    3. Follow the prompts on the touchscreen to calibrate the headlights. Calibration is complete when all 4 checks have transitioned from "red" to "green".
      NOTE: The calibration drive can take up to 2 km.
      NOTE: To ensure an accurate calibration:
      • After turning on the drive rails, wait for at least 1 second before switching to Drive  .
      • Close all vehicle doors and do not open the doors while performing the calibration drive.
      • After stopping the vehicle, wait at least 1 second before opening the doors.
      • Do not drive the vehicle in reverse for more than 10 meters. If this is unavoidable due to garage logistics, start the headlight calibration after the vehicle has exited the garage.
    4. After headlight calibration is complete, the headlights can be adjusted. Continue to the next step.
  2. Park the vehicle on a level surface.
  3. Make sure that all 4 tires are inflated to specification.
  4. Open the front trunk hood.
  5. Turn on the headlights.
  6. Position 75 kg of ballast in the driver seat.
  7. Position the headlight tester tool ~11 in. (30 cm) from the front of the LH headlight lens.
  8. Adjust the height of the headlight tester tool to ~27.5 in. (70 cm) above the ground to align with the center point of the headlamp.
  9. Connect the headlight tester tool to an electrical outlet, and then turn on the headlight tester tool.
  10. Adjust the knobs on the base of the headlight tester tool until the tool is leveled, as indicated by the bubble gauge on the tool.
    NOTE: The bubble must be entirely inside of the center ring in order to properly align the headlights.
  11. Turn on the alignment laser near the top of the tool, and then rotate the tool as necessary to align the laser with the base of both hood struts.
