Headlamp: Adjustments

HEADLAMP ALIGNMENT

Bubble Level:

Gauge Wheel - Typical:

JX vehicle headlamps are equipped with a bubble level to aid up/down headlamp alignment. The bubble level is used to assist headlamp alignment when compensating for vehicle ride height changes due to heavy luggage compartment loads. The bubble level cannot be calibrated, the headlamp must be replaced if bubble level vial is faulty. A gauge wheel is located on the top of the headlamp module to assist left/right alignment.

ADJUSTMENTS
Headlamp Alignment Preparation
1. Verify headlamp dimmer switch and high beam indicator operation.
2. Inspect and correct damaged or defective components that could interfere with proper headlamp alignment.
3. Verify proper tire inflation.
4. Clean headlamp lenses.
5. Verify that luggage area is not heavily loaded.
6. Fuel tank should be FULL. Add 2.94 kg (6.5 lbs.) of weight over the fuel tank for each estimated gallon of missing fuel.

HEADLAMP ADJUSTMENT USING ALIGNMENT SCREEN
Alignment Screen Preparation

Headlamp Alignment Screen:

1. Position vehicle on a level surface perpendicular to a flat wall 7.62 meters (25 ft.) away from front of headlamp lens.
2. If necessary, tape a line on the floor 7.62 meters (25 ft.) away from and parallel to the wall.
3. From the ground 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 ground. 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
A properly aimed low beam headlamp will project the center of the low beam hot spot on the alignment screen 190 mm (7.5 in.) below the headlamp center line. The side-to-side low beam hot spot should be 127 mm (5 in.) right of headlamp center line. The preferred headlamp alignment is 0 (± 0.76 °) for the up/down adjustment as indicated on bubble level. Preferred left/right alignment is 0 (± 0.76 °) as indicated on the gauge wheel. The high beam headlamps cannot be aligned. The high beam pattern should be correct when the low beams are aligned properly.

NOTE: The bubble level and gauge wheel is calibrated before the headlamp is installed in the vehicle. The bubble level cannot be calibrated without damaging the headlamp module. If bubble level is faulty, replace headlamp module.

Headlamp Alignment Screws:

To adjust headlamp alignment, rotate alignment screws to achieve the specified low beam hot spot pattern.
