uuHonda Sensing ®u Collision Mitigation Braking SystemTM (CMBSTM)
Driving
■How the system works
The CMBS
TM will be canceled when your vehicle stops or the system determines
there no longer is the potential for a collision.
The CMBS
TM may also be canceled when a dr iver operates the steering wheel and
the brake or accelerator pe dal to avoid a collision.
1How the system works
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. 577
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.
Models with head-up display
Lens
A front sensor
camera is located
behind the
rearview mirror.
The system starts monitoring the roadway ahead when your vehicle speed is about
3 mph (5 km/h) or above and will search for a vehicle, pedestrian, or moving bicycle
in front of you.
The CMBS
TM activates when:●The speed difference between your vehicl e and a vehicle, pedestrian, or moving
bicycle detected in front of you becomes about 3 mph (5 km/h) and over with a
chance of a collision.
●Your vehicle drives at about 18 mph (30 km/h) or less and there is a chance of a
frontal collision with a detected oncoming vehicle when you turn left at an
intersection.
●Your vehicle speed is about 62 mph (100 km /h) or less and the system determines
there is a chance of a collision with:
- An oncoming or stationary vehicle detected in front of you.
- A pedestrian or moving bicycle detected in front of you.
When to use
The radar sensor is
behind the Honda
emblem on the
front grille.

■Automatic shutoff
The CMBSTM may automatically shut itself off an d the safety support indicator (amber)
comes and stays on when:
• You drive off-road or on a mountain road, or curved and winding road for an
extended period.
• Driving in bad weather (rain, fog, snow, etc.).
• Driving with the parking brake applied.
• The camera temperature gets too high.
• The radar sensor temperature gets too high.
• The front of the camera or radar sensor behind the Honda emblem is covered by
dirt, fog, rain, mud, wet snow, seals, accessories, stickers, or film on the
windshield.
• An abnormal tire condition is detected (incorrect tire size, flat tire, etc.).
• You are driving near an object or plac e that generates strong radio waves or
noise, such as a TV tower, broadcast station, power pl ant, or a vehicle equipped
with radar.
Once the conditions that caused the CMBS
TM to shut off improve or are addressed
(e.g., cleaning), the system comes back on.

Driving
Low Speed Braking Control*
Using sonar sensors located on the front and rear bumpers, this system can detect if
there is danger of a potential collision with a wall or other obstacle during normal
driving or when the accelerator pedal is de pressed with too much force. The system
then assists in avoiding collisions an d reducing damage from impact through
assistive braking and/or assistive driving power suppression.1 Low 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), simply 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 mistakenly 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 usi ng the parking sensor system, the assistive
braking will not work when reversing.

■How the System Works1Low Speed Braking Control*
For directions on the prop er handling of the sonar
sensors, please refer to the following page.
2 Sonar Sensors
* P. 651
The vehicle will release the brake and start moving a
few seconds after the system is activated. To keep the
vehicle stopped, keep the brake pedal depressed or
put the transmission into
( P.
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 th e front or back of the vehicle, if the
accelerator pedal is depressed more than necessary, the system will 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 outpu t of the engine, then assistive braking
will activate when you get closer to the obstacle.
Assistive driving power suppr ession will not activate in the following 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 position is in a position other than
(R.
If the only rear sensors are turned off using the parking sensor system, the assistive
braking will not work when reversing.

Conditions for assistive driving power suppression.
• When the accelerator is no longer depressed.
• When the accelerator is depressed for approximately four seconds.
• When the brake pedal is depressed.
Conditions for assistive braking cancellation.
• A certain amount of time ha s passed since activation.
The system may not operate correctly under the following conditions:
■Examples of obstacles the sonar sensors cannot detect
• Obstacles that do not refl ect 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.
• Obstacles that are not pe rpendicular to the ground.
• Moving objects or obstacles that suddenly enter the road.
■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.
It 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.
