Not sure how many of us are aware of this feature, but I was impressed. Pulled into my favorite watering hole, rolled the windows down (sign of my age), set the alarm and began to hydrate. After a few minutes or beers, which ever came first, I remembered I left my cellphone in the cup holder and went to retrieve it. To my surprise the alarm went off. I did not open any doors, jult leaned in and retrieved my cellphone from the cup holder. There is obviously a motion detector in the system for the cabin area.
