Remote Keyless Entry (RKE)
System Operation
You can lock and unlock the vehicle’s doors and disarm
or arm the theft-deterrent system from about 3 feet (1 m)
up to 30 feet (9 m) away using the Remote Keyless
Entry (RKE) transmitter. SeeContent Theft-Deterrent
on page 2-14for additional information.
UNLOCK:Press this
button to unlock the driver’s
door and turn on the
interior lamps. The parking
lamps may also ash,
and the horn may chirp,
when this button is pressed.
Press the unlock button again within three seconds and
all of the doors will unlock.LOCK:Press this button to lock all the doors. The
parking lamps may also ash and the horn may chirp
when this button is pressed.
If a door is open or ajar when the lock button is pressed,
the doors will lock, but the theft-deterrent system will
not arm until the open door is closed.
Different feedback modes can be programmed through
the Driver Information Center (DIC). See “Remote
Keyless Entry Feedback” underDIC Operation and
Displays on page 3-40.
L(Panic):Press this button to make the horn sound
and the headlamps and taillamps ash for up to
30 seconds. To turn them off, do one of these three
things: wait for 30 seconds; press the panic button
again; or start the vehicle.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle has a
content theft-deterrent
alarm system.
To activate the content theft-deterrent system:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.
If the lock button on the remote keyless entry transmitter
is pressed, but a door is open, the doors will lock,
the lights may ash and the horn may sound. Close
the open door and the alarm system will arm.If a locked door is not opened using the remote keyless
entry transmitter, or by OnStar
®, the alarm will go off.
First, a pre-alarm will sound the horn at reduced
intensity for 10 seconds. Then, the front turn signal
lamps will ash for two minutes, and the horn will sound
for two minutes. The alarm will then turn off to save
battery power.
Starting the engine with the correct key will shut off the
pre-alarm or alarm at any time.
Remember, the theft-deterrent system will not activate
if you lock the doors with the key, the manual door lock,
or power door lock switch. The system can only be
activated using the remote keyless entry transmitter, or
by OnStar
®. SeeOnStar®System on page 2-48for
additional information. You should also remember that
you can start your vehicle with the correct 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 arm the theft-deterrent
system, the vehicle should be locked with the
manual door lock lever, the power door lock switch,
or the key, after the doors are closed.
If the content theft-deterrent system is armed,
unlock the doors by pressing the unlock button
on the remote keyless entry transmitter or by
OnStar
®. Unlocking a door any other way will
activate the alarm.
2-14

If you set off the alarm by accident, you can turn it off
by pressing unlock on the remote keyless entry
transmitter, starting the vehicle with the correct key, or
by having OnStar
®unlock the doors. The alarm will
not stop if you try to unlock a door any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Unlock the door with the manual door lock and
open the door. This should set off the pre-alarm.
Wait 10 seconds for the full alarm to activate.
3. To turn the alarm off, press the unlock button
on the remote keyless entry transmitter or start
the engine.
If the alarm does not sound when it should but the
lights ash, check to see if the horn works. The horn
fuse may be blown. To replace the fuse, seeFuses
and Circuit Breakers on page 5-102.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer/retailer for service.
Passlock®(U. S. Only)
Your vehicle has the Passlock®theft-deterrent system.
Passlock®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If an incorrect key is used or the
ignition lock cylinder is tampered with, the fuel system
is disabled and the vehicle will not start.
During normal operation, the security light will turn off
approximately ve seconds after the engine is started.
SeeSecurity Light on page 3-39.
If the engine stalls and the security light ashes, wait
about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release
the key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the engine
off. However, your Passlock
®system is not working
properly and must be serviced by your dealer/retailer.
Your vehicle is not protected by Passlock
®at this time.
See your dealer/retailer for service.
In an emergency, call the Roadside Assistance Center.
SeeRoadside Assistance Program on page 7-6.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

4. Open the hoods and locate the batteries on both
vehicles. You will use the positive (+) battery terminal
and the remote negative (−) jump starting terminal to
jump start your vehicle. To access the positive (+)
battery terminal, open the terminal cover. See
Engine Compartment Overview on page 5-12for
more information on the terminal locations.
{CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
ashlight if you need more light.
Be sure the batteries have enough water. You
do not need to add water to the ACDelco
®
battery (or batteries) installed in your new
vehicle. But if a battery has ller caps, be sure
the right amount of uid is there. If it is low,
add water to take care of that rst. If you do
not, explosive gas could be present.
Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ush the place
with water and get medical help immediately.
{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.
5. Check that the jumper cables do not have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (−) will go to a heavy,
unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative (−)oryou
will get a short that would damage the battery
and maybe other parts too. And do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.
5-43

6. Connect the red positive (+) cable to the positive (+)
terminal of the dead battery. Use a remote
positive (+) terminal if the vehicle has one.
7. Do not let the other end touch metal. Connect it to
the positive (+) terminal of the good battery. Use a
remote positive (+) terminal if the vehicle has one.
8. Now connect the black negative (−) cable to the
negative (−) terminal of the good battery. Use a
remote negative (−) terminal if the vehicle has one.
Do not let the other end touch anything until the
next step. The other end of the negative (−) cable
does not go to the dead battery. It goes to a
heavy, unpainted metal engine part, or to a remote
negative (−) terminal on the vehicle with the
dead battery.
9. Connect the other end of the negative (−) cable at
least 18 inches (45 cm) away from the dead battery,
but not near engine parts that move. The electrical
connection is just as good there, and the chance
of sparks getting back to the battery is much less.
Your vehicle has a remote negative (−) terminal,
marked GND (Ground), for this purpose.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that had the dead battery. If
it will not start after a few tries, it probably needs
service.Notice:If the jumper cables are connected or
removed in the wrong order, electrical shorting may
occur and damage the vehicle. The repairs would
not be covered by your warranty. Always connect
and remove the jumper cables in the correct
order, making sure that the cables do not touch
each other or other metal.
