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.

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
