details about your maintenance schedule,

Maintenance precautionsWhen maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service by
yourself, you should familiarize yourself
with the information provided in this sec-
tion on general maintenance and service
for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
WARNING
.Testing of an All-Wheel Drive
model must NEVER be performed
on a single two-wheel dynam-
ometer or similar apparatus. At-
tempting to do so will result in
transmission damage and in un-
controlled vehicle movement and
may cause an accident or injuries
to persons nearby.
.Always select a safe area when
performing maintenance on your
vehicle.
.Always be very careful to avoidinjury when working on the vehi-
cle. Remember that some of the
materials in the vehicle may be
hazardous if improperly used or
handled, for example, battery
acid.
.Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
.Always use the proper tools and
make certain that they are well
maintained.
.Never get under the vehicle sup-
ported only by a jack. Always use
safety stands to support the
vehicle.
.Never keep the engine running in
a poorly ventilated area, such as
a garage or other closed areas.
.Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
.Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only
by your SUBARU dealer.
.Wear adequate eye protection to
guard against getting oil or fluids

CAUTION
.For models except STI, be careful
not to touch the engine oil filter
when removing the oil filler cap.
Doing so may result in a burn, a
pinched finger, or may cause
some other injury.
.Use only engine oil with the
recommended grade and vis-
cosity.
.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. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is
correct.
For models STI, just after driving or while
the engine is warm, the engine oil level
reading may be in a range between the
upper level and the notch mark. This is
caused by thermal expansion of the
engine oil.
NOTETo prevent overfilling the engine oil, do
not add any additional oil above the
upper level when the engine is cold.&Changing the oil and oil filterChange the oil and oil filter according to
the maintenance schedule in the“War-
ranty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in
the maintenance schedule when driving
on dusty roads, when short trips are
frequently made, or when driving in ex-
tremely cold weather.NOTE.Changing the engine oil and oil filter
should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil filter.
Fully trained mechanics are on standby
at a SUBARU dealer to utilize the
special tools, spare parts and recom-
mended oil for this work, and also, used
oils are properly disposed of.
.If performing oil replacement your-
self, observe the local regulations and
dispose of waste oil properly.
&Recommended grade and
viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to“Engine oil”F12-4.NOTEEngine 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.

!Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.NOTE.Each quantity indicated here is only a guideline. The necessary quantity for replacement may differ slightly depending on
the temperature and other factors.
.In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy. Oils of lower
viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the
engine. The following table lists the recommended viscosities and applicable temperatures.
.When adding oil, you may use different brands together as long as they are the same API classification and SAE viscosity
as those recommended by SUBARU.

optimum engine performance and pro-
tection. Conventional oil may be used if
synthetic oil is unavailable.
*: If 5W-30 synthetic oil is not available,
5W-40 conventional oil may be used if
replenishment is needed but should be
changed to 5W-30 synthetic oil at the
next oil change.
