Hydrogen Gas Leak
If a hydrogen gas leak is suspected, follow the recommended actions listed in the
instructions of this owner’s manual. 2 If Hydrogen Gas is Leaking (P487)
WARNING
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, stop in a safe, well-ventilated
place. Then turn the power mode to OFF
and contact an authorized Honda Clarity
Fuel Cell dealer at once. You should also
display signs warning of the danger and be
aware of and keep away anything that
could ignite the gas.
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 (due
to heat from the fire) 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.

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 complaint wi th 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. Set the power mode to ON.
2. Select .
3. Select Settings .
4. Select Vehicle .
5. Select TPMS Calibration .
6. Select Cancel or Calibrate.
u When the calibration is complete, the

• If the Calibration Failed To Start.
message appears, repeat steps 4-6.
• The calibration pr ocess finishes
automatically.1 TPMS Calibration
•The calibration process requires approximately 30
minutes of cumulative dr iving at speeds between
30-65 mph (48-105 km/h).
•During this period, if the power system is turned on
and the vehicle is not moved within 45 seconds,
you may notice the low tire pressure/TPMS
indicator comes on briefl y. This is normal and
indicates that the calibr ation process is not yet
complete.
If snow chains are instal led, remove them before
calibrating the TPMS.
If the low tire pressure/TPMS indicator comes on even
when the properly inflated specified regular tires are
installed, have your vehicl e checked by an authorized
Honda Clarity Fuel Cell dealer.
We recommend that the tires be replaced with the
same brand, model, and size as the originals. Ask an
authorized Honda Clarity Fuel Cell dealer for details.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Continued
Driving
Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufa cturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diff erent size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflat ion pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-inf lated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pu mp the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
You may hear an operating noise when the ABS is working. Keep holding the pedal
firmly down. On dry pavement, you will ne ed to press on the brake pedal very hard
before the ABS activates. Ho wever, you may feel the ABS activate immediately if you
are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have your
vehicle checked by an authorized Honda Clarity Fuel
Cell dealer immediately.
The ABS does not reduce the ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
•When tire chains are installed.
The following may be observed with the ABS system:
•Motor sounds coming from the motor
compartment when the brakes are applied, or
when system checks are being performed after the
power system has been turned on and while
vehicle is accelerates.
•Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.

Compressed hydrogen gas
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.

Fuel Economy
Improving Fuel Economy
Achieving fuel economy is dependent on several factors, including driving
conditions, load weight, standby time, driving habits, and vehicle condition.
Depending on these and other factors, you may not achieve the rated fuel economy
of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accord ance with the messages displayed on the
driver information interface.
• Maintain the specified tire pressure.
• Do not load the vehicle with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.
