General information
&California proposition 65
warning
WARNING
Engine exhaust, some of its consti-
tuents, and certain vehicle compo-
nents contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm. In addi-
tion, certain fluids in vehicles and
certain components of product wear
contain or emit chemicals known to
the State of California to cause
cancer and birth defects or other
reproductive harm.
&California Perchlorate Advi-
sory
Certain vehicle components such as air-
bag modules, seatbelt pretensioners and
keyless entry transmitter batteries may
contain perchlorate material. Special
handling may apply for service or vehicle
end of life disposal. See www.dtsc.ca.gov/
hazardouswaste/perchlorate.
&Noise from under the vehicle
NOTE
You may hear a noise from under the
vehicle approximately 5 to 10 hours
after the engine is turned off. However,
this does not indicate a malfunction.
This noise is caused by the operation
of the fuel evaporation leakage check-
ing system and the operation is normal.
The noise will stop after approximately
15 minutes.
&Event data recorder
This vehicle is equipped with an event
data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or
near crash-like situations, such as an air
bag deployment or hitting a road obstacle,
data that will assist in understanding how
a vehicle’s systems performed. The EDR
is designed to record data related to
vehicle dynamics and safety systems for
a short period of time, typically 30 seconds
or less. The EDR in this vehicle is
designed to record such data as:
.How various systems in your vehicle
were operating;
.Whether or not the driver and passen-
ger safety belts were buckled/fastened;
.How far (if at all) the driver was
depressing the accelerator and/or brakepedal; and,
.How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data are recorded by your vehicle
only if a non-trivial crash situation occurs;
no data are recorded by the EDR under
normal driving conditions and no personal
data (e.g., name, gender, age, and crash
location) are recorded. However, other
parties, such as law enforcement, could
combine the EDR data with the type of
personally identifying data routinely ac-
quired during a crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the
vehicle or the EDR is needed. In addition
to the vehicle manufacturer, other parties,
such as law enforcement, that have the
special equipment, can read the informa-
tion if they have access to the vehicle or
the EDR.

Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause damage to the
engine and/or fuel system.
&Fuel requirements
The engine is designed to operate using
unleaded gasolinewith an octane rating
of87 AKI (90 RON) or higher.
!Fuel octane rating
Using a gasoline with a lower octane
rating can cause persistent and heavy
knocking, which can damage the engine.
Do not be concerned if your vehicle
sometimes knocks lightly when you drive
up a hill or when you accelerate. See your
dealer or a qualified service technician if
you use a fuel with the specified octane
rating and your vehicle knocks heavily or
persistently.
!RON
This octane rating is the Research Octane
Number.!AKI
This octane rating is the average of the
Research Octane and Motor Octane
numbers and is commonly referred to as
the Anti Knock Index (AKI).
!Unleaded gasoline
The neck of the fuel filler pipe is designed
to accept only an unleaded gasoline filler
nozzle. Under no circumstances should
leaded gasoline be used because it will
damage the emission control system and
may impair driveability and fuel economy.
!California fuel
If your vehicle was certified to California
Emission Standards as indicated on the
underhood tune-up label, it is designed to
optimize engine and emission control
system performance with gasoline that
meets the clean burning low-sulfur Cali-
fornia gasoline specifications. If you live in
any other state than California, your
vehicle will operate on gasoline meeting
Federal specifications. Gasoline sold out-
side California is permitted to have higher
sulfur levels, which may affect the perfor-
mance of your vehicle’s catalytic converter
and may produce a sulfur exhaust odor or
smell. SUBARU recommends that you try
a different brand of unleaded gasoline
having lower sulfur to determine if the
problem is fuel related before returningyour vehicle to an authorized dealer for
service. The CHECK ENGINE warning
light/malfunction indicator light may also
turn on. If this occurs, return to your
authorized SUBARU dealer for diagnosis.
If it is determined that the condition is
caused by the type of fuel used, repairs
may not be covered by your warranty.
!MMT
Some gasoline contains an octane-en-
hancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl). If
you use such fuels, your emission control
system performance may deteriorate and
the CHECK ENGINE warning light/mal-
function indicator light may turn on. If this
happens, return to your authorized
SUBARU Dealer for service. If it is
determined that the condition is caused
by the type of fuel used, repairs may not
be covered by your warranty.
!Gasoline for cleaner air
CAUTION
Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels con-
taining alcohol may cause paint
damage, which is not covered under
the SUBARU Limited Warranty.
Your use of gasoline with detergent

