pedal, not the controller.
•The controller interacts withthe brake control system andpowertrain control system ofyour vehicle to provide the bestperformance on different roadconditions.
•Your vehicle's brake systemand the trailer brake systemwork independently of eachother. Changing the gainsetting on the controller doesnot affect the operation of yourvehicle's brakes whether youattach a trailer or not.
