Driving
Road Departure Mitigation (RDM) System
Alerts and helps to assist you when the system determines a possibility of your
vehicle unintentionally crossing over detected lane markings.
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. 113, 283
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 wh en you turn the steering wheel to avoid
crossing over detected lane markings.
If the system operates several times with out 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 la ne markings or lane or
roadway departures; accu racy will vary based on
weather, speed and lane marker condition. It is
always your responsibilit y to safely operate the
vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.
2 Front Sensor Camera P. 381
The RDM system may not wo rk properly or may work
improperly under the certain conditions: 2 RDM Conditions and Limitations P. 399
There are times when you may not notice RDM
functions due to your opera tion of the vehicle, or
road surface conditions. If the Lane Departure
message displays repeated ly and you do not apply
responsive actions, the sy stem beeps and cancels
RDM functions.
