If Hydrogen Gas is Leaking
How to Handle Leaked Hydrogen Gas
When the hydrogen leak indicator comes on,
hydrogen gas is leaking.
When a hydrogen gas leak is detected, the
warning buzzer sounds, and warning
indicator comes on. Follow the message
displayed on the driver information interface
and contact an authorized Honda Clarity Fuel
Cell dealer.
2 Hydrogen Leak Indicator P. 90
Even when the warning indicator does not
come on, if you notice gas leaking noises or
any other malfunction, immediately stop the
vehicle in a safe, well-ventilated place, turn
the power system off, and immediately
contact an authorized Honda Clarity Fuel Cell
dealer.
■When Hydrogen Gas Leak or Other Malfunction is Detected1 How to Handle Leaked Hydrogen Gas
3WARNING
Since hydrogen gas is highly flammable, a
hydrogen gas leak is extremely dangerous
as the leaked gas, which is dispersed into
the atmosphere, can ignite, resulting in a
fire in which you or someone else can be
serious injured or killed. Keep flammable
materials and liquids away from the vehicle
at all times, especially if a hydrogen gas
leak is detected.
In the case of a hydrogen gas leak, a buzzer
will sound and the hydrogen gas leak
indicator will come on. If you are driving
the vehicle, sto p in a safe, well-ventilated
place. Then turn th e power mode to OFF
and contact an author ized Honda Clarity
Fuel Cell dealer at once. You should also
display signs warning of the danger and be
aware of and keep aw ay anything that
could ignite the gas.
The system is designed so that in the event
that the vehicle catche s fire, the gas inside
the tanks will be released through the tank
valves, thereby ensuring that pressure (due
to heat from the fire) within the tanks does
not build up.
