NormalBlown
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.
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 we
recommend that all inspect a HYUNDAI
authorised repairer.

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 aluminium
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.

1. Turn the vehicle off.
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 broken fuse location.
OBC3N091018AU
5. Pull the suspected fuse straight out.
Use the removal tool provided in the
engine compartment fuses 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, we recommend
that you consult with a HYUNDAI
authorised repairer.
In an emergency, if you do not have a
spare fuse, use a fuse of the same rating
from a circuit such as the cigarette
lighter fuse.
If the headlights 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.

Engine compartment panel fuse
replacement
OBC3N090020
1. Turn the vehicle off.
2. Turn all other switches OFF.
3. Remove the fuse panel cover by
pressing the tab and pulling up.
4. Check the removed fuse; replace it
if it is blown. To remove or insert the
fuse, use the fuse puller in the engine
compartment fuse panel.
5. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips. If it does not fit tightly,
we recommend that you consult a
HYUNDAI authorised repairer.
NOTICE
After checking the fuse panel in the
engine compartment, securely
install the fuse panel cover. You may
hear a clicking sound if the cover is
securely latched. If it is not securely
latched, electrical failure may occur
from water contact.

OBC3N091019AU
If the multi fuse is blown, it must be
removed as follows:
1. Turn the vehicle off.
2. Disconnect the negative battery cable.
3. Remove the fuse panel cover by
pressing the tab and pulling it up.
4. Remove the nuts shown in the picture
above.
5. Replace the fuse with a new one of
the same rating.
6. Reinstall in the reverse order of
removal.
If the multi fuse is blown, we
recommend that you consult with a
HYUNDAI authorised repairer.
