4,203 lb. (1906 kg) - 4,103 lb. (1861 kg) = 100 lb. (45 kg) GVWR GVW Available for tongue weight Capacity available for towing Always verify that available capacities are within the required ratings. WARNING Trailer hitch components have specific weight ratings. Your vehicle may be capable of towing a trailer heavier than the weight rating of the hitch components. Never exceed the weight rating of the hitch components. Doing so can cause serious personal injury or property damage. TOWING LOAD/SPECIFICATION TOWING LOAD / SPECIFICATION UNIT: lb (kg) MAXIMUM TOWING LOAD MAXIMUM TONGUE LOAD 1,000 lb. (454 kg) 1,000 (454) 100 (45) 100 lb. (45 kg) Available tongue weight / 1,000 lb. (454 kg) = Available capacity 10 % tongue weight Hitch ball Choose a hitch ball of the proper size and weight rating for your trailer: ● The required hitch ball size is stamped on most trailer couplers. Most hitch balls also have the size printed on the top of the ball. ● Choose the proper class hitch ball based on the trailer weight. ● The diameter of the threaded shank of the hitch ball must be matched to the ball mount hole diameter. The hitch ball shank should be no more than 1/16" smaller than the hole in the ball mount. TOWING SAFETY Trailer hitch Choose a proper hitch for your vehicle and trailer. Make sure the trailer hitch is securely attached to the vehicle, to help avoid personal injury or property damage due to sway caused by crosswinds, rough road surfaces or passing trucks. The available towing capacity may be less than the maximum towing capacity due to the passenger and cargo load in the vehicle. Remember to keep trailer tongue weight between 10 - 15% of the trailer weight or within the trailer tongue load specification recommended by the trailer manufacturer. If the tongue load becomes excessive, rearrange the cargo to obtain the proper tongue load. Do not exceed the maximum tongue weight specification shown in the "Towing load/specification" chart even if the calculated available tongue weight is greater than 15%. If the calculated tongue weight is less than 10% , reduce the total trailer weight to match the available tongue weight. Technical and consumer information 9-19
