Here is the link to power gear leveling, it states that with the lights you have blinknig there is a "panel comunication error", in a compartment outside, look up, screwed to bottom side of floor, there should be a black box says power gear on it aprox 3"x5" and aprox 1" thick , make sure plugs are clean and making good contact, also check plug at back of panel on dash.
