PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
The ICC system with the preview function iden-
tifies the need to apply emergency braking by
sensing the vehicle ahead in the same lane and
the distance to the vehicle ahead and relative
speed from it, it applies the brake pre-pressure
before the driver depresses the brake pedal and
helps improve brake response by reducing
pedal free play.
For more details, see “BRAKE ASSIST” later in
this section.The Distance Control Assist (DCA) system
brakes and moves the accelerator pedal upward
according to the distance from and the relative
speed of the vehicle ahead to help assist the
driver to maintain a following distance.
WARNING
●
Always drive carefully and attentively when
using the Distance Control Assist system.
Read and understand the Owner’s Manual
thoroughly before using the DCA system. To
avoid serious injury or death, do not rely on
the system to prevent accidents or to control
the vehicle’s speed in emergency situations.
Do not use the Distance Control Assist sys-
tem except in appropriate road and traffic
conditions.
● If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within the
limitations of the system. The system will
cancel once it judges that the vehicle has
come to a standstill with a warning chime. To
prevent the vehicle from moving, the driver
must depress the brake pedal.
● The DCA system will not apply brake control
while the driver’s foot is on the accelerator
pedal.
PRECAUTIONS ON DISTANCE CONTROL
ASSIST SYSTEM
The system is intended to assist the driver to
keep a following distance from the vehicle
ahead traveling in the same lane and direction.
If the distance sensor
Adetects a slower
moving vehicle ahead, the system will reduce
the vehicle speed to help assist the driver to
maintain a following distance.
The system automatically controls the throttle
and applies the brakes (up to 25% of vehicle
braking power) if necessary.
The detection range of the sensor is approxi-
mately 390 ft (120 m) ahead.

WARNING
●This system is only an aid to assist the driver
and is not a collision warning or avoidance
device. It is the driver’s responsibility to stay
alert, drive safely and be in control of the
vehicle at all times.
● This system will not adapt automatically to
road conditions. Do not use the system on
roads with sharp curves, or on icy roads, in
heavy rain or in fog.
The distance sensor will not detect the follow-
ing objects:
● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane
● Motorcycles traveling offset in the travel
lane
WARNING
● As there is a performance limit to the dis-
tance control function, never rely solely on
the Distance Control Assist system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances in order to maintain
a safe distance between vehicles.
● The system may not detect the vehicle in
front of you in certain road or weather condi-
tions. To avoid accidents, never use the Dis-
tance Control Assist system under the fol-
lowing conditions:
– On roads with sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor – On steep downhill roads (frequent brak-
ing may result in overheating the brakes)
– On repeated uphill and downhill roads
● Do not use the Distance Control Assist sys-
tem if you are towing a trailer. The system
may not detect a vehicle ahead.
● In some road or traffic conditions, a vehicle
or object can unexpectedly come into the
sensor detection zone and cause automatic
braking. You may need to control the dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the DCA system when it is not recommended
in this section.

DISTANCE CONTROL ASSIST
OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually decelerate to
maintain the proper following distance. The
Distance Control Assist (DCA) system may not
be able to decelerate the vehicle under some
circumstances.
The DCA system uses a sensor
Alocated on
the front of the vehicle to detect vehicles trav-
eling ahead. The sensor generally detects the
signals returned from the reflectors on a vehicle
ahead. Therefore, if the sensor cannot detect
the reflector on the vehicle ahead, the DCA
system may not operate. The following are some conditions in which the
sensor cannot detect the signals:
●
When the reflector of the vehicle ahead is
positioned high on the vehicle (trailer, etc.)
● When the reflector on the vehicle ahead is
missing, damaged or covered
● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When the snow or road spray from traveling
vehicles reduces the sensor’s visibility
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility
● When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the sensor
is covered with dirt or is obstructed, the system
will automatically be canceled. If the sensor is
covered with ice, a transparent or translucent
vinyl bag, etc., the DCA system may not detect
them. In these instances, the Distance Control
Assist (DCA) system may not be able to decel-
erate the vehicle properly. Be sure to check and
clean the sensor regularly. The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as
necessary and if the vehicle ahead comes to a
stop, the vehicle decelerates to a standstill.
However, the DCA system can only apply up to
25% of the vehicles total braking power. If a
vehicle moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the DCA system cannot deceler-
ate the vehicle quickly enough. If this occurs,
the DCA system will sound a warning chime and
blink the system display to notify the driver to
take necessary action.
See “Approach warning” later in this section.
This system only brakes and moves the accel-
erator pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.
The DCA system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead.

The detection zone of the sensor is limited. A
vehicle ahead must be in the detection zone for
the system to operate.A vehicle ahead may move outside of the de-
tection zone due to its position within the same
lane of travel. Motorcycles may not be detected
in the same lane ahead if they are traveling
offset from the centerline of the lane. A vehicle
that is entering the lane ahead may not be
detected until the vehicle has completely
moved into the lane.
If this occurs, the system
may warn you by blinking the system indicator
and sounding the chime. The driver may have to
manually control the proper distance away from
vehicle traveling ahead.

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the sensor may detect ve-
hicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may
cause the system to work inappropriately.The detection of vehicles may also be affected
by vehicle operation (steering maneuver or trav-
eling position in the lane, etc.) or vehicle con-
dition.
If this occurs, the system may warn you
by blinking the system indicator and sounding
the chime unexpectedly. You will have to manu-
ally control the proper distance away from the
vehicle traveling ahead.

WARNING
The Distance Control Assist system automati-
cally decelerates your vehicle to help assist the
driver to maintain a following distance from the
vehicle ahead. Manually brake when decelera-
tion is required to maintain a safe distance
upon sudden braking by the vehicle ahead or
when a vehicle suddenly appears in front of
you. Always stay alert when using the DCA
system.The Distance Control Assist (DCA) system helps
assist the driver to keep a following distance to
the vehicle ahead by braking and moving the
accelerator pedal upward in the normal driving
condition.
When a vehicle is detected ahead :
The vehicle ahead detection indicator comes
on.
When vehicle approaches a vehicle ahead :
●
If the driver’s foot is not on the accelerator
pedal, the system activates the brakes to
decelerate smoothly as necessary. If the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill within the limita-
tions of the system.
● If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward to assist the driver to release
the accelerator pedal.
When brake operation by driver is required :
The system alerts the driver by a warning chime
and blinking the vehicle ahead detection indi-
cator. If the driver’s foot is on the accelerator
pedal after the warning, the system moves the
accelerator pedal upward to assist the driver to
switch to the brake pedal.
