The LDW and LDP systems monitor the lane
markers on the traveling lane using the
camera unit
*1located above the inside
mirror. When the camera unit detects that
the vehicle is traveling close to either the
left or the right of the traveling lane, the
driver assist system lane indicator (orange)
in the vehicle information display blinks
and a warning chime sounds. When the
LDP system is on, it will automatically
apply a steering operation for a short
period of time.
LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
. This system is only a warning device to
inform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or 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
the vehicle at all times.
. The system will not operate at speeds below approximately 45 MPH (70 km/h)
or if it cannot detect lane markers.
. If the LDW system malfunctions, it will
cancel automatically, and the LDW mal-
function message will appear in the
vehicle information display.
. If the LDW malfunction message ap-
pears, pull off the road to a safe location
and stop the vehicle. Turn the engine off
and restart the engine. If the LDW
malfunction message continues to ap-
pear, have the system checked by an
INFINITI retailer.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
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-stan-
dard lane markers; or lane markers
covered with water, dirt, snow, etc.
. On roads where the discontinued lane
markers are still detectable. .
On roads where there are sharp curves.
. On roads where there are sharply
contrasting objects, such as shadows,
snow, water, wheel ruts, seams or lines
remaining after road repairs. (The Lane
Departure Warning (LDW) 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.)

Driver assist system lane indicator
LDP system operation
The LDP system provides a lane departure
warning and steering 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
driver assist system lane indicator (orange)
will blink to alert the driver. Then, the LDP
system will automatically apply the steer-
ing for a short period of time to help assist
the driver to return the vehicle to the center
of the traveling lane.

5-42Starting and driving
.The radar sensors may not be able to
detect and activate BSI/BSW when
certain objects are present such as:
— Pedestrians, bicycles, animals
— Several types of vehicles such as
motorcycles
— Oncoming vehicles
— Vehicles remaining in the detection
zone when you accelerate from a
stop
— A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle
— A vehicle approaching rapidly from
behind.
— A vehicle which your vehicle over-
takes rapidly.
See also “BSW/BSI driving situations”
(P.5-43) for the situations in which the
radar sensors may not be able to detect
vehicle(s).
. Severe weather or road spray condi-
tions may reduce the ability of the
radar to detect other vehicles.
. The radar sensors’ detection zone is
designed based on a standard lane
width. When driving in a wider lane, the
radar sensors may not detect vehicles in an adjacent 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, how-
ever objects such as guardrails, walls,
foliage and parked vehicles may occa-
sionally be detected. This is a normal
operating condition.
. The camera may not detect lane mar-
kers in the following situations and the
BSI system may not operate properly.
— 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; lane mar-
kers 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 sha-
dows, snow, water, wheel ruts,
seams or lines remaining after road
repairs. —
On roads where the traveling lane
merges or separates.
— When the vehicle’s traveling direc-
tion does not align with the lane
markers.
— 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 a lane
camera unit.
— When the headlights are not bright
due to dirt on the lens or if aiming is
not adjusted properly.
— When strong light enters a lane
camera unit. (For example, light
directly shines on the front of the
vehicle at sunrise or sunset.)
— When a sudden change in bright-
ness occurs. (For example, when the
vehicle enters or exits a tunnel or
under a bridge.)

When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and
other lights are all operating properly and
installed securely. Also check headlight
aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires should be rotated
every 5,000 miles (8,000 km).
Tires*: Check the pressure with a gauge
often and always prior to long distance
trips. If necessary, adjust the pressure in
all tires, including the spare, to the
pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to
wear or age.
Tire, wheel alignment and balance: If thevehicle should pull to either side while
driving on a straight and level road, or if
you detect uneven or abnormal tire wear,
there may be a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to
“Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
Windshield: Clean the windshield on a
regular basis. Check the windshield at
least every six months for cracks or other
damage. Have a damaged windshield
repaired by a qualified repair facility.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism:
On a fairly steep hill, check that your
vehicle is held securely with the shift lever
in the P (Park) position without applying
any brakes.

operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.

HEADLIGHTS
If replacement is required, see an INFINITI
retailer.
Fog may temporarily form inside the lens of
the exterior lights in the rain or in a car
wash. A temperature difference between
the inside and the outside of the lens
causes the fog. This is not a malfunction. If
large drops of water collect inside the lens,
contact an INFINITI retailer.
