6.  Briefly press the arm button (for less than 2 seconds). All doors (and the rear gate (Outback)) will lock, an electronic chirp will sound once, the hazard warning flashers will flash once, and the security indicator light will start flashing rapidly.

   After rapid flashing for 30 seconds (standby time), the security indicator light will then flash slowly (twice approximately every 2 seconds), indicating that the system has been armed for surveillance.

   If any of the doors (rear gate or trunk lid) is not fully closed, an electronic chirp sounds five times, the hazard warning flashers flash five times to alert you that the doors (or the rear gate/trunk lid) are not properly closed. When you close the door, the system will automatically arm and doors will automatically lock.
