Operation Condition
ADAS control unit performs the control when the following conditions are satisfied.
 When the DCA system setting on the navigation screen is ON.
 When the dynamic driver assistance switch is turned to ON.
 When the brake pedal is not depressed.
 When the vehicle speed is above approximately 5 km/h (3 MPH).
 When the vehicle ahead is detected.
 When the ICC system is not set.
No Operation Condition
The ADAS control unit is not operat e when the system is under any condi tions of the no operation condition.
 When the brake pedal depressed.
 When the ICC system is set.
 When the system judges that the vehicle co mes to a standstill by the system control.
 When the vehicle ahead is not detected.
Operation Cancellation Condition
The ADAS control unit cancels the operation when the syst em is under any conditions of the operation cancel-
lation condition.
 When the dynamic driver assistance switch is turned to OFF.
 When the system malfunction occurs.
 When ABS or VDC (including the TCS) operates.
 When the VDC is turned OFF.
 When the SNOW mode switch is turned ON.
 When the 4WD shift switch is turned to not AUTO position.
 When driving into a strong light (i.e., sunlight).
 When the ICC sensor body window is dirty and the measurement of the distance between the vehicles
becomes difficult.
Operation At The Driver Operation
Give priority to the driver operation in the following situation.
When vehicle approaches a vehicle ahead If the driver is not depressing the acceler-
ator pedal, the system activates the
brakes to decelerate smoothly as neces-
sary
If the driver is depressing 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 de-
tection indicator. If the driver is depressing
the accelerator pedal after the warning,
the system moves the accelerator pedal
upward to assist the driver to switch to the
brake pedal
Deceleration control It transmits the brake fluid
pressure control signal to the ABS actuator and electric unit (control unit) via
CAN communication and performs the brake control
Accelerator pedal actuation
control It transmits the accelerator pedal feedback force control signal to the accelerator pedal actuator via ITS
communication and controls the accelerator pedal in the upward directionJSOIA0222ZZ

switch is turned ON with settings of
DCA system and LDP system OFF
The DCA system is not activated. The DCA
system switch indicator blinks.
 When the VDC or ABS (including the TCS) operates
 When the VDC is turned OFF

 When driving into a strong light (i.e., sunlight) The DCA system is automatically can-
celed. The chime will sound and the DCA
system switch indicator will blink.
NOTE:
The system operates if the dynamic driver
assistance switch is turned OFF
⇒ON after
the condition improves.
When the sensor window is dirty, mak-
ing it impossible to detect a vehicle
ahead The DCA system is automatically can-
celed. The chime sounds and the ICC sys-
tem warning lamp will come on and the
“CLEAN SENSOR” indicator will appear.
NOTE:
Stop the vehicle in a safe location and turn
the ignition switch OFF. Clean the dirty
area with soft cloth. The system returns to
normal condition when turning the ignition
switch ON again.
When the DCA system is not operating
properly The chime sounds and the ICC system
warning lamp will come on.
NOTE:
Turn the ignition switch OFF, and then turn
the ignition switch ON again. If there is no
malfunction, the system returns to the nor-
mal condition.
