Maintenance
A vehicle's electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 4 fuse panels, one
located in the driver's side panel bol-
ster, another in the engine compart-
ment, and two others in the trunk
compartment.
If any of your vehicle's lights, acces-
sories, 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 rat-
ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized retailer
of Genesis Branded products.
Information
Four kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, multi fuse and fusible link
for higher amperage ratings.
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.

NEVER replace a fuse with any-
thing 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 alu-
minum foil instead of the
proper fuse - even as a tempo-
rary repair. It may cause
extensive wiring damage and
possibly a fire.
