Temperature sensors
1) Solar sensor
2) Interior air temperature sensor
The automatic climate control system
employs several sensors. These sensors
are delicate. If they are treated incorrectly
and become damaged, the system may
not be able to control the interior tempera-
ture correctly. To avoid damaging the
sensors, observe the following precau-tions: – Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows:– Solar sensor: beside windshield
defroster grille Climate control

4-12Climate control
–Interior air temperature sensor: on the
side of the driver-side part of the center panel – Outside temperature sensor: behind
front grille. Operating tips for heater and
air conditioner &
Cleaning ventilator grille
Always 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 sunlight
After 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 circuit
Operate 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-son
Check 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 condition
Under 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 conditioningsystem.

&Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steepupgrade. & Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od of adding, changing or checking the
refrigerant is different from the method for
CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are
not covered under warranty. Air filtration system (if equipped)
If your vehicle
’s air conditioning system is
equipped with an air filtration system,
replace the filter element according to
the replacement schedule shown in the
following. This schedule should be fol-
lowed to maintain the filter ’s dust collec-
tion ability. Under extremely dusty condi-
tions, the filter should be replaced more
frequently. Have your filter checked or
replaced by your SUBARU dealer. For
replacement, we recommend the use of a
genuine SUBARU air filter kit.
Replacement schedule: Every 12 months or 9,300 miles (15,000
km) whichever comes first
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter: – Reduction of the air flow through
the vents.
– Windshield gets easily fogged ormisted. NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.

Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause engine damage.
& Fuel requirements
! 2.5-liter 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. ! 2.5-liter 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 unleadedgasoline. NOTE
Be sure to use premium unleaded
gasoline of 91 AKI or higher for a 2.5-
liter turbo engine model. If other gaso-
line (lower than 91 AKI) is used, knock-
ing, reduced output and poor accelera-
tor response will result. !
3.0-liter models
The 3.0-liter engine is designed to operate
using unleaded gasoline with an octane
rating of 91 AKI or higher. Regular
unleaded gasoline with an octane rating
of 87 AKI or higher may be used. However
for optimum engine performance and
driveability, it is recommended that you
use 91 AKI or higher grade unleaded
gasoline. You may experience reduced
output, poor accelerator response, and
reduced fuel economy when using gaso-
line with an octane rating lower than 91
AKI, depending on your driving habits and
conditions. If you experience any of these
conditions while using a lower octane
rated fuel, you may want to return to using
91 AKI octane rated fuel as soon as
possible. Additionally, if your vehicle
knocks heavily or persistently, or if you
are driving with heavy loads such as when
towing a trailer, the use of 91 AKI or higher
grade unleaded gasoline is required. !
Fuel octane rating
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).
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. ! 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 Starting and operating
7-3
– CONTINUED –

7-4Starting and operating
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 thefollowing. .
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.

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 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 emissiontest.
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 isrunning. . 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 vehicle
fails the OBD inspection if the
“ CHECK ENGINE ”warning light/MIL is
