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 cool-
ing efficiency. Lubrication oil circulation in the refrig-
erant circuit
Operate the air conditioner compressor at a low en-
gine speed (at idle or low driving speeds) a few min-
utes each month during the off-season to circulate its
oil. Checking air conditioning system be-
fore summer season
Check the air conditioner unit for refrigerant leaks,
hose conditions, and proper operation each spring.
This check is best performed by your SUBARU dealer.
Cooling and dehumidifying in high hu-
midity and low temperature weather
conditions
Under certain weather conditions (high relative humid-
ity, 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. Air conditioner compressor shut-off
when engine is heavily loaded
To improve acceleration and gas mileage, the air con-
ditioner compressor is designed to temporarily shut off
during air conditioner operation whenever the acceler-
ator is fully depressed such as during rapid accerela-
tion or when driving on a steep upgrade. Refrigerant for your climate control
system
Your air conditioner uses ozone friendly refrigerant
HFC134a. Therefore, the method 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.

1) Open
2) Close
2. Remove the fuel filler cap by turning it slowly coun-
terclockwise.
Gasoline vapor is highly flammable. Before
refueling, always first stop the engine and make
sure that there are no lighted cigarettes, open
flames or electrical sparks in the adjacent area. When opening the cap, do not remove the
cap quickly. Fuel may be under pressure and
spray out of the fuel filler neck especially in hot
weather, which may cause injury.
3. Stop filling the tank after the fuel filler pump auto-
matically stops. Do not add any more fuel.
4. Put the cap back on, turn it clockwise until you hear
a clicking noise. Be certain not to catch the tether un-
der the cap while tightening.
5. Close the fuel filler lid completely.
If you spill any fuel on the painted surface, rinse it off
immediately. Otherwise, the painted surface could be
damaged.
NOTE
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 may come on. Refer to the
“Warning and indicator lights” section located in
chapter 3.
Never add any cleaning agents to the fuel
tank. The addition of a cleaning agent may
cause damage to the fuel system. Make sure that the cap is tightened until it
clicks to prevent fuel spillage in the event of an
accident.

states using two-wheel dynamometers in their emis-
sion testing programs have EXEMPTEDSubaru AWD
vehicles from the portion of the testing program that in-
volves a two-wheel dynamometer.
There are some states that use four-wheel dynamom-
eters in their testing programs. When properly used,
that equipment will not damage an AWD Subaru vehi- cle.
Under no circumstances should the rear wheels be
jacked off the ground, nor should the driveshaft be dis-
connected for state emission testing.
Testing of an All-Wheel Drive vehicle must
NEVERbeperformedonasingletwo-wheeldy-
namometer. Attempting to do so will result in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby.
Resultant vehicle damage due to improper test-
ing is not covered under the SUBARU Limited
Warranty and is the responsibility of the state inspection program or its contractors or licens-
ees.
The EPA has issued regulations for inspecting the On-
Board Diagnostic (OBD) system as part of the state
emissions inspection. The OBD system is designed to
detect engine and transmission 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. Several states
plus the District of Columbia have opted to start the
OBD system inspection prior to the required EPA reg-
ulation effective date of January 1, 2002. Other states
will add OBD system inspection in 2002. The inspection of the OBD system consists of a vi-
sual operational check of the “CHECK ENGINE”
warning light/malfunction indicator lamp (MIL) and an
examination of the OBD system with an electronic
scan tool while the engine is running A vehicle passes
the OBD system inspection if
proper the “CHECK ENGINE” warning light/MIL illu-
mination is observed, there is nostored diagnostic
trouble codes, and the OBD system readiness moni-
tors are complete. A vehicle fails
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 readiness
monitors “Not Ready” is greater than three. Under
this condition, the vehicle operator should be instruct-
ed 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.Preparing to drive
You should perform the following checks and adjust-
ments 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.
4. Check that the hood and rear gate are fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside and outside mir-
rors.
7. Fasten your seatbelt. Check that your passengers
have fastened their seatbelts.
8. Check the operation of the warning and indicator
lights when the ignition switch is turned to the “ON” po-sition.
9. Check the gauges, indicator and warning lights af-
ter starting the engine.
NOTE
Engine oil, engine coolant, brake fluid, washer flu-
id and other fluid levels should be checked daily,
weekly or at fuel stops.

–CONTINUED –
Starting the engine
Do not operate the starter motor continuously
for more than ten seconds. If the engine fails to
start after operating the starter for five to ten
seconds, wait for ten seconds or more before
trying again.
Manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Press the clutch pedal to the floor and shift the shift
lever into neutral. Hold the clutch pedal to the floor
while starting the engine.
The starter motor will only operate when the clutch
pedal is pressed fully to the floor.
4. Turn the ignition switch to the “ON” position and
check the operation of the warning and indicator lights.
Refer to the “Warning and indicator lights” section
(chapter 3).
5. Turn the ignition switch to the “START” position
without depressing the accelerator pedal. Release
the key immediately after the engine has started. If the engine does not start within ten seconds, wait a
while and then turn the ignition switch to the “START”
position again while depressing the accelerator pedal
half way down.
6. Confirm that all warning and indicator lights have
gone off after the engine has started. The fuel injection
system automatically lowers the idle speed as the en-
gine warms up.
Automatic transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Shift the selector lever to the “P” or “N” position
(preferably “P” position).
The starter motor will only operate when the select le-
ver is at the “P” or “N” position.
4. Turn the ignition switch to the “ON” position and
check the operation of the warning and indicator lights.
Refer to the “Warning and indicator lights” section
(chapter 3).
5. Turn the ignition switch to the “START” position
without depressing the accelerator pedal. Release
the key immediately after the engine has started.
If the engine does not start within ten seconds, wait a
while and then turn the ignition switch to the “START”
position again while depressing the accelerator pedal

cles. When driving on badly surfaced roads, gravel
roads, icy roads, or over deep newly fallen
snow, stopping distances may be longer for a
vehicle with the ABS system than one without.
When driving under these conditions, there-
fore, reduce your speed and leave ample dis-
tance from other vehicles. When you feel the ABS system operating,
you should maintain constant brake pedal pres-
sure. Do not pump the brake pedal since doing
so may defeat the operation of the ABS system.
ABS system self-check
You may feel a slight shock in the brake pedal and
hear the operating sound of ABS from the engine com-
partment just after the vehicle is started. This is
caused by an automatic functional test of the ABS sys-
tem being carried out and does not indicate any abnor-
mal condition.
ABS warning light
The ABS warning light comes on when the ignition
switch is turned to the “ON” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.
When driving with an insufficient battery voltage such
as when the engine is jump started, the ABS warning
light may come on. This is due to the low battery volt-
age and does not indicate a malfunction. When the
battery becomes fully charged, the light will go out.
