Found this on our 2013 Cayenne Hybrid, next to the driver's seat door side.

 

Thats the internal motion sensor disable. If you are going to lock the car with kids/pets use that to disable the sensor so the alarm doesn't go off.

I don't recall mine having the light or icon on it, but I haven't looked at it too closely.

 

Thanks! I was wondering what that thing was for! I kept pressing it expecting some magic to happen, haha

 

LOL, thanks! That makes sense!

 

Time to study manual.
