sensor INFINITI Q60 COUPE 2018 Service Manual

— 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 situationsand 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; nonstandard lane
markers; lane markers covered
with water, dirt, snow, etc.
— On roads where discontinued lane
markers are still detectable.
— On roads where there are sharp
curves.
— On roads where there are sharply
contrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs.
— On roads where the traveling lane
merges or separates.
— When the vehicle’s traveling di-
rection does not align with the
lane markers.
— When traveling close to the ve-
hicle in front of you, which ob-
structs the lane camera unit
detection range.
— When rain, snow or dirt adheres
to the windshield in front of a lanecamera unit.
— When the headlights are not
bright due to dirt on the lens or
if aiming is not adjusted properly.
— When strong light enters a lane
camera unit. (For example: light
directly shines on the front of the
vehicle at sunrise or sunset.)
— When a sudden change in bright-
ness occurs. (For example: when
the vehicle enters or exits a tunnel
or under a bridge.)
.Do not use the BSI system under the
following conditions because the sys-
tem may not function properly.
— During bad weather. (For exam-
ple: rain, fog, snow, etc.)
— When driving on slippery roads,
such as on ice or snow, etc.
— When driving on winding or un-
even roads.
— When there is a lane closure due
to road repairs.
— When driving in a makeshift or
temporary lane.
— When driving on roads where the
lane width is too narrow.

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. It is recommended you
contact an INFINITI retailer if the cam-
era unit is damaged due to an accident.

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.
JVS0866X
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.

5-62Starting and driving
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

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.
