Energy flow
The electric vehicle system informs
the drivers its energy flow in various
operating modes. While driving, the
current energy flow is specified in three modes.
Vehicle stop
OOSEV040481L
The vehicle is stopped.
(No energy flow)
EV propulsion
OOSEV040482L
Only the motor power is used to drive the
vehicle.
(Battery → Wheel) Regeneration
OOSEV040139L
The high-voltage battery is charged up
by the regenerative brake system.

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+ function will
be ON when the vehicle is delivered. If the function is not needed, you may turn it off in the Users Settings mode on the
cluster. For more information, refer to the following page.
Mode • Cycle Mode :
When the Start/Stop button is in
the OFF position with all doors,
hood and tailgate closed, the Aux.
Battery Saver+ periodically activates
according to the auxiliary battery
status.
• Automatic Mode :
When the Start/Stop button is in
the ON position with the charging
connector plugged in, the function
activates according to the auxiliary
battery status to prevent over
discharge of the auxiliary battery.
Information
• The Aux. Battery Saver+ activates
for a maximum of 20 minutes. If the Aux Battery Saver+ function activates
for more than 10 times consecutively in automatic mode, the function will
be disabled. (Note: There may be
a problem with the 12V auxiliary
battery.) If the vehicle is driven normally and
12V battery is able to charge normally,
the Aux. Battery Saver+ function will be enabled again.
• 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
OOSEV010011L
When the function is activating the
indicator lamp will illuminate and high
voltage electricity will be flowing in the
vehicle. 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. Also, do not modify your
vehicle in any way. This may affect your
vehicle performance and lead to an
accident.

If an accident occurs
WARNING
• When a vehicle accident occurs,
move the vehicle to a safe place,
turn OFF the vehicle and remove the
auxiliary battery (12 V) terminal 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 the
fire department. 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.

Dolly
• 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 necessary to roll the vehicle so that
it can be rolled onto a flatbed tow
truck perform the following:
- First, depress the brake pedal and
release the parking brake.
- While depressing the brake pedal
shift to the N (Neutral) position and
press the POWER button to turn
the vehicle off.
- Wait 3 minutes or more before
opening the driver door and the
vehicle will remain in ACC mode
and in Neutral.
- If the driver door is opened within
the 3 minute period, the vehicle
will automatically shift to P (Park),
the vehicle will turn OFF and the
front wheels will be remained
locked.
WARNING
OOS067022
• If you tow the vehicle while the
front 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.

Additional Precautions
• 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.
• Do not use, remodel, or install non-
genuine parts. This may damage the
electric power system.
Service Interlock Connector
OOSEV071131N
In case of emergency, cut the service
interlock connector cable to isolate the
high voltage of the battery.
WARNING
Never disconnect the service interlock
connector or cut the wire except in an
emergency situation.
Serious problems may occur, such as
the vehicle will not start.
Service Plug
OOSEVQ018022
DANGER
Never touch the service plug under the
rear seat.
The service plug is attached to the high
voltage battery system.
Touching the service plug will result in
death or serious injury.
Service personnel should follow
procedures in service manual.
