California Proposition 65 Warning
Event Data Recorders
This vehicle is equipped with an event data recorder (EDR).
The main purpose of an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deployment or hitting a
road obstacle, data that will assist in understanding how a vehicle’s
systems performed. The EDR is designed to record data related
to vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or le ss. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were
buckled/fastened;
• How far (if at all) the driver was depressing the accelerator
and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understandi
ng of the
ci

rcumstances in which crashes and injuries occur. NOTE: EDR
data
are recorded

by your vehicle only if a non-trivial crash
situation
oc

curs; no data are recorded by the EDR under normal driving
conditions and no personal data (e.g., name, gender, age, an
d
crash location) are

recorded. However, other parties, such as
law
enforcem

ent, could combine the EDR data with the
type of
perso

nally identifying data routinely acquired during a cr
ash
investig

ation.
WARNING: This product contains or emits
chemicals known to the state of California to cause
cancer and birth defects or other reproductive
harm.
To read data recorded by an ED R, special equipment is required,
and access to the vehicle or the EDR is needed. In addition to the
vehicle manufacturer, other parties, such as law enforcement, that
have the special equipment, can re ad the information if they have
access to the vehicle or the EDR.
The data belongs to the vehicle ow ner and may not be accessed by
anyone else except as legally requir ed or with the permission of the
vehicle owner.
Service Diagnostic Recorders
This vehicle is equipped with se rvice-related devices that record
information about powertrain perfo rmance. The data can be used
to verify emissions law requirem ents and/or help technicians
diagnose and solve service problems. It may also be combined with
data from other sources for res earch purposes, but it remains
confidential. Some diagnostic and maintenance information is
uploaded to Honda upon vehicle start up.
California Perchlorate Contamination Prevention Act
The airbags, seat belt tensioners , and CR type batteries in this
vehicle may contain perchlorate ma terials - special handling may
apply. See www.dtsc.ca.gov/hazardouswaste/perchlorate/
As you read this manual, you will find information that is preceded
by a symbol. This information is intended to help you avoid
damage to your vehicle, othe r property, or the environment.

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.

Quick Reference Guide
Ion Exchanger
An ion exchanger is installed in the fluid lines for the fuel cell in order to maintain the
insulation properties of the fuel cell insulating fluid (FC insulating fluid).
If the message Service Due Soon A appears on the driver information interface, ion
exchange filter replacement is necessary. Be sure to consult an authorized Honda Clarity
Fuel Cell dealer. 2 Indicators (P87)
Exhaust Pipe
Water is expelled from the tail pipe while the vehicle is running or while the High Voltage
battery is being charged. This also happens af ter the vehicle has been running or when you
shut down the FC system by setting the power mode to OFF. If you stand to the left rear of
the vehicle, you may be sprayed by this waste water.
Never drink water expelled from the pipe. Though this water is harmless, it is not suitable
for drinking.
While the vehicle is parked during cold temperatures, the FC system may automatically turn
on and discharge water from the ex haust pipe. If this water is discharged as a vapor, it may
appear as a white mist. This, however, is not indicative of a problem.
Do not obstruct or block the exhaust pi pe as the FC system may stop working.
Maintenance, Repair, and Disposal
Always consult an authorized Honda Clarity Fuel Cell dealer regarding maintenance, repair,
and disposal.
Fuel cells and High Voltage batteries that have been removed from disposed vehicles are
collected through authorized Honda Clarity Fuel Cell dealers. Do not dispose of those
batteries yourself.
WARNING
Do not directly touch any water emissions
from the exhaust pipe.
Water created during FC power generation
is discharged from the exhaust pipe in the
form of either liquid (water) or gas (steam).
Directly touching this water may cause
burns.

Safe Driving
Airbag Care
You do not need to, and should not, perform any maintenance on or replace any
airbag system components yourself. However, you should have your vehicle
inspected by an authorized Honda Clarity Fuel Cell dealer in the following situations:
■When the airbags have deployed
If an airbag has inflated, th e control unit and other related parts must be replaced.
Similarly, once an automatic seat belt te nsioner has been activated, it must be
replaced.
■When the vehicle has been in a moderate-to-severe collision
Even if the airbags did not inflate, have your authorized Honda Clarity Fuel Cell
dealer inspect the following: th e driver’s seat position sensor, weight sensors in the
passenger’s seat, front seat belt tensioners , and each seat belt that was worn during
the crash.
■Do not remove or modify a front seat without consulting an authorized
Honda Clarity Fu el Cell dealer
This would likely disable or affect the proper operation of the driver’s seat position
sensor or the weight sensors in the passenge r’s seat. If it is necessary to remove or
modify a front seat to accommodate a person with disabilities, contact an
authorized Honda Clarity Fuel Cell dealer , or for U.S. vehicles, American Honda
Automobile Customer Service at 1-800-99 9-1009 and for Canadian vehicles, Honda
Canada Customer Relations at 1-888-9-HONDA-9.
1 Airbag Care
We recommend against the use of salvaged airbag
system components, including the airbag, tensioners,
sensors, and control unit.
