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.

VSA® On and Off (P 416)
●The Vehicle Stability AssistTM (VSA ®)
system helps stabilize the vehicle during
cornering and helps maintain traction
while accelerating on loose or slippery
road surfaces.
●VSA ® comes on automatically every time
you turn on the power system.
●To partially disable or fully restore VSA ®
function, press and ho ld the button until
you hear a beep.
CMBSTM On and Off
(P 438)
●When a possible frontal collision is likely
unavoidable, the CMBSTM can help you to
reduce the vehicle speed and the severity
of the collision.
●To turn the CMBSTM on or off, press and
hold the button until you hear a beep.
Tire Pressure Monitoring
System (TPMS)
(P 418)
●Detects a change in tire conditions and
overall dimensions due to decrease in tire
pressures.
●The TPMS is turned on automatically
every time you turn on the power system.
●A calibration procedure must be
performed when certain conditions arise.
Refueling (P 447)
aSet the power mode
to OFF.
bPress the hydrogen
fuel lid release
button on the
driver’s door to open
the fuel lid.
cRemove the dust cap
inside the hydrogen
fuel lid.
dStart refueling.
Fuel requirement: Compressed hydrogen gas
Hydrogen supply pressure: 70 MP a (10,153 psig) (at 59°F [15°C])
Hydrogen filling amount
*1: Approximately 11 lbs (5 kg) (at 70 MPa)
Hydrogen tanks capacity: 37.3 US gal (141.3 L) (at 70 MPa [10,153 psig])
*1:
A measured value when refueled at a hydrogen station with 70 MPa (10,153
psig) of supply pressure compliant with the SAE (J2601) fueling protocol.
Hydrogen Filling Station: To completely fi ll the hydrogen tank, you need to use a
hydrogen filling station that has an H70 di spenser, which is capable of supplying
pressures of up to 10,153 psig (70 MPa).
Refueling the vehicle is only possible if the pressure inside the hydrogen tank of
the vehicle does not exceed the supp ly pressure of the filling station.
If you use an H35 dispenser, you will be able to fill only half of the tank.

uuFor Safe Driving uImportant Safety Precautions
Safe Driving
■Pay appropriate attention to the task of driving safely
Engaging in cell phone conversation or other activities that keep you from paying
close attention to the road, other vehicles , and pedestrians could lead to a crash.
Remember, situations can change quickly, and only you can decide when it is safe to
divert some attention away from driving.
■Control your speed
Excessive speed is a major factor in crash injuries and deaths. Generally, the higher
the speed, the greater the risk, but serious injuries can also occur at lower speeds.
Never drive faster than is safe for current conditions, regardless of the maximum
speed posted.
■Keep your vehicle in safe condition
Having a tire blowout or a mechanical failure can be extremely hazardous.
To reduce the possibility of such problems, check your tire pressures and condition
frequently, and perform all re gularly scheduled maintenance.
■Do not leave children unattended in the vehicle
Children, pets and people needing assistan ce left unattended in the vehicle may be
injured if they activate one or more of the vehicle controls. They may also cause the
vehicle to move, resulting in a crash in wh ich they and/or another person(s) can be
injured or killed. Also, depending on the am bient temperature, the temperature of
the interior may reach extreme levels, which ca n result in harm or death. Even if the
climate control system is on, never leave them in the vehicle unattended as the
climate control system can shut off at any time.

Driving
Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on th e windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
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.
u Check air pressures, and check for damage and excessive wear.
2Checking and Maintaining Tires P. 470
•Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
■Exterior Checks1Exterior Checks
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.

uuWhen Driving uVehicle Stability AssistTM (VSA ®), aka Electronic Stability Control (ESC), System
Continued
Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating motor out put and selectively applying the brakes.
When VSA ® activates, you may notice that the
motor does not respond to the accelerator.
You may also notice some noise from the
hydraulic brake system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability AssistTM (VSA® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by an authorized
Honda Clarity Fuel Ce ll dealer immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and alwa ys leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.
