I just bought a 2005 with 66,000 miles and flawless interior and exterior. I have read the owners manual and cannot find a reference to a lighted toggle button to the right of the headlight switch. This button has a led that illuminates when the engine is running and if you depress the upper side of the button a beeping sound can be heard from the dash close to the radio. I can't find any reference to it in the manual that I downloaded from the web. Maybe that manual is covering a different model, but any tips would be appreciated.
