Safety system of your vehicle
Each time you push the switch, the
temperature setting of the seat is
changed as follows :
The seat warmer defaults to the OFF
position whenever the Engine Start/
Stop button is placed in the ON posi-
tion.
Information
With the seat warmer switch in the
ON position, the heating system in the
seat turns off or on automatically
depending on the seat temperature.
Battery Cooling Duct
The high voltage battery cooling duct
is located on the left side of the rear
seats. The cooling duct cools down
the high voltage battery.When the high voltage battery cool-
ing duct is blocked, the high voltage
battery may be overheated. Do not
obstruct the cooling duct with any
other objects.

Switching to Hybrid mode to
allow heating or air condition-
ing (Plug-in hybrid vehicle)
This message is displayed when the
vehicle automatically switches to
HEV mode to allow heating or air
conditioning. It is when the coolant
temperature is low (below 7 °F (-14
°C)) and the driver turns on the heat-
ing or cooling system.
If the coolant temperature gets high-
er than 7 °F (-14 °C) or the driver
turns off the heating or cooling sys-
tem the vehicle returns to its default
(EV) mode.
Maintaining Hybrid mode to
continue heating or air condi-
tioning (Plug-in hybrid vehicle)
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 temper-
ature is below 7 °F (-14 °C).
Low/High System Temp.
Maintaining Hybrid mode
(Plug-in hybrid vehicle)
This message is displayed when the
temperature of the high-voltage
(hybrid) battery is too low or too high.
This warning message is to protect
the battery and the hybrid system.

Maintenance
Information
The engine coolant and/or inverter
coolant level is influenced by the
hybrid system temperature. Before
checking or refilling the engine
coolant and/or inverter coolant, turn
the hybrid vehicle off.

■Engine coolant cap
■Inverter coolant cap
Never remove the
engine coolant cap
and/or inverter coolant
cap or the drain plug
while the engine and
radiator are hot. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the hybrid system off and
wait until the engine cools
down. Use extreme care when
removing the engine coolant
cap and/or inverter coolant cap.
Wrap a thick towel around it,
and turn it counterclockwise
slowly to the first stop. Step
back while the pressure is
released from the cooling sys-
tem. When you are sure all the
pressure has been released,
press down on the cap, using a
thick towel, and continue turn-
ing counterclockwise to remove
it.
WARNING
The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
Always turn off the engine
unless the vehicle has to be
inspected with the engine on.
Be cautious as the cooling fan
may operate if the negative (-)
battery terminal is not discon-
nected.

High Voltage Battery Cooling
Duct
The high-voltage battery cooling duct
is located on the left side of the rear
seats.The cooling duct cools down the
high-voltage battery. When the high-
voltage battery cooling duct is
blocked, the high-voltage battery
may be overheated and the vehicle
performance may become limited
and set a hybrid warning lamp. Do
not obstruct the cooling duct with any
other objects.

Never clean the cooling duct
of the hybrid battery with a
wet cloth. If any water enters
in the cooling duct of the
hybrid battery, the hybrid bat-
tery may cause an electric
shock, serious damage, injury
or death.
The hybrid battery is com-
posed of lithium-ion polymer.
If the hybrid battery is improp-
erly handled, it is dangerous
to the environment. Also it
may cause electrical shock
and severe burns, resulting in
serious injury or death.
Do not spill liquid over the
cooling duct of the hybrid bat-
tery. Doing so is very danger-
ous. It may cause electric
shock or serious injury.
Do not cover the cooling duct
with objects.

Information
Clean the cooling duct for the hybrid
battery with a dry cloth on a regular
basis.
If an Accident Occurs
i
For your safety, do not touch
high voltage cables, connec-
tors and package modules.
High voltage components are
orange in color.
Exposed cables or wires may
be visible inside or outside of
the vehicle. Never touch the
wires or cables, because it
can cause an electrical shock,
injury or death may occur.
Any gas or electrolyte leakage
from your vehicle is not only
poisonous but also flamma-
ble. Upon witnessing one of
those, open the windows, and
remain a safe distance from
the vehicle out of the road.
Immediately contact an emer-
gency response team and
advise them that a hybrid vehi-
cle is involved.
(Continued)
WARNING
(Continued)
When the vehicle is severely
damaged, remain a safe dis-
tance of 50 feet (15 meter) or
more between your vehicle and
other vehicles/flammables.
If a fire occurs :
If a small scale fire occurs, use
a fire extinguisher (ABC, BC)
that is meant for electrical fires.
If it is impossible to extinguish
the fire in the early stage,
remain a safe distance from the
vehicle and immediately call
911. Also, advise them that an
electric vehicle is involved.
If the fire spreads to the high
voltage battery, large amount of
water is needed to put out the
fire. Using small amount of
water or fire extinguishers not
meant for electrical fires could
cause serious injury or death
from electrical shocks.

(Continued)
Do not put any objects into
the cooling duct of the hybrid
battery. Doing so may cause
loss of cooling duct volume to
the hybrid battery. When the
cooling duct is blocked with
any objects, immediately con-
tact your HYUNDAI dealer.
Never place a container of liq-
uid on or near the cooling
duct. If the liquid spills, the
hybrid battery located in the
luggage compartment may be
damaged.
Secure all loads in the luggage
compartment to prevent them
from being tossed about
before driving. If a sharp or
heavy load impacts or pierces
the interior luggage compart-
ment wall, the hybrid battery
system may be damaged, dete-
riorating its performance.
