The gross vehicle weight is the sum of weights of the unloaded vehicle, driver, passengers, luggage, hitch and trailer tongue load. It also includes the weight of any special equipment installed on your vehicle. D The load on either the front or rear axle resulting from distribution of the gross vehicle weight on both axles must not exceed the front and rear Gross Axle Weight Ratings (GAWR) listed on the Certification Label. D Trailer hitch assemblies have different weight capacities established by the hitch manufacturer. Even though the vehicle may be physically capable of towing a higher weight, the operator must determine the maximum weight rating of the particular hitch assembly and never exceed the maximum weight rating specified for the trailer-hitch. Exceeding the maximum weight rating set by the trailer hitch manufacturer can cause an accident resulting in serious personal injuries. 2003 4RUNNER from Oct. '02 Prod. (OM35804U) 263
