According to the service manual:
Each headlamp includes an integral adjustment screw to be used for static aiming of the headlamp beams.
VEHICLE PREPARATION FOR HEADLAMP ALIGNMENT
----------------------------------------------------------------
(1) Verify headlamp dimmer (multi-function) switch and high beam indicator operation.
(2) If the vehicle is equipped with headlamp leveling, be certain that the headlamp leveling switch is in the “0” position. note: this step doesnt apply to US/Canuk markets
(3) Repair or replace any faulty or damaged components that could hinder proper lamp alignment.
(4) Verify proper tire inflation.
(5) Clean headlamp lenses.
(6) Verify that cargo area is not heavily loaded.
(7) 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.
HEADLAMP ALIGNMENT SCREEN PREPARATION
----------------------------------------------------------------
Prepare an alignment screen as illustrated.
(Hrrm, this looks more like a Cherokee and less like a libby. Go figure.)
(1) Position the vehicle on a level surface perpendicular to a flat wall 7.62 meters (25 feet) away from the front of the headlamp lens for North American vehicles, or 10.0 meters (32.81 feet) away from the front of the headlamp lens for Rest-Of-World vehicles (Fig. 43). If necessary, tape a line on the floor at the appropriate distance 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 headlamp 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 headlamp 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.
HEADLAMP ADJUSTMENT
----------------------------------------------------------------
A properly aligned headlamp will project a pattern on the alignment screen from just below horizontal to 75 millimeters (3 inches) below the headlamp centerline for vehicles in North America, or from just below horizontal to 125 millimeters (5 inches) below the headlamp horizontal centerline for vehicles in Rest-Of-World.
(1) Vehicles for all markets except Japan should have the headlamp low beams selected with the dimmer (multi-function) switch during the adjustment procedure. Vehicles for the Japanese market should have the headlamp high beams selected.
(2) Cover the lens of the headlamp that is not being adjusted.
(3) Turn the adjusting screw (Fig. 44) until the top edge of the beam intensity pattern is positioned from just below horizontal to 75 millimeters (3 inches) below the headlamp horizontal centerline for vehicles
in North America, or from just below horizontal to 125 millimeters (5 inches) below the headlamp horizontal centerline for vehicles in Rest-Of-World.
