Spring-loaded SET/DECEL button engages cruise. During engagement, if SET/DECEL button is pressed and held, vehicle decelerates (cruise disengages) until button is released. When button is released, cruise engages and maintains new set speed. Also, by quickly pressing and releasing (tapping) this button, the set speed is "tapped" down in one MPH increments.
