Important: Use this procedure only when suitable test
equipment is unavailable.
Set up a screen or use a vertical, with a flat horizontal
wall. Park the vehicle immediately in front of the screen or wall and mark the following
lines:
•
A vertical centre-line (2) that corresponds to the centre of the vehicle.
•
A horizontal line (1) that corresponds to the centre of the front fog
lamp bulb.
Turn on the front fog lamps to check whether the marks are correctly positioned.
Reverse the vehicle straight back so the front is five metres in front
of the screen or wall, ensuring the centre of the vehicle is aligned with the vertical
centre-line mark (3) on the screen.
Turn on the front fog lamps. Aim each front fog lamp
with the cut-off line (2) 100 mm (V) below the front fog lamp horizontal centre-line
(1).
