8-6Driving tips/Winter driving
Winter driving
&Operation during cold weather
Carry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winterstarts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
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 after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.
Washer Fluid Con- centration Freezing Temperature
30% 10.4 8F( 12 8C)
50% 48F( 20 8C)
100%
49 8F( 45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block thenozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.

11-10Maintenance and service/Engine oil
thin coat of engine oil to the seal.
9. 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.
10. Tighten the oil filter by the amount
indicated in the following table after the
seal makes contact with the bottom ofengine.Oil filter color Part number Amount of
rotation
Black 15208AA100 1 rotation
Blue 15208AA12A 7/8
rotation
CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If spilled oil is not promptly
wiped up, the oil could cause afire.
11. Reinstall under cover.
12. Pour engine oil through the filler neck.
For the oil capacity (guideline), refer to “
Engine oil ”F 12-5.
The oil quantity indicated above is onlyguideline.
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 level gauge to confirm that
the level is correct.
13. Start the engine and make sure that no
oil leaks appear around the filter ’s rubber
seal and drain plug.
14. Run the engine until it reaches the
normal operating 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 engineoil.
CAUTION
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. &
Recommended grade and viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to “Engine oil ”F 12-5.
NOTE
Engine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. However,
in hot weather, oil of higher viscosity is
required to properly lubricate the en-gine. & Synthetic oil
You should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner ’s Manual. Refer to “Engine
oil ”F 12-5. Also, you must follow the oil
and filter changing intervals shown in the
Warranty and Maintenance booklet.
NOTE
Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom-

crease in temperature could cause
tread separation, and failure of the
tire(s). Possible resulting loss of
vehicle control could lead to anaccident. !Measuring and adjusting air
pressure to achieve proper in-
flation
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to
adjust the tire pressures to the
specific values. Driving even a
short distance warms up the tires
and increases the tire pressures.
Also, the tire pressures are affected
by the outside temperature. It is
best to check tire pressure out-
doors before driving the vehicle.
When a tire becomes warm, the air
inside it expands, causing the tire
pressure to increase. Be careful not
to mistakenly release air from a
warm tire to reduce its pressure. &

GAS STATION REFERENCE
& Fuel:
! Turbo models except STI
Use premium unleaded gasoline with an octane rating of 91
AKI (95 RON) or higher . If premium unleaded gasoline with an
octane rating of 91 AKI (95 RON) is not available, regular
unleaded gasoline with octane rating of 87 AKI (90 RON) or
higher may be temporarily used. For optimum engine perfor-
mance and driveability, it is required that you use premium
grade unleaded gasoline with an octane rating of 91 AKI (95
RON) or higher. ! STI
The engine is designed to operate at maximum performance using unleaded gasoline with an octane rating of 93 AKI (98
RON) or higher . If 93 AKI (98 RON) fuel is not readily available
in your area, unleaded gasoline with an octane rating of 91 AKI
(95 RON) may be used with no detriment to engine durability or
driveability. However, you may notice a slight decrease in
maximum engine performance while using 91 AKI (95 RON)
fuel. Use of 91 AKI (95 RON) fuel will not affect your warrantycoverage. &
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). Refer to “Fuel octane rating ”F 7-3.
& Fuel capacity:
16.9 US gal (64 liters, 14.1 Imp gal) & Engine oil:
Use only the following oils. . ILSAC GF-4 or GF-5, which can be identified with the ILSAC
certification mark (Starburst mark). or API classification SN or SM with the words “ENERGY
CONSERVING ”or “RESOURCE CONSERVING ”
For the complete viscosity requirements, refer to “Engine oil ”
F 12-5.
& Engine oil capacity:
Except STI models: 4.4 US qt (4.2 liters, 3.7 Imp qt)
STI models: 4.5 US qt (4.3 liters, 3.8 Imp qt)
The indicated oil quantity is only a guideline and is estimated
based on a case when the engine oil is changed with an oil
filter. After refilling the engine with oil, the oil level should be
checked using an oil level gauge. For more details about
maintenance and service, refer to “Engine oil ”F 11-8.
& Cold tire pressure:
Refer to “Tires ”F 12-9.
