ACTIVE LANE CONTROL LIM-
ITATIONS
WARNING
Listed below are the limitations for
Active Lane Control. Failure to operate
the vehicle in accordance with these
limitations could result in serious injury
or death.
.Active Lane Control is primarily in-
tended for use on well-developed
freeways or highways. It may not
detect the lane markers for certain
roads, weather or driving conditions.
. Using Active Lane Control under
some conditions of road, lane marker
or weather, or if you attempt to
change lanes without using the lane
change signal could lead to an un-
expected system operation. In such
conditions, you need to correct the
vehicle’s direction with your steering
operation to avoid accidents.
. Active Lane Control will not operate
at speeds below approximately 45 MPH (70 km/h) or if it cannot detect
lane markers.
. Active Lane Control may not operate
properly and should not be used
under the following conditions:
— 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 lane.
— When driving on roads where the lane width is too narrow.
— 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 steering parts or sus-
pension parts.
. Active Lane Control may or may not
operate properly under the following
conditions: — 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. (Active Lane Control
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, dirt or object adheres to the windshield in front

SYSTEM MAINTENANCE
The lane camera unitfor Active Lane
Control is located above the inside mirror. To
keep the proper operation of Active Lane
Control 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 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
vibrations of the steering wheel that
the vehicle is beginning to leave the
driving lane.
. Lane Departure Prevention (LDP) system
(if so equipped)
— warns the driver with an indicator in the vehicle information display and
vibrations of the steering wheel, and
helps the driver to return the vehicle
to the center of the traveling lane.

WARNING
Failure to follow the warnings and
instructions for proper use of the BSI
system could result in serious injury or
death.
.The BSI system is not a replacement
for proper driving procedures 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 BSI system.
. There is a limitation to the detection
capability of the radar. Not every
moving object or vehicle will be
detected. Using the BSI system under
some road, ground, lane marker,
traffic or weather conditions could
lead to improper system operation.
Always rely on your own operation to
avoid accidents.
The BSI system helps alert the driver of other
vehicles in adjacent lanes when changing
lanes, and helps assist the driver to return
the vehicle to the center of the traveling
lane.
JVS1125X
The BSI system uses radar sensorsinstalled near the rear bumper to detect
other vehicles in an adjacent lane. In addition
to the radar sensors, the BSI system uses a
camera
installed behind the windshield to
monitor the lane markers of your traveling
lane.
SSD1030
Detection zone
The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion 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.
