The rear-view mirror adjustments should be made with the vehicle stationary before setting off. To adjust the mirrors correctly, the driver should follow these steps: Stop the vehicle: Make sure that the vehicle is completely stationary on a flat, straight surface. Adjust the seat and backrest: Before checking the mirrors, the driver should make sure that the seat and backrest are adjusted to their normal driving position. Adjust the mirrors: With the vehicle stationary and the seat correctly adjusted, the driver should adjust the rear-view mirrors. This involves making sure that they can see properly through the interior and exterior rear-view mirrors. Interior rear-view mirror: It should allow the driver to see at least three of the four sides of the rear window with a slight movement of the eyes, without needing to move their head. Exterior rear-view mirrors: They should be adjusted so that the driver can see the minimum necessary part of the side of the vehicle in the lower half of the mirror, the road surface in the lower half, and what is situated above the road in the upper half.
