Programmable Automatic
Door Locks
If your vehicle has an automatic transmission, the
vehicle is programmed so that the doors will lock
automatically when all doors are closed, the ignition
is on, and the shift lever is moved out of PARK (P). The
doors will automatically unlock when you stop the
vehicle and move the shift lever back into PARK (P).
If your vehicle has a manual transmission, the vehicle is
programmed so that the doors will lock automatically
after the vehicle speed reaches 5 mph (8 km). The doors
will automatically unlock when the ignition is turned
off and the key is removed from the ignition.
If someone needs to exit the vehicle once the doors
are locked, have that person use the manual lever
or power door lock switch. When the door is closed
again, it will not lock automatically. Use the manual lever
or the power door lock switch to lock the door.
The power door locks can be programmed through
prompts displayed on the Driver Information
Center (DIC). These prompts allow you to choose
various lock and unlock settings. For more information
on programming, seeDIC Vehicle Personalization
on page 3-70.

Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-37.
Trunk Lock Release
The remote trunk release
button is located on the
lower portion of the
driver’s door.
To use the remote trunk release, the shift lever must be
in PARK (P) or NEUTRAL (N) for a vehicle with an

in NEUTRAL, with the parking brake set for a vehicle
with a manual transmission.
Press the button to open the trunk. You can also press
the button with the trunk symbol on the Remote
Keyless Entry (RKE) transmitter to open the trunk.

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.
Theft-Deterrent System
If your vehicle has this
feature, the security light is
located on the instrument
panel cluster.
If the ignition is off and a door is open, the security light
will ash, reminding you to arm the theft-deterrent
system.
To arm the system, do the following:
1. Lock the door using the Remote Keyless
Entry (RKE) transmitter or the power door
lock switch.
2. Close all the doors. The security light will come on.
It should go off within approximately 30 seconds.
Your security system is now armed.
If a door or a trunk is opened without a key or a RKE
transmitter, the horn will sound and the lamps will ash
for up to 30 seconds.
2-18

The theft-deterrent system will not arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the RKE transmitter or the
power lock on the door.
To avoid activating the alarm by accident do the
following:
Lock the door with the key or the manual door lock
after the doors are closed if you do not want to arm
the theft-deterrent system.
Always unlock a door with a key or use the RKE
transmitter. Pressing the unlock button on the
RKE transmitter disables the theft-deterrent system.
Unlocking a door any other way will activate the
alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm
by using the unlock button on the RKE transmitter, or by
starting the vehicle with a valid key.
Testing the Alarm
1. Roll down the window, then get out of the vehicle,
keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock switch
or the RKE transmitter and close the door. Wait
approximately 30 seconds until the security
light goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the exterior lamps will ash.
The alarm can be turned off by unlocking the driver’s
door with the key, using the unlock button on the
RKE transmitter or by starting the car with a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, seeFuses and Circuit Breakers on
page 5-104. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.
