PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the radar sensor
*Adetects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance.
The system automatically controls the
throttle and applies the brakes (up to
approximately 40% of vehicle braking power) if necessary.
The detection range of the sensor is
approximately 650 ft (200 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.
. The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the
system in city traffic or congested areas.
. This system will not adapt automatically
to road conditions. This system should
be used in evenly flowing traffic. Do not
use the system on roads with sharp
curves, or on icy roads, in heavy rain or
in fog.
The radar sensor will not detect under
most conditions:
.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
distance control function, never rely
solely on the Intelligent Cruise Control
(ICC) system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Decelerate the vehicle speed by depres-
sing the brake pedal, depending on the
distance to the vehicle ahead and the
surrounding circumstances in order to
maintain a safe distance between vehi-
cles.
. 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 and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not detect the vehicle in

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 DCA system. Read and
understand the Owner’s Manual thor-
oughly 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 DCA system
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.

does not correct careless, inattentive or
absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by
depressing the brake pedal, depending
on the distance to the vehicle ahead and
the surrounding 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
conditions. To avoid accidents, never use
the DCA system under the following
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 rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (frequentbraking may result in overheating
the brakes)
—On repeated uphill and downhillroads .
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 distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.

DCA SYSTEM 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
behind the lower grille of the front bumper
to detect vehicles traveling ahead.
The following are some conditions in which
the sensor cannot detect the signals:
. When the snow or road spray from
traveling 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 automati-
cally check the sensor’s operation. When
the sensor area of the front bumper is
covered with dirt or is obstructed, the
system will automatically be canceled. If
the sensor area is covered with ice, a
transparent or translucent vinyl bag, etc.,
the DCA system may not detect them. In
these instances, the DCA system may not
be able to decelerate the vehicle properly.
Be sure to check and clean the sensor area
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 approxi-
mately 40% 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 decelerate 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” (P.5-86).
This system only brakes and moves the
accelerator 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.

SSD0253
When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
sensor may detect vehicles 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 traveling position in the lane,
etc.) or vehicle condition.If this occurs, the
system may warn you by blinking the
system indicator and sounding the chime
unexpectedly. You will have to manually
control the proper distance away from the vehicle traveling ahead.

NOTE:
The approach warning chime may sound
and the driver assist system forward
indicator (orange) may blink when the
radar sensor detects objects on the side of
the vehicle
*Aor on the side of the road
*A. This may cause the DCA system to
decelerate or accelerate the vehicle. The
radar sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads or when
entering or exiting a curve. In these cases
you will have to manually control the
proper distance ahead of your vehicle.
Also, the sensor sensitivity can be affected by vehicle operation (steering maneuver or
driving position in the lane) or traffic or
vehicle condition (for example, if a vehicle
is being driven with some damage).
Automatic cancellation
Condition A:
Under the following conditions, the Dis-
tance Control Assist (DCA) system is
automatically canceled. The chime will
sound and the
“currently unavailable”
warning message will appear in the vehicle
information display. The system will not be
