Before starting to drive, it is essential to **adjust the rearview mirrors** manually or automatically. This is crucial because the mirrors allow the driver to see what is happening behind and on the sides of the vehicle, which is essential for safe driving.

- **Properly positioned mirrors**: When looking at the interior rearview mirror, you should be able to see all four edges of the rear window. In the side mirrors, you should see the road, vehicles coming from behind, and those on the sides. Additionally, by slightly turning your neck, you should see a part of the rear of your vehicle.


- **Importance of mirrors**: During the journey, it is necessary to constantly check the mirrors to be aware of what is happening around the vehicle. This is part of defensive driving, as it helps prevent accidents by allowing you to see vehicles approaching or in blind spots.

Therefore, adjusting the rearview mirrors is an essential step before starting to drive, as it ensures that you can properly observe the surroundings and react in time to any situation on the road.
