Driving TRACTION-LOK AXLE (IF EQUIPPED) This axle provides added traction on slippery surfaces, particularly when one wheel is on a poor traction surface. Under normal conditions, the Traction-Lok axle functions like a standard rear axle. Extended use of other than the manufacturer's specified size tires on a Traction-Lok rear axle could result in a permanent reduction in effectiveness. This loss of effectiveness does not affect normal driving and should not be noticeable to the driver. To avoid injury, never run the engine with one wheel off the ground, such as when changing a tire. VEHICLE LOADING Before loading a vehicle, familiarize yourself with the following terms: • Base Curb Weight : Weight of the vehicle including any standard equipment, fluids, lubricants, etc. It does not include passengers or aftermarket equipment. • Payload : Combined maximum allowable weight of cargo, passengers and optional equipment.

The GVW is not a limit or a specification. • GVWR (Gross Vehicle Weight Rating) : Maximum total weight of the base vehicle, passengers, optional equipment and cargo. The GVWR is specific to each vehicle and is listed on the Safety Compliance Label on the driver's door pillar. • GAWR (Gross Axle Weight Rating) : Carrying capacity for each axle system.
