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 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 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.

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.

PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the distance sensor
*Adetects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance.
The system automatically controls the
throttle and applies the brakes (up to
25% of vehicle braking power) if neces- sary.
The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING
.
This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the
system in city traffic or congested areas.
. This system will not adapt automatically
to road conditions. This system should
be used in evenly flowing traffic. Do not
use the system on roads with sharp
curves, or on icy roads, in heavy rain or
in fog.
The distance sensor will not detect the
following objects:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway .
Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not detect the vehicle in
front of you in certain road or weather

PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
The ICC system with the preview function
identifies the need to apply emergency
braking by sensing the vehicle ahead in
the same lane and the distance to the
vehicle ahead and relative speed from it, it
applies the brake pre-pressure before the
driver depresses the brake pedal and helps
improve brake response by reducing pedal
free play.
For more details, see“Brake assist”(P.5-
81). The Distance Control Assist (DCA) system
brakes and moves the accelerator pedal
upward according to the distance from and
the relative speed of the vehicle ahead to
help assist the driver to maintain a
following distance.
WARNING
.
Always drive carefully and attentively
when using the Distance Control Assist
system. Read and understand the Own-
er’s Manual thoroughly before using the
DCA system. To avoid serious injury or
death, do not rely on the system to
prevent accidents or to control the
vehicle’s speed in emergency situations.
Do not use the Distance Control Assist
system except in appropriate road and
traffic conditions.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill with
a warning chime. To prevent the vehicle
from moving, the driver must depress
the brake pedal. .
The DCA system will not apply brake
control while the driver’s foot is on the
accelerator pedal.

the Distance Control Assist system
under the following conditions:
—On roads with sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—During bad weather (rain, fog, snow,etc.)
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle

In these instances, the Distance Control
Assist (DCA) system may not be able to
decelerate the vehicle properly. Be sure to
check and clean the sensor regularly.
The DCA system is designed to help assist
the driver to maintain a following distance
from the vehicle ahead. The system will
decelerate as necessary and if the vehicle
ahead comes to a stop, the vehicle
decelerates to a standstill. However, the
DCA system can only apply up to 25% of
the vehicles total braking power. If a
vehicle moves into the traveling lane ahead
or if a vehicle traveling ahead rapidly
decelerates, the distance between vehicles
may become closer because the DCA
system cannot decelerate the vehicle
quickly enough. If this occurs, the DCA
system will sound a warning chime and
blink the system display to notify the driver
to take necessary action.
See“Approach warning” (P.5-46).
This system only brakes and moves the
accelerator pedal upward to help assist the
driver to maintain a following distance
from the vehicle ahead. Acceleration
should be operated by the driver.
The DCA system does not control vehicle
speed or warn you when you approach stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead.
