Driving and Operating Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way. Notice: Overloading the vehicle may cause damage. Repairs would not be covered by the vehicle warranty. Do not overload the vehicle. If you put things inside your vehicle - like suitcases, tools, packages, or anything else - they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going. 9-27 { WARNING Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. . There is also important loading information for off-road driving in this manual. See "Loading Your Vehicle for Off-Road Driving" under Off-Road Driving on page 9‑7. Remember not to exceed the Gross Axle Weight rating (GAWR) of the front or rear axle. Two-Tiered Loading For vehicles with a six foot bed, an upper load platform can be created by positioning four 5 cm (2 inches) by 15 cm (6 inches) wooden planks across the width of the pickup box. The planks must be inserted in the pickup box depressions. When using this upper load platform, be sure the load is securely tied down to prevent it from shifting. The load's center of gravity should be positioned in a zone over the rear axle. Put things in the cargo area of your vehicle. Try to spread the weight evenly. Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. Do not leave an unsecured child restraint in your vehicle. When you carry something inside the vehicle, secure it whenever you can. Do not leave a seat folded down unless you need to. . . . .
