Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are too close to an
airbag when it inates. Avoid wires wrapped
with yellow tape, yellow coverings or yellow
connectors. They are probably part of the
airbag systems. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.
Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)

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 into the
transmitter pocket with the transmitter buttons
facing the front of the vehicle. The transmitter
pocket is inside the console bin located between
the driver and front passenger seats.3. Insert the vehicle key into the key lock cylinder
located on the driver’s door.
4. Turn the key to the unlock position ve times within
ve seconds.
5. The DIC message will display OFF-ACCESSORY
TO LEARN.
6. Press the OFF/ACC button (ignition switch).
7. The DIC will read WAIT 10 MINUTES and will
count down to zero, one minute at a time.
8. The DIC will display OFF-ACCESSORY TO
LEARN again.
9. Press the OFF/ACC button (ignition switch) again.
10. The DIC will again read WAIT 10 MINUTES
and will count down to zero, one minute at a time.
11. The DIC will display OFF-ACCESSORY TO
LEARN again.
12. Press the OFF/ACC button (ignition switch) again.
13. The DIC will again read WAIT 10 MINUTES
and will count down to zero, one minute at a time.
14. A beep will sound and the DIC will read READY
FOR FOB #1. At this time, all previously known
transmitters have been erased.
15. Once the transmitter is recognized and
programmed, a beep will sound and the DIC will
display READY FOR FOB #2.
16. Remove the keyless access transmitter and press
the unlock button twice to initialize it.
2-7

If you have additional transmitters to program, this
process can be repeated until 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 unlock button on each keyless access transmitter
twice. After performing this process, transmitters
previously programmed will no longer work with your
vehicle and must be reprogrammed.
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. The DIC
may display KEY FOB BATTERY LOW.
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 console
bin transmitter pocket with the buttons facing to the
front of the vehicle. Then, with the vehicle in PARK (P)
or NEUTRAL (N), press the brake pedal and the
start button. SeeStarting the Engine on page 2-24,
for additional information about your vehicle’s
electronic keyless ignition with push button start.Although this will start the vehicle, it is recommended
that you replace the transmitter battery as soon as
possible.
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.
To replace the battery, do the following:
1. Insert a coin or similar object into the slot on the
back of the transmitter and carefully pry apart the
front and back.
2. Carefully pull the battery out of the transmitter.
2-8

3. Put the new battery in the transmitter, positive (+)
side down. Use a battery type CR2032 or
equivalent.
4. Reassemble the transmitter. Make sure to put it
together so water will not get inside the transmitter.
5. Test the transmitter.
Remote Vehicle Start
This feature allows you to start the engine from outside
the vehicle.
/(Remote Start):To start the vehicle using the
remote start feature, do the following:
1. Aim the remote keyless access transmitter at the
vehicle.
2. Press the transmitter’s lock button, release it, and
then immediately press and hold the transmitter’s
remote start button for at least three seconds or until
the vehicle’s turn signal lamps ash. The vehicle’s
doors will be locked.
3. When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.
4. Repeat Steps 1 and 2 while the engine is still
running to add 10 minutes of engine running.If the vehicle is left running it will automatically shut off
after 10 minutes unless a time extension has been
done. To manually shut off a remote start, do any of the
following:
Aim the keyless access transmitter at the vehicle
and press the remote start button until the parking
lamps turn off.
Turn on the hazard warning ashers.
Press the OFF/ACC button (ignition switch). See
Ignition Positions on page 2-22.
Turn on the valet lockout switch. SeeValet Lockout
Switch on page 2-21.
When you enter the vehicle during a remote start, press
the brake pedal and press the start button on the
keyless ignition switch to transition from remote start
operation to normal vehicle operation.
Before the remote vehicle start system can be operated
with the keyless access transmitter it must be activated.
The remote start system is turned on through the vehicle
personalization system.
2-9

You can also program the remote vehicle start system
to start up the vehicle’s automatic climate control
system. If this feature is turned on, the system monitors
the outside temperature and turns on the rear window
defogger, front window defogger, and heated or
ventilated seats, if equipped. See “Personal Settings
Menu” underVehicle Personalization on page 2-47.
Laws in some local communities may restrict the use of
remote starters, for example, requiring a person
using remote start to have the vehicle in view when
doing so. Check local regulations for any requirements
on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate starts,
each with 10 minutes of engine running. If you press the
remote start button on the keyless access transmitter
again before the rst 10 minutes of engine running time
has expired, 10 minutes is added to the remaining
minutes. For example, if the remote start button
is pressed again after ve minutes of the engine run
time, 10 minutes is added and you now have 15 minutes
with the engine running. Once two remote starts or
20 minutes of the engine running have been provided,
the vehicle must be started using the keyless access
with pushbutton start feature, if the engine needs to be
restarted. SeeStarting the Engine on page 2-24for
more information regarding the keyless ignition.The remote start feature will not operate if any of the
following occur:
The check engine light is displayed.
The valet lockout switch is on.
The keyless access transmitter is in the vehicle.
The vehicle’s hood is open.
The vehicle personalization feature is not enabled.
An unauthorized vehicle entry or a vehicle theft
was attempted.
Your keyless access transmitter, with the remote start
button, provides an increased range of operation.
However, the range may be less while the vehicle is
running. As a result, you may need to be closer to your
vehicle to turn it off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeKeyless Access
System on page 2-3.
