Automatic Level Control This feature keeps the rear of your vehicle level as the load changes. It is automatic, you do not need to adjust anything. This type of level control is fully automatic and will provide a better leveled riding position as well as better handling under a variety of passenger and loading conditions. An air compressor connected to the rear shocks will raise or lower the rear of the vehicle to maintain proper vehicle height. The system is activated when the ignition key is turned to RUN and will automatically adjust vehicle height thereafter. The system may exhaust (lower vehicle height) for up to ten minutes after the ignition key has been turned to OFF. You may also hear the air compressor operating when the height is being adjusted. 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"). With the proper preparation and equipment, many vehicles can be towed in these ways. See "Dinghy Towing" and "Dolly Towing," following. Here are some important things to consider before you do recreational vehicle towing: • What is the towing capacity of the towing vehicle? Be sure you read the tow vehicle manufacturer's recommendations. Towing Towing Your Vehicle Consult your dealer or a professional towing service if you need to have your disabled vehicle towed. See Roadside Assistance Program on page 7-6. If you want to tow your vehicle behind another vehicle for recreational purposes (such as behind a motorhome), see "Recreational Vehicle Towing" following. 4-34 • How far will you tow? Some vehicles have restrictions on how far and how long they can tow. • Do you have the proper towing equipment? See your dealer or trailering professional for additional advice and equipment recommendations. • Is your vehicle ready to be towed? Just as you would prepare your vehicle for a long trip, you will want to make sure your vehicle is prepared to be towed. See Before Leaving on a Long Trip on page 4-21.
