  1. HEADLIGHT AIM ONLY NOTE: For adjustment of headlight aiming, perform with Low beam. The Low-beam light or High-beam light is a unit, if either aiming of them is proper, the other must also be proper. However, check both beams just to be sure. Prepare vehicle in the following conditions. Any damages or deformations does not exist at the body around the headlight. Fuel is full. The tire inflation pressure is the specified level. Inspect with the vehicle parked at the level surface. Have a person with standard weight sit on the driver seat. Bounce the vehicle up and down to stabilize the suspension to the normal position. Prepare a thick white paper (Draw a based line). NOTE: Use to stand the paper perpendicular. The based line differs in "Low-beam inspection" and "High-beam inspection". H line (Headlight height) For the vehicle, when checking the height from the ground to the center mark of Low-beam (or High-beam), draw a horizontal line A-B at the height of Low-beam (or High-beam). V LH line, V RH line (Center mark position of right and left head lamp) Draw a V LH line and V RH line in the width of the center mark of the right and left Low-beam (when checking High-beam, draw a V LH line and V RH line in the width of the center mark of the right and left Hi-beam). N line (Vehicle Center position) At the middle of the V LH line and V RH line, draw a line to align the center of the paper with that of the vehicle. Check the headlight aiming. Align the paper with the vehicle position. Make the distance of 3 m (9.84 ft) between the head lamp and the paper, and put the paper on the wall with the H line being at the height of the center mark. Align the center line of the vehicle with the V line on the paper, and make the center line of the vehicle and the paper 90 degrees. Start the engine of the vehicle with air suspension. Turn the headlight on and check that the aiming is between the specified value (Scheme 39)and (Scheme 40). NOTE: When checking the aiming of the High-beam, shut off the Low-beam or disconnect the Low-beam head lamp connector so that the Low-beam does not interrupt. Unlock the headlight aiming cap (Scheme 41) When adjusting the aiming in the vertical direction. Using adjusting bolt A adjust the headlight aim to the specified range. NOTE: Rotating a screwdriver clockwise makes the optical axis aim downward and rotating counter clockwise makes it up ward. When adjusting the aiming in the horizontal direction. Using adjusting bolt B, adjust the headlight aim to the specified range. Lock the headlight aiming cap (Scheme 43) NOTE: After adjusting the headlight aim by using the adjusting bolt B, turn the adjusting bolt cover to lock the bolt. If the bolt cannot be locked by turning the cover, it means that the headlight aim is not adjusted correctly.
