WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious injury or death.
∙ DCA helps maintain a distance to the ve-hicle in front under certain conditions. It
is not a collision avoidance system. Fail-
ure to apply the brakes could result in an
accident.
∙ Always drive carefully and attentively when using the DCA system. Read and
understand the Owner’s Manual thor-
oughly before using the DCA system. Do
not use the DCA system except in appro-
priate 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 mov-
ing, 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. The DCA system brakes and moves the ac-
celerator pedal upward according to the dis-
tance from and the relative speed of the ve-
hicle ahead to help assist the driver to
maintain a following distance.
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 DCA system may not be able to deceler-
ate the vehicle under some circumstances.
The DCA system uses a sensor
Alocated
behind the front bumper of the vehicle to
detect vehicles traveling ahead. The sensor
generally detects the signals returned from
the vehicle ahead. Therefore, if the sensor
cannot detect the reflection from the vehicle
ahead, the DCA system may not operate.

DISTANCE CONTROL ASSIST (DCA)
(if so equipped)
5-98Starting and driving

The system is intended to assist the driver to
keep a following distance from the vehicle
ahead traveling in the same lane and direc-
tion.
The distance sensor is located behind the
front bumper
A. If the distance sensorA
detects a slower moving vehicle ahead, the
system will reduce the vehicle speed to help
assist the driver to maintain a following dis-
tance.
The system automatically controls the
throttle and applies the brakes (up to 40% of
vehicle braking power) if necessary.
The detection range of the sensor is approxi-
mately 490 ft (150 m) ahead.
The distance sensor will not detect the fol-
lowing objects:∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane The display is located between the speedom-
eter and tachometer.
1. DCA system switch indicator: Indicates that the dynamic driver assis-
tance switch is on. 2. Vehicle ahead detection indicator:
Indicates whether it detects a vehicle in
front of you.
WARNING
The DCA system automatically decelerates
your vehicle to help assist the driver to
maintain a following distance from the ve-
hicle ahead. Manually brake when decel-
eration is required to maintain a safe dis-
tance upon sudden braking by the vehicle
ahead or when a vehicle suddenly appears
in front of you. Always stay alert when us-
ing the DCA system.

DCA SYSTEM LIMITATIONS
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 re-
sponsibility to stay alert, drive safely and
be in control of the vehicle at all times.
∙ This system will not adapt automatically to road conditions.
∙ As there is a performance limit to the dis- tance control function, never rely solely
on the DCA system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain 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 to the sensor area of the front bumper
– On steep downhill roads (frequent braking may result in overheating the
brakes)
– On repeated uphill and downhill roads
∙ Do not use the DCA system if you are towing a trailer. The system may not de-
tect a vehicle ahead.
∙ In some road or traffic conditions, a ve- hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to con-
trol the distance from other vehicles us-
ing the accelerator pedal. Always stay
alert and avoid using the DCA system
where not recommended in this warning
section.
5-102Starting and driving

The following are some conditions in which
the sensor cannot detect the signals:∙ When the reflector of the vehicle ahead is covered with dirt, snow and road spray
∙ When dense exhaust or other smoke (black smoke) from vehicles reduces the
sensor’s detection
∙ 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 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 oc-
curs, the system may warn you by blinking the system indicator and sounding the
chime. The driver may have to manually con-
trol the proper distance away from the ve-
hicle traveling ahead.
DCA Detection Zone
SSD0252
5-104Starting and driving

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 indica-
tor 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.

Starting and driving5-105

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 road
A. 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 driv-
ing position in the lane) or traffic or vehicle
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 SNOW mode switch is on (To use the DCA system, turn off the SNOW
mode switch, then turn on the dynamic
driver assistance switch.)
For additional information about the
SNOW mode switch, refer to “Snow
