which are under the hood near each headlamp
assembly.
The adjustment screw can be turned with a
6 mm hex socket.

headlamp beam is aimed to the horizontal tape
line. If you turn it clockwise, it will raise the
beam and if you turn it counterclockwise, it will
lower the beam.
The top edge of the cut-off should be
positioned at the bottom edge of the horizontal
tape line.

tape line. The lamp on the left (A) shows
the correct headlamp aim. The lamp on the
right (B) shows the incorrect headlamp aim.
