through an unlocked door
when you slow down or stop
your vehicle. Locking your
doors can help prevent this
from happening.
There are several ways to lock and

{WARNING
It is extremely dangerous to ride
on the tailgate, even when the

you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from

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).
Power Windows

could be seriously injured or killed
if caught in the path of a closing
window. Do not leave keys in a
vehicle with children.
When there are children in the
rear seat use the window lockout
button to prevent unintentional
operation of the windows.
