.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.

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. .
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

SSD0252
The detection zone of the sensor is
limited. A vehicle ahead must be in the
detection zone for the system to operate.
A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the center-
line of the lane. A vehicle that is entering
the lane ahead may not be detected until
the vehicle has completely moved into
the lane.If this occurs, the system may
warn you by blinking the system indi-
cator and sounding the chime. The
driver may have to manually control
the proper distance away from vehicle
traveling ahead.

SSD0253
When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
sensor may detect vehicles in a different
lane, or may temporarily not detect a
vehicle traveling ahead. This may cause
the system to work inappropriately.
The detection of vehicles may also be
affected by vehicle operation (steering
maneuver or traveling position in the
lane, etc.) or vehicle condition.If this
occurs, the system may warn you by
blinking the system indicator and
sounding the chime unexpectedly. You
will have to manually control the proper
distance away from the vehicle travel-
ing ahead.

appears, stop the vehicle in a safe place,
place the shift lever in the P (Park)
position and turn the engine off. When
the radar signal is temporarily inter-
rupted, clean the sensor area of the front
bumper and restart the engine. If the
warning message continues to be dis-
played, have the I-DC system checked. It is
recommended you visit a NISSAN dealer
for this service.
.
When driving on roads with limited
road structures or buildings (for ex-
ample, long bridges, deserts, snow
fields, driving next to long walls)
Action to take:

SYSTEM MALFUNCTION
Condition:
When the I-DC system is not operating
properly, the chime sounds and the
system warning light (“CRUISE” orange)
will come on.
Action to take:
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, and turn on the I-DC
system again.
If it is not possible to set the system or
the indicator stays on, it may indicate
that the system is malfunctioning.

SYSTEM MAINTENANCE
The sensor for the I-DC systemis
located below the front bumper.
The I-DC system is designed to automa-
tically check the sensor’s operation. When
the sensor is covered with dirt or is
obstructed, the system will automatically
be canceled. If the sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the I-DC system may not detect
them. In these instances, the I-DC system
may not be able to decelerate the vehicle
properly. Be sure to check and clean the
sensor regularly.
To keep the I-DC system operating prop-
erly, be sure to observe the following:
