Damaged Vehicle
Before attempting to rescue occupants from a
damaged FCX or to move a damaged
vehicle, it’s important to prevent electric
current from flowing through the high
voltage cables and to prevent hydrogen
leakage.
You have three ways to do this, ranging from
the best method to the least desirable.
Best method for preventing current flow
and hydrogen leakage:
Turn the key switch off, remove the key, and
turn off the manual hydrogen shut-off valve
(see page 11).
Second-best method for preventing current
flow and hydrogen leakage:
Disconnect the 12-volt battery negative cable
and the negative DC-to-DC converter cable,
then turn off the manual hydrogen shut-off
valve (see page 12).
Least-desirable method for preventing
current flow and hydrogen leakage:
Turn off the capacitor module main switch,
then turn off the manual hydrogen shut-off
valve (see page 14).
If you cannot perform any of these
methods, use extreme care.
• Do not cut into any high-voltage
components or high-voltage cables.
• Do not touch the cables, because they may
be “hot.”
