Power Windows
{ CAUTION:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome from extreme heat in
warm or hot weather and suffer permanent
injuries or even death from heat stroke.
Leaving children in a vehicle with the ignition
key is dangerous for many reasons, children
or others could be badly injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
The windows will function with the keys in the
ignition and they 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.
If your vehicle has power windows, the controls are
located on each of the side doors in the front and rear
for crew cab and extended cab models.
The driver’s door has a switch for the passenger’s and
rear windows as well. Your power windows will work
when the ignition has been turned to ACCESSORY or
RUN or when Retained Accessory Power (RAP) is
active. See Retained Accessory Power (RAP) on
page 2-23.
Press the switch down to lower the window, and pull up
the front of the switch to raise the window.
