!Tripped sensor identification
The security indicator light flashes when
the alarm system has been triggered. Also,
the number of flashes indicates the loca-
tion of unauthorized intrusion or the
severity of impact on the vehicle.
After turning the ignition switch to the“ON”
position, the indicator light will light for 1
second and then flash as follows.
.When a door was opened: 5 times
.When the trunk was opened: 4 times
.When the engine hood was opened: 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))NOTEAny 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 option)
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 approxi-
mately 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 vibra-
tion as indicated in the following ex-
amples 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.

The design of the push-button ignition
switch may be slightly different depending
on the models.
WARNING
.Before leaving the vehicle, ob-
serve the following instructions
for safety.
–Remove the key from the igni-
tion switch (models with con-
ventional type ignition
switch).
–Carry out the access key fob
(models with push-button
ignition switch).
–Never allow an unattended
child to remain in the vehicle.
Failure to observe these instruc-
tions could result in injury to a
child or others. Children could
operate the power windows, the
moonroof or other controls, or
even make the vehicle move.
.Never turn the ignition switch to
the“LOCK”/“OFF”position while
driving or being towed. Doing so
will lock the steering wheel, pre-
venting steering control. In addi-
tion, when the engine stops, it
takes a much greater effort thanusual to steer.
CAUTION
.To prevent the vehicle battery
from discharging, keep the igni-
tion switch in the“LOCK”/“OFF”
position when the engine is not
running.
.Do not use electrical accessories
for a long time with the ignition
switch in the“ON”or“ACC”
position. Doing so can cause the
battery to go dead.
