• Normal Ride Height (NRH) – This is the standard position of the suspension and is meant for normal driving.

• Off-Road 1 (OR1) (Raises the vehicle approximately 1.3 in (33 mm) – This position should be the default position for all off-road driving until OR2 is needed. A smoother and more comfortable ride will result. Press the “Up” button once from the NRH position while the vehicle speed is below 38 mph (61 km/h). When in the OR1 position, if the vehicle speed remains between 40 mph (64 km/h) and 50 mph (80 km/h) for greater than 20 seconds or if the vehicle speed exceeds 50 mph (80 km/h), the vehicle will be automatically lowered to NRH. Refer to “Off-Road Driving Tips” in “Starting and Operating” for further information.

• Off-Road 2 (OR2) (Raises the vehicle approximately 2.6 in (65 mm) – This position is intended for offroading use only where maximum ground clearance is required. To enter OR2, press the “Up” button twice from the NRH position or once from the OR1 position while vehicle speed is below 20 mph (32 km/h). While in OR2, if the vehicle speed exceeds 25 mph (40 km/h) the vehicle height will be automatically lowered to OR1. Refer to “Off-Road Driving Tips” in “Starting and Operating” for further information.

• Aero Mode (Lowers the vehicle approximately 0.5 in (13 mm) – This position provides improved aerodynamics by lowering the vehicle. The vehicle will automatically enter Aero Mode when the vehicle speed remains between 62 mph (99 km/h) and 66 mph (106 km/h) for greater than 20 seconds or if the vehicle speed exceeds 66 mph (106 km/h). The vehicle will return to NRH from Aero Mode if the vehicle speed remains between 30 mph (48 km/h) and 35 mph (56 km/h) for greater than 20 seconds or if the vehicle speed falls below 30 mph (48 km/h). The vehicle will enter Aero Mode, regardless of vehicle speed if the • Normal Ride Height (NRH) – This is the standard position of the suspension and is meant for normal driving.

The vehicle will enter Aero Mode, regardless of vehicle speed if the 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. 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. Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information. Driving the vehicle over 5 mph (8 km/h) will return the air suspension to normal operation. Refer to “Jacking and Tire Changing” in “What To Do In Emergencies” for further information.

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.
