Driving
Lane Departure Warning (LDW)*
Alerts you when the system determines a possibility of your vehicle unintentionally
crossing over detected lane markings.
If your vehicle is getting too close to detected
left or right side lane markings without a turn
signal activated, LDW will give audible and
visual alerts.
The beeper sounds and the Lane Departure
message appears on the multi-information
display, letting you know that you need to
take appropriate action.
The system begins to search for lane mark ings 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.
■How the System Works
1Lane Departure Warning (LDW)*
Important Safety Reminder
Like all assistance systems, LDW has limitations.
Over-reliance on LDW may result in a collision. It is
always your respons ibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in us e. LDW may not detect all
lane markings or lane departures; a ccuracy will vary
based on weather, speed and lane marker condition.
It is always your responsibility to safely operate the
vehicle and avoid collisions.

uuWhen Driving uLane Keeping Assist System (LKAS)*
302
Driving
Provides assistance to keep the vehicle in the center of the lane. When the vehicle
nears a white or yellow line, steering force of the electric power steering will become
stronger.
When the vehicle enters th e warning area, LKAS alerts you with beeps as well a
warning display.
■Lane Keep Support Function1 Lane Keeping Assist System (LKAS)*
The LKAS may not functi on as designed on while
driving in frequent stop and go traffic, or on roads
with sharp curves.
When it fails to detect lanes, the system will
temporarily be cancelled. When lane is detected,
system will recover automatically.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera

Driving
Blind spot informa tion (BSI) System*
Is designed to detect vehicles in specified alert zones adjacent to your vehicle,
particularly in harder to see areas commonly known as “blind spots.”
When the system detects vehicles approach ing from behind in adjacent lanes, the
appropriate indicator comes on for a few se conds, providing assistance when you
change lanes.
■How the system works
1 Blind spot inform ation (BSI) System*
Important Safety Reminder
Like all assistance systems, BSI has limitations. Over
reliance on BSI may re sult in a collision.
The system is for your convenience only. Even if an
object is within the alert zone, the following
situations may occur.
•The BSI alert indicator may not come on due to
obstruction (splashes, et c.) even without the BLIND
SPOT NOT AVAILABLE/Blind Spot Info Not
Available multi-information display appearing.
•The BSI alert indicator may come on even with the
message appearing.
3WARNING
Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on the blind spot
information system wh en changing lanes.
Always look in your mirrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.
Radar sensors detect a
vehicle in the alert zone
when your vehicle is
moving forward at
between 20 mph (32 km/h)
and 100 mph (160 km/h). Alert zone range
