2012 INFINITI FX warning light

The Lane Departure Warning (LDW) sys-
tem/Lane Departure Prevention (LDP) sys-
tem will operate when the vehicle is driven
at speeds of approximately 45 MPH (70
km/h) and above, and when it is traveling
close to either the left or the right of a
traveling lane.
Each system functions as follows:
.Lane Departure Warning (LDW) system
— warns the driver with a warning light
and chime that the vehicle is beginning
to leave the driving lane.
. Lane Departure Prevention (LDP) system
— warns the driver with a warning light
and chime, and helps assist the driver
to return the vehicle to the center
direction of the traveling lane by
applying brake control to the left or
right wheels individually (for a short
period of time).

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 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 warningsystems ON indicator
*1on the warning
systems switch illuminates. To cancel the
LDW system, push the warning systems
switch. The warning systems ON indicator
will turn off. To turn on the system, push
the warning systems switch again.
When the warning systems switch is
pushed, the FCW system will also turn on
or off simultaneously. See“ FCW system
operation” (P.5-70)
In the manual setting mode, you need to
push the warning systems switch to turn
on the system after the ignition switch is
pushed to the ON position.
The setting mode can be changed using
the warning systems switch. To change the
setting mode, push and hold the warning
systems switch for more than 4 seconds
when the warning systems ON indicator is
off. When the mode is changed, a chime
sounds and the lane departure warning
light (orange) flashes.

(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 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 withnonoriginal brake parts or suspen-
sion parts.
—When you are towing a trailer.
. 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.
