Road Departure Mi tigation System
Alerts and helps assist you when the system detects a possibility of your vehicle
crossing over detected lane markings, or approaching the outer edge of the
pavement (into grass or gravel bord er) or a detected oncoming vehicle.
The front wide view camera behind the
rearview mirror monitors left and right lane
markings in white or yellow, the outer edge of
the pavement (bordered by grass or gravel) or
a detected oncoming vehicles.
If your vehicle approach es any detected lane
markings, the outer edge of the pavement
(bordered by grass or gravel) or a detected
oncoming vehicles when the turn signals have
not been engaged, the system activates. u
If the system cannot detect lane markings
(in white or yellow), no assistance will be
provided to avoid approaching oncoming
vehicles. In addition to a visual alert, the
system assists with steering and alerts you
with rapid steering wheel vibrations to help
you remain within the detected lane.

■How the System Works
1Road Departure Mitigation System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Overreliance 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 Mitiga tion system alerts you
when the system detects that you are approaching
the outer edge of the paveme nt (into grass or gravel
border), an oncoming vehicle, or drifting into another
lane without using a turn signal.
The Road Departure Mitigation system may not detect
all lane markings or ever y instance of lane drift.
The Road Departure Miti gation system may not
detect that you are approa ching the outer edge of
the pavement (bordered by grass or gravel) or an
oncoming vehicle.
The Road Departure Mitiga tion system may not be
able to assist you depend ing on weather, speed or
road conditions.
The Road Departure Mitigation system is not activated
for about 15 seconds af ter the engine starts.
You can read about handling information for the
camera equipped with this system. 2 Front Wide View Camera P. 653

Driving
The system may not properly detect lane ma rkings (in white or yellow), the outer
edge of the pavement (into grass or grav el border) or an oncoming vehicle under
certain conditions. Some ex amples of these conditions are listed below.
■Environmental conditions
• There is little contrast between lane lines and the roadway surface.
• Driving in bad weather (rain, fog, snow, etc.).
• Driving on a snowy or wet roadway.
• Driving into low sunlight (e.g., at dawn or dusk).
• Shadows of adjacent object s (trees, buildings, guard rails, vehicles, etc.) are
parallel to white (or yellow) lines.
• Sudden changes between light and dark, such as the entrance or exit of a tunnel
or the shadows of trees, buildings, etc.
• Strong light is reflec ted onto the roadway.
• Driving at night or in a dark place such as a tunnel (due to low-light conditions,
lane lines, the road surface, or onco ming vehicles may not be illuminated).
• The distance between your vehicle and the vehicle ahead of you is too short, and
lane lines and the road surface are not visible.
• The outer edge of the road is bordered by objects, materials, etc. other than grass
or gravel.
