lAdjust headlamps so that main axis of light is parallel to cen-
ter line of body and is aligned with point P shown in illustra-
tion.
lFigure shows headlamp aiming pattern for driving on right
side of road; for driving on left side of road, aiming pattern is
reversed.
lDotted lines to point P in illustration show center of head-
lamp.
lElbow point for LHD models must be in 125 mm (4.92 in) to
the right form point P.
Elbow point for RHD models must be in 125 mm (4.92 in) to
the left form point P.
lBasic illuminating area for adjustment should be within the
range shown in the figure. Adjust headlamps accordingly.
CAUTION:
Be sure aiming switch is set to “0” when preforming aiming
adjustment.
