!Unfastening the seatbelt
1. Push the button on the buckle.
2. Allow the seatbelt to retract slowly to
avoid the seatbelt being tangled or twisted.
Before closing the door, make sure that the
belts are retracted properly to avoid
catching the belt webbing in the door.
&Seatbelt maintenanceTo clean the seatbelts, use lukewarm
water with mild soap. Do not use the
seatbelts until they are dry. 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. Re-
place 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 following seatbelts have a seatbelt
pretensioner.
.Driver’s seatbelt
.Front passenger’s seatbelt
The seatbelt pretensioners are designed
to be activated in the event of an accident
involving a moderate to severe frontal and
side collision and rollover accident.
WARNING
.To obtain maximum protection,
the occupants should sit in an
upright position with their seat-
belts properly fastened. Refer to
“Seatbelts”F1-12.
.Do not modify, remove or strike
the front seatbelt retractor as-
semblies or surrounding area.
This could result in accidental
activation of the seatbelt preten-
sioners or could make the system
inoperative, possibly resulting in
serious injury. Seatbelt preten-
sioners have no user-serviceable
parts. For required servicing of
front seatbelt retractors
equipped with seatbelt preten-
sioners, consult your SUBARU

.The camera unit is a waterproof
structure. Do not attempt to re-
move, disassemble or modify the
unit.
.Do not rub strongly or polish the
camera lens with a hard brush or
abrasive compounds. The lens
may be scratched resulting in an
adverse effect to the camera
image.
.The camera lens is made of glass
or plastic. Do not allow any
organic solvent, body wax, oil
film remover or glass coating
agent to become attached on the
lens surface. If any becomes
attached, remove it immediately.
.Do not expose the camera lens to
any sudden temperature change,
for example, spraying hot water
on it in cold weather.
.Do not apply the water jet of a
high pressure washer to the cam-
era or the surrounding area when
cleaning the vehicle. The impact
by the strong water pressure may
cause the camera to come off.
Also, water may enter inside the
camera and cause a malfunction.
.If the camera is exposed to any
impact, it may lead to malfunctionof the camera. Have the camera
inspected by your SUBARU deal-
er as soon as possible.
.Do not use a steam cleaner under
any circumstances. Some types
of steam cleaners inject hot
steam.
.The camera surface may be da-
maged by a flying stone.
NOTEIf the camera lens is contaminated, no
sharp image is available. When the
camera is contaminated with water
drops, snow or mud, wash it with water

CAUTION
.All the indicators will flash in the
event that the driver’scontrol
center differential has a malfunc-
tion. Have the vehicle inspected
by your SUBARU dealer.
.If a malfunction occurs in the
vehicle (for example, when the
rear differential oil temperature
warning light illuminates), all of
the indicators may disappear and
the setting value for the initial
limited slip differential (LSD) tor-
que of the driver’s control center
differential (C.DIFF/DCCD) may
be cancelled. However, it does
not indicate a malfunction of the
C.DIFF/DCCD itself.
The driver’s control center differential
allows you to freely change the degree of
limitation of the differential action (limited
slip differential (LSD) torque) of your
vehicle’s center differential.
By using the center differential control
switch, you can set an initial LSD torque
to match the road surface conditions,
driving conditions and your driving style.The driver’s control center differential has
the following modes.
.Auto mode: the system automatically
adjusts the initial LSD torque.
.Manual mode: you can change to the
desired mode manually by using the
center differential control switch.
NOTEIf you rapidly depress and release the
accelerator pedal while driving at low
speed, you may hear a knocking sound
from the vicinity of the center differen-
tial and rear differential. This sound
occurs because of the structure of the
center differential. It does not indicate a
problem.
&To change mode of driver’s
control center differentialPress the“AUTO-MANU”switch on the
center console to switch from auto mode to
manual mode or vice versa. When you
select the auto mode, the“AUTO”indicator
appears. When you select the manual
mode, the“AUTO”indicator disappears.

1) Upshift indicator
2) Downshift indicator
3) Gear position indicatorWhen the manual mode is selected, the
gear position indicator and upshift indica-
tor and/or downshift indicator on the
combination meter appear.
The gear position indicator shows the
currently selected gear in the following
range.
.1st-to-8th-gear range (when the Sport
Sharp (S#) mode is selected)
.1st-to-6th-gear range (in other situa-
tions)
The upshift and downshift indicators show
when a gear shift is possible. When the
upshift indicator“
”appears, upshifting is
possible. When the downshift indicator“
”appears, downshifting is possible.
When both indicators appear, upshifting
and downshifting are both possible. When
the vehicle stops (for example, at traffic
signals), the downshift indicator turns off.
Gearshifts can be performed using the
shift paddle behind the steering wheel.
To upshift to the next higher gear position,
pull the shift paddle that has“+”indicated
on it. To downshift to the next lower gear
position, pull the shift paddle that has“–”
indicated on it.
CAUTION
Do not place or hang anything on the
shift paddles. Doing so may result in
accidental gear shifting.
NOTEPlease read the following points care-
fully and bear them in mind when using
the manual mode.
.If you attempt to shift down when the
engine speed is too high, i.e., when a
downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible.
.If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.
.You can perform a skip-shift (for
example, from 4th to 2nd) by operating
the shift paddle twice in rapid succes-
sion.
.The transmission automatically se-
lects 1st gear when the vehicle stops
moving.
.If the temperature of the transmis-
sion fluid becomes too high, the“AT
OIL TEMP”warning light on the combi-
nation meter will illuminate. Immedi-
ately stop the vehicle in a safe location
and let the engine idle until the warning
light turns off.
.By selecting the Sport Sharp (S#)
mode, upshifting will not occur auto-
matically. According to the road condi-
tions, shift change manually so that the
tachometer needle does not enter the

