Headlamp Aiming
Headlamp aim has been preset at the factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the headlamp aim may be affected. Aim adjustment to the low-beam headlamps may be necessary if oncoming drivers flash their high-beam headlamps at you (for vertical aim).
If the headlamps need to be re-aimed, it is recommended that the vehicle be taken to a dealer for service.
