3. Anti-Lock Braking System: The symbol illuminates letters ABS inside a circle. When this light pops up, it shows that there is an issue with your anti-lock brake.

If this pops up while driving, pull over carefully and get it checked right away. Make sure you check your parking brake first, as leaving it engaged will also cause this light to come on.

How Do You Adjust the Light on a Ford Flex?

To adjust the lights on your Ford Flex, follow the following steps;

  • Park your Flex about 4-5 feet from a light-colored wall.
  • Verify your tire pressure cautiously.
  • Verify that the height adjustment knob for the lights is set to 0.
  • Try doing that with a half-full tank and take out all needless weight from the vehicle, just one person should be in the driver’s seat.
  • Turn on your dipped beam and make a cross-shaped mark (one horizontal and one vertical section) in the middle of the beam that will be projected on the wall.
  • Then back your vehicle up to a distance of about 25 Feet.
  • Open your hood; identify the screws for horizontal and vertical control of the headlights of your Ford Flex.
    1. The screw-on top adjusts the verticality of headlights.
    2. The one on the side controls the horizontality of the headlight.
  • Use the screws to make the horizontal adjustment; the most intense part of the beam should be a little to the right of the vertical line marked on the wall.
  • For vertical correction, you will have to use the screw to position the upper end of the beam at the level of the horizontal marking on the wall, or slightly down below.
  • Once finished, verify that the headlights setting of your Ford Flex is coherent.
  • You can go a step further to verify it after you have driven it; it may move if the adjustment screws are not well tightened.
