1. System set display with vehicle ahead
2. System set display without vehicle aheadSystem operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically accel-
erates or decelerates your vehicle according to
the speed of the vehicle ahead. Depress the
accelerator to properly accelerate your vehicle
when acceleration is required for a lane
change. Depress the brake pedal when decel-
eration is required to maintain a safe distance
to the vehicle ahead due to its sudden braking
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 con-
trolling 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 brak-
ing 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
selected 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 passing another vehicle,the set speed
indicator will 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.
How to change the set vehicle speed
To cancel the preset speed, use any of these
methods:
● Push the CANCEL switch. The set vehicle
speed indicator will go out. ●
Tap the brake pedal. The set vehicle speed
indicator will go out.
● Turn the MAIN switch off. Both the MAIN
switch indicator and set vehicle speed indi-
cator will go out.
To reset at a faster cruising speed, use one of
the following methods:
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the SET/COAST switch.
● Push and hold the RESUME/ACCELERATE
switch. The set vehicle speed will increase
by approximately 5 MPH (5 km/h for
Canada).
● Push, then quickly release the
RESUME/ACCELERATE switch. Each time you
do this, the set speed will increase by
approximately 1 MPH (1 km/h for Canada).
To reset at a slower cruising speed, use one of
the following methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
SET/COAST switch and release it.
● Push and hold the SET/COAST switch. The
set vehicle speed will decrease by approxi-
mately 5 MPH (5 km/h for Canada).

Each time the DISTANCE switchAis pushed,
the set distance will change to long, middle,
short and back to long again in that sequence. ●
The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the
distance. ●
If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
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 ICC system dis-
play. Decelerate by depressing the brake pedal
to maintain a safe vehicle distance if:
●The chime sounds.
● The vehicle ahead detection and set dis-
tance indicator blink.
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

To set cruising speed,accelerate your vehicle to
the desired speed, push the SET/COAST switch
and release it. (The SET indicator will come on in
the display.) Take your foot off the accelerator
pedal. Your vehicle will maintain the set speed.
● To pass another vehicle, depress the accel-
erator 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 vehicle speed. To cancel the preset speed,
use any of the
following methods:
a) Push the CANCEL button. The SET indica- tor will go out.
b) Tap the brake pedal. The SET indicator will go out.
c) Turn the MAIN switch off. Both the CRUISE indicator and SET indicator will go out.
To reset at a faster cruising speed, use one of
the following three methods:
a) Depress the accelerator pedal. When the vehicle attains the desired speed, push
and release the SET/COAST switch.
b) Push and hold the RESUME/ACCELERATE set switch. When the vehicle attains the
speed you desire, release the switch.
c) 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:
a) Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the SET/COAST switch and release it.
b) Push and hold the SET/COAST switch. Release the switch when the vehicle
slows down to the desired speed. c) Push, then quickly release the SET/COAST
switch. Each time you do this, the set
speed will decrease by about 1 MPH (1.6
km/h).
To resume the preset speed, push and release
the RESUME/ACCELERATE switch. The vehicle
will resume the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h).
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.
● When the vehicle slows down more than 8
MPH (13 km/h) below the set speed
● When the vehicle speed falls below approxi-
mately 20 MPH (32 km/h)
● When the selector lever is not in the D
(Drive), DS (Drive Sport) or manual shift
mode
● When the VDC operates (including the trac-
tion control system)
● When a tire slips

Warning light
When the system is not operating properly, the
chime sounds and the system warning 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, 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 malfunc-
tioning. Although the vehicle is still driveable
under normal conditions, have the vehicle
checked at an INFINITI retailer.
PREVIEW FUNCTION (for Intelligent
Cruise Control 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 more details, see “BRAKE ASSIST” later in
this section.
CAUTION
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle.
Failure to follow these recommendations may
result in shortened engine life and reduced en-
gine 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.

WARNING
●Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
● Never leave the engine running while the
vehicle is unattended.
● Do not leave children unattended inside the
vehicle. They could unknowingly activate
switches or controls. Unattended children
could become involved in serious accidents. ●
Safe parking procedures require that both
the parking brake be applied and the trans-
mission placed into P (Park) for Automatic
Transmission (AT) model or in an appropri-
ate gear for Manual Transmission (MT)
model. Failure to do so could cause the ve-
hicle to move unexpectedly or roll away and
result in an accident.
● Make sure the automatic transmission se-
lector lever has been pushed as far forward
as it can go and cannot be moved without
depressing the foot brake pedal.
1. Firmly apply the parking brake.
2. Automatic transmission models:
Move the selector lever to the P (Park)
position.
Manual transmission models:
Place the shift lever in the R (Reverse) gear.
When parking on an uphill grade, place the
shift lever in the 1st gear.
3. To help prevent the vehicle from rolling
into the street when parked on a sloping
drive way, it is a good practice to turn the
wheels as illustrated.
●HEADED DOWNHILL WITH CURB:1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
● HEADED UPHILL WITH CURB:
2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
● HEADED UPHILL OR DOWNHILL, NO CURB:
3
Turn the wheels toward the side of the road
so the vehicle will move away from the
center of the road if it moves.
4. Push the ignition switch to the OFF posi-
tion.

SONAR SYSTEM OFF SWITCH
The sonar system OFF switch on the instrument
panel allows the driver to turn the sonar system
on and off. To turn the sonar system on and off,
the ignition switch must be in the “ON” posi-
tion. The indicator light
1on the switch will
illuminate when the system is turned off. If the
indicator light flashes when the sonar system is
not turned off, it may indicate a malfunction in
the sonar system.
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.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
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. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle and the
stopping distance will be longer.
When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
slight pulsation. This is normal and indicates
that the Brake Assist System is operating.
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 weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
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 care-
ful when braking, accelerating or downshift-
ing. 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.
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 responsibil-
ity 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 ve-
hicle 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 reducing pedal free play.
● This system will not operate when the ve-
hicle is moving at approximately 20 MPH
(32 km/h) or less.
