Pre-Safe Inoperable warning
I took my 2011 E350 to the dealership to be serviced and when I got it back, the PRE-SAFE INOPERABLE warning came on. Also, when I first crank the car, the radio, back-up camera and gps system all come on but then go off after only a few seconds. Is there some kind of reset button that needs to be switched on/off to remedy this situation?
