– Illustration e: When the angle formed
by your vehicle and approaching ve-
hicle is small.
●The following conditions may reduce
the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice build up on the vehicle
– Frost build up on the vehicle
– Dirt up on the vehicle
●Do not attach stickers (including trans-
parent material) , install accessories or
apply additional paint near the radar
sensors. These conditions may reduce
the ability of the radar to detect other
vehicles.
●The sonar sensors detect stationary ob-
jects behind the vehicle. The sonar sen-
sor may not detect:
– Small or moving objects
– Wedge-shaped objects
– Object close to the bumper (less than
approximately 1 ft (30 cm))– Thin objects such as rope, wire and
chain, etc.
●The brake engagement by the BCI sys-
tem is not as effective on a slope as it is
on flat ground. When on a steep slope
the system may not function properly.
●Do not use the BCI system under the
following conditions because the sys-
tem may not function properly:
– When driving with a tire that is not
within normal tire conditions (e.g.
tire wear, low tire pressure, installa-
tion of spare tire, tire chains, non-
standard wheels) .
– When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
●Do not use the BCI systems when tow-
ing a trailer.
●Excessive noise (e.g. audio system vol-
ume, open vehicle window) will inter-
fere with the chime sound, and it may
not be heard.SYSTEM TEMPORARILY NOT
AVAILABLE
If the following messages appear on the vehicle
information display, a chime will sound and the
BCI system will be turned off automatically.
●“Unavailable High Accelerator Temp.”:
If the vehicle is parked in direct sunlight
under high temperature conditions (over ap-
proximately 104°F (40°C)) and then started,
the BCI system may be deactivated auto-
matically and the “Unavailable High Accel-
erator Temp” message will appear in the
vehicle information display for a period of
time.
When the interior temperature is reduced,
turn off the BCI system and turn it on again.
●“Unavailable Side Radar Obstruction”:
When side radar blockage is detected.
When the blockage is removed, turn off the
BCI system and turn it on again.

●As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive or
absentminded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween vehicles.
●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 and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
●Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance.
The ICC system may not be able to
maintain the selected distance between
vehicles (following distance) or se-
lected vehicle speed under some
circumstances.●The system may not detect the vehicle
in front of you in certain road or weather
conditions. To avoid accidents, never
use the ICC system under the following
conditions:
– On roads where the traffic is heavy or
there are sharp curves
– On slippery road surfaces such as on
ice or snow, etc.
– During bad weather (rain, fog, snow,
etc.)
– When rain, snow or dirt adhere to the
bumper around the distance sensor
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill
roads
– When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources.●Do not use the ICC system if you are
towing a trailer. The system may not
detect a vehicle ahead.
●In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the following
objects:
●Stationary and slow moving vehicles
●Pedestrians or objects in the roadway
●Oncoming vehicles in the same lane
●Motorcycles traveling offset in the travel lane
The following are some conditions in which the
sensor cannot properly detect a vehicle ahead
and the system may not operate properly:
●When snow or road spray from traveling
vehicles reduces the sensor’s detection.
●When excessively heavy baggage is loaded
in the rear seat or the cargo area of your
vehicle.

PREVIEW FUNCTION
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 20 mph
(32 km/h) 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.●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.
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. It is recom-
mended that you visit an INFINITI retailer
for this service.
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, it is recommended that you
visit 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.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious injury or death.
●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.The DCA system brakes and moves the accelera-
tor pedal upward according to the distance from
and the relative speed of the vehicle ahead to
help assist the driver to maintain a following dis-
tance.
DCA SYSTEM OPERATION
Always pay attention to the operation of the ve-
hicle and be ready to manually decelerate to
maintain the proper following distance. The DCA
system may not be able to decelerate the vehicle
under some circumstances.
The DCA system uses a sensor
Alocated be-
hind the front bumper of the vehicle to detect
vehicles traveling ahead. The sensor generally
detects the signals returned from the vehicle
ahead. Therefore, if the sensor cannot detect the
reflection from the vehicle ahead, the DCA sys-
tem may not operate.