Continuously variable trans-
mission
The continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
WARNING
Do not shift from the“P”or“N”
position into the“D”or“R”position
while depressing the accelerator
pedal. This may cause the vehicle
to lurch forward or backward.
CAUTION
.Shift into the“P”or“R”position
only after the vehicle is comple-
tely stopped. Shifting while the
vehicle is moving may cause
damage to the transmission.
.Do not race the engine for more
than 5 seconds in any position
except the“N”or“P”position
when the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
.Do not shift from the“D”positioninto the“R”position or vice
versa until the vehicle has com-
pletely stopped. Such shifting
may cause damage to the trans-
mission.
.When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the“P”position. Do not park for
a long time with the select lever
in any other position as doing so
could result in a dead battery.
NOTE
.When the engine coolant tempera-
ture is still low, the transmission will
upshift to higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automatically
shift to the normal timing after the
engine has warmed up.
.Immediately after transmission fluid
is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the currentcondition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
.When driving under continuous hea-
vy load conditions such as towing a
camper or climbing a long, steep hill,
the engine speed or the vehicle speed
may automatically be reduced. This is
not a malfunction. This phenomenon
results from the engine control func-
tion maintaining the cooling perfor-
mance of the vehicle. The engine and
vehicle speed will return to a normal
speed when the engine is able to
maintain the optimum cooling perfor-
mance after the heavy load decreases.
Driving under a heavy load must be
performed with extreme care. Do not
try to pass a vehicle in front when
driving on an uphill slope while towing.
.The continuously variable transmis-
sion is a chain type system that
provides superior transmission effi-
ciency for maximum fuel economy. At
times, depending on varying driving
conditions, a chain operating noise
may be heard that is characteristic of
this type of system.

&Washing
CAUTION
.When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance will
be longer. To dry the brakes,
drive the vehicle at a safe speed
while lightly pressing the brake
pedal to heat up the brakes.
.Do not wash the engine compart-
ment and areas adjacent to it. If
water enters the engine air in-
take, electrical parts or the power
steering fluid reservoir, it will
cause engine trouble or a mal-
function of the power steering.
.Do not use any organic solvents
when washing the surface of the
bulb assembly cover. However, if
a detergent with organic solvents
is used to wash the cover sur-
face, completely rinse off the
detergent with water. Otherwise,
the cover surface may be da-
maged.
.Outback: Since your vehicle is
equipped with a rear wiper, auto-
matic car-wash brushes couldbecome tangled around it, dama-
ging the wiper arm and other
components. Ask the automatic
car-wash operator not to let the
brushes touch the wiper arm or
to fix the wiper arm on the rear
window glass with adhesive tape
before operating the machine.
NOTE
When having your vehicle washed in
an automatic car wash, make sure
beforehand that the car wash is of
suitable type.
The best way to preserve your vehicle’s
beauty is frequent washing. Wash the
vehicle at least once a month to avoid
contamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash
the vehicle with hot water and in direct
sunlight.
Salt, chemicals, insects, tar, soot, tree
sap, and bird droppings should be washed
off by using a light detergent, as required.
If you use a light detergent, make certain
that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly
flushed from the surface and not allowedto dry there. Rinse the vehicle thoroughly
with plenty of lukewarm water. Wipe the
remaining water off with a chamois or soft
cloth.
!Washing the underbody
Chemicals, salts and gravel used for
deicing road surfaces are extremely cor-
rosive, accelerating the corrosion of un-
derbody components, such as the exhaust
system, fuel and brake lines, brake
cables, floor pan and fenders, and sus-
pension.
Thoroughly flush the underbody and in-
side of the fenders with lukewarm or cold
water at frequent intervals to reduce the
harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or
sandy roads, wash the mud and sand off
the underbody.
Carefully flush the suspension and axle
parts, as they are particularly prone to
mud and sand buildup. Do not use a
sharp-edged tool to remove caked mud.
CAUTION
.Be careful not to damage brake
hoses, sensor harnesses, and

Maintenance and service/Cooling system
Cooling system
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap is
removed.
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). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top off the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand ortype, 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.
&Cooling fan, hose and con-
nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to“Temperature gauge”
F3-11.
Check the fuse and replace it if necessary.
Refer to“Fuses”F11-38 and“Fuses and
circuits”F12-10. If the fuse is not blown,
have the cooling system checked by your
SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections bechecked for leaks, damage, or looseness.
&Engine coolant
!Checking the coolant level
1)“FULL”level mark
2)“LOW”level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW”level mark, add coolant up to the
“FULL”level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required.
3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.
