From the manual.
Ultrasonic Interior Protection
The interior protection system in the SUBARU Category 1 Alarm System employs a sophisticated microprocessor controlled ultrasonic method of detection. Unlike conventional ultrasonic detectors this method ensures that an actual entry has occurred rather than just air movement, air pressure fluctuation, seat belt movement, etc.
Whenever the system is armed:
Initially the dashboard LED flashes dimly for the first 15 seconds. During this period the ultrasonic sensors are inactive. This allows the air movement inside the vehicle to stabilise.
The dashboard LED will then flash brightly for the next 15 seconds. The ultrasonic sensors are now active. The alarm system's microprocessor monitors the interior of the vehicle, and will reduce the sensitivity (from the maximum sensitivity programmed by the installer) if any background movement is detected that would cause a false alarm (if excess movement is detected during this period the LED will remain illuminated for a second, indicating that the sensitivity has been reduced).
After the first 32 seconds the dashboard LED will flash dimly again. The system is now fully armed and the ultrasonic sensitivity is set to the programmed maximum or the reduced level if some background movement was detected.
Sit in the car and keep still untill the LED flashes dimly then move, that should set it off. As far as adjusting the sensitivity manually though I can't help, sorry.
