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 position with all doors, hood
and liftgate closed, the Aux. Battery
Saver+ activates according to the
auxiliary battery status.
Automatic Mode :
When the POWER button is in the
ON 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.

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 cancels
the 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.

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.

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 the
wires.
Also, do not touch the high
voltage electric wire (orange),
connector, and all electric
components and devices. This
may cause electric shock and
lead 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 the
leaked 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.
WARNING
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 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.

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 911 or an
authorized HYUNDAI dealer.
WARNING
If towing is required, lift all
four wheels off the ground
and tow the vehicle. If you
must tow the vehicle using
only two wheels, lift the front
wheels off the ground and tow
the vehicle.
(Continued)
(Continued)
If necessary to roll the vehicle
so that it can be rolled onto a
flatbed tow truck perform the
following:
- First, depress the brake
pedal and release the park-
ing brake.
- While depressing the brake
pedal shift to the N (Neutral)
position and press the
POWER button to turn the
vehicle off.
- Wait 3 minutes or more
before opening the driver
door and the vehicle will
remain in ACC mode and in
Neutral.
- If the driver door is opened
within the 3 minute period,
the vehicle will automatically
shift to P (Park), the vehicle
will turn OFF and the front
wheels will be remained
locked.WARNING

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 be
reduced.
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.
Service Plug
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
911 when towing the vehicle.
WARNING
OAEE069019
OAEEQ016057
Never touch the service plug in
the luggage compartment. The
service plug is attached to high
voltage battery system.
Touching the service plug will
result in death or serious injury.
Service personnel should fol-
low procedures in service man-
ual.
