PROCEDURE


  1. PRECAUTION

    Note


    • Be sure to read Precaution thoroughly before servicing.

    • Handle components indoors as much as possible to prevent foreign matter from entering and adhering to headlight assembly components.

    • Do not reuse parts which have reduced fastening ability due to thread damage.

    • Do not touch the inner surface of the lens and metallic surfaces as much as possible, or they may become dirty

    • Do not allow metallic surfaces to become dirty, as such surfaces become damaged even if they are only lightly wiped with a soft cloth.

    • When installing components, make sure that the wire harness is not pinched or pulled.

    • Do not use solvent to clean components. Only clean them with a dry cloth.

    Tech Tips


    • Use the same procedure for the RH and LH sides.

    • The procedure listed below is for the LH side.
