D : Midi type
O: Normal, X: Blown
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 5 fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment.
If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved and
immediately consult an authorized
retailer of Genesis Branded products.
WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.

[A higher capacity fuse could cause
damage and possibly cause a fire.

[Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.
