Ignition Positions
Use the key to turn the ignition switch to four
different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition
is turned to LOCK.Notice:If your key seems stuck in LOCK and
you cannot turn it, be sure you are using
the correct key; if so, is it all the way in? Turn
the key only with your hand. Using a tool to
force it could break the key or the ignition
switch. If none of these works, then your
vehicle needs service.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers
when the engine is off.
Lengthy operation of features such as the radio in
the accessory ignition position may drain the
battery and prevent your vehicle from starting.
Do not operate your vehicle in the accessory
ignition position for a long period of time.
C (RUN):This is the position for driving.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.

How OnStar®Service Works
In order to provide you with OnStar®services, your
vehicle’s OnStar®system has the capability of
recording and transmitting vehicle information.
This information is automatically sent to an OnStar
®
Call Center at the time of an OnStar®button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually
includes your GPS location and, in the event of a
crash, additional information regarding the accident
that your vehicle has been involved in (e.g. the
direction from which your vehicle was hit). When
you use the Virtual Advisor feature of OnStar
®
Hands-Free Calling, your vehicle also sends
OnStar®your GPS location so that we can provide
you with location-based 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 theOnStar
®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 conrm 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 modications 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.
150

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.
151

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 Universal Home Remote 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 or garage door
opener by using the “Programming Universal
Home Remote” procedures, regardless of where
you live, replace Step 3 under “Programming
Universal Home Remote” with the following:
Continue to press and hold the Universal Home
Remote button while you press and release every
two seconds (cycle) the hand-held transmitter
button until the frequency signal has been
successfully accepted by the Universal Home
Remote. The Universal Home Remote indicator
light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming
Universal Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home
Remote button for at least half of a second.
The indicator light will come on while the signal
is being transmitted.
Erasing Universal Home Remote
Buttons
To erase programming from the three Universal
Home Remote buttons do the following:
1. Press and hold down the two outside buttons
until the indicator light begins to ash, after
20 seconds. Do not hold the two outside
buttons for longer than 30 seconds.
2. Release both buttons.
The Universal Home Remote is now in the training
(learning) mode and can be programmed at any
time beginning with Step 2 under “Programming
Universal Home Remote” shown earlier in
this section.
Individual buttons cannot be erased, but they can
be reprogrammed. See “Reprogramming a
Single Universal Home Remote Button” following
this section.

Automatic Headlamp System
When it is dark enough outside, the Automatic
Headlamp System turns on the headlamps when
the vehicle is started and after the transaxle
has been shifted out of the PARK (P) position.
The headlamps, taillamps, sidemarker, and parking
lamps will come on. The instrument panel lights
and radio lights will also turn on at normal
brightness. Once on, the system remains on
during these conditions even if the vehicle
is shifted back into PARK (P).
The vehicle has a light sensor on the top of the
instrument panel. Make sure it is not covered or the
system may come on whenever the ignition is on
and the vehicle is shifted out of the PARK (P)
position.
The system could also turn on the lamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the
daytime and nighttime operation of the Daytime
Running Lamps (DRL) and the automatic headlamp
systems, so that driving under bridges or bright
overhead street lights does not affect the system.The DRL and automatic headlamp system are only
affected when the light sensor sees a change in
lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system comes on after the
transmission is shifted out of PARK (P). Once you
leave the garage, it will take about one minute
for the automatic headlamp system to change to
DRL if it is light outside. During that delay, the
instrument panel cluster might not be as bright as
usual. Make sure the instrument panel brightness
control is in the full bright position.
If the vehicle is running and the automatic
headlamp system is already on, it can be turned off
by turning and releasing the headlamp control at
the off position. The automatic headlamp system
stays off until you turn and release the headlamp
control at the off position again. SeeHeadlamps
on page 180.
