GMC Acadia 2011 Owner's Manual page 44

2-14 Keys, Doors and Windows
If the delayed locking feature is
active, the alarm is not activated
until all doors are closed and the
security light goes off.
Press when the driver door
is closed. The security light
comes on solid for approximately
30 seconds and then goes off.
The content theft deterrent alarm
is not armed until the security
light goes off.
The theft-deterrent system will not
activate if the doors are locked with
the vehicle's key or the manual
door lock.
If a locked door is opened without
using the RKE transmitter, a
ten second pre-alarm occurs.
The horn chirps and the lights
flash. If the key is not placed in
the ignition and turned to START
or the door is not unlocked by
pressing during the ten second
pre-alarm, the alarm goes off.
The headlamps flash and the horn
sounds for about 30 seconds, then
turns off to save the battery power.
The vehicle can be started with the
correct ignition key if the alarm has
been set off.
To avoid setting off the alarm by
accident:
Lock the vehicle with the door
key after the doors are closed.
Unlock the door with the RKE
transmitter. Unlocking a door any
other way sets off the alarm if
the system has been armed.
Press or place the key in the
ignition and turn it to START to turn
off the alarm.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lower
the driver side window and open
the driver door.
2. Press .
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.
If the alarm does not sound when it
should, but the vehicle's headlamps
flash, check to see if the horn
works. The horn fuse may be blown.
To replace the fuse, see Fuses and
Circuit Breakers on page 10 33.
If the alarm does not sound or the
vehicle's headlamps do not flash,
see your dealer for service.
