Underbody
In areas where road salt is used in winter, the underbody must be cleaned regularly.
This will prevent dirt and salt from building up and causing the acceleration of corrosion on the underbody and suspension.
Before the winter period and again in the spring, the underseal must be checked and, if necessary, re-treated.
