There should be a setting for the HUD display content under "Settings". Sometimes you have to search through many of the menus to find the right one. I had to look around a bit to figure out how to turn off the wrench icon. It illuminates when the tire rotation interval is approaching (5000 miles), dealer maintenance is due, and oil change is due. I set the oil change to remind me when the oil needs changing based upon time, distance, and driving habits (instead of just mileage) and shut off the other two.
