Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your 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 ash their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be re-aimed, it is
recommended that you take the vehicle to your
dealer/retailer for service.

Lighting
{CAUTION:

service them.
Your vehicle has HID headlamps. After your vehicle’s
HID headlamp bulb has been replaced, you may notice
that the beam is a slightly different shade than it was
