    Fastening the Seatbelts

    The front outboard and rear safety restraints in the vehicle are combination lap and shoulder belts.

    Insert the belt tongue into the proper buckle (the buckle closest to the direction the tongue is coming from) until you hear a snap and feel it latch. Make sure that you securely fasten the tongue in the buckle.

    Lincoln Aviator. Fastening the Seatbelts

    To unfasten, press the release button and remove the tongue from the buckle.
