control the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or
vehicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed.
.When the vehicle ahead is not detected
and your vehicle is traveling below the
speed of 15 MPH (24 km/h)
. When the system judges the vehicle is at
standstill
. When the shift lever is not in the D
position or Manual mode
. When the parking brake is applied
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode
. When the VDC system is turned off
. When ABS or VDC (including the traction
control system) operates
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor
. When a wheel slips .

Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The system is primarily intended for
use on straight, dry, open roads with
light traffic. It is not advisable to use
the system in city traffic or con-
gested areas.
. This system will not adapt automati-
cally to road conditions. This system
should be used in evenly flowing
traffic. Do not use the system on
roads with sharp curves, or on icy
roads, in heavy rain or in fog.
. 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 absent-minded driving, or over-
come poor visibility in rain, fog, or other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between 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 opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain
the selected distance between vehi-
cles (following distance) or selected
vehicle speed under some circum-
stances.
. The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the ICC system
under the following conditions:

5-90Starting and driving
system completely off.
When the ignition switch is placed in the
OFF position, the system is also automati-
cally turned off.
To use the ICC system again, quickly push
and release the MAIN switch (vehicle-to-
vehicle distance control mode) or push and
hold it (conventional cruise control mode)
again to turn it on.
When the Distance Control Assist (DCA)
system is on, the conventional (fixed speed)
cruise control mode cannot be turned on
even though the MAIN switch is pushed and
held.
To turn on the conventional (fixed speed)
cruise control mode, turn off the DCA
system. See “Distance Control Assist
(DCA)” (P.5-92).
CAUTION
To avoid accidentally engaging cruise
control, make sure to turn the MAIN
switch off when not using the ICC
system.

To set cruising speed,accelerate your
vehicle to the desired speed, push the SET/
COAST (-) switch and release it. (The color
of the cruise indicator changes to green and
set vehicle speed indicator comes on.) Take
your foot off the accelerator pedal. Your
vehicle will maintain the set speed.
. To pass another vehicle, depress the
accelerator pedal. When you release the
pedal, the vehicle will return to the
previously set speed.
. The vehicle may not maintain the set
speed when going up or down steep hills.
If this happens, manually maintain vehi-
cle speed. To cancel the preset speed,
use any of the
following methods:
1. Push the CANCEL switch. The vehicle speed indicator will turn off.
2. Tap the brake pedal. The vehicle speed indicator will turn off.
3. Turn the MAIN switch off. Both the cruise indicator and vehicle speed indi-
cator will turn off.
To reset at a faster cruising speed, use one
of the following three methods:
1. Depress the accelerator pedal. When the vehicle attains the desired speed, push
and release the SET/COAST (-) switch.
2. Push and hold the RESUME/ACCELER- ATE (+) switch. When the vehicle attains
the desired speed, release the switch.
3. Push, then quickly release the RESUME/ ACCELERATE (+) switch. Each time you
do this, the set speed will increase by
about 1 MPH (1.6 km/h).
To reset at a slower cruising speed, use one
of the following three methods:
1. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
the SET/COAST (-) switch and release it.
2. Push and hold the SET/COAST (-) switch. Release the switch when the
vehicle slows down to the desired speed.

The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelera-
tor pedal upward in the normal driving
condition.
When a vehicle ahead is detected:
The vehicle ahead detection indicator ap-
pears. When the vehicle approaches a vehicle
ahead:
.
If the driver’s foot is not on the accel-
erator pedal, the system activates the
brakes to decelerate smoothly as neces-
sary. If the vehicle ahead comes to a
stop, the vehicle decelerates to a stand-
still within the limitations of the system.
. If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward to assist the driver to
release the accelerator pedal.
When brake operation by the driver is
required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead detec- tion indicator. If the driver’s foot is on the
accelerator pedal after the warning, the
system moves the accelerator pedal upward
to assist the driver to switch to the brake
pedal.
NOTE:
.
The stop lights 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.
Overriding the system:
The following driver’s operation overrides
the system operation.
. When the driver depresses the accelera-
tor pedal even further while the system is
moving the accelerator pedal upward,
the DCA system control of the accel-
erator pedal is canceled.
. When the driver’s foot is on the accel-
erator 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 Intelligent Cruise Control (ICC)
system is set, the DCA system will be
inactive.

