Headlamp Aiming: Notes
WARNING: This page is about a different car, the 2010 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.
Aiming of each of the headlamps is done by turning the vertical (1) adjusting screw which moves the headlamp bulb in relation to the headlamp assembly. The adjusting screw is located inboard of the front fender wheelhouse panel. The high beam will be correctly aimed if the low beam is aimed properly.
Some state and local authorities have specific requirements for aiming the headlamps. These requirements must be followed.
