Lincoln Aviator: Pedestrian Protection - Plug-In Hybrid Electric Vehicle (PHEV)
Due to the quiet operation of hybrid and
electric vehicles at low speeds, the system

The system is on when your vehicle is
running and not in park (P). Some sound may
be audible in the passenger compartment.
WARNING: Modifying or adding
equipment to the front end of your vehicle
(including hood, bumper system, frame,
front end body structure, tow hooks and
hood pins) may affect the performance of
the airbag system, increasing the risk of
injury...
