Horizontal aim adjustment 1. 2. Open the hood and locate the horizontal indicator and adjusting screw. Use a 4mm wrench to turn the horizontal adjusting screw until the reference mark on the reflector extension aligns with the "0" reference mark on the horizontal indicator when viewed from directly above. If the vehicle has been in an accident requiring the front end of the vehicle to be repaired, the horizontal indicator should be recalibrated by a servicing facility using the Taurus/Sable Service Manual instructions. With the hood open, locate the bubble level vertical aim indicator. It is visible when viewed from above and to the rear of the headlamp. With the vehicle on a level surface, use a 4mm wrench to turn the vertical aim adjustment screw (outboard screw) located on the back of the lamp assembly clockwise or counterclockwise until the bubble in the spirit level is centered when viewed from directly above the bubble. Close the hood. Vertical aim adjustment 1. 2. 3. If the vehicle is on a downward or upward slope of not more than 1.2˚, the VHAD's bubble level can be used to correct for the effects of the surface slope, provided that the slope is accurately known. Each graduation of the bubble level represents 0.19˚ of downward or upward slope. To correct for the effects of a surface slope, turn the vertical aim adjustment screw until the bubble is centered at a position corresponding to the slope of the surface. 319
