The Lane Departure Warning (LDW)
system/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 by a warning light and
chime.
● Lane Departure Prevention (LDP) system —
warns the driver by 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). The LDW and LDP systems monitor the lane
markers on the traveling lane using the camera
unit
1located inside the front map light cover.
When the camera unit detects that the vehicle is
traveling close to either the left or the right of
the traveling lane, the lane departure warning
light on the instrument panel blinks in orange
and a warning chime sounds. When the LDP
system is on, it will automatically apply the
brakes for a short period of time, using the
function of the Vehicle Dynamic Control (VDC)
system.
LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
● This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It 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 the vehicle at all times.
● The system will not operate at speeds below
approximately 45 MPH (70 km/h) or if it can-
not detect lane markers.

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.

●The cruise control will automatically cancel if
the vehicle slows more than 7 MPH (12 km/h)
below the set speed.
● If you move the selector lever to N (Neutral)
position, the cruise control will be canceled.
To reset at a faster cruising speed, use one of
the following methods:
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the SET/COAST switch.
● Push and hold the RESUME/ACCELERATE
switch. When the vehicle attains the speed
you desire, release the switch.
● Push, then quickly release the
RESUME/ACCELERATE switch. Each time you
do this, the set speed will increase by about
1 MPH (1.6 km/h). To reset at a slower cruising speed,
use one of
the following methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
SET/COAST switch and release it.
● Push and hold the SET/COAST switch. Re-
lease the switch when the vehicle slows
down to the desired speed.
● Push, then quickly release the SET/COAST
switch. Each time you do this, the set speed
will decrease by about 1 MPH (1.6 km/h).
To resume the preset speed, push and release
the RESUME/ACCELERATE switch. The vehicle
will resume the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h). The Intelligent Cruise Control (ICC) system au-
tomatically 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.
The ICC function can be set to one of two cruise
control modes:
●
Vehicle-to-vehicle distance control mode:
For maintaining a selected distance between
your vehicle and the vehicle in front of you
up to the preset speed.
● Conventional (fixed speed) cruise control
mode:
For cruising at a preset speed.
WARNING
● Always drive carefully and attentively when
using either cruise control mode. Read and
understand the Owner’s Manual thoroughly
before using the ICC system. To avoid seri-
ous injury or death, do not rely on the system
to prevent accidents or to control the vehi-
cle’s speed in emergency situations. Do not
use the ICC system except in appropriate
road and traffic conditions.

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
