Arming the CTD System

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: The content theft deterrent (CTD) system can be armed with the windows or sunroof open.

Use the following procedure in order to arm the system:

Turn OFF the ignition.
Exit the vehicle.
IMPORTANT: The system is not armed if the doors are locked manually. The keyless entry transmitter or the door lock switch must be used to arm the CTD system.

With a vehicle door open, lock the doors by pressing the LOCK button on the keyless entry transmitter or by pressing the LOCK button on the door lock switch. The system will begin the arm sequence when all doors are closed. The CTD system transition to the arm delay state when the final door is closed. The security indicator will illuminate steady when in the arm delay state.

If the keyless entry transmitter LOCK button is pressed after the vehicle doors have been closed, the system will transition directly to the arm delay state with the indicator on steady.
The system will arm approximately 30 seconds from the time that the system has entered the arm delay state. When the security indicator transitions to flashing slowly, the system is armed.
Alternately, if the LOCK button on the keyless entry transmitter is pressed a second time, the system will arm immediately, bypassing the 30 second delay.
