System operation
WARNING
Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle
ahead. Depress the accelerator to prop-
erly accelerate your vehicle when accel-
eration is required for a lane change. De-
press the brake pedal when deceleration
is required to maintain a safe distance to
the vehicle ahead due to its sudden brak-
ing or if a vehicle cuts in. Always stay alert
when using the ICC system.
The driver sets the desired vehicle speed based
on the road conditions. The ICC system main-
tains the set vehicle speed, similar to standard
cruise control, as long as no vehicle is detected in
the lane ahead.
The ICC system displays the set speed.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead, the
ICC system decelerates the vehicle by control-
ling the throttle and applying the brakes to match
the speed of a slower vehicle ahead. The system then controls the vehicle speed based on the
speed of the vehicle ahead to maintain the driver
selected distance.
The stoplights of the vehicle come on when
braking is performed by the ICC system.
When the brake operates, a noise may be
heard. This is not a malfunction.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and se-
lected distance.
Vehicle ahead not detected:
When a vehicle is no longer detected ahead, the
ICC system gradually accelerates your vehicle to
resume the previously set vehicle speed. The ICC
system then maintains the set speed.
When a vehicle is no longer detected the vehicle
ahead detection indicator turns off.
If a vehicle ahead appears during acceleration to
the set vehicle speed or any time the ICC system
is in operation, the system controls the distance
to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the system will
be canceled.
When passing another vehicle,
the set speed
indicator
Bwill flash when the vehicle speed
exceeds the set speed. The vehicle detect indi-
cator will turn off when the area ahead of the
vehicle is open. When the pedal is released, the
vehicle will return to the previously set speed.
Even though your vehicle speed is set in the ICC
system, you can depress the accelerator pedal
when it is necessary to accelerate your vehicle
rapidly.

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.

DISTANCE CONTROL ASSIST (DCA)
SYSTEM (if so equipped)
5-72Starting and driving

PRECAUTIONS ON DCA SYSTEM
The system is intended to assist the driver to
maintain an appropriate 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 an appropriate 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.
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.
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 lane
● Motorcycles traveling offset in the travel lane
WARNING
●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
LSD2098
Starting and driving5-73

– On steep downhill roads (frequentbraking 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.
DCA 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. 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,
LSD2098
5-74Starting and driving

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.The detection zone of the sensor is limited. A
vehicle ahead must be in the detection zone for
the system to operate.
A vehicle ahead may move outside of the detec-
tion zone due to its position within the same lane
of travel. Motorcycles may not be detected in the
same lane ahead if they are traveling offset from
the centerline of the lane. A vehicle that is enter-
ing the lane ahead may not be detected until the
vehicle has completely moved into the lane.
If
this occurs, the system may warn you by
blinking the system indicator and sounding
the chime. The driver may have to manually control the proper distance away from ve-
hicle traveling ahead.

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 brak-
ing 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.

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.

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.
