During operation, moisture accumulates in the cavities of the thresholds, doors and trunk lid, causing corrosion. Drainage holes located below the thresholds (under the plastic protection of the thresholds), doors and in the trunk lid serve to remove moisture. They are constantly clogged with dirt, so clean them at each maintenance (every 20,000 km). When operating the car on country roads, perform this operation more often.
Note: Clean the drain holes before washing your vehicle.
You will need: a screwdriver or a thin wooden stick.
1. Clean the drainage holes in the front doors.
2. Similarly, clean the drainage holes in the rear doors and tailgate.
3. We also recommend removing the threshold protection, washing the thresholds underneath and cleaning the drainage holes.
