Wiper and washer
NOTE
y The wiper operates only when the ig-
nition switch is in the “ON” or “ACC”
position. y Clean your wiper blades and window
glass periodically with a washer solu-
tion to prevent streaking, and to re-
move accumulations of road salt or
road film. Keep the washer button de-
pressed at least for 1 second so that
washer solution will be sprinkled all
over the windshield or rear window. y Grease, wax, insects or other materi-
al on the windshield or the wiper blade
results in jerky wiper operation and
In freezing weather, do not use the
windshield washer until the wind-
shield is sufficiently warmed by the
defroster.
Otherwise the washer fluid can
freeze on the windshield, blocking
your view. y Do not operate the washer contin-
uously for more than ten seconds,
or when the washer fluid tank is
empty. This may cause overheat-
ing of the washer motor. Check
the washer fluid level frequently,
such as at fuel stops.
y Do not operate the wipers when
the windshield or rear window is
dry. This may scratch the glass,
damage the wiper blades and
cause the wiper motor to burn out.
Before operating the wiper on a
dry windshield or rear window, al-
ways use the windshield washer.
y In freezing weather, be sure that
the wiper blades are not frozen to
the windshield or rear window be-
fore switching on the wipers. At-
tempting to operate the wiper with
the blades frozen to the window
glass could cause not only the
wiper blades to be damaged but
also the wiper motor to burn out. If
the wiper blades are frozen to the
window glass, be sure to operate
the defroster, windshield wiper
deicer (if equipped) or rear win-
dow defogger before turning on
the wiper.
y If the wipers stop during opera-
tion because of ice or some other
obstruction on the window, the
wiper motor could burn out even if
the wiper switch is turned off. If
this occurs, promptly stop the ve-
hicle in a safe place, turn the igni-
tion switch to the “LOCK” posi-
tion and clean the window glass
to allow proper wiper operation.yUse clean water if windshield
washer fluid is unavailable. In ar-
eas where water freezes in winter,
use SUBARU Windshield Washer
Fluid or the equivalent. (See the
“Windshield washer fluid” section
in chapter 11.)
Also, when driving the vehicle
when there are freezing tempera-
tures, use non-freezing type wiper
blades.
y Do not clean the wiper blades with
gasoline or a solvent, such as
paint thinner or benzene. This will
cause deterioration of the wiper
blades.

Sta rting an d o peratingFuel
„Fuel requirements
T Non-turbo models
The 2.5-liter non-turbo engine is designed
to operate using unleaded gasoline with
an octane rating of 87 AKI or higher. T Turbo models
The 2.5-liter turbo engine is designed to
operate using premium unleaded gasoline
with an octane rating of 91 AKI or higher.
If premium unleaded gasoline is not avail-
able, regular unleaded gasoline with an
octane rating of 87 AKI or higher may be
temporarily used. For optimum engine
performance and driveability, it is required
that you use premium grade unleaded
gasoline.
NOTE
Be sure to use premium unleaded gas-
oline of 91 AKI or higher for a 2.5-liter
turbo engine model. If other gasoline
(lower than 91 AKI) is used, knocking, reduced output and poor accelerator
response will result. T
Fuel octane rating
This octane rating is the average of the
Research Octane and Motor Octane num-
bers and is commonly referred to as the
Anti Knock Index (AKI).
Using a gasoline with a lower octane rat-
ing can cause persistent and heavy
knocking, which can damage the engine.
Do not be concerned if your vehicle some-
times 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. T 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. T Gasoline for California-certified LEV
Your vehicle was certified to California’s
low emission vehicle (LEV) standards as
indicated on the underhood tune-up label,
it is designed to optimize engine and
emission performance with gasoline that meets the clean burning low-sulfur Califor-
nia gasoline specifications. If you live in
any other state than California, your vehi-
cle will operate on gasoline meeting Fed-
eral specifications. Gasoline sold outside
California is permitted to have higher sul-
fur levels, which may affect the perfor-
mance of your vehicle’s catalytic convert-
er 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 returning
your vehicle to an authorized dealer for
service. T
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 lamp may turn on. If this
happens, return to your authorized
SUBARU Dealer for service. If it is deter-
mined that the condition is caused by the
type of fuel used, repairs may not be cov-
ered by your warranty.
Use of a fuel which is low in quality
or use of an inappropriate fuel addi-
tive may cause engine damage.

buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,
being careful not to damage the disc
brakes and brake hoses and ABS har-
ness. T
Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weath- er.
Use only additives that are specifically de-
signed for this purpose. When an anti-
freeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used for
an extended period, it is best to have the
fuel tank filled to capacity. „ Driving on snowy and icy roads
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the en-
gine brake effectively to control the vehi-
cle speed. (Shift into a lower gear when
necessary.)
Avoid shifting down abruptly. Such behav-
ior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) enhanc-
es your vehicle’s braking performance on
snowy and icy roads. Refer to the “ABS
(Anti-lock Brake System)” section in chap-
ter 7 for information on braking on slippery
surfaces. TWiper operation when snowing
Before driving in cold weather, make sure the wiper blades are not frozen to the
windshield or rear window. If the wiper
blades are frozen to the windshield or rear
window, use the defroster with the airflow
control button/dial in the “ ” position
and the temperature control dial set for
maximum warmth until the wiper blades
are completely thawed out. If your vehicle
is equipped with a wiper deicer, it is helpful
to thaw the windshield wiper blades. To
thaw out the rear wiper blade, use the rear
window defogger.
When driving in snow, if frozen snow
starts to stick on the surface of the wind-
shield despite wiper operation, use the de-
froster with the airflow control button/dial
in “ ” and the temperature control dial
set for maximum warmth. After the wind-
shield gets warmed enough to melt the
frozen snow on it, wash it away using the
windshield washer.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and sub-
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of vehi-
cle control.
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine’s intake system and may
hinder the air flow, which could re-
sult in engine shutdown or even
breakdown.

10-2 Appearance care
Appe arance ca reExterior care „WashingNOTE
When having your vehicle washed in
an automatic car wash, make sure be-
forehand that the car wash is of suit-
able type.
The best way to preserve your vehicle’s
beauty is frequent washing. Wash the ve-
hicle at least once a month to avoid con-
tamination 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 allowed
to dry there. Rinse the vehicle thoroughly
with plenty of lukewarm water. Wipe the
remaining water off with a chamois or soft
cloth. TWashing the underbody
Chemicals, salts and gravel used for deic-
ing road surfaces are extremely corrosive,
accelerating the corrosion of underbody components, such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders, and suspension.
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 muddy or sandy
roads, wash the mud and sand off the un-
derbody.
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.
NOTE
Be careful not to damage brake hoses,
sensor harnesses, and other parts
when washing suspension compo-
nents. T
Using a warm water washer
y Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle. y Do not wash the same area continuous-
ly. y If a stain will not come out easily, wash
by hand. Some warm water washers are
y
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.
y Do not wash the engine compart-
ment and area adjacent to it. If wa-
ter enters the engine air intake,
electrical parts or the power steer-
ing fluid reservoir, it will cause en-
gine trouble or faulty power steer-
ing respectively.
y Since your vehicle is equipped
with a rear wiper, automatic car-
wash brushes could become tan-
gled around it, damaging the wip-
er arm and other components.
Ask the automatic car-wash oper-
ator 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.

SAE viscosity number and applicable
temperature
*: 5W-30 is recommended.
Engine 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 engine.
„ Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in ar- eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM (or SL):
SAE viscosity No.:
30, 40, 10W-50, 20W-40, 20W-50
„ Synthetic oil
You can use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual, and must follow
the oil and filter changing intervals shown
in the maintenance schedule.
Cooling system
Use only engine oil with the recom-
mended grade and viscosity.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.
The cooling system has been filled
at the factory with a high quality,
corrosion-inhibiting, year-around
coolant which provides protection
against freezing down to –33 qF
(–36 qC). For adding, use genuine
SUBARU coolant or an equivalent: a
mixture of 50% soft water (or clear
and drinkable water) and 50% phos-
phate or non-amine type coolant.
Use of improper coolants may result
in corrosion in the cooling system. It
is important to maintain protection
against freezing and corrosion,
even if freezing temperatures are
not expected. Never mix different
kinds of coolant.
