to defrost or to dehumidify the windshield
and front door windows.
.Select the“
”mode by pressing the
defroster button (both types A and B)
.Select the“”mode by turning the
airflow mode selection dial (type A)
.Select the“”mode by pressing the
airflow mode selection button (type B)
NOTEWhen the“
”or“
”mode is se-
lected, the air conditioner compressor
operates automatically regardless of
the position of the air conditioner
button to defrost the windshield more
quickly. However the indicator on the
air conditioner button will not illumi-
nate. At the same time, the air inlet
selection is automatically set to the
outside air mode. After defrosting the
windshield by pressing the defroster
button“
”, pressing the button again
returns the system to the setting that
had been selected before the defroster
was activated.
Operating tips for heater and
air conditioner&Cleaning ventilation grille1) Front ventilation inlet 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 effi-
ciency.&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.

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.
!MMT
Some gasoline contains an octane-enhan-
cing additive called MMT (Methylcyclo-
pentadienyl 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
Your use of gasoline with detergent ad-
ditives will help prevent deposits from
forming in your engine and fuel system.
This helps keep your engine in tune and
your emission control system working
properly, and is a way of doing your part
for cleaner air. If you continuously use a
high quality fuel with the proper detergent
and other additives, you should never
need to add any fuel system cleaningagents to your fuel tank.
Many gasolines are now blended with
materials called oxygenates. Use of these
fuels can also help keep the air cleaner.
Oxygenated blend fuels, such as ethanol
(ethyl or grain alcohol) may be used in your
vehicle, but should contain no more than
10% ethanol for the proper operation of
your SUBARU.
Do not use any gasoline that contains
more than 10% ethanol, including from any
pump labeled E15, E30, E50 or E85 (which
are only some examples of fuel containing
more than 10% ethanol).
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,
you should ask your service station op-
erators if their gasolines contain deter-
gents and oxygenates and if they have
been reformulated to reduce vehicle emis-
sions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
.Fuel should be unleaded and have anoctane rating no lower than that specified
in this manual.
.Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLYif it does not exceed 5% of the fuel
mixtureANDif it is accompanied by
sufficient quantities of the proper cosol-
vents and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanolEXCEPT
under these conditions.
.If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
.Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.
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.

.When opening the cap, grasp it
firmly and turn it slowly to the left.
Do not remove the cap quickly.
Fuel may be under pressure and
spray out of the fuel filler neck,
especially in hot weather. If you
hear a hissing sound while you
are removing the cap, wait for the
sound to stop and then slowly
open the cap to prevent fuel from
spraying out and creating a fire
hazard.3. Set the fuel filler cap on the cap holder
inside the fuel filler lid.
WARNING
.When refueling, insert the fuel
nozzle securely into the fuel filler
pipe. If the nozzle is lifted or not
fully inserted, its automatic stop-
ping mechanism may not func-
tion, causing fuel to overflow the
tank and creating a fire hazard.
.Stop refueling when the auto-
matic stop mechanism on the
fuel nozzle activates. If you con-
tinue to add fuel, temperature
changes or other conditions
may cause fuel to overflow from
the tank and create a fire hazard.
4. Stop filling the tank after the fuel filler
pump automatically stops. Do not add any
more fuel.
5. Put the cap back on, turn it clockwise
until you hear a clicking noise. Be certain
not to catch the tether under the cap while
tightening.
CAUTION
Make sure that the cap is tightened
until it clicks to prevent fuel spillage
in the event of an accident.
6. Close the fuel filler lid completely.
CAUTION
If you spill any fuel on the painted
surface, rinse it off immediately.
Otherwise, the painted surface
could be damaged.NOTE.You will see the“
”sign in the fuel
gauge. This indicates that the fuel filler
door (lid) is located on the right side of
the vehicle.
.If the fuel filler cap is not tightened
until it clicks or if the tether is caught
under the cap, the CHECK ENGINE
warning light/malfunction indicator
light may illuminate. Refer to“CHECK
ENGINE warning light/Malfunction in-
dicator light”F3-16.
CAUTION
.Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system.
.After refueling, turn the cap
clockwise until it clicks to ensure
that it is fully tightened. If the cap
is not securely tightened, fuel
may leak out while the vehicle is

