Headlamp Aiming
The aim of your vehicle's headlamps can be adjusted by
using aim tips located on the outer surface of the lens.
-
The aim has been pre set 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
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, it is recommended that
you take your vehicle to the dealer for assistance.
