sidered normal. "The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off. " The warning light comes on after engine startup
and goes off while the vehicle is subsequently be-
ing driven. " The warning light comes on during driving, but
it goes out immediately and remains off. ! Vehicle Dynamics Control OFF indicator light
" It comes on when the Vehicle Dynamics Control
OFF switch is pressed. " It also comes on when the Vehicle Dynamics Con-
trol system is deactivated.
NOTE " The light may stay on for a while after the engine
has been started, especially in cold weather. This
does not indicate the existence of a problem. The
light should go out as soon as the engine has
warmed up. " The indicator light comes on when the engine
has developed a problem and the Malfunction in-
dicator light is on.
The Vehicle Dynamics Control system is probably
faulty under the following condition. Have your vehicle checked at a SUBARU dealer as soon as possible."
The light does not go out even after the lapse of sev-
eral minutes (the engine has warmed up) after the en-
gine has started. ! Security indicator light
This indicator light shows the status of the alarm sys-
tem. If your vehicle is equipped with an immobilizer, it
also indicates operation of the immobilizer system. ! Alarm system
It blinks to show the driver the operational status of the
alarm system. For detailed information, refer to the
“Alarm system” in Chapter 2. ! Immobilizer system (if equipped)
This light blinks about 60 seconds after the ignition
switch is turned from “ON” position to the “ACC” or
“LOCK” position or immediately after the key is pulled
out. (Refer to the “Door locks” section in chapter 2.)
If the indicator light does not flash, it may indicate that
immobilizer system may be faulty. Contact your near-
est SUBARU dealer immediately.
In the event that an unauthorized key (for example, an
unauthorized duplicate) is used, the security indicator
light comes on.

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.
Have your SUBARU dealer perform this check. !
Cooling and dehumidifying in high hu-
midity and low temperature weather condition
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 accelera-
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.

Standards as indicated on the underhood tune-up la-
bel. It is designed to optimize engine and emission
control system performance with gasoline that meets
the clean burning low-sulfur California gasoline speci-
fications. If you live in any other state than California,
your vehicle will operate on gasoline meeting Federal
specifications. Gasoline sold outside California is per-
mitted to have higher sulfur levels, which may affect
the performance of your vehicle’s catalytic converter
and may produce a sulfur exhaust odor or smell. SUB-
ARU recommends that you try a different brand of un-
leaded gasoline having lower sulfur to determine if the
problem is fuel related before returning your vehicle to
an authorized dealer for service. The CHECK EN-
GINE 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, re-
pairs may not be covered by your warranty. !MMT
Some gasoline contains an octane-enhancing additive
called MMT (Methylcyclopentadienyl Manganese Tri-
carbonyl). If you use such fuels, your emission control
system performance may deteriorate and the CHECK
ENGINE warning light/Malfunction 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
Do not let fuel spill on the exterior surfaces of
the vehicle. Fuels containing alcohol may
cause paint damage, which is not covered un-
der 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 continu-
ously 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 con-
tain no more than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.

"You will see the “ ” sign in the combination
meter. 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 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. If
the engine misfired as a result of an empty tank,
resulting catalyzer damage could cause damage
to the turbocharger.
" 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. " Do not let fuel spill on the exterior surfaces of
the vehicle. Fuels may cause paint damage,
which is not covered under the SUBARU Limit-
ed 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 emis-
sion control system might be damaged.

jacked off the ground, nor should the driveshaft be dis-
connected for state emission testing.
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. About 30
states plus the District of Columbia have implemented
the OBD system inspection. "The inspection of the OBD system consists of a vi-
sual operational check of the “ CHECK ENGINE” warn-
ing light/malfunction indicator lamp (MIL) and an ex-
amination 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 illumi-
nation is observed, there is no stored diagnostic trou-
ble codes, and the OBD system readiness monitors
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 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.

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, trunk and rear gate are fullyclosed.
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.

switch again to the “OFF” position. After waiting for
10 seconds or longer, turn the ignition switch to the
“START” position without depressing the accelera-
tor pedal.
4) If the engine still refuses to start, contact your
nearest SUBARU dealer for assistance.
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
If you restart the engine while the vehicle is
moving, shift the selector lever into the “N” po-
sition. Do not attempt to place the selector lever
of a moving vehicle into the “P” position.
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.

The ABS system prevents the lock-up of wheels which
may occur during sudden braking or braking on slip-
pery road surfaces. This helps prevent the loss of
steering control and directional stability caused by
wheel lock-up.
When the ABS system is operating, you may hear a
chattering noise or feel a slight vibration in the brake
pedal. This is normal when the ABS operates.
The ABS system will not operate when the vehicle
speed is below approximately 6 mph (10 km/h). !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.
If the warning light behaves as follows, the ABS
system may not be working properly.
When the warning light is on, the ABS function
shuts down; however, the conventional brake
system continues to operate normally.
