High Voltage Battery System
OAEPHQ016040L
Never touch orange colored or
high voltage labeled compo-
nents, including wires, cables,
and connections. When the insu-
lators or covers are damaged or
removed, severe injury or death
from electrocution may occur.
WARNING
While replacing the fuses in the
engine compartment, never
touch the HPCU. The HPCU car-
ries high voltage. Touching the
HPCU may result in electrocu-
tion, serious injury, or death.

SAFETY PRECAUTIONS FOR HYBRID SYSTEM (CONT.)
(Continued)
•Do not drop water or liquid on
to HPCU, HSG, motor and
fuses. The hybrid system com-
ponents are covered. If you
drop water or liquid on to
hybrid system components, it
may result in electric shock.
This hybrid vehicle uses the
hybrid battery system inverter
and converter to generate high
voltage. High voltage in the
hybrid battery system is very
dangerous and may cause
severe burns and electric
shock. This may result in seri-
ous injury or death.
•For your safety, never touch,
replace, disassemble or remove
the hybrid battery system
including components, cables
and connectors. Severe burns
or electric shock may result in
serious injury or death when
you fail to follow this warning.
•When the hybrid battery sys-
tem operates, the hybrid bat-
tery system can be hot. Always
be careful because burns or
electric shock may be caused
by high voltage.

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.
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 an authorized HYUNDAI
dealer.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-
minum 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 of
the 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 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, 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.

Maintenance
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 fits loosely, consult
an authorized HYUNDAI dealer.
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 dealer.
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, consult an
authorized HYUNDAI dealer.
