2004 GMC SIERRA DENALI alarm

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
·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 ªBattery Replacementº under
Remote Keyless Entry System Operation on
page 2-4.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.

Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light on the cluster
will ¯ash as you open
the door (if your ignition is
off), to let you know
that you are activating
the system.
This message 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 security
light should come on and ¯ash. If you are using the
remote keyless entry transmitter, the door does
not need to be open.
3. Close all of the doors. The light will stop ¯ashing and
stay solid.The security light should go off after
approximately 30 seconds. The alarm is not armed
until the security light goes off. If the delayed locking
feature is active, the alarm will not activate until all
doors are closed and the security light goes off.Once the system is armed, if a door is opened without
the key or the remote keyless entry transmitter, the
alarm will go off. Depending on how you have
programmed the alarm in the secondary information
center, the horn may sound, the headlamps may ¯ash
or both the headlamps and the horn will activate.
Remember, the theft-deterrent system won't activate if
you lock the doors with a key or use the manual
door lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key if
the alarm has been set off.
Here's how to avoid setting off the alarm by accident:
·If you don't want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
·Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm if the system
has been armed.
If you set off the alarm by accident, unlock any door with
the key. You can also turn off the alarm by pressing
UNLOCK on the remote keyless entry transmitter or by
placing the key in the ignition and turning it to START.

Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver's window
and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the security message to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound and the headlamps do not
¯ash, you may have the feature turned off. See
DIC
Operation and Displays on page 3-46for more
information.
Passlockž
Your vehicle is equipped with the
Passlockžtheft-deterrent system.
Passlock
žis a passive theft-deterrent system.
Passlockženables 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.
If the engine stalls and the security light ¯ashes,
wait until the light stops ¯ashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock
žsystem is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
žat this
time. You may also want to check the fuse. See
Fuses and Circuit Breakers on page 5-105. See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See
Roadside Assistance Program on page 7-6.

Warning Lights, Gages and
Indicators
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 brie¯y 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 system that
works along with the warning lights and gages. See
Driver Information Center (DIC) on page 3-46.
