It shows the charging status of the
battery when it is being charged by
the regenerative brakes (decelerat-
ing 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
The SOC gauge shows the charging
status of the high voltage battery.
"L (Low)" position on the indicator
indicates that there is not enough
energy in the high voltage battery. "H
(High)" position indicates that the
driving battery is fully charged.
When driving on highways or motor-
ways, make sure to check in advance
if the driving battery is charged
enough.When there are 4~5 gauge bars
(near the "L (Low)" area) on the SOC
gauge, the warning lamp turns ON to
alert you of the battery level.
When the warning lamp turns ON,
the vehicle can drive an additional
18~25 miles (30~40 km) depending
on the driving speed, heater/air con-
ditioner, weather, driving style, and
other factors. Charging is required.

Air conditioning
Push the A/C button to manually turn
the system on (indicator light will illu-
minate) and off.
HEAT button
Push the HEAT button to turn the
heater on (indicator light will illumi-
nate).
Push the button again to turn the
heater off.
Air conditioner/Heater uses energy
from the battery. If you use the heater
or air conditioner for too long, dis-
tance to empty can be reduced due
to increased power consumption.
Turn off the heater and air conditioner
if not necessary.
EV mode (if equipped)
Push the EV button to enter the EV
mode on the infotainment system
screen.
The EV mode has a total of 7 menus
including Range, Nearby Stations,

System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or
rough roads, more frequent air condi-
tioner filter inspections and changes
are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air con-
ditioner refrigerant and com-
pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur. To
prevent damage, the air condition-
ing system in your vehicle should
only be serviced by trained and
certified technicians.

Vehicles equipped with R-134a
Since the refrigerant
is operated at very
high pressure, the air
conditioning system
should only be serv-
iced by trained and certified
technicians.
All refrigerants should be
reclaimed with proper equip-
ment.
Venting refrigerants directly to
the atmosphere is harmful to
individuals and environment.
Failure to heed these warnings
can lead to serious injuries.

For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired
while defrosting or defogging, set the
mode to the floor-defrost position.
Before driving, clear all snow and
ice from the windshield, rear win-
dow, side view mirrors, and all side
windows.
Clear all snow and ice from the
hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probability
of fogging up the inside of the wind-
shield.To Defog Inside Windshield
1. Select desired fan speed.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The outside (fresh) air position will
be selected automatically.
If the outside (fresh) air position is
not selected automatically, adjust the
corresponding button manually.
If the position is selected, lower
fan speed is adjusted to a higher fan
speed.

Windshield heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility could cause an acci-
dent resulting in serious or
death. In this case, set the mode
selection knob or button to the
position and fan speed con-
trol knob or button to a lower
speed.

Auto Defogging System
Auto defogging system reduces the
possibility of fogging up the inside of
the windshield by automatically
sensing the moisture of inside the
windshield.
The auto defogging system operates
when the heater or air conditioning is
on.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below 50 °F (10 °C).When the Auto Defogging
System operates, the indi-
cator will illuminate.
If higher level of moisture are sensed in
the vehicle, the Auto Defogging System
will operate in the following order:
Step 1 : Outside air position
Step 2 :Operating the air conditioning
Step 3 : Blowing air toward the wind-
shield
Step 4 : Increasing air flow toward
the windshield
If the air conditioning is off or recircu-
lated air position is manually select-
ed while Auto Defogging System is
ON, the Auto Defogging System
Indicator will blink 3 times to signal
that the manual operation has been
canceled.
To cancel or reset the
Auto Defogging System
Press the front windshield defroster
button for 3 seconds when the
POWER button is in the ON position.
When the Auto Defogging System is
canceled, ADS OFF symbol will blink
3 times and the ADS OFF will be dis-
played on the climate control infor-
mation screen.
When the Auto Defogging System is
reset, ADS OFF symbol will blink 6
times without a signal.
Information
• When the air conditioning is turned
on by Auto defogging system, if you
try to turn off the air conditioning, the
indicator will blink 3 times and the air
conditioning will not be turned off.
• For efficiency, do not select recircu-
lated air position while Auto defog-
ging system is operating.
• When Auto defogging mode is
selected, fan speed, temperature and
intake mode which is adjusted man-
ually are canceled for better defog-
ging result.

To prevent damage to the Power
Outlets :
Use the power outlet only when
the vehicle is in the ready ( )
mode and remove the accessory
plug after use. Using the acces-
sory plug for prolonged periods
of time with the vehicle off could
cause the battery to discharge.
Only use 12V electric acces-
sories which are less than 180 W
(Watts) in electric capacity.
Adjust the air-conditioner or
heater to the lowest operating
level when using the power outlet.
Close the cover when not in use.
(Continued)(Continued)
Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static
and malfunctions in other elec-
tronic systems or devices used
in your vehicle.
Push the plug in as far as it will
go. If good contact is not made,
the plug may overheat and the
fuse may open.
Plug in battery equipped electri-
cal/electronic devices with
reverse current protection. The
current from the battery may
flow into the vehicle's electrical/
electronic system and cause
system malfunction.
Wireless Cellular Phone
Charging System (if equipped)
There is a wireless cellular phone
charger inside the front console.
The system is available when all
doors are closed, and when the

Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between the MAX and the MIN
marks on the side of the coolant
reservoir when the parts in the motor
compartment is cool.
If the coolant level is low, have your
vehicle inspected by an authorized
HYUNDAI dealer. Use only designat-
ed coolant water for electric vehicles,
adding other types of water or
antifreeze can damage the vehicle.The electric motor for the cooling fan
is controlled by coolant temperature,
refrigerant pressure and vehicle
speed. As the coolant temperature
decreases, the electric motor will
automatically shut off. This is a nor-
mal condition.
OAEE076002L
Since a specific coolant water is
applied for electric vehicles,
replenishment of other
antifreeze or water may cause
problems to the vehicle.
WARNING
The electric motor for the cool-
ing fan may continue to operate
or start up when the vehicle is
not running and can cause seri-
ous injury. Keep hands, clothing
and tools away from the rotat-
ing fan blades of the cooling
fan.
