WARNING
Failure to follow the warnings and
instructions for proper use of the DCA
system could result in serious personal
injury or death.
.Always drive carefully and atten-
tively when using the DCA 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 situa-
tions. Do not use the DCA system
except in appropriate road and traffic
conditions.
.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.
.As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive or absent-minded driving, or
overcome poor visibility in rain, fog,
or other bad weather. Decelerate thevehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
.Always pay attention to the opera-
tion of the vehicle and be ready to
manually decelerate to maintain the
proper following distance. The DCA
system may not be able to decelerate
the vehicle under some circum-
stances.
.This system only brakes and moves
the accelerator pedal upward to help
assist the driver to maintain a follow-
ing 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 DCA system automatically de-
celerates your 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 vehicleahead or when a vehicle suddenly
appears in front of you. Always stay
alert when using the DCA system.
.If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel with a warning
chime once it judges that the vehicle
has come to a standstill. To prevent
the vehicle from moving, the driver
must depress the brake pedal.

DCA SYSTEM OPERATION
WARNING
Failure to follow the warnings and
instructions for proper use of the DCA
system could result in serious personal
injury or death.
.When the vehicle ahead detection
indicator is not illuminated, system
will not control the vehicle or warn
the driver.
.Never place your foot under the
brake pedal. Your 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 appro-
priately.
The 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 in
maintaining a following distance. The sys-
tem 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 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
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.5-96).

The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelera-
tor pedal upward in the normal driving
condition.
When a vehicle ahead is detected:
The vehicle ahead detection indicator ap-
pears.When the vehicle approaches a vehicle
ahead:
.If the driver’s foot is not on the accel-
erator pedal, the system activates the
brakes to decelerate smoothly as neces-
sary. If the vehicle ahead comes to a
stop, the vehicle decelerates to a stand-
still within the limitations 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 the driver is
required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead detec-tion indicator. 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.
NOTE:
.The stop lights of the vehicle come on
when braking is performed by the DCA
system.
.When the brake operates, a noise may be
heard. This is not a malfunction.
Overriding the system:
The following driver’s operation overrides
the system operation.
.When the driver depresses the accelera-
tor pedal even further while the system is
moving the accelerator pedal upward,
the DCA system control of the accel-
erator pedal is canceled.
.When the driver’s foot is on the accel-
erator pedal, the brake control by the
system is not operated.
.When the driver’s foot is on the brake
pedal, neither the brake control nor the
alert by the system operates.
.When the Intelligent Cruise Control (ICC)
system is set, the DCA system will be
inactive.

FCC Notice:
For USA:
This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions:
1.This device may not cause harmful
interference, and
trian detection system will provide a warning
to the driver by flashing the FEB system
emergency warning indicator (red)
, pro-
vides an audible alert and the system will
apply partial braking. If the driver applies the
brakes quickly and forcefully but the FEB
with pedestrian detection system detects
that there is still the possibility of a forward
impact with a pedestrian, the system will
automatically increase the braking force. If
the risk of collision becomes imminent and
the driver does not take action, the FEB with
pedestrian detection system automatically
applies harder braking.
NOTE:
The vehicle’s stop lights come on when any
braking is performed by the FEB with
pedestrian detection system.
Depending on vehicle speed and distance to
the vehicle or pedestrian ahead, as well as
driving and roadway conditions, the system
may help the driver avoid a forward collision
or may help mitigate the consequences of a
collision should one be unavoidable. If the
driver is handling the steering wheel, accel-
erating or braking, the FEB with pedestrian
detection system will function later or will
not function.
The automatic braking will cease under the
following conditions:.When the steering wheel is turned to
avoid a collision.
.When the accelerator pedal is depressed.
.When there is no longer a vehicle or a
pedestrian detected ahead.
If the FEB with pedestrian detection system
has stopped the vehicle, the vehicle will
remain at a standstill for approximately 2
seconds before the brakes are released.
