Electric Vehicle
An electric vehicle is driven using a
battery and an electric motor. While
general vehicles use an internal
combustion engine and gasoline as
fuel, electric vehicles use electricalenergy that is charged inside the
high voltage battery. As a result,
electric vehicles are eco-friendly in
that they do not require fuel and do
not emit exhaust gases.
Characteristics of Electric
Vehicles
1. It is driven using the electricalenergy that is charged inside the
high voltage battery. This method
prevents air pollution since fuel,
like gasoline, is not required,
negating the emission of exhaust
gases.
2. A high performance motor is used in the vehicle as well. Compared
to standard, internal combustion
engine vehicles, engine noise and
vibrations are much more minimal
when driving.
3. When decelerating or driving downhill, regenerative braking is
utilized to charge the high voltage
battery. This minimizes energyloss and increases the distance to
empty.
4.When the battery charge is not suf- ficient, AC charge, DC charge and
trickle charge are available. (Refer
to “Charge Types for Electric
Vehicle” for details.) Information
What does regenerative braking do?
It uses the electric motor when decel-
erating or braking which transforms
vehicle motion (kinetic energy) to elec-
trical energy to charge the high volt-
age batteries. (Torque is applied in the
opposite direction when decelerating
to generate braking force and electric
energy.)
Battery Information
The vehicle is composed of a high voltage battery that drives the
motor and air-conditioner, and an
auxiliary battery (12 V) that drives
the lamps, wipers, and audio sys-tem.
The auxiliary battery is automati- cally charged when the vehicle is in
the ready ( ) mode or the high
voltage battery is being charged.

Aux. Battery Saver+
The Aux. Battery Saver+ is a function that monitors the charging status of
the 12 V auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges
the auxiliary battery.Information
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may
turn it off in the Users Settings mode
on the cluster. For more information,
refer to the following page.
Mode
Cycle Mode :
When the POWER button is in the
OFF or ACC position with all doors,
hood and tailgate closed, the Aux.
Battery Saver+ activates according
to the auxiliary battery status.
Automatic Mode :
When the POWER button is in the OFF position with the charging con-nector plugged in, the function acti-
vates according to the auxiliary bat-
tery status to prevent overdischarge
of the auxiliary battery. Information
 The Aux. Battery Saver+ activates maximum of 60 minutes. If the Aux.
Battery Saver+ function activates
more than 10 times consecutively
when in the automatic mode, the
function will stop activating, judg-
ing that there is a problem with the
auxiliary battery. In this case, drive
the vehicle for some period of time
or if the auxiliary battery returns to
normal, the function will start acti-
vating.
 The Aux. Battery Saver+ function cannot prevent battery discharge if
the auxiliary battery is damaged,
worn out, used as a power supply or
unauthorized electronic devises are
used.
 If the Aux. Battery Saver+ function was activated, the high voltage bat-
tery level may have decreased. i

System Setting
The driver can activate the Aux.
Battery Saver+ function by placing
the POWER button to the ON posi-
tion and by selecting: 'User Settings Other Aux.
Battery Saver+'
The Aux. Battery Saver+ function
deactivates, when the driver cancelsthe system setting.
Utility Mode
The high voltage battery is used
instead of the 12V auxiliary battery
for operating the convenient features
of the vehicle. When driving is not
necessary such as while camping or
when stopping the vehicle for a long
time, it is possible to use the electri-
cal devices (audio, lights, etc.) for
long hours.
System Setting and Activation
System setting
The driver can activate the Utility
Mode function when the followingconditions are satisfied.
The vehicle is in the ready ( ) mode and the gear is shifted to P
(Park).
The EPB (Electronic Parking Brake) is applied.
'User Settings Convenience
Utility Mode' is selected in the clus-
ter.When the function is activating
the third Charging Indicator
Lamp will blink and high voltage
electricity will be flowing in the
vehicle. Do not touch the high
voltage electric wire (orange),
connector, and all electric com-
ponents and devices. This may
cause electric shock and lead to
injuries. Also, do not modify
your vehicle in any way. This
may affect your vehicle per-
formance and lead to an acci-dent.

System Activation
When the system is activated:
The indicator will turn off andthe indicator will illuminate on
the cluster.
All electric devices are usable but the vehicle cannot be driven.
The EPB can be cancelled by pressing the EBP switch.
Note that the vehicle cannot be shifted out of P (Park). If a shift
attempt is made, a message"Shifting conditions not met" will be
displayed on the cluster.
System Deactivation
The Utility Mode can be deactivated
by pressing the POWER button to
the OFF position. The function can-
not be deactivated from the User
Settings mode.
If an Accident Occurs
When a vehicle accident
occurs, move the vehicle to a
safe place, turn OFF the vehi-
cle and remove the auxiliary
battery (12 V) terminal to pre-
vent high voltage electricity
from flowing.
If electric wires are exposed
from inside or outside the
vehicle, do not touch thewires.
Also, do not touch the high
voltage electric wire (orange),
connector, and all electric
components and devices. This
may cause electric shock andlead to injuries.
WARNING When a vehicle accident
occurs and the high voltage
battery is damaged, harmful
gas and electrolytes may leak.
Be careful not to touch theleaked liquid.
When you suspect leakage of
inflammable gas and other
harmful gases, open the win-
dows and evacuate to a safe
place. If any leaked fluid
comes in contact with your
eyes or skin, immediately
clean the affected area thor-
oughly with tap water or
saline solution and have doc-
tors inspect it as soon as pos-
sible.
