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 may have the optional content
theft-deterrent alarm system.
With this system, a light on the radio will ash.
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 light on
the radio should come on and stay on. If you
are using the remote keyless entry transmitter, the
door does not need to be open.
3. Close all doors. The light on the radio will slowly
ash once the system is armed.Once armed, the alarm will go off if someone tries to
enter the vehicle (without using the remote keyless entry
transmitter or a key) or turns the ignition on with an
incorrect key. The horn will sound and the headlamps
and back-up lamps will ash for approximately two
minutes.
When the alarm is armed, the trunk may be opened with
the remote keyless entry transmitter. If you use the key to
open the trunk, the alarm will sound. The power door lock
switches are also disabled. You must use your remote
keyless entry transmitter or your key to unlock the doors
when the system is armed.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
lock switch to lock the doors while any door or the
trunk is open and the key is removed from the ignition.
The light on the radio ashes quickly to let you know
when the system is ready to arm with the power
door lock switches. The light on the radio will stop
ashing and stay on when you press the bottom of the
power lock switch, to let you know the system is
arming. After all doors and the trunk are closed and
locked, the light on the radio will ash slowly to let you
know the system is armed.
2-15

Arming with the Remote Keyless Entry
Transmitter
Your alarm system will arm when you use your remote
keyless entry transmitter to lock the doors, if the key
is not in the ignition. The light on the radio will turn on to
let you know the system is arming. After all doors and
the trunk are closed and locked, the light on the
radio will begin ashing at a very slow rate to let you
know the system is armed.
Disarming with the Remote Keyless
Entry Transmitter
Your alarm system will disarm when you use your
remote keyless entry transmitter to unlock the doors.
The light on the radio will go off to let you know
the system is no longer armed.
The rst time a remote UNLOCK command is received,
three ashes will be seen and three horn chirps heard to
indicate an alarm condition has occurred since last
arming.
Disarming with Your Key
Your alarm system will disarm when you use your key
to unlock the doors. The light on the radio will go
off to let you know the system is no longer armed.
Passlock®
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, fuel is disabled and
the engine will not start.
During normal operation, the SECURITY message will
be displayed after the key is turned to the ON ignition
position. SeeSecurity Message on page 3-49.
If the engine stalls and the SECURITY message
ashes, wait until the light stops ashing before trying to
restart the engine.
If the engine is running and the SECURITY message
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.
SeeFuses and Circuit Breakers on page 5-103. See your
dealer for service.
In an emergency, contact Chevrolet Roadside
Assistance. SeeRoadside Assistance Program on
page 7-6for more information.

ACC (ACCESSORY):This is the position in which you
can operate your electrical accessories. With the key
in this position, the ignition and automatic transaxle will
unlock.
ON:This is the position to which the switch returns after
you start the engine and release the switch. The switch
stays in ON while the engine is running. But even when
the engine is not running, you can use ON to operate
your electrical accessories and to display some
instrument panel cluster messages and warning lights.
START:This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.
While the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the radio.
A warning chime will sound if you open the driver’s door
while the ignition is in OFF or ACC and the key is in
the ignition.
Retained Accessory Power (RAP)
With Retained Accessory Power (RAP), your power
windows, audio system and sunroof (option) will
continue to work for up to 10 minutes after the ignition is
turned to OFF and none of the doors is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position — that’s a
safety feature. To restart when you’re already moving,
use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Starting Your 3400 V6 Engine
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as
your engine warms up.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If the engine doesn’t start in 10 seconds, push the
accelerator pedal about one-quarter of the way down
while you turn the key to START. Do this until the
engine starts. As soon as it does, let go of the key.

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).
2-39

6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.
7. Firmly press and release the “Learn” or “Smart”
button. The name and color of the button may
vary by manufacturer.
You will have 30 seconds to start Step 8.
8. Return to the vehicle. Firmly press and hold the
programmed HomeLink
®button for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
®should now activate your rolling-code
equipped device.
To program the remaining two HomeLink
®buttons,
begin with Step 2 of “Programming HomeLink®.” Do not
repeat Step 1.
Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to “time out” or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
“time out” in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
“Programming HomeLink
®” procedures (regardless of
where you live), replace Step 3 under “Programming
HomeLink
®” with the following:
Continue to press and hold the HomeLink
®button while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink
®. The
indicator light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming HomeLink
®”
to complete.
