Your battery is probably bad, the minimum reading should be 12v. Try charging it to see if it comes up to at least 12v and preferably 13.6v when the battery charger is removed. If it doesn't then one cell in the battery has gone bad. As for the steps, they should retract when the engine is started, but have no effect on the starting of the vehicle.
