LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDP system. Failure to follow the
warnings and instructions for proper use of
the LDP system could result in serious in-
jury or death.
• The LDP system may activate if you
change lanes without first activating
your turn signal or, for example, if a con-
struction zone directs traffic to cross an
existing lane marker. If this occurs you
may need to apply corrective steering to
complete your lane change.
• Because the LDP may not activate under
the road, weather, and lane marker con-
ditions described in this section, it may
not activate every time your vehicle be-
gins to leave its lane and you will need to
apply corrective steering.
• The LDP system will not operate at
speeds below approximately 37 mph (60
km/h) or if it cannot detect lane markers.
• When the LDP system is operating,
avoid excessive or sudden steering ma-
neuvers. Otherwise, you could lose con-
trol of the vehicle. •
Do not use the LDP system under the
following conditions as it may not func-
tion properly:
– During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such
as on ice or snow.
– When driving on winding or uneven
roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshift or tem-
porary lane.
– When driving on roads where the lane
width is too narrow.
– When driving without normal tire
conditions (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 suspen-
sion parts.
• 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-
standard lane markers; or lane mark-
ers 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 shad-
ows, 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 direc- tion 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.
5-42Starting and driving

– When strong light enters the lanecamera unit. (For example, the light
directly shines on the front of the ve-
hicle at sunrise or sunset.)
– When a sudden change in brightness occurs. (For example, when the ve-
hicle 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 nor-
mal and indicates that the LDP system is
operating properly.
SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the LDP
system are not designed to work under the
following conditions:
• When you operate the lane change signal and change the traveling lanes in the direc-
tion of the signal. (The LDP system will be
deactivated for approximately 2 seconds
after the lane change signal is turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h). After the above conditions have finished and
the necessary operating conditions are satis-
fied, the warning and assist functions will
resume.
Condition B:
The assist function of the LDP system is not
designed to work under the following condi-
tions (warning is still functional):
• When the brake pedal is depressed.
• When the steering wheel is turned as far as
necessary for the vehicle to change lanes.
• When the vehicle is accelerated during LDP system operation.
• When the Intelligent Cruise Control (ICC) approach warning occurs.
• When the hazard warning flashers are operated.
• When driving on a curve at high speed.
After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDP system application of the
brakes will resume. Condition C:
If the following messages appear in the ve-
hicle information display the LDP system will
be turned off automatically:
• “Not Available Poor Road Conditions”:
When the VDC system (except Traction
Control System [TCS] function) or ABS
operates.
• “Currently not available”: When the VDC system is turned off.

2. BSW indicator3. BSI ON indicator
4. ProPILOT Assist switchThe BSI system operates above approxi-
mately 37mph (60 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light (1)
illuminates. If the turn signal is then activated,
the system chimes (twice) and the side indi-
cator light flashes. The side indicator light
continues to flash until the detected vehicle
leaves the detection zone.
If the BSI system is on and your vehicle ap-
proaches a lane marker while another vehicle
is in the detection zone, the system chimes
(three times) and the side indicator light
flashes. The BSI system activates to help re-
turn the vehicle back to the center of the
driving lane. The BSI system operates regard-
less of turn signal usage.
NOTE:
•
BSI warning and system application will
only be activated if the side indicator light
is already illuminated when your vehicle
approaches a lane marker. If another ve-
hicle comes into the detection zone after
your vehicle has crossed a lane marker, no
BSI warning or system application will be
activated. For additional information, see
“BSI driving situations” (P. 5-59 ).

SYSTEM MAINTENANCE
The lane camera unitO1for the BSI system is
located above the inside mirror. The two ra-
dar sensors
O2for the BSI system are located
near the rear bumper. To keep the proper
operation of the BSI system and prevent a
system malfunction, be sure to observe the
following:
• Always keep the windshield and the area near the radar sensors clean. • The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the radar sen-
sors. Check for and remove objects ob-
structing the area around the radar
sensors.
• Do not attach stickers (including transpar- ent material), install accessories or apply
additional paint near the camera unit or
radar sensors.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
• Do not strike or damage the area around the radar sensors. Do not touch the camera
lens or remove the screw located on the
camera unit. It is recommended that you
visit an INFINITI retailer if the camera unit
and/or area around the radar sensors is
damaged due to a collision.

ICC system operation
The ICC system is designed to maintain a
selected distance from the vehicle in front of
you and can reduce the speed to match a
slower vehicle ahead. The system decelerates
the vehicle as necessary and if the vehicle
ahead comes to a stop, the vehicle deceler-
ates to a standstill. However, the ICC system
can only apply up to 40% of the vehicle’s total
braking power. This system should only be
used when traffic conditions allow vehicle
speeds to remain fairly constant or when ve-
hicle speeds change gradually. 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 ICC system cannot decel-
erate the vehicle quickly enough. If this oc-
curs, the ICC system sounds a warning chime
and blinks the system display to notify the
driver to take necessary action.
The ICC system cancels and a warning chime
sounds if the speed is below approximately
15 mph (25 km/h) and a vehicle is not de-
tected ahead.The ICC system operates as follows:
• When there are no vehicles traveling ahead,
the ICC system maintains the speed set by
the driver. The set speed range is between
approximately 20 and 90 mph (30 and 144
km/h).
• When there is a vehicle traveling ahead, the ICC system adjusts the speed to maintain
the distance, selected by the driver, from
the vehicle ahead. If the vehicle ahead
comes to a stop, the vehicle decelerates to
a standstill. Once your vehicle stops, the
ICC system keeps the vehicle stopped.
• When your vehicle is stopped for less than 3 seconds and the vehicle ahead begins to
move, your vehicle will start moving again
automatically.
• When your vehicle is at a standstill for more than 3 seconds and the vehicle ahead be-
gins to accelerate, push the RES+ switch or
lightly depress the accelerator pedal. The
ICC system starts to follow the vehicle
ahead.
• When the vehicle traveling ahead moves to a different traveling lane, the ICC system
accelerates and maintains vehicle speed up
to the set speed. The ICC system does not control vehicle
speed or warn you when you approach sta-
tionary and slow moving vehicles. You must
pay attention to vehicle operation to main-
tain proper distance from vehicles ahead
when approaching toll gates or traffic
congestion.
