Road Departure Mitigation System

Driving

The system may not properly detect lane markings and the position of your vehicle 
under certain conditions. Some examples of these conditions are listed below.

■

Environmental conditions

•

Driving in bad weather (rain, fog, snow, etc.).

•

Sudden changes between light and dark, such as an entrance or exit of a tunnel.

•

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.

•

Reflections on the interior of the windscreen.

•

Driving at night or in a dark condition such as a tunnel.

•

The outer edge of the pavement is bordered by objects, material etc. other than 
grass or gravel.

Lead Car Departure Notification System

Driving

Lead Car Departure Notification System

Informs you with visual and audible alerts when your vehicle is stopped even though 
the vehicle ahead of you has started moving.

The system detects a stopped vehicle in front of you, on the condition that the 
vehicles are within 10 m (32 ft.) of each other and both vehicles have been stopped 
for a period of time. When the detected vehicle moves but yours does not, the 
system will activate.

The system will work when the brake pedal is depressed, the brake hold function of 
the automatic brake hold system is in operation, or ACC with Low Speed Follow is 
in operation.

WARNING

Lead Car Departure Notification System is 
an supplemental system that provides 
driving assistance. It is not a system that 
informs you if it is safe to start driving.

Improper use of this system may lead to a 
collision.

Always visually confirm the safety of your 
surroundings before driving the vehicle 
and maintain a safe following-interval 
when driving.

Traffic Sign Recognition System

Driving

Traffic Sign Recognition System

Reminds you of road sign information, such as the current speed limit and that 
overtaking is prohibited, your vehicle has just passed through, showing it on the 
gauge.

When the camera located behind the rearview mirror captures traffic signs while 
driving, the system displays the ones that are recognised as designated for your 
vehicle. The sign icon will be displayed until the vehicle reaches a predetermined 
time and distance.

The sign icon also may switch to another one, or disappear when:

•

The end of speed limit or other designated limit is detected.

•

Your vehicle enters/exists motorway or highway.

•

You make a turn with a turn signal at an intersection.

■

How the System Works

1

Traffic Sign Recognition System

The system is designed to detect signs that follow the 
Vienna Convention standards. Not all signs may be 
displayed, but any signs posted on roadsides should 
not be ignored. The system does not work on the 
designated traffic signs of all the countries you travel, 
nor in all situations.
Do not rely too much on the system. Always drive at 
speeds appropriate for the road conditions.

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

If the system does not detect any traffic signs while you are driving, the image below

Traffic Sign Recognition System

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.

The unit for speed limits (mph or km/h) varies from

If your vehicle exceeds the detected speed limit, an 
icon representing the speed limit sign for the current 
area will blink in the display. 

The system's ability to accurately notify the driver of 
the speed limit is dependent on certain conditions 
such as the units displayed on the traffic sign as well 
as the speed and direction of travel of the vehicle. In 
some cases, the system may display false warnings or 
other inaccurate information.

Front Sensor Camera

The camera, used in systems such as Lane Keeping Assist System (LKAS), Road 
Departure Mitigation System, Adaptive Cruise Control (ACC) with Low Speed 
Follow, Traffic Sign Recognition System, Lead Car Departure Notification System, 
and Collision Mitigation Braking System (CMBS), 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 to 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

Camera Location and Handling Tips

1

Front Sensor Camera

Never apply a film or attach any objects to the 
windscreen, the bonnet, or the front grille that could 
obstruct the camera’s field of vision and cause the 
system to operate abnormally.
Scratches, nicks, and other damage to the 
windscreen within the camera’s field of vision can 
cause the system to operate abnormally. If this 
occurs, we recommend that you replace the 
windscreen with a genuine Honda replacement 
windscreen. Making even minor repairs within the 
camera’s field of vision or installing an aftermarket 
replacement windscreen may also cause the system 
to operate abnormally.
After replacing the windscreen, 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 windscreen and prevent 
the system from detecting lane lines properly.

If the

•

Use the climate control system to cool down the 
interior and, if necessary, also use demister mode 
with the air flow directed towards the camera.

•

Start driving the vehicle to lower the windscreen 
temperature, which cools down the area around 
the camera.

If the 

 message appears:

•

Park your vehicle in a safe place, and clean the 
windscreen. If the message does not disappear 
after you have cleaned the windscreen and driven 
for a while, have your vehicle checked by a dealer.

Avoid strong impacts to the radar sensor cover.

For the CMBS to work properly:

Always keep the radar sensor cover clean.

Never use chemical solvents or polishing powder for 
cleaning the sensor cover. Clean it with water or a 
mild detergent.

Do not put a sticker on the radar sensor cover or 
replace the radar sensor cover.

If you need the radar sensor to be repaired, or 
removed, or the radar sensor cover is strongly 
impacted, turn off the system by using the safety 
support switch and take your vehicle to a dealer.

If the vehicle is involved in any of the following 
situations, the radar sensor may not work properly.

•

Your vehicle is involved in a frontal collision

•

Your vehicle drives through deep water or is 
submerged in deep water

•

Your vehicle strongly strikes a bump, curb, chock,
