∙ As there is a performance limit to the Pre-view Function, never rely solely on this
system. This system does not correct
careless, inattentive or absentminded
driving, or overcome poor visibility 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 following
conditions. The vehicle is still driveable
under normal conditions and the Brake
Assist will operate.
– When rain or snow adhere to the bum- per around the distance sensor.
– 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.
Conventional (fixed speed) cruise
control mode
This mode allows driving at a speed between
20 to 90 mph (32 to 144 km/h) without
keeping your foot on the accelerator pedal.
WARNING
∙ In the conventional (fixed speed) cruisecontrol mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the presence
of the vehicle ahead nor the vehicle-to-
vehicle distance is detected.
∙ Pay special attention to the distance be- tween your vehicle and the vehicle ahead
of you or a collision could occur.
∙ Always confirm the setting in the Intelli- gent Cruise Control system display.
∙ Do not use the conventional (fixed speed) cruise control mode when driving under
the following conditions:
– When it is not possible to keep the ve- hicle at a set speed
– In heavy traffic or in traffic that varies in speed
– On winding or hilly roads
– On slippery roads (rain, snow, ice, etc.)
– In very windy areas
∙ Doing so could cause a loss of vehicle con- trol and result in an accident.
THE ICC SWITCH
The system is operated by the CRUISE
ON/OFF switch and four control switches,
all mounted on the steering wheel.
1. ACCEL/RES switch:
Resumes set speed or increases speed
incrementally.
2. COAST/SET switch:
Sets desired cruise speed or reduces
speed incrementally.

1System set display with vehicle ahead
2System set display without vehicle ahead
Vehicle detected ahead
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by
controlling 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 dis-
tance. NOTE:
∙ 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
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 accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 mph (24 km/h), the system
will be canceled.

∙ As there is a performance limit to the dis-tance control function, never rely solely
on the ICC system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding 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 operation of the vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(following distance) or selected vehicle
speed under some circumstances. ∙ The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the ICC system under the following
conditions:
– On roads where the traffic is heavy or there are 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 bumper around the distance sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources.
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead. ∙ In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert and
avoid using the ICC system where not
recommended in this warning section.
The radar 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
The following are some conditions in which
the sensor cannot properly detect a vehicle
ahead and the system may not operate prop-
erly: ∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ When excessively heavy baggage is loaded in the rear seat or the cargo area
of your vehicle.
The ICC system is designed to automatically
check the sensor’s operation within the limi-
tations of the system.

WARNING
∙ While driving on a slippery surface, becareful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating 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 cor-
rectly.
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 rotors are replaced, in order to
assure the best brake performance. This procedure is described in the INFINITI
Service Manual. It is recommended that you
visit an INFINITI retailer for this service.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
∙ The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving techniques.
It can help maintain vehicle control dur-
ing 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 responsible
for safety.
∙ Tire type and condition may also affect braking effectiveness.
– When replacing tires, install the speci- fied 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 In-
formation label. For additional infor-
mation, refer to “Tire and Loading In-
formation label” in the “Technical and
consumer information” section of this
manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself” section of this manual.
The 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
Anti-lock Braking System will operate to pre-
vent the wheels from locking up. Steer the
vehicle to avoid obstacles.
Starting and driving5-135

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 fea-
ture 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 mal-
function. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates
the ABS warning light on the instrument
panel. The brake system then operates nor-
mally 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 that you visit an
INFINITI retailer for this service.
Normal operation
The Anti-lock Braking System (ABS) operates
at speeds above3-6mph(5-10km/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 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 prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.
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 driv-
er’s responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
The VDC system uses various sensors to
monitor driver inputs and vehicle motion. Un-
der certain driving conditions, the VDC sys-
tem helps to perform the following functions:
∙ Controls brake pressure to reduce wheel slip on one slipping drive wheel so power
is transferred to a non-slipping drive
wheel on the same axle.
∙ Controls brake pressure and engine out- put to reduce drive wheel slip based on
vehicle speed (traction control function).
∙ Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
– Understeer (vehicle tends to not fol- low the steered path despite in-
creased steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving situ-
ations.
