twice or the lock button on the RKE
transmitter twice will override the
delayed locking feature and
immediately lock all the doors.
This feature will not operate if the
key is in the ignition.
This feature can be programmed by

(DIC). See“DELAY DOOR LOCK”
under Vehicle Personalization (With
DIC Buttons) on page 5‑44.
Automatic Door Locks
Vehicles with an automatic lock/
unlock feature enable you to
program the vehicle's power door
locks. This feature can be
programmed through the Driver
Information Center (DIC). See
Vehicle Personalization (With DIC
Buttons)
on page 5‑44for more

locking the key in the vehicle when
the key is in the ignition and a front
door is open.
If the driver side power door lock
switch is pressed when the driver's
door is open and the key is in the
ignition, all of the doors will lock and
then the driver door will unlock.

the key is in the ignition, all of the
doors will lock and then the front
passenger door will unlock.
Safety Locks

security locks on the inside edge of
each door.
To set the locks, insert a key into
the slot and turn it to the horizontal

Vehicle Security
Vehicle theft is big business,
especially in some cities. This
vehicle has theft-deterrent features,
however, they do not make it
impossible to steal.
Anti-Theft Alarm System
On vehicles with an anti-theft alarm
system, to activate the system:
.PressQon the Remote Keyless
Entry (RKE) transmitter or the
power door lock switch when
any door is open.
The security light flashes.
When the door is closed, the
security light stops flashing and
stays on solid for approximately 30 seconds. The content theft
deterrent alarm is not armed
until the security light goes off.
If the delayed locking feature is
active, the alarm is not activated
until all doors are closed and the
security light goes off.
.PressQwhen the driver door is
closed. The security light comes
on solid for approximately
30 seconds and then goes off.
The content theft deterrent alarm
is not armed until the security
light goes off.
The theft-deterrent system will not
activate if the doors are locked with
the vehicle's key or the manual
door lock.
If a locked door is opened without
using the RKE transmitter, a ten
second pre-alarm occurs. The horn
chirps and the lights flash. If the key
is not placed in the ignition and
turned to START or the door is not
unlocked by pressing
Qduring the
ten second pre-alarm, the alarm goes off. The headlamps flash
and the horn sounds for about
30 seconds, then turns off to save
the battery power.
The vehicle can be started with the
correct ignition key if the alarm has
been set off.
To avoid setting off the alarm by
accident:
.Lock the vehicle with the door
key after the doors are closed.
.Unlock the door with the RKE
transmitter. Unlocking a door any
other way sets off the alarm if
the system has been armed.
Press
Kor place the key in the
ignition and turn it to START to turn
off the alarm.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower the driver side window and open
the driver door.
2. Press
Q.

2-14 Keys, Doors and Windows
3. Get out of the vehicle, close thedoor 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.
If the alarm does not sound when it
should, but the vehicle's 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 10‑31.
If the alarm does not sound or the
vehicle's headlamps do not flash,
see your dealer/retailer for service.
Immobilizer
See Radio Frequency Statementon
page 13‑16for information regarding
Part 15 of the Federal
Communications Commission (FCC)
Rules and RSS-210/211 of Industry
and Science Canada.
Immobilizer Operation
This vehicle has PASS-Key®III+
(Personalized Automotive Security
System) theft-deterrent system.
PASS-Key
®III+ is a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned to
ON/RUN, ACC/ACCESSORY or
START from the LOCK/OFF
position.
You do not have to manually arm or
disarm the system.
The security light comes on if there
is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key
®III+ system
senses an incorrect key, the vehicle
does not start. Anyone using a
trial-and-error method to start the vehicle will be discouraged because
of the high number of electrical key
codes.
If the engine does not start and the
security light on the instrument
panel comes on when trying to start
the vehicle, there may be a problem
with your theft-deterrent system.
Turn the ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key and check
the fuses. See
Fuses and Circuit
Breakers
on page 10‑31for
additional information. If the engine
still does not start with the other key,
the vehicle needs service. If the
vehicle does start, the first key may
be faulty. See your dealer/retailer
who can service the PASS-Key
®III+
to have a new key made. In an
emergency, contact Roadside
Assistance. See Roadside
Assistance Program on page 13‑5.
It is possible for the PASS-Key
®III+
decoder to learn the transponder
value of a new or replacement key.

Keys, Doors and Windows 2-15
Up to 10 keys may be programmed
to the vehicle. The following
procedure is for programming
additional keys only. If all the
currently programmed keys are lost
or do not operate, you must see
your dealer/retailer or a locksmith
who can service PASS-Key
®III+ to
have keys made and programmed
to the system.
See your dealer/retailer or a
locksmith who can service
PASS-Key
®III+ to get a new key
blank that is cut exactly as the
ignition key that operates the
system. To program the new additional key:
1. Verify that the new key has a
1
stamped on it.
2. Insert the already programmed key in the ignition and start the
engine. If the engine does not
start, see your dealer/retailer for
service.
3. After the engine has started, turn the key to LOCK/OFF, and
remove the key.
4. Insert the key to be programmed and turn it to the ON/RUN
position within five seconds of
the original key being turned to
the LOCK/OFF position.
The security light turns off once
the key has been programmed. 5. Repeat Steps 1 through 4 if
additional keys are to be
programmed.
If the PASS-Key®III+ key is lost or
damaged, see your dealer/retailer or
a locksmith to have a new
key made.
The SERVICE THEFT
DETERRENT SYSTEM message
displays on the Driver Information
Center (DIC) when there is a
problem with the theft-deterrent
system. See Anti-Theft Alarm
System Messages
on page 5‑40for additional information.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
