H57
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+ activatesfor a maximum of 20 minutes. If the
Aux Battery Saver+ function acti-
vates for more than 10 times consec-
utively in automatic mode, the func-
tion will be disabled. (Note: There
may be a problem with the 12V aux-
iliary battery.)
If the vehicle is driven normally and
12V battery is able to charge nor-
mally, the Aux. Battery Saver+
function will be enabled again.
• 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 devices are
used.
• If the Aux. Battery Saver+ function was activated, a message will be dis-
played on the instrument cluster

When the function is activating
the indicator lamp will illumi-
nate and high voltage electricity
will be flowing in the vehicle. Do
not touch the high voltage elec-
tric wire (orange), connector,
and all electric components 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 performance and lead to
an accident.

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 following
conditions 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 → Utility Mode‘ is
selected in the cluster.
System Activation
When the system is activated:
The indicator will turn off and the 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

If an Accident Occurs
When a vehicle accident
occurs, move the vehicle to a
safe place, turn OFF the vehi-
cle and disconnect the auxil-
iary battery (12 V) terminal to
prevent high voltage electrici-
ty from flowing.
If any electrical wires are
exposed from inside or out-
side the vehicle, do not touch
the wires.
Also, do not touch the high
voltage electrical wire (orange),
connector, and all electric com-
ponents 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.
If you suspect leakage of any
fluid or harmful gases, open
the windows and evacuate to
a safe place. If any leaked
fluid comes in contact with
your eyes or skin, immediate-
ly 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, a large
amount of water is needed to
put out the fire. Using small
amount of water or fire extin-
guishers not meant for electri-
cal fires could cause serious
injury or death from electrical
shock.
WARNING

H61
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.
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

Additional Precautions
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 Interlock Connector
In case of emergency, cut the service
interlock connector cable to isolate
the high voltage of the battery.

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.
