2. If necessary, tape a line on the floor 7.62 meters (25 ft.) away from and parallel to the wall.
3. From the floor up 1.27 meters (5 ft.), tape a line on the wall at the center line of the vehicle. Sight along the center line of the vehicle (from rear of vehicle forward) to verify accuracy of the line placement.
4. Rock vehicle side-to-side three times to allow suspension to stabilize.
5. Jounce front suspension three times by pushing downward on front bumper and releasing.
6. Measure the distance from the center of headlamp lens to the floor. Transfer measurement to the alignment screen (with tape). Use this line for up/down adjustment reference.
7. Measure distance from the center line of the vehicle to the center of each headlamp being aligned.Transfer measurements to screen (with tape) to each side of vehicle center line. Use these lines for left right adjustment reference.

Fog Lamp Alignment

Lamp Alignment Screen:

Disengage the wire connectors from the back of the headlamp bulbs to disable the headlamps. This will allow a more accurate projection reading of the fog lamps. Turn on the headlamp switch and actuate the fog lamp switch. A properly aligned fog lamp will project a pattern on the alignment screen 100 mm (4 in.) below the fog lamp centerline and straight ahead.
