■Vehicle conditions
• Headlight lenses are dirty or the h eadlights are not properly adjusted.
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• The inside of the windshield is fogged.
• An abnormal tire or wheel condition (inco rrect sizes, varied sizes or construction,
improperly inflated, etc.).
• When tire chains are installed.
• The vehicle is tilted due to a heavy load or suspension modifications.
• The camera temperature gets too high.
• Driving with the parking brake applied.
• When the radar sensor behind the Hond a emblem on the front grille gets dirty.

■Automatic shutoff
The CMBSTM may automatically shut itself off and the safety support indicator
(amber) comes and stays on when:
• You drive off-road or on a mountain ro ad, 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 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 (i ncorrect tire size, flat tire, etc.).
Once the conditions that caused the CMBS
TM to shut off improv e or are addressed
(e.g., cleaning), the system comes back on.

Driving
Low Speed Braking Control*
Using sonar sensors located on the front and r ear 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 depressed 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.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 obstacles, as well as providing assistance
with braking.
If the only rear sensors are turned off using the parking sensor system, the assistive
braking will not work when reversing.

sensors, please refer to the following page.

* P. 571
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 chas sis dynamometer or free
rollers for inspection or when washing the car in
conveyor type car wash machine.
If you put any accessories on or around the rear
sensors, the Low Speed Br aking Control System may
activate if it detects these accessories as an obstacle.
In this case, turn off the rear sensor. 2 Customized Features P. 376Audible Alert

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 correctly under the following conditions:
■Examples of obstacles the sonar sensors cannot detect
• Obstacles that do not reflect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fenc es, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Obstacles that are not perp endicular 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.
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.

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. 570
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 568
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 road and 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 quickly stops in front of you.
Always be prepared to apply the brake
pedal if the conditions 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 or .B
The radar sensor is behind
the Honda emblem on the
front grille.
A front sensor
camera is
located behind
the rearview
mirror.

If you need the radar sensor to be repaired, or
removed, or the front grille is strongly impacted, turn
off the system by pre ssing the button and take
