VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control
mode, the ICC system automatically
maintains a selected distance from the
vehicle traveling in front of you according
to that vehicle’s speed (up to the set
speed), or at the set speed when the road
ahead is clear.
JVS0913X
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the radar sensor
detects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected 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
approximately 650 ft (200 m) ahead.

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

.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.

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

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

faces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire
chains. Always maintain a safe
distance from the vehicle in front
of you. Ultimately, the driver is
responsible for safety.
. Tire type and condition may also
affect braking effectiveness.
— When replacing tires, install
the specified size of tires on
all four wheels.
— When installing a spare tire, make sure that it is the proper
size and type as specified on
the Tire and Loading Informa-
tion label. See “Tire and load-
ing information label” (P.10-
12).
— For detailed information, see “Wheels and tires” (P.8-30).
The Anti-lock Braking System (ABS) con-
trols the brakes so the wheels do not lock
during hard braking or when braking on
slippery surfaces. The system detects the
rotation speed at each wheel and varies
the brake fluid pressure to prevent each
wheel from locking and sliding. By pre-
venting each wheel from locking, the system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes.
The ABS will operate to prevent the
wheels from locking up. Steer the vehicle
to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing
so may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric pumps, hydraulic solenoids and a
computer. The computer has a built-in
diagnostic feature that tests the system
each time you start the engine and move
the vehicle at a low speed in forward or
reverse. When the self-test occurs, you
may hear a “clunk” noise and/or feel a
pulsation in the brake pedal. This is
normal and does not indicate a malfunc-
tion. If the computer senses a malfunc-
tion, it switches the ABS off and
illuminates the ABS warning light on the
instrument panel. The brake system then
operates normally, but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked. It is recommended you
visit a NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies
according to road conditions.
When the ABS senses that one or more
wheels are close to locking up, the
actuator rapidly applies and releases
hydraulic pressure. This action is similar
to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal
and hear a noise from under the hood or
feel a vibration from the actuator when it
is operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.

The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip
based on vehicle speed (traction con-
trol function).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle
in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel
flashes so note the following: .
The road may be slippery or the
system may determine some action
is required to help keep the vehicle on
the steered path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is
off. When the VDC switch is used to turn
off the system, the VDC system still
operates to prevent one drive wheel from
slipping by transferring power to a non
slipping drive wheel. The VDC warning
light
flashes if this occurs. All other
VDC functions are off, and the VDC
warning light
will not flash. The VDC
system is automatically reset to on when
the ignition switch is placed in the OFF
position then back to the ON position.
When the 4L position is selected with the
4WD shift switch, the VDC system is
disabled and the VDC off indicator light illuminates (for 4WD models).
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-17) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-20).
The computer has a built-in diagnostic
feature that tests the system each time
you start the engine and move the vehicle
forward or in reverse at a slow speed.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
.
The VDC system is designed to
help improve driving stability but
does not prevent accidents due
to abrupt steering operation at
high speeds or by careless or
dangerous driving techniques.
Reduce vehicle speed and be
especially careful when driving
and cornering on slippery sur-
faces and always drive carefully.
. Do not modify the vehicle’s sus-
pension. If suspension parts such
as shock absorbers, struts,
springs, stabilizer bars, bushings
and wheels are not NISSAN re-
commended for your vehicle or
