Driving and Operating 247The trailer tongue (1) should weigh10 to 15 percent of the total loadedtrailer weight (2).After loading the trailer, weigh thetrailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.Total Weight on Your Vehicle'sTiresBe sure the vehicle's tires areinflated to the upper limit for coldtires. These numbers can be foundon the Tire and Loading Informationlabel. See Vehicle Load Limits0 189. Make sure not to go over theGVW limit for the vehicle, includingthe weight of the trailer tongue.Trailer Towing (SedanV6 and V-Series)The vehicle is neither designed norintended to tow a trailer.Towing Equipment(Sedan With L4 Engine)HitchesUse the correct hitch equipment.See your dealer or a hitch dealer forassistance.. The rear bumper on the vehicleis not intended for hitches. Donot attach rental hitches or otherbumper-type hitches to it. Useonly a frame-mounted hitch thatdoes not attach to the bumper.. Will any holes be made in thebody of the vehicle when thetrailer hitch is installed? If so,seal the holes when the hitch isremoved. If the holes are notsealed, dirt, water, and deadlycarbon monoxide (CO) from theexhaust can get into the vehicle.See Engine Exhaust 0 199.Safety ChainsAlways attach chains between thevehicle and the trailer. Cross thesafety chains under the tongue ofthe trailer to help prevent the tonguefrom contacting the road if itbecomes separated from the hitch.Leave enough slack so the rig canturn. Never allow safety chains todrag on the ground.Trailer BrakesDoes the trailer have its ownbrakes? Be sure to read and followthe instructions for the trailer brakesso they are installed, adjusted, andmaintained properly.Because the vehicle has antilockbrakes, do not tap into the vehicle'sbrake system.
