WARNING
Excessive noise (for example, audio system
volume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.
.The radar sensors may not be able to
detect and activate BSW when certain
objects are present such as:
— Pedestrians, bicycles, animals
— Several types of vehicles such as
motorcycles
— Oncoming vehicles
— Vehicles remaining in the detection
zone when you accelerate from a
stop
(See “BSW driving situations” (P.5-
30).)
— A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle
(See “BSW driving situations” (P.5-
30).)
— A vehicle approaching rapidly from
behind. (See
“BSW driving situations” (P.5-
30).)
— A vehicle which your vehicle over-
takes rapidly.
(See “BSW driving situations” (P.5-
30).)
. Severe weather or road spray condi-
tions may reduce the ability of the
radar to detect other vehicles.
. The radar sensors detection zone is
designed based on a standard lane
width. When driving in a wider lane, the
radar sensors may not detect vehicles
in an adjacent lane. When driving in a
narrow lane, the radar sensors may
detect vehicles driving two lanes away.
. The radar sensors are designed to
ignore most stationary objects, how-
ever objects such as guardrails, walls,
foliage and parked vehicles may occa-
sionally be detected. This is a normal
operating condition.

BSW DRIVING SITUATIONS
Another vehicle approaching from
behind
The BSW indicator light illuminates if a
vehicle enters the detection zone from
behind in an adjacent lane.
However, if the overtaking vehicle is
traveling much faster than your vehicle,
the indicator light may not illuminate
before the detected vehicle is beside your
vehicle. Always use the side and rear
mirrors and turn and look in the direction
your vehicle will move to ensure it is safe
to change lanes.

SSD1031
If the driver activates the turn signal, then
the BSW indicator light flashes and a
chime will sound twice.
NOTE:
If the driver activates the turn signal
before a vehicle enters the detection zone,
the BSW indicator light will flash but no
chime will sound when the other vehicle is
detected.
SSD1032
NOTE:
If you accelerate from a stop with a vehicle
in the detection zone, the other vehicle
may not be detected.
SSD1033
Overtaking other vehicles
The BSW indicator light illuminates if you
overtake a vehicle and that vehicle stays in
the detection zone for approximately 3
seconds.
The radar sensors may not detect slower
moving vehicles if they are passed quickly.

SSD1037
Entering from the side
The BSW indicator light illuminates if a
vehicle enters the detection zone from
either side.
NOTE:
The radar sensors may not detect a vehicle
which is traveling at about the same speed
as your vehicle when it enters the detec-
tion zone.
SSD1038
If the driver activates the turn signal, then
the BSW indicator light flashes and a
chime will sound twice.
NOTE:
If the driver activates the turn signal
before a vehicle enters the detection zone,
the BSW indicator light will flash but no
chime will sound when another vehicle is
detected.
BSW temporarily not available
When radar blockage is detected, the BSW
system will be turned off automatically, a
beep will sound and the BSW system
warning light will blink. The BSW systemis not available until the condition no
longer exists.
The radar sensors may be blocked by
temporary ambient conditions such as
splashing water, mist or fog. The blocked
condition may also be caused by objects
such as ice, frost or dirt obstructing the
radar sensors.
Action to take:
When the above condition no longer exists,
the BSW system will resume automatically.
If the warning light continues to blink, have
the BSW system checked by an INFINITI
retailer.
BSW MALFUNCTION
When the BSW system malfunctions, it will
be turned off automatically, a beep will
sound and the BSW system warning light
will illuminate.
Action to take:
Stop the vehicle in a safe location, turn the
engine off and restart the engine.
If the warning light continues to illuminate,
have the BSW system checked by an
INFINITI retailer.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control
mode, the Intelligent Cruise Control (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.
With ICC, the driver can maintain the same
speed as other vehicles without the con-
stant need to adjust the set speed as you
would with a normal cruise control system.
SSD0701
PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the distance sensor
*Adetects 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
25% of vehicle braking power) if neces- sary.
The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING
.
This system is only an aid to assist the
driver 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.
. 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 automatically
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.
The distance 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
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing 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 standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not detect the vehicle in
front of you in certain road or weather conditions. To avoid accidents, never use
the Intelligent Cruise Control system
under 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.)
When the windshield wiper is oper-
ated at the low speed (LO) or high
speed (HI) position, the Intelligent
Cruise Control system is automati-
cally canceled.
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere to
the system sensor
—On steep downhill roads (the vehi-cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
—On repeated uphill and downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
. 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 distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this
section.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance. The
vehicle-to-vehicle distance control mode of
the Intelligent Cruise Control (ICC) system
may not be able to maintain the selected
distance between vehicles (following dis-
tance) or selected vehicle speed under
some circumstances.
The vehicle-to-vehicle distance control
mode uses a sensor
*Alocated on the
front of the vehicle to detect vehicles traveling ahead. The sensor generally
detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if
the sensor cannot detect the reflector on
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:
.
When the reflector of the vehicle ahead
is positioned high on the vehicle
(trailer, etc.)
. When the reflector on the vehicle ahead
is missing, damaged or covered
. When the reflector of the vehicle ahead
is covered with dirt, snow and road
spray
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When dense exhaust or other smoke
(black smoke) from vehicles reduces
the sensor’s visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
room of your vehicle
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 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 dis-
tance 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.
The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match
the slower vehicle ahead. The system will
decelerate the vehicle as necessary and if
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill. How-
ever, the ICC system can only apply up to
25% of the vehicles total braking power.
This system should only be used when
traffic conditions allow vehicle speeds to
remain fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decele-
rates, the distance between vehicles may
become closer because the ICC system
cannot decelerate the vehicle quickly en-

5-42Starting and driving
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
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 traveling ahead.
SSD0254
When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC 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.

SSD0284A
NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects some reflectors
*A
which are fitted on vehicles in other lanes
or on the side of the road. This may cause
the ICC system to decelerate or accelerate
the vehicle. The ICC sensor may detect
these reflectors when the vehicle is driven
on winding roads, hilly roads or when
entering or exiting a curve. The ICC sensor
may also detect reflectors on narrow roads
or in road construction zones. 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 con-
ditions 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, DS
or Manual mode
. When the windshield wipers are operat-
ing at low (LO) or high speed (HI). If the
vehicle is equipped with a rain sensing
auto-wiper, the system may cancel
when the wipers are set to intermittent
(INT).
. When the parking brake is applied
. When the SNOW mode switch is turned
ON
. When the VDC system is turned off
. When ABS or VDC (including the trac-
tion control system) operates .
When driving into a strong light (for
example, sunlight)
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor
. When a wheel slips
