I always remote start my Traverse on cold mornings, just a couple minutes ahead of time to get the oil circulating, heated seats automatically warm up too! *LOL* Never thought I would think that is such a cool feature but love it. Its is true in the summer I could put the AC on full blast before turning off the car in the evening so next morning when I remote start it will turn on but heat doesnt bother me, love it.
Its impossible to steal the car with Chevy remote start, the doors are locked, the shifter and steering is locked and no other functions of the vehicle will work, NONE, including the dashboard until the key is inserted and turned.
