Headlamp: Adjustments
HEADLAMP ADJUSTMENT USING ALIGNMENT SCREENAlignment Screen Preparation
1. Position vehicle on a level surface perpendicular to a flat wall 7.62 meters (25 ft.) away from front of headlamp lens.
Headlamp Alignment Screen:
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. A small dot is molded into each headlamp lens signifying the center of the headlamp. Measure the distance from the center of the headlamp 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.
Headlamp Adjustment
The PL headlamp low beam pattern has a distinct horizontal cutoff line which is used to visually align the headlamps. A properly aimed headlamp will have the horizontal cutoff line of the low beam pattern centered on the low beam pattern centered on the horizontal center of headlamp line. The side to side left edge of the low beam hot spot should be located 75 mm (3 inches) to the left of the headlamp center line. The high beams on a vehicle with aero headlamps cannot be aligned. The high beam pattern should be correct when the low beams are aligned properly.
To adjust headlamp alignment, rotate alignment screws to achieve the specified low beam hot spot pattern.
