Driving
■Automatic ca ncellation
The beeper sounds and a message appear s on the MID when ACC with LSF is
automatically canceled. Any of these co nditions may cause the ACC with LSF to
automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor behind the emblem gets dirty.
• The vehicle ahead of yo u cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the AC C with LSF range is too close to your
vehicle.
• When the detected vehicle goes out of th e ACC with LSF range while your vehicle
is stationary.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation ca n be also triggered by the following
causes. In these cases, th e electric parking brake will be automatically applied.
• The driver’s seat belt is unfastene d when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The power system is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically
canceled, you can still resu me the prior set speed.
Wait until the condition that caused ACC with LSF to
cancel improves, then press the RES/+/SET/– switch
up.

uuWhen Driving uRoad Departure Mitigation (RDM) System
Driving
Road Departure Mitigation (RDM) System
Alerts and helps to assist you when the sy stem detects a possibility of your vehicle
unintentionally crossing over detected la ne markings and/or leaving the roadway
altogether.
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 steering torque and alerts you
with rapid vibrations on the steering wheel, to
help you remain within the detected lane.
2 Customized Features P. 131, 362
As a visual alert, the Lane Departure
message appears on the MID.
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 wh en you turn the 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.

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 al erts 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 vehicle 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. 122
Do not place objects on the instrument panel.
Objects may reflect on th e windshield and prevent
correct detection of the traffic lanes.
The LKAS only alerts you when lane drift is detected
without a turn signal in use. 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 an d 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. 503
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 475
The LKAS may not function as designed while driving
in frequent stop and go traf fic, or on roads with
sharp curves.
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.

Driving
Blind spot information System
Is designed to detect vehicles in specifie d alert zones adjacent to your vehicle,
particularly in harder to see areas commonly known as “blind spots.”
When the system detects vehicles 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 information System
Important Safety Reminder
Like all assistance systems, blind spot information
system has limitations. Over reliance on blind spot
information system may result in a collision.
The blind spot information system alert indicator 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 betw een your vehicle and the
vehicle you are passing is greater than 6 mph (10
km/h).
•An object not detected by the radar sensors
approaches or passes your vehicle.
•A vehicle running in the adjacent lane is a
motorcycle or other small vehicle.
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.

Driving
Collision Mitigation 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 CMBS
TM is designed to reduce the severity of an
unavoidable collision. It do es not prevent a collision
nor stop the vehicle automati cally. 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. 529
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 475
Be careful not to severely impact the radar sensor
cover.
1 How the system works
Rapid vibrations on the steering wheel alert you
when your vehicle speed is between 19 and 62 mph
(30 and 100 km/h) with an oncoming vehicle
detected in front of you.
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.
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
behind the emblem.
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.
