System operation
The driver sets the desired vehicle speed
based on the road conditions. The ICC
system maintains the set vehicle speed,
similar to standard cruise control, as long
as no vehicle is detected in the lane ahead.
The ICC system displays the set speed.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by
controlling the throttle and applying thebrakes to match the speed of a slower
vehicle ahead. The system then controls the
vehicle speed based on the speed of the
vehicle ahead to maintain the driver selected
distance.
The stoplights of the vehicle come on when
braking is performed by the ICC system.
When the brake operates, a noise may be
heard and/or vibration may be felt. This is
not a malfunction.
When a vehicle ahead is detected, the
vehicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance.Vehicle ahead not detected:
When a vehicle is no longer detected ahead,
the ICC system gradually accelerates your
vehicle to resume the previously set vehicle
speed. The ICC system then maintains the
set speed.
When a vehicle is no longer detected the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system
controls the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the
system will be canceled.

keeping your foot on the accelerator pedal.
WARNING
.In the conventional (fixed speed)
cruise control mode, a warning chime does not sound to warn you if you are
too close to the vehicle ahead, as
neither the presence of the vehicle
ahead nor the vehicle-to-vehicle dis-
tance is detected.
. Pay special attention to the distance
between your vehicle and the vehicle
ahead of you or a collision could
occur.
. Always confirm the setting in the ICC
system display.
. Do not use the conventional (fixed
speed) cruise control mode when
driving under the following condi-
tions.
— when it is not possible to keep the vehicle at a set speed
— in heavy traffic or in traffic that varies in speed
— on winding or hilly roads
— on slippery roads (rain, snow, ice, etc.)
— in very windy areas
Doing so could cause a loss of vehicle
control and result in an accident.

(brake operation is necessary)
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 (green)
comes on. 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 (orange). 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 and/or vibration may be felt. 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
cancelled.
