Matrix Led Headlamp, Calibrating Using Headlamp Adjusting Unit: Vas5209B: Procedure
-- Align the headlamp adjusting unit :VAS5209B at the distance -a- = 100 mm to the vehicle center. Refer to the VAS5209B Owner's Manual.
-- Check the parallel alignment of the :VAS5209B to the vehicle transverse axis. To do so, align the laser beam of the :VAS5209B to the left and right front fender bolts -arrows-.
