Headlamp Aiming
Your vehicle has high intensity discharge (HID)
visual optical aiming type headlamps. The aim has
been preset at the factory and should need no
further adjustment. If you suspect that the
headlamps need to be reaimed, it is recommended
that you contact your dealer for service. However,
it is possible for you to re-aim your headlamps
as described in the following procedure.
Notice: To make sure your headlamps are
aimed properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
