Many lights will illuminate when you start your vehicle to make sure the
bulb works.If any light remains on after starting the vehicle, have
the respective system inspected immediately.

Illuminates briefly to ensure the
system is functional. If it comes on
after the engine is started, one of
the engine’s emission control
systems may be malfunctioning. The
light may illuminate without a driveability concern being noted and will
not require towing.

from a vertical wall or screen directly in front of it.

observe an area of high intensity
light. The top of the high intensity
area should touch the horizontal
reference line, if not, the beam will
need to be adjusted.

adjusting, you may want to block
the light from one headlamp while
adjusting the other.

wrench, turn the adjuster either
clockwise (to adjust down) or

Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to assure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.
