For trucks with a swing away spare tire carrier, you must release the carrier and swing it out of the way before lowering the tailgate. See the following illustration. Bronco tailgate operation Latch lockout system for the tailgate The tailgate is equipped with a latch lockout system which prevents you from opening it unless the glass is completely down. The lockout also prevents the glass from being raised unless the tailgate is completely latched in the closed position. RWARNING When driving your vehicle make sure that the tailgate door and window are closed to prevent exhaust fumes from being drawn into the vehicle. This will also prevent passengers and cargo from falling out. 120
