Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however, they
do not make it impossible to steal.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent alarm
system.
This is the security light.To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE) transmitter. The security light should come
on and flash.
If the delayed locking feature is active, the alarm
will not be activated until all doors are closed and
the security light goes off.
3. Close all doors. The security light will stop flashing and go off after approximately 30 seconds. The
content theft deterrent alarm is not armed until the
security light goes off.
If a locked driver door is opened without using the RKE
transmitter, a ten second pre-alarm will occur. The horn
will chirp and the lights will flash. If the key is not placed
in the ignition and turned to START or the door is not
unlocked by pressing the unlock button on the RKE
transmitter during the ten second pre-alarm, the alarm
will go off. Your vehicle's headlamps will flash and the
horn will sound for about 30 seconds, then will turn off
to save the battery power.
3-17

The theft-deterrent system will not activate if the doors
are locked with the vehicle's key or the manual door
lock. It activates only if you use the power door lock
switch with the door open or the RKE transmitter. You
should also remember that you can start your vehicle
with the correct ignition key if the alarm has been
set off.
To avoid setting off the alarm by accident:
.If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
.Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if the system has been armed.
If you set off the alarm by accident, press unlock on the
RKE transmitter or place the key in the ignition and turn
it to START to turn it off.
Testing the Alarm
To test the alarm: 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 RKE 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.
If the alarm does not sound when it should but the
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 6‑118.
If the alarm does not sound or the headlamps do not
flash, see your dealer for service.

PASS-Key®III+ Electronic
Immobilizer
See Radio Frequency Statementon page 8‑18for
information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry Canada.
PASS-Key®III+ Electronic
Immobilizer Operation
Your 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 will come on if there is a problem with
arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. 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 cluster 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. At this time,
you may also want to check the fuse, see Fuses and
Circuit Breakers
on page 6‑118. If the engine still does
not start with the other key, your vehicle needs service.
3-19

If your vehicle does start, the first key may be faulty.
See your dealer who can service the PASS-Key®III+ to
have a new key made. In an emergency, contact
Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to learn
the transponder value of a new or replacement key. Up
to 10 keys may be programmed for 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 or a locksmith
who can service PASS-Key
®III+ to have keys made
and programmed to the system.
See your dealer 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
1stamped on it.
2. Insert the original, already programmed, key in the ignition and start the engine. If the engine will not
start, see your dealer for service.
3. After the engine has started, turn the key to LOCK/ OFF, and remove the key.
4. Insert the new key to be programmed and turn it to the ON/RUN position within five seconds of turning
the ignition to the LOCK/OFF position in Step 3.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys are to be programmed.
If you lose or damage your PASS-Key
®III+ key, see
your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. Thecord is secured to the Engine Compartment Fuse
Block with a clip. Carefully remove the wire tie
which bundles the electrical plug. Do not cut the
electrical cord.
3. Plug the cord into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from
moving engine parts. If you do not, it could be
damaged. The length of time the heater should remain plugged in
depends on several factors. Ask a dealer in the area
where you will be parking the vehicle for the best advice
on this.
Active Fuel Management™
Vehicles with V8 engines may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders, depending
on the driving conditions.
When less power is required, such as cruising at a
constant vehicle speed, the system will operate in the
half cylinder mode, allowing the vehicle to achieve
better fuel economy. When greater power demands are
required, such as accelerating from a stop, passing,
or merging onto a freeway, the system will maintain
full-cylinder operation.
If the vehicle has an Active Fuel Management™
indicator, see
DIC Operation and Displays (With DIC
Buttons)
on page 4‑49or DIC Operation and Displays
(Without DIC Buttons)on page 4‑56for more
information on using this display.

System
SeeRadio Frequency Statementon page 8‑18for
information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry Canada.
Universal Home Remote System
Operation (With Three Round LED)
This vehicle may have the Universal Home Remote
System. If there are three round Light Emitting Diode
(LED) indicator lights above the Universal Home
Remote buttons, follow the instructions below.
This system provides a way to replace up to three
remote control transmitters used to activate devices
such as garage door openers, security systems, and
home automation devices. Do not use this system 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.
Read the instructions completely before attempting to
program the transmitter. Because of the steps involved,
it may be helpful to have another person assist with
programming the transmitter.
Be sure to keep the original remote control transmitter
for use in other vehicles, as well as, for future
programming. Only the original remote control
transmitter is needed for Fixed Code programming. The
programmed buttons should be erased when the
vehicle is sold or the lease ends. See
“Erasing
Universal Home Remote Buttons” later in this section.
Park the vehicle outside of the garage when
programming a garage door. Be sure that people and
objects are clear of the garage door or gate that is
being programmed.

Roof Rack System
{WARNING:
If something is carried on top of the vehicle that is
longer or wider than the roof rack—like paneling,
plywood, or a mattress— the wind can catch it
while the vehicle is being driven. The item being
carried could be violently torn off, and this could
cause a collision, and damage the vehicle. Never
carry something longer or wider than the roof rack
on top of the vehicle unless using a GM Certified
accessory carrier. For vehicles with a roof rack, the rack can be used to
load items. For roof racks that do not have crossrails
included, GM Certified crossrails can be purchased as
an accessory. See your dealer for additional
information.
Notice:
Loading cargo on the roof rack that weighs
more than 91 kg (200 lbs) or hangs over the rear or
sides of the vehicle may damage the vehicle. Load
cargo so that it rests evenly between the crossrails,
making sure to fasten cargo securely.
To prevent damage or loss of cargo when driving, check
to make sure crossrails and cargo are securely
fastened. Loading cargo on the roof rack will make the
vehicle’s center of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may result in loss of control.
If driving for a long distance, on rough roads, or at high
speeds, occasionally stop the vehicle to make sure the
cargo remains in its place.
