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 trav-
eling 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 con-
ditions of road, lane marker or weather,
or when you change lanes without us-
ing 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 accidents. ●
When the LDP system is operating,
avoid excessive or sudden steering ma-
neuvers. Otherwise, you could lose con-
trol 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.
● 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, etc.
– 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.

RADAR MAINTENANCE
The two radar sensors1for the BSW, BSI and
BCI systems are located near the rear bumper.
Always keep the area near the radar sensors
clean.
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. Check for and remove objects obstructing the
area around the radar sensors.
Do not attach stickers (including transparent ma-
terial) , 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.

Warning light
When the system is not operating properly, the
chime sounds and the system warning light (or-
ange) will come on.
Action to take:
If the warning light comes on, park the vehicle in a
safe place. Turn the engine off, restart the engine,
resume driving and then perform the setting
again.If it is not possible to set or the indicator
stays on, it may indicate that the system is
malfunctioning. Although the vehicle is still
driveable under normal conditions, have
the vehicle checked at an INFINITI retailer.
PREVIEW FUNCTION (for ICC
system equipped models)
The ICC system with the Preview Function iden-
tifies the need to apply emergency braking by
sensing the vehicle ahead in the same lane and
the distance to the vehicle ahead and relative
speed from it. It applies the brake pre-pressure
before the driver depresses the brake pedal and
helps improve brake response by reducing pedal
free play.
For additional information, refer to “Brake assist”
in this section.
The (DCA) system brakes and moves the accel-
erator pedal upward according to the distance
from and the relative speed of the vehicle ahead
to help assist the driver to maintain a following
distance.
WARNING
●
DCA helps maintain a distance to the
vehicle in front under certain condi-
tions. It is not a collision avoidance sys-
tem. Failure to apply the brakes could
result in an accident.
● Always drive carefully and attentively
when using the DCA system. Read and
understand the Owner’s Manual thor-
oughly before using the DCA system.
Do not use the DCA system except in
appropriate road and traffic conditions.
● If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill
within the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill with
a warning chime. To prevent the vehicle
from moving, the driver must depress
the brake pedal.
● The DCA system will not apply brake
control while the driver’s foot is on the
accelerator pedal.
LSD2067
DISTANCE CONTROL ASSIST (DCA)
SYSTEM (if so equipped)
5-72Starting and driving

The IBA system uses a distance sensorAlo-
cated behind the front bumper to measure the
distance to the vehicle ahead. When the system
judges that your vehicle is getting close to the
vehicle ahead in the traveling lane, the vehicle
ahead detection indicator light on the information
display blinks and a warning chime sounds.
The IBA system can be turned on/off by in the
settings of the vehicle information display. For
additional information, refer to “Driving aids” in
the “Instrument and controls” section of this
manual.PRECAUTIONS ON IBA SYSTEM
WARNING
● The IBA system is not a collision avoid-
ance system. It is the driver’s responsi-
bility to stay alert, drive safely and be in
control of the vehicle at all times.
● As there is a performance limit, the sys-
tem may not provide a warning or brak-
ing in certain conditions.
● The system will not detect the following
objects:
– Pedestrians, animals or obstacles in the roadway – Oncoming vehicles in the same lane
● The sensor generally detects the sig-
nals returned from the vehicle ahead.
Therefore, the system may not function
properly under the following
conditions:
– When the sensor area of the front bumper gets dirty and it is impos-
sible to detect the distance from the
vehicle ahead.
– When radar signal is temporarily interrupted.
– When visibility is low (such as rain, fog, snow, etc.) .
– When snow or road spray from trav- eling vehicles is splashed.
– When excessively heavy baggage is loaded in the rear seat or the luggage
room of your vehicle.
– When abruptly accelerating or decelerating.
– On a steep downhill slope or on roads with sharp curves.

5-86Starting and driving

WARNING
●If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
● When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle but the steering will be
harder to operate. Have the power
steering system checked by an INFINITI
retailer.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. If the steering wheel operation is still per-
formed, the power steering may stop and the
power steering warning light will illuminate. In a
safe location, stop the engine and push the igni-
tion switch to the OFF position. The temperature of the power steering system will go down after a
period of time and the power assist level will
return to normal after starting the engine. The
power steering warning light will go off. Avoid
repeating such steering wheel operations that
could cause the power steering system to over-
heat.
You may hear a sound from the front of the vehicle
when the steering wheel is operated quickly. This
is a normal operational noise and is not a mal-
function.
If the electric power steering warning light
PS
illuminates while the engine is running, it may
indicate the power steering system is not func-
tioning properly and may need servicing. Have
the power steering system checked by an
INFINITI retailer.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information, refer to “Power steer-
ing warning light” in the “Instruments and con-
trols” section of this manual. The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
POWER STEERING
BRAKE SYSTEM
5-94Starting and driving

