2005 CADILLAC STS alarm

If you ever notice a decrease in the keyless access
transmitter range, try doing one of the following:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Keyless Access System Operation on page 2-4.
Check to make sure that an electronic device such
as a cellular phone or lap top computer is not
causing interference.
If you are still having trouble, see your dealer or a
qualied technician for service.
Keyless Access System Operation
Your vehicle has a Keyless Access System that lets you
lock and unlock your vehicle’s doors, open the trunk
lid, remotely start the engine, and locate your vehicle, or
sound your vehicle’s alarm from a distance as much
as much as 30 feet (10 m) away.
The Keyless Access System also lets you lock and
unlock the vehicle’s doors and access the trunk without
removing the remote transmitter from your pocket,
purse, briefcase, etc. The system operates when the
transmitter is located within 3 feet (1 m) of the door or
trunk of your vehicle. See “Keyless Doors Unlock”
and “Keyless Ft (Front) Door Unlock” underVehicle
Personalization on page 2-47.
Your vehicle comes with
two transmitters.

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.
Theft-Deterrent System
Your vehicle has a theft-deterrent alarm 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 ash, reminding you to arm the theft-deterrent
system.
To arm the system, do one of the following:
Press the lock button on the keyless access
transmitter. If the door is closed when the lock button
is pressed, the security light will stay illuminated for
30 seconds. After the security light goes off, the
theft-deterrent system is armed. Pressing the lock
button twice will arm the system immediately.If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open
or not closed completely, the security light will ash
for 60 seconds and then turn off. At this time, the
theft-deterrent system is armed but the alarm will not
sound if the trunk lid, hood or door that was not
closed completely is tampered with or opened. The
alarm will sound for the trunk lid, hood or a door that
was completely closed at the time the vehicle was
locked using the keyless access transmitter.
Open the door. Lock the door with the power door
lock switch or lock button on the keyless access
transmitter. The security light should ash. Close the
door. The security light will stop ashing and stay on.
After 30 seconds the light should turn off, the
theft-deterrent system is armed.
Passive Arming, if activated through the vehicle
personalization feature, will arm the system
automatically after you close the door and take at
least one keyless access transmitter with you. The
security light will turn on. After 60 seconds the light
should turn off. The theft-deterrent system is armed.
SeeVehicle Personalization on page 2-47.
If a door, hood, or the trunk is opened without the
keyless access transmitter, the horn will sound for
30 seconds and the lamps will ash for two minutes.
The vehicle cannot be started without a keyless access
transmitter.
2-19

The Theft-Deterrent system will not arm if:
The key is used to lock the driver’s door.
The driver’s door is locked using the power door
lock switch after the doors are closed.
If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open or
not closed completely, the security light will ash for
60 seconds and then turn off. At this time, the
theft-deterrent system is armed but the alarm will not
sound if the trunk lid, hood or door that was not closed
completely is tampered with or opened. The alarm
will sound for the trunk lid, hood or a door that was
completely closed at the time the vehicle was locked
using the keyless access transmitter.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft-deterrent system when
you approach the vehicle and the keyless access
transmitter is with you. SeeVehicle Personalization
on page 2-47.
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the driver’s door
disarms the theft-deterrent system. Unlocking a door
any other way while the system is armed will activate
the alarm.
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 keyless access transmitter and close the
door. Wait approximately 30 seconds until the
security light goes off.
3. Reach in and open the door using the inside door
handle. The horn will sound and the exterior lamps
will ash.
You can turn off the alarm by pressing the unlock
button on the keyless access transmitter or by starting
the car.
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, seeFuses and Circuit Breakers on
page 5-95. 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 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. 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.
SeeDriver Information Center (DIC) on page 3-73for
more information.
