    ADJUSTMENT - FRONT FOG LAMP UNIT

    VEHICLE PREPARATION FOR FOG LAMP ALIGNMENT
    [​IMG]
    (1) Repair or replace any faulty or damaged components that could hinder proper lamp alignment.
    (2) Verify proper tire inflation.
    (3) Clean the front fog lamp lenses.
    (4) Verify that the cargo area is not heavily loaded.
    (5) The fuel tank should be Full. Add 2.94 kilograms (6.5 pounds) of weight over the fuel tank for each estimated gallon of missing fuel.

    FOG LAMP ALIGNMENT
    [​IMG]
    Prepare an alignment screen as illustrated. A properly aligned front fog lamp will project a pattern on the alignment screen 100 millimeters (4 inches) below the fog lamp centerline and straight ahead of the lamp.
    (1) Position the vehicle on a level surface perpendicular to a flat wall 7.62 meters (25 feet) away from the front of the front fog lamp lens (Fig. 16). If necessary, tape a line on the floor 7.62 meters (25 feet) away from and parallel to the wall.
    (2) Measure up on the wall 1.27 meters (5 feet) from the floor and tape a vertical line on the alignment screen at the centerline of the vehicle. Sight along the centerline of the vehicle (from the rear of the vehicle forward) to verify the accuracy of the centerline placement.
    (3) Rock the vehicle from side-to-side three times to allow the suspension to stabilize, then jounce the front suspension three times by pushing downward on the front bumper and releasing. Measure the distance from the center of the front fog lamp lens to the floor. Transfer this measurement to the alignment screen and tape a horizontal line on the wall at this mark. This line will be used for up-and-down
    adjustment reference.
    (4) Measure the distance from the centerline of the vehicle to the center of each front fog lamp being aligned. Transfer these measurements to the alignment screen and tape a vertical line this distance to each side of the vehicle centerline. These lines will be used for left/right reference.
    (5) Rotate the front fog lamp adjusting screws to adjust the beam height as required (Fig. 17).
