Corrosion protection Your vehicle is constructed with protection against corrosion.
Corrosion protection for the body consists of modern metallic protective coatings on thesheet metal, a high-quality painting process,corrosion-protected and minimized metaloverlap, and shielding plastic components,abrasion protection and supplemental rustinhibitor in exposed areas. In the chassis,exposed components of the wheel suspensionare made of corrosion-resistant cast alumi-num.
Inspection and maintenanceThe corrosion protection does not normallyrequire maintenance, but keeping the vehicleclean helps reduce the risk of corrosion. Theuse of strong alkaline or acidic cleaning fluidsshould be avoided on shiny body components.Any stone chips in the paint should betouched up as soon as they are discovered.
