uuWhen Driving uLane Departure Warning (LDW)*
Driving
LDW may not activate or may not recogniz e lanes, and may activate even when
keeping in the middle of a lane, under certa in 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 la ne lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected 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 interior of the front windshield.
■Roadway conditions
• Driving on a snowy or wet roadway (obscured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on a road with temporary lane markings.
• Faint, multiple, or varied lane markings are visible on the roadway due to road
repairs or old lane markings.
• The roadway has merging, split, or crossing lines (e.g., such as at an intersection
or crosswalk).
• The lane markings are extremely narrow, wide, or changing.
• The vehicle in front of you is driving near the lane lines.
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving over bumps.

uuWhen Driving uRoad Departure Mitigation (RDM) System*
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.
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 (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.

* P. 353
The RDM system may not wo rk properly or may work
improperly under the certain conditions: 2 RDM Conditions and Limitations P. 381
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.

The system becomes ready to start sear ching for lane markings when all the
following conditions are met:
• The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.
• The vehicle is not accelera ting or braking, and the steering wheel is not being
turned.
• The system makes a determination that th e driver is not actively accelerating,
braking or steering.
■How the System Activates1 How the System Activates
The RDM system may automa tically shut off and the
indicator comes and stays on.
2 Indicators P. 87
RDM system function can be impacted when the
vehicle is:
•Not driven within a traffic lane.
•Driven on the inside edge of a curve, or outside of
a lane.
•Driven in a narrow lane.

Driving
Lane Keeping Assist System (LKAS)*
Provides steering input to help keep the vehicle in the middle of a detected lane and
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.
LKAS only alerts you when lane drift is detected
without a turn signal in use. LKAS may not detect all
lane markings or lane departures; a ccuracy will vary
based on weather, speed, an d lane marker condition.
It is always your responsibility to safely operate the
vehicle and 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. 389
LKAS may not function as designed on while driving
in frequent stop and go traf fic, or on roads with
sharp curves.
