Keyless Access System Operation
Your vehicle has a Keyless Access System that allows
you to lock and unlock your doors, unlock your trunk lid
and disarm or arm your theft-deterrent system. The range
distance is as much as 100 feet (30 m) away.
Your vehicle comes with two transmitters, and up to
four can be matched to your vehicle. See “Matching
Transmitter(s) to Your Vehicle” later in this section.
Q(Lock):Press this button to lock the doors. The
indicator light on the door will ash once. If this button is
pressed twice, the doors will lock, the light will ash
once and the horn will sound once.
K(Unlock):Press this button once to unlock the
driver’s door. The indicator light on the door will ash
twice. Press the button twice within 10 seconds to
unlock both doors. If it is dark enough outside, your
interior lamps will come on.
Your memory settings may also be recalled when
you press the unlock button on the keyless access
transmitter. SeeMemory Seat, Mirrors and Steering
Wheel on page 1-3for more information.
G(Trunk):Press and hold this button for about
one second to open the trunk while the engine is turned
off or the shift lever is in PARK (P).
L(Panic):Press this button to sound the vehicle
alarm. Press any other button on the keyless access
transmitter to stop the vehicle alarm.

Power Door Locks
The power door lock switches are located on the doors.
There is an indicator light on the rear of the door
near the window.
K(Unlock):Press to unlock the doors.
When pressed, a beep sounds. If the door is closed
when pressed, the light ashes twice. If the door is
open when pressed, the light ashes.
Q(Lock):Press to lock the doors.
When pressed, a beep sounds. If the door is closed
when pressed, the light comes on for a few seconds,
then turns off. If the door is open when pressed,
the light stays on.
Automatic Door Lock
Your vehicle is programmed so that, when the doors are
closed, the ignition is on and the shift lever is moved
out of PARK (P), all the doors will lock.
If someone needs to get out while the vehicle is not in
PARK (P), have the person use the power door unlock
switch. When the door is closed again, the doors will lock
either when your foot is removed from the brake or the
vehicle speed becomes faster than 8 mph (13 km/h).
Programmable Automatic
Door Unlock
Your vehicle is programmed so that, when the shift
lever is moved into PARK (P), both doors will unlock.
With the vehicle in PARK (P) and the engine running,
door unlocking can be programmed through prompts
displayed on the Driver Information Center (DIC).
These prompts allow the driver to choose various
unlock settings. For programming information,
seeDIC Vehicle Personalization on page 3-76.
Lockout Protection
Your vehicle can be programmed to sound the horn
three times and unlock the driver’s door when both
doors are closed and there is a keyless access
transmitter inside the vehicle. When the driver’s door
is opened, a reminder chime will sound continuously.
The vehicle will remain locked only when at least
one transmitter has been removed from the vehicle
and both doors are closed. SeeDIC Vehicle
Personalization on page 3-76.
2-12

Arming the System
To arm the system:
Press the lock button on the keyless access
transmitter.
Open the door. Lock the door with the power
door lock switch. The security light should
ash. Remove the keyless access transmitter
from the interior of the vehicle and close the door.
The security light will stop ashing and stay on.
After 30 seconds, the light should turn off.
The vehicle can be programmed to automatically
lock the doors and arm the system when you
exit the vehicle. SeeDIC Vehicle Personalization
on page 3-76.
Now, if a door or the trunk lid is opened without the
keyless access transmitter, the alarm will go off. Your
horn will sound for two minutes, then it will go off to save
battery power. And, your vehicle will not start without
a keyless transmitter present.
The theft-deterrent system will not arm if you lock the
driver’s door with the power door lock switch after
the doors are closed.
If your passenger stays in the vehicle when you leave
with the keyless access transmitter, have the passenger
lock the vehicle after the doors are closed. This way the
alarm will not arm, and your passenger will not set it off.
Testing the Alarm
To test the system:
1. Make sure the trunk lid is latched.
2. Lower the window on the driver’s door.
3. Manually arm the system.
4. Close the doors and wait 30 seconds.
5. Reach through the open window and manually
pull the release lever on the oor.
6. Turn off the alarm by pressing the unlock button
on the transmitter.
If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. SeeFuses and
Circuit Breakers on page 6-90. If the horn works, but
the alarm doesn’t go off, see your dealer/retailer.
Disarming the System
Always use your keyless access transmitter to unlock
a door either by pressing the unlock button on the
transmitter or by squeezing the door handle sensor while
you have the transmitter with you. Unlocking a door any
other way will set off the alarm. If your alarm sounds,
press the unlock button on the keyless access transmitter
to disarm it.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Passive Locking
This feature allows you to select whether the doors
automatically lock during normal vehicle exit. When the
ignition is turned off and all doors become closed,
the vehicle will determine how many keyless access
transmitters remain in the vehicle interior. If at least
one keyless access transmitter has been removed
from the interior of the vehicle, the doors will lock
after eight seconds.
For example, if there are two keyless access
transmitters in the vehicle and one is removed, the
other will be locked in. The keyless access transmitter
locked in the vehicle can still be used to start the vehicle
or unlock the doors, if needed. A person approaching
the outside of the locked vehicle without an authorized
keyless access transmitter, however, will not be able
to open the door, even with a transmitter in the vehicle.
