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 may have the optional content
theft-deterrent alarm system.
With this system, a light on the radio will ¯ash.
This light 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 light on
the radio should come on and stay on. If you
are using the remote keyless entry transmitter, the
door does not need to be open.
3. Close all doors. The light on the radio will slowly
¯ash once the system is armed.
Once armed, the alarm will go off if someone tries to
enter the vehicle (without using the remote keyless entry
transmitter or a key) or turns the ignition on with anincorrect key. The horn will sound and the headlamps
and back-up lamps will ¯ash for approximately
two minutes.
When the alarm is armed, the trunk may be opened
with the remote keyless entry transmitter. If you use the
key to open the trunk, the alarm will sound. The
power door lock switches are also disabled. You must
use your remote keyless entry transmitter or your key to
unlock the doors when the system is armed.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
lock switch to lock the doors while any door or the
trunk is open and the key is removed from the ignition.
The light on the radio ¯ashes quickly to let you know
when the system is ready to arm with the power
door lock switches. The light on the radio will stop
¯ashing and stay on when you press the bottom of the
power lock switch, to let you know the system is
arming. After all doors and the trunk are closed and
locked, the light on the radio will ¯ash slowly to let you
know the system is armed.

Arming with the Remote Keyless Entry
Transmitter
Your alarm system will arm when you use your remote
keyless entry transmitter to lock the doors, if the key
is not in the ignition. The light on the radio will turn on to
let you know the system is arming. After all doors and
the trunk are closed and locked, the light on the
radio will begin ¯ashing at a very slow rate to let you
know the system is armed.
Disarming with the Remote Keyless
Entry Transmitter
Your alarm system will disarm when you use your
remote keyless entry transmitter to unlock the doors.
The light on the radio will go off to let you know
the system is no longer armed.
The ®rst time a remote UNLOCK command is received,
three ¯ashes will be seen and three horn chirps
heard to indicate an alarm condition has occurred since
last arming.
Disarming with Your Key
Your alarm system will disarm when you use your key
to unlock the doors. The light on the radio will go
off to let you know the system is no longer armed.
Passlockž
Your vehicle is equipped with the Passlockž
theft-deterrent system.
Passlock
žis a passive theft-deterrent system. Passlockž
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 and
the engine will not start.
During normal operation, the SECURITY message will
be displayed after the key is turned to the ON ignition
position. See
Security Message on page 3-46.
If the engine stalls and the SECURITY message
¯ashes, wait until the light stops ¯ashing before trying to
restart the engine.
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
ž
system is not working properly and must be serviced by
your dealer. Your vehicle is not protected by Passlockž
at this time. You may also want to check the fuse.
SeeFuses and Circuit Breakers on page 5-95. See your
dealer for service.
In an emergency, contact Chevrolet Roadside
Assistance. See
Roadside Assistance Program on
page 7-5for more information.

Storage Areas
Glove Box
Use the key to lock and unlock the glove box. To open,
lift the latch.
Front Storage Area
If your vehicle has the split bench front seat, there is an
armrest located in the center of the seat. Dual
cupholders are located in front of the armrest.
Center Console Storage Area
Your vehicle may be equipped with a center console. It
has cupholders, a cassette tape and CD storage
area. To open the console's storage area, pull up on the
latch located in the front of the console lid.
Rear Storage Area
If your vehicle has the split folding rear seat, there will
be two cupholders in the rear seat armrest. To
access them, pull down on the cloth strap located
toward the top of your center back seat cushion.
Convenience Net
Your vehicle may have a convenience net. You'll see it
on the back wall of the trunk.
Put small loads, like grocery bags, behind or inside the
net. It can help keep them from falling over during
sharp turns or quick starts and stops.
The net isn't for larger, heavier loads. Store those in the
trunk as far forward as you can.
You can unhook the net so that it will lie ¯at when
you're not using it.

Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to work.
When the key is removed, interior illumination will
activate and remain on until one of the following occurs:
·The ignition is moved to ON,
·the power door locks are activated, or
·an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. This feature prohibits the dimming of your
instrument panel displays during the daylight while
the headlamps are on so that you'll still be able to see
the displays.
Reading Lamps
Your vehicle may be equipped with reading lamps that
are located on the assist handles in the headliner.
These lamps and the interior courtesy lamps come on
when any door is opened. Press the lens to turn
them on. Press it again to turn them off.
Dome Lamp
If your vehicle has this feature, the dome lamp will
come on when you open a door. You can also turn this
lamp on by turning the exterior lamps control clockwise
as far as it will go. Vehicles that have the optional
sunroof do not have a dome lamp.
Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave on the
interior courtesy lamps, reading/map lamps, visor
vanity lamps, trunk lamp or glove box lamps. If you leave
any of these lamps on, they will automatically turn off
after 10 minutes, if the ignition is moved to OFF.
The lamps won't come back on again until you do
the following:
·Turn the ignition on, or
·turn the exterior lamps control off, then on again.
If your vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn off the lamps
after only three minutes.
Battery rundown protection will also work if the
headlamps are left on. After having been left on for
10 minutes, the headlamps and the parking lamps will
¯ash three times. They will remain on for one more
minute before being turned off automatically.
