When cleaning the fog light lens, park the vehicle on a safe place, stop the engine and confirm that the fog light lens is not hot before proceeding with the work. 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 operation. B 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 considerable industrial pollution. 2. It is driven in areas of high humidity, especially when temperatures range just above freezing. 10-4
