Quick Reference Guide
Characteristics of Fuel Cell Vehicles
A fuel cell vehicle (FCV) converts hydrogen gas into electricity which is used to power an electric motor. The FC (fuel cell) system comprises
of hydrogen tanks and an FC stack, as well as other components, and requires a constant supply of hydrogen fuel, and proper cooling and
ventilation to generate electricity.
The FC stack is the main power unit which comprises of a series of fuel cells joined together or “stacked” on one another. With in each fuel
cell, a process that combines hydrogen and oxygen results in an electric current which is used to not only power the motor but also charge a
High Voltage battery. This High Voltage battery provides supple mentary power to assist the FC power system when the vehicle is subjected
to heavy acceleration.
Unlike vehicles that use internal combustion engines, FC vehicles emit no harmful emissions such as CO
2 and NOx, and are thus considered
environmentally responsible. The only substance discharged from the tailpipe is water, in the form of both liquid and vapor.
FC Stack
Fuel cell power output may decline faster than usual under the following circumstances:●The vehicle is frequently used in sub-zero temperatures over extended periods of time.●The vehicle is repeatedly left in standby state for extended periods of time.●The FC system is subjected to frequent starting and stopping.●Salt water has permeated the air cleaner element.
u Replace the air cleaner element and clean the surrounding area. For details, consult an authorized Honda Clarity Fuel Cell deal er.
●The vehicle is driven extensively in areas whose air contains high levels of:
Dust
Sulfur (common to hot spring and volcanoes)
Organic solvents, e.g., paints and thinners
Amine-related substances, e.g., ammonia
Chlorinated substances, e.g., salt and snow-melting agents
u Once the vehicle is driven in a normal environment again, fuel cell power output will return over time.
In the following circumstances, power output may be temporarily limited:
●You are repeatedly accelerating and decelerating aggressively.●You are ascending a slope or driving at high altitudes above 6,562 feet (2,000 meters). 2 Driver Information Interface Wa rning and Information Messages (P106)

Maintenance
Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The climate control system is equipped wi th a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1Climate Control System Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.
Refrigerant in your vehicle’ s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.
The air conditioner labe l is found under the hood:

1Dust and Pollen Filter
Using an air freshener may reduce the deodorizing
effect of the dust and pollen filter, and may reduce its
life.
If the airflow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact an authorized Honda Clarity Fuel Cell dealer
for replacement.
The allerfree hi gh retention deodor ization filter
collects pollen and dust, has allergen treatment
ability and reduces exhaus t gas odor that may be
present in the air.

Accessories and Modifications
Accessories
When installing accessories, check the following:
• Do not install accessories on the windsh ield. They can obstruct your view and
delay your reaction to driving conditions.
• Do not install any accessories over areas marked SRS Airbag, on the sides or backs
of the front seats, on front or side pillars, or near the side windows. Accessories
installed in these areas may interfere wi th proper operation of the vehicle’s
airbags or may be propelled into you or another occupant if the airbags deploy.
• Be sure electronic accessories do not overload electrical circuits or interfere with
proper operation of your vehicle.
2 Fuses P. 520
•Before installing any electronic accessory, have the installer contact an authorized
Honda Clarity Fuel Cell dealer for assist ance. If possible, have an authorized
Honda Clarity Fuel Cell dealer inspect the final installation.
1Accessories and Modifications
Honda Genuine accessor ies are recommended to
ensure proper operati on on your vehicle.
3WARNING
Improper accessories or modifications can
affect your vehicle’s handling, stability, and
performance, and cause a crash in which
you can be seriously hurt or killed.
Follow all instructions in this manual
regarding accessories and modifications.
3WARNING
Use of improperly designed, engineered or
manufactured high-voltage battery
assemblies could cause a fire in your
vehicle.
A vehicle fire could result in a crash or
injury.
Only use a genuine Honda high-voltage
battery assembly, or it s equivalent, in your
vehicle.

Modifications
Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Honda parts or accessories that may have a similar
effect.
Even minor modifications to vehicle systems can affect overall vehicle performance.
Always make sure all equipment is prop erly installed and maintained, and do not
make any modification to your vehicle or its systems that might cause your vehicle
to no longer meet federal, state, prov ince, territory, and local regulations.
The on-board diagnostic port (OBD-II/SAE J1962 connector) installed on this vehicle
is intended to be used with automobile system diagnostic devices or with other
devices that Honda has approved. Use of any other type of device may adversely
affect the vehicle’s electronic systems or allow them to be compromised, possibly
resulting in a system malfunction, drained battery, or other unexpected problems.
Do not modify or attempt to repair your vehicle’s high-voltage hybrid power system
or otherwise modify vehicle electrical systems. Disassembling or modifying electrical
equipment can result in a crash or a fire.
If you ever need to replace your vehicle’s high-voltage battery assembly outside of
warranty coverage, we highly recommend that you only use a genuine Honda high-
voltage battery assembly. Genuine Hond a high-voltage battery assemblies are
designed to work with your vehicle’s hybrid power system and have been designed,
engineered and manufactured to avoid ov ercharging situations. Non-genuine high-
voltage battery assemblies may not have be en similarly designed, engineered and
manufactured, and installation of such assemblies could result in overcharging, fires,
loss of power, or other conditions that may increase the likelihood of a crash or
injury.

4.Connect the other end of the second
jumper cable to the power system
mounting bolt as shown. Do not connect
this jumper cable to any other part of the
vehicle.
5. If your vehicle is connected to another
vehicle, start the assisting vehicle’s engine,
and increase its rpm slightly.
6. Attempt to start your vehicle’s power
system. If it starts up slowly, check that the
jumper cables have good metal-to-metal
contact.
