following instances occur:
- The smart key is close to a radiotransmitter such as a radio station
or an airport which can interfere
with normal operation of the
transmitter.
- The smart key is near a mobile two way radio system or a cellular
phone.

Fuel Filler Door
Opening the fuel filler door
1. Turn the vehicle off.
2. Push the fuel filler door openerbutton.
The fuel filler door does not open if the vehicle is not off.
The fuel filler door may open after several seconds from turning off
the vehicle. However, in cold
weather, the fuel door may not
open for about 45 seconds until
the cluster message "Powering
down..." disappears. This is for
protecting the fuel cell system. 3. Pull the fuel filler door (1) outward
to access the fuel filler cap.
4. Pull the fuel filler cap (2).
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.
Closing the fuel filler door
1. Cover the fuel filler with the cap.
2. Close the fuel filler door until it is latched securely.

If the fuel filler cap requires
replacement, you should use
parts for replacement from an
authorized Hyundai dealer. Anincorrect fuel filler cap canresult in a serious malfunc-tion of the fuel system or
emission control system. you
should contact your HYUNDAI
dealer for replacement.
If the fuel filler door is not
completely closed, the vehicle

Refueling dangers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines
carefully. Failure to follow these
guidelines may result in severe
personal injury, severe burns or
death by fire or explosion.
Read and follow all warning posted at the gas station facil-
ity.
Before touching the fuel noz-
zle, you should eliminate
potentially dangerous static
electricity discharge by touch-
ing another metal part of the
vehicle, a safe distance away
from the fuel filler neck, noz-
zle, or other gas source.
Do not get back into a vehicle
once you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or
fabric (polyester, satin, nylon,
etc.) capable of producing stat-
ic electricity. Static electricity
discharge can ignite fuel
vapors resulting in rapid burn-
ing. If you must reenter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other gasoline
source.
Do not use cellular phones
while refueling. Electric current
and/or electronic interference
from cellular phones can
potentially ignite fuel vapors
causing a fire.
When refueling, always shut
the power off. Once refueling
is complete, check to makesure the filler cap and filler
door are securely closed,
before starting the vehicle.
DO NOT use matches or a
lighter and DO NOT SMOKE or
leave a lit cigarette in your
vehicle while at a gas station
especially during refueling.
Automotive fuel is highly
flammable and can, when
ignited, result in fire.
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gasstation and then contact the
local fire department. Follow
any safety instructions they
provide.

cluster while driving. Doing socould lead to driver distraction
which may cause an accident
and lead to vehicle damage,
serious injury, or death.

Power gauge
The power gauge shows the energy
consumption rate of the traction
motor.
CHARGE : It shows the chargingstatus 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.
ECO : It shows the energy con- sumption rate during normal driv-ing condition. POWER : It shows the energy con-
sumption rate of the vehicle when
driving uphill or accelerating. The
more electric energy is used, the
higher the gauge level.
Fuel cell stack temperature
gauge
This gauge shows the temperature
of the fuel cell stack coolant when
the POWER button is ON.
Do not continue driving with an over-
heated fuel cell stack. If your vehicle
overheats, have the vehicle inspected
by an authorized HYUNDAI dealer.

- Fuel Cell StackOverheats
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 thefuel tank (The fuel tank capacity is
given in chapter 8). The fuel gauge is
supplemented by a low fuel warninglight which will illuminate when the
fuel tank is nearly empty. Information -
HydrogenFueling 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 possibleafter 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.

Outside temperature gauge
This gauge indicates the current out-
side air temperature by 1 degrees C
(1 degrees F).
- Temperature range :-40°C ~ 60°C (-40°F ~ 140°F)
Note that the temperature indicated
on the LCD display may not change
as quickly as the outside tempera-
ture (there may be a slight delay
before the temperature changes.) The temperature unit (from °C to °F
or from °F to °C ) can be changed by:
- Press the AUTO button while
pressing the OFF button on the cli-
mate control unit for 3 seconds
- Go to General settings mode
Unit Temperature in the AVN dis-
play.
Both the temperature unit on the
cluster LCD display and climate con-
trol screen will change.
Odometer
The odometer indicates the total dis-
tance that the vehicle has been driv-
en and should be used to determine
when periodic maintenance should
be performed.

Range
The range is the estimated dis-tance the vehicle can be driven with the remaining fuel.
If the estimated distance is below 1 km (1 mi.), the trip computer will
display "---" as range.
If the hydrogen supply line is empty, the gauge may indicate that the
hydrogen is not in the hydrogentank. Information
 If the vehicle is not on level ground or the battery power has been inter-
rupted, the range function may not
operate correctly.
 The range may differ from the actu- al driving distance as it is only an
estimate of the available driving
range for the vehicle and driving
conditions.
 The range may vary significantly based on driving conditions, driving
habits, and condition of the vehicle.
Gear shift indicator
This indicator displays which gear isselected.
