Other information:
Your remote engine starter fob is a
bidirectional transceiver that can confirm
system operation with several different
visual and audible indications. The fob’s
LED-backlit button and internal piezo
buzzer will indicate status of the system
using the following flash and beep sequences,
provided the fob is within operational
range of the system...
CAUTION
If the CHECK ENGINE warning light/
Malfunction indicator light illuminates
while you are driving, have
your vehicle checked/repaired by
your SUBARU dealer as soon as
possible. Continued vehicle operation
without having the emission
control system checked and repaired
as necessary could cause
serious damage, which may not be
covered by your vehicle’s warranty...
