High Voltage Electrical Disconnect Features
WARNING:
HYBRID VEHICLES DAMAGED BY A CRASH MAY HAVE COMPROMISED HIGH VOLTAGE SAFETY SYSTEMS AND PRESENT A
POTENTIAL HIGH VOLTAGE ELECTRICAL SHOCK HAZARD. EXERCISE CAUTION AND WEAR APPROPRIATE PERSONAL
PROTECTIVE EQUIPMENT (PPE) INCLUDING HIGH VOLTAGE SAFETY GLOVES AND BOOTS. REMOVE ALL METALLIC JEWELRY,
INCLUDING WATCHES AND RINGS. ISOLATE THE HIGH VOLTAGE SYSTEM AS DIRECTED BY THE FORD EMERGENCY RESPONSE
GUIDE FOR THE VEHICLE. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SERIOUS PERSONAL INJURY OR
DEATH.
The following features have been incorporated into these vehicles to allow for either simple or automatic shut-off of the High Voltage electrical
systems.
• High voltage fuse — In the event of a High Voltage short circuit, the High Voltage fuse opens, isolating the High Voltage battery from the
circuit.
• Ignition in the OFF Position PHEV Vehicles — Any time the ignition is in the off position AND charge cable is not connected to the vehicle
charge port, the High Voltage system is isolated to the battery pack.
• If the ignition in the OFF Position and the 12 volt battery cables are disconnected, the High Voltage is isolated to the battery pack.
• In the event of a moderate to severe crash, the vehicle shutoff feature stops the flow of fuel to the engine, and deactivates the high
voltage system. PLEASE NOTE not every crash will cause the vehicle to shutoff or High Voltage system deactivation.
High Voltage Battery Packs
WARNING:
HYBRID VEHICLES DAMAGED BY A CRASH MAY HAVE COMPROMISED HIGH VOLTAGE SAFETY SYSTEMS AND PRESENT A
POTENTIAL HIGH VOLTAGE ELECTRICAL SHOCK HAZARD. EXERCISE CAUTION AND WEAR APPROPRIATE PERSONAL
PROTECTIVE EQUIPMENT (PPE) INCLUDING HIGH VOLTAGE SAFETY GLOVES AND BOOTS. REMOVE ALL METALLIC JEWELRY,
INCLUDING WATCHES AND RINGS. ISOLATE THE HIGH VOLTAGE SYSTEM AS DIRECTED BY THE FORD EMERGENCY RESPONSE
GUIDE FOR THE VEHICLE. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SERIOUS PERSONAL INJURY OR
DEATH.
WARNING:
FIRES IN CRASH-DAMAGED ELECTRIC VEHICLES MAY EMIT TOXIC OR COMBUSTIBLE GASSES. SMALL AMOUNTS OF EYE, SKIN
OR LUNG IRRITANTS MAY BE PRESENT. WEAR PERSONAL PROTECTIVE EQUIPMENT (PPE) AND SELF-CONTAINED BREATHING
APPARATUS WHEN WORKING IN CLOSE PROXIMITY OR IN A CONFINED AREA, SUCH AS A TUNNEL OR GARAGE. VENTILATE
THE VEHICLE INTERIOR BY OPENING VEHICLE WINDOWS OR DOORS. VENTILATE THE WORKING AREA. FAILURE TO FOLLOW
THIS INSTRUCTION MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
WARNING:
DEPOWERING THE HIGH VOLTAGE SYSTEM DOES NOT DISSIPATE VOLTAGE INSIDE THE BATTERY, THE BATTERY PACK
REMAINS LIVE AND DANGEROUS. CONTACT WITH THE HIGH VOLTAGE BATTERY PACK INTERNALS MAY RESULT IN SERIOUS
PERSONAL INJURY OR DEATH.
Observe the following precautions when working on or around High Voltage batteries:
• Do not cut the High Voltage battery case. Do not penetrate the batteries or case in any way.
The High Voltage battery pack is located under the vehicle.
•
• The total voltage of the vehicle HV battery pack may be up to approximately 450 volts DC.
• The battery case is water resistant.
• The battery cells contain liquid electrolyte absorbed in a porous special polymeric film. The electrolyte will not leak from the battery under
most conditions. However, if the battery is crushed, it is possible for a small amount of electrolyte to leak.
• If possible, isolate and avoid contact with any electric vehicle components. If contact with the High Voltage system cannot be avoided,
Personal Protective Equipment (PPE) such as a splash shield or safety goggles, gloves (butyl), an apron or overcoat, and rubber boots
are required when handling damaged batteries. Exposure to electrolyte could cause skin and/or eye irritation/burns. If exposed, rinse with
large amounts of water for 10-15 minutes.
