- Fuel Cell Stack
Overheats
If the gauge pointer moves
beyond the normal range area
toward the "H" position, it indi-
cates overheating that may dam-
age the fuel cell stack.Hydrogen fuel gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank (The fuel tank capacity is
given in chapter 8). The fuel gauge is
supplemented by a low fuel warning
light which will illuminate when the
fuel tank is nearly empty.Information -Hydrogen
Fueling Station
According to the hydrogen fueling sta-
tion condition, the hydrogen fuel may
not filled fully.i
NOTICE
Running Out of Fuel
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the ''E'' (Empty)
level.
WARNING
Radiator Cap
Never remove the radiator cap
when the fuel cell power mod-
ule is hot. Otherwise the fuel
cell stack coolant may be under
pressure and cause severe
burns. Wait until the fuel cell
power module is cool before
adding coolant to the reservoir.

The modes, fan speeds, air intake
and air-conditioning will be con-
trolled automatically by the tem-
perature setting you select.
2. Press the temperature control but-
ton (1,2) to the desired tempera-
ture. If the temperature is set to
the lowest setting (Lo), the air con-
ditioning system will operate con-

The selected function will be con-
trolled manually while other functions
operate automatically.
For your convenience and to improve
the efficiency of the climate control,
use the AUTO button and set the
temperature to 72°F (22°C).
Never place anything near the
ambient light/solar sensor to
ensure better control of the heat-
ing and cooling system.
Manual Temperature Control
Mode
The heating and cooling system can
be controlled manually by pushing
buttons other than the AUTO button.
In this case, the system works
sequentially according to the order of
buttons selected.
When pressing any button except the
AUTO button while using automatic
operation, the functions not selected

System Operation
Cooling / Ventilation
1. Select the Face Level mode.
2. Set the air intake control to fresh
mode.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
Heating
1. Select the Floor Level mode.
2. Set the air intake control to fresh
mode.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
5. If desired, turn the air conditioning
ON with the temperature control
knob set to heat in order to dehu-
midify the air before it enters into
the cabin.
If the windshield fogs up, select the
Floor & Defrost mode or press
the Front Defrost mode.
Operation Tips
If dust or unpleasant fumes are
entering the car through the venti-
lation system, temporarily set the
air intake control to the recircula-
tion mode. Return the control to the
fresh mode when the unpleasant
air outside has diminished. This will
help keep the driver alert and com-
fortable.
To help prevent the inside of the
windshield from fogging, set the air
intake control to fresh mode and
the fan speed to the desired posi-
tion, turn on the air conditioning
system, and adjust the temperature
control to the desired temperature.
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 to
Recirculation mode temporarily to
allow the cabin to cool quickly.
When the desired temperature in
the 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 fan
speed control to the highest setting.

Convenient features of your vehicle
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 air
conditioning 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 and
that 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 lower
speed.
System Maintenance

For maximum defrost perform-
ance, set the temperature control
to the highest temperature setting
and the fan speed control to the
highest setting.
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.Automatic Temperature Control
System
To defog inside windshield
1. Select the desired fan speed.
2. Select the desired temperature.
3. Press the defroster button ( ).
4. Fresh mode will be selected auto-
matically.
Check to make sure the air intake
control is in Fresh mode. If the air
intake control LED is illuminated,
press the button once to enable
Fresh mode (LED OFF).

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 injury
or death. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
a lower speed.
