Seat, seatbelt and SRS airbags1

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 maintenance
To 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 pretensioners
The 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 frontalcollision.
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 Seat, seatbelt and SRS airbags

switch is in the“ON ”position.
*3: Turbo models except STI
! Odometer
The odometer shows the total distance
that the vehicle has been driven. !
Double trip meter
The trip meter shows the distance that the
vehicle has been driven since you last set
it to zero.
To set the trip meter to zero, select the A
trip or B trip meter by pushing the knob
and keep the knob pushed for more than 2seconds.
CAUTION
To ensure safety, do not attempt to
change the function of the indicator
during driving, as an accident couldresult.
NOTE
If the connection between the combina- tion meter and battery is broken for any
reason such as vehicle maintenance or
fuse replacement, the data recorded on
the trip meter will be lost. &
Tachometer
The tachometer shows the engine speed
in thousands of revolutions per minute.
CAUTION
Do not operate the engine with the
pointer of the tachometer in the red
zone. This may cause severe da-
mage to the engine.
NOTE
For non-turbo models, to protect the
engine while the select lever is in the“ P ” or “N ” position (for AT models) or
the shift lever is in the neutral position
(for MT models), the engine is con-
trolled so that the engine speed may
not become too high even if the accel-
erator pedal is depressed hard. Instruments and controls

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 thosetires.)
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, Instruments and controls

light illuminates, have the vehicle
inspected at an authorized SUBARU
dealer.
! Hill start assist OFF indicator light(STI)
While the Hill start assist system is
deactivated, the Hill start assist OFF
indicator light illuminates continuously to
inform the driver that the Hill start assist
system is not operational. & Door open warning light
The door open warning light illuminates if
any door or the rear gate is not fullyclosed.
Always make sure this light is not illumi-
nated before you start to drive. &All-Wheel Drive warn-
ing light (AT models)
This light illuminates when All-Wheel
Drive is disengaged and the drive me-
chanism is switched to Front Wheel Drive
for maintenance or similar purposes.
It flashes if the vehicle is driven with tires
of differing diameters fitted on the wheels
or with an excessively low air pressure in
any of the tires.
CAUTION
Continuing to drive with the AWD
warning light flashing can damage
the powertrain. If the AWD warning
light starts to flash, promptly park in
a safe place and check whether the
tires have differing diameters and
whether any of the tires has an
excessively low inflation pressure.
& Vehicle Dynamics
Control operation indi-
cator light
It blinks when the skid suppression func-
tion is activated. It illuminates only when
the traction control function is operating.
The Vehicle Dynamics Control system is
probably malfunctioning under any of the
following conditions. Have your vehicle
checked at a SUBARU dealer immedi-
ately. .The light does not illuminate when the
ignition switch is turned to the “ON ”
position.. The light does not turn off even after a
period of approximately 2 seconds after
the ignition switch has been turned to the“ ON ”position. &
Vehicle Dynamics
Control warning light/
Vehicle Dynamics Con-
trol OFF indicator light/
Traction Control OFF in-
dicator light (STI)
This warning light has both the function of
indicating malfunctions in the Vehicle
Dynamics Control system and the function
of indicating that the Vehicle Dynamics
Control system has been deactivated or
only the Traction Control system has beendeactivated.
It illuminates in the event of a malfunction
in the system and is on when the Vehicle
Dynamics Control system is not operating
or only the Traction Control system is notoperating. STI:
This warning light illuminates in yellow for
approximately 1 second when the ignition
switch is turned to the “ON ”position. After
that, this warning light changes to green
and remains illuminated in green for 1
second, and then turns off. It indicates that
the Vehicle Dynamics Control system is
operating normally. Instruments and controls
