disarming the security system completely

[mikeocd]

After reading the Manual several times I realize the alarm sytem is very complicated. The last thing I want is it to go off at an RV park, and I dont know how to shut it off. I will use the key to lock the door. Question is I don't see a fuse or circuit marked Security system. Does anyone know how to dis-arm it completely, there is a red light and a toggle switch under the steering wheel, the light is on and the switch is down?? 2004 M380..
