Arming The System - GMC YUKON DENALI 2000 Manual

-
Using a small flat tipped screwdriver, turn the
adjuster clockwise to increase sensitivity and turn
counterclockwise to decrease sensitivity. The shock
sensor is ignored by the alarm system when the ignition
is on, when the tailgate or panel doors are open, when
the alarm is disarmed, when customized to be ignored
and for five seconds after the horn sounds an alarm or
chirp. The shock sensor is ignored after triggering three
full alarms until the system is rearmed.

Arming the System

The alarm system can be armed to detect break
locking your vehicle using the keyless entry or by
locking the doors with the power door lock switch.
Passive arming is also available if you would like the
system to arm all by itself after the doors have been
closed for a short time. See "Feature Customization" in
the Index. When the system is armed, a red light will
flash on the center floor console briefly once every two
seconds. If you return to your vehicle and the red light is
flashing two brief flashes every two seconds, the system
is armed and the shock sensor had triggered a two
minute alarm. If the red light is flashing three times
every two seconds, the system is armed and there was an
intrusion that sounded the alarm.
Horn chirps and parking lamp flashes can be set to
your choice.
Remote Keyless Entry Transmitter Locking
If all the doors are closed, locking the vehicle with the
transmitter will immediately arm the system. The horn
will chirp twice and the headlamps and parking lamps
will flash, confirming that the system is armed if that
mode is selected. If any door is open when the
transmitter LOCK button is pressed, the system goes
into an armed wait mode, waiting for the doors to close.
Once they are closed, the system will arm and the
headlamps and parking lamps will flash. If the tailgate
or panel doors are open or ajar at the time the system is
-
ins by
arming, the headlamps and parking lamps flash once.
Power Door Lock Switch Locking
If any door is open when the power door lock switch is
pressed, the system goes into an armed wait mode,
waiting for the doors to close. Once they are closed, the
system will arm and the parking lamps will flash. If both
of the doors are closed when the power lock switch is
pressed, the system assumes you are inside the vehicle,
so it will not arm. Locking the doors by using the
manual door locks will not arm the system.
