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.)

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. .
