1Blind spot information System*
Blind spot information sy stem may be adversely
affected when:
•Objects (guard rails, poles, trees, etc,.) are
detected.
•An object that does not re flect radio waves well,
such as a motorcycle, is in the alert zone.
•Driving on a curved road.•A vehicle is moving from a far lane to the adjacent
lane.
•The system picks up external electrical interference.•The rear bumper or the sensors have been
improperly repaired or the rear bumper has been
deformed.
•The orientation of the sensors has been changed.
•In bad weather (Heavy rain, snow, and fog).
•Making a turn at an intersection.•Driving on a bumpy road.
•Making a short turn that slightly tilts the vehicle.
For proper blind spot information system operation:
•Always keep the rear bumper corner area clean.
•Do not cover the rear bumper corner area with
labels or sticke rs of any kind.
•Take your vehicle to a dealer if you need the rear
bumper corner area or the radar sensors to be
repaired, or the re ar bumper corner area is strongly
impacted.

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

Driving
Collision Mitigati on 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 the
potential for a collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
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 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:

Driving
■How the system works
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. The radar sensor is
in the front grille.
The CMBS
TM 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 are 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. The camera is
located behind the
rearview mirror.
When to use
1
How the system works
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 system has three alert stages for a possible collis ion. However, depending on circumstances, the CMBSTM may not go through all of
the stages before initiating the last stage.

The system may automatically shut off and the CMBSTM indicator will come on under
certain conditions. Some examples of these conditions are listed below. Other
conditions may reduce some of the CMBS
TM functions.

■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 objects and the background.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Roadway objects or structures are misinterpreted as vehicles and pedestrians.
• Reflections on the interior of the front windshield.
• Driving at night or in a dark place such as a tunnel (due to low-light conditions,
pedestrians or other vehicles may not be detected).
■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on curvy, winding, or undulating roads.
• The road is hilly or the vehicle is approaching the crest of a hill.

• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter or other small
vehicle.
• When there are animals in front of your vehicle.

Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow
Helps maintain a constant vehicle speed and a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follo w slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow
Important Reminder
As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 548
3WARNING
Improper use of ACC with Low Speed
Follow can lead to a crash.
Use ACC with Low Speed Follow only
when driving on expressways or
freeways and in good weather
conditions.
3WARNING
ACC with Low Speed Follow has limited
braking capability and may not stop
your vehicle in time to avoid a collision
with a vehicle that qu ickly stops in front
of you.
Always be prepared to apply the brake
pedal if the cond itions require.
When to use
■Vehicle speed for ACC wi th Low Speed Follow: A vehicle is detected ahead
within ACC with Low Speed Follow range – ACC with Low Speed Follow
operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with Low Speed Follow range – ACC with
Low Speed Follow operates at the speed of 25 mph (40 km/h) or above.
■Shift position for ACC with Low Speed Follow: In ( D.
The radar sensor is
inside the front grille.
The camera is
located behind
the rearview
mirror.

■How to activate the system1Adaptive Cruise Control (ACC) with Low Speed Follow
You can read about handling information for the
camera equipped with this system.
2 Front Sensor Camera P. 546
When the MAIN button is pressed, both ACC with
Low Speed Follow and the Lane Keeping Assist
System (LKAS) are either turned on or off.
ACC with Low Speed Follow may not work properly
under certain conditions.
2 ACC with Low Speed Follow Conditions
and Limitations P. 522
When not using ACC with Low Speed Follow: Turn
off adaptive cruise by pressing the MAIN button. This
also will turn off the Lane Keeping Assist System
(LKAS).
Do not use ACC with Low Speed Follow under the
following conditions:
•On roads with heavy traf fic or while driving in
continuous stop and go traffic.
•On roads with sharp turns.•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC with Low Speed Follow will not apply
the brakes to maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
How to use
■Press the MAIN button on
the steering wheel. ACC (green) is on in the
driver information
interface.
ACC with Low Speed
Follow is ready to use.
