Information
An inappropriately disposed
battery can be harmful to the
environment and human
health. Dispose of the battery
according to your local law(s)
or regulations.
To prevent damage to your vehicle:
Only use a 12-volt power supply
(battery or jumper system) to
jump start your vehicle.
Do not attempt to jump start
your vehicle by push-starting.
Jump starting procedure
1. Position the vehicles close enough
that the jumper cables will reach,
but do not allow the vehicles to
touch.
2. Avoid fans or any moving parts in
the engine compartment at all
times, even when the vehicles are
turned off.
3. Turn off all electrical devices such
as radios, lights, air conditioning,
etc. Put the vehicles in P (Park)
and set the parking brake. Turn
both vehicles OFF.
Information
Your vehicle has a battery in the lug-
gage compartment, but when you
jump start your vehicle, use the
jumper terminal in the engine com-
partment.

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 an
electrical shock, an injury, or a
death may occur.
Any gas or electrolyte leakage
from your vehicle is not only
poisonous but also flammable.
Upon witnessing one of those,
open the windows, and remain
a safe distance from the vehi-
cle out of the road. Immediately
contact an authorized Hyundai
dealer and advise them that a
hybrid vehicle is involved.
If you need towing, refer to
"Towing" in the previous pages.
(Continued)
(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/flamma-
bles.
WARNING
If a fire occurs :
Upon witnessing any sparks,
gases, flames, or fuel leakage of
your vehicle, immediately call
911 or contact an authorized
HYNDAI dealer. Also, advise
them that a hybrid vehicle is
involved.
WARNING
When a submersion in water
occurs:
When your vehicle is flooded in
water, a high-voltage battery
may cause shock or may catch
on fire. Thus, turn the hybrid
system OFF, take the key in
your possession and move to a
safe place. Never attempt phys-
ical contact with your flooded
vehicle. Immediately contact an
authorized HYUNDAI dealer and
advise them that a hybrid vehi-
cle is involved.

Maintenance
To prevent SERIOUS INJURY or
DEATH to you or bystanders,
always follow these precautions
when working near or handling
the battery:
Always read and follow
instructions carefully
when handling a battery.
Wear eye protection
designed to protect the
eyes from acid splashes.
Keep all flames, sparks,
or smoking materials
away from the battery.
Hydrogen is always pres-
ent in battery cells, is
highly combustible, and
may explode if ignited.
Keep batteries out of
reach of children.
(Continued)
WARNING (Continued)
Batteries contain sulfu-
ric acid which is highly
corrosive. Do not allow
acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.
When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak. Lift with a battery
carrier or with your hands on
opposite corners.
Do not attempt to jump start
your vehicle if your battery is
frozen.
(Continued)
(Continued)
NEVER attempt to recharge
the battery when the vehicle’s
battery cables are connected
to the battery.
The electrical ignition system
works with high voltage.
NEVER touch these compo-
nents with the engine running
or when the Engine Start/Stop
button is in the ON position.

The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The elec-
tric motor is run by a high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric motor
or even both at the same time.
Fuel efficiency increases when the engine is off at idle, or when the vehicle is driven by the electric motor with the HEV
battery.
The HEV battery charge must be maintained, so at times the engine will come on even at idle to act as a generator.
Charging also occurs when decelerating or by regenerative braking.

Charging Information
•AC Charge :
The plug-in hybrid vehicle is
charged by plugging into a AC
charger installed in your home or a
public charging station. (For further
details, refer to the 'AC Charge'.)Trickle Charge :
The plug-in hybrid vehicle can be
charged by using household elec-
tricity. The electrical outlet in your
home must comply with regulations
and can safely accommodate the
Voltage / Current (Amps) / Power
(Watts) ratings specified on the
portable charge.
Charging Time Information
AC Charge :
Takes approximately 2 hours 15
minutes at room temperature. (Can
be charged to 100%.)
• Trickle Charge :
For charging at home. Please note
that Trickle Charger is slower than
the AC Charger.

Charging connector AUTO/LOCK
mode
The charging connector is locked in
the inlet at a different period accord-
ing to which mode is selected.
• LOCK mode : The connector locks
when the charging connector is
plugged into the charging inlet.
• AUTO mode : The connector locks
when charging starts.
For more details, refer to "Charging
Connector AUTO/LOCK Mode" in
this chapter.6. Connect the charging plug to the
electric outlet at a AC charging
station to start charging.7. Check if the charging indicator
light of the high voltage battery on
the instrument cluster is turned
ON. Charging is not done when
the charging indicator lamp is
OFF.
When the charging connector and
charging plug are not connected
properly, reconnect the charging
cable to charge.

Information
• Even though charging is possible
with the Engine Start/Stop button in
the ON/START position, for your
safety, start charging when the
Engine Start/Stop button is in the
OFF position and the vehicle shifted
to P (Park). After charging has
started, you can use electrical com-
ponents such as the radio by press-
ing the Engine Start/Stop button to
the ACC or ON position.
• During AC charging, the radio
reception may be bad.
• Moving the shift lever from P (Park)
to R (Reverse)/N (Neutral)/D
(Drive) stops the charging process.
To restart the charging process,
move the shift lever to P (Park),
place the Engine Start/Stop button
to the OFF position, and disconnect
the charging cable. Then, connect
the charging cable.8. After charging has started, the
estimated charging time is dis-
played on the instrument cluster
for about 1 minute.
If you open the driver seat door
while charging, the estimated
charging time is also displayed on
the instrument cluster for about 1
minute.
When scheduled charging is set,
the estimated charging time is dis-
played as "--".
Information
Depending on the condition and dura-
bility of the high voltage battery,
charger specifications, and ambient
temperature, the time required for
charging the battery may vary.
