Never leave a child, a helpless
adult, or a pet alone in a vehicle,
especially with the windows

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.
