Warning and indicator lights
Several of the warning and indicator lights come on
momentarily and then go out when the ignition switch
is initially turned to the “ON” position. This permits
checking the operation of the bulbs.
Apply the parking brake and turn the ignition switch to
the “ON” position. The following lights come on:
Seatbelt warning light
SRS airbag system warning light
CHECK ENGINE warning light / Malfunction indica- tor lamp
Charge warning light
Oil pressure warning light
AT OIL temperature warning light (AT vehicles) ABS warning light
VDC warning light (if equipped)
VDC operation indicator light (if equipped)
VDC OFF indicator light (if equipped)
Brake system warning light
If any lights fail to come on, it indicates a burned-out
bulb or a malfunction of the corresponding system.
Consult your authorized SUBARU dealer for repair. „
Seatbelt warning light and chime
When the ignition switch is turned to the “ON” position,
the seatbelt warning light will come on and the remind-
er chime will sound for about six seconds to remind the
driver to fasten the seatbelt.
The seatbelt warning light remains on for about six
seconds and turns off automatically after six seconds.
The seatbelt reminder chime will turn off when the
driver’s side seatbelt is buckled or it will turn off auto- matically after six seconds. „ SRS airbag system warning light
When the ignition switch is turned to the “ON” position,
the SRS airbag system warning light will come on for
about six seconds and go out. This shows the SRS
frontal airbag and SRS side airbag (if equipped) and
seatbelt pretensioners are in normal operation.
If this light comes on while driving or remains illuminat-
ed even after a period of about 6 seconds from when
the ignition has been turned on, it may indicate that the
SRS frontal airbag system or SRS side airbag system
(if equipped) or seatbelt pretensioner system is not
working properly. Contact your nearest SUBARU
dealer immediately.

and come on steadily after several driving trips. You
should have your vehicle checked by an authorized
SUBARU dealer immediately. „
Charge warning light
If this light comes on when the engine is running, it
may indicate that the charging system is not working
properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the alternator belt. If the belt is
loose, broken or if the belt is in good condition but the
light remains on, contact your nearest SUBARU deal-
er immediately. „ Oil pressure warning light
Do not operate the engine with the oil pressure
warning light on. This may cause serious en-
gine damage.
If this light comes on when the engine is running, it
may indicate that the engine oil pressure is low and the lubricating system is not working properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the engine oil level. If the oil lev-
el is low, add oil immediately. If the engine oil is at the
proper level but the light remains on, contact your
nearest SUBARU dealer immediately. „
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. T 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.

Climate control
„
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 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 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.

Driving tips

Winter driving „Operation during cold weather
Carry some emergency equipment, such as tire
chains, a window scraper, a bag of sand, flares, a
small shovel, and jumper cables.
Check the battery and cables. Cold temperatures re-
duce battery capacity. The battery must be in good
condition to provide enough power for cold winterstarts.
Use an engine oil of proper grade and viscosity for
cold weather. Heavy summer oil will cause harder starting.
Keep the door locks from freezing by squirting them
with deicer or glycerin.
Forcing a frozen door open may damage or separate
the rubber weather strips around the door. If the door
is frozen, use hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that contains an anti-
freeze solution. Do not use engine antifreeze or other
substitutes because they may damage the paint of the
vehicle. T
Before driving your vehicle
Before entering the vehicle, remove any snow or ice
from your shoes because that could make the pedals
slippery and dangerous.
While warming up the vehicle before driving, check
that the accelerator pedal, brake pedal, and all other
controls operate smoothly.
Clear away ice and snow that has accumulated under
the fenders to avoid making steering difficult. During
severe winter driving, stop when and where it is safe
to do so and check under the fenders periodically.

