SAFETY - Vehicle Loading that Federal Motor Carrier Safety Regulation 392.7 requires a pre-trip inspection and so do commercial trucking companies. You are not expected to become a professional mechanic. The purpose of your inspections is to find anything that might interfere with the safe and efficient transportation of yourself, any passengers, and your load. If you do find something wrong and cannot fix it yourself, have an authorized dealer or qualified mechanic repair your vehicle right away. The following operations are to be performed by the driver. Performing these checks and following the maintenance procedures in this manual will help keep your vehicle running properly.

specifications. (Axle weight ratings are listed on the driver's door edge.) 1 WARNING Do not exceed the specified load rat- ing. Overloading can result in loss of vehicle control, either by causing com- ponent failures or by affecting vehicle handling. Exceeding load ratings can also shorten the service life of the ve- hicle. Failure to comply may result in death or personal injury. GVWR is the Gross Vehicle Weight Rating. This is the MAXIMUM WEIGHT your vehicle is allowed to carry, including the weight of the empty vehicle, loading platform, occupants, fuel, and any load. Never exceed the GVWR of your vehicle.

GCW is the actual combined weight, or Gross Combination Weight (GCW), of your vehicle and its load: vehicle, plus trailer(s), plus cargo. GAWR is the Gross Axle Weight Rating. This is the total weight that one axle is designed to transmit to the ground. You will find this number listed on the driver's door edge. WARNING An unevenly distributed load or exces- sive load over one axle can adversely affect the braking and handling of your vehicle, which could result in an acci- dent. Even if your load is under the le- gal limits, be sure it is distributed even- ly. Failure to comply may result in death, personal injury, equipment or property damage.

Load Distribution be sure any load you carry is distributed so that no axle has to support more than its GAWR. Vehicle Loading Be sure that the load on the vehicle is distributed evenly across each axle so that no axle has to support more than its rated GAWR. In total, the vehicle and its load should not exceed the GAWR for each axle and must not exceed the GCW Compare your vehicle's load capacity with the total load you are carrying. If adjustments need to be made, make them, do not drive an overloaded vehicle. If you are overloaded or your load has shifted, your vehicle may be unsafe to drive.

The Gross Vehicle Weight Rating (GVWR) or the maximum front and rear Gross Axle Weight Ratings are determined by the components installed from the factory on to the vehicle and their designed Y53-6047-2HEN (03/18) 35
