LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
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 lane de-
parture warning light (orange) will illu-
minate.
. 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 lane departure warning
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.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 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.)

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 lane departure warning 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.
When you operate the lane change signal
and change traveling lanes in the direction
of the signal, the LDW system temporarily
suspends operation. It will become oper-
able 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), the LDW
system will not provide a warning.
The LDW system has an automatic setting
mode and a manual setting mode. The
setting mode can be changed. In the
automatic setting mode, the LDW system
is automatically turned on when the igni-
tion switch is pushed to the ON position.
When the LDW system is on, the warning

when the warning systems ON indicator is
off. When the mode is changed, a chime
sounds and the lane departure warning
light (orange) flashes.
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 lane departure
warning light (orange) on the switch will flash.
When the interior temperature is reduced,
the LDW system will resume operating
automatically and the warning systems
ON indicator will stop flashing.
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 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 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
nonoriginal brake parts or suspen-
sion parts.
. 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.

LANE CAMERA UNIT MAINTENANCE
The lane camera unit*1for the LDW/LDP
system is located inside the map light
cover. To keep the proper operation of the
LDW/LDP systems and prevent a system
malfunction, be sure to observe the follow-
ing:
. Always keep the windshield clean.
. Do not attach a sticker (including
transparent material) or install an
accessory near the camera unit.
. Do not place reflective materials, such
as white paper or a mirror, on the
instrument panel. The reflection of sunlight may adversely affect the cam-
era unit’s capability of detecting the
lane markers.
. Do not strike or damage the areas
around the camera unit. Do not touch
the camera lens or remove the screw
located on the camera unit. If the
camera unit is damaged due to an
accident, contact an INFINITI retailer. The Blind Spot Warning (BSW) system can
help alert the driver of other vehicles in
adjacent lanes when changing lanes.
Starting and driving5-27
BLIND SPOT WARNING (BSW) SYSTEM (if
so equipped)

5-28Starting and driving
SSD1155
The BSW system uses radar sensors*A
installed near the rear bumper to detect
other vehicles beside your vehicle in an
adjacent lane.
SSD1030
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 (3.0 m) behind the rear
bumper, and approximately 10 ft (3.0 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 BSW indicator light illuminates. If
the driver then activates the turn signal, a
chime will sound twice and the BSW
indicator light will flash.
WARNING
. The BSW system is not a replacement for
proper driving procedure and is not
designed to prevent contact with vehi-
cles 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
system.
. The BSW system may not provide a
warning for vehicles that pass through
the detection zone quickly.

BSW SYSTEM OPERATION
If the radar sensors detect a vehicle in the
detection zone, the BSW indicator light
next to the outside mirror will illuminate in
the direction of the detected vehicle. If the
turn signal is then activated, the BSW
indicator light flashes and a chime sounds
twice. The indicator light continues to flash
until the detected vehicle leaves the
detection zone.
The BSW indicator lights illuminate for a
few seconds when the ignition switch is
pushed to the ON position.The brightness of the BSW indicator lights
is adjusted automatically depending on the
brightness of the ambient light.
A chime sounds if the radar sensors have
already detected vehicles when the driver
activates the turn signal. If a vehicle comes
into the detection zone after the driver
activates the turn signal, then only the
BSW indicator light flashes and no chime
sounds. (See
“BSW driving situations” (P.5-
30).)
The BSW system is automatically turned on
when the engine is started and the warning
systems ON indicator light
*1illuminates
on the switch. You can turn the BSW system
off by pushing the warning systems switch
on the instrumental panel. This switch will
turn on and off the LDW, BSW and FCW
systems at the same time.
NOTE:
If you continue to push the warning
systems switch from off to on for over 4
seconds, a chime will sound. This will
change the default status of the LDW, BSW
and FCW systems to OFF so that these
systems will not automatically turn on
when the engine is started. If this proce-
dure is repeated, the default status will
Starting and driving5-29

5-30Starting and driving
return to ON.
WARNING
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 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
(See “BSW driving situations” (P.5-
30).)
— A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle
(See “BSW driving situations” (P.5-
30).)
— A vehicle approaching rapidly from
behind. (See
“BSW driving situations” (P.5-
30).)
— A vehicle which your vehicle over-
takes rapidly.
(See “BSW driving situations” (P.5-
30).)
. 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.

BSW DRIVING SITUATIONS
Another vehicle approaching from
behind
The BSW indicator light illuminates if a
vehicle enters the detection zone from
behind in an adjacent lane.
However, if the overtaking vehicle is
traveling much faster than your vehicle,
the indicator light may not illuminate
before the detected vehicle is beside your
vehicle. Always use the side and rear
mirrors and turn and look in the direction
your vehicle will move to ensure it is safe
to change lanes.
