: 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 indicator is displayed near the map
lights.
When the ignition switch is turned to the
“ON”position, both the ON and OFF
indicators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators turn
off for 2 seconds. After that, one of the
indicators illuminates depending on the
status of the front passenger’s SRS frontalairbag determined by the SUBARU ad-
vanced frontal airbag system monitoring.
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 off.
If the front passenger’s SRS frontal airbag
is deactivated, the passenger’s frontal
airbag ON indicator will remain off while
the OFF indicator will illuminate.
With the ignition switch turned to the“ON”
position, if both the ON and OFF indicators
remain illuminated or off simultaneously
even after the system check period, the
system is malfunctioning. Contact your
SUBARU dealer immediately for an in-
spection.

the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
If the light illuminates steadily after
blinking for approximately one min-
ute, promptly contact a SUBARU
dealer to have the system inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low pres-
sure threshold, the low tire pressure
warning light should turn off a few
minutes later. Therefore, be sure to
install the specified size for the frontand rear tires.
&ABS warning light
CAUTION
.If any of the following conditions
occur, we recommend that you
have the ABS repaired at the first
available opportunity by your
SUBARU dealer.
–The warning light does not
illuminate when the ignition
switch is turned to the“ON”
position.
–The warning light illuminates
when the ignition switch is
turned to the“ON”position,
but it does not turn off even
after the vehicle is started.
–The warning light illuminates
during driving.
.When the warning light is on (and
the brake system warning light is
off), the ABS function shuts
down. However, the conventional
brake system continues to oper-
ate normally.
The ABS warning light, Vehicle Dynamics
Control warning light, and brake systemwarning light illuminate simultaneously if
the EBD system malfunctions. For further
details of the EBD system malfunction
warning, refer to“Electronic Brake Force
Distribution (EBD) system warning”F3-
21.
NOTEIf the warning light behavior is as
described in the following conditions,
the ABS may be considered normal.
.The warning light illuminates when
the ignition switch is turned to the“ON”
position and turns off approximately 2
seconds after the engine has started.
.The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
.The warning light remains illumi-
nated after the engine has been started,
but it turns off while driving.
.The warning light illuminates during
driving, but it turns off immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction. When
the battery becomes fully charged, the
light will turn off.

&Brake system
warning light (red)This light illuminates with the parking
brake applied while the ignition switch is
in the“ON”position. It turns off when the
parking brake is fully released.
WARNING
.Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains illuminated,
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.
The brake system warning light has the
following functions.
!Brake fluid level warningThis light illuminates 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
illuminate 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
location and check the brake fluid level. If
the fluid level is below the“MIN”mark in
the reservoir, do not drive the vehicle.
Have the vehicle towed to the nearest
SUBARU dealer for repair.
!Electronic Brake Force Distribution
(EBD) system warning
The EBD system may be malfunctioning if
the brake system warning light
/
,
Vehicle Dynamics Control warning light
and ABS warning light
/
illuminate
simultaneously during driving.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.
If the brake system warning light
/
,
Vehicle Dynamics Control warning light
and ABS warning light
/
illuminate
simultaneously, take the following steps.
1. Stop the vehicle in the nearest safe, flatlocation.
2. Shut down the engine, apply the
parking brake and then restart it.
3. Fully release the parking brake.
4. Even if all the warning lights do not
come back on, the EBD system may have
a possible malfunction. Drive carefully to
the nearest SUBARU dealer and have the
system inspected.
5. If all the warning lights stay illuminated
or come back on after approximately 2
seconds, shut down the engine, apply the
parking brake and check the brake fluid
level.
.If the brake fluid level is not below the
“MIN”mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
.If the brake fluid level is below the“MIN”
mark, DO NOT drive the vehicle. Instead,
have the vehicle towed to the nearest
SUBARU dealer for repair.
!Vacuum pressure system warning
The brake system warning light
/
will
illuminate when the vacuum pressure
sensor is malfunctioning or brake booster
pressure is decreasing.

allow outside air to circulate into the
heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of the
air conditioner for maximum cooling effi-
ciency.&Lubrication oil circulation in
the refrigerant circuitOperate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil.&Checking air conditioning
system before summer sea-
sonCheck the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer.&Cooling and dehumidifying in
high humidity and low tem-
perature weather conditionsUnder certain weather conditions (high
relative humidity, low temperatures, etc.) a
small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicateany problem with the air conditioning
system.
&Air conditioner compressor
shut-off when engine is
heavily loadedTo improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steep
upgrade.&Refrigerant for your climate
control systemYour air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od of adding, changing or checking the
refrigerant is different from the method for
CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are not
covered under warranty.
Air filtration systemYour vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the cabin air filter according to
the replacement schedule found in the
“Warranty and Maintenance Booklet”. This
schedule should be followed to maintain
the filter’s dust collection ability. Under
extremely dusty conditions, the filter
should be replaced more frequently. Have
your filter checked or replaced by your
SUBARU dealer. For replacement, use
only a genuine SUBARU air filter kit.
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter:
.Reduction of the airflow through
the vents.
.Windshield gets easily fogged or
misted.NOTEThe filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.
