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.

System operation
WARNING
The Distance Control Assist system auto-
matically decelerates your vehicle to help
assist the driver to maintain a following
distance from the vehicle ahead. Manually
brake when deceleration is required to
maintain a safe distance upon sudden
braking by the vehicle ahead or when a
vehicle suddenly appears in front of you.
Always stay alert when using the DCA
system.
The DCA system helps assist the driver to keep a
following distance to the vehicle ahead by brak-
ing and moving the accelerator pedal upward in
the normal driving condition.
When a vehicle is detected ahead:
The vehicle ahead detection indicator comes on.
When vehicle approaches a vehicle ahead: ● If the driver’s foot is not on the accelerator
pedal, the system activates the brakes to
decelerate smoothly as necessary. If the ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill within the limita-
tions of the system. ●
If the driver’s foot is on the accelerator pedal,
the system moves the accelerator pedal up-
ward to assist the driver to release the ac-
celerator pedal.
When brake operation by driver is required:
The system alerts the driver by a warning chime
and blinking the vehicle ahead detection indica-
tor. If the driver’s foot is on the accelerator pedal
after the warning, the system moves the accel-
erator pedal upward to assist the driver to switch
to the brake pedal.
The stoplights of the vehicle come on when
braking is performed by the DCA system.
When the brake operates, a noise may be
heard. This is not a malfunction.
WARNING
● When the vehicle ahead detection indi-
cator light is not illuminated, the system
will not control or warn the driver.
● Depending on the position of the accel-
erator pedal, the system may not be
able to assist the driver to release the
accelerator pedal appropriately. ●
If the vehicle ahead comes to a stand-
still, the vehicle decelerates to a stand-
still within the limitations of the system.
The system will release brake control
with a warning chime once it judges the
vehicle is at a standstill. To prevent the
vehicle from moving, the driver must
depress the brake pedal. (The system
will resume control automatically once
the system reaches 3 MPH (5 km/h)) .
Overriding the system:
The following driver’s operations override the
system operation. ● When the driver depresses the accelerator
pedal even further while the system is mov-
ing the accelerator pedal upward, the DCA
system control of the accelerator pedal is
canceled.
● When the driver’s foot is on the accelerator
pedal, the brake control by the system is not
operated.
● When the driver’s foot is on the brake pedal,
neither the brake control nor the alert by the
system operates.
● When the ICC system is set, the DCA sys-
tem will be cancelled.

Action to take:
When the conditions listed above are no longer
present, turn the system off with the dynamic
driver assistance switch. Turn the DCA system
back on to use the system. Condition B:
When the sensor area of the front bumper is dirty,
making it impossible to detect a vehicle ahead,
the DCA system is automatically canceled.
The chime sounds and the system warning light
(orange) will come on and the “Sensor Blocked”
indicator will appear.
Action to take:
If the warning light comes on, park the vehicle in a
safe place, turn the engine off. Clean the sensor
area of the bumper and then perform the settings
again.
Condition C:
When the DCA system is not operating properly,
the chime sounds and the system warning light
(“DCA” 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 turn on the DCA system again.

tions, have the vehicle checked at an
INFINITI retailer.
Sensor maintenance
How to handle the sensor:
The sensor for the DCA system is common with
ICC and is located behind the front bumper.
For additional information, refer to “Intelligent
Cruise Control (ICC) system (Full speed range)”
in this section.The Forward Collision Warning (FCW) system
will warn the driver by a warning light and chime
when your vehicle is getting close to the vehicle
ahead in the traveling lane.
The FCW system will function when your vehicle
is driven at speeds of approximately 10 MPH
(15 km/h) and above.
The FCW system uses the distance sensor
A
located 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 travel lane, the vehicle ahead
detection indicator light on the instrument panel
blinks and a warning chime sounds.
The FCW system can be turned on/off by push-
ing the warning systems switch. The warning
systems ON indicator light

The Intelligent Brake Assist (IBA) system warns
the driver by a warning light and chime when
there is a risk of a collision with the vehicle ahead
in the traveling lane and the driver must take
avoidance action immediately. The system helps
reduce the rear-end collision speed by applying
the brakes when the system judges that the col-
lision cannot be prevented.
The IBA system will function when your vehicle is
driven at speeds of approximately 10 MPH
(15 km/h) and above, and when your vehicle is
driven at speeds approximately 10 MPH
(15 km/h) faster than the vehicle ahead.The IBA system uses a distance sensor
Alo-
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:

SYSTEM (if so equipped)
5-88Starting and driving
●The system is designed to automatically
check the sensor’s functionality. When
the sensor detects an obstruction of the
radar signals due to dirt, adhesive ma-
terial, or similar objects to the front
bumper, the system will automatically
cancel. However, sensor may not detect
all obstructive material. In these in-
stances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor area of the
front bumper regularly.
● Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
● A sudden appearance of a vehicle in
front (for example, it abruptly cuts in)
may not be detected and the system
may not warn the driver soon enough.
● The system will be cancelled automati-
cally with a beep sound and the IBA
warning light will illuminate under the
following conditions:
– When the sensor area of the front bumper is dirty
– When the system malfunctions If the IBA OFF indicator light illuminates with a
beep sound, pull off the road to a safe location,
stop the vehicle and turn the engine off. Check to
see if the sensor area of the front bumper is dirty.
If the sensor area of the front bumper is dirty,
clean it with a soft cloth and restart the engine. If
the sensor area of the front bumper is not dirty,
restart the engine. If the IBA OFF indicator light
continues to illuminate even if the IBA system is
turned on, have the system checked by an
INFINITI retailer.
IBA SYSTEM OPERATION
The IBA system will function when your vehicle is
driven at speeds of approximately 10 MPH
(15 km/h) or above, and when the vehicle’s
speed is approximately 10 MPH (15 km/h) faster
than that of the vehicle ahead.
To turn the system on/off:

system can be turned on or off. The IBA system will remain in the last ON or OFF
state it was left in until it is changed in the vehicle
information display. For additional information,
refer to “Driver Assistance” in the “Instrument and
controls” section of this manual.
Illumination of the IBA OFF indicator light without
the warning chime sound is an indication that the
IBA system is temporarily unavailable. It will occur
under the following conditions:
When the radar signal is temporarily interrupted.
The IBA OFF indicator light will turn off when the
system returns to its normal operating conditions.

5-90Starting 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.
