SYSTEM MAINTENANCE
The two radar sensorsfor the BSI system
are located near the rear bumper. Always
keep the area near the radar sensors clean.
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.
Check for and remove objects obstructing
the area around the radar sensors.
Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors.

Do not strike or damage the area around the
radar sensors.
It is recommended you visit an INFINITI
retailer if the area around the radar sensors
is damaged due to a collision.
The lane camera unit
for BSI system is
located above the inside mirror. To keep the
proper operation of BSI and prevent a
system malfunction, be sure to observe the
following:
. Always keep the windshield clean.
. Do not attach a sticker (including trans-
parent material) or install an accessory
near the camera unit.
. Do not place reflective materials, such as
white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.
. Do not strike or damage the areas around
the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit. It is recommended
you contact an INFINITI retailer if the

WARNING
Failure to follow the warnings and
instructions for proper use of the BCI
system could result in serious injury or
death.
.The BCI system is not a replacement
for proper driving procedure, is not
designed to prevent contact with
vehicles or objects and does not
provide full brake power. When back-
ing out of parking spaces, always use
the inside and rear mirrors and turn
and look in the direction you will
move. Never rely solely on the BCI
system.
. There is a limitation to the detection
capability of the radar or the sonar.
Using the BCI system under some
road, ground, traffic or weather con-
ditions could lead to improper system
operation. Always rely on your own
operation to avoid accidents.
The BCI system can help alert the driver of
an approaching vehicle or objects behind the
vehicle when the driver is backing out of a
parking space.
JVS1121X
The BCI system uses radar sensorsinstalled on both sides near the rear bumper
to detect an approaching vehicle and sonar
sensors
to detect objects in the rear.

BACK-UP COLLISION
INTERVENTION (BCI) (if so equipped)

The radar sensorsdetect an approaching
vehicle from up to approximately 49 ft (15
m) away. The sonar sensors
detect
stationary objects behind the vehicle up to
approximately 4.9 ft (1.5 m). Refer to the
illustration for approximate zone coverage
areas

NOTE:
.In the case of several vehicles approach-
ing in a row (Illustration 1) or in the
opposite direction (Illustration 2), a
chime may not be sounded by the BCI
system after the first vehicle passes the
sensors.
. The sonar system chime indicating there
is an object behind the vehicle has a
higher priority than the BCI chime
(single beep) indicating an approaching
vehicle. If the sonar system detects an
object behind the vehicle and the BCI
system detects an approaching vehicle
at the same time, the following indica-
tions are provided:
— The sonar system chime sounds
— The side indicator light on the side of
the approaching vehicle flashes, and
— A yellow rectangular frame appears
in the display.
JVS0307X
If an approaching vehicle or object behind
the vehicle is detected when your vehicle is
backing up, a red frame
will appear on the
upper display and the system will chime
three times. Then, the brakes will be applied
momentarily. After the automatic brake
application, the driver must depress the
brake pedal to maintain brake pressure.
If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward before the braking is applied.
However, if you continue to accelerate, the
system will not engage the brakes.
The BCI system does not operate if the
object is very close to the bumper.

BCI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BCI system. Failure to operatethe vehicle in accordance with these
system limitations could result in serious
injury or death.
.
Always check your surroundings and
turn to check what is behind you
before backing up. .
The radar sensors detect approach-
ing (moving) vehicles. The radar sen-
sors cannot detect every object such
as:
— Pedestrians, bicycles, animals or child operated toy vehicles
— A vehicle that is passing at speeds greater than approximately 15
MPH (24 km/h)
. The radar sensors may not detect
approaching vehicles in certain situa-
tions:
— Illustration a. When a vehicle parked next to you obstructs the
beam of the radar sensor.
— Illustration b. When the vehicle is parked in an angled parking space.
— Illustration c. When the vehicle is parked on inclined ground.
— Illustration d. When an approach- ing vehicle turns into your vehi-
cle’s parking lot aisle.
— Illustration e. When the angle formed by your vehicle and ap-
proaching vehicle is small.
. The following conditions may reduce
the ability of the radar sensors to
detect other vehicles:
Starting and driving5-69

5-70Starting and driving
— Severe weather
— Road spray
— Ice/frost/dirt build up on thevehicle
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar
sensors to detect other vehicles.
. The sonar sensors detect stationary
objects behind the vehicle. The sonar
sensor may not detect:
— Small or moving objects
— Wedge-shaped objects
— Object close to the bumper (less than approximately 1 ft (30 cm))
— Thin objects such as rope, wire and chain, etc.
. The brake engagement by the BCI
system is not as effective on a slope
as it is on flat ground. When on a
steep slope the system may not
function properly.
. Do not use the BCI system under the
following conditions because the sys-
tem may not function properly. — When driving with a tire that is
not within normal tire conditions
(for example, tire wear, low tire
pressure, installation of spare tire,
tire chains, non-standard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.
