LOCK: Pressing this button once will lock all of the
doors. Press LOCK again within three seconds and the
horn will chirp.
Operating the keyless entry transmitter may interact
with the theft
-deterrent system. See ªContent-Theft
Deterrentº in the Index.
Remote Panic Alarm
When the button with the horn symbol on the keyless
entry transmitter is pressed, the horn will sound and the
headlamps and taillamps will flash for up to 30 seconds.
This can be turned off by pressing the horn button again,
waiting for 30 seconds, or starting 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 only four transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
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.

Content Theft-Deterrent
(If Equipped)
Your vehicle may be equipped with a Content
Theft
-Deterrent alarm system.
With this system, the
SECURITY message will
flash as you open the door
(if your ignition is off).
This message reminds you to activate the theft
-deterrent
system. Here's how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The SECURITY
message should come on and stay on. If using the
remote keyless entry transmitter, the door does not
need to be open.
3. Close all doors. The SECURITY message should go
off after approximately 15 seconds. The alarm is not
armed until the SECURITY message goes off.If a door is opened without the key or the remote keyless
entry transmitter, the alarm will go off. Your vehicle's
headlamps will flash and the horn will sound for about
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 or use the manual door
lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. 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 key, or use the remote
keyless entry transmitter. Unlocking a door any other
way will set off the alarm if the system has been armed.
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 remote keyless entry transmitter or by
placing the key in the ignition and turning it to START.

2-17
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for the
SECURITY message to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door.
This should set off the alarm.
If the alarm does not sound when it should but the
vehicle's headlamps flash, check to see if the horn
works. The horn fuse may be blown. To replace the fuse,
see ªFuses and Circuit Breakersº in the Index.
If the alarm does not sound or the vehicle's headlamps
do not flash, the vehicle should be serviced by an
authorized service center.
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, fuel is disabled.
If the engine stalls and the SECURITY message flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the SECURITY message
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.
Your vehicle is not protected by Passlock at this time.
You may also want to check the fuse (see ªFuses and
Circuit Breakersº in the Index). See your dealer
for service.
In an emergency, call the GM Roadside Assistance
Center. See ªRoadside Assistanceº in the Index.

The lever on the left side of the steering column
includes your:

Turn Signal and Lane Change Indicator

Headlamp High/Low Beam Changer

Flash
-to-Pass

Windshield Wipers

Windshield Washer

Turn Signal and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever will return automatically.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.
If you move the lever all the way up or down, and the arrow
flashes at twice the normal rate, a signal bulb may be burned
out and other drivers may not see your turn signal.
If a bulb is burned out, replace it to help avoid an accident.
If the arrows don't go on at all when you signal a turn,
check for burned
-out bulbs or a blown fuse (see ªFuses
and Circuit Breakersº in the Index).

2-53
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each flash of the
turn signal. To turn off the chime, move the turn signal
lever to the off position.
Headlamp High/Low Beam Changer
To change the headlamps from low to high beam or high
to low beam, pull the multifunction lever all the way
toward you. Then release it.
When the high beams are
on, this light on the
instrument panel also
will be on.
Flash-To-Pass Feature
This feature allows you to use your high-beam
headlamps to signal a driver in front of you that you
want to pass. It works even if your headlamps are off.
To use it, pull the turn signal lever toward you, but not
so far that you hear it click.If your headlamps are off or on low
-beam, your
high
-beam headlamps will turn on. They'll stay on as long
as you hold the lever toward you and the high
-beam
indicator on the instrument panel will come on. Release
the lever to turn the high
-beam headlamps off.

Exterior Lamps
Your parking lamp and headlamp switch is on the
driver's side of your instrument panel.
Turn the knob clockwise to the parking lamps symbol to
manually turn on the following:

Parking Lamps

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel LightsTurn the knob clockwise to the master lamps symbol to

Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor located on
the top of the instrument panel in the defroster grille.
Be sure it is not covered, or the system will be on
whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting longer
than the delay.

2-59
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
You may be able to turn off your automatic headlamp
system. See ªDaytime Running Lamps (DRL)º later in
this section for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in OFF, LOCK or ACCESSORY. To disable the
chime, turn the thumbwheel all the way down. In the
automatic mode, the headlamps turn off once the
ignition key is in OFF.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
Fully functional daytime running lights are required
on all vehicles first sold in Canada.The DRL system will come on when the following
conditions are met:

the ignition is on,

the headlamp switch is in automatic headlamp mode,

the automatic transmission is not in PARK (P),

the light sensor determines it is daytime and

the parking brake is released.
When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps or the
last chosen headlamp setting that was used.
When you turn the headlamp switch off, the headlamps
will go off, and your DRL lamps will illuminate,
provided it is not dark outside.
To idle an automatic transmission equipped vehicle with
the DRL off, set the parking brake. Shifting the
transmission into PARK (P) will also allow you to idle
the vehicle with the DRL off. The DRL will stay off
until you release the parking brake or shift the
transmission out of PARK (P).

2-60
To idle a manual transmission equipped vehicle with the
DRL off, set the parking brake. The DRL will stay off
until you release the parking brake.
The following procedure applies only to vehicles first
sold in the United States.
When necessary, you may turn off the Automatic
Headlamp System and the Daytime Running
Lamps (DRL) feature by following these steps:
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you the system
is off. The system will revert back to the automatic
mode when the ignition is turned off and on again.
3. To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(the chime will sound), or turn the ignition off
and on again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Fog Lamps (If Equipped)
If your vehicle has fog lamps, use them for better vision in
foggy or misty conditions. Your parking lamps and/or
low
-beam headlamps must be on for your fog lamps to work.
The fog lamp switch is
located on the left side of
your instrument panel.
Press the switch to turn the fog lamps on. Press the
switch again to turn them off. An indicator light will
glow in the switch when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use the fog lamps in the
dark without turning on the headlamps.
The fog lamps will go off whenever the high
-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
