5. Why is there an engine noise at low speeds, even though there is no engine?The noise is generated from the air compressor and cooling pump
working to supply air to the fuel cell or it's from Virtual Engine
Sound System (VESS).
6. When turning on and off the vehicle incold weather, there's a loud noise. Is this
noise cause for concern?
When you turn on the vehicle or turn off the vehicle in cold weather,
the air compressor removes the generated water inside the fuel cell
system and the noise is generated during this process, which is nor-
mal. In this case, certain amount of water may drain through the
vehicle bottom and exhaust pipe.
7. Why does a noise emanate when thevehicle moves in reverse?
Normally, the noise is a result of the Virtual Engine Sound System
(VESS) working when the FCEV runs at low velocity (1~12 mph
(1~20 km/h)) after shifting to D or N. However, when shifting to R,
the VESS operates immediately, regardless of vehicle speed. In
addition, a separate warning chime will sound to have the pedestri-
an aware of the approaching vehicle.
8. The FCEV is equipped with a reductiongear but no transmission. What makes it
different from standard vehicles?
The transmission of standard vehicles delivers power as conditions
require via multiple transmission gears. However, the reduction gear
of the FCEV is designed to deliver power by reducing the motor's
RPM as operating conditions dictate, or to move backwards by
reversing the rotational direction of the shaft.

11. Can I wash my FCEV with pressurized water? What if water flows into the fuel
cell power module compartment?
Every component housed in the fuel cell power module compart-
ment is designed to be waterproof like those found in standard vehi-
cles. Therefore, a short circuit of the FCEV cannot happen while
washing the car. However, your FCEV works by utilizing high-voltage
electric power, so it is recommended that you avoid high-pressure car
washes. If the insulation resistance of the FCEV deteriorates due to
car wash, a High voltage warning light may turn on the cluster.

12. When washing the fuel cell power mod-ule compartment, is there any potential
risk of electric shock resulting from a
high-voltage short circuit?The FCEV is designed to be a waterproof structure, but please
avoid washing the inside of the compartment if possible. Because
there are many high voltage parts in the power module compart-
ment.
13. Can I wash the bottom of the vehicle? Ifyes, what should I be aware of?The FCEV is designed to be a waterproof structure, but please
avoid washing the botttom of the vehicle if possible. Because there
are high voltage cables in the under cover.
14. Can driving with a tire chain affect thedrive motor?Driving with a tire chain causes no direct damage to the drive motor.
15. How should I jump start the vehicle?
Try charging it by pressing the "12V BATT RESET" button first.
Refer to the "If the 12 volt battery is discharged" in this guide book.
It it doesn't work, refer to the "Jump starting" in the Owner's manual
chapter 6.

19. What are the do-it-yourself (DIY) main- tenance items for the FCEV?
DIY Check: Device cooling coolant, Stack cooling coolant, Brake
Fluid, Tire and Wheels
DIY Maintenance: Washer fluid, Air cleaner, Climate control air filter,
Wiper blades, Fuse, Light bulb
20. What should I be aware of when doingDIY maintenance work?Be careful not to touch the high-voltage cable (orange color),
coolant, and ion filter.
21. Tell me what the potential effects are ofparking long-term in a cold area (-4 °F
(-20 °C)) for the FCEV, and whether or
not the vehicle can startup under such
conditions.In most instances, the vehicle can get startup in cold weather with-
out any problems. However, the vehicle may not start if it is parked
with the power off for over a week in cold temperatures. In this case,
If you will not be turning on the vehicle for more than a week in cold
weather, it is recommended that you park the vehicle inside a build-
ing, if possible.
22. What parts must I not touch withhands? For example, high-voltage
cable, ion filter, etc.?
High-voltage cable (orange color), ion filter, parts with a high voltage
warning sticker.
Also, never touch the hydrogen storage system under the liftgate,
the hydrogen supply pipe under the vehicle and the hydrogen supply
system components on the right side (based on the driver’s position)
of the hood.

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 2 miles (3 km)) 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.

27. What should I do if the service warning light turns on?If the service warning light turns on during "READY" status or in driv-
ing mode, it may indicate a malfunction in operation with any fuel cell
system. Please contact an authorized HYUNDAI dealer for service.
28. What should I do if the master warninglight turns on?If the service warning light turns on when there is a malfuction in
operation in any of the vehicle systems. Please look at the LCD dis-
play for details and contact an authorized HYUNDAI dealer for service
if needed.
29. How much farther (roughly) can I drivemy FCEV when the fuel warning light
turns on? (Remaining mileage)You can continue driving for an additional 40~55 miles (70~90 km).
It may depend on driving mode.
30. When restarting the vehicle, the " "indicator turns on on the cluster. What
does this mean?It means that the fuel cell system is working in good order and your
car is ready to drive.
31. Why does the vehicle’s hydrogen tankhave a life expectancy?
The hydrogen tank is frequently refueled with the high pressure
hydrogen gas and the number of times refueling the vehicle is limit-
ed to 5,000 times (or 15 years). The hydrogen storage system
counts the number of times the vehicle is refueled and turns on the
warning light when the vehicle is refueled for over 4,995 times.
Every time the vehicle is turned on the warning message "Replace
hydrogen tank. Maximum number of refill cycles exceeded" is dis-
played on the cluster. The vehicle can be driven about 1-3 million
kilometers until the vehicle is refueled 5,000 times, meaning that the
hydrogen tank is used semi-permanently under common driving
condition.

39. What happens if hydrogen gas leaks from the fuel cell stack?
(Red)If hydrogen gas leaks beyond what's tolerable from the fuel cell stack,
a hydrogen sensor installed in the system detects the leak and in
response, turns ON the hydrogen gas leak warning light in the cluster.
40. Can the fuel cell stack explode or burnout due to overheating?The fuel cell stack passed a high temperature test and is deemed
safe, so it is unlikely to explode.
41. Which symptoms occur if the fuel cellsystem malfunctions?
If the fuel cell system malfunctions, warning lights specific to the
actual problem appear on the LCD display. When this happens, the
vehicle speed may be limited, or the fuel cell system may shut
down. DO NOT lose your composure if this happens. Park your vehi-
cle and turn OFF the vehicle. Then, contact an authorized HYUNDAI
dealer for service.
42. Is the recharge performance of the highvoltage battery reduced depending on
its length of use? Like any vehicle component, the high voltage battery will decrease
in performance as it ages over time. However, the high voltage bat-
tery of the FCEV is durable enough to work at peak performance
beyond the warranty period.
