Headlamp Alignment Preparation
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.

Alignment Screen Preparation

1. Position the vehicle on a level surface perpendicular to a flat wall 7.62 meters (25 ft.) away from the front of headlamp lens (NOTE: If necessary, tape a line on the floor 7.62 meters (25 ft.) away from, and parallel to the wall).
2. From the base of the wall, measure up 1.27 meters (5 ft.) , and 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.
3. Rock vehicle side-to-side three times to allow suspension to stabilize.
4. Jounce front suspension three times by pushing downward on front bumper and releasing.
5. 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.
6. 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.
