Quick question: I have both a 2008 CX-7 GT AWD and a 2008 CX-9 GT AWD. On the CX-9, the lights stay ON (if they were "on" while the engine was running) for about 20 seconds or so after I turn off the engine, I'm guessing this is for safety and as a courtesy while you walk away from the vehicle. However, on the CX-7 the lights turn off immediately when I shut off the engine. Is this the way the CX-7 lights are supposed to work? I figure it is a very similar lighting system on both trucks, so why the difference? (Both are equipped with the "Auto" lights setting). Can someone enlighten me please? Thank you!
