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.

(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.

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. Fail-
ure to follow these recommendations may re-
sult in shortened engine life and reduced
engine performance.
c Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
c Do not accelerate at full throttle in any gear.
c Avoid quick starts.
c Avoid hard braking as much as possible. c
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
c Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
c Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
c Select a gear range suitable to road condi-
tions.
c Avoid unnecessary engine idling.
c Keep your engine tuned up.
c Follow the recommended periodic mainte-
nance schedule.
c Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
c Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
c Climate control operation lowers fuel
economy. Use the air conditioner only when
necessary.
c When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag. c
Use the recommended viscosity engine oil.

WARNING
cFor AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any drive or reverse po-
sition with the engine running. Doing so may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
c Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
even if the other two wheels are raised off
the ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with AWD before it is placed on a
dynamometer. Using the wrong test equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
Your vehicle is equipped with full-time All-
Wheel Drive (AWD).
Switching the driving mode is not necessary. The AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position. It
turns off soon after the engine is started.If any malfunction occurs in the AWD system
while the engine is running, the warning light
will come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high powertrain oil temperature. The
driving mode may change to two-wheel drive. If
the warning light blinks rapidly during opera-
tion, stop the vehicle with the engine idling in a
safe place immediately. Then if the light turns
off after a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning
light blink slowly (about once per two seconds).
Pull off the road in a safe area, and idle the
engine. Check that all tire sizes are the same,
tire pressure is correct and tires are not worn.
CAUTION
c
If the warning light remains on after the
above operation, have your vehicle checked
by an INFINITI retailer as soon as possible.
c If the warning light comes on while driving
there may be a malfunction in the AWD sys-
tem. Reduce the vehicle speed and have your
vehicle checked by an INFINITI retailer as
soon as possible.

3. To help prevent the vehicle from rollinginto the street when parked on a sloping
drive way, it is a good practice to turn the
wheels as illustrated.
cHEADED DOWNHILL WITH CURB:s1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
c HEADED UPHILL WITH CURB:
s2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
c HEADED UPHILL OR DOWNHILL, NO CURB:
s3
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 LOCK
position.
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.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.
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.
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.

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 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.
WARNING
cWhile 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.
c 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.
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.
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 (for Intelligent
Cruise Control (ICC) 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.
c This system will not operate when the ve-
hicle is moving at approximately 20 MPH
(32 km/h) or less.

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
cThe Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent ac-
cidents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on nor-
mal 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 responsible for safety.
c Tire type and condition may also affect brak-
ing 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 speci-
fied on the Tire and Loading Information
label. See ªTIRE AND LOADING INFORMA-
TION LABELº in the ª9. Technical and con-
sumer informationº section of this
manual. ± For detailed information, see ªWHEELS
AND TIRESº in the ª8. Maintenance and
do-it-yourselfº 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
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 pres-
sure, 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 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 ªclunkº noise and/or feel a
pulsation in the brake pedal. This is normal and
does not indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.

Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 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
applies 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 pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.When accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the
Vehicle Dynamic Control (VDC) system, sensors
detect these movements and control the brak-
ing and engine output to help improve vehicle
stability.
c
When the VDC system is operating, the
ªSLIPº indicator in the instrument panel
blinks.
c If the ªSLIPº indicator blinks, the road con-
ditions are slippery. Be sure to adjust your
speed and driving to these conditions. Be
sure to drive carefully. (See ªSlip indicator
lightº in the ª2. Instruments and controlsº
section, and ªVehicle Dynamic Control (VDC)
off indicator lightº in the ª2. Instruments
and controlsº section.)
c Indicator light
If a malfunction occurs in the system, the
ªSLIPº and ªVDC OFFº indicator lights illumi-
nate in the instrument panel. As long as
these indicators are illuminated, the VDC
system function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) function to improve vehicle traction.
The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The
ABLS system brakes the spinning wheel, which
distributes the driving power to the other drive wheel. If the vehicle is operated with the VDC
OFF switch pushed and the VDC system turned
off, all VDC systems will be turned off. The ABLS
system and ABS will still operate with the VDC
system off. If the ABLS system is activated, the
ªSLIPº indicator will blink and you may hear a
clunk noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indication of
a malfunction.
While the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise
or feel a vibration from under the hood. This is
normal and indicates that the VDC system is
working properly.
The VDC system computer has a built-in diag-
nostic feature that tests the system each time
you start the engine and move the vehicle at a
low speed forward or backward. When the
self-test occurs, you may hear a ªclunkº noise
and/or feel a pulsation in the brake pedal. This
is normal and is not an indication of a
malfunction.
