Push Bumpers
Ford Motor Company does not recommend the installation of any type of push bumper.
Siren and Grille Lights
The engine cooling system relies on proper airflow through the radiator to keep the engine at its
proper operating temperature. When adding sirens and grille lights to a vehicle, make sure this
airflow is not obstructed. Reduced airflow could put additional strain on the cooling system and
shorten the operational life of related components. The cooling system also cools the electric
motors and electronics. If the coolant exceeds certain temperatures, the components will attempt
to protect themselves by limiting the power and torque available. During the installation process,
keep the placement of components away from the grille area of the vehicle.
Mounting Equipment to the Vehicle
NOTICE: Do not disable the A/C system or damage to the high-voltage traction battery
(HVTB) system may occur. The HVTB cooling system uses the cabin air to cool the HVTB.
• Do not mount equipment to the high-voltage (orange) wiring/cables, the high-voltage cover or the
HVTB cooling plenum.
• Do not mount equipment on the instrument panel between the driver and passenger air bags
due to deployment variability.
• Do not mount equipment on the instrument panel between the driver and the pedals, between
the door and the console area due to knee air bag deployment variability.
• Do not mount equipment obstructing the HVTB service disconnect located behind the rear seat
back.
• Do not remove or block the HVTB cooling plenum or ducts. These components are necessary
for the proper cooling of the HVTB.
• Do not cover any warning or vehicle labels.
NOTICE: The side impact sensor is tuned to excite based on its mass (including wiring), as
well as the host sheet metal. Any alteration to these components must be avoided.
Additions, such as padding, wire connectors, retainers, tape or fasteners of any kind should
not be used. All fasteners in this predominantly sheet metal environment should be made
of steel or a non-conductive plastic to guarantee retention and longevity. If any part of a
steel fastener is exposed to a wet area, it should be plated to resist corrosion.
• Do not mount equipment to the A, B or C-pillars.
• Do not mount equipment on the headliner within 200 mm (8 in) of the side edges.