Engine oil
CAUTION
.If the level gauge is not pulled out
easily, twist the level gauge right
and left, then pull it out. Other-
wise, you may be injured acci-
dentally straining yourself.
.Use only engine oil with the
recommended grade and vis-
cosity.
.Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.&Engine oil consumptionSome engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the following conditions, oil
consumption can be increased and thus
require refilling between maintenance in-
tervals:
.When the engine is new and within the
break-in period.When the engine oil is of lower quality
.When the incorrect oil viscosity is used
.When engine braking is employed
(repeatedly)
.When the engine is operated at high
engine speeds (for extended periods of
time)
.When the engine is operated under
heavy loads (for extended periods of time)
.When the engine idles for extended
periods of time
.When the vehicle is operated in stop
and go and/or heavy traffic situations
.When the vehicle is used under severe
thermal conditions
.When the vehicle accelerates and
decelerates frequently
Under these or similar conditions, you
should check your oil at least every 2nd
fuel fill-up and change your engine oil more
frequently. Different drivers in the same
car may experience different results. If
your oil consumption rate is greater than
expected, contact your authorized
SUBARU retailer who may perform a test
under controlled conditions.
&Checking the oil level1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait a few
minutes for the oil to drain back into the oil
pan before checking the level.STI

CAUTION
.For models except STI, be careful
not to touch the engine oil filter
when removing the oil filler cap.
Doing so may result in a burn, a
pinched finger, or may cause
some other injury.
.Use only engine oil with the
recommended grade and vis-
cosity.
.Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is
correct.
For models STI, just after driving or while
the engine is warm, the engine oil level
reading may be in a range between the
upper level and the notch mark. This is
caused by thermal expansion of the
engine oil.
NOTETo prevent overfilling the engine oil, do
not add any additional oil above the
upper level when the engine is cold.&Changing the oil and oil filterChange the oil and oil filter according to
the maintenance schedule in the“War-
ranty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in
the maintenance schedule when driving
on dusty roads, when short trips are
frequently made, or when driving in ex-
tremely cold weather.NOTE.Changing the engine oil and oil filter
should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil filter.
Fully trained mechanics are on standby
at a SUBARU dealer to utilize the
special tools, spare parts and recom-
mended oil for this work, and also, used
oils are properly disposed of.
.If performing oil replacement your-
self, observe the local regulations and
dispose of waste oil properly.
&Recommended grade and
viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to“Engine oil”F12-4.NOTEEngine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. However,
in hot weather, oil of higher viscosity is
required to properly lubricate the en-
gine.

&Synthetic oilYou must follow the oil and filter changing
intervals shown in the Warranty and
Maintenance booklet.NOTESynthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.
Cooling system
WARNING
.Never attempt to remove the
radiator cap until the engine has
been shut off and has cooled
down completely. Since the cool-
ant is under pressure, you may
suffer serious burns from a spray
of boiling hot coolant when the
cap is removed.
.Be careful of the rotating cooling
fan when the engine hood is
open. When the engine tempera-
ture is high, the cooling fan in the
engine compartment may oper-
ate when the ignition switch is in
the“ON”position, even if the
engine is stopped. Touching the
cooling fan while it is rotating
may result in injury.
CAUTION
.Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). Do not mix
this coolant with any other brandor type of coolant during this
period. Mixing with a different
coolant will reduce the life of the
coolant. Should it be necessary
to top up the coolant for any
reason, use only SUBARU Super
Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
type, the maintenance interval is
shortened to that of the mixing
coolant.
.Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

Alloy wheelsAlloy wheels can be scratched and da-
maged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
.When any of the wheels are removed
and replaced for tire rotation or to change a
flat tire, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose,
tighten it to the specified torque.
.Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
.Never let the wheel rub against sharp
protrusions or curbs.
.When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for alloy wheels.
Windshield washer fluid
CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.Windshield washer fluid warning in-
dicator
When there is only a small amount of
washer fluid remaining, the windshield
washer fluid warning indicator will illumi-
nate. When this occurs, refill the washer
fluid as follows.
Remove the washer tank filler cap, then
add windshield washer fluid until it reaches
the“FULL”mark on the tank. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter, use
an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it is
diluted, as indicated in the following table.
