Dinghy Towing Your vehicle was not designed to be towed with all of its wheels on the ground. It can be towed with two of its wheels on the ground. See "Dolly Towing" following. Level Control On vehicles equipped with automatic level control, the rear of the vehicle is automatically kept level as you load or unload your vehicle. However, you should still not exceed the GVWR or the GAWR. See Loading Your Vehicle on page 332. You may hear the compressor operating when you load or unload your vehicle, and periodically as the system self-adjusts. This is normal. The compressor should operate for brief periods of time. If the sound continues for an extended period of time, your vehicle needs service. 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. Dolly Towing To dolly tow your vehicle, do the following: 1. Put the front wheels on a dolly. 2. Put the vehicle in PARK (P). 3. Set the parking brake and then remove the key. 4. Clamp the steering wheel in a straight-ahead position with a clamping device designed for towing. 5. Release the parking brake. 339
