FUSES
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 near the battery.
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. Before replacing a blown fuse,
turn the engine and all switches off,
and then disconnect the negative bat-
tery cable. 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 immedi-
ately consult a HYUNDAI authorised
repairer.Information
Four kinds of fuses are used : blade type
for lower amperage rating, cartridge
type/Multi fuse/Battery fuse terminal for
higher amperage ratings.

Maintenance
Inner panel fuse replacement
1. Turn the engine and all otherswitches off.
2. Open the fuse panel cover. 3. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuse
panel.
4. Check the removed fuse; replace it if it is blown.
5. 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 a HYUNDAI authorised
repairer.
Information
If you do not have a spare, use a fuse
of the same rating from a circuit you
may not need for operating the vehi-
cle, such as the cigar lighter fuse.
If the headlights or other electrical
components do not work and the
fuses are OK, check the fuse block in
the engine compartment. If a fuse is
blown, it must be replaced with the
same rating.

The main fuse is heavily connected
to many other parts. In this case, we
recommend you to contact a
HYUNDAI authorised repairer.

If the multi fuse is blown, it must be
removed as follows:
1. Disconnect the negative batterycable.
2. Remove the nuts shown in the pic- ture above.
3. Replace the fuse with a new one of the same rating.
4. Reinstall in the reverse order of removal.
