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

.
• 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
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, hydrogen reacts with oxygen to create an electric current whic h is used to not only power the motor but also charge a High Voltage 
battery. This High Voltage battery provides supplementary 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 friendly. The only substa nce discharged from the tailpipe is water,  in the form of both liquid and vapor.
FC Stack
Fuel cell power output may decline faster th an 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 stand by 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.
● 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 substa nces, 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).
