Information
Gradual capacity reduction of the
high voltage battery.
The high voltage Battery capacity
gradually reduces with time and use.
This is natural characteristic of the
high voltage batteries. The extent at
which capacity is reduced changes
drastically depending on the environ-
ment(ambient temperature, etc.) and
usage conditions such as how the vehi-
cle is driven and how the high voltage
battery is charged. Reduction of the
high voltage battery capacity is not
covered under warranty.
Safety Plug High Voltage Battery Cooling
Duct
The high-voltage battery cooling duct
is located on the left side of the rear
seats.
i
Never touch the safety plug. The
safety plug is attached to high
voltage hybrid battery system.
Touching the safety plug will
result in death or serious injury.
Service personnel should follow
procedures in service manual.

(Continued)
Do not drop water or liquid on
to HPCU, HSG, motor and
fuses. The hybrid system com-
ponents are covered. If you
drop water or liquid on to
hybrid system compone nts, it
may result in electric shock.

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.
Information
Clean the cooling duct for the hybrid
battery with a dry cloth on a regular
basis.
i
(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.
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.(Continued)
WARNING

H50
If an Accident Occurs
When a submersion in water
occurs:
When your vehicle is flooded in
water, a high-voltage battery
may cause shock or fires. Thus,
turn the hybrid system OFF, take
the key in your possession and
escape to a safe place. Never
attempt physical contact with
your flooded vehicle.
Immediately contact an emer-
gency response team and
advise them that a hybrid vehi-
cle is involved.
WARNING
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.

When the Hybrid Vehicle Shuts
Off
When the high voltage battery is dis-
charged, when the 12-volt battery is
discharged, or when the fuel tank is
empty, the hybrid system may not
operate while driving. When the
Hybrid system does not operate, do
the followings:
1. Gradually reduce the vehiclespeed. Pull over your vehicle off
the road in a safe area.
2. Locate the shift lever in P (Park).
3. Turn ON the hazard warning flash- ers.
4. Turn OFF the vehicle, and try to start the hybrid system again,
while depressing the brake pedal
and turning on the Engine
Start/Stop button. 5. When the hybrid system still does
not operate, refer to ''If the 12 Volt
Battery Is Discharged'' in chapter 6.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For fur-
ther details, refer to ''If the 12 Volt
Battery Is Discharged'' in the
chapter 6. When the fuel level is
low, do not attempt to drive the
vehicle only with the battery
power. The high voltage battery
may be discharged, and the hybrid
system will turn OFF.
