In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not
need for operating the vehicle.
If the headlamps or other electrical
components do not work and the
fuses are OK, check the fuse panel
in the fuel cell power module com-
partment. If a fuse is blown, it must
be replaced with the same rating.Fuel Cell Power Module
