The system may exhaust (lower vehicle height) for up to 10 minutes after the ignition key has been turned to LOCK. You may hear the air compressor operating when the height is being adjusted. If a weight-distributing hitch is being used, it is recommended to allow the shocks to inflate, thereby leveling the vehicle prior to adjusting the height. See "Weight distributing Hitches and Weight Carrying Hitches" under Towing a Trailer on page 4-53. Recreational Vehicle Towing Recreational vehicle towing means towing your vehicle behind another vehicle - such as behind a motorhome. The two most common types of recreational vehicle towing are known as "dinghy towing" (towing your vehicle with all four wheels on the ground) and "dolly towing" (towing your vehicle with two wheels on the ground and two wheels up on a device known as a "dolly"). Towing Towing Your Vehicle Consult your dealer or a professional towing service if you need to have your disabled vehicle towed. See Roadside Service on page 7-5. If you want to tow your vehicle behind another vehicle for recreational purposes (such as behind a motorhome), see Recreational Vehicle Towing following. Dinghy Towing and Dolly Towing All-Wheel Drive Vehicles Notice: Towing an all-wheel-drive vehicle with all four wheels on the ground, or even with only two of its wheels on the ground, will damage drivetrain components. Do not tow an all-wheel-drive vehicle if any of its wheels will be on the ground. Your vehicle is not designed to be towed with any of the wheels on the ground. If your vehicle must be towed, see Towing Your Vehicle on page 4-52. 4-52
