Use the following procedure in order to arm the system:

1. Place the shift lever in P (park).
2. Turn OFF the ignition.
3. Open any door.

Important: The system is not armed if the doors are locked manually, the power door lock switch or remote transmitter must be used in order to arm the CTD system.

4. Lock the doors with the power door lock switch or the LOCK button on the transmitter. The system is in standby mode and will not start the arming timer until all doors are closed.
5. The system will arm approximately 30 seconds from the time that the last door is closed. This delay is shown by the Security indicator ON STEADY. When the indicator transitions to OFF, the system is armed.

Locking the vehicle may be accomplished without arming the CTD system. Use of the manual door locks or using the key to lock the LF door will lock the vehicle, but will not arm the CTD system.

If system arming has been requested by the power door lock switch or the transmitter, it must be disarmed.

Important: Using the power door unlock switch or manually unlocking the doors does not disable the CTD alarm mode. Also, disconnecting the battery or pulling fuses does not disable the alarm mode, since the RFA stores the CTD mode status in EEPROM.

Use one of the following procedures in order to deactivate and disarm the CTD system in alarm mode (pulsing horn(s) and exterior lamps flashing):
