uuWhen Driving uLane Keeping Assist System (LKAS)
Driving
■The system operation is suspended if
you:
• Set the wipers to continuous operation.
u Turning the wipers off resumes the
LKAS.
• Decrease the vehicle speed to about 40
mph (64 km/h) or less.
u Increasing the vehicle speed to about 45
mph (72 km/h) or more resumes the
LKAS.
• Depress the brake pedal.
u The LKAS resumes and starts detecting
the lane lines again once you release the
brake pedal.
■The LKAS may automatically be suspended when:
• The system fails to detect lane lines.
• The steering wheel is quickly turned.
• You fail to steer the vehicle.
• Driving through a sharp curve.
• Driving at a speed in excess of approximately 90 mph (145 km/h).
Once these conditions no longer exis t, the LKAS automatically resumes.
When the LKAS is suspended,
the lane lines on the driver
information interface change to
contour lines, and the beeper
sounds (if activated).

uuWhen Driving uVehicle Stability Assist ® (VSA ®), aka Electronic Stability Control (ESC), System
Continued
Driving
Vehicle Stability Assist ® (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering 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 motor out put and selectively applying the brakes.
When VSA ® activates, you may notice that the
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 Electric dealer immediately.

System
TM (CMBSTM) may come on along with a
message in the driver information interface after re-
connecting 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
authorized Honda Clarity Electric 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 Stability Control (ESC). The
system also includes a traction control function.VSA® System

Agile Handling Assist
Lightly brakes the front wheels, as needed , when you turn the steering wheel, and
helps support the vehicle’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 motor
compartment while the agile handling assist is
activated. This is normal.

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can ma nually 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 parkin g brake switch up gently
and securely.
u The parking brake and brake system
indicator (red) comes on.
■Parking Brake1Brake System
When you depress the brak e pedal, you may hear a
whirling sound from the moto r 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. 514
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the VSA ® system until the
vehicle comes to a stop. The electric parking
brake then applies, and the switch should be
released.

In the following situations, the parking brake
automatically operates.
•When the vehicle stops more than 10 minutes
while ACC with LSF is activated.
•When the driver’s seat belt is unfastened while your
vehicle is stopped automatically by ACC with LSF.
•When the power system is turned off while ACC
with LSF is activated.
•When the vehicle stops with the automatic brake
hold system activated for more than 10 minutes.
•When the driver’s seat belt is unfastened while
your vehicle is stopped and brake hold is applied.
•When the power system is turned off while brake

Gently depress the accelerator pedal.
When on a hill, it may require more
accelerator input to release.u The parking brake and brake system

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 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 Electric
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.
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.
