If I leave the headlights on, and open the door, I do not get a beep indication of the lights on, as in all of my other cars. I have manual 42026, and can not seem to find any resolution on this issue.

Does anyone have any ideas on how to resolve this issue?

I am getting tired of having to jump the car(and recharge the battery) every time the lights get left on!

Thank you,

Hi gedinfo,

Yes, it seems like there should be some a warning tone when the lights are left on, the key is removed and the door is opened; double-check your owners manual just to be sure. I'm looking in the factory service manual and I can't find any reference to it, but I think that function would be handled by the multiplex control unit, which is part of the interior fuse/relay box. Problems with the multiplex control unit can set a trouble code, which can be read with a professional-grade scan tool.
