That little light comes on when it wants and I cannot figure out how to shut it off. It kills the battery. This is not good in the sub zero winter temps. I have read about the security system which I never use but it has no mention of this light. Car has key less entry and remote start but even with new battery's they do not work. Does the light have something to do with that or another purpose? I just want to disable it. Car is out in the country with no real danger of being stolen. This is on a 07 Endeavor. Any ideas?
