456 STARTING AND OPERATING OFF-ROAD DRIVING TIPS NOTE: Prior to off-road driving, remove the front air dam to prevent damage. The front air dam is attached to the lower front fascia with seven quarter turn fasteners and can be removed by hand. Quadra-Lift™ - If Equipped When off-roading, it is recommended that the lowest useable vehicle height that will clear the current obstacle or terrain be selected. The vehicle height should then be raised as required by the changes in terrain. The Selec-Terrain™ switch will automatically change the vehicle to the optimized height based on the SelecTerrain™ switch position. The vehicle height can be changed from the default height for each Selec-Terrain™ mode by normal use of the air suspension switches. Refer to "Quadra-Lift™ - If Equipped" in "Starting and Operating" for further information. When To Use 4WD LOW Range - If Equipped When off-road driving, shift to 4WD LOW for additional traction. This range should be limited to extreme situations such as deep snow, mud, or sand where additional low speed pulling power is needed. Vehicle speeds in excess of 25 mph (40 km/h) should be avoided when in 4WD LOW range. Front Air Dam 1 - Front Bumper 2 - Front Air Dam Fasteners
