When the “[X]” icon is displayed on the
screen, the camera image may be receiving
temporary electronic disturbances from sur-
rounding devices. This will not hinder normal
driving operation but the system should be
inspected. It is recommended that you visit an
INFINITI retailer for this service.SYSTEM MAINTENANCE
CAUTION
∙ Do not use alcohol, benzine or thinner toclean the camera. This will cause
discoloration.
∙ Do not damage the cameras as the moni- tor screen may be adversely affected.
If dirt, rain or snow accumulates on any of the
cameras
1, the Around View® Monitor may
not display objects clearly. Clean the camera
by wiping with a cloth dampened with a di-
luted mild cleaning agent and then wiping
with a dry cloth.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar function as
outlined in this section could result in seri-
ous injury or death.
∙ The sonar is a convenience feature. It is not a substitute for proper parking.
∙ This function is designed as an aid to the driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
∙ The driver is always responsible for safety during parking and other
maneuvers.
∙ Always look around and check that it is safe to move before parking.
∙ Read and understand the limitations of the sonar as contained in this section.
The sonar function helps to inform the driver
of large stationary objects around the vehicle
when parking by issuing an audible and visual
alert.

SONAR SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the sonar function. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
∙ Inclement weather or ultrasonic sources such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem, including reduced performance or a
false activation.
∙ The system is not designed to prevent contact with small or moving objects.LHA4609LHA4610
Monitor, climate, audio, phone and voice recognition systems4-27

∙ The system will not detect small objectsbelow the bumper, and may not detect
objects close to the bumper or on the
ground.
∙ The system may not detect the following objects:
– Fluffy objects such as snow, cloth, cotton, grass or wool.
– Thin objects such as rope, wire or chain.
– Wedge-shaped objects.
∙ If your vehicle sustains damage to the bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
jects or false alarms.
CAUTION
Excessive noise (such as audio system vol-
ume or an open vehicle window) will inter-
fere with the tone and it may not be heard.
System temporarily unavailable
When the amber markers are displayed at the
corners of the vehicle icon and the function
cannot be activated from the Camera setting
menu (the setting items are grayed out), the
sonar system may be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors (lo-
cated on the front and rear bumper fascia)
free from accumulations of snow, ice and
dirt. Do not scratch the surface of the sonar
sensors when cleaning. If the sensors are
covered, the accuracy of the sonar function
will be diminished.

Failure to follow the warnings and instruc-
tions for proper use of the BSI system could
result in serious injury or death.
∙ The BSI system is not a replacement forproper driving procedure and is not de-
signed to prevent contact with vehicles
or objects. When changing lanes, always
use the side and rear mirrors and turn and
look in the direction you will move to en-
sure it is safe to change lanes. Never rely
solely on the BSI system.
∙ There is a limitation to the detection ca- pability of the radar or the sonar. Not
every moving object or vehicle will be de-
tected. Using the BSI system under some
road, ground, lane marker, traffic or
weather conditions could lead to im-
proper system operation. Always rely on
your own operation to avoid accidents.
The BSI system helps alert the driver of other
vehicles in adjacent lanes when changing
lanes and helps assist the driver to return the
vehicle to the center of the traveling lane. The BSI system uses radar sensors
2in-
stalled near the rear bumper to detect other
vehicles in an adjacent lane. In addition to the
radar sensors, the BSI system uses a camera
1installed behind the windshield to monitor
the lane markers of your traveling lane.
The radar sensors can detect vehicles on ei-
ther side of your vehicle within the detection
zone shown as illustrated. This detection
zone starts from the outside mirror of your
vehicle and extends approximately 10 ft
(3.0 m) sideways.

∙ There is a limitation to the detection ca-pability of the radar or the sonar. Using
the BCI systems under some road,
ground, lane marker, traffic or weather
conditions could lead to improper system
operation. Always rely on your own op-
eration to avoid accidents.
The BCI system can help alert the driver of an
approaching vehicle or objects behind the ve-
hicle when the driver is backing out of a park-
ing space.
The BCI system uses radar sensors
1in-
stalled on both sides near the rear bumper to
detect an approaching vehicle and sonar sen-
sors to detect objects in the rear.
The radar sensors
1detect an approaching
vehicle from up to approximately 49 ft (15 m)
away. The sonar sensors
2detect stationary
objects behind the vehicle up to approxi-
mately 4.9 ft (1.5 m)

5-66Starting and driving

If the radar detects an approaching vehicle
from the side, the system chimes a sound
(single beep), the side indicator light on the
side of the approaching vehicle flashes and a
yellow rectangular frame appears in the dis-
play
A.NOTE:
∙ In the case of several vehicles approach-
ing in a row (Illustration 1) or in the op-
posite 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 ap-
proaching vehicle at the same time the fol-
lowing indicators 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
If an approaching vehicle or object behind the
vehicle is detected when your vehicle is back-
ing up, a red frame will appear in the display
Aand 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 main-
tain brake pressure.

formed by your vehicle and approach-
ing vehicle is small.
∙ The radar sensors are designed to ignore most stationary objects; however, ob-
jects such as guardrails, walls, foliage and
parked vehicles may occasionally be de-
tected. This is a normal operation
condition.
∙ The following conditions may reduce the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/dirt build up on the vehicle
∙ Do not attach stickers (including trans- parent material), install accessories or
apply additional paint near the radar sen-
sors. These conditions may reduce the
ability of the radar to detect other
vehicles. ∙ The sonar sensors detect stationary ob-
jects behind the vehicle. The sonar sensor
may not detect:
– Small or moving objects
– Wedge-shaped objects
– Objects 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 sys-
tem may not function properly.
∙ Do not use the BCI system under the fol- lowing conditions because the system
may not function properly:
– When driving with a tire that is not within normal tire conditions (e.g., 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 suspen-
sion parts.
∙ Do not use the BCI system when towing a trailer. ∙ Excessive noise (e.g., audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.
SYSTEM TEMPORARILY NOT
AVAILABLE
If the following messages appear on the ve-
hicle information display, a chime will sound
and the BCI system will be turned off auto-
matically:
∙ “Unavailable: High Accelerator Temp.”: If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then
started, the BCI system may be deacti-
vated automatically and the “Unavailable:
High Accelerator Temp” message will ap-
pear in the vehicle information display for
a period of time.
When the interior temperature is re-
duced, turn off the BCI system and turn it
on again.
∙ “Unavailable: Side Radar Obstruction”: When side radar blockage is detected.
When the blockage is removed, turn off
the BCI system and turn it on again.
