switch, pressing the remote entry transmitter
LOCK button or pressing the last two buttons
(7/8, 9/0) of the keyless entry keypad.
The alarm indicator will now glow steadily.
4. Close all doors. The alarm indicator light will
then remain on steadily for approximately 30
more seconds and then go out. When the light
goes out the system is armed.
NOTE: Be sure to close all doors completely. If
not, the alarm indicator light will remain on.
Remember, your anti-theft system is armed only
after the alarm indicator light remains on steadily
for approximately 30 seconds after the last door is
closed, and then goes out.
You can also arm the anti-theft system with the
factory installed remote entry system or the keyless
entry system by following this sequence:
1. Remove the key from the ignition.
2. Close all of the doors.
3. Press the remote entry transmitter LOCK
button or press the last two buttons (7/8, 9/0)
of the keyless entry keypad to lock the doors.
The alarm indicator will come on for 30
seconds to show the alarm is arming and then
turn off to show that the alarm has armed.
The anti-theft system is designed to work with the
factory installed remote entry system. It may not
work with other remote entry systems.
NOTE: The anti-theft system will not activate while
someone is sitting in the driver's seat or if there is
a heavy object in the driver's seat.
