Adjust Headlights Using a Wall

  1. Position the vehicle for adjusting the headlights. The vehicle should be:
    • Located in a darkened area.
    • Parked on a level surface.
    • Perpendicular to a wall that has a white matte surface. The wall must be at least 1.8 m (6 ft) high and 3.7 m (12 ft) wide.
    • Close enough to the wall so that the headlights are positioned 10 m (32.8 ft) away.
  2. Make sure that all 4 tires are inflated to specification.
  3. Open the front trunk hood.
  4. On the touchscreen, touch Controls  (vehicle icon), and then touch the Software  tab to display the vehicle firmware version.
    • If the vehicle is running firmware version 2018.36.8 or higher, proceed to Step  5.
    • If the vehicle is running an earlier firmware version, update the vehicle firmware to version 2018.36.8 or higher. See FIRMWARE UPDATE .
  5. On the vehicle touchscreen, touch Controls > Service > Adjust Headlamps  to enable Headlight Adjustment Mode.
  6. Turn on the headlights.
  7. Put a piece of tape on the wall 27.5 in (698 mm) from the ground to indicate where the beam should show.
  8. Measure 25 ft (7.62 m) away from the wall and put a piece of tape on the ground to indicate where the vehicle should be parked.
  9. Park the vehicle perpendicular to the wall so that the front fascia is flush with the tape that was placed on the ground in the previous step.
  10. Note the height between the ground and the center projector lens on the driver side headlight.

  11. Mark a straight line between each of the center projector lenses and the wall. At the point where each line meets the wall, mark the height that was noted in the previous step.
  12. Use the touchscreen to turn on the low beam headlights.
  13. Cover the RH headlight; make sure that all light from the right headlight is blocked.
  14. On the steering wheel, use the left scroll wheel to adjust the beam level: Target 0.00" +/- 1.0"
    CAUTION: Do not sit in the vehicle, as this will affect headlight alignment.
    NOTE: There might be a delay between the scroll wheel input and actual headlight adjustment output.
  15. Adjust the headlight so that the distance between the ground and the top right part of the beam on the wall is 27.5 in (698 mm).
