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.

ONE1Q011011
When the remaining battery is lower than
10 % on the SOC gauge, the warning light (
) turns ON to alert you of the battery
level.
When the warning light (
) turns ON,
the vehicle can drive an additional 18 ~
25 miles (30 ~ 40 km) depending on the
driving speed, heater/air conditioner,
weather, driving style, and other factors.
Charging is required.
NOTICE
When the high voltage battery range
shows 25 ~ 30 miles (40 ~ 50 km),
the vehicle speed is limited and then
eventually the vehicle will turn OFF.
Charge the vehicle immediately.
Aux. Battery Saver+
The Aux. Battery Saver+ is a function that
monitors the charging status of the 12 V
auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges the
auxiliary 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.

Power Down Warning Light
This warning light illuminates:
• When the Start/Stop button is in the ON position.
- It illuminates for approximately 3 seconds and then goes off.
• When the power is limited for the
safety of the high-powered parts of an
electric vehicle. The power is limited
for the following reasons.(Unless both
Service Warning Light and Power
Down Indicator Light illuminate at the
same time, it is not a failure.)
- The high voltage battery level is too low or voltage is decreasing
- The temperature of the high voltage battery is too high or too low
- The temperature of the motor is high
NOTICE
• Do not accelerate or start the vehicle
suddenly when the power down
warning light is ON.
• When the power is limited for the
safety of the high-powered parts of
an electric vehicle, the power down
indicator light illuminates. your
vehicle may not drive uphill or skid
on a slope with the indicator light ON. Charging Indicator Light
This warning light illuminates:
•
When charging the high voltage
battery.
High Voltage Battery Level
Warning Light
This warning light illuminates:
• When the high voltage battery level
is low.
• When the warning light turns ON,
charge the battery immediately.
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.

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 0%, this
warning message is displayed.
The warning light on the instrument
cluster (
) and the power down
warning light () 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.
Power limited due to low EV batter
temperature. Charge battery
OOSEV040507L
Both warning messages are displayed
to protect electric vehicle system when

If an Accident Occurs
WARNING
• When a vehicle accident occurs,
move the vehicle to a safe place,
turn OFF the vehicle and disconnect
the high voltage cut-off switch from
the auxiliary battery (12V) to prevent
high voltage electricity from flowing.
• If electric wires are exposed from
inside or outside the vehicle, do not
touch the wires.
Also, do not touch the high voltage
electric wire (orange), connector,
and all electric components and
devices. This may cause electric
shock and lead to injuries.
WARNING
• When a vehicle accident occurs and
the high voltage battery is damaged,
harmful gas and electrolytes may
leak. Be careful not to touch the
leaked liquid.
• When you suspect leakage of
inflammable gas and other harmful
gases, open the windows and
evacuate to a safe place. If any
leaked fluid comes in contact with
your eyes or skin, immediately clean
the affected area thoroughly with
tap water or saline solution and
have doctors inspect it as soon as possible.
WARNING
• If a small scale fire occurs, use a fire
extinguisher (ABC, BC) that is meant
for electrical fires. If it is impossible
to extinguish the fire in the early
stage, remain a safe distance from
the vehicle and immediately call your
local fire emergency responders.
Also, advise them that an electric
vehicle is involved.
• If the fire spreads to the high
voltage battery, large amount of
water is needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.
WARNING
If you cannot put out the fire
immediately, the high voltage battery
may explode. Evacuate to a safe place
and do not let other people approach
the site.
Contact the fire department and notify
them of an electric vehicle fire. • If the vehicle is flooded with water,
immediately turn off the vehicle and
evacuate to a safe place. Contact
the fire department or an authorized
HYUNDAI dealer.

WARNING
ONE1081011
[A] : Dollies
ONE1081015
• If towing is required, lift all four
wheels off the ground and tow the
vehicle. If you must tow the vehicle
using only two wheels, lift the front
wheels off the ground and tow the
vehicle.
• If you tow the vehicle while the
rear wheels are touching the
ground, the vehicle motor may
generate electricity and the motor
components may be damaged or a
fire may occur.
• When a vehicle fire occurs due to the
battery, there is a risk of a second
fire. Contact the fire department
when towing the vehicle.
Other Precautions for Electric
Vehicle
• When you paint or apply heat
treatment to the vehicle as a result of
an accident, the performance of the
high voltage battery can be reduced.
• If heat treatment is required, contact
an authorized HYUNDAI dealer.
• When you clean the motor
compartment, do not use high
pressure water to wash. This may
cause an electric shock due to a
discharge in high voltage electricity,
or damage the vehicle’s electric
system.
• Use, remodel, or install genuine
Hyundai part or the equivalent (of
the genuine part) specified for your
vehicle.
