EV Charging Troubleshooting - Steps to Consider
If the vehicle fails to charge after being plugged in to a charging station or if plugged in when using the portable charger,
check the following:
1. Verify the charge mode is set to immediate. (i.e. confirm that scheduled charging is turned OFF)
2. Check the operation status of the charging station or the portable charger.
3. Check to see if there are any warning messages in the LCD cluster. Refer to "LCD Display Messages" in this sec-
tion.
4. If there is an error message on the charging station display screen, there may be a problem with the charging sta-
tion. Try to charge the vehicle with a different charging station.
5. If the vehicle fails to charge with different charging station equipment, there may be a problem with the vehicle.
Contact an authorized HYUNDAI dealer for inspection.

How to Start the Vehicle
1. Holding the smart key, sit in the
driver's seat.
2. Fasten the seat belt before start-
ing the vehicle.
3. Make sure to engage the parking
brake.
4. Turn OFF all electrical devices.
5. Make sure to depress and hold
the brake pedal.
6. While depressing the brake
pedal, shift to P (Park).
7. Depress and hold the brake while
pressing the POWER button.8. When the " " indicator is ON,
you can drive the vehicle.
When the " " indicator is OFF,
you cannot drive the vehicle. Start
the vehicle again.
9. Depress and hold the brake pedal
and shift to the desired position.
Information
While the charging cable is connected,
the gear cannot be shift from P (Park)
to any other gear for safety reasons.
10. Release the parking brake and
slowly release the brake pedal.
Check if the vehicle slowly moves
forward, then depress the accel-
erator pedal.
How to Stop the Vehicle
1. Hold down the brake pedal while
the vehicle is parked.
2. While depressing the brake pedal,
shift to P (Park).
3. While depressing the brake pedal,
engage the parking brake.
4. While depressing the brake pedal,

Tips for Improving Distance to
Empty
If you operate the air conditioner
/heater too much, the driving battery
uses too much electricity. This may
reduce the distance to empty.
Therefore, it is recommended that
you set the cabin temperature to
73°F (23°C) AUTO. This setting that
has been certified by various
assessment tests to maintain opti-
mal energy consumption rates while
keeping the temperature fresh.
Turn OFF the heater and air condi-
tioner if you do not need them.
Depress and hold the accelerator
pedal to maintain speed and drive
economically.
Gradually depress and release the
accelerator pedal when accelerat-
ing or decelerating.
Always maintain specified tire
pressures.
Do not use unnecessary electrical
components while driving.
Do not load unnecessary items in
the vehicle.
Do not mount parts that may
increase air resistance.
Power/Charge Gauge
The Power/Charge Gauge shows the
energy consumption rate of the vehi-
cle and the charge/discharge status
of the regenerative brakes.
POWER :
It shows the energy consumption rate
of the vehicle when driving uphill or
accelerating. The more electric ener-
gy is used, the higher the gauge level.
CHARGE :
It shows the charging status of the
battery when it is being charged by
the regenerative brakes (decelerat-
ing or driving on a downhill road).
The more electric energy is charged,
the lower the gauge level.
State of Charge (SOC) Gauge
for High Voltage Battery
The SOC gauge shows the charg-
ing status of the high voltage bat-
tery.
"L (Low)" position on the indicator
indicates that there is not enough
energy in the high voltage battery.
"H (High)" position indicates that
the driving battery is fully charged.
When driving on highways or
motorways, make sure to check in
advance if the driving battery is
charged enough.

When there are 4~5 gauge bars
(near the "L (Low)" area) on the SOC
gauge, the warning lamp turns ON to
alert you of the battery level.
When the warning lamp turns ON,
the vehicle can drive an additional
18~25 miles (30~40 km) depending
on the driving speed, heater/air con-
ditioner, weather, driving style, and
other factors. Charging is required.When the high voltage battery
level is low, the power down warn-
ing illuminates and the power out-
put from the vehicle is limited.
Charge the battery immediately
since your vehicle may not drive
uphill or skid on a slope with the
warning light ON.
Warning and Indicator
Lights (related to elec-
tric vehicle)
Ready Indicator
This indicator illuminates :
When the vehicle is ready to be driven.
- ON : Normal driving is possible.
- OFF : Normal driving is not possible,
or a problem has occurred.
- Blinking : Emergency driving.
When the ready indicator goes OFF
or blinks, there is a problem with the
system. In this case, have your vehi-
cle inspected by an authorized
HYUNDAI dealer.

If this warning message appears,
check if there is a problem with the
charging cable or connector, or if
there is an error message on the
charging station display screen.
If the same problem occurs when
charging the vehicle with a normally
operating AC charger or genuine
HYUNDAI portable charger, have
your vehicle inspected by an author-
ized HYUNDAI dealer.Charging Stopped.
Check the cable connection
This warning message is displayed
when charging is stopped because
the charging connector is not cor-
rectly connected to the vehicle
charging port.
If this message is displayed, discon-
nect the charging cable from the
vehicle charging port and reconnect
it. Before reconnecting, check to
make sure there is no foreign debris
or damage to the connector or
charging port on the vehicle.If the same problem occurs when
charging the vehicle with a replaced
charging cable or genuine HYUNDAI
portable charger, we recommend
that you have your vehicle inspected
by an authorized HYUNDAI dealer.
