CAUTION
. Do not allow the retractor to roll
up the seatbelt too quickly.
Otherwise, the metal tongue
plates may hit against the trim,
resulting in damaged trim.
. Have the seatbelt fully rolled up
so that the tongue plates are
neatly stored. A hanging tongue
plate can swing and hit against
the trim during driving, causing
damage to the trim.
& Seatbelt maintenanceTo clean the seatbelts, use a mild soap
and lukewarm water. Never bleach or dye
the belts because this could seriously
affect their strength.
Inspect the seatbelts and attachments
including the webbing and all hardware
periodically for cracks, cuts, gashes,
tears, damage, loose bolts or worn areas.
Replace the seatbelts even if only minor
damage is found.
CAUTION
. Keep the belts free of polishes,
oils, chemicals and particularly
battery acid.
. Never attempt to make modifica-
tions or changes that will prevent
the seatbelt from operating prop-
erly.
Front seatbelt pretensionersThe driver ’s and front passenger ’s seat-
belts have a seatbelt pretensioner. The
seatbelt pretensioners are designed to be
activated in the event of an accident
involving a moderate to severe frontal
collision.
The pretensioner sensor also serves as
the frontal SRS airbag sensor. If the
sensor detects a certain predetermined
amount of force during a frontal collision,
the front seatbelt is quickly drawn back in
by the retractor to take up the slack so that
the belt more effectively restrains the front
seat occupant.
When a seatbelt pretensioner is activated,
an operating noise will be heard and a

& Selecting audible signal op-
erationUsing an electronic chirp, the system will
give you an audible signal when the doors
lock and unlock. If desired, you may turn
the audible signal off.
Do the following to deactivate the audible
signal. You can also use the same steps
to restore the function.
1. Sit in the driver ’s seat and shut all
doors and the rear gate.
2. Hold down the REAR (UNLOCK) side
of the power door locking switch.
3. While holding down the REAR (UN-
LOCK) side of the power door locking
switch, pull the key out and re-insert it into
the ignition switch at least 6 times within
10 seconds after Step 2.
4. Open and close the driver ’s door once
within 10 seconds after Step 3.
5. The turn signal lights flash 3 times to
indicate completion of the setting.
You may have the above settings done by
your SUBARU dealer. Also, for models
with the genuine SUBARU navigation
system, the setting can be changed using
the navigation monitor. For details, please
refer to the Owner ’s Manual supplement
for the navigation system.
& Replacing the battery
CAUTION
. Do not let dust, oil or water get on
or in the transmitter when repla-
cing the battery.
. Be careful not to damage the
printed circuit board in the trans-
mitter when replacing the battery.
. Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them.
. There is a danger of explosion if
an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
. Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
When the transmitter battery begins to get
weak, transmitter range will begin to
decrease. Replace the battery as soon
as possible. To replace the battery:
1. Open the transmitter case using a flat-
head screwdriver.2. Remove the old battery from the
holder.

finished.
. Setting the speed is impossible
when the vehicle is moving.
. The set engine speed may differ
from the engine speed shown by the
tachometer. Use the engine speed
shown by the tachometer as a rough
guide.
. If the setting operation is performed
with the engine switch turned off, the
REV indicator light turns off and the
setting operation is aborted when you
have stopped the setting operation for
approximately 10 seconds.

set the thousands place of the alarm-level
engine speed to “–”.
Warning and indicator lightsSeveral of the warning and indicator lights
illuminate momentarily and then turn off
when the ignition switch is initially turned
to the “ON”position. This permits check-
ing the operation of the bulbs.
Apply the parking brake and turn the
ignition switch to the “ON”position. For
the system check, the following lights
illuminate and turn off after several sec-
onds or after the engine has started:: Seatbelt warning light (The seatbelt warning light turns off

