218 UNDERSTANDING THE FEATURES OF YOUR VEHICLE LOAD-LEVELING SYSTEM - IF EQUIPPED The automatic load-leveling system will provide a level riding vehicle under most passenger and cargo loading conditions. A hydraulic pump contained within the shock absorbers raises the rear of the vehicle to the correct height. It takes approximately 1 mile (1.6 km) of driving for the leveling to complete depending on road surface conditions. If the leveled vehicle is not moved for approximately 15 hours, the leveling system will bleed itself down. The vehicle must be driven to reset the system. WARNING! Do not install the load-leveling system on vehicles that are not equipped with Anti-Lock Brakes. Vehicles without Anti-Lock Brakes (ABS) have a heightsensing proportioning valve. Installing a leveling system will render this system ineffective, inappropriately reducing rear brake pressure, resulting in increased stopping distances. You could have a serious accident.
