The window can also be operated using the global
window buttons. See “Global Window Feature”
previously.
{CAUTION:
If express override is activated, the midgate
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 midgate window path.
Midgate Window Express Override Mode
If an obstruction or weather condition such as severe
icing stops the window as it is moving upward, the
window will automatically reverse to a partially open
position. The window will return to normal operation
once the obstruction or condition is removed.
The window auto-reversal function can be overridden in
the express override mode. To override, the window
must be operated manually by pressing and holding the
midgate window switch or the global window button.
This must be done within two seconds after the midgate
window has stopped at a partially open position. The
express override mode only works immediately following
a window auto-reversal. Window express functions
will not work while in this mode.
Midgate Window Error/Jog Mode
If the midgate window has sensed conditions which may
lead to damage or malfunction of the window system,
the window will automatically go into Error/Jog mode. In
this mode, window express functions will not work.
The window can only be operated manually by pressing

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light in the
instrument panel cluster will
ash as you open the door
if your ignition is off.
This light reminds you to activate the theft-deterrent
system. Here is how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light will illuminate to inform the driver the system is
arming. If a door is open when the doors are
locked, the security light will ash.
2-21

3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes off.
If the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the delay
timer has expired. SeeDelayed Locking on
page 2-9.
If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. The
headlamps and parking lamps will ash for two minutes,
and the horn will sound for 30 seconds, then will turn
off to save the battery power. You can choose different
feedback options for the alarm. SeeDIC Vehicle
Customization on page 3-55.
Remember, the theft-deterrent system will not activate if
you lock the doors with the vehicle’s key or use the
manual door lock. It activates only if you use a power
door lock switch with the door open, or with the remote
keyless entry transmitter. You should also remember
that you can start your vehicle with the correct ignition
key if the alarm has been set off.Here is how to avoid setting off the alarm by accident:
If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the
door keyafterthe doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm.
If you set off the alarm by accident, unlock any door with
the key. You can also turn off the alarm by pressing
unlock on the remote keyless entry transmitter. The alarm
will not stop if you try to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
2-22

While the alarm is set, the power door unlock switch is
not operational.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works. The
horn fuse may be blown. To replace the fuse, see
Instrument Panel Fuse Block on page 5-116and
Underhood Fuse Block on page 5-119.
If the alarm does not sound or the headlamps do not
ash, the vehicle should be serviced by your dealer.
Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, the fuel system is
disabled and the vehicle will not start.During normal operation, the security light will turn off
approximately ve seconds after the key is turned
to RUN.
If the engine stalls and the security light ashes, wait
about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release
the key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®at this
time. You may also want to check the fuse. See
Instrument Panel Fuse Block on page 5-116and
Underhood Fuse Block on page 5-119. See your dealer
for service.
In an emergency, call the Roadside Assistance Center.
SeeRoadside Assistance Program on page 7-6.

The transfer case is a part of the Full-Time Four-Wheel
Drive system and allows the following four different
modes of operation:
4
m(Full-Time Four-Wheel Drive):This setting is
used for driving in most street and highway situations.
You can also use this setting for light or variable
off-road conditions.
4
mQ(Four-Wheel-High Lock):Use this mode
when you need extra traction in most off-road situations
such as sand, mud, snow, or level, rocky trails.
4
nQ(Four-Wheel-Low Lock):This mode delivers
extra torque to all four wheels and is used for extreme
off-road conditions. You might choose
Four-Wheel-Low Lock if you are driving off-road in deep
sand, mud, or snow and climbing or descending
steep hills.
When in this mode you can also choose to lock the rear
axle for additional traction in extreme off-road situations.
SeeLocking Rear Axle on page 4-10.Notice:Operating your vehicle in
Four-Wheel-Low Lock above 50 mph (80 km/h) for
any extended period of time could cause damage to
the transfer case. Do not operate your vehicle in
Four-Wheel-Low Lock above 50 mph (80 km/h) for
extended periods.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
