STARTING AND OPERATING 449 The system requires that the engine be running for all changes. When lowering the vehicle all of the doors, including the liftgate, must be closed. If a door is opened at any time while the vehicle is lowering the change will not be completed until the open door(s) is closed. The Quadra-Lift™ air suspension system uses a lifting and lowering pattern which keeps the headlights from incorrectly shining into oncoming traffic. When raising the vehicle, the rear of the vehicle will move up first and then the front. When lowering the vehicle, the front will move down first and then the rear. After the engine is turned off, it may be noticed that the air suspension system operates briefly, this is normal. The system is correcting the position of the vehicle to ensure a proper appearance. To assist with changing a spare tire, the Quadra-Lift™ air suspension system has a feature which allows the automatic leveling to be disabled. Refer to "Uconnect® Settings" in "Understanding Your Instrument Panel" for further information. NOTE: If equipped with a touch screen radio all enabling/disabling of air suspension features must be done through the radio. Refer to "Uconnect® Access Settings" in "Understanding Your Instrument Panel" for further information. 5 WARNING! The air suspension system uses a high pressure volume of air to operate the system. To avoid personal injury or damage to the system, see your authorized dealer for service.
