2003 CADILLAC CTS alarm

Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
Because your vehicle has the theft
-deterrent system, you
must unlock the doors with the key or remote keyless
entry transmitter to avoid setting off the alarm. If the
windows are down and the doors are locked, don't reach
in to manually unlock the vehicle because you will set
off the alarm.
From the outside, use either the key or the remote
keyless entry transmitter.
From the inside, use
the manual lock levers
located on the door panels
near the windows.
Push down on the manual lock lever to lock the door.
To unlock the door, pull up on the lever.

(Unlock): When you press this symbol on the
remote keyless entry transmitter, the driver's door will
unlock. This also disarms the theft
-deterrent system.
Press the button again to unlock the rest of the doors.
You can program your vehicle so that the exterior lamps
will flash when you unlock the doors with the remote
keyless entry transmitter. See ªVehicle Programming
and Personalization Featuresº in the Index for more
information on programming this feature.
If your vehicle is programmed for remote confirmation,
the doors must be closed for this feature to work. If a
door is open, remote confirmation will be canceled.
(Panic Alarm): The remote keyless entry
transmitter comes equipped with an instant panic alarm.
To use the alarm, press the horn symbol when the
ignition is turned off. The horn will sound and the
exterior lamps will flash for up to 30 seconds. To stop
the instant panic alarm, press the symbol again or turn
the ignition to ON.
(Trunk): Press this button to open the trunk.
The remote keyless entry transmitter can be used to
recall the memory settings for up to two drivers. For
more information, see ªVehicle Programming and
Personalization Featuresº and ªMemory Seat and
Mirrorsº in the Index.
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.

Theft-Deterrent System
The security light is located
on the instrument panel
cluster.
If the ignition is off and a door is open, the security light
will flash, reminding you to arm the theft
-deterrent
system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the remote keyless entry
transmitter or the power door lock switch. The
security light should come on and stay on.
3. Close all the doors. The security light should go off
within approximately 30 seconds.
If a door or a trunk is opened without a key or a remote
keyless entry transmitter, the horn will sound and the
lamps will flash for up to 30 seconds.The theft
-deterrent system won't arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the remote keyless entry
transmitter.
To avoid activating the alarm by accident do the
following:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the remote
keyless entry transmitter. Pressing the unlock button
on the remote keyless entry transmitter disables the
theft
-deterrent system. Unlocking a door any other
way will activate the alarm when a door or the trunk
is opened.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter, or by starting the vehicle with a valid key.

Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock switch or the
remote keyless entry transmitter and close the door.
Wait approximately 30 seconds until the security
light goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
exterior lamps will flash.
You can turn off the alarm by unlocking the driver's
door with your key, using the unlock button on the
remote keyless entry transmitter or by starting the car
with a valid key.
If the alarm does not sound when it should, 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 fuse does not need to be replaced, you may
need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft
-deterrent system when leaving your vehicle.

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 also has a Driver Information Center (DIC)
that works along with the warning lights and gages. See
ªDriver Information Center (DIC)º later in this section
for more information.
