• The driving habits: The driving speed and tendency of accelerating and decelerating. High speed driving or frequent accelerating and decelerating reduces the distance to
empty.
• The power usage: Additional power use, such as the air conditioner, heater, lights, etc. As the power usage increases, the distance to empty reduces.
• The driving conditions: The weather, temperature, and terrain. If you drive in snow/rain/strong wind or low temperature, the distance to empty will be reduced. The
distance to empty will also be reduced when driving uphill or on slippery or rough
roads.
• The high voltage battery energy: Proportional to the State of Charge (SOC), but may vary depending on the battery temperature and the State of Health (SOH) of a battery.
Change in the distance to empty when 100 % charged
In case the distance to empty has been reduced due to learning of the driving habit or the
driving conditions, you can increase the distance to empty again by continuously driving
following the “Tips for enhancing the distance to empty”.
• Resetting the previously learned driving patterns at the service center may increase the distance to empty displayed on the bottom of the instrument cluster, but it does
not increase the actual distance to empty. The distance to empty may not be accurate
until the learning proceeds.
• If the high voltage battery temperature is low in winter, the distance to empty reduces but it is not a permanent change. The distance to empty will increase again once the
temperature rises.
• If you reduce the power usage, the distance to empty will increase.
• Natural degradation may occur with the high voltage battery depending on the number of years the vehicle is used. This may reduce the distance to empty.
When setting a destination
When the destination is set, the distance to empty may change because the distance to
empty is recalculated using the information of the destination instead of the learned
electric energy economy history.
Information The distance to empty may vary significantly based on traffic conditions or driving speed.

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.

Checking the real time energy status (CHARGE/POWER gauge)
The CHARGE/POWER gauge displays the charging and discharging status of the electric
energy produced by the regenerative braking and the energy consumption of the electric
motor.
B0002902
•CHARGE : Shows the charging status of the electric motor when vehicle is decelerating
or driving on a downhill road (being charged by the regenerative brakes). The more
electric energy is charged, the lower the gauge level.
• POWER : Shows discharging status of the electric motor when vehicle is accelerating or
driving on an uphill road. The more electric energy is discharged (used), the higher the
gauge level.
Checking the State of Charge (SOC)
The SOC indicator is displayed at the bottom of the CHARGE/POWER gauge and shows
the charge level of the high voltage battery as a percentage. The lower the number, the
more the vehicle needs to be charged, and 100 % indicates a full charge.

• 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.
CAUTION If the warning light illuminates while driving or does not go off, have the vehicle
inspected by an authorized HYUNDAI dealer.

measures.
Warning LightCauseMeasure
Service warning light This warning light illuminates:
• When there is a problem with
related parts of the electric
vehicle control system, such
as sensors, etc.
• When an actuator, electric compressor for air
conditioning, etc.
malfunctions. In a normal condition, it
illuminates for about 3 seconds
when the Start/Stop button is in
the ON position and then goes
off.
• When the warning light
illuminates while driving, or
does not go off after starting
the vehicle, have your vehicle

properly drive uphill.
High voltage battery level warning light This warning light illuminates
when the high voltage battery
level is low. Immediately charge the
vehicle. The vehicle can drive
an additional 18-31 mi. (30-50
km).
• The actual distance to empty
depends on the driving
conditions.
Regenerative brake warning light This warning light illuminates
when the regenerative brake