length caused by attaching the trailer to your vehicle.
1) Left turn
2) Right turn
y Backing up with a trailer is difficult and takes prac-
tice. When backing up with a trailer, never accelerate
or steer rapidly. When turning back, grip the bottom of
the steering wheel with one hand and turn it to the left
for a left turn, and turn it to the right for a right turn. y If the ABS warning light illuminates while the vehicle
is in motion, stop towing the trailer and have repairs
performed immediately by the nearest SUBARU deal- er. T
Driving on grades
y Before going down a steep hill, slow down and shift
into lower gear (if necessary, use 1st gear) in order to
utilize the engine braking effect and prevent overheat-
ing of your vehicle’s brakes. Do not make sudden
downshifts.y When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating.y When driving uphill in hot weather, pay attention to
the water temperature gauge pointer (for all vehicles)
and AT OIL TEMP warning light (for AT vehicles) since
the engine and transmission are relatively prone to
overheating under these conditions. If the water tem-
perature gauge pointer approaches the OVERHEAT
zone or the AT OIL TEMP warning light illuminates,
immediately switch off the air conditioner and stop the
vehicle at the nearest safe place. Refer to the “Engine
overheating” section in chapter 9, and “Warning and
indicator lights” section in chapter 3. y If your vehicle has an automatic transmission, avoid
using the accelerator pedal to stay stationary on an
uphill slope instead of using the parking brake or foot
brake. That may cause the transmission fluid to over-
heat. Also, if your vehicle is equipped with an automat-
ic transmission, avoid driving with the gear selector le-
ver in “D” when towing a heavy trailer to prevent fluid

7. Slide the cover toward the vehicle front to remove it.
8. Remove the oil filter with an oil filter wrench.
9. Before installing a new oil filter, apply a thin coat of
engine oil to the seal.
10.Clean the rubber seal seating area of the bottom of
engine and install the oil filter by hand turning. Be
careful not to twist or damage the seal.
11.Tighten it approximately two-thirds of a turn after
the seal makes contact with the bottom of engine.
Never over tighten the oil filter because that can
result in an oil leak.
12.Reinstall the cover under the oil filter.
13.Pour engine oil through the filler neck.
Oil capacity (Guideline): 2.5 liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
3.0 liter models: 5.6 US qt (5.3 liters, 4.6 Imp qt)
The oil quantity indicated above is only a guideline.
The necessary quantity of oil depends on the quantity
of oil that has been drained. The quantity of drained oil
differs slightly depending on the temperature of the oil
and the time the oil is left flowing out. After refilling the
engine with oil, therefore, you must use the dipstick to
confirm that the level is correct.
14.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal and drain plug.
15.Run the engine until it reaches the normal operat-
ing temperature. Then stop the engine and wait a few
minutes to allow the oil drain back. Check the oil level
again and if necessary, add more engine oil.

API Service label
1) Indicates the oil quality by API designations
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving capabilities
In choosing an oil, you want the proper quality and vis-
cosity, as well as one that will add to fuel economy.
The following table lists the recommended viscosities
and applicable temperatures.
When adding oil, different brands may be used togeth-
er as long as they are the same API classification and
SAE viscosity as those recommended by SUBARU. SAE viscosity number and applicable temperature
*: 5W-30 is preferred.
Engine oil viscosity (thickness) affects fuel economy.
Oils of lower viscosity provide better fuel economy.
However, in hot weather, oil of higher viscosity is re-
quired to properly lubricate the engine. „ Recommended grade and viscosity
under severe driving conditions
If the vehicle is used in desert areas, in areas with very
high temperatures, or used for heavy-duty applica-
tions such as towing a trailer, use of oil with the follow-
ing grade and viscosities is recommended.

Cooling system
Never attempt to remove the radiator cap until
the engine has been shut off and has cooled
down completely. Since the coolant is under
pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap is re-
moved.
yThe cooling system has been filled at the fac-
tory with a high quality, corrosion-inhibiting,
year-around coolant which provides protection
against freezing down to –33 °F (–36 °C). For
adding, use genuine SUBARU coolant or an
equivalent: a mixture of 50% soft water and 50%
ethylene-glycol basis coolant. Use of improper
coolants may result in corrosion in the cooling
system. It is important to maintain protection
against freezing and corrosion, even if freezing
temperatures are not expected. Never mix dif-
ferent kinds of coolant. y Do not splash the engine coolant over paint-
