heating or air conditioning (Plug-in
hybrid vehicle)OAEPHQ049841L
This message is displayed when the
vehicle maintains the HEV mode to allow
heating or air conditioning. The mode
does not change when the driver presses
the [HEV] button to switch from the HEV
mode to EV mode while the heating and
cooling system is on and the coolant
temperature is below (70°C) and outdoor
temperature is below -15°C.

battery is too low or high. This warning
message is to protect the battery and the
hybrid system.
Switching to Hybrid mode to
lubricate engine (Plug-in hybrid
vehicle)
OAEPHQ049838L
This message is displayed when the
vehicle is automatically switched to the
HEV mode to lubricate engine while the
ignition switch is in the ON position. Maintaining Hybrid mode to protect
engine (Plug-in hybrid vehicle)
OAEPHQ049839L
This message is displayed when
the [HEV] button is pressed but it is
impossible to switch from the HEV mode
to EV mode due to engine lubrication.
Exit SPORT mode to switch to EV
(Plug-in hybrid vehicle)
OAEPHQ049840L
This message is displayed when [HEV]
button is pressed but it is impossible to
switch from the HEV mode to EV mode
because the SPORT mode is engaged.

SAFETY PRECAUTIONS FOR HYBRID SYSTEM
Hybrid Vehicle Components
High voltage battery system
„HPCU (Hybrid Power Control Unit) *1

„High voltage battery system *2
OTMHQ010014
„High voltage battery system *3 (Plug-in hybrid vehicle)
OTMPHQ010019L
*1 : Located in the engine compartment
*2 : Located under the floor
*3 : Located First Row Seat Outdoor
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.

[ Be careful when loading flammable liquid in the passenger compartment. It could cause
operational and safety degradation if
the liquid leaks and flows in the high
voltage battery.

WARNING

[ Do not disassemble the high voltage
motor connector. The high voltage
motor connector may contain
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.
WARNING

[ Do not disassemble or assemble
the high voltage battery system.
Doing so may result in electric shock,
causing death or serious injury.

[ If you disassemble or assemble
hybrid system components
improperly, it may damage the
performance and reliability of your
vehicle.

[ If electrolyte comes in contact
with your body, clothes or eyes,
immediately flush with a large
quantity of fresh tap water. Have
your eyes examined by a doctor as soon as possible.
WARNING
Never assemble or disassemble the
high voltage battery system.
[ If you assemble or disassemble the
high voltage battery system, the
durability and performance of the
vehicle may be damaged.

[ When you want to check the high
voltage battery system, have the
vehicle inspected by an authorized
HYUNDAI dealer.

[ Do not touch the high voltage
battery and high voltage cable
connected to motor (orange color).
Severe burns and electric shock may
occur. For your safety, do not touch
the cover of electronic components
and electronic cable. Do not remove
the cover of electronic components
and electronic cable. In particular,
never touch the high voltage battery
system when the hybrid system in
operation. It may result in death or
serious injury.
WARNING

[ Never use the package modules
(high voltage battery, inverter and
converter) for any other purpose.

[ Do not use an unauthorized battery
charger to charge the high voltage
battery. Doing so may result in death
or serious injury.

[ Never locate the high voltage system
near or in a fire.

[ Never drill into or strike the package
module. Otherwise, it may be
damaged. An electric shock may
occur, resulting in serious injury or
death.
