1. Does a Hydrogen Fuel Cell Electric Vehicle (FCEV) have similar performance
to standard, non-electric vehicles?FCEV performance characteristics are generally equivalent to stan-
dard vehicles, but with better noise control.
2. If water floods the fuel cell power modulecompartment, due to heavy rain or flood-
ing for example, will it have any effect on
the vehicle?
Every component housed in the fuel cell power module compart-
ment is designed to be waterproof through evaluation which meets
the IP69K standard, so you don't have to worry about any potential
faults or safety problems if water contacts the fuel cell. However, if
the vehicle is fully flooded, have the vehicle checked by an author-
ized HYUNDAI dealer.
3. When starting or stopping the vehicle,there's a noise. Is this noise cause for
concern?
The sound you hear is normal. The noise emanates from the blower
motor starting up to remove any residual water vapor in the fuel cellsystem. Also, when you turn on the vehicle you may hear a brief oper-
ation sound from the hydrogen storage system which is located on the
back of the vehicle. This is a normal sound which is occurred when the
system tries to balance the pressure between the hydrogen tanks.
4. Is there a possibility that extremely cold weather can prevent vehicle startup?
In most instances, the vehicle can get startup in cold weather with-
out any problems. However, the vehicle may not start if the vehicle is
parked with the ignition off for over a week in cold temperatures. In
this case, turn on the vehicle 2-3 times repeatedly. If you will not be
turning on the ignition for more than a week in cold weather, it is
recommended that you park the vehicle inside a building, if possible. Notice)
In particular, make sure to park the vehicle indoor when the temper-
ature is below -30°C. If the vehicle is parked outside for over 12
hours under such weather fuel cell components may be damaged.
Also, avoid driving under such weather to prevent damaging the fuel
cell components.

Cluster /
Warning Lamp
(9 items)
23. What shall I do if the hydrogen gas leak warning light turns on on the cluster?
(Red)If the hydrogen gas leak warning light turns on during "READY" sta-
tus or in driving mode, this indicates a hydrogen gas leak inside the
vehicle. DO NOT lose your composure. Park your vehicle and turn
OFF the vehicle. Then, contact an authorized HYUNDAI dealer for
service.
24. Can I keep driving the vehicle even ifthe hydrogen gas leak warning light
turns on on the cluster?
(Red)The fuel cell stops working if hydrogen is no longer available. However,
the FCEV can run for an additional distance (About 3 km (2 miles)) in
EV mode where the vehicle runs only on battery power. Mileage in EV
mode can vary depending on the "state of charge" (SOC) of the high
voltage battery, so move your vehicle to the nearest shoulder on the
road. Then, contact an authorized HYUNDAI dealer for service.
25. While driving to a service center afterthe hydrogen gas leak warning light
turns on on the cluster, is it possible
that the vehicle catch fire if there is
something nearby to ignite the leaking
gas (cigarette butt, etc.)?
(Red)
As soon as the hydrogen gas leak warning light appears, the fuel
cell operation is disabled immediately to cut the supply of hydrogen.
This prevents the possibility of a fire occurring.
26. What should I do if a power down warn-ing light turns on?If the power down warning light turns on during "READY" status or
in driving mode, power supply to the fuel cell system is cut off. If the
warning light turns on repeatedly when restarting the vehicle after
parking your car on the safe place, please contact an authorized
HYUNDAI dealer for service.
