Headlamp Optical Recalibration

Important note:
Recalibration of the headlamp adjustment scale is not necessary unless the complete headlamp unit is replaced, or after accident repair.





Prepare vehicle for optical recalibration as described under "HEADLAMP ADJUSTMENT" on page 1 and:

^ Park vehicle on a level surface 7.6 m (25 feet) from a vertical test screen or wall. Mark the screen or wall according to Figure 3. Using the hood star as a reference, align the vehicle centerline with the center mark on the test screen. The centerline of the vehicle must be at a 90~ angle to the test screen.

1. Optical recalibration of the vertical adjustment is not necessary as the bubble level used for adjustment is attached permanently to the headlamp reflector. Only vertical adjustment is possible as described previously.

Note:
Even when properly adjusted, tolerances in the bulb filaments may allow a slight variation in the left-to-right headlamp beam height. Such variations are not justification for replacing the headlamp unit. If desired, the bulbs may be swapped side for side. Adjustment of the bubble levels should, however, remain at the "0" mark.





2. Perform optical recalibration of horizontal adjustment by turning the headlamp horizontal adjustment screw (7, Figure 1) so that the headlamps illuminate the test screen as shown in Figure 4.

3. After recalibration, check and if necessary, loosen the screws holding the pointers (3 & 5, Figure 2). Move them so that the pointers are aligned with "0" marks on the scales (2 & 4, Figure 1). Tighten the screws and lock both the screws and pointers in place with paint seals.

4. Reinstall headlamp unit covers and access covers in crossmember.
