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/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 7-16.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, or airbag wiring
can affect the operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position,
which includes sensors that are part of the
passenger’s seat. The passenger sensing system
may not operate properly if the original seat
trim is replaced with non-GM covers, upholstery

be re-coded to match the new transmitter. The
lost transmitter will no longer work after the new
transmitters are re-coded. Each vehicle can have
up to four transmitters matched to it.
Battery Replacement
Replace the battery if the KEY FOB BATT LOW
message displays in the DIC. See “KEY FOB BATT
LOW” underDIC Warnings and Messages on page 3-43
Notice:When replacing the battery, use care not

transferred to these surfaces may damage the
transmitter.
2-6

To replace the battery in the RKE transmitter:
1. Separate the halves of the transmitter with a at,
thin object inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing up.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly.
Remote Vehicle Start
Your vehicle may have a remote start feature. This
feature allows you to start the engine from outside the
vehicle. It may also start the vehicle’s heating or air
conditioning systems. When you start your vehicle using
the remote start feature, the climate control system
will come on and adjust the interior to the temperature
settings that you left it set to when you turned the
vehicle off.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require
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
per ignition cycle, each with 10 minutes of engine
running time.

{CAUTION:
If you have a manual transmission removing
the key from the ignition switch will lock the
steering column and result in a loss of ability
to steer the vehicle. This could cause a
collision. If you need to turn the engine off
while the vehicle is moving, turn the key to
ACC/ACCESSORY.
ACC (ACC/ACCESSORY):This position operates
some of your electrical accessories. It unlocks the
steering wheel and ignition.
R(ON/RUN):This is the position the switch returns
to after you start your engine and release the switch.
The switch stays in the ON/RUN position when the
engine is running. But even when the ignition is
not running, you can use ON/RUN to operate your
electrical accessories and to display some warning
and indicator lights.The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/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.
/(START):This position starts the engine. When
the engine starts, release the key. The ignition switch
will return to ON/RUN for normal driving.
A warning tone will sound if you open the driver’s door
while in LOCK/OFF or ACC/ACCESSORY, when
the key has not been removed from the ignition.
Key In the Ignition
Never leave your vehicle with the keys inside, as it is
an easy target for joy riders or thieves. If you leave the
key in the ignition and park your vehicle, a chime will
sound, when you open the driver’s door. Always
remember to remove your key from the ignition and take
it with you. This will lock your ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if you leave the key in the
ignition while your vehicle is parked. You may not be
able to start your vehicle after it has been parked for
an extended period of time.

Column Lock Release
For vehicles with an automatic transmission, the
following procedure allows the ignition to be turned
to LOCK/OFF and ignition key removal in case of a
dead battery or low voltage battery.
1. Make sure the shift lever is in PARK (P).
2. Remove the cover from the bottom of the
steering column.3. Locate the plunger.
4. Press and hold the plunger while turning the
ignition key to LOCK/OFF. Remove the key.
Have your vehicle serviced at your dealer/retailer as
soon as possible.
2-24

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently to allow the oil to warm up
and lubricate all moving parts.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects components. If the ignition
key is turned to the START position, and then
released when the engine begins cranking, the
engine will continue cranking for a few seconds
or until the vehicle starts. If the engine does not start
and the key is held in START for many seconds,
cranking will be stopped after 15 seconds to prevent
cranking motor damage. To prevent gear damage,
this system also prevents cranking if the engine
is already running. Engine cranking can be stopped
by turning the ignition switch to ACC/ACCESSORY
or LOCK/OFF.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor and holding it there as you
hold the key in START for up to a maximum
of 15 seconds. Wait at least 15 seconds between
each try, to allow the cranking motor to cool
down. When the engine starts, let go of the key
and accelerator. If the vehicle starts briey but
then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race
the engine immediately after starting it. Operate
the engine and transmission gently until the
oil warms up and lubricates all moving parts.
Notice:The 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/retailer. If you do not, your
engine might not perform properly. Any resulting
damage would not be covered by your vehicle’s
warranty.
