FUSES
A vehicle’s electrical system is protected
from electrical overload damage by fuses.
This vehicle has 2 fuse panels, one locat-
ed 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 appro-
priate 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.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 immediately
consult an authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,and multi fuse for higher amperage ratings.
✽ ✽ NOTICE
The actual fuse/relay panel label may
differ from equipped items.
WARNING - Fuse
replacement
Never replace a fuse with anything
but another fuse of the same rat-
ing.
A higher capacity fuse could cause damage and possibly a fire.
Never install a wire or aluminum foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to remove fusesbecause it may cause a short circuit and damage the system.
CAUTION
When replacing a blown fuse or relay with a new one, make surethe new fuse or relay fits tightly into the clips. The incomplete fas-tening fuse or relay may cause the vehicle wiring and electric sys-tems damage and a possible fire.
Do not remove fuses, relays and terminals fastened with bolts ornuts. The fuses, relays and termi-nals may be fastened incomplete- ly, and it may cause a possiblefire. If fuses, relays and terminals fastened with bolts or nuts areblown, consult with an authorized HYUNDAI dealer.
Do not input any other objects except fuses or relays intofuse/relay terminals such as a driv-er or wiring. It may cause contact failure and system malfunction.

Instrument panel fuse replace-
ment
1. Turn the engine start/stop button and
all other switches 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, consult an authorized
HYUNDAI dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you maynot need for operating the vehicle, suchas the cigarette lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse panel in the engine
compartment. If a fuse is blown, it must
be replaced.
Memory fuse
Your vehicle is equipped with a memory
fuse to prevent 12V battery discharge if
your vehicle is parked without being
operated for prolonged periods. Use the
following procedures before parking the
vehicle for prolonged periods.
1. Turn off the engine.
2. Turn off the headlights and tail lights.
3. Open the driver’s side panel cover and pull up the memory fuse.

THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING
In the hybrid system, the hybrid bat-
tery uses high voltage to operate the
motor and other components. This
high voltage hybrid battery system
can be very dangerous. Never touch
the hybrid system. If you touch the
hybrid battery system, serious
injury or death may occur.
WARNING
Never touch orange or high voltage
labeled components including
wires, cables, and connections. If
the insulators or covers are dam-
aged or removed, severe injury or
death from electrocution may occur.
WARNING
When replacing the fuses in the
engine compartment, never touch
the HPCU. The HPCU carries high
voltage. Touching the HPCU could
result in electrocution, serious
injury, or death.

OYFH021002N
WARNING
• Do not disassemble the high volt-age motor connector. The high
voltage motor connector may con-
tain residual high voltage. Coming
in contact with high voltage may
result in death or serious injury.
Your vehicle's hybrid system should only be inspected or
repaired by an authorized
Hyundai dealer.

Safety plug
This safety plug (1) located in the rear
trunk as shown should always be pulled
out to disconnect and turn off the hybrid
system.
IMPORTANT: Wait 5 minutes after this
lever is disconnected to work on the
car to assure all remaining charge in
the system has dissipated.
The special features of hybrid
vehicle.
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may hear a
sound from the hybrid battery system
behind the rear seat. If you apply the
accelerator pedal rapidly, you may hear
an unconventional sound. When you
apply the brake pedal, you may hear a
sound from the regenerative brake sys-
tem. When the hybrid system is turned
off or on, you may hear a sound in the
engine compartment. If you depress the
brake pedal repeatedly when the hybrid
system is turned on, you may hear a
sound in the engine compartment. None
of these sounds indicate a problem.
These are normal characteristics of
hybrid vehicles.
If any of following occur, it's a normal
condition if you hear a motor sound in the
engine compartment:
- After turning off the hybrid system, thebrake pedal is released.
- When the hybrid system is turned off, the brake pedal is applied.
- When the driver door is opened.
THE COMPONENTS OF HYBRID VEHICLE (CONT.)
WARNING
This hybrid vehicle uses the hybrid
battery system inverter and con-
verter to generate high voltage.
High voltage in the hybrid battery
system is very dangerous and can
cause severe burns and electric
shock. This may result in serious
injury or death.
For your safety, never touch, replace, dismantle or remove the
hybrid battery system including
components, cables and connec-
tors. Severe burns or electric
shock may result in serious
injury or death if you do not fol-
low this warning.
When the hybrid battery system operates, the hybrid battery sys-
tem can be hot. Always be careful
because burns or electric shock
may be caused by high voltage.
Do not drop water or liquid on to HPCU, HSG, Motor and fuses. The
hybrid system components are
covered. If you drop water or liq-
uid on to hybrid system compo-
nents, it may result in electric
shock.
DANGER
The safety plug is attached to high
the voltage hybrid battery system.
Touching safety plug may result in
death or serious injury. Service per-
sonnel should follow procedure in
the service manual.
