Driving
LaneWatchTM
LaneWatch is an assistance system that al lows you to check the passenger side rear
areas displayed on the audio/information screen when the turn signal is activated to
the passenger’s side. A camera in the pa ssenger side door mirror monitors these
areas and allows you to check for vehicles, in addition to your visual check and use
of the passenger door mirror. You can also keep the system on for your convenience
while driving.1 LaneWatchTM
Important Safety Reminder
Like all assistance systems, LaneWatch has
limitations. Over reliance on LaneWatch may result in
a collision.
The LaneWatch func tion can be affected by weather,
lighting (including headli ghts and low sun angle),
ambient darkness, camera condition, and loading.
The LaneWatch may not prov ide the intended display
of traffic to the side and rear under the following
conditions:
•Your vehicle’s suspension has been altered,
changing the height of the vehicle.
•Your tires are over or under inflated.•Your tires or wheels are of varied size or
construction.
3WARNING
Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on LaneWatch while
driving.
Always look in your mi rrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.

you operate the turn signal lever.
• Display Time after Turn Signal Off: Changes the length of time the LaneWatch
display stays on after you pull the turn signal lever back.
• Reference Line : Selects whether the reference lines appear on the LaneWatch
monitor.
• Display : Allows for display adjustments of item s, such as brightness, contrast and
black level. This se tting is part of the System setup group.
2Customized Features P. 302
■Reference Lines
Three lines that appear on the screen can give
an idea of how far the vehicles or objects on
the screen are from your vehicle, respectively.
If an object is near line 1 (in red), it indicates
that it is close to your vehicle whereas an
object near line 3 is farther away.
1 LaneWatchTM
The LaneWatch camera view is restricted. Its unique
lens makes objects on the screen slightly look
different from what they are.
LaneWatch display does not come on when the gear
position is in
( R.
For proper LaneWatch operation:
•The camera is located in the passenger side door
mirror. Always keep this area clean. If the camera
lens is covered with dirt or moisture, use a soft,
moist cloth to keep the lens clean and free of debris.
•Do not cover the camera lens with labels or stickers
of any kind.
•Do not touch the camera lens.

1Reference Lines
The area around the reference line 1 (red) is very close to
your vehicle. As always, m ake sure to visually confirm
the safety of a lane chan ge before changing lanes.
The distance betwee n your vehicle and lines 1, 2 and
3 on the screen vary depending on road conditions
and vehicle loading. For ex ample, the reference lines
on the screen may seem to appear closer than the
actual distances when the rear of your vehicle is more
heavily loaded.
Consult an authorized Honda Clarity Fuel Cell dealer
if:
•The passenger side door mirr or, or area around it is
severely impacted, resulting in changing the
camera angle.
•The LaneWatch display doe s not come on at all.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)
Continued
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 does not prevent collisions
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. 439
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 385
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
behind the emblem.
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.

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)
Continued
Driving
• When there is a group of people in front of your vehicle walking together side by
side.
• Surrounding conditions or belongings of the pedestrian alter the pedestrian’s
shape, preventing the system from recogn izing that the person is a pedestrian.
• When the pedestrian is shorte r than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.
• When a pedestrian blends in with the background.
• When a pedestrian is bent over or squatting, or when their hands are raised or
they are running.
• When several pedestrians are walking ahead in a group.
• When the camera cannot correctly identify that a pedestrian is present due to an
unusual shape (holding luggage, body position, size).
■Automatic shutoff
The CMBSTM may automatically shut itself off and the CMBSTM indicator comes and
stays on when:
• The temperature inside the system is high.
• You drive off-road or on a mountain road, or curved and winding road for an
extended period.
• An abnormal tire condition is detected (wrong tire size, flat tire, etc.).
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
Once the conditions th at caused the CMBS
TM to shut off improve or are addressed
(e.g., cleaning), the system comes back on.
Limitations applicable to pedestrian detection only