FEB SYSTEM OPERATION
The FEB system operates at speeds above
approximately 3 MPH (5 km/h).
If a risk of a forward collision is detected, the
FEB system will provide the first warning to
the driver by flashing the driver assist system
forward indicator (orange)
and the vehicle
ahead detection indicator (orange), and
providing an audible warning. In addition,
the FEB system pushes the accelerator
pedal up. If the driver releases the accel-
erator pedal, then the system applies partial
braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB
system detects that there is still the possi-
bility of a forward collision, the system will
automatically increase the braking force.
If a forward collision is imminent and the
driver does not take action, the FEB system
issues the second visual (red) and audible
warning and automatically applies harder
braking.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB system.
Depending on vehicle speed and distance to
the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may

help mitigate the consequences of a collision
should one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB system will
function later or will not function.
The automatic braking will cease under the
following conditions:
.When the steering wheel is turned as far
as necessary to avoid a collision.
. When the accelerator pedal is depressed.
. When there is no longer a vehicle de-
tected ahead.
If the FEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the brakes
are released.

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy
of your new vehicle.
Failure to follow these recommendations
may result in shortened engine life and
reduced engine performance.
. Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
. Do not accelerate at full throttle in any
gear.
. Avoid quick starts.
. Avoid hard braking as much as possible. Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1. Use smooth accelerator and brake pedal
application.
.Avoid rapid starts and stops..Use smooth, gentle accelerator andbrake application whenever possible.
.Maintain constant speed while com-muting and coast whenever possible.
2. Maintain constant speed.
.Look ahead to try and anticipate and minimize stops.
.Synchronizing your speed with traffic
lights allows you to reduce your
number of stops.
.Maintaining a steady speed can mini-mize red light stops and improve fuel
efficiency.
3. Use air conditioning (A/C) at higher vehicle speeds.
.Below 40 MPH (64 km/h), it is moreefficient to open windows to cool the
vehicle due to reduced engine load.
.Above 40 MPH (64 km/h), it is moreefficient to use A/C to cool the
vehicle due to increased aerodynamic
drag.
.Recirculating the cool air in the cabinwhen the A/C is on reduces cooling
load.

To return the steering wheel to the normal
position, stop the vehicle in a safe location
and stop operating the steering wheel. Then
drive the vehicle for a short period of time.
Condition B
. When the steering wheel is operated
repeatedly or continuously while parking
or driving at a very low speed. In this
case, the power assist for the steering
wheel will be reduced.
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and wait for a period of time, without
operating the steering wheel, until the
temperature of Direct Adaptive Steering
cools down. Avoid repeated steering wheel
operations that could cause Direct Adaptive
Steering to overheat.
When the vehicle is tested on the 2-wheel
dynamometer, the power steering warning
light may illuminate. To turn off the power
steering warning light, stop the vehicle in a
safe location, turn the engine off, restart the
engine, and then drive the vehicle for a
period of time.
The following conditions do not indicate a
malfunction of Direct Adaptive Steering.
. You may notice wider steering play when
the ignition switch is in the OFF or ACC
position compared to when it is in the ON position.
. After the engine is started, the steering
wheel may turn slightly even when
driving on a straight road. To return to
the normal position, drive the vehicle on
a straight road for a period of time.
. After the engine is started, the steering
wheel may move if the steering wheel
was turned to the fully locked position
while the ignition switch was in the OFF
position.
. After the vehicle is tested on the 4-wheel
dynamometer, the steering wheel may
turn slightly even when driving on a
straight road. To return the steering
wheel to the normal position, drive the
vehicle on a straight road for a period of
time.
You may hear a noise under the following
conditions. However, this is not a malfunc-
tion.
. When the engine is started or stopped.
. When the steering wheel is turned in the
full lock position.BRAKING PRECAUTIONS
The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
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 the stopping distance will be
longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating of
the brakes, wearing out the brake and pads
faster and reduce gas mileage.
To help save the brakes 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.
WARNING
. While driving on a slippery surface,
be careful when braking, accelerating
BRAKE SYSTEM

or downshifting. Abrupt braking or
accelerating 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 brakes, drive the vehicle at a safe
speed while lightly tapping 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 stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced, in
order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended you visit an INFINITI retailer for this service.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional 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
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
.
The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that
stopping distances on slippery sur-
Starting and driving5-127
BRAKE ASSIST

5-128Starting and driving
faces will be longer than on normal
surfaces even with ABS. Stopping
distances 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 responsible 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. See
“Tire and loading information la-
bel” (P.10-13) of this manual.
— For detailed information, see “Wheels and tires” (P.8-26) 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 prevent 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 slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid
obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
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 mal-function, 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 you visit
an INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. 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 indi-
cate that road conditions are hazardous and
extra care is required while driving.
