A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment.
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 indi-
cates an electrical problem. Avoid
using the system involved and immedi-
ately consult a HYUNDAI authorised
repairer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse 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
system.
CAUTION
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-
minium foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

Maintenance
Instrument panel fuse replace-
ment
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 ofthe fuse panel cover to locate the
suspected fuse location. 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 pro-
vided in the instrument panel fuse
panels (or in the engine compart-
ment 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 rec-
ommend that you consult 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 you may not
need for operating the vehicle, such
as the cigarette lighter fuse.
If the headlamps or other electrical
components do not work and the
fuses are undamaged, check the
fuse panel in the engine compart-
ment. If a fuse is blown, it must be
replaced with the same rating.

If you move the switch to the OFF
position, some items such as the
audio system and digital clock must
be reset and the smart key may not
work properly.

If the fuse switch is OFF, “Turn on
FUSE SWITCH” message will appear.
Always place the fuse switch inthe ON position whilst driving
the vehicle.
Do not move the transportation fuse switch repeatedly. The fuse
switch may be damaged.

4. Check the removed fuse; replace itif 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 fits loosely, we rec-
ommend that you consult a
HYUNDAI authorised repairer.
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 con-
tact.Main fuse (Plug-in hybrid vehicle)
The electronic system may not func-
tion correctly even when the fuses
located in the engine compartment
and instrument panel are not discon-
nected. In such case, the cause of the
problem may be disconnection of the
main fuse (BFT type), which is located
inside the positive battery terminal (+)
cap. Since the main fuse is designed
more intricately than other parts, we
recommend you visit the nearest
HYUNDAI authorised repairer.
Information
After inspection always securely
install the battery cap. If it is not
securely latched, electrical failure may
occur from water contact.
Multi fuse
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 pic- ture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.
Information
If the multi fuse is blown, we recom-
mend that you consult a HYUNDAI
authorised repairer.