approximately 2 seconds when the igni-
tion switch is turned to the “ON”position.
After that, this indicator light/warning light
changes to BLUEand maintains illumina-
tion in BLUE. This BLUEilluminated light
turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature in-
creases over the specified range, the
indicator light/warning light blinks in
RED . At this time, the engine is close to
overheating.
If the engine coolant temperature in-
creases further, the indicator light/warning
light illuminates in REDcontinuously. At
this time, the engine may be overheating.
When the indicator light/warning light
blinks in REDor illuminates in RED, safely
stop the vehicle as soon as possible, and
refer to the emergency steps to take in the
case of engine overheating. Refer to
“Engine overheating ”F 9-13. After that,
have the system checked by your nearest
SUBARU dealer.
Also, if the indicator light/warning light
often blinks in RED, the electrical system
may be malfunctioning. Contact your
SUBARU dealer for an inspection.
NOTEIf the engine is restarted after a certain
driving condition, this indicator light/
warning light may illuminate in RED.
However, this is not a malfunction if the
indicator light/warning light turns off
after a short time.&
Charge warning light
If this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off 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
condition but the light remains illuminated,
contact your nearest SUBARU dealer
immediately.&
Oil pressure warning
light
If this light illuminates 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 illuminates while driving or does
not turn off 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 is
at the proper level but the light remains
illuminated, contact your nearest
SUBARU dealer immediately.
For details about checking the engine oil
level or adding the engine oil, refer to
“Engine oil
”F 11-10.
CAUTION
Do not operate the engine with the
oil pressure warning light illumi-
nated. This may cause serious en-
gine damage.&
AT OIL TEMP warning
light (AT models)
If this light illuminates when the engine is
running, it may indicate that the automatic
transmission fluid temperature is too hot.
If the light illuminates while driving, im-
mediately stop the vehicle in a safe place
and let the engine idle until the warning
light turns off.
! Automatic transmission control
system warning
If the “AT OIL TEMP ”warning light flashes
after the engine starts, it may indicate that
the automatic transmission control system

Black plate (141,1)

is not working properly. Contact your
nearest SUBARU dealer for service im-
mediately.&
Rear differential oil
temperature warning
light (STI)
CAUTION
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
illuminates. Continued driving with
this light illuminated can damage
the rear differential and other parts
of the powertrain.
If this light illuminates when the engine is
running, it may indicate that the rear
differential oil temperature is too hot.
At this time, the driver ’s control center
differential will automatically cancel the
current torque-distribution ratio setting and
adopt its minimum ratio.
If the light illuminates while driving, reduce
vehicle speed and stop the vehicle at the
nearest safe place. Park the vehicle for
several minutes. After the light turns off,
you can start driving.
If the light does not turn off, contact the
nearest SUBARU dealer for service.
NOTE. If the tire pressures are not correct
and/or the tires are not all the same
size and brand, the rear differential will
be heavily loaded when the vehicle is
driven, resulting in an abnormally high
oil temperature.
. The rear differential oil will deterio-
rate if its temperature increases en-
ough for the rear differential oil tem-
perature warning light to illuminate. It is
advisable to have the rear differential
oil replaced as soon as possible.&
Low tire pressure
warning light (U.S.-spec.
models)
When the ignition switch is turned to the
“ON ”position, the low tire pressure warn-
ing light will illuminate for approximately 2
seconds to check that the tire pressure
monitoring system (TPMS) is functioning
properly. If there is no problem and all tires
are properly inflated, the light will turn off.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle
’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver ’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,

properly and become damaged, the sys-
tem may not be able to control the interior
temperature correctly. To avoid damaging
the sensors, observe the following pre-
cautions.
– Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows.
– Solar sensor: beside the windshield
defroster grille.
– Interior air temperature sensor: near
the ignition switch.
– Outside temperature sensor: behind
the front grille.
Operating tips for heater and
air conditioner& Cleaning ventilation grilleAlways keep the front ventilation inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept clean
because cooling performance is impaired
by any accumulation of insects and leaves
on the condenser.&Efficient cooling after parking
in direct sunlightAfter parking in direct sunlight, drive with
the windows open for a few minutes to
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
efficiency.
&
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 indicate
any problem with the air conditioning
