Do not use a pointed object such as a screwdriver to open the cover in the dashboard. You could damage the dashboard or the cover.
Make sure that no moisture can enter the fuse box when the cover is open.
When closing the cover, make sure that it is lying correctly on the fuse box. Moisture seeping in or dirt could otherwise impair the operation of the fuses.
