Instruments and controls
Do not operate the engine with the oil pressure
warning light on. This may cause serious en-
gine damage.
AT OIL TEMPerature warning
light (for AT vehicles)
If this light comes on when the engine is running, it
may indicate that the automatic transmission fluid tem-
perature is too hot.
If the light comes on while driving, it is unnecessary to
stop the vehicle, but avoid driving up steep grades or
in stop and go traffic. Automatic transmission control system warn-
ing
If the light flashes after the engine starts, it may indi-
cate that the automatic transmission control system is
not working properly. Contact your nearest SUBARU
dealer for service immediately. 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 work properly.
When the warning light is on, the ABS function
shuts down; however, the conventional brake
system continues to operate normally.
The warning light does not come on when the
ignition switch is turned to the “ON” position. The warning light comes on when the ignition
switch is turned to the “ON” position, but it
does not go out even when the vehicle speed
exceeds approximately 8 mph (12 km/h). The warning light comes on during driving.
If these occur, have the ABS system repaired at
the first available opportunity by your SUBARU
dealer.
With a vehicle equipped with an EBD system, the ABS
warning light comes on together with the brake system
warning light if the EBD system becomes faulty. For

further details of the EBD system fault warning, refer
to “Brake system warning light”.
NOTE
If the warning light behavior is as shown below,
the ABS system may be considered normal.The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off. The warning light remains on after the engine
has been started, but it goes out when the vehicle
speed reaches about 8 mph (12 km/h). The warning light comes on during driving, but
it goes out immediately and remains off.
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. Brake system warning light
Driving with the brake system warning light
on is dangerous. This indicates your brake sys- tem may not be working properly. If the light re-
mains on, have the brakes inspected by a
SUBARU dealer immediately.
If at all in doubt about whether the brakes are
operating properly, do not drive the vehicle.
Have your vehicle towed to the nearest
SUBARU dealer for repair.
This light has the following three functions: Parking brake warning
The light comes on with the parking brake applied
while the ignition switch is in the “ON” position. It goes
out when the parking brake is fully released. Brake fluid level warning
This light comes on when the brake fluid level has
dropped to near the “MIN” level of the brake fluid res-
ervoir with the ignition switch in the “ON” position and
with the parking brake fully released.
If the brake system warning light should come on while
driving (with the parking brake fully released and with
the ignition switch positioned in “ON”), it could be an
indication of leaking of brake fluid or worn brake pads.
If this occurs, immediately stop the vehicle at the near-
est safe place and check the brake fluid level. If the flu-
(U.S.) (Canada)

id level is below the “MIN” mark in the reservoir, do not
drive the vehicle. Have the vehicle towed to the near-
est SUBARU dealer for repair.
Electronic Brake Force Distribution (EBD) sys-
tem warning (for vehicles with EBD)
The brake system warning light also illuminates if a
malfanction occurs in the EBD system. In that event, it
comes on together with the ABS warning light.
The EBD system may be faulty if the brake system
warning light and ABS warning light illuminate simulta-
neously during driving.
Even if the EBD system fails, the conventional braking
system will still function. However, the rear wheels will
be more prone to locking when the brakes are applied
harder than usual and the vehicle’s motion may there-
fore become somewhat harder to control.
If the brake system warning light and ABS warning
light illuminate simultaneously, take the followingsteps:
1. Stop the vehicle in the nearest safe, flat place. If
you cannot avoid parking the vehicle on a slope, use
chocks to prevent the vehicle from moving.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both warning lights go
out, the system is normal and no further action is nec- essary.
4. If both warning lights come on again and stay illu- minated after the engine has been restarted, shut
down the engine again, apply the parking brake, and
check the brake fluid level.
5. If the brake fluid level is not below the “MIN” mark,
the EBD system may be faulty. Drive carefully to the
nearest SUBARU dealer and have the system inspect-
ed.
6. If the brake fluid level is below the “MIN” mark, DO
NOT drive the vehicle. Instead, have the vehicle towed
to the nearest SUBARU dealer for repair.
Door open warning lights
The door open warning light comes on if any door or
the rear gate is not fully closed.
Always make sure this light is out before you start to drive. Low fuel warning light
The low fuel warning light comes on when the tank is
nearly empty about 2.3 U.S. gal. (9.0 liters, or 1.9 Imp.
gal.). It only operates when the ignition switch is in the
“ON” position.
NOTE
This light does not go out unless the tank is re-
plenished up to an internal fuel quantity of about

more than just a few seconds.
Daytime running light system
The tail lights, parking lights, and side marker
lights are not turned on by the daytime running
light system. The light switch must always be
turned to the “ ” position when it is dark
outside.
The low beam headlights will automatically come on at
reduced brightness when the engine has started, un-
der the following conditions: The parking brake is fully released.
The light switch is in the “OFF” or “ ” position.
The automatic transmission selector lever is set at
other than the “P” position.

Defrosting or defogging
To direct warm air to the windshield and front door win-
dows:
1. Set the air flow control dial to the “ ” position.
2. Set the temperature control dial to the red side.
3. Set the fan speed control dial at the highest speed.
The air conditioner compressor automatically oper-
ates when the air flow control dial set in the “ ” or
“ ” position to provide better defogging perfor-
mance.
However, the air conditioner indicator light does not
come on at this time. Automatic climate control system (if
equipped)
NOTE
Operate the automatic climate control system
when the engine is running. When the engine coolant is cold, the blower
does not run. In the “AUTO” mode, when the air temperature
in the passenger compartment is sufficiently cool,
the air conditioner compressor does not operate.
For efficient defogging or dehumidifying in cold
weather, press the “A/C” switch on. Even when cooling is not necessary, setting the
temperature much lower than the current outlet air
temperature turns on the air conditioner compres-
sor automatically and the “A/C” indicator light on
the control panel comes on.
The automatic climate control system automatically
controls outlet air temperature, fan speed, air flow dis-
tribution air-inlet control, and air conditioner compres-
sor operation. It activates when the “AUTO” switch is
pressed, and is used in conjunction with the Temper-
ature control dial to maintain a constant, comfortable
climate within the passenger compartment.
The temperature can be set within a range of 65 –

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.
