uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The an ti-lock brake system (ABS) helps you retain steering
control when brak ing very hard.

■Foot Brake1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by an authorized Honda Clarity Fuel
Cell dealer. If you hear onl y an occasional squeak or
squeal when you initially a pply the brake pedal, this
may be normal and caus ed by high frequency
vibration of the brake pads against the rotating brake
disc.
Constantly using the brak e pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness.
To help reduce heat build -up in the brakes when
descending a long slope, use regenerative braking to
slow the vehicle down.
When the high voltage battery is recharging,
regenerative braking may not be possible.

Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, a nd helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
You may hear an operating noise when the ABS is working. Keep holding the pedal
firmly down. On dry pavement, you will need to press on the brake pedal very hard
before the ABS activates. However, you may feel the ABS activate immediately if you
are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correc tly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking will not be affected, there is a
possibility that the ABS wi ll not be operating. Have
your vehicle checked by an authorized Honda Clarity
Fuel Cell dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with tire chains.
The following may be observed with the ABS system:
•Motor sounds coming from the motor
compartment when the brakes are applied, or
when system checks are being performed after the
power system has been turned on and while
vehicle accelerates.
•Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sounds are normal to ABS
systems and are no cause for concern.

■Vibration alert on the steering wheel
When a potential collision to an oncoming detected vehicle is determined, the
system alerts you with rapid vibration on the steering wheel, in addition to visual and
audible alerts. u Take appropriate action to prevent a col lision (apply the brakes, operate the
steering wheel, etc.).

pedestrians.
However, this pedestrian detection feature may not
activate or may not detect a pedestrian in front of
your vehicle under certain conditions.

Handling the Unexpected
If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a smal l puncture, from a nail for instance, you can
use the temporary tire repair kit so that you can drive to the nearest service station
for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and non-slippery surface and apply the parking
brake.
2. Change the gear position to
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF
(LOCK).
1 Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact an authorized Honda Clarity Fuel
Cell dealer or a roadside assistance to have the
vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.
•The puncture or cut is larger than 3/16 inch (4 mm).
•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tires
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
When the puncture is:Kit Use

Handling the Unexpected
Emergency Power System Off
The POWER button may be used to turn the power system off due to an emergency
situation even while driving. If you must tu rn the power system off, do either of the
following operations:
• Press and hold the POWER button for about two seconds.
• Firmly press the POWER button three times.
The steering wheel will not lock. However, because turning off the power system
disables the power assist the power syst em provides to the steering and braking
systems, it will require significantly more physical effort and time to steer and slow
the vehicle. Use both feet on the brake pe dal to slow down the vehicle and stop
immediately in a safe place.
The gear position auto matically changes to
(P after the vehicle comes to a complete
stop. Then, the power mode changes to VEHICLE OFF.
1 Emergency Power System Off
Do not press the button while driving unless it is
absolutely necessary for the power system to be
turned off.
