Lane departure warning light (orange)
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.
The LDW system is not designed to warnunder 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 (BSI)
system activates an audible warning or
brake control.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the LDW functions will resume.

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 with a tire that is notwithin normal tire conditions (for
example, tire wear, low tire pres-
sure, installation of spare tire, tire

chains, non-standard wheels).
—When the vehicle is equipped withnonoriginal 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; lane markers cov- ered 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.

LDP system operation
The LDP system provides a lane departure
warning and brake control assistance when
the vehicle is driven at speeds of approxi-
mately 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. Then, the LDP system will automa-
tically apply the brakes for a short period
of time to help assist the driver to return the vehicle to the center of the traveling
lane.
The warning and assist functions will stop
when the vehicle returns to a position
inside of the lane marker.

Automatic deactivation
Condition A:
The warning and assist functions of the
LDP system are not designed to work under
the following conditions:
Starting and driving5-29

5-30Starting and driving

signal and change the traveling lanes
in the direction of the signal. (The LDP
system will be deactivated for approxi-
mately 2 seconds after the lane change
signal is turned off.)
. When the vehicle speed lowers to less

LANE CAMERA UNIT MAINTENANCE
The lane camera unit*1for the LDW/LDP
system is located above the inside mirror.
To keep the proper operation of the LDW/
LDP systems and prevent a system mal-
function, be sure to observe the following:
. 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) and Blind
Spot Intervention (BSI) systems can help
alert the driver of other vehicles in
adjacent lanes when changing lanes.
