Driving
Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)*
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle slows to a stop, decelerates and
stops your vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle's brake
lights will illuminate.1 Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)*
Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always
keep a safe distance between your vehicle and other
vehicles.
3WARNING
Improper use of ACC with LSF can lead to a
crash.
Use ACC with LSF only when driving on
expressways or freeways and in good
weather conditions.
3WARNING
ACC with LSF has limited braking
capability and may not stop your vehicle
in time to avoid a co llision with a vehicle
that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the cond itions require.
When to use
■Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with
LSF range – ACC with LSF operates at speeds up to 90 mph (145 km/h).

uuWhen Driving uRoad Departure Mitigation (RDM) System*
Driving
Road Departure Mitigation (RDM) System*
Alerts and helps to assist you when the system determines a possibility of your
vehicle unintentionally crossing over detected lane markings.
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 st eering torque and alerts
you with rapid vibrations on the steering
wheel, to help you remain within the detected
lane.
2 Customized Features P. 103, 262
As a visual alert, the Lane Departure
message appears on the multi-information
display.
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 when you turn th e 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.

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:

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.

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 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. 413
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 359
1How the system works
Rapid vibrations on the steering wheel alert you
when the 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 radar sensor is
in the front grille.
The camera is
located behind
the rearview
mirror.
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.
When to use
The CMBSTM 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.
