Express Window Anti-Pinch Feature
If any object is in the path of the window when
the express-up is active, the window will stop at the
obstruction and auto-reverse to a preset factory position.
Weather conditions such as severe icing may also
cause the window to auto-reverse. The window
will return to normal operation once the obstruction or
condition is removed.
Express Window Anti-Pinch Override
{CAUTION:
If express override is activated, the window
will not reverse automatically. You or others
could be injured and the window could be
damaged. Before you use express override,
make sure that all people and obstructions are
clear of the window path.
In an emergency, the anti-pinch feature can be
overridden in a supervised mode. Hold the window
switch all the way up in the express position. The
window will rise for as long as the switch is held. Once
the switch is released, the express mode is re-activated.In this mode, the window can still close on an object in
its path. Use care when using the override mode.

driver’s door armrest near the window switches. Press
this button to disable the rear window controls. The light
on the button will illuminate, indicating that the feature

using the driver’s window switches when the lockout
feature is on. To restore power to the rear windows,
press the button again. The light on the button will
go out.
The front passenger window can be programmed
to be disabled using the window lockout button.

The other vehicle’s lamp(s) cannot be detected due
to dense exhaust, smoke, fog, snow, road spray,
mist or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked or
obstructed by something that blocks the view of the
Intellibeam™ light sensor.
Your vehicle’s windshield is covered with ice, dirt,
haze or other obstructions.
Your vehicle is loaded such that the front end of the
vehicle points upward, causing the Intellibeam™
sensor to aim high and not detect headlamps
and taillamps.
You are driving on winding or hilly roads.
You may need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.

factory setting by using the controls on the inside
rearview mirror.

rearview mirror ashes two times. This lets you
know that Intellibeam™ has been turned off and will not
come back on until the system has been reset.
To reset the system, quickly press and release this
button on the inside rearview mirror. The indicator on the
inside rearview mirror will ash one time to indicate
