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 270orDIC Operation and
Displays (Without DIC Buttons) on page 277.
Automatic Transmission Operation
If your vehicle is has an automatic transmission,
it has an electronic shift position indicator
within the instrument panel cluster. This display
comes on when the ignition key is turned to
the RUN position.There are several different positions for the shift
lever.
See “Range Selection Mode” later in this section.
PARK (P):This position locks your rear wheels. It
is the best position to use when you start the engine
because your vehicle cannot move easily.

Range Selection Mode (Allison®or
Hydra-Matic®6-Speed Transmission)
Your vehicle may have a Range Selection Mode.
The Range Selection Mode helps control the
vehicle’s transmission and vehicle speed while
driving down hill or towing a trailer by letting
you select a desired range of gears.To use this feature, do the following:
1. Move the shift lever to the MANUAL
MODE (M).
2. Press the plus/minus buttons, located on the
steering column shift lever, to select the
desired range of gears for your current driving
conditions.
When MANUAL MODE (M) is selected a number
displays next to the M, indicating the current gear.
This number is the highest gear that can be used.
However, your vehicle can automatically shift to
lower gears as it adjusts to driving conditions. This
means that all gears below that number are
available. When FIFTH (5) is selected, FIRST (1)
through FIFTH (5) gears are automatically shifted
by the vehicle, but SIXTH (6) cannot be used until
the plus/minus button located on the steering
column lever is used to change to the gear.

{CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to
roll, even if the shift lever is in PARK (P).
So, be sure the transfer case is in a drive
gear — not in NEUTRAL. Always set the
parking brake.
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 165.
If you are pulling a trailer, seeTowing a Trailer on
page 447.
Mirrors
Manual Rearview Mirror
Pull or push the tab under the inside rearview
mirror to adjust it to the night or daytime setting. In
the nighttime setting, the glare from headlamps
behind the vehicle will be less intense.
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 are at the
bottom of the mirror. SeeOnStar®System on
page 182for more information about the services

OnStar®service cannot work unless your vehicle
is in a place where OnStar®has an agreement
with a wireless service provider for service in that
area. OnStar
®service also cannot work unless
you are in a place where the wireless service
provider OnStar
®has hired for that area
has coverage, network capacity and reception
when the service is needed, and technology that
is compatible with the OnStar
®service. 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 your dealer/retailer. 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.

Universal Home Remote System
The Universal Home Remote System provides a
way to replace up to three hand-held
Radio-Frequency (RF) transmitters used to
activate devices such as garage door openers,
security systems, and home lighting.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful
interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following two
conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modi cations to this system by other
than an authorized service facility could void
authorization to use this equipment.
Universal Home Remote System
Operation (With One Triangular LED)
If there is one triangular Light Emitting Diode
(LED) indicator light above the Universal Home
Remote buttons, follow the instructions below.
Do not use the Universal Home Remote 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 Universal Home Remote Transmitter.
187
Page 188 of 684
Read the instructions completely before attempting
to program the Universal Home Remote.
Because of the steps involved, it may be helpful to
have another person available to assist you in
the programming steps
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal Home
Remote programming. It is also recommended that
upon the sale of the vehicle, the programmed
Universal Home Remote buttons should be erased
for security purposes. See “Erasing Universal
Home Remote Buttons” later in section.
When programming a garage door, it is advised to
park outside of the garage. Be sure that people
and objects are clear of the garage door or
gate operator you are programming.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.Programming the Universal Home
Remote System
Follow these steps to program up to three
devices:
1. Press and hold down the two outside
Universal Home Remote buttons, releasing
only when the Universal Home Remote
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 hand-held transmitter to the remaining
two Universal Home Remote buttons.
2. Hold the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from
the Universal Home Remote buttons
while keeping the indicator light in view.
3. At the same time, press and hold both the
desired Universal Home Remote button 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.
