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. Then the BSI system slightly
applies the brakes to help return the vehicle
back to the center of the driving lane. The
BSI system operates regardless of turn
signal usage.
NOTE:
.Warning and system application of the
brakes 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 warning or
system application of the brakes will be
activated. (See “BSI driving situations”

BSI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSI system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.The BSI system cannot detect all
vehicles under all conditions.
. The radar sensors may not be able to
detect and activate BSI when certain
objects are present such as:
— Pedestrians, bicycles, animals.
— Vehicles such as motorcycles, low height vehicles, or high ground
clearance vehicles.
— Vehicles remaining in the detec- tion zone when you accelerate
from a stop.
— Oncoming vehicles.
— A vehicle merging into an adja- cent lane at a speed approxi-
mately the same as your vehicle.
— A vehicle approaching rapidly from behind. — A vehicle which your vehicle over-
takes rapidly.
— A vehicle that passes through the detection zone quickly.
. The radar sensor’s 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 oc-
casionally be detected. This is a
normal operation condition.
. The camera may not detect lane
markers in the following situations
and the BSI system may not operate
properly.
— On roads where there are multi- ple parallel lane markers; lane
markers that are faded or not
painted clearly; yellow painted
lane markers; non-standard lane
markers; lane markers covered
with water, dirt, snow, etc.

cally canceled.
. When the vehicle slows down more than
8 MPH (13 km/h) below the set speed
. When the shift lever is shifted to the N
(Neutral) position
. When the parking brake is applied
. When the VDC (including the traction
control system) operates.
. When a wheel slipsJVS0661X
Warning light
When the system is not operating properly,
the chime sounds and the system warning
light (orange) will come on.
Action to take:
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, resume driving and then
perform the setting again.
If it is not possible to set or the indicator
stays on, it may indicate that the system is
malfunctioning. Although the vehicle is still
driveable under normal conditions, have the
vehicle checked. It is recommended you visit
an INFINITI retailer for this service.
WARNING
Failure to follow the warnings and
instructions for proper use of the DCA
system could result in serious personal
injury or death.
.Always drive carefully and atten-
tively when using the DCA system.
Read and understand the Owner’s
Manual thoroughly before using the
DCA system. To avoid serious injury
or death, do not rely on the system to
prevent accidents or to control the
vehicle’s speed in emergency situa-
tions. Do not use the DCA system
except in appropriate road and traffic
conditions.
. 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.
. As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive or absent-minded driving, or
overcome poor visibility in rain, fog,
or other bad weather. Decelerate the

vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
. Always pay attention to the opera-
tion of the vehicle and be ready to
manually decelerate to maintain the
proper following distance. The DCA
system may not be able to decelerate
the vehicle under some circum-
stances.
. This system only brakes and moves
the accelerator pedal upward to help
assist the driver to maintain a follow-
ing distance from the vehicle ahead.
Acceleration should be operated by
the driver.
. The DCA system does not control
vehicle speed or warn you when you
approach stationary and slow moving
vehicles. You must pay attention to
vehicle operation to maintain proper
distance from vehicles ahead.
. The DCA system automatically de-
celerates your vehicle to help assist
the driver to maintain a following
distance from the vehicle ahead.
Manually brake when deceleration is
required to maintain 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 DCA system.
. If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel 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.

The DCA system is intended to assist the
driver in keeping a following distance from
the vehicle ahead traveling in the same lane
and direction.
If the radar sensor
detects a slower
moving vehicle ahead, the system will reduce
the vehicle speed to help assist the driver to
maintain a following distance.
The system automatically controls the throt-
tle and applies the brakes (up to approxi-
mately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.

DCA SYSTEM OPERATION
WARNING
Failure to follow the warnings and
instructions for proper use of the DCA
system could result in serious personal
injury or death.
.When the vehicle ahead detection
indicator light is not illuminated,
system will not control the vehicle
or warn the driver.
. Never place your foot under the
brake pedal. Your foot may be caught
when the system controls the brake.
. Depending on the position of the
accelerator pedal, the system may
not be able to assist the driver to
release the accelerator pedal appro-
priately.
The DCA system brakes and moves the
accelerator pedal upward according to the
distance from and the relative speed of the
vehicle ahead to help assist the driver in
maintaining a following distance. The sys-
tem will decelerate as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the
DCA system can only apply up to approxi-

mately 40% of the vehicle’s total braking
power. If a vehicle moves into the traveling
lane ahead or if a vehicle traveling ahead
rapidly decelerates, the distance between
vehicles may become closer because the
DCA system cannot decelerate the vehicle
quickly enough. If this occurs, the DCA
system will sound a warning chime and blink
the system display to notify the driver to
take necessary action.
See “Approach warning” (P.5-91).

The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelera-
tor pedal upward in the normal driving
condition.
When a vehicle ahead is detected:
The vehicle ahead detection indicator comes
on.
When the vehicle approaches a vehicle
ahead:
. If the driver’s foot is not on the accel-
erator pedal, the system activates the brakes to decelerate smoothly as neces-
sary. If the vehicle ahead comes to a
stop, the vehicle decelerates to a stand-
still within the limitations of the system.
. If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward to assist the driver to
release the accelerator pedal.
When brake operation by the driver is
required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead detec-
tion indicator. If the driver’s foot is on the
accelerator pedal after the warning, the
system moves the accelerator pedal upward
to assist the driver to switch to the brake
