Honda Sensing®
Honda Sensing® is a driver support system which employs the use of two distinctly
different kinds of sensors: the sonar sens ors located in the front and rear bumpers,
and the front grille, and a front wide view camera mounted to the interior side of
the windshield, behind the rearview mirror.
Honda Sensing ® is a driver support system which employs the use of a front wide
view camera mounted to the interior side of the windshield, behind the rearview
mirror.
Honda Sensing ® has the following functions.

Driving
The system has three alert stages for a possible collision. However, depending on circumstances, the CMBSTM may not go through all of
the stages before initiating the last stage.

Continued
Driving
Low Speed Braking Control*
Using sonar sensors located on the front an d rear bumpers, and the front grille, this
system detects if there is danger of a poten tial collision with a wall or other obstacle
during normal driving or when the accelerator pedal is depres sed with too much
force. The system then assists in avoiding collisions and reducing damage from
impact through assistive braking and/or assistive driving power suppression.
1Low Speed Braking Control*
If the Low Speed Braking Control activates in a
situation where you do not want automatic brake
application (such as when the vehicle is between two
railroad crossing gates), si mply press the brake pedal
to deactivate the system and then continue to drive
as intended.
3WARNING
The Low Speed Braking Control System
cannot avoid all collisions and may not
reduce damage in each situation where the
accelerator is mistaken ly or aggressively
pressed. Overreliance on the system may
result in a collision with serious injury or
death. Always check your surroundings,
your shift position, and your pedal use.
Driver remains responsible for safely
operating the vehicle.

■Assistive braking
Assistive braking provides a visual and audible alert when the vehicle is moving
between approximately 1 and 6 mph (2 and 10 km/h) and there is the possibility of
a collision with a detected wall or other ob stacles, as well as providing assistance
with braking.
If the only rear sensors are turned off usin g the parking sensor system, the assistive
braking will not work when reversing.

sensors, please refer to the following page.

In order to prevent the sy stem from activating when
not needed, always turn it off during vehicle
maintenance, when loading on ships, trucks, and so
on, or when using a chassis dynamometer, free
rollers for inspection or when washing the car in
conveyor type car wash machine.
If you put any accessories (such as a bicycle rack) on
or around the rear sensors, the Low Speed Braking
Control System may activate if it detects these
accessories as an obstacle. In this case, turn off the
rear sensor.

■Assistive driving power suppression
When the vehicle is stopped or moving at less than 6 mph (10 km/h) and there is an
obstacle such as a wall detected near the front of or back of the vehicle, if the
accelerator pedal is depressed more than necessary, the system wi ll inform you with
a visual and audible alert. At the same ti me, the system will prevent sudden forward
or backwards movement by limiting the output of the engine, then assistive braking
will activate when you ge t closer to the obstacle.
Assistive driving power suppression will not activate in the fo llowing situations.
When moving forward:
When on a steep slope or the shift position is in
(P, (R, or (N.
When reversing:
When on a steep slope or the shift po sition is in a position other than
(R.
If the only rear sensors are turned off usi ng the parking sensor system, the assistive
driving power suppression will not work when reversing.

Conditions for assistive driving power suppression.
• When the accelerator is no longer depressed.
• When the accelerator is depresse d for approximately four seconds.
• When the brake pedal is depressed.
Conditions for assistive braking cancellation.
• A certain amount of time has passed since activation.
The system may not operate correct ly in the following conditions:
■Examples of obstacles the sonar sensor cannot detect
• Obstacles that do not reflect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fences , bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Moving objects or obstacles that suddenly enter the road.
• Obstacles that are not perp endicular to the ground.
■Conditions for Cancellation
■Low Speed Braking Control System Conditions and Limitations
1Conditions for Cancellation
After Low Speed Braking Control has activated once,
it will not activate again for the same obstacle.
They can be activated again after driving for a certain
distance after last activation.
Low Speed Braking Control ac tivates separately when
moving forward and reversing. (For example, if it
activates when moving forwar d, it can be activated
again immediately if reversing.)
However, if assistive braking has been activated, in
order to activate assistiv e driving power suppression
again, it is necessary to drive for a certain distance to
reset the system.

Driving
■Examples of situations where the so nar sensor cannot detect obstacles
• The sonar sensor is dirty (covered by snow, water, mud, etc.).
• The vehicle is too hot or cold.
• The steering wheel is turned sharply when approaching the obstacle at an angle.
■Examples of other cases where the system may not work correctly
• The vehicle is tilted due to heavy load or suspension modifications.
• An abnormal tire or wheel condition (incor rect sizes, varied sizes or construction,
improperly inflated, comp act spare tire, etc.).
• Bad weather conditions such as heavy rain, fog, snow, sandstorms, etc.
• The ambient temperature/humidity is too high or low.
• When going down a very steep slope.
• When close to other vehicles with sonar sensors or other objects that emit
ultrasonic waves.
■Situations where the system may activa te even without risk of a collision
• When passing through short or narrow gates.
• When driving on uneven surfaces, gr assy areas, or places with steps.
• When a sloped pillar or wall is protruding from a high position.
• When there are obstacles next to the road.
• When driving toward flags, curtains, tree branches, railroad crossing bars, etc.
• When driving on flooded roads.
