open the hood by the lights u will see a hole wth a light symbl near it put a long screwdriver in and turn the click wheel thing that will raise/lower the whole headlight assembly. ADJUST THE LOW BEAMS BECAUSE THE WHOLE ASSEMBLY MOVES HIGHBEAMS ARE NOT AS IMPORTANT

every headlamp has two adjusting set screws. One for vertical and horizontal. They are normally a torx driver socket that will turn these screws. If you have a garage use the garage door at night to set the beams reflecting off the door. Centering the truck to a center mark on the door would be helpful when you make the adjustments. That way your headlamps should aim evenly. Please note if your driveway is not level jack up the trucks rear end to make it so. Leveling the vehicle makes the difference before any adjustments are mad
