Every 16,000 km or 12 months.
1. Raise and place the vehicle on supports or an inspection pit. Carefully inspect the underbody and wheel wells for damage and corrosion. Pay particular attention to the lower part of the sills, as well as closed areas where dirt can accumulate.
2. If you find corrosion and rust on any of the panels, gently press the area with the end of a screwdriver. If the rust has penetrated the entire thickness of the metal, the screwdriver will pierce the rust. This means that the panel requires serious repair or replacement.
3. If the panel corrosion is minor, clean off all rust and apply a coat of new anti-corrosion protection. For body repair details, see Chapter 11.
4. At the same time, inspect the lower body panels covered with a protective layer for damage from stones, and also check their general condition.
5. Inspect all fuel and brake lines running along the underbody for damage, rust, corrosion and leaks. Make sure they are securely clamped. Check for damage to the protective PVC coating of the lines (where applicable).
