System and method for operating an active suspension system of a vehicle includes actuating a switch on the vehicle, setting the active suspension system for the vehicle to a demonstration mode, setting a timer when the active suspension system is set to the demonstration mode, and setting the active suspension system for the vehicle to a normal operating mode after the timer reaches a predetermined time. Prior to expiration of the timer, the system and method determines a gear in which the vehicle is placed, determines whether an engine of the vehicle is running if the transmission gear of the vehicle is drive, reverse, or neutral, and determines a throttle angle of the vehicle if the engine is running. The active suspension system is set to a normal operating mode if the throttle angle is greater than a predetermined angle. An iterative process determines the status of the timer.
