422 uu When Driving u Vehicle Stability Assist (VSA ® ), aka Electronic Stability Control (ESC), System
Driving Vehicle Stability Assist (VSA ® ), aka Electronic
Stability Control (ESC), System VSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine and motor output and selectively applying the
brakes.
When VSA ® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic system . You will also see
the indicator blink.
■ VSA ® Operation 1 Vehicle Stability Assist (VSA ® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by an authorized
Honda Clarity Plug-In Hybr id dealer immediately.
The indicators for the Vehicle Stability Assist (VSA ® )
System, Vehicle Stability Assist (VSA ® ) OFF, low tire
Pressure/TPMS and Collision Mitigation Braking
System TM
(CMBS TM
) may come on along with a
message in the driver information interface after
reconnecting the 12-volt battery. Drive a short
distance at more than 12 mph (20 km/h). The
indicator should go off. If it does not, have your
vehicle checked by an aut horized Honda Clarity Plug-
In Hybrid dealer.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stab ility Control (ESC). The
system also includes a traction control function.VSA ® System

424 uu When Driving u Agile Handling Assist
Driving Agile Handling Assist Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehi cle’s stability and performance during
cornering. 1 Agile Handling Assist
The agile handling assist ca nnot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not
activate.
You may hear a sound coming from the engine
compartment while the agile handling assist is
activated. This is normal.18 CLARITY PHEV CSS-31TRW6000.book 424 ページ ２０１７年８月３１日　木曜日　午後２時４９分

Driving
Braking Brake System Use the parking brake to keep the vehicl e stationary when parked. When the
parking brake is applied, you can manu ally or automatically release it.
■ To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the power mode is in.
Pull the electric parking brake switch up gently
and securely.
u The parking brake and brake system
indicator (red) comes on.
■ To release
The power mode must be in ON in order to
release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The parking brake and brake system
indicator (red) goes off.
Manually releasing the parking brake using
the switch helps your vehicle start slowly and
smoothly when facing down hill on steep hills.■ Parking Brake 1 Brake System
When you depress the brak e pedal, you may hear a
whirling sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parki ng brake, or set the power
mode to OFF. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead.
2 Jump Starting P. 539
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the electric servo brake
system until the vehicle comes to a stop. The
electric parking brake then applies, and the
switch should be released.Electric Parking

433 uu Braking u 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 an ti-lock brake system (ABS) helps you retain steering
control when brak ing very hard.2 Brake Assist System P. 438
2 Anti-lock Brake System (ABS) P. 437
■ Foot Brake 1 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 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 aut horized Honda Clarity Plug-
In Hybrid dealer. If you hear only an occasional
squeak or squeal when y ou initially apply the brake
pedal, this may be nor mal and caused by high
frequency vibration of th e brake pads against the
rotating brake disc.18 CLARITY PHEV CSS-31TRW6000.book 433 ページ ２０１７年８月３１日　木曜日　午後２時４９分

Driving 1 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 regenerati ve 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 conf use drivers behind you.18 CLARITY PHEV CSS-31TRW6000.book 434 ページ ２０１７年８月３１日　木曜日　午後２時４９分

437uu Braking u 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 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 pu mp 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 unde r 6 mph (10 km/h), the ABS stops.■ ABS 1 Anti-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 lockup 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 sou nds are normal to ABS
systems and are no cause for concern.18 CLARITY PHEV CSS-31TRW6000.book 437 ページ ２０１７年８月３１日　木曜日　午後２時４９分
