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 distribu tion (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 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 ne ed to press on the brake pedal very hard
before the ABS activates. Ho wever, you may feel the ABS activate immediately if you
are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes under 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 will not operating. Have your
vehicle checked by an aut horized 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 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 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 ve hicle body vibration when
ABS activates.
These vibrations and sounds are normal to ABS
systems and are no cause for concern.

Driving
Collision Mitigation Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM 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 SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It do es not prevent a collision
nor stop the vehicle automati cally. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our 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 coll ision 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 ah ead when your vehicle speed is about 3
mph (5 km/h) and there is a vehicle in front of you.
When to use
The CMBSTM 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.

At system’s earliest collision alert stage, you can change the distance ( Long/
Normal /Short) between vehicles at which alerts will come on through audio/
information screen setting options.
2 Customized Features P. 306
■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 co llision (apply the brakes, operate the
steering wheel, etc.).
1 When the system activates
The camera in the CMBS
TM is also designed to detect
pedestrians.
However, this pedestrian detection feature may not
activate or may not detect a pedestrian in front of
your vehicle under certain conditions.
Refer to the ones indicating the pedestrian detection
limitations from the list. 2 CMBS
TM Conditions and Limitations P. 443
The system provides visual, audible and tactile alerts of a possible collision, and
stops if the collision is avoided.

When Stopped
1.Depress the brake pedal firmly.
2. With the brake pedal depressed, pull up th e electric parking brake switch slowly,
but fully.
3. Change the gear position to

4. Turn off the power system.
u The parking brake and brake system in dicator (red) goes off in about 15
seconds.
1 Parking Your Vehicle
Do not park your vehicle near flammable objects,
such as dry grass, oil, or timber.
Heat from the exhaust can cause a fire.
3WARNING
The vehicle can roll aw ay if left unattended
without confirming that Park is engaged.
A vehicle that rolls away could cause a crash
resulting in seriou s injury or death.
Always keep your foot on the brake pedal
until you have confirmed that
( P is shown
on the gear position indicator.
1 When Stopped
NOTICE
The following can damage the driveline:
•Depressing the accelera tor and brake pedals
simultaneously.
•Holding the vehicle in place when facing uphill by
depressing the accelerator pedal.
•Changing into ( P before the vehicle stops
completely.

Driving
Always confirm the electric parking brake is se t, in particular if you are parked on an
incline.1 When Stopped
When facing uphill, do not hold the vehicle by
depressing the accelerator pedal.
Doing so may cause the power system to overheat
and fail.
In extremely cold temperatures, the parking brake
may freeze up if applied. If such temperatures are
expected, do not apply the parking brake but, if
parking on a slope, either turn the front wheels so
they will contact the curb if the vehicle rolls down the
slope or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the
vehicle may roll unexpect edly, leading to a crash.
