■ HPCU (Hybrid Power Control Unit)
■ High Voltage Battery System 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.
WARNING
In the hybrid system, the hybrid
battery uses high voltage tooperate the motor and other
components. This high voltage
hybrid battery system can be
very dangerous. Never touch the
hybrid system. When you touch
the hybrid battery system, seri-
ous injury or death may occur.
WARNING
Do not pile up any items in an
area behind the high voltage
battery. In a crash, the battery
may become unstable, or its
performance may degrade.
Do not apply strong force nor
pile up any items above the
trunk. Such an attempt may
distort the high voltage battery
case, causing a safety problem
or degrading the performance.

Information
Gradual capacity reduction of the
high voltage battery.
The high voltage Battery capacity
gradually reduces with time and use.
This is natural characteristic of the
high voltage batteries. The extent at
which capacity is reduced changes
drastically depending on the environ-
ment(ambient temperature, etc.) and
usage conditions such as how the vehi-
cle is driven and how the high voltage
battery is charged. Reduction of the
high voltage battery capacity is not
covered under warranty.
Safety Plug
i
OLFHQ014005K
Never touch the safety plug. The
safety plug is attached to high
voltage hybrid battery system.
Touching the safety plug will
result in death or serious injury.
Service personnel should follow
procedures in service manual.
DANGER
(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 compone nts, 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
serious 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.

Low Tire Pressure
This warning message is displayed if
the tire pressure is low. The corre-
sponding tire on the vehicle will beilluminated.
For more information, refer to "Tire Pressure Monitoring System
(TPMS)" in chapter 6.
Turn on FUSE SWITCH
This warning message is displayed if
the fuse switch in the instrument
panel fuse, under the steering wheel
is OFF.
If this message is displayed, turn the
fuse switch on.
For more information, refer to
"Fuses" in chapter 7.
Align steering wheel (if equipped)
This warning message is displayed
when the steering wheel is turned by
90 degrees or wider, either to the left
or to the right, while running the
engine.
In order to align the steering wheel,
turn the wheel in the direction shown
while the engine is running to
straighten the steering wheel.
Steering wheel aligning is com-pleted (if equipped)
If the steering wheel aligning is com-
pleted after "Align steering wheel"
warning message is displayed, this
message is displayed for 2 seconds.
Low Washer Fluid
This warning message is displayed
in the service reminder mode, when
the washer fluid in the reservoir is
nearly empty.
If this warning message is displayed,
have the washer fluid reservoirrefilled.
Low Fuel
This warning message is displayed ifthe fuel tank is almost out of fuel.
When this message is displayed, the
vehicle range is approximately 48 km(30 miles).
When this message is displayed, the
low fuel level warning light in the
instrument cluster will come on.
It is recommended to look for the nearest fueling station and refuel as
soon as possible.

FFUU SSEE SS
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 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
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer. Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.i

Normal Blown
Normal Blown
OLF074075 NEVER replace a fuse with any-
thing but another fuse of thesame 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.
WARNING

■ Multi fuse

Instrument panel fuse replace- ment
1. Turn the hybrid system 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 fusespanel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are
provided in the instrument panelfuse panels (or in the engine com-
partment 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, consult
an authorized HYUNDAI dealer.

Maintenance
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage thesystem.

Maintenance
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 OK, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced with the
same rating.Fuse switch
Always, place the fuse switch to theON position.
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.Information
If the fuse switch is OFF, the above
message will appear.
Always place the fuse switch in the ON position while driving the
vehicle.
Do not move the fuse switch repeatedly. The fuse switch may
be damaged.
