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.

The vehicle aerodynamics are designed to improve fuel economy performance. This may result in a pulsing sound when a window is partially open. To reduce the sound, open another window or the sunroof (if equipped).
