uuWhen Driving uAdaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Driving
■Automatic ca ncellation
The beeper sounds and a message appears on the driver information interface and
the head-up display when ACC with LSF is automatically canceled. Any of these
conditions may cause the ACC with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the AC C with LSF range is too close to your
vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation ca n be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastene d when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The power system is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically
canceled, you can still resu me the prior set speed.
Wait until the condition that caused ACC with LSF to
cancel improves, then press the RES/+ button.

uuWhen Driving uLane Keeping Assist System (LKAS)
Driving
■The LKAS may automatically be canceled when:
• The camera temperature gets extremely high or low.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• The ABS or VSA ® system engages.
The beeper sounds if the LKAS is automatically canceled.
The system may not detect lane markings and therefore may not keep the vehicle in
the middle of a lane under certain conditions, including the following:
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between la ne lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interi or of the windshield.

■To release automatically
Depressing the accelerator pedal releases the parking brake.
Use the accelerator pedal to release th e brake when you are starting the vehicle
facing uphill, or in a traffic jam.
Gently depress the accelerator pedal.
When on a hill, it may require more
accelerator input to release.u The parking brake and brake system
indicator (red) goes off.
You can release the parki ng brake automatically when:
• You are wearing the driver’s seat belt.
• The power system is on.
• The transmission is not in
(P or (N.
1Parking Brake
If the parking brake cannot be released
automatically, release it manually.
When the vehicle is travel ing uphill, the accelerator
pedal may need to be pressed farther to
automatically release the electric parking brake.
The parking brake may not be released automatically
while the following indicators are on:
•POWER SYSTEM indicator•Transmission system indicator
•Parking brake and brake sy stem indicator (amber)
•VSA® system indicator•ABS indicator
•Supplemental restraint system indicator

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.
