uuWhen Driving uLane Departure Warning (LDW)*
Continued
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.

camera equipped with this system. 2 Front Sensor Camera

Continued
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. 91
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. 307
Beeps and a warning display alert you
that the vehicle is drifting out of a
detected lane.
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 operat ing the turn signals, the LKAS alerts
activate, and torque is applied to the steering.

uuWhen Driving uBlind spot information (BSI) System*
Continued
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
A: Approx. 1.6 ft. (0.5 m)

uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)*
Driving
Collision Mitigati on Braking SystemTM (CMBSTM)*
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when a
potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)*
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It does not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions:
2 CMBS
TM Conditions and Limitations P. 326
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 282
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you. The radar sensor is
in the front grille.
The CMBS
TM activates when:●The speed difference between your vehicle and a vehicle or pedestrian
detected in front of you becomes about 3 mph (5 km/h) and over with a chance
of a collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you. The camera is
located behind the
rearview mirror.
