BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 MPH (32 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
illuminates.
If the turn signal is then activated, the
system chimes (twice) and the side indicator
light flashes. The side indicator light con-
tinues to flash until the detected vehicle
leaves the detection zone.
NOTE:
.The side indicator lights illuminate for a
few seconds when the ignition switch is
placed in the ON position.
. The brightness of the side indicator
lights is adjusted automatically depend-
ing on the brightness of the ambient
light.
. If a vehicle comes into the detection zone
after the driver activates the turn
signal, then only the side indicator light
flashes and no chime sounds. (See “BSW
driving situations” (P.5-43).)

Vehicle information display
SYSTEM TEMPORARILY UNA-
VAILABLE
When radar blockage is detected, the BSW
system will be turned off automatically, a
chime will sound and the “side radar ob-
struction” warning message will appear in
the vehicle information display
.
The system is not available until the condi-
tions no longer exist.
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 conditions no longer exist,
the system will resume automatically.
If the “side radar obstruction” warning
message continues to appear, have the
system checked. It is recommended you visit
an INFINITI retailer for this service.
SYSTEM MALFUNCTION
When the BSW system malfunctions, it will
be turned off automatically, a chime will
sound, and the system “malfunction” warn-
ing message with the driver assist system
blind spot indicator (orange) will appear in
the vehicle information display.
Action to take:
Stop the vehicle in a safe location and place
the shift lever in the P (Park) position. Turn
the engine off and restart the engine. If the
system “malfunction” warning message with
the driver assist system blind spot indicator
(orange) continues to be displayed, have the
BSW system checked. It is recommended
you visit an INFINITI retailer for this service.

BSI SYSTEM OPERATION
The BSI system operates above approxi-
mately 37 MPH (60 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
illuminates.
If the turn signal is then activated, the
system chimes (twice) and the side indicator
light flashes. The side indicator light con-
tinues to flash until the detected vehicle
leaves the detection zone.
If the BSI system is ON and your vehicle
approaches a lane marker while another
vehicle is in the detection zone, the system
chimes (three times) and the side indicator
light flashes. The BSI system activates to
help return the vehicle back to the center of
the driving lane. The BSI system operates
regardless of turn signal usage.
NOTE:
.BSI warning and system application will
only be activated if the side indicator
light is already illuminated when your
vehicle approaches a lane marker. If
another vehicle comes into the detection
zone after your vehicle has crossed a
lane marker, no BSI warning or system
application will be activated. (For addi-
tional information, see “BSI driving
situations” (P.5-53).)

(models without Direct Adaptive
Steering)
— When the vehicle is accelerated dur-
ing BSI system operation
— When steering quickly

are operated.
— When driving on a curve at a high
speed.

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
ICC system display. Decelerate by depres-
sing the brake pedal to maintain a safe
vehicle distance if:
.The chime sounds.
. The vehicle ahead detection indicator and
set distance indicator blink.
The warning chime may not sound in some
cases when there is a short distance be-
tween 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 condi-
tions and the control is automatically can-
celed.
.
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
position or Manual mode
. When the parking brake is applied
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode .
When the VDC system is turned off
. When ABS or VDC (including the traction
control system) operates
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor
. When a wheel slips
. When the radar signal is temporarily
interrupted

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 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 con-
gested areas.
. This system will not adapt automati-
cally 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
