2001 CHEVROLET IMPALA alarm

2-10 Operation
Press UNLOCK once
to unlock the driver's
door and to turn on
the interior lamps.
(See ªIllumination on
Remote Activationº
in the Index for
more details).
Pause for about one second, then press UNLOCK again
within five seconds to unlock the passengers' doors.
To lock all doors, press LOCK. To release the trunk,
press the trunk symbol on the remote keyless entry
transmitter. The shift lever must be in PARK (P) for
this to work.
Operating the remote keyless entry transmitter may
interact with the content theft
-deterrent system (if the
vehicle has this option). See ªContent Theft
-Deterrent
Systemº in the Index.Panic Alarm Button
This feature allows you to activate an alarm by pressing
a button on the remote keyless entry transmitter. The
ignition must be in OFF or ACC for the instant alarm to
work. When you press the horn button on the remote
keyless entry transmitter, the headlamps will flash, the
horn will sound repeatedly and your interior lamps will
illuminate attracting attention if you need it. The alarm
will continue until one of the following occurs:

You press the alarm button on the remote keyless
entry transmitter a second time,

the ignition is in ON or

an alarm period of 110 seconds has elapsed.
Transmitter Verification (If Equipped)
This feature provides feedback to the holder of the
remote keyless entry transmitter that a command
has been received by the keyless entry receiver. The
headlamps and back
-up lamps will flash on every lock
and the first unlock command, and the horn will sound
once for every lock and twice for the first unlock
command. Silent operation and other options may be
selected for this feature (see ªVehicle Customization
Settingsº in the Index).

2-11
If your vehicle has the optional content theft-deterrent
system, the first time the remote unlock is received,
three flashes and chirps will be seen to indicate an alarm
condition has occurred since last arming. See ªContent
Theft
-Deterrent Systemº in the Index.
Illumination on Remote Activation
This feature provides interior illumination when a
remote keyless entry unlock command is received and
executed, the trunk release button is pressed or when
the panic alarm is activated. The interior lamps will
illuminate until the ignition is turned to ON or until an
illumination period of 40 seconds has elapsed or the
doors are locked with the power lock switch or the
remote keyless entry transmitter. If a door is opened
during the illumination period, the timed illumination
will be canceled, and the interior lamps will remain on
since a 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 only four transmitters
matched to it.
If you prefer, you can complete this procedure yourself.
See ªVehicle Customization Settingsº in the Index for
more information.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three 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.

2-16 Trunk Release Sensor TrapAlert
System
(If Equipped)
Your vehicle may have a sensor located on the underside
of the filler panel inside the trunk.The sensor is designed to open the trunk automatically.
If the sensor detects motion and a difference in
temperature in the trunk, the sensor will sound the horn
if the ignition is in OFF. There will be three short chirps
and a pause repeated for up to two minutes. After one
minute, the trunk latch will release. If the ignition is not
in OFF, the trunk latch will not release automatically
and the horn will not sound.
To cancel the horn alarm and automatically release the
trunk lid before two minutes are up, turn the ignition
to ON.
Do not cover the sensor with items you put into the
trunk or with add
-on accessory equipment. If the
sensor's field of view is blocked, it will not detect
motion and will not function properly.
Be sure to secure items in your trunk so that they
won't move around and cause the trunk to open.

2-19
Content Theft-Deterrent (Option)
Your vehicle may have the optional content
theft
-deterrent alarm system.
With this system, a light on the radio will flash.
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
flash 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 flash 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 flashes 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 flashing
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 flash slowly to let you know the system
is armed.

2-20 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 flashing 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 first time a remote UNLOCK command is
received, three flashes 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.

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 briefly 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
that works along with the warning lights and gages.
See ªDriver Information Centerº in the Index.
Safety Belt Reminder Light
When the key is turned to ON, a chime will come on
for about eight seconds to remind people to fasten
their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds,
then it will flash for about
55 seconds.
