Driving

Front Sensor Camera

*

The camera, used in systems such as LKAS, RDM, ACC, and CMBS

TM

, is designed to 

detect an object that triggers any of the systems to operate its functions.

This camera is located behind the rearview 
mirror.

To help reduce the likelihood that high interior 
temperatures will cause the camera’s sensing 
system to shut off, when parking, find a shady 
area or face the front of the vehicle away from 
the sun. If you use a reflective sun shade, do 
not allow it to cover the camera housing. 
Covering the camera can concentrate heat on 
it.

■

Camera Location and Handling Tips

1

Front Sensor Camera

*

Never apply a film or attach any objects to 
windshield, the hood, or the front grill that could 
obstruct the camera’s field of vision and cause the 
system to operate abnormally.
Scratches, nicks, and other damage to the windshield 
within the camera’s field of vision can cause the 
system to operate abnormally. If this occurs, we 
recommend that you replace the windshield with a 
genuine Honda replacement windshield. Making 
even minor repairs within the camera’s field of vision 
or installing an aftermarket replacement windshield 
may also cause the system to operate abnormally.
After replacing the windshield, have a dealer 
recalibrate the camera. Proper calibration of the 
camera is necessary for the system to operate 
properly.

Do not place an object on the top of the instrument 
panel. It may reflect onto the windshield and prevent 
the system from detecting lane lines properly.

Road Departure Mitigation (RDM) System

*

Driving

Road Departure Mitigation (RDM) System

*

Alerts and helps to assist you when the system detects a possibility of your vehicle 
unintentionally crossing over detected lane markings and/or leaving the roadway 
altogether.

The front camera behind the rearview mirror 
monitors left and right lane markings (in white 
or yellow). If your vehicle is getting too close to 
detected lane markings without a turn signal 
activated, the system, in addition to a visual 
alert, applies steering torque and alerts you 
with rapid vibrations on the steering wheel, to 
help you remain within the detected lane.

As a visual alert, the Lane Departure 
message appears on the multi-information 
display.

If the system determines that its steering input 
is insufficient to keep your vehicle on the 
roadway, it may apply braking.

u

Braking is applied only when the lane 
markings are solid continuous lines.

The system cancels assisting operations when you turn the steering wheel to avoid 
crossing over detected lane markings.

If the system operates several times without detecting driver response, the system 
beeps to alert you.

How the System Works

1

Road Departure Mitigation (RDM) System

*

Important Safety Reminder
Like all assistance systems, the RDM system has 
limitations.
Over-reliance on the RDM system may result in a 
collision. It is always your responsibility to keep the 
vehicle within your driving lane.

The RDM system only alerts you when lane drift is 
detected without a turn signal in use. The RDM 
system may not detect all lane markings or lane or 
roadway departures; accuracy will vary based on 
weather, speed and lane marker condition. It is 
always your responsibility to safely operate the 
vehicle and avoid collisions.

You can read about handling information for the 
camera equipped with this system.

Driving

The system becomes ready to start searching for lane markings when all the 
following conditions are met:
• The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.
• The system makes a determination that the driver is not actively accelerating, 

braking or steering.

• There is little contrast between lane lines and the roadway surface.
• 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.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.

detected ahead of yours, without you having to keep your foot on the brake or the 
accelerator.

Adaptive Cruise Control (ACC)

*

Important Reminder
As with any system, there are limits to ACC. Use the 
brake pedal whenever necessary, and always keep a 
safe interval between your vehicle and other vehicles.

Be careful not to have the radar sensor cover strongly 
impacted.

3

WARNING

Improper use of ACC can lead to a crash.

Use ACC only when traveling on open 
highways in good weather.

3

WARNING

ACC has limited braking capability.

When your vehicle speed drops below 22 
mph, ACC will automatically cancel and no 
longer will apply your vehicle’s brakes. 

Always be prepared to apply the brake 
pedal when conditions require.

When the MAIN button is pressed, both ACC and 
the Lane Keeping Assist System (LKAS) are either 
turned on or off.

ACC may not work properly under certain conditions.

2 ACC Conditions and Limitations P. 462

When not using ACC: Turn off adaptive cruise by 
pressing the MAIN button. This also will turn off the 
Lane Keeping Assist System (LKAS).

Do not use ACC under the following conditions:

•

On roads with heavy traffic or while driving in 
continuous stop and go traffic.

•

On roads with sharp turns.

•

On roads with steep downhill sections, as the set 
vehicle speed can be exceeded by coasting. In such 
cases, ACC will not apply the brakes to maintain 
the set speed.

•

On roads with toll collection facilities or other 
objects between lanes of traffic, or in parking 
areas, or facilities with drive through access.

■

Press the MAIN button on 
the steering wheel.

ACC (green) is on in the 
multi-information display.

There is a vehicle ahead

ACC monitors if a vehicle ahead of you enters the ACC range. If a vehicle is detected 
doing so, the ACC system maintains or decelerates your vehicle’s set speed in order 
to keep the vehicle’s set following interval from the vehicle ahead.

2 To Set or Change Following Interval P. 465

When a vehicle whose speed is slower than 
your set speed is detected in front of you, your 
vehicle starts to slow down.

■

When in Operation

When in Operation

If the vehicle ahead of you slows down abruptly, or if 
another vehicle cuts in front of you, the beeper 
sounds, a message appears on the multi-information 
display.
Depress the brake pedal, and keep an appropriate 
interval from the vehicle ahead.

Even if the interval between your vehicle and the 
vehicle ahead is short, ACC 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 
detecting range. Change the ACC Forward Vehicle 
Detect Beep setting.

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 accelerates your vehicle to 
the set speed, and then maintains it.

■

When you depress the accelerator pedal

You can temporarily increase the vehicle speed.
ACC stays on unless you cancel it. Once you release the accelerator pedal, the 
system resumes the set speed or a sufficient speed to keep the following interval.

When you depress the accelerator pedal

While the accelerator pedal is depressed, the system 
does not apply the brakes to keep the following 
interval, as well as the BRAKE message on the multi-

unusual behavior of the system (e.g., the warning 
message appears too frequently).

If the front of the vehicle is impacted in any of the
