Headlamp Aiming; Bulb Replacement; Halogen Bulbs - Chevrolet Impala 2007 Impala Owner's Manual

Headlamp Aiming

Headlamp aim has been preset at the factory
and should need no further adjustment.
However, if your vehicle is damaged in an
accident, the headlamp aim may be affected.
Aim adjustment to the low-beam headlamps
may be necessary if it is difficult to see the
lane markers (for horizontal aim), or if oncoming
drivers flash their high-beam headlamps at
you (for vertical aim).
If you believe your headlamps need to be
re-aimed, it is recommend that you take the
vehicle to your dealer for service.
