safe vehicle distance if:
.The chime sounds.
. The vehicle ahead detection and set
distance indicator blink.
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 other vehi-
cles that are parked or moving slowly.
. The accelerator pedal is depressed,
overriding the system.
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
ICC 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).
Automatic cancellation
A chime sounds under the following
conditions and the control is automati-
cally canceled.
.
When the vehicle ahead is not de-
tected and your vehicle is traveling
below the speed of 15 MPH (24 km/h)
. When the system judges the vehicle is
at standstill
. When the shift lever is not in the D
(Drive) or manual shift mode
. When the parking brake is applied
. When the SNOW mode switch is
pushed on.
. When the 4WD shift switch is in the 4H
or 4L position (for 4WD models)
. When the VDC system is turned off
. When ABS or VDC (including the trac-
tion control system) operates .
When distance measurement be-
comes impaired due to adhesion of
dirt or obstruction to the sensor
. When a wheel slips
. When the radar signal is temporarily
interrupted
Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limita-
tions for the ICC system. Failure to
operate the vehicle in accordance
with these system limitations could
result in serious injury or death.
.The system is primarily intended
for use on straight, dry, open
roads with light traffic. It is not
advisable to use the system in
city traffic or congested areas.
. This system will not adapt auto-
matically to road conditions. This
system should be used in evenly
flowing traffic. Do not use the
system on roads with sharp
curves, or on icy roads, in heavy
rain or in fog.

.As there is a performance limit to
the distance control function,
never rely solely on the ICC sys-
tem. This system does not correct
careless, inattentive or absent-
minded driving, or overcome
poor visibility in rain, fog, or other
bad weather. Decelerate the ve-
hicle 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.
. 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 once it judges that the vehicle
has come to a standstill and
sound a warning chime. To pre-
vent the vehicle from moving, the
driver must depress the brake
pedal.
. Always pay attention to the op-
eration of the vehicle and be
ready to manually control the
proper following distance. The
vehicle-to-vehicle distance con-
trol mode of the ICC system may
not be able to maintain the se-
lected distance between vehicles (following distance) or selected
vehicle speed under some cir-
cumstances.
. The system may not detect the
vehicle in front of you in certain
road or weather conditions. To
avoid accidents, never use the ICC
system under the following con-
ditions:
— On roads where the traffic is
heavy or there are sharp
curves
— On slippery road surfaces such as on ice or snow, etc.
— During bad weather (rain, fog, snow, etc.)
— When rain, snow or dirt adhere to the system sensor
— On steep downhill roads (the vehicle may go beyond the set
vehicle speed and frequent
braking may result in over-
heating the brakes)
— On repeated uphill and down- hill roads
— When traffic conditions make it difficult to keep a proper
distance between vehicles be-
cause of frequent accelera- tion or deceleration
. Do not use the ICC system if you
are towing a trailer. The system
may not detect a vehicle ahead.
. 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 ICC 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 sensor generally detects the signals
returned from the vehicle ahead. There-
fore, if the sensor cannot detect the
reflection from the vehicle ahead, the
ICC system may not maintain the se-
lected distance.
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
area of your vehicle
. When your vehicle is towing a trailer,
etc.
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitation of the system. When the
sensor is covered with dirt or is ob-
structed, the system will automatically
be canceled. If the sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them.
In these instances, the vehicle-to-vehicle
distance control mode may not cancel
and may not be able to maintain the
selected following distance from the ve-
hicle ahead. Be sure to check and clean
the sensor regularly.
SSD0252
The detection zone of the ICC sensor is
limited. A vehicle ahead must be in the
detection zone for the vehicle-to-vehicle
distance detection mode to maintain the
selected distance from the vehicle ahead.
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 ICC system
may warn you by blinking the system
indicator and sounding the chime. The
driver may have to manually control the proper distance away from vehicle tra-
veling ahead.

SSD0253
When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
ICC sensor may detect vehicles in a
different lane, or may temporarily not
detect a vehicle traveling ahead. This
may cause the ICC system to decelerate
or accelerate the vehicle.
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 ICC 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.

warning light (orange) will come on and
the “FRONT RADAR OBSTRUCTION” warn-
ing message will appear in the vehicle
information display.
. When the radar sensor area of the
front bumper is covered with dirt or is
obstructed
Action to take:
If the warning light (orange) comes on or
warning message appears, stop the ve- hicle in a safe place, place the shift lever in
the P (Park) position and turn the engine
off. When the radar signal is temporarily
interrupted, clean the sensor area of the
front bumper and restart the engine. If
the warning light (orange) stays on or
warning message continues to be dis-
played, have the ICC 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:
When the above conditions no longer
exist, the ICC system will resume auto-
matically.

System maintenance
The sensor for the ICC systemis
located below the front bumper.
To keep the ICC system operating prop-
erly, be sure to observe the following:
. Always keep the sensor area of the
front bumper clean.
. Do not strike or damage the areas
around the sensor.
. Do not cover or attach stickers or
similar objects on the front bumper
near the sensor area. This could cause
failure or malfunction.
. Do not attach metallic objects near
the sensor area (brush guard, etc.).

5-86Starting and driving
.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.
JVS0913X
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).
