Body electrical system / Headlamps - alignment


1 It is recommended that the headlamp alignment is carried out by a Ford dealer using specialist beam setting equipment. However, in an emergency the following procedure will provide an acceptable light pattern.

2 With the vehicle unladen, with a full tank of fuel, and with the tyres correctly inflated, position the vehicle approximately 10 metres (33 feet) in front of, and at right-angles to, a wall or garage door.

3 Draw a vertical line on the wall corresponding to the centre line of the car.

The position of the line can be ascertained by marking the centre of the front and rear screens with crayon then viewing the wall from the rear of the car.

4 Complete the lines shown (see illustration).
