•
(MANDATORY)
Secure the vehicle: Ensure the vehicle transmission gear selector is in the PARK position. Check that the vehicle ready
light is off to verify the High Voltage system is disconnected. If the vehicle ready light is on, press the Start button to turn off the ignition.
PLEASE NOTE: The vehicle high voltage system could still be energized even if the ready light is not on. In accessory mode,
the ready light is not present but the high voltage system is energized under normal operation.
•
(MANDATORY)
First, turn off the charge unit. Then, attempt to remove the High Voltage Charge Cord if connected to the vehicle. If the
plug will not release please refer to High Voltage. Charge Cord Lock Manual Release, in Section 3 of this guide.
•
(MANDATORY)
Disconnect the 12 volts battery terminals to isolate the HV system. For additional information, refer to High Voltage
System Depower procedures in this manual.
•
(MANDATORY)
If the vehicle is on fire, use a Class ABC powder-type extinguisher to contain and smother the flames. If water is being
used, LARGE amounts of water is required to extinguish the flames. A fire-hydrant or dedicated fire hose can supply the needed amount.
Water can cause some degree of arcing/shorting across the cell and/or battery terminals; it can also react with the electrolyte from the
cells to generate additional combustible gas and other byproducts such as hydrofluoric acid. However, the cooling and smothering effects
of flushing the affected article with large amounts of water and/or other fire suppression material is still beneficial for minimizing the
severity of the event.
•
(MANDATORY)
If the vehicle has any exposed cables, wear High Voltage rubber gloves and other appropriate PPE. Do not touch any
broken or damaged High Voltage orange cables. Treat severed cables as if they contain High Voltage.
•
(MANDATORY)
If the vehicle is submerged in water, varying degrees of arcing/shorting within the battery will take place. Do not touch
any High Voltage components or orange cables while removing the occupant(s). Do not remove the vehicle until you are sure the High
Voltage battery is completely discharged. A submerged High Voltage battery may produce a fizzing or bubbling reaction to the water. If
fizzing or bubbling is observed, the High Voltage battery will be discharged when the fizzing or bubbling has completely stopped. The
battery should still be treated as if it is not discharged.
•
If necessary, apply the parking brake and/or block the wheels to prevent vehicle movement.
•
The vehicle has an electric parking brake. You operate it with a switch instead of a lever. The switch is on the center console or to the left
hand side of the steering wheel, on the lower part of the instrument panel.
High Voltage System - Do Not Cut Zones
•
If possible, depower the High Voltage system before attempting any removal procedure. Always assume the High Voltage cabling and
components are powered up.
•
If occupant removal is necessary, always use caution when cutting near the vehicle High Voltage system components. Do not cut any of
the High Voltage under vehicle or under hood cabling (all High Voltage cabling is orange). High voltage cabling runs underneath the
vehicle, from the High Voltage batteries under the left hand side of the vehicle to the underhood compartments. The vehicle charge port
is located on the left front fender. Refer to the diagram below for the no cut zones.
See Section 1 for illustrations.
If The High Voltage Battery Case Has Been Ruptured
Just like any other battery, hose down the area with
LARGE
amounts of water.
Moving Damaged Vehicles - Tow Truck Drivers
NOTICE:
Do not attempt to pull / tow vehicle with wheels on the ground as this may cause the vehicle to generate electricity and can cause
potential damage.
•
Disconnect the 12 volts battery terminals to isolate the HV system. For additional information, refer to High Voltage System Depower
procedures in this manual.
•
Rather than attempt to discharge a High Voltage battery, an emergency responder, tow truck operator, or storage facility manager should
contact experts at the vehicle manufacturer.
•
Operators of tow trucks and vehicle storage facilities should make sure the damaged vehicle is kept in an open area instead of inside a
garage or other enclosed building.
Follow the guidelines in the Wrecker Towing Guide:
•
If you detect leaking fluids, sparks, smoke, flames, increased temperature, gurgling, popping or hissing noises from the High Voltage
battery compartment, ventilate the area and call 911.
•
Be alert. There is potential for delayed fire with damaged lithium-ion batteries.
•
Call an authorized Ford dealer or vehicle manufacturer representative, if necessary, to determine the additional steps to take to safely
recover or transport the vehicle.
•
Always approach the vehicle from the sides to stay out of potential travel path. It may be difficult to determine if the vehicle is running due
to lack of engine noise.
•
Place vehicle into park, set the parking brake, turn off the vehicle, activate the hazard lights, and remove the key fobs to a distance at
least 16 feet from the vehicle until loading the vehicle for transport.
•
Refer to vehicle manual/recovery guide to locate proper attachment/connection points and transport method.
