Headlamp Aiming
Your vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has been
pre
-
set at the factory and should need no further
adjustment. This is true even though your vertical and
horizontal aim indicators may not fall exactly on the “0”
(zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment may be necessary
if it is difficult to see lane markers (for horizontal aim),
or if oncoming drivers flash their high beams at you (for
vertical aim). If you believe your headlamps need to be
re
-
aimed, we recommend that you take it to your dealer
for service; however, it is possible for you to re
-
aim
your headlamps as described in the following procedure.
