The DCA system is designed to automatically
check the sensor’s operation. When the front
bumper area around the distance sensor is
covered with dirt or is obstructed, the system
will automatically cancel. If the front bumper
area of the distance sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the DCA system may not detect them. In
these instances, the vehicle-to-vehicle dis-
tance control mode may not cancel and may
not be able to maintain the selected following
distance from the vehicle ahead. Be sure to
check and clean the front bumper area
around the distance 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 stand-
still. However, the DCA system can only ap-
ply up to 40% of the vehicle’s total braking
power. If a vehicle moves into the traveling
lane ahead or if a vehicle traveling ahead rapidly decelerates, the distance between ve-
hicles 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.
For additional information, refer to “Ap-
proach warning” 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 oper-
ated by the driver.
The DCA system does not control vehicle
speed or warn you when you approach sta-
tionary and slow moving vehicles. You must
pay attention to vehicle operation to main-
tain proper distance from vehicles ahead.

DCA DRIVING SITUATIONS
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
detection 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 center line 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 the
vehicle traveling ahead.

When driving on some roads, such as wind-
ing, 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 af-
fected by vehicle operation (steering maneu-
ver 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.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and DCA
system display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing
∙ When the vehicle ahead is traveling faster and the distance between vehicles
is increasing
∙ When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked
or moving slowly.

NOTE:
The approach warning chime may sound and
the system display may blink when ICC sen-
sor detects vehicles in other lanes
Aor ob-
jects on the side of the roadA. This may
cause the DCA system to operate inappro-
priately. The ICC sensor may detect these
objects when the vehicle is driven on winding
roads, narrow roads, hilly roads or when en-
tering or exiting a curve. In these cases you
will have to manually control the proper dis-
tance 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 ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
SYSTEM TEMPORARILY
UNAVAILABLE
Under the following conditions, the DCA sys-
tem will not operate and the DCA cancella-
tion message will pop up:
∙ When the Drive Mode Selector switch is placed in the SNOW mode (To use the
DCA system, turn off the Drive Mode
Selector switch, then turn on the dynamic
driver assistance switch.)
For additional information about the
SNOW mode on the Drive Mode Selec-
tor switch, refer to “Snow mode” in this
section. ∙ When the VDC system is off (To use the
DCA system, turn on the VDC, then push
the dynamic driver assistance switch.)
For additional information about the
VDC system, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
∙ When ABS or VDC (including the TCS) is operating
When the Conventional (fixed speed) cruise
control mode is operating, the DCA system
will not operate. (To use the DCA system,
turn the Conventional [fixed speed] cruise
control mode off, then push the dynamic
driver assistance switch.)
For additional information about the Con-
ventional (fixed speed) cruise control mode,
refer to “Intelligent Cruise Control (ICC)” in

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the FEB with Pedes-
trian Detection system could result in seri-
ous injury or death.
∙ The FEB with Pedestrian Detection sys-tem is a supplemental aid to the driver. It
is not a replacement for the driver’s at-
tention to traffic conditions or responsi-
bility to drive safely. It cannot prevent
accidents due to carelessness or danger-
ous driving techniques.
∙ The FEB with Pedestrian Detection sys- tem does not function in all driving, traf-
fic, weather and road conditions.
The FEB with Pedestrian Detection system
can assist the driver when there is a risk of a
forward collision with the vehicle ahead in the
traveling lane or with a pedestrian. The FEB with Pedestrian Detection system
uses a radar sensor
Alocated behind the
lower grille of the front bumper to measure
the distance to the vehicle ahead in the same
lane. For pedestrians, the FEB with Pedes-
trian Detection system uses a camera
Bin-
stalled behind the windshield in addition to
the radar sensor.

SYSTEM OPERATION
The FEB with Pedestrian Detection system
operates at speeds above approximately
3 mph (5 km/h). For the pedestrian detection
function, the FEB with Pedestrian Detection
system operates at speeds between 6 –
37 mph (10 – 60 km/h).
If a risk of a forward collision with a vehicle is
detected, the FEB with Pedestrian Detection
system will first provide a warning to the
driver by flashing the vehicle ahead detection
indicator and providing an audible alert. In
addition, the FEB with Pedestrian Detection
system pushes the accelerator pedal up, and
then the system applies partial braking. If the
driver applies the brakes quickly and force-
fully, but the FEB with Pedestrian Detection
system detects that there is still the possibility
of a forward collision, the system will auto-
matically increase the braking force.
