2429412 - 5540B38 headlamp/light cluster light beam - position
Prepare the vehicle complete with spare wheel, tools, fluids, fuel reserve and driver on board.Check that the tyre inflation pressure is correct.Place the headlamp alignment switch in position '0'.Position the vehicle on a flat surface, perpendicular to a screen or an opaque surface, 10 metres away, which contains the following lines.1. V - V: vertical line corresponding to the trace of the plane of symmetry of the vehicle.2. C - C: traces of the vertical planes passing through the reference centres of the light clusters.3. HC - HC: horizontal line corresponding to the height from the ground of the reference centres for the light clusters.4. AC - AC: horizontal line 12 cm below the HC - HC line.5. Lines inclined at 15° as illustrated in the diagram.
Switch on the dipped headlamps.1. Vertical alignment. Adjust the light cluster's vertical adjustment
screw so that the horizontal section of the demarcation line between
the area which is dark and the area which is lit up by the light
beam coincides with the line AC - AC on the screen.2. Horizontal alignment. Adjust the light cluster's horizontal adjustment
screw so that the point where the two horizontal and inclined demarcation
lines intersect coincides with the point where lines C - C and AC -
AC intersect on the screen.
