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. You do
not want the system to inate while someone is
working on your vehicle. Your dealer 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 600.
{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.
The airbag system does not need regular
maintenance.

At times you may notice a decrease in operating
range. This is normal for any RKE system. If
the transmitter does not work or if you have to
stand closer to your vehicle for the transmitter to
work, try this:
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement
is necessary. See “Battery Replacement”
underRemote Keyless Entry (RKE) System
Operation on page 95.
If you are still having trouble, see your dealer
or a qualied technician for service.
Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked
from about 3 feet (1 m) up to 65 feet (20 m)
away with the Remote Keyless Entry (RKE)
transmitter.
If your vehicle has the remote start feature
you can also start your vehicle with the RKE
transmitter. The RKE transmitter, with the remote
start button, provides an increased operating
range of 195 feet (60 m) away. However,
the operating 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 start it.
There are other conditions which can affect the
performance of the transmitter. SeeRemote
Keyless Entry (RKE) System on page 94.

Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about four years.
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 REPLACE BATTERY IN REMOTE KEY
message in the vehicle’s DIC will display if the
RKE transmitter battery is low. See “REPLACE
BATTERY IN REMOTE KEY” underDIC Warnings
and Messages on page 267for additional
information.
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 in the RKE transmitter do
the following:
1. Use a at object with a thin edge into the
notch, located below the vehicle locator/panic
alarm button, and separate the bottom half
from the top half of the transmitter.
2. Remove the old battery, but do not use a
metal object to do this.

3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
4. Snap the front and the back of the
transmitter together.
5. Test the operation of the transmitter with
the vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle. It may also start up
the vehicle’s heating or air conditioning systems
and rear window defogger. Normal operation of the
system will return after the key is turned to the
RUN position.
If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate controlsystem, during remote start the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.
If your vehicle has heated seats, they will turn
on during colder outside temperatures and will shut
off when the key is turned to RUN.
Laws in some communities may restrict the use
of remote starters. For example, some laws
may require a person using the 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 RKE 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, seeRemote
Keyless Entry (RKE) System on page 94for
additional information.

3. Close all doors. The security light should go
off after about 30 seconds. The alarm is not
armed until the security light goes off.
If the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the
delay timer has expired. SeeDelayed Locking
on page 103.
The content theft deterrent system does not
sense if the midgate is open or ajar, therefore,
vehicle contents may not be protected if the
midgate is left open or ajar.
If a locked door is opened without the key or the
RKE transmitter, a ten second pre-alarm will occur.
The horn will chirp and the lights will ash. If the
door is not unlocked using the key or by pressing
the unlock button on the RKE transmitter during
the ten second pre-alarm, the alarm will go off.
The headlamps and parking lamps will ash
for two minutes, and the horn will sound for
30 seconds, then will turn off to save the battery
power. You can choose different feedback options
for the alarm. SeeDIC Vehicle Customization
(With DIC Buttons) on page 278.Remember, the theft-deterrent system will not
activate if you lock the doors with the vehicle’s key
or use the manual door lock. It activates only if
you use a power door lock switch while the door is
open, or when you use the RKE transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm
has been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the
theft-deterrent system, the vehicle should
be locked with the door keyafterthe doors
are closed.
Always unlock a door with a key, or use the
RKE transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any
door with the key. You can also turn off the alarm
by pressing unlock on the RKE transmitter.
The alarm will not stop if you try to unlock a
door any other way.

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:Using a tool to force the key from
the ignition switch could cause damage
or break the key. Use the correct key
and turn the key only with your hand.Make sure the key is all the way in. If it is,
turn the steering wheel left and right while
you turn the key hard. If none of this 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 and the
RUN 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. It is
the position the switch returns to after the engine
starts, and you release the key.
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.
123

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.
Retained Accessory Power (RAP)
Your vehicle has a Retained Accessory
Power (RAP) feature which will allow certain
features on your vehicle to continue to work
up to 10 minutes after the ignition key is
turned to LOCK.The radio, power windows, if the vehicle has a
sunroof and the OnStar
®System, will work when
the ignition key is in RUN or ACCESSORY.
Once the key is turned from RUN to LOCK, these
features will continue to work for up to 10 minutes
or until a door is opened.
Starting the Engine
To place the transmission in the proper gear:
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position -- this is a safety feature.
To restart when you are already moving,
use NEUTRAL (N) only.
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.
124

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 the
ACCESSORY or LOCK position.
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 allow
the cranking motor to 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: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.
