To reset at a slower cruising speed,use
one of the following three methods:
• Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the COAST/SET switch and release it.
• Push and hold the COAST/SET switch. Release the switch when the vehicle
slows to the desired speed.
• Push and release the COAST/SET switch. Each time you do this, the set speed de-
creases by about 1 mph (1.6 km/h).
To resume the preset speed, push and
release the ACCEL/RES switch. The vehicle
returns to the last set cruising speed when
the vehicle speed is over 25 mph (40 km/h).

If the radar sensorO1detects a slower
moving vehicle ahead, the system will re-
duce 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 ap-
proximately 40% of vehicle braking power)
if necessary.
The detection range of the sensor is ap-
proximately 650 f t (200 m) ahead.

Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is re-
quired 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 us-
ing the ICC system.

2System set display without vehicle
ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, simi-
lar to standard cruise control, as long as no
vehicle is detected in the lane ahead. The
ICC system displays the set speed. Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
NOTE:
• The stop lights of the vehicle come on
when braking is performed by the ICC
system.
• When the brake operates, a noise may be heard. This is not a malfunction.
When a vehicle ahead is detected, the ve-
hicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance. Vehicle ahead not detected
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.
When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 mph (24 km/h), the sys-
tem will be canceled.

When passing another vehicle,the set
speed indicator
OAwill flash when the ve-
hicle speed exceeds the set speed. The ve-
hicle detect indicator will turn off when the
area ahead of the vehicle is open. When the
pedal is released, the vehicle will return to
the previously set speed.
Even though your vehicle speed is set in the
ICC system, you can depress the accelera-
tor pedal when it is necessary to accelerate
your vehicle rapidly.
How to change the set vehicle
speed
To cancel the preset speed, use one of the
following methods:
• Push the CANCEL switch. The set vehicle speed indicator will go out.
• Tap the brake pedal. The set vehicle speed indicator will go out.
• Push the ICC switch to off. The ICC indica- tors will go out.
To reset at a faster cruising speed, use
one of the following methods:
• Depress the accelerator pedal. When the vehicle attains the desired speed, push
and release the COAST/SET switch.
• Push and hold the ACCEL/RES switch. The set vehicle speed will increase by ap-
proximately 5 mph (5 km/h).
• Push, then quickly release the ACCEL/RES switch. Each time you do this, the set
speed will increase by approximately 1
mph (1 km/h). To reset at a slower cruising speed,
use
one of the following methods:
• Lightly tap the brake pedal. When the ve- hicle attains the desired speed, push the
COAST/SET switch and release it.
• Push and hold the COAST/SET switch. The set vehicle speed will decrease by
approximately 5 mph (5 km/h).
• Push, then quickly release the COAST/SET switch. Each time you do this, the set
speed will decrease by approximately 1
mph (1 km/h).
To resume the preset speed, push and
release the ACCEL/RES switch. The vehicle
will resume the last set cruising speed
when the vehicle speed is over 20 mph (32
km/h).

How to change the set distance
to the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traf-
fic conditions.
Each time the distance
switchOAis
pushed, the set distance will change to
long, middle, short and back to long again,
in that sequence. Distance Approximate distance at
60 mph (100 km/h)
[f t (m)]
1. Long 200 (60)
2. Middle 150 (45)
3. Short 90 (30)
• The distance to the vehicle ahead will change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
• The distance setting will remain at the current setting even if the engine is
restarted.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the sys-
tem warns the driver with the chime and
ICC system display. Decelerate by depress-
ing the brake pedal to maintain a safe ve-
hicle distance if:
• The chime sounds.
• The vehicle ahead detection indicatorblinks.
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:
• The vehicle approaches other vehicles that are parked or moving slowly.
• The accelerator pedal is depressed, over- riding the system.

5-62Starting and driving

NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects objects on the side
of the vehicle or on the side of the road.
This may cause the ICC system to deceler-
ate or accelerate the vehicle. The ICC sen-
sor may detect these objects when the
vehicle is driven on winding roads, narrow
roads, hilly roads, or when entering or ex-
iting 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 ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed:
• When the vehicle ahead is not detectedand your vehicle is traveling below the
speed of 15 mph (25 km/h)
• When the system judges the vehicle is at a standstill • When the shif t lever is not in the D (Drive)
position, Manual mode or L (Low) range.
• When the parking brake system is applied
• When the VDC system is turned off
• When VDC operates
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction 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 limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
• The ICC system is primarily intended
for use on straight, dry, open roads
with light traffic. It is not advisable to
use the ICC system in city traffic or
congested areas. •
The ICC 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 system. This system
does not correct careless, inattentive
or absentminded 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 dis-
tance to the vehicle ahead and the
surrounding circumstances 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 cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
Starting and driving5-63

•Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The ICC system may not
be able to maintain the selected dis-
tance between vehicles (following
distance) or selected vehicle speed
under some circumstances.
• The system may not detect the ve-
hicle in front of you in certain road
or weather conditions. To avoid acci-
dents, never use the ICC system un-
der the following conditions:
– 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.)
– Wheels or tires other than NISSAN
recommended are used.
– When rain, snow or dirt adhere to
the bumper around the distance
sensor
–
On steep downhill roads (the ve-
hicle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
– On repeated uphill and downhill
roads
–
When traffic conditions make it dif-
ficult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar
sources
• 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 unexpectedly
come into the sensor detection zone
and cause automatic braking. Al-
ways stay alert and avoid using the
ICC system where not recommended
in this warning section.
The radar sensor will not detect the follow-
ing 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. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system
may not maintain the selected distance.
The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly:
• When snow or road spray from traveling
vehicles reduces the sensor’s detection.
• When your vehicle is towing a trailer, etc.
• When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle.
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system.
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 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 vehicle ahead.
Be sure to check and clean the sensor
regularly.
