California Proposition 65 Warning

WARNING: This product contains or emits chemicals known to the state of California to cause cancer and birth defects or other reproductive harm.

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 less. 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 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. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.

To read data recorded by an EDR, 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 read the information if they have access to the vehicle or the EDR.

The data belongs to the vehicle owner and may not be accessed by anyone else except as legally required or with the permission of the vehicle owner.

Service Diagnostic Recorders

This vehicle is equipped with service-related devices that record information about powertrain performance. The data can be used to verify emissions law requirements and/or help technicians diagnose and solve service problems. It may also be combined with data from other sources for research 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 materials - special handling may apply. See www.dtsc.ca.gov/hazardouswaste/perchlorate/

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. Within each fuel cell, hydrogen reacts with oxygen to create an electric current which 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 CO2 and NOx, and are thus considered environmentally friendly. 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.

uReplace 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 substances, e.g., ammonia

Chlorinated substances, e.g., salt and snow-melting agents

uOnce 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).

Fuel Cell Power System

The fuel cell power system regulates the fuel cells to maintain efficient power generation in various driving conditions. The power system is unique to fuel cell vehicles and differs to that of conventional internal combustion vehicles or electric vehicles in the following ways:

Depending on circumstances, the system may need to adjust the condition of the fuel cells before shutting down; therefore, the power system may continue to operate even after the power mode is set to OFF.

In cold temperatures, the power system may take more time to start or stop than usual as the fuel cells need to be conditioned before they can generate power.

Hydrogen Tanks

Outline

The hydrogen tanks are the storage containers that house the compressed hydrogen gas.

Inspection

Owners of fuel cell vehicles are required by law to have these tanks inspected periodically. Filling a hydrogen tank with compressed hydrogen gas is prohibited by law if the tank has not passed inspection or if the tank has expired.

The hydrogen tanks are affixed with an expiration date. This date is also affixed to the underside of the hood and the hydrogen fuel lid. If a tank has expired, replace it immediately.

Disposal

Disposal of hydrogen tanks or hydrogen tank valves must be done in accordance with the pertinent rules and regulations of the state or region within which the tanks or valves are to be disposed of. For details, consult an authorized Honda Clarity Fuel Cell dealer.

Theft

If your fuel cell vehicle is stolen, be sure to inform the police that the vehicle is equipped with tanks filled with compressed hydrogen gas.

Refueling

Fuel cell vehicles need hydrogen to run. Refuel with compressed hydrogen gas at an authorized hydrogen filling station.

10

Sounds Unique to the Fuel Cell Vehicle

When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particularly when you first turn on the power system, while driving, and just after parking. Some of these sounds are unique to this vehicle’s powertrain, fuel, and climate control systems; others are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a vehicle of this design. These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any new or unusual noise should one develop.

Certain sounds associated with your vehicle may be caused by:

● Pressurized intake air being released through the rear of the vehicle.

uThis can happen if the accelerator is released suddenly when the vehicle is under a heavy load, such as when climbing a hill.

The power system warming up.

uThis sound is particularly loud when temperatures are extremely low (below –4°F [–20°C]).

WARNING

Never leave the fuel cell vehicle in standby state in an enclosed area that has limited ventilation as there is a risk of oxygen deprivation.

Fuel cells consume oxygen when generating electricity. If the vehicle is left in standby state in an enclosed area, the air may become deprived of oxygen, resulting in asphyxiation of any person(s) in the area. Make sure the area is well ventilated before turning the power system on. If the vehicle is in a garage, keep the door open.

WARNING

Do not attempt to modify, install, or disassemble the hydrogen-related components.

The hydrogen-related components are filled with hydrogen gas. Removing or disassembling these components may cause a hydrogen gas leak which can lead to a fire or explosion.

If you notice anything unusual about your vehicle, consult an authorized Honda Clarity Fuel Cell dealer.

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.

13

Guide Reference Quick

High Voltage Battery

Because electricity generated by the fuel cells and through regenerative braking recharges the High Voltage battery, the battery does not need to be recharged from an outside source; however, the High Voltage battery gradually discharges when the vehicle is not in use. If allowed to discharge too much, the battery may become damaged.

If your vehicle is parked for an extended period of time, during storage for example, periodically recharge the battery to maintain sufficient charge levels. At least once every three months, turn on the power system, and keep it on for more than 30 minutes to allow the battery to recharge.

