Matching Transmitter(s) to
Your Vehicle
Each keyless access transmitter is coded to prevent
another transmitter from working with your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. Once your dealer has coded the new transmitter,
the lost transmitter will not work with your vehicle.
Each vehicle can have a maximum of four transmitters
matched to it.
To match a new transmitter to your vehicle when you
have a recognized transmitter, do the following:
1. The vehicle must be off.
2. Have the recognized and new, unrecognized
transmitters on your person.3. Go to the rear of the vehicle and insert the vehicle
key into the key cylinder located on the lower
rear fascia on the driver’s side of the vehicle.
SeeTrunk on page 2-12for more information on
the key cylinder.
4. Open the trunk.
5. Turn the key ve times within ve seconds.
6. The Driver Information Center (DIC) will display
READY FOR FOB #X. X can be 2, 3 or 4.
7. Place the new, unrecognized transmitter in the
glove box transmitter pocket with the buttons
facing to the right.
8. Once the transmitter is programmed, a beep will
sound. The DIC will display READY FOR #X,
where X can be 3 or 4, or MAX # FOBS LEARNED.
9. Press the ACC button.

The Canadian immobilizer standard requires Canadian
owners to see their GM dealer for matching new
transmitters when a recognized transmitter is not
available. United States owners are permitted to match
a new transmitter to their vehicle when a recognized
transmitter is not available. The procedure will require
three ten minute cycles to complete the matching
process. Do the following:
1. The vehicle must be off.
2. Place the new, unrecognized transmitter in the
glove box transmitter pocket with the buttons
facing to the right.
3. Go to the rear of the vehicle and insert the vehicle
key into the key cylinder located on the lower rear
fascia on the driver’s side of the vehicle. SeeTrunk
on page 2-12for more information on the key
cylinder.
4. Open the trunk.
5. Turn the key ve times within ve seconds.
6. The DIC message will display OFF-ACC TO LEARN.
7. Press the ACC button.
8. The DIC will read WAIT 10 MINUTES and will
count down to zero, one minute at a time.9. The DIC will display OFF-ACC TO LEARN again.
10. Press the ACC button.
11. The DIC will read WAIT 10 MINUTES and will
count down to zero, one minute at a time.
12. The DIC will display OFF-ACC TO LEARN again.
13. Press the ACC button.
14. The DIC will read WAIT 10 MINUTES and will
count down to zero, one minute at a time.
15. A beep will sound and the DIC will read READY
FOR FOB #1. At this time, all previously known
transmitters have been erased.
16. Once the transmitter is recognized and
programmed, a beep will sound and the DIC will
display READY FOR FOB #2.
If you have additional transmitters to program, take
transmitter 1 out of the transmitter pocket and place
transmitter 2 in the pocket. This can be done repeatedly
until up to four transmitters have been programmed.
The DIC will then display MAX # FOBS LEARNED and
will exit the programming mode.
When you are done programming transmitters, press
the ACC button.

Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery.
A weak battery may also cause the DIC to display
NO FOBS DETECTED when you try to start the vehicle.
If this happens, place the transmitter in the glove box
transmitter pocket with the buttons facing to the right.
Then, with the vehicle in PARK (P) or NEUTRAL (N),
press the brake pedal and the START button. Although
this will start the vehicle, it is recommended that you
replace the transmitter battery as soon as possible.
The DIC may display FOB BATTERY LOW.
Notice:When replacing the battery, use care not
to touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.1. Insert a coin or similar object into the slot on the
back of the transmitter and gently pry apart the
front and back.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter, positive (+)
side up. Use a battery, type CR2032, or equivalent.
4. Reassemble the transmitter. Make sure to put
it together so water will not get in.
5. Test the transmitter.

Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the engine is turned off:
Radio
Power Windows
Audio Steering Wheel Controls
Power to these accessories stops after 10 minutes
or if a door is opened. If you want power for
another 10 minutes, close all the doors and press
the ACC button to place the vehicle in accessory
mode. Press the button again and the vehicle will
return to RAP.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
The keyless access transmitter must be in the vehicle
for the ignition to work.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot on the brake pedal, press the
START button located on the instrument panel.
If there is not a keyless access transmitter present
or if there is something causing interference
with it, the DIC will display NO FOB DETECTED.
SeeDIC Warnings and Messages on page 3-67
for more information. When the engine begins
cranking, let go of the button. The idle speed will go
down as your engine gets warm.
If the battery in the keyless access transmitter is
weak, the DIC will display FOB BATTERY
LOW. You can still drive the vehicle. See “Battery
Replacement” underKeyless Access System
Operation on page 2-5for more information.
2-22
Notice:Holding the button in for longer than
15 seconds at a time will cause the vehicle’s battery
to be drained much sooner. This can also cause
damage to the starter motor. Wait 15 seconds
between each try to avoid draining your vehicle’s
battery or damaging the starter.
2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.Stopping Your Engine
Move the shift lever to PARK (P) and press the ACC
button located on the instrument panel. If the shifter is
not in PARK (P), the vehicle will go into the accessory
mode, the engine will turn off and the DIC will display
SHIFT TO PARK. When the shifter is moved to
PARK (P), the vehicle will go into the RAP mode, if all
doors are closed. The ignition mode will change to OFF,
if a front door is opened. SeeRetained Accessory
Power (RAP) on page 2-22for more information.
If the keyless access transmitter is not detected
while going to off, the DIC will display
NO FOB – OFF OR RUN?
SeeDIC Warnings and Messages on page 3-67for
more information.

Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
Check Engine light is on or not working properly.
To perform a Check Engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 2-21. Press the bottom of the ACC button
on the instrument panel and hold the button down
for ve seconds. The instrument panel, including
the Check Engine light, will light up and the ignitionwill be on, but the engine will not start — if you press
the bottom of the ACC button only brie y, less than
ve seconds, the accessory power mode will be turned
on, but not the ignition. After the bulb check, be sure
to press and release the ACC button again to turn
the ignition off and avoid draining the vehicle’s battery.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection. This can
happen if you have recently replaced your battery or
if your battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.

NO FOB DETECTED:This message is displayed if
the vehicle does not detect the presence of a keyless
access transmitter when you have attempted to start the
vehicle or a vehicle door has just closed. The following
conditions may cause this message to appear:
Driver-added equipment plugged into the accessory
power outlet on the center console is causing
interference. Examples of these devices are cell
phones and cell phone chargers, two-way radios,
power inverters, or similar items. Try moving
the keyless access transmitter away from these
devices when starting the vehicle. In addition,
PDA devices and remote garage and gate openers
may also generate Electromagnetic Interference
(EMI) that may interfere with the keyless access
transmitter. Do not carry the keyless access
transmitter in the same pocket or bag as these
devices.
The vehicle is experiencing Electromagnetic
Interference (EMI). Some locations, such as
airports, automatic toll booths, and some gas
stations, have EMI elds which may interfere with
your keyless access transmitter.
If moving the transmitter to different locations within
the vehicle does not help, place the transmitter in the
glove box transmitter pocket with the buttons facing
to the right and then press the START button.

NO FOB, OFF OR RUN?:When this message displays,
it means that the keyless access transmitter is not
detected inside the vehicle while you are trying to turn
the ignition off. Your vehicle may be near a strong
radio antenna signal causing the keyless access system
to be jammed. The vehicle will remain in ACC until off
or START has been pressed or ve minutes has
expired. If you turn the ignition off and you cannot nd
the keyless access transmitter, you will not be able
to restart the vehicle. The keyless access transmitter
needs to be inside of the vehicle in order for the vehicle
to start. SeeStarting the Engine on page 2-22for
more information.
OVER SPEED WARNING:This message is displayed
