OFF-ROAD CAPABILITIES • The Quadra-Lift™ air suspension system uses a lifting and lowering pattern which keeps the headlights from 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, you may notice that the air suspension system operates briefly. This is normal. The system is correcting the position of the vehicle. • To assist with changing a spare tire, the Quadra-Lift™ air suspension system has a feature which allows the automatic leveling to be disabled. Press and hold both the "Up" and "Down" buttons simultaneously between 5 and 10 seconds; a message will appear in the EVIC stating leveling has been disabled immediately after both buttons have been released. Driving the vehicle over 5 mph (8 km/h) will return the air suspension to normal operation. • An audible chime will be heard whenever a system error has been detected. Operation • Pressing the "Up" or "Down" button once will move the suspension one position higher or lower from the current position, assuming all conditions are met (i.e., engine running and all doors and liftgate closed). • The 4 indicator lamps will illuminate to show the current position of the vehicle. Flashing indicator lamps will show a position which the system is working to achieve. If multiple indicator lamps are flashing on the "Up" button, the highest flashing indicator lamp is the position the system is working to achieve. UP • Normal Ride Height (NRH) - This is the standard position of the suspension and is meant for normal driving. Only the bottom Indicator lamp on the "Up" button will be illuminated when the vehicle is in this position. • Off-Road 1 (OR1) (Raises the vehicle approximately 1.3 in (33 mm) - This position is intended for off-road driving only where vehicle speeds may go above 25 mph (40 km/h). Press the "Up" button once from NRH while vehicle speed is below 48 mph (77 km/h). The bottom two Indicator lamps on the "Up" button will be illuminated when the vehicle is in OR1. • Off-Road 2 (OR2) (Raises the vehicle approximately 2.6 in (65 mm) - This position is intended for off-road driving where maximum ground clearance is required. Press the "Up" button twice from NRH, or once from OR1 position while vehicle speed is below 20 mph (32 km/h). All three Indicator lamps on the "Up" button will be illuminated when the vehicle is in OR2. UP UP 88
