1 On-Board Charger (OBC)External device (low speed) to charge the high voltage battery2 InverterTransforms direct current into alternate current to supply power to 
the motor, and transforms alternate current into direct current to 
charge the high voltage battery.3 Low Voltage DC-DC Converter (LDC)Transforms power from the high voltage battery to low voltage (12V) 
to supply power to the vehicle (DC-DC).4 MotorUses electrical energy stored inside the high voltage battery to drive 
the vehicle (functions like an engine in a standard vehicle)5 Reduction GearDelivers rotational force of the motor to the tires at appropriate 
speeds and torque.6 High voltage battery (lithium-ion polymer)Stores and supplies power necessary for the electric vehicle to 
operate(12V auxiliary battery provides power to the vehicle features 
such as lights and wipers).

LOW TIRE PRESSURE INDICATORIlluminates if one or more of your tire is significantly under-inflated.TPMS MALFUNCTION INDICATORBlinks for approximately one minute, then remains illuminated when 
there is a malfunction with the TPMS. Inspect all Tires and adjust the 
Tire pressure to specification. If the lamp remains illuminated, we 
recommend the vehicle be checked by an authorized HYUNDAI dealer.LOW TIRE PRESSURE / TIRE PRESSURE MONITOR /
TPMS MALFUNCTION DISPLAY(LCD DISPLAY)Tire pressures will display after driving a short distance. If a tire 
pressure drops lower than predetermined specification, the Low Tire 
Pressure Indicator 
 will illuminate and the LCD  display will indicate
Tire(s) requiring air. Recommended tire pressure is located on the 
placard that can be found on the driver’s side door pillar.Low Tire Pressure /

DRIVING
AUTOMATIC WITH PUSH BUTTON DRIVE SELECTORREGENERATIVE BRAKE LEVEL CONTROL PADDLES
ELECTRONIC PARKING BRAKE (EPB)VIRTUAL ENGINE SOUND SYSTEM (VESS)
Select gear positions by pressing
the shift button. The gear position is
displayed in the instrument cluster.
For your safety, always depress the
brake pedal while shifting to another
gear.
The paddle shifter is used to adjust
the regenerative braking rate from 0
to 3 during decelerating or braking.
• Left side(      ): Increases 
regenerative braking and 
deceleration.
• Right side(      ): Decreases 
regenerative braking and 
deceleration.
The paddle shifter does not operate.
• When the two paddle shifters are
pulled at the same time.
• When the Cruise Control system
or Advanced Cruise Control
system is activated.The Virtual Engine Sound System (VESS) 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 moving at low speed, the VESS will operate.
• When the gear is shifted to R (Reverse), an additional warning
sound will be heard.
Applying
Stop the vehicle
then pull up the
EPB switch
Releasing
Press the EPB
switch while 
depressing the 
brake pedal.
Automatic releasing
• When shifted to P:
Depress the brake pedal and shift 
out of P to R or D.
• When shifted to N:
Depress the brake pedal and shift 
out of N to R or D.
NOTE:
  If necessary, emergency braking is possible by pulling up and 
holding the EPB switch.

IONIQ ELECTRIC HYUNDAI LANE DEPARTURE WARNING SYSTEM (LDWS)
The Lane Departure Warning System 
detects the lane on the road and 
warns the driver if the vehicle leaves 
the lane.  The system operates when 
the vehicle speed is over 40 mph.
•  To turn on the LDWS, press the
   LDWS switch.
• To turn off the LDWS, press the
   switch again.

The BSD (Blind Spot Detection) 
system uses a radar sensor to alert 
the driver while driving.
It monitors the rear area of the vehicle 
and provides information to the driver.1  Blind Spot Detection2  Lane Change Assist3  Rear Cross Traffic Alert
The system will activate if vehicle speed exceeds 20 mph.•  To turn on the BSD, press the BSD  
button (indicator  illuminated).
•  To turn off the BSD, press the BSD  
button again.
When the vehicle is in R (Reverse), the system provides an alert if a 
vehicle is approaching from the sides.Rear Cross Traffic AlertBLIND  SPOT  DETECTION  SYSTEM (BSD)

DRIVE  MODE  INTEGRATED  CONTROL  SYSTEM
You can select the drive mode
according to your preference or the
road condition.
The system initializes to the NORMAL
mode (except ECO mode)
after the vehicle is restarted.
Each time you press the button, the
drive mode is changed as follows :
Eco mode system helps to improve fuel efficiency. When the ECO 
mode system is activated, the vehicle acceleration, gear shift points 
and air conditioning perfomance will be reduced to conserve the fuel 
consumption.
ECO modeNormal mode provides regular daily driving performance with some 
fuel efficiency.NORMAL modeSport mode provides a sporty feel and may have heavier steering 
effort. In Sport mode, the fuel efficiency may decrease. SPORT mode
