B Starter interrupt
Starter interrupt is an automatic procedure. The starter is disabled
any time the system is armed, or if the Passive starter interrupt fea-
ture is enabled and the passive arm time is expired. The vehicle also
will not start if power is disconnected from the alarm module.
How starter interrupt works
The alarm system interrupts the signal from the ignition key to the ve-
hicle's starter when Starter interrupt is activated. If you attempt to start
the vehicle, the dash indicator will turn on as usual, but the starter will
not "crank", or turn over.
Passive starter interrupt
If the Passive Starter Interrupt option has been activated by your
SUBARU dealer, the starter will be automatically disabled one minute
after you turn off the vehicle ignition, whether or not you arm the secu-
rity system with your remote transmitter.

return. To enable the vehicle to start, simply press "UNLOCK" on
