3. ‘Electronics’ shows the power and
energy consumption which are used
by the vehicle systems including the
cluster, infotainment system(speaker
and navigation), headlamp, vehicle
control unit, etc.
4. ‘Driving’ shows the total power
and energy consumption of the
driving motor’s driving energy and
regenerative energy.
Power/Charge Gauge
ONE1Q011050
The Power/Charge Gauge shows the
energy consumption rate of the vehicle
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 energy
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 (decelerating
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
ONE1Q011003
• The SOC gauge shows the charging
status of the high voltage battery.
• The low percentage number on the
indicator indicates that there is not
enough energy in the high voltage
battery. 100 % 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.

„„DC charge
OOSEV040500LOOSEV040501L
• This warning message is displayed
when charging is stopped for the
reasons below:
- There is a problem with the external AC charger or DC charger
- The external AC charger stopped charging
- The charging cable is damaged
In this case, check whether there is any
problem with the external AC or DC
charger and charging cable.
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 authorized
HYUNDAI dealer. Charging Stopped. Check the cable
connectionOOSEV040502L
This warning message is displayed
when charging is stopped because the
charging connector is not correctly
connected to the charging inlet
In this case, separate the charging
connector and re-connect it and check
whether there is any problem (external
damage, foreign substances, etc.) with
the charging connector and charging
inlet.
If the same problem occurs when
charging the vehicle with a replaced
charging cable or genuine HYUNDAI
portable charger, have your vehicle
inspected by an authorized HYUNDAI
dealer.
Check regenerative brakes
OOSEV040503E
This warning message is displayed when
the regenerative brake system does not
work properly.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.

Air bag warning light
This warning light illuminates:
•
When you set the Start/Stop button to the ON position.
- The air bag warning light illuminates for about 6 seconds and then turns
off when all checks have been
performed.
• The air bag warning light will remain
illuminated if there is a malfunction
with the Safety Restraint System (SRS)
air bag operation.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Regenerative brake warning
light
This warning light illuminates:
When the regenerative brake does not
operate and the brake does not perform
well. This causes the Brake Warning
light (red) and Regenerative Brake
Warning Light (yellow) to illuminate
simultaneously.
In this case, drive safely and have your
vehicle inspected by an authorized
HYUNDAI dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance can increase. Parking brake & brake fluid
warning light
This warning light illuminates:
•
When you set the START/STOP button in the ON position.
- It illuminates for approximately 3 seconds.
- It remains on if the parking brake is applied.
• When the parking brake is applied.
• When the brake fluid level in the
reservoir is low.
- If the warning light illuminates with the parking brake released, it
indicates the brake fluid level in the
reservoir is low.
• When the regenerative brake does not
operate.
If the brake fluid level in the reservoir is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the motor stopped, check the brake fluid level immediately and add
fluid as required (For more details,
refer to “Brake Fluid” section in
chapter 9) . After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found, or
if the warning light remains on, or if
the brakes do not operate properly, do
not drive the vehicle. Have the vehicle
inspected by an authorized HYUNDAI
dealer.

Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking system. This means you
still have braking on two wheels even if
one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
Also, the vehicle will not stop in as short
a distance with only a portion of the
brake system working.
If the brakes fail while you are driving,
shift to a lower gear for additional vehicle
braking and stop the vehicle as soon as it
is safe to do so.
WARNING
Parking Brake & Brake Fluid warning
light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake
& Brake Fluid warning light illuminates
with the parking brake released, it
indicates that the brake fluid level is
low.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer. Anti-lock Brake System (ABS)
warning light
This warning light illuminates:
•
When you set the Start/Stop button to the ON position.
- The ABS warning light illuminates for about 3 seconds and then goes
off.
• Whenever there is a malfunction with the ABS.
Note that the hydraulic braking
system will still be operational even if
there is a malfunction with the ABS.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Electronic Brake Force
Distribution (EBD) system
warning light
When the ABS warning and
Parking Brake warning lights are on
simultaneously, it may indicate a
problem with the Electronic Brake Force
Distribution system.
If this occurs, have the vehicle inspected
by an authorized HYUNDAI dealer.

WARNING
Safe Stopping • The TPMS cannot alert you to severe
and sudden tire damage caused by
external factors.
• If you notice any vehicle instability,
immediately take your foot off the
accelerator pedal, apply the brakes
gradually with light force, and slowly
move to a safe position off the road.
Forward safety warning light (if equipped)
This warning light illuminates:
• When you set the Start/Stop button to the ON position.
- The Forward Safety warning light illuminates for approximately 3
seconds and then goes off.
• Whenever there is a malfunction with
Forward Collision-Avoidance Assist.
If this occurs, have the vehicle inspected
by an authorized HYUNDAI dealer.
For more details, refer to “Forward
Collision-Avoidance Assist (FCA)”
section in chapter 7. Lane safety indicator light (if equipped)
This indicator light illuminates:
•
[Green] When Lane Keeping Assist
operating conditions are satisfied.
• [White] When Lane Keeping Assist
operating conditions are not satisfied.
• [Yellow] Whenever there is a
malfunction with Lane Keeping Assist.
If this occurs, have the vehicle
inspected by an authorized HYUNDAI
dealer.
For more details, refer to “Lane Keeping
Assist (LKA)” section in chapter 7.
All Wheel Drive (AWD)
warning light (if equipped)
This warning light illuminates:
Whenever there is a malfunction with the
AWD system.
If this occurs frequently, have the vehicle
inspected by an authorized HYUNDAI
dealer.
For more details, refer to "All Wheel
Drive (AWD)" section in chapter 6.

Check regenerative brakes
OOSEV040503E
These warning messages are displayed
when the regenerative brake system
does not work properly.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.
Low EV battery
OOSEV040505L
When the high voltage battery level
reaches below approximately 10 %, this
warning message is displayed.
The warning light on the instrument
cluster (
) will turn ON simultaneously.
Charge the high voltage battery
immediately. Charge immediately. Power limited
OOSEV040506L
When the high voltage battery level
reaches below approximately 5 %, this
warning message is displayed. The warning light on the instrument cluster (
) will turn on simultaneously.
The vehicle’s power will be reduced to
minimize the energy consumption of the
high voltage battery. Charge the battery
immediately.
