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.

5-36Starting and driving
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).

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.)

If the“AWD Error” warning*1appears,
there may be a malfunction in the Intelli-
gent AWD system. Reduce vehicle speed
and have your vehicle checked by an
INFINITI retailer as soon as possible.
The “AWD High Temp.” (high temperature)
warning
*2may appear while trying to free a stuck vehicle due to increased oil
temperature. The driving mode may change
to Two-Wheel Drive (2WD). If this warning
is displayed, stop the vehicle with the
engine idling, as soon as it is safe to do so.
Then if the warning turns off, you can
continue driving.
The
“Tire Size Incorrect” warning
*3may
appear if there is a large difference
between the diameters of front and rear
wheels. Pull off the road in a safe area,
with the engine idling. Check that all tire
sizes are the same, that the tire pressure is
correct and that the tires are not exces-
sively worn.
If any warning message continues to be
displayed, have your vehicle checked by an
INFINITI retailer as soon as possible.
WARNING
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.

.Wax your vehicle only after a thorough
washing. Follow the instructions sup-
plied with the wax.
. Do not use a wax containing any
abrasives, cutting compounds or clea-
ners that may damage the vehicle
finish.
Machine compound or aggressive polish-
ing on a base coat/clear coat paint finish
may dull the finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the paint surface to avoid lasting
damage or staining. Special cleaning
products are available at an INFINITI
retailer or any automotive accessory
stores.
UNDERBODY
In areas where road salt is used in winter,
the underbody must be cleaned regularly.
This will prevent dirt and salt from building
up and causing the acceleration of corro-
sion on the underbody and suspension.
Before the winter period and again in the
spring, the underseal must be checked
and, if necessary, re-treated.
GLASS
Use glass cleaner to remove smoke and
dust film from the glass surfaces. It is
normal for glass to become coated with a
film after the vehicle is parked in the hot
sun. Glass cleaner and a soft cloth will
easily remove this film.
CAUTION
When cleaning the inside of the windows,
do not use sharp-edged tools, abrasive
cleaners or chlorine-based disinfectant clea-
ners. They could damage the electrical
conductors, radio antenna elements or rear
window defroster elements.
WHEELS
Wash the wheels when washing the vehicle
to maintain their appearance.
. Clean the inner side of the wheels when
the wheel is changed or the underside
of the vehicle is washed.
. Inspect wheel rims regularly for dents
or corrosion. Such damage may cause
loss of pressure or poor seal at the tire
bead. .
INFINITI recommends that the road
wheels be waxed to protect against
road salt in areas where it is used
during winter.
CAUTION
Do not use abrasive cleaners when washing
the wheels.
Aluminum alloy wheels
Wash regularly with a sponge dampened in
a mild soap solution, especially during
winter months in areas where road salt is
used. Salt could discolor the wheels if not
removed.
CAUTION
Follow the directions below to avoid stain-
ing or discoloring the wheels:
. Do not use a cleaner that uses strong
acid or alkali contents to clean the
wheels.
. Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as

ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel:Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera- tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1.
Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil pan.
Exhaust system:
Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
