Head checks are no longer necessary are not an advantage of Enhanced mirror settings .
Option C is correct .
When the mirrors are set to this setting, the driver cannot see the left and right sides of the vehicle when looking in the door mirrors. This setting gives the best view of the sides of the vehicle and reduces blind spots.
Properly adjusting and using your car's side and rear view mirrors can help eliminate dangerous blind spots and keep your car out of the way of oncoming traffic.
Lean to your left and rest your head on the window. Adjust the driver's side mirror so that only part of the side of the car is visible from this position. Lean towards the center console to the right and adjust the passenger side mirror so that you can barely see the sides of the car from this position.
