Icy Road Warning Light(if equipped)
This warning light is to warn the driver
the road may be icy.
When the temperature on the out-
side temperature gauge is approxi-
mately below 4°C (40°F), the Icy
Road Warning Light and Outside
Temperature Gauge blinks and then
illuminates. Also, the warning chime
sounds 1 time.
The Icy Road Warning function can
be activated or deactivated from the
Vehicle Settings mode in the AVNscreen.
Information
If the icy road warning light appears
while driving, you should drive more
attentively and safely, refraining from
over-speeding, rapid acceleration, sud-
den braking or sharp turning, etc.
Hydrogen Gas Leak Warning Light
This warning light illuminates:
[Red] When the hydrogen leakage is detected in the vehicle.
[Yellow] When there is a malfunc- tion with the hydrogen leakage
detection sensor.
If the warning light continuously
remains on when the vehicle is in
"READY" state, or comes on during
driving, this indicates that there may
be hydrogen leakage or a malfunc-
tion with the hydrogen leakage
detection sensor. If this occurs, stop
the vehicle and have the hydrogen
system inspected by an authorized
HYUNDAI dealer.
Low Fuel Level Warning Light
This warning light illuminates:
When the fuel tank is nearly empty.
If the fuel tank is nearly empty:
Add fuel as soon as possible.

Average fuel economy/Instant fuel economy
Average Fuel Economy (1)
The average fuel economy is calcu- lated by the total driving distance and fuel consumption since the last
average fuel economy reset.
The average fuel economy can be reset both manually and automati-
cally. Manual reset
To clear the average fuel economy
manually, press the OK button on the
steering wheel for more than 1 sec-
ond when the average fuel economy
is displayed.
Automatic reset
To automatically reset the average
fuel economy, select between "AfterIgnition" or "After Refueling" in the
Vehicle Settings mode in the AVNscreen.
- After ignition: When the vehicle has
been OFF for 4 hours or longer the
average fuel economy will reset
automatically.
- After refueling: The average fuel economy will reset automaticallyafter refueling.
Information
The vehicle must be driven for a min-
imum of 300 meters (0.19 miles) since
the last ignition key cycle before the
average fuel economy will be recalcu-
lated.
Instant Fuel Economy (2)
The instantaneous fuel economy is displayed according to the bar
graph in the LCD display while
driving.

Air conditioning
Your HYUNDAI vehicle air condition- ing system is filled with R-1234yf
refrigerant.
1. Start the vehicle.
2. Press the air conditioning button.
3. Select the Face Level mode.
4. Set the air intake control toRecirculation mode temporarily to
allow the cabin to cool quickly.
When the desired temperature inthe cabin is reached, change the
air intake control back to Fresh
mode.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
MAX A/C position, then set the fanspeed control to the highest setting. When using the air conditioning
system, monitor the temperature
gauge closely while driving up
hills or in heavy traffic when out-
side temperatures. Air condition-
ing system operation when climb-ing a steep grade or in high out-side ambient temperatures can
cause fuel cell stack overheating.
Continue to use the fan, but turn the air conditioning system off if
the temperature gauge indicates
fuel cell stack overheating.
Air conditioning system operation
tips
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
After sufficient cooling has been achieved, switch back from recircu-
lation mode to fresh mode. To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the airconditioning system with the win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
If you operate air conditioner exces- sively, the difference between the
temperature of the outside air andthat of the windshield could cause
the outer surface of the windshield
to fog up, causing loss of visibility. In
this case, set the mode selection
knob or button to the position
and fan speed control to the lowerspeed.

ment cluster, the drive mode will be in
NORMAL mode and may not change
to ECO mode. The mode changes, as below,
whenever the DRIVE MODE buttonis pressed.
Press and hold the DRIVE MODE
button to select ECO+ mode.ECO mode
ECO mode improves bat-tery charge use efficiency
for eco-friendly driving.
When ECO mode is selected by pressing the DRIVE MODE button,
the ECO indicator (green color) will

If the vehicle is set to ECO mode, when the vehicle is turned OFF
and restarted the Drive Mode set-
ting will remain in ECO mode.
Information
Battery charge use efficiency depends
on the driver's driving habit and road
condition. When ECO mode is activated:
The acceleration response may be
slightly reduced as the accelerator
pedal is depressed moderately.
The air conditioner performance may be limited.
The above situations are normalconditions when ECO mode is acti-
vated to improve fuel efficiency.
