LANE DEPARTURE PREVENTION
(LDP) SYSTEM
Precautions on LDP system
WARNING
.The LDP system 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 vehicle at all
times.
. The LDP system is primarily intended for
use on well-developed freeways or high-
ways. It may not detect the lane markers
in certain roads, weather or driving
conditions.
. Using the LDP system under some
conditions of road, lane marker or
weather, or when you change lanes
without using the lane change signal
could lead to an unexpected system
operation. In such conditions, you need
to correct the vehicle’s direction with
your steering operation to avoid acci-
dents. .
When the LDP system is operating, avoid
excessive or sudden steering maneu-
vers. Otherwise, you could lose control
of the vehicle.
. The LDP system will not operate at
speeds below approximately 45 MPH
(70 km/h) or if it cannot detect lane
markers.
. The LDP system may not function
properly under the following conditions,
and do not use the LDP system:
—During bad weather (rain, fog, snow,
wind, etc.).
—When driving on slippery roads,
such as on ice or snow, etc.
—When driving off-road such as on sand or rock, etc.
—When driving on winding or uneven
roads.
—When there is a lane closure due toroad repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane 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 with
non-original brake parts or suspen-
sion parts.
—When towing a trailer or othervehicle.
. If the LDP system malfunctions, it will
cancel automatically. The lane departure
warning light (orange) on the instrument
panel will illuminate.
. If the lane departure warning 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 warning light (orange)
continues to illuminate, have the LDP
system checked by an INFINITI retailer.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
The functions of the LDP system (warning
and brake control assist) may or may not
operate properly under the following con-
ditions:

.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 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 LDP
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 or dirt adheres to the
windshield in front of the lane camera
unit.
. When the headlights are not bright due
to dirt on the lens or if the aiming is not
adjusted properly. .
When strong light enters the lane
camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.)
. When a sudden change in brightness
occurs. (For example, when the vehicle
enters or exits a tunnel or under a
bridge.)
While the LDP system is operating, you
may hear a sound of brake operation. This
is normal and indicates that the LDP
system is operating properly.

LDP system operation
The LDP system provides a lane departure
warning and brake control assistance when
the vehicle is driven at speeds of approxi-
mately 45 MPH (70 km/h) and above.
When the vehicle approaches either the left
or the right side of the traveling lane, a
warning chime will sound and the lane
departure warning light (orange) on the
instrument panel will blink to alert the
driver. Then, the LDP system will automa-
tically apply the brakes for a short period
of time to help assist the driver to return

Detection zone
The radar sensors can detect vehicles on
either side of your vehicle within the
detection zone shown as illustrated. This
detection zone starts from the outside
mirror of your vehicle and extends approxi-
mately 10 ft (3 m) behind the rear bumper,
and approximately 10 ft (3 m) sideways.
The BSW system operates above approxi-
mately 20 MPH (32 km/h). If the radar
sensors detect a vehicle in the detection
zone, the the Blind spot warning indicator
light illuminates. If the driver then acti-
vates the turn signal, a chime will sound
twice and the Blind spot warning indicator
light will flash. The Blind Spot Intervention
TMsystem
operates above approximately 37 MPH
(60 km/h). If the system detects a vehicle
in the detection zone and your vehicle is
approaching the lane marker, the Blind
Spot Intervention
TMsystem provides an
audible warning (three times), flashes the
Blind spot warning indicator light and
slightly applies the brakes for a short
period of time on one side to help return
the vehicle back to the traveling lane. The
Blind Spot Intervention
TMsystem provides
an audible warning and turns on or flashes
the Blind spot warning indicator light even
if the BSW system is off.
WARNING
. The BSW and Blind Spot InterventionTM
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 direction you will move
to ensure it is safe to change lanes.
Never rely solely on the BSW or Blind
Spot Intervention
TMsystem. .
Using the Blind Spot Intervention
TM
system under some road, lane marker
or weather conditions could lead to
improper system operation. Always rely
on your own steering and braking
operation to avoid accidents.
. The BSW and Blind Spot Intervention
TM
systems may not provide a warning or
brake control for vehicles that pass
through the detection zone quickly.

BLIND SPOT INTERVENTIONTMSYS-
TEM OPERATION
If the radar sensors detect vehicles in the
detection zone, the Blind spot warning
indicator light located inside the outside
mirrors illuminates. If your vehicle is
approaching a lane marker, the Blind spot
warning 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. Blind Spot Interven-
tion
TMoperates regardless of turn signal usage.
NOTE:
.
Warning and brake control will only be
activated if the Blind spot warning
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 brake control will be activated. (See
“BSW/Blind Spot Intervention
TMdriv-
ing situations” later in this section.)
. The Blind Spot Intervention
TMsystem is
typically activated earlier than the
Lane Departure Prevention (LDP) sys-
tem when your vehicle is approaching
a lane marker.
The Blind Spot Intervention
TMsystem 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 Blind Spot Intervention
TMON
indicator light (green) on the instrument
panel illuminates when the Blind Spot
Intervention
TMsystem is turned on.
The Blind Spot InterventionTMsystem
provides an audible warning and flashes the indicator light when Blind Spot Inter-
vention
TMis activated even if the BSW
system is off.

WARNING
.Do not use the Blind Spot InterventionTM
system under the following conditions
because the system may not function
properly.
—During bad weather (for example,
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 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.
. Do not use the BSW or Blind Spot
Intervention
TMsystems when towing a
trailer.
. 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 Blind Spot Interven-
tion
TM/BSW when certain objects are
present such as:
—Pedestrians, bicycles, animals
—Several types of vehicles such as motorcycles
—Oncoming vehicles
—Vehicles remaining in the detectionzone when you accelerate from a
stop
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle merging into an adjacent lane at a speed approximately the same as your vehicle
(See
“BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle approaching rapidly from behind.
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle which your vehicle over-
takes rapidly.
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
. Severe weather or road spray conditions
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 vehi-
cles 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, however ob-
jects such as guardrails, walls, foliage

If the driver activates the turn signal, then
the Blind spot warning indicator light
flashes and a chime will sound twice.
NOTE:
If the driver activates the turn signal
before a vehicle enters the detection zone,
the Blind spot warning indicator light will
flash but no chime will sound when the
other vehicle is detected.
