2-18 Keys, Doors and Windows Vehicles with OnStar have three additional control buttons for the OnStar system. See your dealer for more information about OnStar and how to subscribe to it. See the OnStar Owner Guide for more information about the services OnStar provides. Windows { WARNING Leaving children, helpless adults, or pets in a vehicle with the windows closed is dangerous. They can be overcome by the extreme heat and suffer permanent injuries or even death from heat stroke. Never leave a child, a helpless adult, or a pet alone in a vehicle, especially with the windows closed in warm or hot weather. Cleaning the Mirror Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water. The vehicle aerodynamics are designed to improve fuel economy performance. This may result in a pulsing sound when either rear window is down and the front windows are up. To reduce the sound, open either a front window or the sunroof (if equipped).
