The LKAS resumes when the wipers stop 
or operate at low speed.

• Decrease the vehicle speed to about 40 mph 

(64 km/h) or less.

u

Increasing the vehicle speed to about 
45 mph (72 km/h) or more resumes the 
LKAS.

• Depress the brake pedal.

u

The LKAS resumes and starts detecting 
the lane lines again once you release the 
brake pedal.

■

The LKAS may automatically be suspended when:

• The system fails to detect lane lines.
• The steering wheel is quickly turned.
• You fail to steer the vehicle.
• Driving through a sharp curve.
• Driving at a speed in excess of approximately 90 mph (145 km/h).
Once these conditions no longer exist, the LKAS automatically resumes.

When the LKAS is suspended, 
the lane lines on the driver 
information interface change to

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.

2 Customized Features P. 153, 359, 366

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.

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.

The RDM system may not work properly or may work 
improperly under the certain conditions:

2 RDM Conditions and Limitations P. 520

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 LSF 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.

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

1

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.

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.

If the Some Driver Assist Systems Cannot 
Operate: Camera Temperature Too High message 
appears, the traffic sign recognition system does not 
work, and 

 will be displayed.

•

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

•

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

If the Some Driver Assist Systems Cannot 
Operate: Clean Front Windshield message 
appears, the traffic sign recognition system does not 
work, and 

 will be displayed.

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