- Use a waterproof charger. Do not charge the vehicle in a place where rainwater may come in contact with the joints of the charging cable connector and the charging
plug.
- Ensure there is no water, dust, or other contaminants on the charging cable connector and the charging plug.
- Immediately stop charging if you feel abnormal conditions, such as odor or smoke.
- Do not charge the vehicle if there is a risk of lightning.

Information • While charging, the gear cannot be shifted from P (Park) to any other gear.
• Ensure the vehicle door is unlocked before disconnecting the charging connector. The release button on the charging connector does not work when the vehicle door is locked.
• To control the temperature of the high voltage battery while charging or when the battery temperature is high, the air conditioning is used to cool down the battery. It may generate noise
or vibration from operation of the air conditioning compressor and cooling fan, but this is a
normal condition when charging the high voltage battery.
• The cooling system may be operated when using the air conditioner during charging. This may degrade the air conditioner’s performance temporarily.
• 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.
• In rare cases, you might hear high-frequency noise (a small beeping sound) outside the vehicle when charging with a 400 V DC charger that has deteriorated or has long communication delay.
The high-frequency noise can be generated only when the vehicle tries to reduce its own
electromagnetic waves to keep DC charging as stable as possible. This beep sound does not
affect the charging performance or the vehicle itself.

Aux. Battery Saver+
The Aux. Battery Saver+ is a function that monitors the charging status of the 12 V battery.
If the 12 V battery level is low, the main high voltage battery charges the 12 V 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

Understanding virtual engine sound system
Electric vehicles do not use an internal combustion engine, so there is no engine noise
while driving. The Virtual Engine Sound System (VESS) generates engine sound to make
pedestrians aware of the approaching vehicle when driving.
• If the vehicle is in the ready ( ) mode and the gear is not in P (Park), the VESS is operated.
• When the gear is shifted to R (Reverse), an additional warning sound will be heard.
CAUTION • Be aware that the vehicle does not make engine noise while driving.
• Pay attention to the surrounding environment and drive carefully.
• After parking or waiting for a traffic light, please check around for children, or other obstacles before departure.
• When reversing, check directly behind you before driving. Pedestrians may not be able to recognize vehicle sounds.

Checking Electric Vehicle Driving Information
During vehicle operation, the instrument cluster displays the main information, such as
distance to empty, real-time energy status, battery charge level, and warning messages,
via the user interface and indicators.
Factors affecting the distance to empty
The distance to empty refers to the distance that can be driven by the current charged
battery level and is displayed on the bottom of the instrument cluster while driving the
electric vehicle.
B0002901
The distance to empty vary depending on many factors such as driving habits, power
usage, driving conditions, and high voltage battery. The distance to empty may be
increased or decreased from the certified figures as it reflects all the factors
comprehensively. Check the distance to empty considering the following:

Tips for enhancing the distance to empty
The distance to empty vary depending on the charge level of the high voltage battery,
weather, temperature, duration of the battery use, terrain, driving habits, etc.
You can increase the distance to empty by driving the vehicle following the instructions
below.
• The air resistance increases rapidly as the electric vehicle drives faster, so avoid speeding to increase the distance to empty and the electric energy economy.
• Rapid acceleration consumes a lot of driving energy and rapid deceleration limits the regenerative braking. Gradually depress and release the accelerator pedal when
accelerating or decelerating to maintain speed.
• If you operate the air conditioner or heater too much, the high voltage battery uses excessive electricity. This may reduce the distance to empty. Therefore, set the cabin
temperature to 72 °F (22 °C) AUTO level 2. Various assessment tests have been used to
verify that this setting maintains optimal energy consumption rates. Especially in
winter, reducing heating and using heated seats instead can significantly increase the
distance to empty. Turn off the air conditioner or heater if you do not need them.
• When using the air conditioner or heater, the energy consumption is reduced if recirculation mode is selected instead of fresh mode. Fresh mode requires a large
amount of energy consumption as the outside air has to be reheated or cooled.
• Close the windows while driving. Driving with the windows open increases air resistance and the usage of the air conditioner or heater.
• When using the air conditioner or heater while driving alone, use the DRIVER ONLY function.
• Always maintain specified tire pressures and use tires for electric vehicles.
• 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.
When the distance to empty is insufficient
• When the High voltage battery level warning light is displayed, immediately charge the vehicle at a nearby charging station.
• Drive energy efficiently following the “Tips for enhancing the distance to empty.”
• When the battery level is 0 %, do not try to drive. Move to a safe place and call for help.

• When the remaining battery of the high voltage battery is lower than 10 %, the warning light will be displayed.
• When the warning light is displayed, charge the vehicle.
Information • To find a nearby charging station, refer to the “Searching for nearby charging stations” in this chapter.
• Check if the SOC is enough before driving on highways.
• After the warning light is displayed, immediately charge the vehicle at a nearby charging station. The vehicle may not operate properly depending on the driving speed, weather, and
other driving conditions.

Checking the warning and indicator lights
The warning and indicator lights are displayed in the middle of the instrument cluster
before or while driving, depending on the status of the electric vehicle. Understand the
meaning of the warning and indicator lights referring to the instructions below and drive
safely.
