Headlamp Aiming

The vehicle has a visual optical headlamp aiming system. The aim has been preset at the factory and should need no further adjustment

However, If the vehicle is damaged in an accident, the headlamp aim may be affected and adjustment may be necessary.

If oncoming vehicles flash their main beams at you, this may also mean the vertical aim needs to be adjusted.

It is recommended that the vehicle is taken to your dealer for service if the headlamps need to be re-aimed. It is possible however, to re-aim the headlamps as described in the following procedure.

The vehicle should be properly prepared as follows:

    • The vehicle should be placed so the headlamps are 25 ft (7.6 m) from a light coloured wall or other flat surface.
    • The vehicle must have all four tyres on a perfectly level surface which is level all the way to the wall or other flat surface.
    • The vehicle should be placed so it is perpendicular to the wall or other flat surface.
    • The vehicle should not have any snow, ice or mud on it.
    • The vehicle should be fully assembled and all other work stopped while headlamp aiming is being done.
    • The vehicle should be normally loaded with a full tank of fuel and one person or 160 lbs (75 kg) on the driver seat.
    • Tyres should be properly inflated.

Headlamp aiming is done with the vehicle dipped beam headlamps. The main beam headlamps will be correctly aimed if the dipped beam headlamps are aimed properly.

  1. To adjust the vertical aim on the headlamps, complete the following:
  2. Find the aim dots on the lens of the lamp assembly.
  3. Measure the distance from the ground to the aim dot on the lamp with the bonnet in the closed position. Record the distance.
  4. At the wall or other flat surface, measure from the ground upward the recorded distance and draw or tape a horizontal line the width of the vehicle.

    5. Caution: Do not cover a headlamp to improve beam cut-off when aiming. Covering a headlamp may cause excessive heat build-up which may cause damage to the headlamp.

  5. Turn on the dipped beam headlamps and place a piece of cardboard or equivalent in front of the headlamp not being aimed. This should allow only the beam of light from the headlamp being aimed to be seen on the flat surface.
