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 re-
sponsibility 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 highways. It
may not detect the lane markers in certain
roads, weather or driving conditions.
● Using the LDP system under some condi-
tions of road, lane marker or weather, or
when you change lanes without using the
lane change signal could lead to an unex-
pected system operation. In such condi-
tions, you need to correct the vehicle’s direc-
tion with your steering operation to avoid
accidents.
● When the LDP system is operating, avoid
excessive or sudden steering maneuvers.
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 to road repairs.
– When driving in a makeshift lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire condi- tions (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 suspension parts.
– When towing a trailer or other vehicle. ●
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 loca-
tion 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 warn-
ing 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 conditions:
● On roads where there are multiple 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.
5-24Starting and driving

●On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing 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 warn-
ing and brake control assistance 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. Then, the LDP system will automatically
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.

SELECTING VEHICLE-TO-VEHICLE
DISTANCE CONTROL MODE
To choose the vehicle-to-vehicle distance con-
trol mode
1, quickly push and release the
MAIN switch
A.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control mode,
the Intelligent Cruise Control (ICC) system auto-
matically maintains a selected distance from
the vehicle traveling in front of you according to
that vehicle’s speed (up to the set speed), or at
the set speed when the road ahead is clear.
With ICC, the driver can maintain the same
speed as other vehicles without the constant
need to adjust the set speed as you would with
a normal cruise control system.
PRECAUTIONS ON VEHICLE-TO-
VEHICLE DISTANCE CONTROL MODE
The system is intended to enhance the opera-
tion 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 necessary.
The detection range of the sensor is approxi-
mately 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 sys-
tem on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
The distance sensor will not detect the follow-
ing 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

PREVIEW FUNCTION (for Intelligent
Cruise Control (ICC) system equipped
model)
The Intelligent Cruise Control (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 “INTELLIGENT CRUISE
CONTROL (ICC) SYSTEM” earlier in this section.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 Owner’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 sys-
tem 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.
