Driving
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 lo wer grille and a front
sensor camera mounted to the interior side of the windshield, behind the rearview
mirror.
Honda Sensing ® has following functions.

510 uu Honda Sensing ® u Collision Mitigation Braking System TM
(CMBS TM
)
Driving Collision Mitigati on Braking System TM
(CMBS TM
)Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBS TM
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 System TM
(CMBS TM
)
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 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:

camera equipped with this system.
2 Front Sensor Camera P. 568
For directions on the prop er handling of the radar
sensor, refer to the following page.
2 Radar Sensor P. 570
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 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 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.

may not go through all of
the stages before initiating the last stage.

Driving The system may automatically shut off and the safety support indicator (amber) will
come on under certain conditions. Some ex amples of these conditions are listed
below. Other conditions may reduce some of the CMBS TM
functions.2 Front Sensor Camera P. 568
■ Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, su ch 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 reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Roadway objects or structures are misint erpreted as vehicles and pedestrians.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■ Roadway conditions
• Driving on a snowy or wet roadway (obscured 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.■ CMBS TM

Driving
Adaptive Cruise Control (ACC) with Low Speed Follow (LSF) *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 LSF slows your vehicle by applying the brakes, your vehicle’s brake
lights will illuminate. 1 Adaptive Cruise Control (ACC) with Low Speed Follow (LSF) *
Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always
keep a safe interval betw een your vehicle and other
vehicles.3
WARNING Improper use of ACC with LSF can lead
to a crash.
Use ACC with LSF only when driving on
expressways or freeways and in good
weather conditions.
3
WARNING ACC with LSF has limited braking
capability and may not stop your vehicle
in time to avoid a co llision with a vehicle
that quickly 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 with LSF: A vehicle is detected ahead within ACC with
LSF range – ACC with LSF operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with LSF range – ACC with LSF operates at
the speed of 25 mph (40 km/h) or above.

cleaning the radar sensor cover. Clean it with water
or a mild detergent.
Do not put a sticker on the radar sensor cover or
replace the radar sensor cover.
If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by pressing the MAIN
button and take your vehicle to a dealer.
Have your vehicle checked by a dealer if you find any
unusual behavior of the sy stem (e.g., the warning
message appears too frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehi cle checked by a dealer:
• The vehicle mounted onto a bump, curb, chock,
embankment, etc.
• You drive the vehicle where the water is deep.
• Your vehicle has a frontal collision.
