Honda Sensing

Collision Mitigation Braking System

(CMBS

)

Driving

•

When there is a group of people in front of your vehicle walking together side by
side.

•

Surrounding conditions or belongings of the pedestrian alter the pedestrian’s
shape, preventing the system from recognizing that the person is a pedestrian.

•

When the pedestrian is shorter than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.

•

When a pedestrian blends in with the background.

•

When a pedestrian is bent over or squatting, or when their hands are raised or
they are running.

•

When several pedestrians are walking ahead in a group.

•

When the camera cannot correctly identify that a pedestrian is present due to an
unusual shape (holding luggage, body position, size).

■

Automatic shutoff

The CMBS

may automatically shut itself off and the safety support indicator

(amber) comes and stays on when:

•

The temperature inside the system is high.

•

You drive off-road or on a mountain road, or curved and winding road for an
extended period.

•

An abnormal tire condition is detected (incorrect tire size, flat tire, etc.).

•

The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.

Once the conditions that caused the CMBS

to shut off improve or are addressed

(e.g., cleaning), the system comes back on.

Limitations applicable to pedestrian detection only

Low Speed Braking Control

Continued

Driving

Low Speed Braking Control

Using sonar sensors located on the front and rear bumpers, the vehicle detects if
there is danger of a potential collision with a wall or other obstacle. The system is
designed to alert you when a potential collision is determined, as well as assist in
reducing speed, avoiding collisions, and reducing collision severity.

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.

WARNING

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.

Low Speed Braking Control

466

Driving

The Low Speed Braking Control 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 obstacle, as well as providing
assistance with braking.

If the only rear sensors are turned off using the parking sensor system, the assistive
braking is not working when reversing.

Adaptive Cruise Control (ACC) with Low Speed Follow

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 detected vehicle comes to a stop, can decelerate
and stop your vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follow slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.

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.

■

There is no vehicle ahead

Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your vehicle from traveling at
the set speed, ACC with Low Speed Follow
accelerates your vehicle to the set speed, and
then maintains it.

■

When you depress the accelerator pedal

You can temporarily increase the vehicle speed. In this case, there is no audible or
visual alert even if a vehicle is in the ACC with Low Speed Follow range.
ACC with Low Speed Follow stays on unless you cancel it. Once you release the
accelerator pedal, the system resumes an appropriate speed for keeping the
following interval while a vehicle ahead is within the ACC with Low Speed Follow
range.

When in Operation

Even if the interval between your vehicle and the
vehicle detected ahead is short, ACC with Low Speed
Follow may start accelerating your vehicle under the
following circumstances:

•

The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.

•

A vehicle that cuts in front of you is going faster
than your vehicle, gradually increasing the interval
between the vehicles.

You can also set the system to beep when a vehicle in
front of you comes in and goes out of the ACC with
Low Speed Follow detecting range. A vehicle detect
beep on and off can be selected.
