Your HYUNDAI should not be modified in any way. Such modifications may
adversely affect the performance, safety or durability of your HYUNDAI
and may, in addition, violate conditions of the limited warranties covering
the vehicle. Certain modifications may also be in violation of regulations
established by the U.S. Department of Transportation and other federal or state
agencies.
Your vehicle is equipped with electronic fuel injection and other electronic
components. It is possible for an improperly installed/adjusted two-way radio
or cellular telephone to adversely affect electronic systems. For this reason,
we recommend that you carefully follow the radio manufacturer’s instructions
or consult your HYUNDAI dealer for precautionary measures or special
instructions if you choose to install one of these devices.

engine components, never add any fuel
system cleaning agents to the fuel tank
other than what has been specified.
Consult an authorized HYUNDAI dealer
for additional information.
WARNING

automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.

VEHICLE DATA COLLECTION
AND EVENT DATA
RECORDERS
This vehicle is equipped with an event
data recorder (EDR). The main purpose
of an EDR is to record, in certain crash
or near crash-like situations, such as
an air bag deployment or hitting a
road obstacle, data that will assist in
understanding how a vehicle’s systems
performed. The EDR is designed to
record data related to vehicle dynamics
and safety systems for a short period of
time, typically 30 seconds or less. The
EDR in this vehicle is designed to record
such data as:
• How various systems in your vehicle
were operating;
• Whether or not the driver and
passenger safety belts were buckled/
fastened;
• How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data is recorded by your vehicle
only if a non-trivial crash situation
occurs; no data are recorded by the
EDR under normal driving conditions
and no personal data (e.g., name,
gender, age, and crash location) are
recorded. However, other parties, such
as law enforcement, could combine the
EDR data with the type of personally
identifying data routinely acquired
during a crash investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such as
law enforcement, that have the special
equipment, can read the information if
they have access to the vehicle or the
EDR.
WARNING
CALIFORNIA PROPOSITION 65
WARNING

emitted from them are known to the
State of California to cause cancer and
birth defects or reproductive harm.
These include:
• Gasoline and its vapors
• Engine exhaust
• Used engine oil
• Interior passenger compartment
components and materials
• Component parts which are subject
to heat and wear
In addition, battery posts, terminals and
related accessories contain lead, lead
compounds and other chemicals known
to the State of California to cause

When the hybrid system is turned ON,
the gasoline engine may run or may not.
In this situation, you may feel a vibration.
This does not indicate a malfunction.
When the “
” indicator illuminates, the hybrid system is ready to begin driving.
Even if the engine is off, you can operate
the vehicle as long as the “
” indicator is illuminated.
NOTICE
The hybrid system contains many
electronic components. High voltage
components, such as cables and other
parts, may emit electromagnetic waves.
Even when the electromagnetic cover
blocks electromagnetic emissions,
electromagnetic waves may have an
effect on electronic devices. When your
vehicle is not used for a long period of
time, the hybrid system will discharge.
You need to drive the vehicle several
times a month. We recommend driving
at least for 1 hour or 10 miles. When the
hybrid battery is discharged, or when it
is impossible to jump start the vehicle,
we recommend that you contact your
authorized HYUNDAI dealer.
WARNING
• When you start the hybrid system
with the shift button in P (Parking),
the “
” indicator illuminates on the instrument cluster. The driver
can drive the vehicle, even when the
gasoline engine is off.
• When you leave the vehicle, you
should turn OFF the hybrid system
or locate the shift button in P (Park).
When you depress the accelerator
pedal by mistake, or when the shift
button is not in P (Park), the vehicle
will abruptly move, possibly resulting
in serious injury or death.
Virtual Engine Sound System (VESS)
The Virtual Engine Sound System
generates engine sound for pedestrians
to hear vehicle sound because there is
limited sound while motor power is used.
• If the gear shifts from P (Parking) after
start-up, the VESS sound is output.
• When the gear is shifted to R
(Reverse), an additional warning
sound will be heard.
What does regenerative braking do?
It uses an electric motor when
decelerating and when braking. It
transforms kinetic energy to electrical
energy in order to charge the high
voltage battery.
Battery
• The vehicle is composed of a high
voltage battery that drives the motor
and air conditioner, and an integrated
12V lithium ion polymer battery with
the HEV battery that drives the lamps,
wipers, and audio system.
• The integrated 12V battery is
automatically charged when the
vehicle is in the ready (
) mode.

Warning and Indicator Lights
Ready indicator
This indicator illuminates:
When the vehicle is ready to be driven.
-ON : Normal driving is possible.
-OFF : Normal driving is not possible,
or a problem has occurred.
-Blinking : Emergency driving.
When the ready indicator goes OFF
or blinks, there is a problem with the
system. If this occurs, we recommend
that you have your vehicle inspected by
an authorized HYUNDAI dealer.
EV mode indicator
This indicator illuminates:
When the vehicle is driven by the electric
motor.
Service warning light
This warning light illuminates:
• When you set the ignition switch or
the Engine Start/Stop button to the
ON position.
-The service warning light illuminates
for approximately 3 seconds and
then turns off when all checks have
been performed.
• When there is a problem with the
hybrid vehicle control system or
hardware.
When the warning light illuminates
while driving, or does not go OFF after
starting the vehicle, we recommend that
you have the vehicle inspected by an
authorized HYUNDAI dealer.
Regenerative brake warning
light
(yellow)
This warning light illuminates:
When the regenerative brake does not
operate and the brake does not perform
well. This causes the Brake Warning
light (red) and Regenerative Brake
Warning Light (yellow) to illuminate
simultaneously.
If this occurs, drive safely and have
your vehicle inspected by an authorized
HYUNDAI dealer. The operation of the
brake pedal may be more difficult than
normal and the braking distance may
increase.

SAFETY PRECAUTIONS FOR HYBRID SYSTEM
Hybrid Vehicle Components
High voltage battery system
„„HPCU (Hybrid Power Control Unit) *1
OCN7HQ010006
„„High voltage battery system *2
OAEQ046019
*1 : Located in the engine compartment
*2 : Located under the rear seats
WARNING
Never touch orange colored or high
voltage labeled components, including
wires, cables, and connections. When
the insulators 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 carries high voltage.
Touching the HPCU may result in
electrocution, serious injury, or death.
WARNING
In the hybrid system, the hybrid battery
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. When
you touch the hybrid battery system,
serious injury or death may occur.
CAUTION
• 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 luggage
compartment. Such an attempt
may distort the high voltage battery
case, causing a safety problem or
degrading the performance.
• Be careful when loading flammable
liquid in the luggage compartment.
It could cause operational and safety
degradation if the liquid leaks and
flows in the high voltage battery.
