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 vehicl e 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. 280
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 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.

uuWhen Driving uLane Keeping Assist System (LKAS)
Driving
Lane Keeping Assist System (LKAS)
Provides steering input to help keep the vehicle in the middle of a detected lane and 
provides tactile and visual alerts if the ve hicle is detected drifting out of its lane.1Lane Keeping Assist System (LKAS)
Important Safety Reminders
The LKAS is for your convenience only. It is not a 
substitute for your vehicl e control. The system does 
not work if you take y our hands off the steering 
wheel or fail to steer the vehicle. 2 Driver Information Interface Warning and 
Information Messages  P. 112
Do not place objects on the instrument panel. 
Objects may reflect on th e front windshield and 
prevent correct detectio n of the traffic lanes.
The LKAS only alerts you when lane drift is detected 
without a turn signal in us e. The LKAS may not detect 
all lane markings or lane  departures; accuracy will 
vary based on weather,  speed, and lane marker 
condition. It is always your responsibility to safely 
operate the vehicle an d avoid collisions.
The LKAS is convenient when it is used on freeways.
The LKAS may not work  properly or may work 
improperly under the certain conditions: 2 LKAS Conditions and Limitations  P. 393
You can read about handling information for the 
camera equipped with this system. 2 Front Sensor Camera  P. 367
When you operate the turn signals to chan ge lanes, the system is suspended, and 
resumes after the signals are off.
()  If you make a lane change without operating the turn signals, the LKAS 
alerts activate, and torque  is applied to the steering.
■LKAS camera
Monitors the lane 
lines■Tactile and visual alerts
Rapid vibrations on the steering wheel 
and a warning display alert you that 
the vehicle is drifting out of a 
detected lane.
■Steering input assist
The system applies torque to the steering to keep the vehicle between the left 
and right lane lines. The applied torque  becomes stronger as the vehicle gets 
closer to either of the lane lines.
