Keys, Doors, and Windows 2-15 Windows { WARNING Never leave a child, a helpless adult, or a pet alone in a vehicle, especially with the windows closed in warm or hot weather. They can be overcome by the extreme heat and suffer permanent injuries or even death from heat stroke. 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. Power Windows { WARNING Children could be seriously injured or killed if caught in the path of a closing window. Never leave keys in a vehicle with children. When there are children in the rear seat, use the window lockout button to prevent operation of the windows. See Keys on page 2‑1. The switches on the driver door armrest are used to control each of the windows. Each passenger door has its own window switch. The power window switches work while the ignition is in ON/RUN, ACC/ACCESSORY, or while Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 9‑17.
