Security light blinks 4 times, pauses, and repeats

Hi everyone, we just picked up our new 2007 B9 Tribeca Limited 7 passenger. We like the car so far. We noticed that the security light that is to the right of the nav screen blinks 4 times, pauses, and repeats continuously. This happens if the car is in park or if we are scooting down the highway at 70mph. I can't find any mention of this in the owners manual. I suspect something is busted. Has anyone else seen this?

Thanks!

Louis