DISTANCE CONTROL ASSIST (DCA)
(if so equipped)
Starting and driving5-95

The system is intended to assist the driver to
keep a following distance from the vehicle ahead
traveling in the same lane and direction.
The distance sensor is located behind the front
bumper
A. If the distance sensorAdetects a
slower moving vehicle ahead, the system will
reduce the vehicle speed to help assist the driver
to maintain a following distance.
The system automatically controls the throttle
and applies the brakes (up to 40% of vehicle
braking power) if necessary.
The detection range of the sensor is approxi-
mately 490 ft (150 m) ahead.
The distance sensor will not detect the following
objects.
●Stationary and slow moving vehicles
●Pedestrians or objects in the roadway
●Oncoming vehicles in the same laneThe display is located between the speedometer
and tachometer.
1. DCA system switch indicator:
Indicates that the dynamic driver assistance
switch is on.2. Vehicle ahead detection indicator:
Indicates whether it detects a vehicle in front
of you.
WARNING
The DCA system automatically deceler-
ates your vehicle to help assist the driver
to maintain a following distance from the
vehicle ahead. Manually brake when de-
celeration is required to maintain a safe
distance upon sudden braking by the ve-
hicle ahead or when a vehicle suddenly
appears in front of you. Always stay alert
when using the DCA system.

DCA SYSTEM LIMITATIONS
WARNING
●This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’s re-
sponsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
●This system will not adapt automatically
to road conditions.
●As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This system
does not correct careless, inattentive or
absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween vehicles.
●The system may not detect the vehicle
in front of you in certain road or weather
conditions. To avoid accidents, never
use the DCA system under the following
conditions:– On roads with sharp curves
– On slippery road surfaces such as on
ice or snow, etc.
– During bad weather (rain, fog, snow,
etc.)
– When rain, snow or dirt adhere to the
sensor area of the front bumper
– On steep downhill roads (frequent
braking may result in overheating the
brakes)
– On repeated uphill and downhill
roads
●Do not use the DCA system if you are
towing a trailer. The system may not
detect a vehicle ahead.
●In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You may
need to control the distance from other
vehicles using the accelerator pedal. Al-
ways stay alert and avoid using the DCA
system where not recommended in this
warning section.
Starting and driving5-99

The following are some conditions in which the
sensor cannot detect the signals:
●When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
●When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
detection
●When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the front
bumper area around the distance sensor is cov-
ered with dirt or is obstructed, the system will
automatically cancel. If the front bumper area of
the distance sensor is covered with ice, a trans-
parent or translucent vinyl bag, etc., the DCA
system may not detect them. In these instances,
the vehicle-to-vehicle distance control mode may
not cancel and may not be able to maintain the
selected following distance from the vehicle
ahead. Be sure to check and clean the front
bumper area around the distance sensor regu-
larly.The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as nec-
essary and if the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill. However,
the DCA system can only apply up to 40% of the
vehicle’s total braking power. If a vehicle moves
into the traveling lane ahead or if a vehicle travel-
ing ahead rapidly decelerates, the distance be-
tween vehicles may become closer because the
DCA system cannot decelerate the vehicle
quickly enough. If this occurs, the DCA system
will sound a warning chime and blink the system
display to notify the driver to take necessary
action.
For additional information, refer to “Approach
warning” in this section.
This system only brakes and moves the accelera-
tor pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.
The DCA system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead.
5-100Starting and driving

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the sensor may detect ve-
hicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may cause
the system to work inappropriately.
The detection of vehicles may also be affected by
vehicle operation (steering maneuver or traveling
position in the lane, etc.) or vehicle condition.If
this occurs, the system may warn you by
blinking the system indicator and sounding
the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.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 DCA system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance if:
●The chime sounds.
●The vehicle ahead detection indicator blinks.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 a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.

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. It is recommended that you visit an
INFINITI retailer for this service.
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.The VDC system uses various sensors to monitor
driver inputs and vehicle motion. Under certain
driving conditions, the VDC system helps to per-
form 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.
