The manufacturer recommends cleaning the drain holes every 15,000 km. When operating the vehicle on country roads, carry out this operation more often.
During operation, moisture accumulates in the cavities of thresholds and doors, causing corrosion. This moisture is removed through drainage holes located at the bottom of the thresholds and doors. Each threshold and each side door has three drainage holes. They are constantly clogged with dirt, that is, they require cleaning.
Recommendation: Clean the drain holes before washing the car.
Location of drainage holes
Clean the drain holes in the thresholds with a screwdriver or wire.
In the same way, clean the drainage holes in the doors.
