HEV mode to allow heating or air
conditioning. It is when the coolant
temperature is low (below -14°C)
and the driver turns on the heating or
cooling system.
If the coolant temperature gets high-
er than -14°C or the driver turns off
the heating or cooling system the
vehicle returns to its default (EV)
mode.

Safety Precautions
High Voltage Battery SystemNever touch orange coloured or
high voltage labelled 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
Whilst 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.

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 a HYUNDAI autho-
rised repairer.
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
luggage compartment. Such
an attempt may distort the
high voltage battery case,
causing a safety problem or
degrading the performance.
Be careful when loading flam-
mable liquid in luggage com-
partment. It could cause oper-
ational and safety degrada-
tion if the liquid leaks and
flows in high voltage battery.
CAUTION
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 bat-
tery system, serious injury or
death may occur.
