A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment
near the battery.
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
HYUNDAI dealer.
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.

2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside of the fuse panel cover to locate the
suspected fuse location.
ODN8089016ODN8089016
5. Pull the suspected fuse straight out. Use the removal tool provided in the
engine compartment fuse panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment fuse panel).
7. 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.
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 undamaged, check the fuse panel
in the engine compartment. If a fuse is
blown, it must be replaced with the same
rating.
