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

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.

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-

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.

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.

If you cannot put out the fire
immediately, the high voltage
battery may explode. Evacuate
to a safe place and do not let
other people approach the site.
Contact the fire department and notify them of an electric vehi-
cle fire.
If the vehicle is flooded with
water, immediately turn OFF
the vehicle and evacuate to a
safe place. Contact fire
department or an authorized
HYUNDAI dealer.

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 immedi-
ately contact fire department.
Also, advise them that an
electric vehicle is involved. If the fire spreads to the high
voltage battery, large amountof 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.

Other Precautions for Electric
Vehicle
When you paint or apply heat treat-ment to the vehicle as a result of
an accident, the performance of
the high voltage battery can bereduced. If heat treatment is required, contact
an authorized HYUNDAI dealer.
When you clean the motor com- partment, do not use high pressure
water to wash. This may cause an
electric shock due to a discharge in
high voltage electricity, or damage
the vehicle's electric system.
Do not use, remodel, or install non- genuine parts. This may damage
the electric power system.
If you tow the vehicle while
the front wheels are touching
the ground, the vehicle motor
may generate electricity and
the motor components may
be damaged or a fire may
occur.
When a vehicle fire occurs
due to the battery, there is a
risk of a second fire. Contact
fire department when towing
the vehicle.
