WARNING
Failure to follow the warnings and
instructions for proper use of the LDW
and LDP systems could result in serious
personal injury or death.
.The LDW and LDP systems will not
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 LDP system may activate if you
change lanes without first activating
your turn signal or, for example, if a
construction zone directs traffic to
cross an existing lane marker. If this
occurs, you may need to apply cor-
rective steering to complete your lane
change.
. Because the LDP system may not
activate under the road, weather,
and lane marker conditions described
in this section, it may not activate
every time your vehicle begins to
leave its lane and you will need to
apply corrective steering. .
Lane Departure Warning (LDW) system
— warns the driver with an indicator in the vehicle information display and
chime that the vehicle is beginning to
leave the driving lane.
. Lane Departure Prevention (LDP) system
— warns the driver with an indicator in the vehicle information display and
chime, and helps the driver to return
the vehicle to the center of the
traveling lane.
JVS1124X
The LDW and LDP systems use a camerainstalled behind the windshield to monitor
the lane markers of your traveling lane.

If the vehicle approaches either the left or
the right side of the traveling lane, the driver
assist system lane indicator (orange) in the
vehicle information display will blink and a
warning chime will sound.
NOTE:
The LDW system is not designed to warn
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.)

LDW/LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the LDW and LDP systems. Failure to
operate the vehicle in accordance with
these system limitations could result in
serious injury or death.
.The system will not operate at speeds
below 45 MPH (70 km/h) or if it
cannot detect lane markers.
. The LDP system is primarily intended
for use on well-developed freeways
or highways. It may not detect the
lane markers in certain roads, weath-
er or driving conditions.
. Do not use the LDP system under the
following conditions as it may not
function properly:
— During bad weather (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.
— When driving without normal tire conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-stan-
dard wheels).
— When the vehicle is equipped with non-original steering parts, brake
parts or suspension parts.
. The camera may not detect lane
markers in the following situations
and the LDW and LDP systems 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; non-standard 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 sha-

dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs. (The LDW and LDP
systems could detect these items
as lane markers.)
— On roads where the traveling lane merges or separates.
— When the vehicle’s traveling di- rection does not align with the
lane marker.
— 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 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 sun-
set.)
— When a sudden change in bright- ness occurs. (For example, when
the vehicle enters or exits a tunnel or under a bridge.)
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

SYSTEM MAINTENANCE
The lane camera unitfor LDW/LDP
systems is located above the inside mirror.
To keep the proper operation of LDW/LDP
systems 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. Do not touch the
camera lens or remove the screw located
on the camera unit. It is recommended
you contact an INFINITI retailer if the
camera unit is damaged due to an
accident.
WARNING
Failure to follow the warnings and
instructions for proper use of the BSW
system could result in serious injury or
death.
. The BSW system is not a replacement
for proper driving procedure and is
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 your vehicle will move to
ensure it is safe to change lanes.
Never rely solely on the BSW system.
. There is a limitation to the detection
capability of the radar. Not every
moving object or vehicle will be
detected. Using the BSW system
under some road, ground, lane mar-
ker, traffic or weather conditions
could lead to improper system opera-
tion. Always rely on your own opera-
tion to avoid accidents.
The BSW system helps alert the driver of
other vehicles in adjacent lanes when chan-
ging lanes.
JVS1122X
The BSW system uses radar sensorsinstalled near the rear bumper to detect
other vehicles in an adjacent lane.
