uuAcuraWatchTMuRoad Departure Mitigation System
Continued
Driving
Road Departure Mi tigation 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 st eering torque and alerts
you with rapid vibrations on the steering
wheel, to help you remain within the detected
lane.
2 Customized Features P. 345
As a visual alert, appears on the gauge.
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.
■How the System Works
1Road Departure Mitigation System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Over-reliance 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 Mitigati on 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 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 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. 539
There are times when you may not notice Road
Departure Mitigation functions due to your operation
of the vehicle, or road surface conditions.
The Road Departure Mitiga tion is not activated for
about 15 seconds after the power system is turned on.
