To drive without use of the right leg, the Electronic Left-Foot Accelerator is installed to the left of the brake pedal. Each time the vehicle is started, a green-lighted button on the dashboard flashes for 10 seconds. If, while flashing, the driver pushes the button, the left-foot accelerator pedal is activated and the original one de-activated. If the button is not pushed, the original accelerated pedal remains operational (for a driver who uses the right foot). Both pedals are never active at the same time.
