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 oper-
ation.
„ Most common causes of corrosion
The most common causes of corrosion are:
1. The accumulation of moisture retaining dirt and de-
bris 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 corrosion to parts of
the vehicle which cannot dry quickly due to lack of
10-4
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 frequent-
ly.
After the winter has ended, it is recommended 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, steer-
ing system, floor pan, and fenders. If any of them are
found to be rusted, they should be given an appropri-
ate 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 ac-
cumulation 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
