SYSTEM
FUNCTION DESCRIPTION
When a vehicle is detected ahead The vehicle ahead detection indicator comes ON.
When vehicle approaches a vehicle ahead If the driver is not depressing the accelerator pedal, t
he 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 is depressing 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 indicator. If the
driver is depressing the accelerator pedal after the wa rning, the system moves the accelerator pedal upward
to assist the driver to switch to the brake pedal.
CAUTION:
If the vehicle ahead comes to a stan dstill, the vehicle decelerates to a standstill within the limitations
of the system. The system will release brake control wi th a warning chime once it judges the vehicle is
at a standstill. To prevent the vehicle from moving , the driver must depress the brake pedal. [The sys-
tem will resume control automatically once the system reaches 5 km/h (3 MPH)].
NOTE:
Depending on the position of the accelerator pedal, the system may not be able to assist the driver to
release the accelerator pedal appropriately.
When the driver depresses the accelerator pedal even further while the system is moving the acce\
lerator pedal upward, the accelerator pedal control will be canceled.
When the driver is depressing the accelerator pedal, the brake control by the system is not operated.
When the driver is depressing the brake pedal, neither the brake control nor the alert by the system oper-
ates.
When the ICC system is set, the DCA system will be canceled.
OPERATION DESCRIPTION
ICC sensor calculates a distance from a vehicle ahead and a relative speed to transmit the ICC sensor signal
to the ADAS control unit via ITS communication. Based on the received signal, the ADAS control unit trans-
mits a control signal to the accelerator pedal actuator via ITS communication and to the ABS actuator control
unit (control unit) via CAN communication.

Precautions for Distance Control AssistINFOID:0000000006223505
If the vehicle ahead comes to a stop, the vehicle deceler
ates to a standstill within the limitations of the sys-
tem. The system will cancel once it judges that the vehi cle has come to a standstill with a warning chime. To
prevent the vehicle from moving, t he driver must depress the brake pedal.
The DCA system will not apply brake control while the driver is depressing the accelerator pedal.
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 safe ly and be in control of the vehicle at all times.
This system will not adapt automatically to road condi tions. 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 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
As there is a performance limit to the distance contro l function, never rely solely on the DCA system. This
system does not correct careless, inat tentive or absent-minded driving, or overcome poor visibility in rain,
fog, or other bad weather. Decelerate the vehi cle 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 own v ehicle 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.
- On off-road surfaces such as on sand or rock, etc.
- During bad weather (rain, fog, snow, etc.)
- When strong light (for example, at sunrise or sunset) is directly shining on the front of the vehicle
- When rain, snow or dirt adhere to the system sensor
- On steep downhill roads (frequent braking may result in overheating the brakes)
- On repeated uphill and downhill roads
- When towing a trailer or other vehicle
In some road or traffic conditions, a vehicle or objec t can unexpectedly come into the sensor detection zone
and cause automatic braking. Driver may need to control the distance from other vehicles using the acceler-
ator pedal. Always stay alert and avoid using the DCA system when it is not recommended in this section.
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) fr om vehicles reduces the sensor's visibility
- When excessively heavy baggage is loaded in the rear seat or the luggage room of own vehicle
The DCA system is designed to autom atically 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 trans-
parent or translucent vinyl bag, etc., the DCA syste m may not detect them. In these instances, the DCA sys-
tem may not be able to decelerate 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 decel-
erates to 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 dis-
tance between vehicles may become closer because t he DCA system cannot decelerate the vehicle quickly
enough. If this occurs, the DCA system will sound a warn ing chime and blink the system display to notify the
driver to take necessary action.
The DCA system does not control vehicle speed or warn when driver approach stationary and slow moving
vehicles. Driver must pay attention to vehicle operat ion 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 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 driver 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, nar- row 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 inap-
propriately. The detection of vehicles may also be affected by vehi-
cle operation (steering maneuver or traveling position in the lane,
etc.) or vehicle condition. If this occurs, the system may warn
driver by blinking the system indicator and sounding the chime
unexpectedly. The driver will have to manually control the proper
distance away from the vehicle traveling ahead.
The approach warning chime may sound and the system display may blink when the sensor detects some reflectors which are fitted
on vehicles in other lanes or on the side of the road. This may
cause the DCA system to operate inappropriately. The sensor may
detect these reflectors when the vehicle is driven on winding
roads, hilly roads or when entering or exiting a curve. The sensor
may also detect reflectors on narrow roads or in road construction
zones. In these cases driver will have to manually control the
proper distance ahead of own 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).
The DCA system automatically dec elerates own vehicle to help
assist the driver to maintain a following distance from the vehicle
ahead. Manually brake when deceleration is required to maintain a safe distance upon sudden braking by
the vehicle ahead or when a vehicle suddenly appears in front of own vehicle. Always stay alert when using
the DCA system.
When the vehicle ahead detection indicator lamp is not illum inated, system will not control or warn the driver.
Never place a foot under the brake pedal. A foot may be caught when the system controls the brake.
Depending on the position of the accelerator pedal, the system may not be able to assist the driver to
release the accelerator pedal appropriately.
If the vehicle ahead comes to a standstill, the vehicle decel erates to a standstill within the limitations of the
system. The system will rel ease brake control with a warning chime once it judges the vehicle is at a stand-
still. To prevent the vehicle from moving, the driv er must depress the brake pedal. [The system will resume
control automatically once the system reaches 5 km/h (3 MPH)].
