STARTING AND OPERATING 367 • Park Mode (Lowers the vehicle approximately 1.5 in (38 mm) - This position lowers the vehicle for easier passenger entry and exit as well as lowering the rear of the vehicle for easier loading and unloading of cargo. To enter Park Mode, press the "Down" button once while the vehicle speed is below 25 mph (40 km/h). Once the vehicle speed goes below 15 mph (24 km/h) the vehicle height will begin to lower. If the vehicle speed remains between 15 mph (24 km/h) and 25 mph (40 km/h) for greater than 60 seconds, or the vehicle speed exceeds 25 mph (40 km/h) the Park Mode change will be cancelled. To exit Park Mode, press the "Up" button once while in Park Mode or drive the vehicle over 15 mph (24 km/h). The Selec-Terrain™ switch will automatically change the vehicle to the proper height based on the position of the Selec-Terrain™ switch. The height can be changed from the default Selec-Terrain™ setting by normal use of the air suspension buttons. Refer to "Selec-Terrain™" in "Starting and Operating" for further information. 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. 5
