Black plate (70,1)Cadillac SRX Owner Manual - 2013 - CRC - 11/9/129-70 Driving and OperatingIf a weight-carrying hitch or aweight-distributing hitch is beingused, the trailer tongue (1) shouldweigh 10-15 percent of the totalloaded trailer 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.Trailering may be limited by thevehicle's ability to carry tongueweight. Tongue weight cannot causethe vehicle to exceed the GVWR(Gross Vehicle Weight Rating) orthe RGAWR (Rear Gross AxleWeight Rating). The effect ofadditional weight may reduce thetrailering capacity more than thetotal of the additional weight.It is important that the vehicledoes not exceed any of itsratings — GCWR, GVWR, RGAWR,Maximum Trailer Rating or TongueWeight. The only way to be sure it isnot exceeding any of these ratingsis to weigh the vehicle and trailer.Total Weight on the Vehicle'sTiresBe sure the vehicle's tires areinflated to the upper limit for coldtires. These numbers can be foundon the Certification label or seeVehicle Load Limits on page 9‑10.Make sure not to go over the GVWlimit for the vehicle, or the GAWR,including the weight of the trailertongue. If using a weight distributinghitch, make sure not to go over therear axle limit before applying theweight distribution spring bars.Towing EquipmentHitchesIt is important to have the correcthitch equipment. Crosswinds, largetrucks going by and rough roads area few reasons why the right hitch isneeded.. 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 thereare, then be sure to seal theholes later 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 onpage 9‑22.
