panel
– Outside temperature sensor: behind
front grille.
Operating tips for heater and
air conditioner& Cleaning ventilator grilleAlways keep the front ventilator 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
efficiency.
&
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 your
SUBARU dealer perform this check.&Cooling and dehumidifying in
high humidity and low tem-
perature weather conditionUnder certain weather conditions (high
relative humidity, low temperatures, etc.) a
small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate
any problem with the air conditioning
system.

Starting and operating
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 returning
your vehicle to an authorized dealer for
service. The CHECK ENGINE warning
light/malfunction indicator lamp 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 lamp 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
additives 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 cleaning
agents 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 MTBE
(Methyl Tertiary Butyl ether) or ethanol
(ethyl or grain alcohol) may be used in
your vehicle, but should contain no more
than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
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
operators 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.
.
Fuel should be unleaded and have an
octane 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
ONLY if it does not exceed 5% of the fuel
mixture ANDif 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 methanol EXCEPT
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.

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
lamp may come on. Refer to the
“ Warning and indicator lights ”section
located in chapter 3.
(Turbo model only) Promptly put fuel in
the tank whenever the low fuel warning
light comes on. Engine misfires as a
result of an empty tank could cause
damage to the engine.
CAUTION
. Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system.
. Make sure that the cap is tigh-
tened until it clicks to prevent
fuel spillage in the event of an
accident.
. Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels
may cause paint damage, which
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 sys-
tem might be damaged.
State emission testing (U.S.
only)
WARNING
Testing of an All-Wheel Drive vehicle
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby.
CAUTION
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 or its
contractors or licensees.
At state inspection time, remember to
tell your inspection or service station in
advance not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer. Otherwise, serious transmis-
sion damage will result.
Some states have started using dynam-
ometers in their state inspection programs

Starting and operating
in order to meet their obligation under
federal law to implement stricter vehicle
emission standards to reduce air pollution
from vehicles. A dynamometer is a tread-
mill or roller-like testing device that allows
your vehicle’ s wheels to turn while the
vehicle remains in one place. Depending
on the severity of a state ’s air pollution
problems, the states must adopt either a
“basic ”or “enhanced ”vehicle emission
inspection test. Normally, a portion of the
basic emission test consists of an emis-
sion inspector inserting an analyzer probe
into the exhaust pipe of an idling vehicle
for a short period of time. States with more
severe air pollution problems are required
to adopt an enhanced vehicle emission
test. This test simulates actual driving
conditions on a dynamometer and permits
more accurate measurement of tailpipe
emitted pollution than the basic emission
test.
The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
programs have EXEMPTEDSUBARU
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 programs.
When properly used, that equipment will not damage an AWD SUBARU vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
The EPA has issued regulations for
inspecting the On-Board Diagnostic
(OBD) system as part of the state emis-
sions inspection. The OBD system is
designed to detect engine and transmis-
sion problems that might cause vehicle
emissions to exceed allowable limits.
These inspections apply to all 1996 model
year and newer passenger cars and light
trucks. Over 30 states plus the District of
Columbia have implemented the OBD
system inspection.
.
The inspection of the OBD system
consists of a visual operational check of
the “CHECK ENGINE ”warning light/mal-
function indicator lamp (MIL) and an
examination of the OBD system with an
electronic scan tool while the engine is
running.
. Avehicle
passes the OBD system
inspection if proper the “CHECK ENGINE”
warning light/MIL illumination is observed,
there is nostored diagnostic trouble
codes, and the OBD system readiness
monitors are complete.
. A vehiclefails the OBD inspection if the
“CHECK ENGINE ”warning light/MIL is not properly operating or there is one or
more diagnostic trouble codes stored in
vehicle
’s computer with the “CHECK
ENGINE ”warning light/MIL illuminated.
. A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBD system readi ness monitors“Not
Ready” is greater than one. Under this
condition, the vehicle operator should be
instructed to drive his/her vehicle for a few
days to set the monitors and return for an
emission re-inspection.
. Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
