Section 2 Features and Controls
2-1

You can program different feedback modes through the
Driver Information Center (DIC). To program the
modes, press and hold both the unlock and lock buttons
for three approximately three seconds and the DIC
will display the active mode. Then press and hold the
trip odometer reset stem for approximately 2 seconds to
select the modes. For more information seeDIC
Controls and Displays on page 3-30.
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 again, do one of these
three things: wait for 30 seconds; press the panic button
again; or start the vehicle.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking 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. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
2-5

Content Theft-Deterrent
If your vehicle has the
remote keyless entry
system, the vehicle has a
content theft-deterrent
alarm system.
To activate the content theft-deterrent system, do
the following:
1. Close all the doors.
2. Lock the door with the remote keyless entry
transmitter. The security light ashes.
If the vehicle is equipped with OnStar
®, and OnStar®
locks the doors, with all the doors closed, it will activate
the system.
If the lock button on the remote keyless entry transmitter
is pressed, but a door is open, the horn will chirp six
times. Close the open door and the system will
be activated.If a locked door is not opened with the remote keyless
entry transmitter, or OnStar
®, the alarm will go off.
The front turn signal lamps will ash for two minutes,
and the horn will sound for two minutes, then will turn off
to save the battery power.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key, the manual door lock,
or power door lock switch. The system can only
be activated with the remote keyless entry transmitter,
or OnStar
®. You should also remember that you
can start your vehicle with the correct ignition key if the
alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
Always unlock a door with a the remote keyless
entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, you can turn off the
alarm by pressing unlock on the remote keyless
entry transmitter. The alarm won’t stop if you try to
unlock a door any other way.
2-15

Testing the Alarm
The alarm can be tested by following these steps:
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 alarm.
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 5-104.
If the alarm does not sound or the headlamps do not
ash, see your dealer for service.
Passlock®
Your vehicle is equipped with 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 a correct key is not 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 key is turned
to RUN. SeeSecurity Light on page 3-28.
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.

Engine Oil
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.

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.
Don’t let the other end touch anything until the next
step. The other end of the negative (-) cable
doesn’tgo 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.
10. Now start the vehicle with the good battery and run
the engine for awhile.
11. Try to start the vehicle that had the dead battery. If it
won’t start after a few tries, it probably needs service.
