uuAcuraWatchTMuRoad Departure Mitigation System
Driving
Road Departure Mitigation System
Alerts and helps to assist you when the sy stem detects a possibility of your vehicle
unintentionally crossing over detected la ne 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. 359
As a visual alert, the Lane Departure
message appears on the multi-information
display.
If the system determines that its steering i nput 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 wh en 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 System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Overreliance on the Road Departure Mitigation
system may result in a collision. It is always your
responsibility to keep the vehicle within your driving
lane.
The Road Departure Mitigation system only alerts you
when lane drift is detected without a turn signal in
use. The Road Departure Mitigation system may not
detect all lane markings or lane or roadway
departures; accuracy will vary based on weather,
speed and lane marker condi tion. It is always your
responsibility to sa fely operate the vehicle and avoid
collisions.
You can read about handling information for the
camera equipped with this system.

Driving
Traffic Sign Recognition System
Reminds you of road sign information of th e current speed limit your vehicle has just
passed through, showing it on the multi-information display and the head-up
display
*.
1 Traffic Sign Recognition System
Not all signs may be displa yed, 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 fo r the road conditions.
Never apply a film or attach any objects to the
windshield that could obstruc t the camera’s field of
vision and cause the system to operate abnormally.
Scratches, nicks, and othe r 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 Acura replacement windshield. Making even
minor repairs within the ca mera’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.
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.

Driving
Shows the current speed limit based on either information compiled through the
navigation system* or speed limit signs captured by the front sensor camera. 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.
If the system does not detect any traffic signs while you are driving, the sign icon will
not be displayed.
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 Works1Traffic Sign Recognition System

information is the front sensor camera or the

Continued
Driving
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, and Collision Mitigation Braking System
TM
(CMBSTM), 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
1 Front Sensor Camera
Never apply a film or attach any objects to the
windshield, the hood, or th e front grille that could
obstruct the camera’s fiel d of vision and cause the
system to operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s fiel d of vision can cause the
system to operate abnormall y. If this occurs, we
recommend that you replac e the windshield with a
genuine Acura replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarke t replacement windshield
may also cause the system to operate abnormally.
After replacing the winds hield, have a dealer
recalibrate the camera. Pr oper 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.

■The sensor location and range
1 Parking Sensor System*
Even when the system is on, always confirm if there is
no obstacle near your ve hicle before parking.
The system may not work properly when:
•The sensors are covered with snow, ice, mud, or

•There is something nearby that emits ultrasonic
waves or high frequency sounds.
•Driving in bad weather (rain, fog, snow, etc.).
•Any accessories have been put on or around the
sensors.
The system may not de tect these obstacles:
•Thin or low objects.•Sonic-absorptive materials, such as snow, cotton,
or sponge.
•Objects directly under the bumper.
The system may falsely de tect obstacles in the
following situations:
•The vehicle is on uneven su rface, such as grass,
bumps, or a hill.
•When close to other vehicl es with sonar sensors or
