WARNING
• Immediately stop charging when
you find abnormal symptoms (odor,
smoke).
• Replace the charging cable if the
cable coating is damaged to prevent electrical shock.
• When connecting or removing the
charging cable, make sure to hold
the charging connector handle and
charging plug.
If you pull the cable itself (without
using the handle), the internal wires
may disconnect or get damaged. This
may lead to electric shock or fire.
CAUTION
• Always keep the charging connector
and charging plug in clean and
dry condition. Be sure to keep the
charging cable in a condition where
there is no water or moisture.
• Be sure to use only certified electric
vehicle charger. Using uncertified
charger may cause the damage to
the vehicle.
• Before charging the battery, turn the
vehicle OFF.
• When the vehicle is switched OFF
while charging, the cooling fan
inside the motor compartment may
automatically operate. Do not touch
the cooling fan while charging.
• Be careful not to drop the charging
connector. The charging connector can be damaged.
Unlock Charging Door in
Emergency
ONE1Q011045
If the charging door does not open due
to battery discharge and failure of the
electric wires, open the liftgate and
slightly pull the emergency cable as
shown above. The charging door will then open.

Charging the eleCtriC vehiCle (abrupt stop)
Action to be taken when charging stops abruptly
When the high voltage battery does not charge, check the followings:
1. Check the charging setting for the vehicle. Refer to “Charge Management”, in this chapter (for example, When scheduled charging is set, charging is not initiated
immediately when the AC charger or portable charger (ICCB: In-Cable Control Box)
is connected.)
2. Check the operation status of AC charger, portable charger and DC charger. (Charging Status Indicator Lamp for Portable Charger, refer to “Checking Charging
Status” for trickle charge in this chapter.)

à Actual method for indicating the charging status may vary in accordance with the
charger manufacturer.
3. When the vehicle does not charge and a warning message appears on the cluster, check the corresponding message. Refer to “LCD Display Messages”, in this chapter.
4. If the vehicle is properly charged when charged with another normally working
charger, contact the charger manufacturer.
5. If the vehicle does not charge when charged with another normally working charger, contact an authorized HYUNDAI dealer for inspection.
6. If charging fails and the service warning light (
) is lit in the cluster, contact an
authorized HYUNDAI dealer.

Virtual Engine Sound System
The Virtual Engine Sound System
generates engine sound for pedestrians
to hear vehicle sound because there is
no sound while the Electric Vehicle (EV)
is operating. • If the vehicle is in the ready (
)
mode and the gear is not in P (Park),
the VESS will be operated.
• When the gear is shifted to R
(Reverse), an additional warning
sound will be heard.
CAUTION
• The vehicle is much quieter while
driving than a conventional gasoline-
powered vehicle. Be aware of your
surroundings and always drive safely.
• After you park the vehicle or while
you are waiting at a traffic light,
check whether there are children or
obstacles around the vehicle.
• Check if there is something behind
the vehicle when driving in reverse.
Pedestrians may not hear the sound
of the vehicle.
Distance to Empty
ONE1Q011049E
The distance to empty is displayed
differently according to the selected
drive mode in the Drive Mode Integrated
Control System.
For more information, refer to “Drive
Mode Integrated Control System” in
chapter 6.
When destination is not set • On average, a vehicle can drive about
199 miles (320 km) (Standard type) /
249 miles (400 km) (Extended type).
• Under certain circumstances where
the air conditioner/heater is ON,
the distance to empty is impacted,
resulting in a possible distance range
from 106 ~ 286 miles (170 ~ 460 km)
(Standard type) / 130 ~ 354 miles
(210 ~ 570 km) (Extended type).
When using the heater during cold
weather or driving at high speed, the
high voltage battery consumes a lot
more electricity. This may reduce the
distance to empty significantly.
• After ‘0 km’ has been displayed,
the vehicle can drive an additional
2~5 miles (3~8 km) depending on
driving speed, heater/air conditioner,
weather, driving style, and other
factors.

ONE1Q011011
When the remaining battery is lower than
10 % on the SOC gauge, the warning light (
) turns ON to alert you of the battery
level.
When the warning light (
) turns ON,
the vehicle can drive an additional 18 ~
25 miles (30 ~ 40 km) depending on the
driving speed, heater/air conditioner,
weather, driving style, and other factors.
Charging is required.
NOTICE
When the high voltage battery range
shows 25 ~ 30 miles (40 ~ 50 km),
the vehicle speed is limited and then
eventually the vehicle will turn OFF.
Charge the vehicle immediately.
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+ activates
maximum of 20 minutes. If the Aux. Battery Saver+ function activates
more than 10 times consecutively, in
the Automatic Mode the function will
stop activating, judging that there is
a problem with the auxiliary battery.
In this case, drive the vehicle for some
period of time. The function will start activating if the auxiliary battery
returns to normal.
• 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 the high voltage battery level
may have decreased.

WARNING
ONE1Q011038
When the function is activating the
indicator lamp will illuminate and high
voltage electricity will be flowing in the
vehicle. 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. Also, do not modify your
vehicle in any way. This may affect your
vehicle performance and lead to an
accident.
