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 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.
● 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.
● On roads where there are sharp curves.

5-22Starting and driving

The brightness of the BSW indicator lights is
adjusted automatically depending on the
brightness of the ambient light.
A chime sounds if the radar sensors have
already detected vehicles when the driver acti-
vates the turn signal. If a vehicle comes into the
detection zone after the driver activates the turn
signal, then only the BSW indicator light flashes
and no chime sounds. (See “BSW DRIVING
SITUATIONS” later in this section)
The BSW system is automatically turned on
when the engine is started and the warning
systems ON indicator light
1illuminates on
the switch. You can turn the BSW system off by
pushing the warning systems switch on the
instrumental panel. This switch will turn on and
off the LDW, BSW and FCW systems at the same
time.
NOTE:
If you continue to push the warning systems
switch from off to on for over 4 seconds, a chime
will sound. This will change the default status of
the LDW, BSW and FCW systems to OFF so that
these systems will not automatically turn on
when the engine is started. If this procedure is
repeated, the default status will return to ON.
WARNING
● Do not use the BSW system when towing a
trailer because the system may not function
properly.
● Excessive noise (e.g. audio system volume,
open vehicle window) will interfere with the
chime sound, and it may not be heard.
● The radar sensors may not be able to detect
and activate BSW when certain objects are
present such as:
– Pedestrians, bicycles, animals
– Several types of vehicles such as motor- cycles
– Oncoming vehicles
– Vehicles remaining in the detection zone when you accelerate from a stop
(See “BSW DRIVING SITUATIONS” later in
this section)
– A vehicle merging into an adjacent lane at a speed approximately the same as your
vehicle
(See “BSW DRIVING SITUATIONS” later in
this section) – A vehicle approaching rapidly from be-
hind.
(See “BSW DRIVING SITUATIONS” later in
this section)
– A vehicle which your vehicle overtakes rapidly.
(See “BSW DRIVING SITUATIONS” later in
this section)
● Severe weather or road spray conditions
may reduce the ability of the radar to detect
other vehicles.
● The radar sensors detection zone is de-
signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an adja-
cent lane. When driving in a narrow lane, the
radar sensors may detect vehicles driving
two lanes away.
● The radar sensors are designed to ignore
most stationary objects, however objects
such as guardrails, walls, foliage and parked
vehicles may occasionally be detected. This
is a normal operating condition.
Starting and driving5-27

If the driver activates the turn signal, then the
BSW indicator light flashes and a chime will
sound twice.
NOTE:
If the driver activates the turn signal before a
vehicle enters the detection zone, the BSW indi-
cator light will flash but no chime will sound
when another vehicle is detected.
BSW temporarily not available
●When radar blockage is detected, the BSW
system will be turned off automatically, a
beep will sound and the BSW system warn- ing light (orange) will blink. The BSW system
is not available until the condition no longer
exists.
The radar sensors may be blocked by temporary
ambient conditions such as splashing water,
mist or fog. The blocked condition may also be
caused by objects such as ice, frost or dirt
obstructing the radar sensors.
Action to take:
When the above condition no longer exists, the
BSW system will resume automatically.
If the warning light (orange) continues to blink,
have the BSW system checked by an INFINITI
retailer.
BSW MALFUNCTION
When the BSW system malfunctions, they will
be turned off automatically, a beep will sound
and the BSW system warning light (orange) will
illuminate.
Action to take:
Stop the vehicle in a safe location, turn the
engine off and restart the engine.
If the warning light (orange) continues to illu-
minate, have the BSW system checked by an
INFINITI retailer.
SYSTEM MAINTENANCE
The two radar sensor unitsAfor the BSW
system are located near the rear bumper. Al-
ways keep the area near the radar sensors
clean. Do not attach stickers (including trans-
parent material), install accessories or apply
additional paint near the radar sensors. Do not
strike or damage the area around the radar
sensors. Consult an INFINITI retailer if the area
around the radar sensors is damaged due to a
collision.

5-42Starting and driving

●The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the
distance. ●
If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that vehicle
or if another vehicle cuts in, the system warns
the driver with the chime and ICC system dis-
play. Decelerate by depressing the brake pedal
to maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection and set dis-
tance indicator blink.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are:
● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
● When the accelerator pedal is depressed,
overriding the system
● When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.
