&Tripped sensor identification
The security indicator light flashes when
the alarm system has been triggered.
Also, the number of flashes indicates the
location of unauthorized intrusion or the
severity of impact on the vehicle.
When the ignition switch is turned to the
“ON ”position, the indicator light will light
for 1 second and then flash as follows.
. When a door or the rear gate (5-door)
was opened: 5 times
. When a door or the trunk (4-door) was
opened: 4 times
. When the ignition switch was turned to
the “ON ”position: 3 times
. When a strong impact or multiple
impacts were sensed: twice (only models
with shock sensors (dealer option))
. When a light impact was sensed: once
(only models with shock sensors (dealer
option))
NOTE
Any of the above indicator light flash-
ings will recur each time the ignition
switch is turned to the “ON”position.
Rearming the alarm system cancels the
flashing.
& Shock sensors (dealer op-
tion)
The shock sensors trigger the alarm
system when they sense impacts applied
to the vehicle and when any of their
electric wires are cut. The alarm system
causes the horn to sound and the hazard
warning flashers to flash for a short time
when the sensed impact is weak, but it
warns of a strong impact or multiple
impacts by sounding the horn and flashing
the hazard warning flashers, both lasting
approximately 30 seconds.
If you desire, your SUBARU dealer can
connect them and set them for activation
or deactivation.
NOTE
. The shock sensors are not always
able to sense impacts caused by break-
ing in, and cannot sense an impact that
does not cause vibration (such as
breaking the glass using a rescue
hammer).
. The shock sensors may sense vi-
bration as indicated in the following
examples and trigger the alarm system.
Select the settings of the alarm system
and shock sensors appropriately de-
pending on where you usually park
your vehicle. Examples:
–Vibration from a construction site
– Vibration in a multistory car park
– Vibration from trains
. You can have the sensitivity of the
shock sensors adjusted to your pre-
ference by your SUBARU dealer.
