Headlamp Aiming
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, we recommend that you
take your vehicle to the dealer for service. However, it is
possible for you to re
-
aim your headlamps by following
the procedure in the service manual for your vehicle.
