FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine 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.
If the electrical system does not work,
first check the driver’s side fuse panel.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,
and multi fuse for higher amperage rat-
ings.
OLM079051N
WARNING - Fuse replace-
ment
Never replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly a
fire.
Never install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove fuses
because it may cause a short circuit
and damage the system.

5. Push in a new fuse of the same rating,
and make sure it fits tightly in the clips.
If it fits loosely, consult an authorized
HYUNDAI dealer.
If you do not have a spare, use a fuse of
the same rating from a circuit you may
not need for operating the vehicle, such
as the cigarette lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse panel in the engine
compartment. If a fuse is blown, it must
be replaced.
