ADJUST HEADLIGHT AIMING
1. Remove any covers necessary to access the headlight adjusters.
2. Adjust the low beam:
  1. Text in Illustration
    
    *1 Aiming Screw A
    
    Adjust the aim vertically:
    
    Adjust the aim of each low beam to the specified range by turning each aiming screw A with a screwdriver.
    
    Note
    
    The final turn of the aiming screw should be made in the clockwise direction. If the screw is tightened excessively, loosen it and then retighten it, so that the final turn of the screw is in the clockwise direction.
    Tech Tips
    
    Even though the low beam light and the high beam light on each side have separate reflectors, for the vertical axis, adjusting the aim on the low beam to the correct position should also result in the high beam adjustment being correct. However, check and adjust both beams just to make sure.
    
    When adjusting the vertical axis of the low beam, the horizontal axis will also change. It is necessary to adjust the vertical position first, and then correct the horizontal position.
    
    Since the aiming screw for the low beam light and the aiming screw for the high beam light have a structure that connects them, when adjusting the vertical axis of the low beam, the vertical axis of the high beam also moves.
    
    The headlight aim for the LH side moves down and to the right when turning the aiming screw clockwise, and moves up and to the left when turning the aiming screw counterclockwise.
    
    The headlight aim for the RH side moves down and to the left when turning the aiming screw clockwise, and moves up and to the right when turning the aiming screw counterclockwise.
    
    Confirm the direction of rotation of the aiming screw by observing it while it is being adjusted. Due to the position of the screwdriver, the direction of rotation of the adjusting screw can be different than the direction of rotation of the screwdriver being used to adjust it.
    
    If it is not possible to correctly adjust headlight aim, check bulb, headlight unit and headlight unit reflector installation.
  2. Text in Illustration
    
    *1 Aiming Screw B
    
    Adjust the aim horizontally:
    
    Adjust the aim of each low beam to the specified range by turning each aiming screw B with a screwdriver.
    
    Note
    
    The final turn of the aiming screw should be made in the clockwise direction. If the screw is tightened excessively, loosen it and then retighten it, so that the final turn of the screw is in the clockwise direction.
    Tech Tips
    
    Since the low beam light and the high beam light on each side have separate reflectors, the high beam horizontal aim will not be adjusted even though the low beam horizontal aim is adjusted.
    
    When adjusting the vertical axis of the headlight, the horizontal axis will also change. It is necessary to adjust the vertical position first, and then correct the horizontal position.
    
    If it is not possible to correctly adjust headlight aim, check bulb, headlight unit and headlight unit reflector installation.
    
    Confirm the direction of rotation of the aiming screw by observing it while it is being adjusted. Due to the position of the screwdriver, the direction of rotation of the adjusting screw can be different than the direction of rotation of the screwdriver being used to adjust it.
