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 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).
