DCA SYSTEM OPERATION
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious personal injury or
death.
∙ When the vehicle ahead detection indica-tor light is not illuminated, the 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 accel- erator pedal, the system may not be able
to assist the driver to release the accel-
erator pedal appropriately.
LSD3207
5-140Starting and driving

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 in
maintaining a following distance. The system
will decelerate as necessary and if the vehicle
ahead comes to a stop, the vehicle deceler-
ates to a standstill. However, the DCA sys-
tem can only apply up to approximately 40%
of the vehicle’s total braking power. If a ve-
hicle 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 de-
celerate 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 addi-
tional information, refer to “Approach warn-
ing” in this section.The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelerator
pedal upward in the normal driving condition.
When a vehicle is detected ahead:
The vehicle ahead detection indicator comes
on.When vehicle approaches a vehicle ahead:
∙ If the driver’s foot is not on the accelera- tor pedal, the 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 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 re-
lease the accelerator pedal.
When brake operation by 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 sys-
tem 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.

HOW TO ENABLE/DISABLE THE
DCA SYSTEM
To turn on the DCA system, push the dynamic
driver assistance switch (for models without
ProPILOT Assist) or the ProPILOT Assist
switch (for models with ProPILOT Assist) on
the steering wheel after starting the engine.
The DCA system switch indicator light in the
vehicle information display will illuminate.
Push the dynamic driver assistance switch
(for models without ProPILOT Assist) or the
ProPILOT Assist switch (for models with
ProPILOT Assist) on the steering wheel again
to turn off the DCA system. The DCA system
switch indicator light will turn off.
The system will start to operate after the
vehicle speed becomes above approximately
3 mph (5 km/h).
The dynamic driver assistance switch (for
models without ProPILOT Assist) or the Pro-
PILOT Assist switch (for models with ProPI-
LOT Assist) on the steering wheel is used for
the LDP, DCA and BSI systems. When the
dynamic driver assistance switch (for models
without ProPILOT Assist) or the ProPILOT
Assist switch (for models with ProPILOT As-
sist) on the steering wheel is pushed, the LDP
system will also turn on or off simultaneously.
The DCA system can be individually set to on

ger present, turn the system off with the
dynamic driver assistance switch (for models
without ProPILOT Assist) or the ProPILOT
Assist switch (for models with ProPILOT As-
sist) on the steering wheel. Turn the DCA
system back on to use the system. Condition B:
When the radar sensor area is covered with
dirt or is obstructed, making it impossible to
detect a vehicle ahead, the DCA system is
automatically canceled.

“Unavailable: Front Radar Blocked” warning
will appear.
Action to take:
If the warning light comes on, park the vehicle
in a safe place, press the park button to place
the vehicle in the P (Park) position and turnthe engine off. When the radar signal is tem-
porarily interrupted, clean the sensor area
and restart the engine. If the “Unavailable:
Front Radar Blocked” warning continues to
be displayed, have the DCA system checked.

1. Vehicle ahead detection indicator
2. FEB with Pedestrian Detection emer-gency warning indicator
3. FEB with Pedestrian Detection system warning light
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. If the risk of a collision becomes imminent
and the driver does not take action, the FEB
with Pedestrian Detection system issues the
second warning to the driver by flashing the
FEB with Pedestrian Detection emergency
warning indicator (red), providing an audible
warning, and then automatically applies
harder braking.
If a risk of a forward impact with a pedestrian
is detected, the FEB with Pedestrian Detec-
tion system will provide a warning to the
driver by flashing the FEB with Pedestrian
Detection emergency warning indicator (red),
provides an audible alert and the system will
apply partial baking. 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 au-
tomatically 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 brake lights come on when any
braking is performed by the FEB with Pedes-
trian 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 if a
collision should be unavoidable. If the driver is
handling the steering wheel, accelerating 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 re-
main at a standstill for approximately 2 sec-
onds before the brakes are released.

FEB WITH PEDESTRIAN
DETECTION SYSTEM
LIMITATIONS
WARNING
Listed below are the system limitations for
the FEB with Pedestrian Detection system.
Failure to operate the vehicle in accordance
with these system limitations could result
in serious injury or death.
∙ The FEB with Pedestrian Detection sys-tem cannot detect all vehicles or pedes-
trians under all conditions.
∙ The radar sensor FEB with Pedestrian Detection system does not detect the
following objects:
– Small pedestrians (including small children), animals and cyclists.
– Pedestrians in wheelchairs or using mobile transport such as scooters,
child-operated toys, or skateboards.
– Pedestrians who are seated or other- wise not in a full upright standing or
walking position.
– Oncoming vehicles
– Crossing vehicles – Obstacles on the roadside
∙ The FEB with Pedestrian Detection sys- tem has some performance limitations.
– If a stationary vehicle is in the vehicle’s path, the FEB with Pedestrian Detec-
tion system will not function when the
vehicle is driven at speeds over ap-
proximately 50 mph (80 km/h).
– For pedestrian detection, the FEB with Pedestrian Detection system will
not function when the vehicle is driven
at speeds over approximately 37 mph
(60 km/h) or below approximately
6 mph (10km/h).
∙ The FEB with Pedestrian Detection sys- tem will not function for pedestrians in
darkness or in tunnels, even if there is
street lighting in the area.
∙ For pedestrians, the FEB with Pedestrian Detection system will not issue the first
warning and will not push the accelerator
pedal up.
∙ The FEB with Pedestrian Detection sys- tem may not function if the vehicle ahead
is narrow (for example, a motorcycle). ∙ The FEB with Pedestrian Detection sys-
tem may not function if speed difference
between the two vehicles is too small.
∙ The radar sensor FEB with Pedestrian Detection system may not function prop-
erly or detect a vehicle ahead in the fol-
lowing conditions:
– Poor visibility (conditions such as rain, snow, fog, dust storms, sandstorms,
and road spray from other vehicles).
– Driving on a steep downhill slope or roads with sharp curves.
– Driving on a bumpy road surface, such as an uneven dirt road.
– If dirt, ice, snow or other material is covering the radar sensor area.
– Interference by other radar sources.
– The camera area of the windshield is fogged up, or covered with dirt, water
drops, ice, snow, etc.
– Strong light (for example, sunlight or high beams from oncoming vehicles)
enters the front camera. Strong light
causes the area around the pedestrian
to be cast in a shadow, making it diffi-
cult to see.
