Take the same measurement as noted in point 2. Draw a horizontal line as wide as the car on the wall.
Switch on the fog lights.
Screen off the fog light not being set.
When the light setting is correct, the base line of the light image should match the horizontal line on the wall.
Adjust the light image vertically until the base line matches the horizontal line on the wall.
