Quick Reference Guide
High Voltage Components, High Voltage Cables and High Temperature
Components
Fuel cell vehicles have high voltage components (about 500 V maximum) such as the FC stack, FCVCU, High Voltage battery, power control
unit, high voltage cables (identified by their orange covers), el ectric motor, and high temperature parts such as the radiator. Labels with
handling warnings are attached to these components.
WARNING
This vehicle has high voltage circuits and
parts. Failure to observe the following
precautions can result in burns or electric
shock.
●Do not remove, disassemble, or replace
the high voltage parts, cables (orange) or
their connectors.
●Never touch the High Voltage battery
service plugs.
In an emergency or during maintenance or
repair, the service plugs are removed to cut
off the electric flow from the battery. These
plugs are in contact with the battery and
can cause severe electric shock if not
handled properly.
Only a qualified technician should handle
any electrical equipment. For inspection
and repair, consult an authorized Honda
Clarity Fuel Cell dealer.

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 (P90)
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.

VSA® On and Off (P 414)
●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 436)
●When a possible 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 416)
●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.

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.

1 Refueling
NOTICE
If improper hydrogen gas is us ed, the FC stack will be
damaged. Always refuel at authorized hydrogen
filling stations.
2 Refer to the Navigation System Manual
Hydrogen gas is colorless, odorless, very light and
flammable. Also, its burni ng flame is difficult to
detect by sight.
3WARNING
When refueling hydrogen gas, keep
sources of fire, such as a lit cigarette, away
from the vehicle. As hydrogen gas is highly
flammable, it may caus e a fire or explosion.
Be sure to turn the po wer system to OFF to
stop the FC stack operation.

Maintenance
Inverter Coolant
This coolant is premixed with 50% an tifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the inverter cool ant level every time you refuel. Check
the reserve tank. Add the in verter coolant accordingly.
1. Make sure the motor and radiator are cool.
2. Check the amount of coolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Ho nda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Inverter Coolant
NOTICE
Genuine Honda inverter coolant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout –31°F (–35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult an authorized
Honda Clarity Fuel Ce ll dealer for details.
If Honda antifreeze /coolant is not available, you may
use another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended fo r aluminum motors.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda anti freeze/coolant as soon as
possible.
3WARNING
Removing the expansion tank cap while the
motor is hot can cause the coolant to spray
out, seriously scalding you.
Always let the motor and radiator cool
down before removing the expansion tank
cap.

u The compressor starts injecting sealant
and air into the tire.
u When the sealant injection is complete,
continue to add air.
8. After the air pressure reaches 36 psi (250
kPa), turn off the kit.
u To check the pressure, occasionally turn
off the compressor, and read the
gauge.
9. Unplug the power plug from the accessory

Pressure Gauge1Injecting Sealant and Air
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begin to rise again as the
tire is inflated with air. This is normal. To accurately
measure the air pressure usin g the gauge, turn the air
compressor off only after the sealant injection is
complete.
If the required air pressure is not reached within 10
minutes, the tire may be too severely damaged for
the kit to provide the necessa ry seal, and your vehicle
will need to be towed.
See an authorized Honda Clar ity Fuel Cell dealer for a
replacement sealant bottle an d proper disposal of an
empty bottle.

■Next thing to do
Inspect the coolant level, and check the
cooling system components for leaks.u If the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
u If there is no coolan t in the reserve tank,
check that the radiator is cool. Cover the

and open the cap. If necessary, add
coolant up to the base of the filler neck,
and put the cap back on.
■Last thing to do
Turn the power system on, if the message Power System Problem. Stop Driving
