Hi I have just bought a 2012 IX35 2.0 Crdi premium. I take my dog with me in the car an very occassionally need to leave him in it to nip into a shop for 10 mins. Is there an internal alarm which would activeate? I always leave windows and the sun roof open for him to get air, I haven't played with it yet but the other day I tried to loack the car with windows open and it wouldn't let me? advise would be appreciated.
