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 automatically
check the sensor’s operation within the limitation
of the system. When the sensor is covered with
dirt or is obstructed, the system will automati-
cally 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 con-
trol mode may not cancel and may not be able to
maintain the selected following distance from
the vehicle 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 centerline 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
traveling 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 accel-
erate 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 traveling ahead.

Condition B:
When the radar sensor area of the front bumper
is covered with dirt or is obstructed, making it
impossible to detect a vehicle ahead, the ICC
system is automatically canceled.
The chime sounds and the ICC system warning
light (orange) will come on and the “FRONT
RADAR OBSTRUCTION” warning will appear.
Action to take:
If the warning light comes on, park 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 interrupted, clean the sensor area of the front bumper and restart the
engine. If the “FRONT RADAR OBSTRUC-
TION” warning continues to be displayed, have
the ICC system checked. It is recommended you
visit a NISSAN dealer for this service.

Condition C:
When the ICC system is not operating properly,
the chime sounds and the ICC system warning
light (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, resume driving and set the ICC system
again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the
ICC system is malfunctioning. Although
the vehicle is still driveable under normal
conditions, have the vehicle checked. It isrecommended you visit a NISSAN dealer
for this service.

System maintenance
The sensor for the ICC system*Ais located
below the front bumper.
To keep the ICC system operating properly, 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.) . This could

.The DCA system automatically de-
celerates your vehicle to help assist
the driver to maintain a following
distance from the vehicle ahead.
Manually brake when deceleration
is required to maintain a safe dis-
tance upon sudden braking by the
vehicle ahead or when a vehicle
suddenly appears in front of you.
Always stay alert when using the
DCA system.
. If the vehicle ahead comes to a stop,
the vehicle decelerates to a stand-
still within the limitations of the
system. The system will cancel 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
*Adetects a slower moving
vehicle ahead, the system will reduce the vehicle
speed to help assist the driver to maintain a
following distance.
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 approxi-
mately 650 ft (200 m) ahead.

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 accelerator
pedal even further while the system is
moving the accelerator pedal upward, the
DCA system control of the accelerator pedal
is canceled.
. When the driver’s foot is on the accelerator
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
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 DCA 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 distance between
vehicles. Some examples are:
. When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
. When the vehicle ahead is traveling faster
and the distance between vehicles 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 DCA system to decelerate or accelerate the vehicle. The radar sensor
may detect 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 affected 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) .

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 DCA sys-
tem 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 downhill roads
— When towing a trailer or other vehicle
. In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection
zone and cause automatic braking. You may need to control the dis-
tance from other vehicles using the
accelerator pedal. Always stay alert
and avoid using the DCA 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
