maintenance HONDA CLARITY FUEL CELL 2018 Owner's Manual (in English)

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 assi st 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;
3WARNING
California Proposition 65 Warning
Operating, servicing and maintaining a
passenger vehicle or off-road vehicle can
expose you to chemicals including engine
exhaust, carbon monoxide, phthalates, and
lead, which are known to the State of
California to cause cancer and birth defects or
other reproductive harm. To minimize
exposure, avoid breathing exhaust, do not
idle the engine except as necessary, service
your vehicle in a well-ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more
information go to
www.P65Warnings.ca.gov/
passenger-vehicle
.
• 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 understanding of the
circumstances in which crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-trivial crash situation
occurs; no data are recorded by the EDR under normal driving
conditions and no personal data (e.g., name, gender, age, and
crash location) are recorded. Howeve r, other parties, such as law
enforcement, could co mbine the EDR data with the type of
personally identifying data routinely acquired during a crash
investigation.
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 requ ired or with the permission of the
vehicle owner.
Service Diagnostic Recorders
This vehicle is equipped with serv ice-related devices that record
information about powertrain perform ance. 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.

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 (P89)
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.

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 regul arly scheduled maintenance.
■Do not leave children unattended in the vehicle
Children 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 which the children and/or another pers on(s) can be injured or killed. Also,
depending on the ambient temperature, th e temperature of the interior may reach
extreme levels, which can re sult in injury or death.
Even if the climate control system is on, never leave children in the vehicle
unattended as the climate control system can shut off at any time.

uuAirbags uAirbag Care
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, the 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 1-800-999-1009.
1 Airbag Care
We recommend against the use of salvaged airbag
system components, including the airbag, tensioners,
sensors, and control unit.
