Quick Reference Guide
Hydrogen Leak Detection System
When the power mode is turned to ON, the hydrogen leak detection system is activated. If a
hydrogen gas leak is detected by the hydrogen detector, the hydrogen leak indicator will
come on.
2 Hydrogen Leak Indicator (P92)
Hydrogen Supply/High Voltage Shut-off System
If the FC system is on and the vehicle is involv ed in a crash, depending on the severity of the
impact, the shut-off system will cut off the supply of hydrogen and electricity. In this case, it
is not possible to restart the vehicle.
To restart the FC system, consult an authorized Honda Clarity Fuel Cell dealer.
WARNING
Do not block the hydrogen ventilation
ducts.
The hydrogen tanks, FC stack, and
hydrogen supply components have
ventilation ducts to allow any leaked
hydrogen to escape into the atmosphere. If
the opening of a duct is blocked with snow,
leaves, etc., and a hydrogen leak occurs, the
leaked gas can make its way into the motor
room, where it can ignite, resulting in a fire
or explosion.
Make sure the ducts are free of any
obstructions before activating the power
system.
Do not remove or disassemble a hydrogen
duct: Doing so can lead to a fire or
explosion if a hydrogen gas leak occurs.

Quick Reference Guide
In Case of a Crash
●If a vehicle fire occurs, leaked hydrogen gas may ignite. Stay far away from the vehicle
and call the local fire department.
To extinguish a vehicle fire, use a large amount of water, dry chemical fire extinguisher
(Class A, B, or C), or carbon dioxide fire extinguisher. With an inadequate amount of
water, a fire cannot be put out completely. Never attempt to extinguish a vehicle fire
with a small amount of water.
●If your vehicle needs to be towed, make sure it is done with all the wheels lifted using the
flat bed equipment. If the front wheels are touching the ground, the rotating tires will
force the electric motor to spin, which in turn, may damage the power system,
transmission, etc.
WARNING
If the body of the vehicle is seriously
damaged or deformed in a crash, hydrogen
gas may leak out from the vehicle. Keep
flammable sources, such as a lit cigarette or
warning flares, away from the vehicle. 2If Hydrogen Gas is Leaking (P513)
Also, high voltage parts and/or the cables
(orange) connecting them may be exposed
as a result of a crash. Stay clear of these
parts as you may be electrocuted.
If the vehicle catches fire, leaked hydrogen
gas may ignite. Stay far away from the
vehicle and report to the fire department
that a vehicle containing hydrogen tanks is
on fire.
The system is designed so that in the event
that the vehicle catches fire, the gas inside
the tanks will be released through the tank
valves, thereby ensuring that pressure
within the tanks does not build up. This gas
is released toward the rear of the vehicle in
a downward direction. Do not attempt to
extinguish the fire from behind the vehicle
as the exiting gas may ignite into a flame.

vision while driving. If frozen solid , remove ice once it has softened.
u When removing ice from around the wheel s, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.

NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the power syst em can ignite flammable
materials left under the hood, causing a fire. If you’ve
parked your vehicle for an extended period, inspect
and remove any debris that may have collected, such
as dried grass and leaves th at have fallen or have
been carried in for use as a nest by a small animal.
Also check under the hood fo r leftover flammable
materials after you or so meone else has performed
maintenance on your vehicle.
