Programmable Automatic
Door Locks
Your vehicle is equipped with an automatic locklunlock
feature which enables you
to program your vehicle’s
power door locks. You can program this feature through
the Driver Information Center (DIC), or by the following
method.
Programmable Locking Feature
The following is the list of available programming
options:
Mode 1: All doors lock when the transmission is shifted
into gear.
Mode 2: All doors lock when the vehicle speed is
greater than 8 mph (13 km/h).
Mode 3: No automatic door locking.
The automatic door locks were pre-programmed at the
factory to lock all the doors when the transmission
is shifted into gear. The following instructions detail how
to program your door locks differently than the factory
setting. Choose one of the three programming
options listed above before entering the program mode.
To enter the program mode, do the following:

Lockout Protection
This feature protects you from locking your key in the
vehicle when the key is in the ignition and a door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all
of the doors will
lock and then the driver’s door will unlock.
Liftgate/Liftglass
It can be dangerous to drive with the liftgab- or
liftglass open because carbon monoxide (CO)
gas can come into your vehicle. You can’t see
or smell CO.
It can cause unconsciousness
and even death. If you must drive with the
liftgate open or
if electrical wiring or other
cable connections must pass through the seal
between the body and the liftgate or liftglass:
Make sure all other windows are shut.

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 flash as you open
the door
if your ignition
is
off.
This light reminds you to activate the theft-deterrent
system. Here’s 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 should come
on and stay on.
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 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 flash 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. See Driver lnformation
Center
(DIC) on page 3-43.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a 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’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the 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
won’t stop
if you try to unlock a door any other way.

Testing the Alarm Passlock@’
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.
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 flash, check
to see if the horn works. The
horn fuse may be blown. To replace the fuse, see Fuses
and Circuit Breakers on page
5-87.
If the alarm does not sound or the headlamps do not
flash, the vehicle should be serviced by your dealer. 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 five seconds after the key is turned
to RUN.
If the engine stalls and the security light flashes, wait
about
10 minutes until the light stops flashing 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 Fuses and Circuit
Breakers
on page 5-87. See your dealer for service.
In an emergency, call the Roadside Assistance Center.
See Roadside Assistance Program
on page 7-5.
