2004 CHEVROLET IMPALA alarm

L(Remote Alarm):Press this button to activate an
alarm. The ignition must be in OFF or ACC for the
remote alarm to work. When you press the remote
button, the headlamps will ash, the horn will sound
repeatedly and your interior lamps will turn on attracting
attention if you need it. The alarm will continue until
one of the following occurs:
The remote alarm button is pressed a second time,
the vehicle’s ignition is turned to ON or
an alarm period of 110 seconds has elapsed.
V(Trunk Release):Press the button to release
the trunk.
Operating the remote keyless entry transmitter may
interact with the content theft-deterrent system, if your
vehicle has this option. SeeContent Theft-Deterrent
on page 2-15.
Transmitter Verication
This feature provides feedback that a command has
been received by the vehicle, if your key fob has been
programmed to Mode 3: Full, see Fob Horn (Remote
Audible Verication) underVehicle Personalization
on page 2-44for more information. The headlamps and
back-up lamps will ash on every lock command and
on the rst unlock command. The horn will also
sound once for every lock and twice for the rst unlock
command. Silent operation and other options may
be selected for this feature.
If your vehicle has the optional content theft-deterrent
system, the rst time the remote unlock is received and
the alarm has been previously activated, three ashes
from the headlamps will be seen and three chirps will be
heard to indicate an alarm condition has occurred
since last arming. SeeContent Theft-Deterrent on
page 2-15.

Illumination on Remote Activation
The interior lamps will come on when either the
UNLOCK, the trunk release or the remote alarm button
is pressed. The interior lamps will remain on for
40 seconds or until the ignition is turned to ON or LOCK
is pressed. Locking the doors with the power door
locks will also cause the lamps to turn off. If a door is
opened during the 40 second period, the interior
lamps will remain on while the door is open.
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.
If you prefer, you can complete this procedure yourself.
SeeVehicle Personalization on page 2-44for more
information.

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 an
incorrect 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.
2-15

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.
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 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. SeeSecurity Message on page 3-49.
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
®
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.
SeeFuses and Circuit Breakers on page 5-103. See your
dealer for service.
In an emergency, contact Chevrolet Roadside
Assistance. SeeRoadside Assistance Program on
page 7-6for more information.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to your warning lights and gages could also save
you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briey when you start the engine
just to let you know they’re working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly – and even dangerous. So please get to know
your warning lights and gages. They’re a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 3-52.
