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.
J
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 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 con-
siderable 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 wa-
ter frequently.
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 com-
ponents, 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
