- Power on the headlight tester.
- Use the knobs on the base of the headlight aimer to adjust the tester level.
-
Align the headlight aimer perpendicular
to the vehicle.
NoteUse visor/laser to line up the tester perpendicular to the axis between the hood strut furthest fender bolts. If the headlight aimer can move between the RH and LH headlights while maintaining the same laser angle projected onto the hood struts, it is set correctly (perpendicular) to the vehicle.
- Initiate test on the headlight aimer: select .
-
Select vehicle model on the headlight
aimer:
- If headlight type is ECE or SAE, set to Car
