Charging precautions  
„ꢀAC Charger  
WARNING  
śꢀ Electromagnetic waves that are  
generated from the charger can  
seriously impact medical electric  
devices such as an implantable  
cardiac pacemaker.  
If you are fitted with any electronic  
medical implants (for example,  
cardiac pacemaker), make sure  
to ask the medical team and  
manufacturer whether charging  
your electric vehicle will impact  
the operation of electronic medical  
implants.  
OLFP0Q5007K  
„ꢀDC Charger  
śꢀ Check to make sure there is no  
water or dust on the charging  
cable connector and plug before  
connecting to the charger and  
charging inlet. Connecting whilst  
there is water or dust on the charging  
cable connector and plug may cause  
a fire or electric shock.  
WARNING  
OSQCEQ019005  
śꢀ Be careful not to touch the charging  
connector, charging plug, and the  
charging inlet when connecting  
the cable to the charger and the  
charging inlet on the vehicle.  
Actual charger image and charging  
method may vary in accordance with the  
charger manufacturer.  
śꢀ Comply with the following in order  
to prevent electrical shock when  
charging:  
- Use a waterproof charger.  
- Do not touch the charging  
connector and charging plug with  
your hands wet, or do not stand in  
water or snow whilst connecting  
the charging cable.  
- Be careful when there is lightning.  
- Be careful when the charging  
connector and plug are wet.

Disconnecting charging  
connector in emergency  
WARNING  
śꢀ Immediately stop charging when  
you find abnormal symptoms (odor,  
smoke).  
śꢀ Replace the charging cable if the  
cable coating is damaged to prevent  
electrical shock.  
śꢀ 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 be disconnected or get  
damaged. This may lead to electric  
shock or fire.  
ONE1Q011045  
If the charging connector does not  
disconnect from the charging inlet  
due to battery discharge and failure of  
electric wires, open the tailgate and  
slightly pull the emergency cable in the  
cargo area. The charging connector will  
be disconnected from the charging inlet.  
CAUTION  
śꢀ 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.  
śꢀ Be sure to use only certified electric  
vehicle charger. Using uncertified  
charger may cause the damage to  
the vehicle.  
śꢀ Before charging the battery, turn the  
vehicle OFF.  
śꢀ When the vehicle is switched OFF  
whilst charging, the cooling fan  
inside the motor compartment may  
automatically operate. Do not touch  
the cooling fan whilst charging.  
śꢀ Be careful not to drop the charging  
connector. The charging connector  
can be damaged.

How to Connect AC Charger  
AC charge  
„ꢀAC Charger  
1. Depress the brake pedal and apply the  
parking brake.  
2. Turn OFF all switches, shift to P (Park),  
and turn OFF the vehicle.  
If charging is initiated without the  
gear in P (Park), the charging will start  
after the gear is automatically shifted  
to P (Park).  
OLFP0Q5007K  
Actual charger image and charging  
method may vary in accordance with the  
charger manufacturer.

3. Open the charging door.  
For more details, refer to ‘Electric  
charging door’ in this chapter.  
Information  
If you cannot open the charging door due  
to freezing weather, tap lightly or remove  
any ice near the charging door. Do not try  
to forcibly open the charging door.

4. Check if there is dust on the charging  
connector and charging inlet.  
6. Connect the charging plug to the  
electric outlet at a AC charging station  
to start charging.  
5. Hold the charging connector handle  
and connect it to the vehicle charging  
inlet. Push the connector all the way  
in. If the charging connector and  
charging terminal are not connected  
properly, this may cause a fire.

8. After charging has started, the  
estimated charging time is displayed  
on the instrument cluster for about 1  
minute.  
If you open the driver seat door whilst  
charging, the estimated charging time  
is also displayed on the instrument  
cluster for about 1 minute. When  
scheduled charging or scheduled  
air conditioning/heating is set, the  
estimated charging time is displayed  
as “--” .  
OLFP0Q5007K  
1. When charging is complete, remove  
the charging plug from the electrical  
outlet of the AC charging station.  
Information  
śꢀ Depending on the condition and  
durability of the high voltage battery,  
charger specifications, and ambient  
temperature, the time required for  
charging the battery may vary.  
śꢀ In rare cases, you might hear high  
frequency noise (very little beep sound)  
outside the car when charging with  
400V fast charger that is deteriorated  
or has long communication delay.  
The high frequency noise can be  
generated only when the car tries to  
reduce its own electromagnetic waves  
to keep fast charging as possible.  
ONE1Q011044L  
2. Hold the charging connector handle  
and pull it out.  
So there is no need to worry about this  
little noise, because it is the intentional  
operation of the car that does not  
affect any charging performance or the  
vehicle itself at all.

DC charge  
„ꢀDC Charger  
Information  
To prevent charging cable theft,  
the charging connector cannot be  
disconnected from the inlet when the  
doors are locked or the charging connector  
is in the LOCK mode. Unlock all doors to  
disconnect the charging connector from  
the inlet.  
However, if the vehicle is in the charging  
connector AUTO mode, the charging  
connector automatically unlocks from the  
inlet when charging is completed.  
OSQCEQ019005  
If you attempt to disconnect the charging  
connector without pressing the release  
button, the connector and the inlet may  
be damaged. For more details, refer to  
“Charging Connector AUTO/ LOCK  
Mode” in this chapter.  
You can charge at high speeds at public  
charging stations. Refer to the respective  
company’s manual that is provided for  
each DC charger type.  
Battery performance and durability can  
deteriorate if the DC charger is used  
constantly.  
Use of DC charge should be minimised  
in order to help prolong high voltage  
battery life.  
If the release button does not work even  
after the all doors are unlocked, pull  
the emergency lift cable in the motor  
room and press the release button in the  
connector to disconnect it from the vehicle.  
If the release button still does not work,  
we recommend to consult an authorised  
HYUNDAI dealer.  
Actual charger image and charging  
method may vary in accordance with  
the charger manufacturer.  
3. Make sure to completely close the  
charging door.  
Information  
4. Close the protection caps of the  
charging connector and the charging  
plug to protect them from foreign  
substances.  
5. If the personal charging connector is  
used, store the connector in the cable  
compartment.  
If you use a DC charger when the vehicle  
is already fully charged, some DC  
chargers will send out an error message.  
When the vehicle is fully charged, do not  
charge the vehicle.

When the charging connector is not  
connected properly, reconnect the  
charging cable to charge it again.  
ONE1Q011040  
3. Open the charging door.  
During cold weather, DC charging  
may not be available to prevent high  
voltage battery degradation.  
For more details, refer to ‘Electric  
charging door’ in this chapter.  
Information  
Information  
If you cannot open the charging door due  
to freezing weather, tap lightly or remove  
any ice near the charging door. Do not try  
to forcibly open the charging door.  
To control the temperature of the high  
voltage battery while charging, the  
air conditioner is used to cool down  
the battery. It may generate noise or  
vibration from operation of the air  
conditioner compressor and cooling  
fan, but it is a normal condition when  
charging the high voltage battery. Also,  
the air conditioner’s performance may  
be degraded in summer due to operation  
of the cooling system to charge the high  
voltage battery. This is a normal condition.  
4. Check whether there is dust or foreign  
substances inside the charging  
connector and charging inlet.  
5. Hold the charging connector handle  
and connect it to the vehicle charging  
inlet. Push the connector all the way  
in. If the charging connector and  
charging terminal are not connected  
properly, this may cause a fire.