WARNING
●While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
● If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break-in the parking brake shoes whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or rotors are
replaced, in order to assure the best brake per-
formance. This procedure is described in the INFINITI Ser-
vice Manual and can be performed by an INFINITI
retailer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●
The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front of
you. Ultimately, the driver is respon-
sible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, refer to “Tire and loading
information label” in the “Technical
and consumer information” section
of this manual.
– For additional information, refer to “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
Starting and driving5-95

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h). The speed varies according to road
conditions.When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. it is the driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
PREVIEW FUNCTION (Intelligent
Cruise Control system equipped
models)
When the Preview Function identifies the need to
apply emergency braking by sensing a vehicle
ahead in the same lane and the distance and
relative speed from it, it applies the brake pre-
pressure before the driver depresses the brake
pedal and helps improve brake response by re-
ducing pedal free play.
● This system will not operate when the ve-
hicle is moving at approximately 32 km/h
(20 MPH) or less.
● The pre-pressure function ceases when the
following conditions are met:
1. When the driver depresses the accelerator pedal or the brake pedal.
2. If the driver does not operate the accelerator or brake pedal within approximately 1 sec-
ond.
5-96Starting and driving

●The sensor will not detect:
1. Pedestrians or objects in the roadway
2. Oncoming vehicles in the same lane
3. Motorcycles traveling offset in the travel lane as illustrated
WARNING
●This system is only an aid to assist brak-
ing operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times. ●
As there is a performance limit to the
Preview Function, never rely solely on
this system. This system does not cor-
rect careless inattentive or absent-
minded driving, or overcome poor vis-
ibility in rain, fog, or other bad weather.
Reduce vehicle speed by depressing the
brake pedal, in order to maintain a safe
distance between vehicles.
● The system may not detect the vehicle
in front of you in certain road or weather
conditions. The Preview Function may
not operate properly under the follow-
ing conditions. The vehicle is still drive-
able under normal conditions and the
Brake Assist will operate.
– When rain, snow or dirt adhere to the system sensor
– When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle
– Winding or hilly roads may cause the sensor to temporarily not detect a
vehicle in the same lane or may de-
tect objects or vehicles in other
lanes. – Vehicle position in the lane may
cause the sensor to temporarily not
detect a vehicle in the same lane or
may detect objects or vehicles in
other lanes.

Starting and driving5-97

Warning light and display
When the Preview Function is not operating
properly, the chime sounds and the system warn-
ing light (orange) will come on.
Action to take:
If the warning light comes on, park the vehicle in a
safe place. Turn the engine off, restart the engine
and resume driving.
If the indicator stays on, it may indicate that
the Preview Function is malfunctioning
(the brake is operative) . Although the ve-
hicle is still driveable under normal condi-tions, have the vehicle checked at an
INFINITI retailer.
How to handle the sensor
The sensor for the Preview Function is common
with the ICC and is located below the front
bumper.
To keep the Preview Function operating properly,
be sure to observe the following:
● Always keep the area around the sensor
clean.
● Do not strike or damage the areas around
the sensor.
● Do not touch or remove the screw located
on the sensor. Doing so could cause failure
or malfunction. If the sensor is damaged due
to an accident, contact an INFINITI retailer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion. The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving conditions,
the VDC System helps to perform the following
functions:
● Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.
When the VDC system operates, the
indi-
cator in the instrument panel flashes to note the
following:
LSD2067
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-98Starting and driving

●The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
● You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
● Adjust your speed and driving to the road
conditions.
For additional information, refer to “Slip indicator
light” and ”Vehicle Dynamic Control (VDC) OFF
indicator light” in the ”Instruments and controls”
section of this manual.
If a malfunction occurs in the system, the
andindicator lights come on in the instru-
ment panel. The VDC system automatically turns
off when these indicator lights are on.
The VDC OFF switch is used to turn off the VDC
system. The
indicator illuminates to indi-
cate the VDC system is off.
When the VDC switch is used to turn off the
system, the VDC system still operates to prevent
one drive wheel from slipping by transferring
power to a non slipping drive wheel. The
indicator flashes if this occurs. All other VDC
functions are off and the
indicator will not
flash. The VDC system is automatically reset to on
when the ignition switch is placed in the OFF
position then back to the ON position.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in reverse
at a slow speed. When the self-test occurs, you
may hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
●
The VDC system is designed to help the
driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving tech-
niques. Reduce vehicle speed and be
especially careful when driving and cor-
nering on slippery surfaces and always
drive carefully. ●
Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the
indicator may
flash or both the
andindica-
tor lights may illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extremely
deteriorated, the VDC system may not
operate properly and both the
and theindicator lights may
illuminate.
● If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate.
