Hi, I just bought a Cube SL with impact sensors a few days ago and just noticed the security indicator light flashing every 3 seconds when the car is off. Is it normal for that light to keep flashing? It does turn off when the car is on. The security indicator light is the one shaped like a car with a key inside. (Sorry if this is a stupid question. Just paranoid. :-[ Oh, and I don't have the intelligent key system).
