WARNING
.This system is only a warning device to
inform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or prevent loss of control. It
is the driver’s responsibility to stay
alert, drive safely, keep the vehicle in
the traveling lane, and be in control of
the vehicle at all times.
. The system will not operate at speeds
below approximately 45 MPH (70 km/h)
or if it cannot detect lane markers.
. If the LDW system malfunctions, it will
cancel automatically, and the LDW light
(orange) will illuminate.
. If the LDW light (orange) illuminates,
pull off the road to a safe location and
stop the vehicle. Turn the engine off and
restart the engine. If the LDW light
(orange) continues to illuminate, have
the system checked by an INFINITI
retailer. .
Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
. Do not use the LDW system under the
following conditions as it may not
function properly:—During bad weather (rain, fog, snow,
wind, etc.).
—When driving on slippery roads,such as on ice or snow, etc.
—When driving on winding or uneven roads.
—When there is a lane closure due toroad repairs.
—When driving in a makeshift ortemporary lane.
—When driving on roads where the lane width is too narrow.
—When driving without normal tireconditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-standard
wheels).
—When the vehicle is equipped withnon-original brake parts or suspen-
sion parts.
The system may not function properly
under the following conditions:
. On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-stan-
dard lane markers; or lane markers
covered with water, dirt, snow, etc.
. On roads where the discontinued lane
markers are still detectable.
. On roads where there are sharp curves.
. On roads where there are sharply
contrasting objects, such as shadows,
snow, water, wheel ruts, seams or lines
remaining after road repairs. (The LDW
system could detect these items as
lane markers.)
. On roads where the traveling lane
merges or separates.
. When the vehicle’s traveling direction
does not align with the lane marker.
. When traveling close to the vehicle in
front of you, which obstructs the lane
camera unit detection range.
. When rain, snow, dirt or object adheres
to the windshield in front of the lane
camera unit.

LDW system operationY51D-V-E01-2391B14F-5202-4D89-899F-8F7E17F895CDThe LDW system provides a lane departure
warning function when the vehicle is driven
at speeds of approximately 45 MPH (70
km/h) and the lane markings are clear.
When the vehicle approaches either the left
or the right side of the traveling lane, a
warning chime will sound and the LDW
light (orange) on the instrument panel will
blink to alert the driver.
The warning function will stop when the
vehicle returns inside of the lane markers.
The LDW system is not designed to warn
under the following conditions. .
When you operate the lane change
signal and change traveling lanes in
the direction of the signal. (The LDW
system will become operable again
approximately 2 seconds after the lane
change signal is turned off.)
. When the vehicle speed lowers to less
than approximately 45 MPH (70 km/h).
. When the Blind Spot Intervention
TM
(BSI) system activates an audible warn-
ing or brake control.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the LDW functions will resume.

5-34Starting and driving
The BSI system operates above approxi-
mately 37 MPH (60 km/h). If the system
detects a vehicle in the detection zone and
your vehicle is approaching the lane
marker, the BSI system provides an audi-
ble warning (three times), flashes the
BSW/BSI indicator light and slightly ap-
plies the brakes for a short period of time
on one side to help return the vehicle back
to the traveling lane. The BSI system
provides an audible warning and turns on
or flashes the BSW/BSI indicator light even
if the BSW system is off.
WARNING
.The BSW and BSI systems are not a
replacement for proper driving procedure
and are not designed to prevent contact
with vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the direc-
tion you will move to ensure it is safe to
change lanes. Never rely solely on the
BSW or BSI system.
. Using the BSI system under some road,
lane marker or weather conditions could
lead to improper system operation. Al-
ways rely on your own steering and braking operation to avoid accidents.
. The BSW and BSI systems may not
provide a warning or brake control for
vehicles that pass through the detection
zone quickly.

light located by the outside mirrors illumi-
nates. If the turn signal is then activated,
the BSW/BSI indicator light flashes and a
chime sounds twice. The indicator light
continues to flash until the detected
vehicles leave the detection zone.

BSI SYSTEM OPERATIONY51D-V-E01-96B4C4EA-DE72-44A7-840F-25C8167EECC1If the radar sensors detect vehicles in the
detection zone, the BSW/BSI indicator
light located by the outside mirrors illumi-
nates. If your vehicle is approaching a lane
marker, the BSW/BSI indicator light
flashes and an audible warning will sound
three times. Then the system applies the
brakes on one side of the vehicle for a
short period of time to help return the
vehicle back to the center of the lane. BSI
operates regardless of turn signal usage.NOTE:
.
Warning and system application of the
brakes will only be activated if the
BSW/BSI indicator light is already
illuminated when your vehicle ap-
proaches a lane marker. If another
vehicle comes into the detection zone
after your vehicle has crossed a lane
marker, no warning or brake applica-
tion will be activated. (See “BSW/BSI
driving situations” (P.5-40).)
. The BSI system is typically activated
earlier than the Lane Departure Pre-
vention (LDP) system when your vehi-
cle is approaching a lane marker.
The BSI system turns on when the dynamic
driver assistance switch on the steering
wheel is pushed when the “Blind Spot
Intervention” is enabled in the settings
menu on the center display. The BSI ON
indicator light (green) on the instrument
panel illuminates when the BSI system is
turned on.
The BSI system provides an audible warn-
ing and flashes the indicator light when
BSI is activated even if the BSW system is
off.

—When driving on slippery roads,such as on ice or snow, etc.
—When driving on winding or uneven roads.
—When there is a lane closure due to
road repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane width is too narrow.
—When driving with a tire that is notwithin normal tire conditions (for
example, tire wear, low tire pressure,
installation of spare tire, tire chains,
non-standard wheels).
—When the vehicle is equipped withnon-original brake parts or suspen-
sion parts.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound, and
it may not be heard.
.The radar sensors may not be able to
detect and activate BSI/BSW when
certain objects are present such as: —
Pedestrians, bicycles, animals
— Vehicles such as motorcycles, low
height vehicles, or high ground
clearance vehicles
— Oncoming vehicles
— Vehicles remaining in the detection
zone when you accelerate from a
stop
(See “BSW/BSI driving situations”
(P.5-40))
— A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle

(P.5-40))
— A vehicle which your vehicle over-
takes rapidly.
(See “BSW/BSI driving situations”

. Severe weather or road spray condi-
tions may reduce the ability of the
radar to detect other vehicles.
. The radar sensors 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 occa-
sionally be detected. This is a normal
operating condition.
. The camera may not detect lane mar-
kers in the following situations and the
BSI system may not operate properly.
— On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-
standard lane markers; lane mar-
kers 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.
