Rear Door Security Locks
Your vehicle may have this feature. You can lock the
rear doors so they can’t be opened from the inside
by passengers. To use one of these locks do the
following:
1. Open one of the rear doors. You will nd a
security lock lever located on the inside edge
of each rear door.
2. Move the lever down to
engage the safety lock.
Move the lever up to
disengage the
safety lock.
3. Close the door.The rear doors of your vehicle cannot be opened from
the inside while this feature is in use. If you want to open
the rear door while the security lock is on, unlock the
door and open the door from the outside.
Lockout Protection
This feature stops the power door locks from locking
when the key is in the ignition and a door is open
to protect you from locking your key in the vehicle.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock
and then the driver’s door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, take your key, open your
door and set the lock from inside. Then get out and
close the door.

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. However, there are ways you
can help.
Content Theft-Deterrent
Your vehicle may be equipped with a content
theft-deterrent alarm system.
Here’s how to operate the system:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light should ash.
3. Close all doors. The security light should turn off
after approximately 30 seconds. The alarm is not
armed until the security light turns 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 ash for two minutes,
and the horn will sound for 30 seconds, then will turn
off to save the battery power.
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
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
won’t stop if you try to unlock a door any other way. United States
Canada
2-16

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.
When 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, seeFuses
and Circuit Breakers on page 5-93.
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 that
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
Fuses and Circuit Breakers on page 5-93. See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.

Outside Convex Mirror
A convex mirror’s surface is curved so you can see
more from the driver’s seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right or left lane,
you could hit a vehicle. Check your inside
mirror or glance over your shoulder before
changing lanes.
Outside Heated Mirrors
Your vehicle may have this feature.
When you operate the rear window defogger, a defogger
also warms the heated driver’s and passenger’s
outside rearview mirrors to help clear them of ice, snow
and condensation.
OnStar®System
Your vehicle may have this feature. OnStar®uses
global positioning system (GPS) satellite technology,
wireless communications, and state of the art call
centers to provide you with a wide range of safety,
security, information and convenience services.

receiver, provides a way to replace up to three
hand−held transmitters used to activate devices such as
gate operators, garage door openers, entry door
locks, security systems and home lighting. Additional
HomeLink
®information can be found on the internet at
www.homelink.com or by calling 1- 800- 355- 3515.

Programming the HomeLink®
Transmitter
Do not use the HomeLink®Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
2-39

Keep the original transmitter for use in other vehicles as
well as for future HomeLink®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light will ash slowly at rst and then
rapidly after HomeLink
®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
®button
and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink
®button is pressed and
released.
To program the remaining two HomeLink
®buttons,
begin with Step 2 under “Programming HomeLink®.”
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).
