.The I-DC system automatically
decelerates your vehicle to help
assist the driver to maintain a
following distance from the vehi-
cle ahead. Manually brake when
deceleration is required to main-
tain a safe distance upon sudden
braking by the vehicle ahead or
when a vehicle suddenly appears
in front of you. Always stay alert
when using the I-DC system.
. If the vehicle ahead comes to a
stop, the vehicle decelerates to a
standstill within the limitations of
the system. The system will can-
cel 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.

The system is intended to assist the driver
to keep a following distance from the
vehicle ahead traveling in the same lane
and direction.
If the radar sensor
detects a slower
moving vehicle ahead, the system will
reduce the vehicle speed to help assist
the driver to maintain a following dis-
tance.
The system automatically controls the
throttle and applies the brakes (up to
approximately 40% of vehicle braking
power) if necessary.
The detection range of the sensor is
approximately 650 ft (200 m) ahead.

I-DC SYSTEM OPERATION
WARNING
Failure to follow the warnings and
instructions for proper use of the I-
DC system could result in seriouspersonal injury or death.
.
When the vehicle ahead detection
indicator light is not illuminated,
system will not control the vehi-
cle 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 appropriately.
The I-DC 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 system will decelerate as necessary
and if the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill.
However, the I-DC system can only apply
up to approximately 40% of the vehicle’s
total braking power. If a vehicle moves
into the traveling lane ahead or if a
vehicle traveling ahead rapidly decele-
rates, the distance between vehicles
may become closer because the I-DC
system cannot decelerate the vehicle

quickly enough. If this occurs, the I-DC
system will sound a warning chime and
blink the system display to notify the
driver to take necessary action.
See “Approach warning” (P.5-95).

System set display with a vehicle ahead
System set display without a vehicle
ahead
The I-DC system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accel-
erator pedal upward in the normal driving
condition.
When a vehicle ahead is detected:
The vehicle ahead detection indicator
comes on.
When the vehicle approaches a vehicle
ahead:
.If the driver’s foot is not on the
accelerator pedal, the system acti-
vates 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 accel-
erator 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
detection indicator. If the driver’s foot is
on the accelerator pedal after the warn-
ing, 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 I-DC 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 accel-
erator pedal even further while the
system is moving the accelerator
pedal upward, the I-DC system control
of the accelerator 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 I-DC system
will be inactive.Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle or if another vehicle cuts in, the
system warns the driver with the chime
and I-DC system display. Decelerate by
depressing the brake pedal to maintain a
safe vehicle distance if:
.The chime sounds.
. The vehicle ahead detection indicator
blinks.
The warning chime may not sound in
some cases when there is a short dis-
tance between vehicles. Some examples
are:
. When the vehicles are traveling at the
same speed and the distance be-
tween vehicles is not changing
. When the vehicle ahead is traveling
faster and the distance between ve-
hicles is increasing
. When a vehicle cuts in near your
vehicle
The warning chime will not sound when
your vehicle approaches vehicles that are
parked or moving slowly.
NOTE:
The approach warning chime may
sound and the system display may
blink when the radar sensor detects
objects on the side of the vehicle or on the side of the road. This may cause the
I-DC system to decelerate or accelerate
the vehicle. The radar sensor may de-
tect these objects when the vehicle is
driven on winding roads, narrow roads,
hilly roads or when entering or exiting a
curve. In these cases you will have to
manually control the proper distance
ahead of your vehicle.
Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the lane)
or traffic or vehicle condition (for example,
if a vehicle is being driven with some
damage).

I-DC SYSTEM LIMITATIONS
WARNING
Listed below are the system limita-
tions of the I-DC system. Failure to
operate the vehicle in accordance
with these system limitations could
result in serious injury or death.
.This system will not adapt auto-
matically to road conditions. Do
not use the system on roads with
sharp curves, or on icy roads, in
heavy rain or in fog.
. The I-DC system will not apply
brake control while the driver’s
foot is on the accelerator pedal.
. As there is a performance limit to
the distance control function,
never rely solely on the I-DC
system. This system does not
correct careless, inattentive or
absent-minded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate
the vehicle speed by depressing
the brake pedal, depending on
the distance to the vehicle ahead
and the surrounding circum-
stances in order to maintain a
safe distance between vehicles.
Starting and driving5-97

5-98Starting and driving
.The system may not detect the
vehicle in front of you in certain
road or weather conditions. To
avoid accidents, never use the I-
DC system under the following
conditions:
— On roads with sharp curves
— On slippery road surfaces
such as on ice or snow, etc.
— On off-road surfaces such as on sand or rock, etc.
— During bad weather (rain, fog, snow, etc.)
— When rain, snow or dirt adhere to the system sensor
— On steep downhill roads (fre- quent braking may result in
overheating the brakes)
— On repeated uphill and down- hill roads
— When towing a trailer or other vehicle
. In some road or traffic conditions,
a vehicle or object can unexpect-
edly come into the sensor detec-
tion zone and cause automatic
braking. You may need to control
the distance from other vehicles
using the accelerator pedal. Al- ways stay alert and avoid using
the I-DC system when it is not
recommended in this section.
The radar sensor will not detect the
following objects:
. Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the
travel lane
The following are some conditions in
which the sensor cannot detect the
signals:
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
room of your vehicle

information display)
AEB system warning light (on the instru-
ment panel)
Center multi-function control panel
AEB SYSTEM OPERATION
The AEB system operates at speeds
above approximately 3 MPH (5 km/h).
If a risk of a forward collision is detected,
the AEB system will provide the first
warning to the driver by blinking the
vehicle ahead detection indicator in the
vehicle information display and providing
an audible warning. In addition, the AEB
system pushes the accelerator pedal up.
If the driver releases the accelerator
pedal, then the system applies partial
braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the AEB
system detects that there is still the
possibility of a forward collision, the
system will automatically increase the
braking force.
If a forward collision is imminent and the
driver does not take action, the AEB
system issues the second visual (flashing)
and audible warning and automatically
applies harder braking.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the AEB sys-
tem.
Depending on vehicle speed and distance
to the vehicle 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, accelerating or braking, the AEB
system will function later or will not
function.
The automatic braking will cease under
the following conditions:
.When the steering wheel is turned as
far as necessary to avoid a collision.
. When the accelerator pedal is de-
pressed.
. When there is no longer a vehicle
detected ahead.
If the AEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the
brakes are released.
