Continued
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 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. 126, 257
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.

The RDM system may not wo rk properly or may work
improperly under the certain conditions: 2 RDM Conditions and Limitations P. 380
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.

provides audible and visual alerts if the vehicle 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 Multi-Information Display Warning and
Information Messages P. 113
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.

uuWhen Driving uAgile Handling Assist
Driving
Agile Handling Assist
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehi cle’s stability and performance during
cornering.
Precision All-Wheel SteerTM (P-AWS® ) System*
Monitors your vehicle’s response to road conditions while you are driving. In
response to current driving conditions, the system automatically makes slight
adjustment to the relative rear wheel toe settings to help enhance vehicle control
and stability.
1 Agile Handling Assist
The agile handling assist cannot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not
activate.
You may hear a sound coming from the engine
compartment while the agile handling assist is
activated. This is normal.
1 Precision All-Wheel SteerTM (P-AWS ®) System*
The Precision All-Wheel SteerTM (P-AWS ®) system
cannot enhance vehicle cont rol and stability in all
driving situations. You still need to drive and corner
at speeds appropriate for the conditions and always
leave a sufficient margin of safety.
The toe setting of the rear wheels may get stuck in a
non-centered se tting if the system malfunctions
while driving. This can caus e the vehicle to pull to a
side even as you keep the steering wheel in the
center position. If this occurs, the system
automatically limits the vehicle speed to a maximum
of 50 mph (80 km/h). Reduce your speed and be
extra cautious, as handling may be difficult. Go to a
dealer immediately.
