@jasonsklo1 Those are interior sensors for the security system. You should have two options that pop up in your instrument cluster after shutting the vehicle off or you can navigate to your vehicle settings for either option. "Perimeter Only" basically monitors exterior intrusion such as a broken window. The other setting, "All Sensors" is for both Exterior and Interior intrusion/movement. The most obvious example I can think of when this setting comes into play....say you leave your windows down, but lock the car. If someone sticks their hand through the open windows or if the sensors detect movement inside of the vehicle, the sensors should set off the alarm. I also believe turning on All Sensors will detect the change in your vehicle inclination such as unwanted towing. Kind of a nice feature.
