It is recommended to use this system as follows: • For superior ride comfort in an unloaded vehicle the button should be out. The indicator light will not be lit. This button position indicates NORMAL levels of ride control or damping. • For superior ride comfort when trailering, fully loaded, driving off-road, or when personal preferences demand more control, the button should be pressed in with the indicator light lit. This switch position indicates FIRM levels of ride control or damping. The following guide can also be used to help determine the best setting. NORMAL: The indicator light will not be lit when the system is in this setting. Use for normal city and highway driving. This setting provides a smooth, soft ride when the vehicle is unloaded. FIRM (Unloaded): Press the button to activate this setting, the indicator light will be lit. Use this setting when road conditions or personal preference demand more control. This setting provides more "feel" or response to the road conditions. FIRM (Loaded): Press the button to activate this setting, the indicator light will be lit. Use this setting to minimize trailer inputs to the vehicle or when the vehicle is fully loaded. This setting is also appropriate for off-road driving. You can select a setting at any time based on road and trailering conditions to provide the best ride and handling. Select a new setting whenever driving conditions change. Locking Rear Axle If your vehicle has this feature, your locking rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, this feature will allow the wheel with traction to move the vehicle. 360
