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 : Limp home driving mode. When the ready indicator goes OFF
or blinks, there is a problem with the
system. In this case, have your vehi-
cle inspected by an authorized
HYUNDAI dealer.
Service Warning Light
This warning light illuminates :
When the Engine Start/Stop button is in the ON position.
- It normally flashes on momentar-ily for 3 seconds at Ready On and
should then stay off.
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, have your vehicle
inspected by an authorized HYUNDAI
dealer.

Regenerative Brake
Warning Light
This warning light illuminates :
When the regenerative brake is not
operating. This causes the Brake
Warning light (red) and Regenerative
Brake Warning Light (yellow) to illu-
minate simultaneously as soon as
possible .
In this case, drive safely and have
your vehicle inspected by an author-
ized HYUNDAI dealer.
The service brake still function, how-
ever, the operation of the brake pedal
may be more difficult than normal
and the braking distance can
increase.

Check regenerative brakes
This warning message is displayed
when the brake performance is low
or the regenerative brake does not
work properly due to a failure in the
brake system.
In this case, it may take longer for the
brake pedal to operate and the brak-
ing distance may become longer.
Check Virtual Engine SoundSystem
This message is displayed when
there is a problem with the VirtualEngine Sound System (VESS).
In this case, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Coasting guide (if equipped)
A chime will sound and the coasting
guide indicator will blink four times to
inform the driver when to take the
foot off from the accelerator by antic-
ipating a decelerating event* based
on the analysis of driving routes and
road conditions of the navigation. It
encourages the driver to remove foot
from the pedal and allow coasting
down the road with EV motor only.
This helps prevent unnecessary fuelconsumption and increases fuel effi-ciency

High Voltage Battery System
OLFHQ014002K
OLFHQ014009L
■ 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.

■ Drive Motor
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 assem-
ble the high voltage battery
system. Doing so may result
in electric shock, causing
death or serious injury.
If you disassemble or assem-
ble hybrid system compo-
nents improperly, it may dam-
age the performance and reli-
ability 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 exam-
ined by a doctor as soon as
possible.
WARNING (Continued)
Be careful when loading
inflammable liquid in trunk. Itcould cause operational and
safety degradation if the liq-
uid leaks and flows in high
voltage battery

When the vehicle is paint baked,
do not bake over 30 minutes in
70°C (158°F) or 20 minutes in
80°C (176°F) degree.
Do not wash the engine compart- ment, using water. Water may
cause an electric shock and may
damage electronic components.
NOTICE
Never assemble or disassemble
the high voltage battery system.
If you assemble or disassem-
ble the high voltage battery
system, the durability and per-
formance of the vehicle may be
damaged.
When you want to check the
high voltage battery system,
have the vehicle checked and
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 elec-
tric shock may occur. For your
safety, do not touch the cover
of electronic components and
electronic cable. Do not remove
the cover of electronic compo-
nents 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 mod-
ules (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 place 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.