being driven or fuel spillage
could occur in the event of an
accident, creating a fire hazard.
.Do not let fuel spill on the exterior
surfaces of the vehicle. Because
fuel may damage the paint, be
sure to wipe off any spilled fuel
quickly. Paint damage caused by
spilled fuel is not covered under
the SUBARU Limited Warranty.
.Always use a genuine SUBARU
fuel filler cap. If you use the
wrong cap, it may not fit or have
proper venting and your fuel tank
and emission control system
may be damaged. It could also
lead to fuel spillage and a fire.
.Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank could
cause damage to the engine.
Continuing to operate your vehi-
cle at an extremely low fuel level
may result in a reduction of
engine performance.
State emission testing
(U.S. only)
WARNING
Only use a four-wheel dynamometer
when testing an All-Wheel Drive
(AWD) model.
TestingofanAWDmodelmust
NEVER be performed on a single
two-wheel dynamometer. Attempt-
ing to do so will result in uncon-
trolled vehicle movement and may
cause an accident or injuries to
persons nearby.
CAUTION
.At state inspection time, remem-
ber to tell your inspection or
service station in advance not to
place your SUBARU AWD vehicle
on a two-wheel dynamometer.
Otherwise, serious transmission
damage will result.
.Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of
the state inspection program orits contractors or licensees.
California and a number of federal states
have Inspection/Maintenance programs to
inspect your vehicle’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed
to detect engine and transmission pro-
blems that might cause the vehicle emis-
sions to exceed allowable limits. OBDII
inspections apply to all 1996 model year
and newer passenger cars and trucks.
Over 30 states plus the District of Colum-
bia have implemented emission inspection
of the OBDII system.
.The inspection of the OBDII system
consists of a visual operational check of
the“CHECK ENGINE”warning light/mal-
function indicator light (MIL) and an ex-
amination of the OBDII system with an
electronic scan tool.
.A vehicle passes the OBDII system
inspection if proper operation of the
“CHECK ENGINE”warning light is ob-

served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.
.A vehicle fails the OBDII inspection if
the“CHECK ENGINE”warning light is not
properly operating (light is illuminated or is
not working due to faulty LED [Light
Emitting Diode]) or there is one or more
diagnostic trouble codes stored in the
vehicle’s computer.
.A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors“NOT
READY”is greater than one. If the
vehicle’s battery has been recently re-
placed or disconnected, the OBDII system
inspection may indicate that the vehicle is
not ready for the emission test. Under this
condition, the vehicle driver should be
instructed to drive his/her vehicle for a
few days to reset the readiness monitors
and return for an emission re-inspection.
.Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Some states still use dynamometers in
their emission inspection program. A
dynamometer is a treadmill or roller-like
testing device that allows your vehicle’s
wheels to turn while the vehicle remains in
one place. Prior to your vehicle being puton a dynamometer, tell your emission
inspector not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer.Otherwise, serious transmis-
sion damage will result.
The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
program have EXEMPTED SUBARU
AWD vehicles from the portion of the
testing program that involves a two-wheel
dynamometer. There are some states that
use four-wheel dynamometers in their
testing program. When properly used, this
equipment should not damage a SUBARU
AWD vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected in
an attempt to bypass AWD for state
emission testing. An AWD vehicles must
be tested using an AWD dynamometer
with all 4 wheels driven and loaded.
Preparing to driveYou should perform the following checks
and adjustments every day before you
start driving.
1. Check that all windows, mirrors, and
lights are clean and unobstructed.
2. Check the appearance and condition
of the tires. Also check tires for proper
inflation.
3. Look under the vehicle for any sign of
leaks, and check that no small animal is
under the vehicle.
4. Check that no small animal enters the
engine compartment.
5. Check that the hood and trunk lid are
fully closed.
6. Check the adjustment of the seat.
7. Check the adjustment of the inside and
outside mirrors.
8. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
9. Check the operation of the warning
and indicator lights when the ignition
switch is turned to the“ON”position.
10. Check the gauges, indicator and warn-
ing lights after starting the engine.

CAUTION
Trapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.NOTEEngine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
Starting and stopping the en-
gine&General precautions when
starting/stopping engine
WARNING
.Never start the engine from out-
side the vehicle. It may result in
an accident.
.Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can cre-
ate a fire hazard at high tempera-
tures.
.Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
CAUTION
.Do not stop the engine while
driving. Otherwise, the catalyst
may overheat and burn.
.When starting the engine, be sureto sit in the driver’s seat (except
when using the remote engine
start system).
NOTE.Avoid rapid acceleration immedi-
ately after the engine has started. In
addition, always avoid rapid racing.
.Until the engine is warmed up suffi-
ciently, the engine speed is maintained
high. The engine speed will gradually
drop as the engine warms up.
.On rare occasions, it may be difficult
to start the engine depending on the
fuel used and the driving condition
(repeated short trips when the engine
is not warmed up sufficiently). In such
cases, it is recommended to switch to a
different brand of fuel.
.On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly such
as a rapid start-up and a rapid accel-
eration. This is not a malfunction.
.The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.
.It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically
