LANE DEPARTURE PREVENTION
(LDP) SYSTEM
Precautions on LDP system
WARNING
.The LDP system will not always steer the
vehicle to keep it in the lane. It is not
designed to 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
vehicle at all times.
. The LDP system is primarily intended for
use on well-developed freeways or high-
ways. It may not detect the lane markers
in certain roads, weather or driving
conditions.
. Using the LDP system under some
conditions of road, lane marker or
weather, or when you change lanes
without using the lane change signal
could lead to an unexpected system
operation. In such conditions, you need
to correct the vehicle’s direction with
your steering operation to avoid acci-
dents. .
When the LDP system is operating, avoid
excessive or sudden steering maneu-
vers. 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 thelane width is too narrow.
—When driving with a tire that is notwithin 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 steering parts or sus-
pension parts.
. If the LDP system malfunctions, it will
cancel automatically. The LDP “malfunc-
tion” message will appear in the vehicle
information display.
. If the “malfunction” message appears,
pull off the road to a safe location and
stop the vehicle. Turn the engine off and
restart the engine. If the “malfunction”
message continues to appear, 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 steering 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; lane markers cov-

Automatic deactivation
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 direction of the signal. (The LDP
system will be deactivated for approxi-
mately 2 seconds after the lane change
signal is turned off.)
. When the vehicle speed lowers to less
than approximately 45 MPH (70 km/h).
. When the BSI system activates an
audible warning or steering control.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the warning and assist functions
will resume.
Condition B:
The assist function of the LDP system is not
designed to work under the following
conditions (warning is still functional):
. When the steering wheel is turned as
far as necessary for the vehicle to
change lanes. .
When the accelerator pedal is de-
pressed while the steering control
assist is provided.
. 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
satisfied, the LDP steering control assist
function will resume.
Condition C:
Under the following conditions, a beep will
sound and the LDP system will be canceled
automatically. The “LDP currently unavail-
able” message will appear in the vehicle
information display, and the LDP system
cannot be activated:
. When the VDC system (except TCS
function) or ABS operates.
. When the VDC system is turned off.
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode.
Action to take:
When the above conditions no longer exist,
push the dynamic driver assistance switch
again to turn the LDP system back on. Temporary disabled status at high tem-
perature:
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 1048F (408C)) and then the
LDP system is turned on, the LDP system
may be deactivated automatically. The
“ high cabin temperature” message will
appear in the vehicle information display.
Action to take:
When the above conditions no longer exist,
push the dynamic driver assistance switch
again to turn the LDP system back on.
LANE CAMERA UNIT MAINTENANCE
The LDW/LDP system uses the same lane
camera unit that is used by Active Lane
Control, located above the inside mirror.
For maintenance of the camera, see “Lane
camera unit maintenance ”(P.5-29).

Side indicator light
The BSW system operates above approxi-
mately 20 MPH (32 km/h). If the radar
sensors detect vehicles in the detection
zone, the side indicator light illuminates. If
the driver then activates the turn signal, a
chime will sound twice and the side
indicator light will flash.
The BSI system operates above approxi-
mately 37 MPH (60 km/h). If the system
detects a vehicle in the detection zone and
your vehicle is approaching the lane
marker, the BSI system provides an audi-
ble warning (three times), flashes the side
indicator light and slightly applies the
steering for a short period of time to help return the vehicle back to the traveling
lane. The BSI system provides an audible
warning and turns on or flashes the side
indicator light even if the BSW system is
off.
WARNING
.
The BSW and BSI systems are not a
replacement for proper driving procedure
and are not designed to prevent contact
with vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the direc-
tion you will move to ensure it is safe to
change lanes. Never rely solely on the
BSW or BSI system.
. Using the BSI system under some road,
lane marker or weather conditions could
lead to improper system operation. Al-
ways rely on your own steering and
braking operation to avoid accidents.
. The BSW and BSI systems may not
provide a warning or steering control
for vehicles that pass through the
detection zone quickly.

Side indicator light
BSW system operation
If the radar sensors detect vehicles in the
detection zone, the side indicator light
located inside the vehicle (near the outside
mirrors) illuminates. If the turn signal is
then activated, the side indicator light
flashes and a chime sounds twice. The
side indicator light continues to flash until
the detected vehicles leave the detection
zone.
The side indicator lights illuminate for a
few seconds when the ignition switch is
placed in the ON position.

The brightness of the side 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
activates the turn signal. If a vehicle comes
into the detection zone after the driver
activates the turn signal, then only the side
indicator light flashes and no chime
sounds. (See“BSW/BSI driving situations”
(P.5-43).)

Side indicator light
BSI system operation
If the radar sensors detect vehicles in the
detection zone, the side indicator light
located inside the vehicle (near the outside
mirrors) illuminates. If your vehicle is
approaching a lane marker, the side
indicator light flashes and an audible
warning will sound three times. Then the
system applies the steering for a short
period of time to help return the vehicle
back to the center of the lane. BSI operates
regardless of turn signal usage.NOTE:
.
Warning and steering control will only
be activated if the side indicator light
is already illuminated when your vehi-
cle approaches a lane marker. If
another vehicle comes into the detec-
tion zone after your vehicle has
crossed a lane marker, no warning or
steering control will be activated. (See
“BSW/BSI driving situations” (P.5-43).)
. The BSI system is typically activated
earlier than the Lane Departure Pre-
vention (LDP) system when your vehi-
cle is approaching a lane marker.