Excessive heat can also damage the battery. On hot, sunny days, try to avoid parking your vehicle under direct sunlight.

If the High Voltage battery becomes fully discharged or damaged and you are unable to start the FC system as a result, consult an authorized Honda Clarity Fuel Cell dealer.

Temperature

When storing the vehicle, make sure not to expose it to extremely low temperatures: If the temperature of the fuel cell drops below –4°F (–20°C), the power system may not start. If the temperature drops to below –22°F (–30°C), the fuel cells or the High Voltage battery will not operate and, as a result, the vehicle will not start.

14

Hydrogen Leak Detection System

When the power mode is turned to ON, the hydrogen leak detection system is activated. If a hydrogen gas leak is detected by the hydrogen detector, the hydrogen leak indicator will

come on.

2 Hydrogen Leak Indicator (P88)

Hydrogen Supply/High Voltage Shut-off System

If the FC system is on and the vehicle is involved in a crash, depending on the severity of the impact, the shut-off system will cut off the supply of hydrogen and electricity. In this case, it is not possible to restart the vehicle.

To restart the FC system, consult an authorized Honda Clarity Fuel Cell dealer.

WARNING

Do not block the hydrogen ventilation ducts.

The hydrogen tanks, FC stack, and hydrogen supply components have ventilation ducts to allow any leaked hydrogen to escape into the atmosphere. If the opening of a duct is blocked with snow, leaves, etc., and a hydrogen leak occurs, the leaked gas can make its way into the motor room, where it can ignite, resulting in a fire or explosion.

Make sure the ducts are free of any obstructions before activating the power system.

Do not remove or disassemble a hydrogen duct: Doing so can lead to a fire or explosion if a hydrogen gas leak occurs.

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.

Honda Clarity Fuel Cell 2017 Owner’s Manual

Fuel Cell Insulating Fluid

Fuel cell insulating fluid (FC insulating fluid) uses a specifically designed fluid with high electrical insulation properties in order to safely cool the fuel cell.

Never add water, other commercial coolants, or genuine Honda inverter coolant to the cooling system. Doing so will cause damage to the fuel cell.

Consult an authorized Honda Clarity Fuel Cell dealer to replenish or change the fuel cell insulating fluid.

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 after 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 exhaust 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 pipe 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.

18

In Case of a Crash

If a vehicle fire occurs, leaked hydrogen gas may ignite. Stay far away from the vehicle and call the local fire department.

To extinguish a vehicle fire, use a large amount of water, dry chemical fire extinguisher (Class A, B, or C), or carbon dioxide fire extinguisher. With an inadequate amount of water, a fire cannot be put out completely. Never attempt to extinguish a vehicle fire with a small amount of water.

If your vehicle needs to be towed, make sure it is done with all the wheels lifted using the flat bed equipment. If the front wheels are touching the ground, the rotating tires will force the electric motor to spin, which in turn, may damage the power system, transmission, etc.

WARNING

If the body of the vehicle is seriously damaged or deformed in a crash, hydrogen gas may leak out from the vehicle. Keep flammable sources, such as a lit cigarette or

warning flares, away from the vehicle.

2 If Hydrogen Gas is Leaking (P487)

Also, high voltage parts and/or the cables (orange) connecting them may be exposed as a result of a crash. Stay clear of these parts as you may be electrocuted.

If the vehicle catches fire, leaked hydrogen gas may ignite. Stay far away from the vehicle and report to the fire department that a vehicle containing hydrogen tanks is on fire.

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 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.

WARNING

If a High Voltage battery fluid leaks, be careful not to touch the fluid. It can harm your eyes and skin. If it comes in contact with your eyes and skin; flush the affected area with clean water immediately for a few minutes, and seek immediate medical attention.

Do not use a warning flare near a fuel cell vehicle. If hydrogen gas is leaking, it may ignite the gas, and result in a vehicle fire.

Regenerative Energy and Regenerative Braking

When decelerating or while driving downhill, the electric motor acts as a generator that recover a portion of the electrical energy that was used to accelerate the vehicle.

In the following situations, the vehicle generates electricity while decelerating.

The accelerator pedal is released with the gear position in D.

The brake pedal is depressed with the gear position in D.

uWhen the High Voltage battery is fully charged or its temperature is too cold/hot, or another factor or factors are effecting the condition of the battery, the regenerative braking system may not be activated.
