age detection sensor. In this case,
have the vehicle checked by an
authorized HYUNDAI dealer.
Refueling…
This warning message is displayed
while refueling the vehicle. Do not
turn on the vehicle and wait until the
refueling is complete.Check fuel door sensor
This warning message is displayed
when there is a malfunction with the
sensor located below the fueling inlet
which is used for communicating
with the fueling station. Check and
remove if there is any foreign sub-
stance around the fueling inlet.
If this message is still displayed after
the foreign substance is removed,
have the vehicle checked by an
authorized HYUNDAI dealer.
Open fuel door after turning
vehicle Off
This warning message is displayed

cycles exceeded
This warning message is displayed
when the number of times refueling
the vehicle exceeds the predefined
number (4,995 times). The fuel cell
system stops operation for safety
even if the vehicle is refueled enough
and when there is no problem with
the vehicle. In this case, have the
hydrogen storage system replaced
by an authorized HYUNDAI dealer.
Power limited due to fuel cell
system error
This warning message is displayed
when there is a malfunction with the
fuel cell system and the power sup-
ply to the fuel cell system is limited.
If the warning light stays on when in
"Ready ( )" state or while driving

9. Can driving on test roads or over speed
bumps damage the high voltage battery
and hydrogen tank?
The high voltage battery and hydrogen tank are unlikely to be damaged
under normal driving conditions. However, if the system begins to mal-
function due to a direct and serious vehicular impact, you are informed
of those system errors via warning lights on and the LCD display.

10. A water-like liquid is being discharged
from the muffler and bottom of the vehi-
cle. Is it harmful to humans?
Water or vapor discharged is generated from electrochemical reac-
tions in the fuel cell stack, and is not harmful to humans. However,
liquids generated from the reactions can be somewhat acidic, so DO
NOT touch or ingest the liquid!
Also, the water discharged when parking the vehicle indoor may
make a puddle on the floor. Be careful as such puddle can freeze
and result in accident during winter.

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 burn
out 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 cell
system 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, we recommend that you contact
an authorized HYUNDAI dealer for service.
42. Is the recharge performance of the high
voltage 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.
