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 reliable opera-tion. Most common causes of corrosion
The most common causes of corrosion are:
1. The accumulation of moisture retaining dirt and debris in body
panel sections, cavities, and other areas.
2. Damage to paint and other protective coatings caused by graveland 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 corrosion to parts of the vehicle
which cannot dry quickly due to lack of proper ventilation. To help prevent corrosion
Wash the vehicle frequently. If you drive on salted roads in the winter
or if you live in a coastal area, you should flush the underbody with
fresh water frequently.
After the winter has ended, it is recommended that the underbody be
given a very thorough washing.

10-6Before 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 needassistance. 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 causedampness.
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 lubri-
cated periodically.
Cleaning the interior
Use a vacuum cleaner to get rid of the dust and dirt. Wipe the vinyl areas with a clean, damp cloth. Seat fabric
Remove loose dirt, dust or debris with a vacuum cleaner. If the dirt is
caked on the fabric or hard to remove with a vacuum cleaner, use asoft blush then vacuum it.
Wipe the fabric surface with a tightly wrung cloth and dry the seat
fabric thoroughly. If the fabric is still dirty, wipe using a solution of mild
soap and lukewarm water then dry thoroughly.
If the stain does not come out, try a commercially-available fabric

cleaner. Use the cleaner on a hidden place and make sure it does not
affect the fabric adversely. Use the cleaner according to its instruc-tions.
Leather seat materials
The leather used by SUBARU is a high quality natural product which
will retain its distinctive appearance and feel for many years with
proper care.
Allowing dust or road dirt to build up on the surface can cause the
material to become brittle and to wear prematurely. Regular cleaning
with a soft, moist, natural fiber cloth should be performed monthly,
taking care not to soak the leather or allow water to penetrate thestitched seams.A mild detergent suitable for cleaning woolen fabrics may be used to
remove difficult dirt spots, rubbing with a soft, dry cloth afterwards to
restore the luster. If your SUBARU is to be parked for a long time in
bright sunlight, it is recommended that the seats and headrests be
covered, or the windows shaded, to prevent fading or shrinkage.
Minor surface blemishes or bald patches may be treated with a com-
mercial leather spray lacquer. You will discover that each leather seatsection will develop soft folds or wrinkles, which is characteristic of
genuine leather. Synthetic leather upholstery
The synthetic leather material used on the SUBARU may be cleaned
using mild soap or detergent and water, after first vacuuming or
brushing away loose dirt. Allow the soap to soak in for a few minutes
and wipe off with a clean, damp cloth. Commercial foam-type clean-ers suitable for synthetic leather materials may be used when neces-
sary. NOTE Strong cleaning agents such as solvents, paint thinners, window
cleaner or gasoline must never be used on leather or syntheticinterior materials.

Maintenance schedule
The scheduled maintenance items required to be serviced at regular in-
tervals are shown in the
“Warranty and Maintenance Booklet ”.
For details of your maintenance schedule, read the separate “Warranty
and Maintenance Booklet ”.
Maintenance precautions
When maintenance and service are required, it is recommended that all
work be done by an authorized SUBARU dealer.
If you perform maintenance and service by yourself, you should familiar-
ize yourself with the information provided in this section on general main-
tenance and service for your SUBARU.
Incorrect or incomplete service could cause improper or unsafe vehicle
operation. 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 apparatus.Attempting to do so will result in transmission damage and inuncontrolled 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 avoid injury when working on the ve-
hicle. Remember that some of the materials in the vehicle may behazardous if improperly used or handled, for example, batteryacid. Your vehicle should only be serviced by persons fully compe-
tent to do so. Serious personal injury may result to persons not
experienced in servicing vehicles.

11-4
Always use the proper tools and make certain that they are
well maintained. Never get under the vehicle supported only by a jack. Always
use a 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 in your eyes. If something does get in your eyes, thorough-
ly wash them out with clean water. Do not tamper with the wiring of the SRS airbag system or
seatbelt pretensioner system, or attempt to take its connectorsapart, as that may activate the system or it can render it inopera-tive. The wiring and connectors of these systems are yellow for
easy identification. NEVER use a circuit tester for these wiring. If your SRS airbag or seatbelt pretensioner needs service, con-
sult your nearest SUBARU dealer. Before checking or servicing in the engine compart- ment
Always stop the engine and set the parking brake firmly to pre-
vent the vehicle from moving. Always let the engine cool down. Engine parts become very
hot when the engine is running and remain hot for some time af-ter the engine is stopped. Do not spill engine oil, engine coolant, brake fluid or any other
fluid on hot engine components. This may cause a fire. Always remove the key from the ignition switch. When the
ignition switch is in the “ON” position, the cooling fan may oper-
ate suddenly even when the engine is stopped.
