Immobilizer (Turbo models)
The immobilizer system is designed to
prevent an unauthorized person from
starting the engine. Only keys registered
with your vehicle ’s immobilizer system
can be used to operate your vehicle. Even
if an unregistered key fits into the ignition
switch and can be turned to the “START ”
position, the engine will automatically stop
after several seconds.
Each immobilizer key contains a tran-
sponder in which the key ’s ID code is
stored. When a key is inserted into the ig-
nition switch and turned to the “ON ” posi-
tion, the transponder transmits the key ’s
ID code to the immobilizer system ’s re-
ceiver. If the transmitted ID code matches
the ID code registered in the immobilizer
system, the system allows the engine to
be started. Since the ID code is transmit-
ted and acted upon almost instantly, the
immobilizer system does not impede nor-
mal starting of the engine.
If the engine fails to start, pull out the key
once before trying again. (Refer to the “Ig-
nition switch ” section [chapter 3].)
This device complies with Part 15 of
the FCC Rules and with RSS-210 of In-
dustry Canada. Operation is subject to

SRS airbag system
warning light
When the ignition switch is turned to the “ON ” position, the SRS airbag system
warning light will come on for approxi-
mately six seconds and go out. This
shows the SRS airbag and SRS side air-
bag (if equipped) and seatbelt pretension-
ers are in normal operation.
Front passenger ’s frontal air-
bag ON and OFF indicators
: Front passenger ’s frontal airbag
ON indicator
: Front passenger ’s frontal airbag
OFF indicator
The front passenger ’s frontal airbag ON
and OFF indicators show you the status of
the front passenger ’s SRS frontal airbag.
The indicators are located next to the
clock in the center portion of the dash-
board. When the ignition switch is turned to the“
ON ” position, both the ON and OFF indi-
cators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators ex-
tinguish for 2 seconds. After that, one of
the indicators illuminates depending on
the status of the front passenger ’s SRS
frontal airbag determined by the Subaru
advanced frontal airbag system monitor-
ing.
If the front passenger ’s SRS frontal airbag
is activated, the passenger ’s frontal airbag
ON indicator will illuminate while the OFF
indicator will remain extinguished.
If the front passenger ’s SRS frontal airbag
is deactivated, the passenger ’s frontal air-
bag ON indicator will remain extinguished
while the OFF indicator will illuminate.
With the ignition switch turned to the “ON ”
position, if both the ON and OFF indica-
tors remain lit or extinguished simulta-
neously even after the system check peri-
od, the system is faulty. Contact your
SUBARU dealer immediately for an in-
spection.
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
to your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbag will not operate properly in
the event of a collision, which may
increase the risk of injury.

CHECK ENGINE warn-
ing light/Malfunction in-
dicator lamp
If this light comes on steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential prob-
lem somewhere in the emission control
system.
If the light comes on steadily:
If the light comes on steadily while driving
or does not go out after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately.
NOTE
This light also comes on when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator lamp coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light turn off immediately. It may
take several driving trips. If the light does
not go out, take your vehicle to your au-
thorized SUBARU dealer immediately.
If the light is blinking:
If the light is blinking while driving, an en-
gine misfire condition has been detected
which may damage the emission control
system.
To prevent serious damage to the emis-
sion control system, you should do the fol-
lowing.
Reduce vehicle speed.
Avoid hard acceleration.
Avoid steep uphill grades.
Reduce the amount of cargo, if possi-
ble.
Stop towing a trailer as soon as pos-
sible. The CHECK ENGINE warning light may
stop blinking and come on steadily after
several driving trips. You should have
your vehicle checked by an authorized
SUBARU dealer immediately.
Charge warning light
If this light comes on when the engine is
running, it may indicate that the charging
system is not working properly.
If the light comes on while driving or does
not go out after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good con-
dition but the light remains on, contact
your nearest SUBARU dealer immediate-
ly.
Oil pressure warning
light
If this light comes on when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system
is not working properly.
If the light comes on while driving or does
not go out after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil
If the CHECK ENGINE light comes
on while you are driving, have your
vehicle checked/repaired by your
SUBARU dealer as soon as possi-
ble. 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.

3-18 Instruments and controls
With a vehicle equipped with an EBD sys-
tem, the ABS warning light comes on to-
gether with the brake system warning light
if the EBD system becomes faulty. For fur-
ther details of the EBD system fault warn-
ing, refer to “Brake system warning light ”.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal.
The warning light comes on right af-
ter the engine is started but goes out
immediately, remaining off.
The warning light remains on after the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).
The warning light comes on during
driving, but it goes out immediately
and remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.
Brake system
warning light
This light has the following three func-
tions:
Parking brake warning
The light comes on with the parking brake
applied while the ignition switch is in the “ ON ” position. It goes out when the park-
ing brake is fully released.
Brake fluid level warning
This light comes on when the brake fluid
level has dropped to near the “MIN ” level
of the brake fluid reservoir with the ignition
switch in the “ON ” position and with the
parking brake fully released.
If the brake system warning light should
come on while driving (with the parking
brake fully released and with the ignition
switch positioned in “ON ”), it could be an
indication of leaking of brake fluid or worn
brake pads. If this occurs, immediately
stop the vehicle at the nearest safe place
and check the brake fluid level. If the fluid
level is below the “MIN ” mark in the reser-
voir, do not drive the vehicle. Have the ve-
hicle towed to the nearest SUBARU deal-
er for repair.
Electronic Brake Force Distribution
(EBD) system warning (vehicles
with ABS)
The brake system warning light also illu-
The warning light does not come
on when the ignition switch is
turned to the “ON ” position.
The warning light comes on when
the ignition switch is turned to the “ON ” position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12
km/h).
The warning light comes on dur-
ing driving.
If any of these conditions occur,
have the ABS system repaired at the
first available opportunity by your
SUBARU dealer.
Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.
