Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low-beam
headlamps may be necessary if it is difficult to see the
lane markers (for horizontal aim), or if oncoming drivers
ash their high-beam headlamps at you (for vertical aim).
If you believe your headlamps need to be re-aimed, we
recommend that you take your vehicle to your dealer for
service.

Your vehicle may have HID headlamps. After your
vehicle’s HID headlamp bulb has been replaced, you
