Driving
Press the LDW button to turn the system on
and off. u The indicator in the button comes on
when the system is on.
■LDW On and Off1Lane Departure Warning Camera (LDW Camera)
Do not place an object on the top of the instrument
panel. It may reflect onto the windshield and prevent
the system from detecting lane lines properly.
To help reduce the likel ihood that high interior
temperatures will cause the camera system to shut
off, when parking, find a sh ady area or face the front
of the vehicle away from the sun.
If you use a reflective sun shade, do not allow it to
cover the camera housing. Covering the camera can
concentrate heat on the camera.
If the Can Not Operate: Camera Too Hot message
appears:
•Use the climate control system to cool down the
interior and, if necessary , the defroster mode when
windows are fogged.
•Start driving the vehicle to lower the windshield
temperature, which cool s down the area around
the LDW camera.

uuWhen Driving uLane Keeping Assist System (LKAS)*
Driving
Lane Keeping Assist System (LKAS)*
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides tactile and visual alerts if the ve hicle 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. 95
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.
The LKAS only alerts you when lane drift is detected
without a turn signal in us e. The LKAS may not detect
all lane markings or lane departures; accuracy will
vary based on weather, speed, and 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. 391
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 359
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 operating the turn signals, the LKAS
alerts activate, and torque is applied to the steering.
■LKAS camera
Monitors the lane
lines
■Tactile and visual alerts
Rapid vibrations on the steering wheel and a warning display alert you that the
vehicle is drifting out of a detected lane.
■Steering input assist
The system applies torque to the
steering to keep the vehicle between
the left and right lane lines. The applied
torque becomes stronger as the vehicle
gets closer to either of the lane lines.

uuWhen Driving uLane Keeping Assist System (LKAS)*
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 the warning area, the LKAS alerts you with slight steering
wheel vibration as well as 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 canceled. When lane is detected,
system will recover automatically.

uuWhen Driving uBlind Spot Information (BSI) System*
Driving
Blind Spot Information (BSI) System*
Is designed to detect vehicl es in specified alert zones adjacent to your vehicle,
particularly in harder to see areas commonly known as “blind spots.”
When the system detects vehi cles approaching 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 result 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 Info Not Available multi-information
display appearing.
•The BSI alert indicator may come on even with the
message appearing.
The BSI alert i ndicator may not come on under the
following conditions:
•A vehicle does not stay in the alert zone for more
than two seconds.
•A vehicle is parked in a side lane.•The speed difference between your vehicle and the
vehicle you are passing is greater than 6 mph (10 km/h).
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 20 mph (32 km/h)
or faster.
Alert zone range
A: Approx. 1.6 ft. (0.5 m)

■Vibration alert on the steering wheel
When a potential collision to an oncoming detected vehicle is determined, the
system alerts you with rapid vibration on th e steering wheel, in addition to visual and
audible alerts.
u Take appropriate action to prevent a co llision (apply the brakes, operate the
steering wheel, etc.).
1 When the system activates
The camera in the CMBS
TM is also designed to detect
pedestrians.
However, this pedestrian detection feature may not
activate or may not detect a pedestrian in front of
your vehicle under certain conditions.
Refer to the ones indicating the pedestrian detection
limitations from the list. 2 CMBS

uuParking Your Vehicle uCross Traffic Monitor*
Driving
The system activates when:
• The power mode is in ON.
• The Cross Traffic Monitor is turned on.
2 Cross Traffic Monitor On and Off P. 425
2 Customized Features P. 262
•The shift lever is in (R.
• Your vehicle is moving at 3 mph (5 km/h) or
lower.
When a vehicle is detected approaching from a rear corner, Cross Traffic Monitor
alerts you with a buzzer and a displayed warning.
The system will not detect a vehicle that approaches from directly behind your
vehicle, nor will it provide alerts about a detected vehicle when it moves directly
behind your vehicle.
The system does not provide alerts for a vehicle that is moving away from your
vehicle, and it may alert for pedestrians, bicycles, or stationary objects.
■How the System Works1 Cross Traffic Monitor*
Cross Traffic Monitor may not detect or may delay
alerting an approaching vehi cle, or may alert without
an approaching vehicle under the following
conditions:
•An obstacle, such as a nother vehicle and a wall,
near your vehicle’s rear bumper, is blocking the
radar sensor’s scope.
•Your vehicle is moving at the speed of about 3 mph
(5 km/h) or higher.
•A vehicle is approaching at the speed other than
between about 6 mph (10 km/h) and 16 mph (25
km/h).
•The system picks up external interference such as
other radar sensors from an other vehicle or strong
radio wave transmitted fr om a facility nearby.
•Either corner of the rear bumper is covered with
snow, ice, mud or dirt.
•When there is bad weather.
•Your vehicle is on an incline.
•Your vehicle is tilted due to a heavy load in the rear.•Your vehicle is reversing towards a wall, a poll, a
vehicle, and so on.
•The rear bumper or the sensors have been
improperly repaired or the rear bumper has been
deformed. Have your vehi cle checked by a dealer.
For proper operation, always keep the rear bumper
corner area clean.
Do not cover the rear bumper corner area with labels
or stickers of any kind.
