2002 GMC SIERRA remote start

2-8
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 the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation

You can choose different feedback options for each
press of the UNLOCK button. See ªSecondary
Information Centerº in the Index for more information.

doors. You can choose different feedback options for
each press of the LOCK button. See ªSecondary
Information Centerº in the Index for more information.
Operating the keyless entry transmitter may interact
with the theft

Deterrentº and ªSecondary Information Centerº in the
Index for more information.

Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system. You can disable the system or personalize
it to suit your needs. See ªSecondary Information
Centerº in the Index for more information.
With this system,
the SECURITY message
on the cluster will flash
as you open the door
(if your ignition is off).
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
message 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 of the doors. The SECURITY message
should go off after approximately 15 seconds.
The alarm is not armed until the SECURITY
message 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 flash or both the headlamps
and the horn will activate. See ªSecondary Information
Centerº in the Index for more information.
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 flash, you may have the feature turned off.
See ªSecondary Information Centerº in the Index for
more information.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. Turn off all lamps
that aren't needed as well as radios. This will avoid
sparks and help save both batteries. In addition, it
could save your radio!4. Open the hoods and locate the positive (+) and
negative (
-) terminal locations on the other vehicle.
Your vehicle has a remote positive (+) jump starting
terminal and a remote negative (
-) jump starting
terminal. You should always use the remote
positive (+) and the remote negative (
-) terminals
instead of the positive (+) and negative (
-) terminals
on your battery. The remote positive (+) terminal is
located behind a red plastic cover near the engine
accessory drive bracket. To uncover the remote
positive (+) terminal, open the red plastic cover.
The remote negative (
-) terminal is located on the
engine accessory drive bracket. This is marked
ªGND.º See ªEngine Compartment Overviewº in
the Index for more information on location.

8. Now connect the black
negative (
-) cable to
the good battery's
negative (
-) terminal.
Use a remote
negative (
-) terminal if
the vehicle has one.
Don't let the other end touch anything until the next
step. The other end of the negative (
-) cable doesn't
go to the dead battery. It goes to a heavy, unpainted
metal engine part or to a remote negative (
-) terminal
on the vehicle with the dead battery.
9. Connect the other
end of the negative (
-)
cable to the remote
negative (
-) terminal,
marked GND, on the
vehicle with the dead
battery. If the THEFT
SYSTEM light flashes,
wait until the light stops
flashing before starting
the engine.
10. Now start the vehicle with the good battery and run
the engine for awhile.
11. Try to start the vehicle with the dead battery.
If it won't start after a few tries, it probably
needs service.
NOTICE:
Damage to your vehicle may result from electrical
shorting if jumper cables are removed incorrectly.
To prevent electrical shorting, take care that they
don't touch each other or any other metal. The
repairs wouldn't be covered by your warranty.
