When driving on the freeway at a set speed and
approaching a slower traveling vehicle ahead,
the ICC system will adjust the speed to maintain
the distance, selected by the driver, from the
vehicle ahead. If the vehicle ahead changes
lanes or exits the freeway, the ICC system will
accelerate and maintain the speed up to the set
speed. Pay attention to the driving operation to
maintain control of the vehicle as it accelerates
to the set speed.
The vehicle may not maintain the set speed on
winding or hilly roads. If this occurs, you will
have to manually control the vehicle speed.
Normally when controlling the distance to a
vehicle ahead, this system automatically accel-erates or decelerates your vehicle according to
the speed of the vehicle ahead. Depress the
accelerator to properly accelerate your vehicle
when acceleration is required for a lane change.
Depress the brake pedal when deceleration is
required to maintain a safe distance to the
vehicle ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when using the
ICC system.

.The chime sounds.
. The vehicle ahead detection and set dis-
tance indicator blink.
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 other vehicles that
are parked or moving slowly.
. The accelerator pedal is depressed, over-
riding 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 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) .
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.
.
When the vehicle ahead is not detected 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 traction
control system) operates .
When distance measurement becomes im-
paired due to adhesion of dirt or obstruction
to the sensor
. When a wheel slips
. When the radar signal is temporarily inter-
rupted

limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in ser-
ious 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 con-
gested areas.
. This system will not adapt automa-
tically to road conditions. This sys-
tem 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.

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.

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) .

FEB SYSTEM OPERATION
The FEB system operates at speeds above
approximately 3 MPH (5 km/h) .
If a risk of a forward collision is detected, the
FEB system will provide the first warning to the
driver by illuminating the warning in the vehicle
information display and providing an audible
warning. In addition, the FEB 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 FEB 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 FEB 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 FEB system.
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 beunavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB 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 depressed.
. When there is no longer a vehicle detected
ahead.
If the FEB system has stopped the vehicle, the
vehicle will remain at a standstill for approxi-
mately 2 seconds before the brakes are
released.

SONAR SYSTEM OFF SWITCH
The sonar system OFF switch on the lower side
of the instrument panel allows the driver to turn
the sonar system on and off. To turn the sonar
system on and off, the ignition switch must be in
the ON position. The indicator light
*1on the
switch will illuminate when the system is turned
off. If the indicator light flashes when the sonar
system is not turned off, it may indicate a
malfunction in the sonar system.
The sonar system will turn on automatically
under the following conditions.
. When the ignition switch is turned from the
OFF position to the ON position. .
When the shift lever is in the R (Reverse)
position.
. When the vehicle speed is less than 6 MPH
(10 km/h) .
The automatic turning on function can be turned
on and off by pushing the switch for more than 4
seconds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.

POWER STEERING

BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force than a
conventional brake booster even with light pedal
force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal surfaces 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 Information
label. See “Tire and loading
information label” (P.10-12) .
— For detailed information, see “Wheels and tires” (P.8-30) .
The Anti-lock Braking System (ABS) controls
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 preventing 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 dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
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 malfunction. If the computer senses
a malfunction, it switches the ABS off and
Starting and driving5-137
BRAKE ASSIST

5-138Starting and driving
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates 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. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, the VDC system helps to perform the
following functions.
.
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 control 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 conditions) .
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 automatically 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 lightwill 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) warning
light” (P.2-17) and “Vehicle Dynamic Control
(VDC) off indicator light” (P.2-20).
