■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.
1LaneWatchTM*
The LaneWatch camera view is restricted. Its unique
lens makes objects on the screen slightly look
different from what they are.
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.

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 a 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.

Honda Sensing®
Honda Sensing® is a driver support system which employs the use of two distinctly
different kinds of sensors: a radar sensor located in the front lower grille and a front
sensor camera mounted to the interior side of the windshield, behind the rearview
mirror.
Honda Sensing® has following functions.

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 th e 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. 517
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 572
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 574
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 at the
lower part of the front
bumper.
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 the system determines
there is a chance of a collision with:
- Vehicles detected in front of you that ar e stationary, oncoming, or traveling in your
same direction.
- A pedestrian who is detected in front of you.
●Your vehicle speed is above 62 mph (100 km/h), and the system determines there
is a chance of a collision with a vehicle detected in front of you traveling in your
same direction.

■When the system activates
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.

1Collision Mitigation Braking SystemTM (CMBSTM)
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. 517
The head-up warning uses a lens located at the front
end of the dashboard.
Do not cover the lens or spill any liquid on it.

the stages before initiating the last stage.
