Brake 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 anti-lock brake system (ABS) helps you retain steering
control when braking very hard.

Foot 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 metallic 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 Plug-
In Hybrid dealer. If you hear only an occasional
squeak or squeal when you initially apply the brake
pedal, this may be normal and caused by high
frequency vibration of the brake pads against the
rotating brake disc.

Foot Brake

Applying constant pressure to the brakes while going
down a long hill can cause the brakes to heat up,
resulting in a loss of stopping power. Therefore,
when descending a long hill, release the accelerator
pedal and allow regenerative braking to slow the
vehicle down. To adjust the rate of deceleration, use
the deceleration paddle selector.
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 confuse drivers behind you.

Anti-lock Brake System (ABS)

Driving

Anti-lock Brake System (ABS)

Helps prevent the wheels from locking up, and 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 distribution 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 pedal. 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 under 6 mph (10 km/h), the ABS stops.

ABS

1

Anti-lock Brake System (ABS)

NOTICE

The ABS may not function correctly 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 will not operating. Have your
vehicle checked by an authorized Honda Clarity Plug-
In Hybrid 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 lockup which can lead to
skidding and loss of steering control.

In the following cases, your 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 snow chains.

The following may be observed with the ABS system:

Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
power system has been turned on and while
vehicle is accelerates.

Brake pedal and/or the vehicle body vibration when
ABS activates.

These vibrations and sounds are normal to ABS
systems and are no cause for concern.

Continued

Driving

Collision Mitigation Braking System

TM

(CMBS

TM

)

Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBS

TM

is designed to alert you when a

potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.

How the system works

1

Collision Mitigation Braking System

TM

(CMBS

TM

)

Important Safety Reminder
The CMBS

TM

is designed to reduce the severity of an

unavoidable collision. It does not prevent a collision
nor stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately according to the driving
conditions.

The CMBS

TM

may not activate or may not detect a

vehicle in front of your vehicle under certain
conditions:

2 CMBS

TM

Conditions and Limitations P. 443

You can read about handling information for the
camera equipped with this system.

2 Front Sensor Camera P. 394

Be careful not to severely impact the radar sensor
cover.

1

How the system works

Rapid vibrations on the steering wheel alert you
when the your vehicle speed is between 19 and 62
mph (30 and 100 km/h) with an oncoming vehicle
detected in front of you.

When the CMBS

TM

activates, it may automatically

apply the brake. It will be canceled when your vehicle
stops or a potential collision is not determined.

The radar sensor is
in the front grille.

The camera is
located behind
the rearview
mirror.

The system starts monitoring the roadway ahead when your vehicle speed is about 3
mph (5 km/h) and there is a vehicle in front of you.

When to use

The CMBS

TM

activates when:

The speed difference between your vehicle and a vehicle or pedestrian detected
in front of you becomes about 3 mph (5 km/h) and over with a chance of a
collision.

Your vehicle speed is about 62 mph (100 km/h) or less and there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you.
