SAFETY PRECAUTIONS FOR HYBRID SYSTEM
Hybrid Vehicle Components
High voltage battery system
„HPCU (Hybrid Power Control Unit) *1
OTMPHQ011017N
„High voltage battery system *2
OTMHQ010014
*1 :
Located in the engine compartment
*2 : Located under the floor
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.

Foreword / Hybrid System Overview1-22
NOTICE

[ When the vehicle is paint baked, do
not bake over 30 minutes in 158°F
(70°C) or 20 minutes in 176°F (80°C)
degree.

[ Do not wash the engine
compartment, using water. Water
may cause an electric shock and
damage the electronic components.
WARNING
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 system
operates, the hybrid battery system
can be hot. Always be careful
because burns or electric shock may
be caused by high voltage.

[ Do not spill liquid on the HPCU, HSG,
motor and fuses. If the hybrid system
components come in contact with
liquid, it may result in electric shock.
Service Interlock Connector
OTMHQ010016
In case of emergency, cut the service
interlock connector cable to disable the
high voltage of the battery.
WARNING
Never disconnect the service interlock
connector or cut the wire except in an
emergency situation.
Serious problems may occur, such as
the vehicle will not start.
WARNING
Regardless of the disabling procedure
you use, Always assume that all high
voltage components are energized!
Cutting, crushing, or touching high
voltage components can result in
serious injury or death.

Instrument Cluster4-24
Press START button with key (if
equipped)
This message is displayed if you press
the Engine Start/Stop button while the
warning message “Key not detected” is
displayed.
At this time, the immobilizer indicator
light blinks.
Check BRAKE SWITCH fuse (if
equipped)
This message is displayed if the brake
switch fuse is disconnected.
You need to replace the fuse with a new
one before starting the engine.
If that is not possible, you can start the
engine by pressing the Engine Start/
Stop button for 10 seconds in the ACC
position.
12V battery discharging due to
additional electrical devices (if
equipped)
This message is displayed if the 12V
battery voltage is weak due to any
non-factory electrical accessories (ex.
dashboard camera) while parking. Be
careful that the battery is not discharged.
If the message appears after removing
the non-factory electrical accessories,
you have the vehicle inspected by an
authorized HYUNDAI dealer.
Door, Hood, Liftgate open indicator
OTM040032
This warning is displayed if any door or
the hood or the liftgate is left open. The
warning will indicate which door is open
in the display.
CAUTION
Before driving the vehicle, you should
confirm that the door/hood/liftgate
are fully closed. Also, check there is no
door/hood/liftgate open warning light
or message displayed on the instrument
cluster.

Convenience Features5-62
Power window lock button
OTM050092L
The driver can disable the power window
switches on the rear passenger doors by
pressing the power window lock button.
When the power window lock button is
pressed:

[ The driver’s master control can
operate all the power windows.

[ The front passenger’s control can
operate the front passenger’s power
window.

[ The rear passenger’s control cannot
operate the rear passengers’ power
window.

à If the power window lock button is
operated (indicator turns on), rear
passenger cannot open the rear door
(if equipped with the Electronic Child
Safety Lock System).
For more details, refer to “Electronic
Child Safety Lock System” system in this
chapter.
WARNING
Do not allow children to play with the
power windows. Keep the driver’s
door power window lock button in the
LOCK position. Serious injury or death
can result from unintentional window
operation by a child.
NOTICE

[ To prevent possible damage to the
power window system, do not open
or close two windows or more at the
same time. This will also ensure the
longevity of the fuse.

[ Never try to operate the main
switch on the driver’s door and the
individual door window switch in
opposite directions at the same time.
If this is done, the window will stop
and cannot be opened or closed.

Convenience Features5-66
NOTICE

[ Do not continue to push the sunroof
switch after the sunroof is fully
opened, closed, or tilted. Damage to
the sunroof motor could occur.

[ Continuous operations such as slide
open/close, tilt open/close, etc. may
cause the motor or sunroof system to
malfunction.

[ Regularly remove any accumulated
dust on the sunroof rail.

[ Dust accumulated between the
sunroof and roof panel can make
noise Open the sunroof and remove
dust regularly using a clean cloth.

[ Do not try to open the sunroof when
the temperature is below freezing
or when the sunroof is covered
with snow or ice. The sunroof may
not work properly and may break if
opened by force.

[ Do not open or drive with the sunroof
glass open immediately after rain or
washing the vehicle. Water may wet
the interior of the vehicle.

[ Do not extend any luggage outside
the sunroof while driving. Vehicle
damage may occur if the vehicle
suddenly stops.
WARNING
Do not extend your head, arms, body
parts or objects outside the sunroof
while driving. Injuries may occur if the
vehicle suddenly stops.
Resetting the Sunroof
OTMPH051003N
In some circumstances resetting the
sunroof operation may need to be
performed. Some instances where
resetting the sunroof may be required
include:
- When the 12-volt battery is either disconnected or discharged
- When the sunroof fuse is replaced
- If the sunroof one-touch AUTO OPEN/ CLOSE operation is not functioning
properly
