Driver assist system lane indicator
LDW system operation
The LDW system provides a lane departure
warning function when the vehicle is driven
at speeds of approximately 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 driver assist system lane
indicator (orange) in the vehicle informa-
tion display 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 steering control.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the LDW functions will resume.
Temporary disabled status at high
temperature
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 1048 F (408C) and then
started, the LDW system may be deacti-
vated automatically. The high cabin tem-
perature warning message will appear in
the vehicle information display.
When the interior temperature is reduced,
the LDW system will resume operating
automatically.

LANE DEPARTURE PREVENTION
(LDP) SYSTEM
Precautions on LDP system
WARNING
.The LDP system will not always steer the
vehicle to keep it in the lane. It is not
designed to 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 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 with
non-original steering parts or sus-
pension parts.
. If the LDP system malfunctions, it will
cancel automatically. The LDP “malfunc-
tion” message will appear in the vehicle
information display.
. If the “malfunction” message appears,
pull off the road to a safe location and
stop the vehicle. Turn the engine off and
restart the engine. If the “malfunction”
message continues to appear, 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 steering 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; lane markers cov-

.The radar sensors may not be able to
detect and activate BSI/BSW when
certain objects are present such as:
— Pedestrians, bicycles, animals
— Several types of vehicles such as
motorcycles
— Oncoming vehicles
— Vehicles remaining in the detection
zone when you accelerate from a
stop
— A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle
— A vehicle approaching rapidly from
behind.
— A vehicle which your vehicle over-
takes rapidly.
See also “BSW/BSI driving situations”
(P.5-43) for the situations in which the
radar sensors may not be able to detect
vehicle(s).
. 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. —
On roads where the traveling lane
merges or separates.
— When the vehicle’s traveling direc-
tion does not align with the lane
markers.
— 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 a lane
camera 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.)

.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 systems under the
following conditions because the system
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 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.
BCI temporarily not available
When the following message appears in
the vehicle information display, a chime
will sound and the BCI system will be
turned off automatically. .

detects that the internal motor tem-
perature is high.
Action to take:
Turn on the BCI system again when the
above condition no longer exists.
. “Unavailable Side Radar Obstruction”:
When side radar blockage is detected.
Action to take:
If the warning message appears, park
the vehicle in a safe place, turn the
engine off. Check for and remove
objects obscuring the radar sensors
on the rear bumper, and restart the
engine. If the BSW or BSI system
operates normally, the BCI system will
also operate normally. (See “BSW/BSI
temporarily not available” (P.5-47).)
