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.

Customized Features

P. 351

As a visual alert, the

Lane Departure

message appears on the driver information
interface.

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

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

Road Departure Mitigation (RDM) System

Important Safety Reminder

Like all assistance systems, the RDM system has
limitations.
Overreliance 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.

There are times when you may not notice RDM
functions due to your operation of the vehicle, or
road surface conditions.

In the following case, a beeper sounds, a message
related to the ACC with Low Speed Follow appears
on the driver information interface, and the braking
function controlled by the RDM system is canceled.

•

The vehicle has repeatedly applied the brakes to
maintain the set speed (for example, you are
descending a long slope).

Traffic Sign Recognition System

Driving

Traffic Sign Recognition System

Reminds you of road sign information, such as the current speed limit, your vehicle
has just passed through, showing it on the driver information interface and the
head-up display

When the camera located behind the rearview mirror captures traffic signs while
driving, the system displays the ones that are recognized 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 other designated limit is detected.

•

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

■

How the System Works

Traffic Sign Recognition System

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
windshield 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.

Front Sensor Camera

Driving

Front Sensor Camera

The camera, used in systems such as Lane Keeping Assist System, Road Departure
Mitigation system, Adaptive Cruise Control with Low Speed Follow, Collision
Mitigation Braking System

and traffic sign recognition system, is designed to

detect an object that triggers any of the systems to operate their 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

Front Sensor Camera

Never apply a film or attach any objects to the
windshield, the hood, 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 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.

•

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

If the

Radar Sensor

The radar sensor is at the lower part of the
front bumper.

•

Do not change the position of the radar
sensor or any of the surrounding parts.

•

Do not apply paint, stickers, or attach non-
genuine accessories to the front part of the
radar sensor or the surrounding area. Be
particularly careful that any custom license
plate frame or other accessory does not
block any part of the radar beam path (see
adjacent illustration).

Radar Sensor

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.

Brake System

Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manually or automatically release it.

■

To apply

The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the power mode is in.

Pull the electric parking brake switch up gently
and securely.

The indicator in the switch comes on.

The parking brake and brake system
indicator (red) comes on.

■

To release

The power mode must be in ON in order to
release the electric parking brake.

Depress the brake pedal.

Press the electric parking brake switch.

The indicator in the switch goes off.

The parking brake and brake system
indicator (red) goes off.

Manually releasing the parking brake using
the switch helps your vehicle start slowly and
smoothly when facing downhill on steep hills.

Parking Brake

Braking

When you depress the brake pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.

Parking Brake

You may hear the electric parking brake system
motor operating from the rear wheel area when you
apply or release the parking brake. This is normal.

The brake pedal may slightly move due to the electric
parking brake system operation when you apply or
release the parking brake. This is normal.

You cannot apply or release the parking brake if the
battery goes dead.
