HID Headlamps, Performing Basic Setting

Since the automatic Headlamp Range Control does not have a manual adjustment, the basic setting procedure must be performed to adjust the headlights.

If the basic setting for the automatic Headlamp Range Control is not performed, the mechanical adjustment in the headlight housing will be damaged.

After the headlights are adjusted, the DTC memory must be checked. For that reason, this procedure must be strictly adhered to.

-- Connect the diagnostic tester. Refer to VEHICLE TESTER, CONNECTING .
