2007 GMC ENVOY DENALI alarm

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.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent
alarm system.
The security light is
located on the
instrument panel cluster.To operate the system, do the following:
1. Open the door.
2. Lock the door with the power door lock switch
or the Remote Keyless Entry (RKE)
transmitter. The security light should ash.
3. Close all doors. The security light should turn
off after about 30 seconds. The alarm is not
armed until the security light turns off.
If a locked door is opened without the key or
the RKE transmitter, the alarm will go off.
The headlamps and parking lamps will ash for
two minutes, and the horn will sound for
30 seconds, then will turn off to save the
battery power.
Remember, the theft-deterrent system will not
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 RKE transmitter. You should also remember
that you can start your vehicle with the correct
ignition key if the alarm has been set off.
110

To avoid setting off the alarm by accident, do the
following:
Always lock the vehicle using the door key
afterthe doors are closed.
Always unlock a door with a key, or use the
RKE transmitter. Unlocking a door any other
way will set off the alarm.
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 RKE transmitter.
The alarm will not stop if you try to unlock a door
any other way.
Testing the Alarm
To test the alarm, do the following:
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 RKE transmitter.
3. Get out of the vehicle, close the door and wait
for the security light 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.When the alarm is set the power door unlock
switch will not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 493.
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by
your dealer.
Passlock®
Your vehicle has the Passlock®theft-deterrent
system.
Passlock
®is a passive theft-deterrent system that
enables fuel if the ignition lock cylinder is turned
with a valid key. If a correct key is not used or the
ignition lock cylinder has been tampered with, the
fuel system is disabled and the vehicle will not start.
During normal operation, the security light will
turn off about ve seconds after the key is turned
to RUN.

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. 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 (DIC) that works along with the warning
lights and gages. SeeDriver Information
Center (DIC) on page 218.
