System
(7 items)36. How should I refuel the tank with hydro- gen gas? And what should I take care of?
* Close the fuel cap and fuel filler door firmly.
* The gas tank may not be fully filled depending on the conditions ofthe hydrogen station.
* Carefully read any precautions about refueling at hydrogen gas stations.
* Be careful not to cause static electricity when touching the fuel filler with your hand. (To avoid static electricity, be sure to touch
your bare hand on something metallic as far from the fuel filler as
possible.)
* DO NOT get out of, or go into, your car while the gas tank is being refueled.
* DO NOT use any mobile device. Fire may occur due to electric current / radio wave from the mobile device.
* Make sure that the fuel cell system stops working before refueling the gas tank.
* DO NOT smoke a cigarette or strike a lighter while refueling the gas tank.
* If you need assistance with refueling the gas tank after completely consuming all the available fuel in the vehicle, please contact an
authorized HYUNDAI dealer.

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 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.
