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

-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.
