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  (P511)
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.

Safe Driving
For Safe Driving
The following pages explain your vehicle’s safety features and how to use them 
properly. The safety precauti ons below are ones that we consider to be among the 
most important.
Important Safety Precautions
■Always wear your seat belt
A seat belt is your best protection in all types of collisions. Airbags are designed to 
supplement seat belts, not replace them. So  even though your vehicle is equipped 
with airbags, make sure you and your passe ngers always wear your seat belts, and 
wear them properly.
■Restrain all children
Children ages 12 and under should ride properly restrained in a back seat, not the 
front seat. Infants and small children shoul d be restrained in a child seat. Larger 
children should use a booster seat and a lap/shoulder seat belt until they can use the 
belt properly without a booster seat.
■Be aware of airbag hazards
While airbags can save lives, they can cause serious or fatal injuries to occupants 
who sit too close to them, or are not prop erly restrained. Infants, young children, 
and short adults are at the greatest risk.  Be sure to follow all instructions and 
warnings in this manual.
■Don’t drink and drive
Alcohol and driving don’t mix. Even one dr ink can reduce your ability to respond to 
changing conditions, and your reaction time gets worse with every additional drink. 
So don’t drink and drive, and don’t let  your friends drink and drive, either.
1Important Safety Precautions
Some states and territorie s prohibit the use of cell 
phones other than hands-free devices by the driver 
while driving.

Safe Driving
Types of Airbags
Your vehicle is equipped with four types of airbags:
• Front airbags:  Airbags in front of the driver ’s and front passenger’s seats.
• Driver’s knee airbag:  Airbag under the steering column.
• Side airbags:  Airbags in the driver’s and  front passenger’s seat-backs.
• Side curtain airbags:  Airbags above the side windows.
Each is discussed in the following pages.
Front Airbags (SRS)
The front SRS airbags inflate in a moderate-to -severe frontal collision to help protect 
the head and chest of the driver and/or front passenger.
SRS  (Supplemental Restraint System) indica tes that the airbags are designed to 
supplement seat belts, not replace them.  Seat belts are the occupant’s primary 
restraint system.
The front airbags are housed  in the center of the steering wheel for the driver, and 
in the dashboard for the front pass enger. Both airbags are marked SRS AIRBAG.
■Housing Locations
1Types of Airbags
The airbags can inflate whenever the power mode is 
in ON.
After an airbag inflates in a crash, you may see a 
small amount of smoke. This is from the combustion 
process of the infl ator material and  is not harmful. 
People with respiratory pr oblems may experience 
some temporary discomfort. If  this occurs, get out of 
the vehicle as soon as it is safe to do so.
1 Front Airbags (SRS)
During a frontal crash severe  enough to cause one or 
both front airbags to deploy, the airbags can inflate 
at different rates, dependi ng on the severity of the 
crash, whether or not the se at belts are latched, and/
or other factors. Frontal airbags are designed to 
supplement the seat belts to help reduce the 
likelihood of head and chest injuries in frontal 
crashes.

uuAirbags uFront Airbags (SRS)
Safe DrivingThe airbags have advanced features to he lp reduce the likelihood of airbag related 
injuries to smaller occupants. The driver’s advanced airbag system includes a 
seat position sensor.
Based on information from this sensor and the 
severity of the impact, the advanced airbag 
system determines the optimal deployment of 
the driver’s airbag.
The front passenger’s ad vanced airbag system 
has weight sensors.
We advise against allowi ng a child age 12 or 
under to ride in the front passenger’s seat. 
However,  if you do allow a child age 12 or 
under to ride in the front passenger’s 
seat , note that the system will automatically 
turn off the front passenger’s airbag if the 
sensors detect that the child is approximately 
65 lbs (29 kg) or less.
■Advanced Airbags1 Advanced Airbags
If there is a problem with the driver’s seat position 
sensor, the SRS indicator wi ll come on, and in the 
event of a crash, the airbag  will deploy (regardless of 
the driver’s seating position) with a force 
corresponding to the se verity of the impact.
For the advanced airbags to work properly:
•Do not spill any liquid on or under the seats.
•Do not put any object under the passenger’s seat.
•Make sure any objects are positioned properly on 
the floor. Improperly pos itioned objects can 
interfere with the advanced airbag sensors.
•All occupants should sit upri ght and wear their seat 
belts properly.
•Do not cover the passenger ’s side dashboard with 
a cloth, towel, cover, etc. 2 Passenger Front Airbag Off Indicator P. 68
Make sure the floor mat  behind the front passenger's 
seat is hooked to the floor  mat anchor. An improperly 
placed mat can interfere with the advanced airbag 
sensors.
