sound, open either a front window
or the sunroof, if equipped.

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.

If any object is in the path of the
window when the express-up is
active, the window will stop at the

also cause the window to
auto-reverse. The window will return
to normal operation once the
obstruction or condition is removed.
