2010 SUBARU LEGACY maintenance

CAUTION
Never use any temporary spare tire
other than the original. Using other
sizes may result in severe mechan-
ical damage to the drive train of yourvehicle.
The temporary spare tire is smaller and
lighter than a conventional tire and is
designed for emergency use only. Re-
move the temporary spare tire and re-
install the conventional tire as soon as
possible because the spare tire is de-
signed only for temporary use.
Check the inflation pressure of the tem-
porary spare tire periodically to keep the
tire ready for use. The correct pressure is
60 psi (420 kPa, 4.2 kgf/cm
2) .
When using the temporary spare tire, note
the following precautions. . Do not exceed 50 mph (80 km/h).
. Do not put a tire chain on the temporary
spare tire. Because of the smaller tire size,
a tire chain will not fit properly. . Do not use two or more temporary
spare tires at the same time.. Do not drive over obstacles. This tire
has a smaller diameter, so road clearance
is reduced.
1) Tread wear indicator bar
2) Indicator location mark
. When the wear indicator appears on
the tread, replace the tire. . The temporary spare tire must be used
only on a rear wheel. If a front wheel tire
gets punctured, replace the wheel with a
rear wheel and install the temporary spare
tire in place of the removed rear wheel. Maintenance tools
Your vehicle is equipped with the following
maintenance tools. .

10-4Appearance care
Corrosion protection
Your SUBARU has been designed and
built to resist corrosion. Special materials
and protective finishes have been used on
most parts of the vehicle to help maintain
fine appearance, strength, and reliableoperation. &Most common causes of corrosion
The most common causes of corrosion are:
1. The accumulation of moisture retain-
ing dirt and debris in body panel sections,
cavities, and other areas.
2. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor accidents.
Corrosion is accelerated on the vehicle when:
1. It is exposed to road salt or dust
control chemicals, or used in coastal
areas where there is more salt in the air,
or in areas where there is considerable
industrial pollution.
2. It is driven in areas of high humidity,
especially when temperatures range just
above freezing.
3. Dampness in certain parts of the
vehicle remains for a long time, even though other parts of the vehicle may be
dry.
4. High temperatures will cause corro-
sion to parts of the vehicle which cannot
dry quickly due to lack of proper ventila-tion.
& To help prevent corrosion
Wash the vehicle regularly to prevent
corrosion of the body and suspension
components. Also, wash the vehicle
promptly after driving on any of the
following surfaces. . roads that have been salted to prevent
them from freezing in winter. mud, sand, or gravel
. coastal roads
After the winter has ended, it is recom-
mended that the underbody be given a
very thorough washing.
Before the beginning of winter, check the
condition of underbody components, such
as the exhaust system, fuel and brake
lines, brake cables, suspension, steering
system, floor pan, and fenders. If any of
them are found to be rusted, they should
be given an appropriate rust prevention
treatment or should be replaced. Contact
your SUBARU dealer to perform this kind
of maintenance and treatment if you need assistance.
Repair chips and scratches in the paint as
soon as you find them.
Check the interior of the vehicle for water
and dirt accumulation under the floor mats
because that could cause corrosion.
Occasionally check under the mats to
make sure the area is dry.
Keep your garage dry. Do not park your
vehicle in a damp, poorly ventilated
garage. In such a garage, corrosion can
be caused by dampness. If you wash the
vehicle in the garage or put the vehicle
into the garage when wet or covered with
snow, that can cause dampness.
If your vehicle is operated in cold weather
and/or in areas where road salts and other
corrosive materials are used, the door
hinges and locks, trunk lid lock, and hood
latch should be inspected and lubricated
periodically.

Maintenance schedule
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the“Warranty and Main-
tenance Booklet ”.
For details about your maintenance sche-
dule, read the separate “Warranty and
Maintenance Booklet ”. Maintenance precautions
When 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
section 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
vehicle must NEVER be per-
formed on a single two-wheel
dynamometer or similar appara-
tus. Attempting to do so will
result in transmission damage
and in uncontrolled vehicle
movement and may cause an
accident or injuries to persons
nearby.
. Always select a safe area when
performing maintenance on yourvehicle. .
Always be very careful to avoid
injury 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, batteryacid.
. 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 wellmaintained.
. Never get under the vehicle sup-
ported only by a jack. Always use
safety stands to support thevehicle.
. 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 Maintenance and service

11-4Maintenance and service
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. NEVER use a circuit
tester for these wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer. &
Before checking or servicing
