2012 engine immobilizer light flashes normal ?

in the middle of my trip to florida, i have noticed the engine immobilizer system light (center console, car icon with key inside) flashes after i shut the engine off, remove key and leave the vehicle. first time its done this.........the manual is useless. I tried disconnecting the battery, didn't fix the issue . This can't be right, can it? If so, why didn't i ever see the light previously? my main concern is that i will have a dead battery soon.

 

its normal dont worry about it. mine does it too

 

ok, i've heard that, thanks.......hopefully i'll make it to florida and not stranded at this campground in selma, nc.........LOL, jking..........much appreciated, still weird to me that i've owned the vehicle for 20 months and never noticed it before.
