43. Is there a risk of electric shock from the high-voltage parts in the event of a colli- sion or accident?
The FCEV is designed to detect impact events during a collision or
accident so that the hydrogen gas supply is immediately cutoff. Also,
the high-voltage relay is activated to cutoff the supply of electric power
to the fuel cell stack and high-voltage battery. Moreover, the FCEV
satisfies international electrical safety standards for collisions and
accidents.
44. Should I take any special safety precau-tions in the event of a collision or acci- dent?
Despite the uniqueness of the hydrogen FCEV, you do not have to
take any special safety precautions in the event of a minor collision or
accident. In the event of a minor accident, turn off the vehicle to cutoff
the supply of electric power and hydrogen gas. Also, the FCEV is
equipped with collision sensors at the front and rear of the vehicle so
those sensors are activated during an actual collision to automatically
cutoff the supply of power and hydrogen to ensure driver and passen-
ger safety. For other situations, follow the same procedures as you
would with a standard vehicle. Depending on the severity of the colli-
sion or accident, take appropriate measures.
45. Is a high-voltage battery designed toensure occupant safety? Can it explode from a collision?Our battery packs are designed to prevent any explosion due to
physical impact or damage, and they fully satisfy international safety
standards.

46. Is a hydrogen tank designed to ensure occupant safety? Can it explode from a collision?The hydrogen tank is designed to prevent any risk of explosion. It is
completely safe.
47. How should the FCEV be towed, andwhat precautions should be taken?
The FCEV can be towed in the same manner as standard vehicles. If
you need emergency towing, it is recommended that you contact an
authorized HYUNDAI dealer. To avoid damage to the vehicle, you
need to follow proper pulling and towing procedures. The FCEV is
equipped with a front wheel drive (FWD) motor, so use a flatbed or
wheel dolly to tow the vehicle. If the front wheels touch the road sur-
face while being towed, they will rotate and this can cause the FWD
motor to generate electricity. This can cause unwanted failure of the
FCEV.

Fire (5 items)
48. What should I do if the FCEV catches fire?
1. stop driving the car. Move the shift to P (Park) , then step on thebrake to turn OFF the vehicle. The fuel cell stack is shut down,
which cuts off the supply of hydrogen fuel.
2. If possible, open the windows to ventilate the air.
3. If the fire is small enough to get under your own control, use the fire extinguisher to put it out.
If the fire is much larger, get out of your car and contact the local
fire station to report your FECV is on fire. DO NOT get close to your
car before the fire is completely extinguished.
49. In case of vehicle fire, should I use the fire extinguisher? Can I use water to
extinguish the fire?
In the event your FCEV catches fire with the power system OFF, the
power source of the high-voltage system is cut off, so you are unlikely
to get shocked while you put out the fire using water. (Even when the
vehicle is submerged in water, there is no risk of getting shocked.)
However, if your car catches fire with the ignition ON, you MUST use
the fire extinguisher. Any attempt to extinguish the fire with water may
cause electric shock.
50. What kind of fire extinguisher should Iuse?It is recommended that you use a dedicated fire extinguisher (CO2)
for an electrical fire of the high-voltage system.
51. Can the hydrogen tank explode if itoverheats in very hot weather?The hydrogen tank passed a high temperature test and is deemed
safe, so it is unlikely to explode.
52. In case of vehicle fire, is it possible that
the hydrogen tank will explode?
In case of vehicle fire, a heat-sensitive safety valve is activated to
exhaust the hydrogen gas downward from the tank by force.
Therefore, the hydrogen tank is unlikely to explode. However, addi-
tional flames can flare up from the forced exhaustion of the gas, so
please evacuate to a safe place far away from the vehicle.
