3. Close all doors. The security light should go
off after about 30 seconds. The alarm is not
armed until the security light goes off.
If the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the
delay timer has expired. SeeDelayed Locking
on page 103.
The content theft deterrent system does not
sense if the midgate is open or ajar, therefore,
vehicle contents may not be protected if the
midgate is left open or ajar.
If a locked door is opened without the key or the
RKE transmitter, a ten second pre-alarm will occur.
The horn will chirp and the lights will ash. If the
door is not unlocked using the key or by pressing
the unlock button on the RKE transmitter during
the ten second pre-alarm, 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. You can choose different feedback options
for the alarm. SeeDIC Vehicle Customization
(With DIC Buttons) on page 278.Remember, the theft-deterrent system will not
activate if you lock the doors with the vehicle’s key
or use the manual door lock. It activates only if
you use a power door lock switch while the door is
open, or when you use 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.
Here is how 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 keyafterthe doors
are closed.
Always unlock a door with a key, or use the
RKE 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 RKE transmitter.
The alarm will not stop if you try to unlock a
door any other way.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the driver’s
side of the engine compartment, near
the power steering uid reservoir.
3. Plug the cord into a normal, grounded
110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. 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.How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.
Active Fuel Management™
Your vehicle’s V8 engine 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 your 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.
Your vehicle has an Active Fuel Management™
indicator. For more information on using this
display seeDIC Operation and Displays (With
DIC Buttons) on page 258orDIC Operation and
Displays (Without DIC Buttons) on page 264.

{CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to
roll, even if your shift lever is in PARK (P).
So, be sure the transfer case is in a drive
gear — not in NEUTRAL. Always set your
parking brake.
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 139.
If you are pulling a trailer, seeTowing a Trailer
on page 414.
Mirrors
Automatic Dimming Rearview Mirror
with OnStar
®, Compass and
Temperature Display
Your vehicle may have this feature. When on, the
automatic dimming mirror dims to the proper level
to minimize glare from lights behind you after dark.
The mirror has a dual display in the upper right
corner of the mirror face that shows the compass
reading and the outside temperature.
Control buttons for the OnStar
®system, if
equipped, are at the bottom of the mirror.
SeeOnStar

Not all services are available everywhere,
particularly in remote or enclosed areas, or
at all times.
OnStar
®service that involves location information
about your vehicle cannot work unless GPS
satellite signals are unobstructed and available
in that place as well.
Your vehicle must have a working electrical
system (including adequate battery power) for
the OnStar
®equipment to operate. There are
other problems OnStar®cannot control that may
prevent OnStar®from providing OnStar®service
to you at any particular time or place. Some
examples are damage to important parts of your
vehicle in an accident, hills, tall buildings, tunnels,
weather or wireless phone network congestion.
Your Responsibility
You may need to increase the volume of your
radio to hear the OnStar®advisor. If the light next
to the OnStar®buttons is red, this means that
your system is not functioning properly and should
be checked by a dealer. If the light appears
clear (no light is appearing), your OnStar

subscription has expired. You can always press
the OnStar®button to con rm that your OnStar®
equipment is active.
