uuAcuraWatchTMuRoad Departure Mitigation System
Driving
Road Departure Mitigation System
Alerts and helps to assist you when the system 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. 302
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 th e 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 ve hicle 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. 2 Front Sensor Camera P. 481
The Road Departure Mitigati on system may not work
properly or may work im properly under the certain
conditions:
2 Road Departure Mitigation Conditions and
Limitations P. 473
There are times when you may not notice the Road
Departure Mitigation functions due to your operation
of the vehicle, or road surface conditions.

The system may not properly detect lane ma rkings 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 reflec ted 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 interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.
■Road Departure Mitigation Conditions and Limitations1Road Departure Mitigation On and Off
The vehicle stability assist
TM (VSA ®) system, vehicle
stability assistTM (VSA ®) OFF, adaptive cruise control
(ACC) with low speed follow, and safety support
indicators may come on in amber along with a
message in the multi-information display when you
set the power mode to ON after reconnecting a
battery.
Drive a short distance at more than 12 mph (20
km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.

Continued
Driving
Traffic Sign Recognition System
Reminds you of road sign information of the current speed limit your vehicle has just
passed through, showing it on the multi-information display and the head-up
display
*.
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.
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
1Traffic 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 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.
You can select whether the source of the speed limit
information is the front sensor camera or the
navigation system.
You can also turn off speed limit information.

If the system does not detect any traffic signs while you are driving, the image below
may appear.1 Traffic Sign Recognition System
To help reduce the likel ihood 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.
