Hydrogen Gas Leak
If a hydrogen gas leak is suspected, follow the recommended actions listed in the
instructions of this manual. 2 If Hydrogen Gas is Leaking (P513)
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.

What to Do If
Why do I hear an operating
noise when applying the
brakes?This can occur when the ABS activates and does not indicate a
problem. Apply firm, steady pressure on the brake pedal. Never
pump the brake pedal.
2Anti-lock Brake System (ABS) (P433)
The rear door cannot be
opened from inside the
vehicle. Why?Check if the childproof lock is in
the lock position. If so, open the
rear door with the outside door
handle.
To cancel this function, slide the
lever up to the unlock position.
Why do the doors lock
after I unlocked the doors?If you do not open the doors within 30 seconds, the doors are
relocked automatically for security.

uuSeat Belts uAbout Your Seat Belts

Safe DrivingThe seat belt system in cludes an indicator on
the instrument panel to remind the driver or a
front passenger or both to fasten their seat
belts.
If you set the power mode to ON and a seat
belt is not fastened, a beeper will sound and
the indicator will blink. After a few seconds,
the beeper will stop and the indicator will
come on and remain illuminated until the seat
belt is fastened.
The beeper will periodically sound and the
indicator will blink while the vehicle is moving
until the seat belt is fastened.
The front seats are equipped with automatic
seat belt tensioners to enhance safety.
The tensioners automatically tighten the front
seat belts during a moderate-to-severe frontal
collision, sometimes even if the collision is not
severe enough to inflate the front airbags or
the driver’s knee airbag.
■Seat Belt Reminder1 Seat Belt Reminder
The indicator will also co me on if a front passenger
does not fasten their seat be lt within six seconds after
the power mode is set to ON.
When no one is sitting in th e front passenger’s seat,
the indicator will not come on and the beeper will not
sound.
The indicator also may no t come on and the beeper
may not sound when the occupant is not heavy
enough to trigger the weight sensor. Such occupants
(e.g., infants and smaller children) should be moved
to the rear seat as a deploying front airbag likely will
injure or kill them.

■Automatic Seat Belt Tensioners1Automatic Seat Belt Tensioners
The seat belt tensioners can only operate once.
If a tensioner is activated, the SRS indicator will come
on. Have an authorized Honda Clarity Fuel Cell dealer
replace the tensioner and thoroughly inspect the seat
belt system as it may not offer protection in a
subsequent crash.
During a moderate-to-severe side impact, the
tensioner on that side of the vehicle also activates.

Safe Driving
The front, driver’s knee, front side, and side
curtain airbags are deployed according to
the direction and severity of impact. Both
side curtain airbags are deployed in a
rollover. The airbag system includes:
aTwo SRS (Supplemental Restraint System)
front airbags. The driver’s airbag is stored
in the center of the steering wheel; the
front passenger’s airbag is stored in the
dashboard. Both are marked SRS
AIRBAG.
bDriver’s knee airbag. The knee airbag is
stored under the steering column. It is
marked SRS AIRBAG.
cTwo side airbags, one for the driver and
one for a front passenger. The airbags are
stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG .
dTwo side curtain airbags, one for each
side of the vehicle. The airbags are stored
in the ceiling, above the side windows.
The front and rear pillars are marked
SIDE CURTAIN AIRBAG.
eAn electronic control unit that, when the
power mode is in ON, continually
monitors information about the various
impact sensors, seat and buckle sensors,
rollover sensor, airbag activators, seat
belt tensioners and other vehicle
information. During a crash event the
unit can record such information.
fAutomatic front seat belt tensioners. In
addition, the driver’s and front
passenger’s seat belt buckles incorporate
sensors that detect whether or not the
belts are fastened.
gDriver’s seat position sensor. This sensor
detects the driver’s seat slide position to
help determine the optimal deployment
of the driver’s airbag.
hWeight sensors in the front passenger’s
seat. The sensors are used for occupant
classification to activate or deactivate the
front passenger’s airbag.
iImpact sensors that can detect a
moderate-to-severe front or side impact.
jAn indicator on the dashboard that alerts
you that the front passenger’s front
airbag has been turned off.
kAn indicator on the instrument panel that
alerts you to a possib le problem with your
airbag system or seat belt tensioners.
lA rollover sensor that can detect if your
vehicle is about to roll over and signal the
control unit to deploy both side curtain
airbags.

uuAirbags uFront Airbags (SRS)
Safe DrivingFront airbags are designed to inflate duri ng moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won’t interfere with the driver’s visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until th ey see them lying in front of them.
■Operation
■How the Front Airbags Work1How the Front Airbags Work
Although the driver’s and fr ont passenger’s airbags
normally inflate within a spli t second of each other, it
is possible for only one airbag to deploy. This can
happen if the severity of a collision is at the margin,
or threshold that determines whether or not the
airbags will deploy. In such cases, the seat belt will
provide sufficient protec tion, and the supplemental
protection offered by the airbag would be minimal.

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 deal er, or call American Honda Automobile
Customer Service at 1-800-999-1009.
