cruising speed when the vehicle speed is
over 25 MPH (40 km/h). GUID-E7651926-4BC1-4070-A1DC-B90D2ECCC5B1
The Intelligent Cruise Control (ICC) system
automatically maintains a selected dis-
tance from the vehicle traveling in front of
you according to that vehicle ’ s speed (up
to the set speed), or at the set speed when
the road ahead is clear.
The ICC function can be set to one of two
cruise control modes:
. Vehicle-to-vehicle distance control
mode:
For maintaining a selected distance
between your vehicle and the vehicle
in front of you up to the preset speed.
. Conventional (fixed speed) cruise con-
trol mode:
For cruising at a preset speed.
WARNING . Always drive carefully and attentively
when using either cruise control mode.
Read and understand the Owner ’ s Man-
ual thoroughly before using the cruise
control. To avoid serious injury or death,
do not rely on the system to prevent
accidents or to control the vehicle ’ s
speed in emergency situations. Do not
use cruise control except in appropriate
road and traffic conditions.

[ Edit: 2012/ 1/ 17 Model: V36-D ]5-26 Starting and drivingsary.
The detection range of the sensor is
approximately 390 ft (120 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
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. 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 congested areas.
. This system will not adapt automatically
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.
The distance sensor will not detect under
most conditions:
. Stationary and slow moving vehicles
. Pedestrians or objects in the roadway . Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
This system will not automatically brake
the vehicle to a stop.
WARNING . As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. Although the brake operation is con-
trolled by the system, the system does
not automatically stop the vehicle. If the
vehicle speed falls below approximately
20 MPH (32 km/h), the Intelligent Cruise
Control system is automatically canceled
and a warning chime sounds. (The brake
control is also canceled.) . The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the Intelligent Cruise Control 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 the windshield wiper is oper-
ated at the low speed (LO) or high
speed (HI) position, the Intelligent
Cruise Control system is automati-
cally canceled.
— When strong light (for example, at
sunrise or sunset) is directly shining
on the front of the vehicle
— When rain, snow or dirt adhere to
the system sensor
— On steep downhill roads (the vehi-
cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
— On repeated uphill and downhill

System operation GUID-21B82D2D-03FC-4413-BEB2-604A50F67D00
WARNINGNormally 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 properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the brake pedal when deceleration 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 maintains 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: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
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 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 selected distance.
Vehicle ahead not detected: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates 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 accel-
eration to the set vehicle speed or any time

Black plate (355,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]the ICC system is in operation, the system
controls the distance to that vehicle.
SSD0611
When passing another vehicle, the set
speed indicator will flash when the vehicle
speed exceeds the set speed. The vehicle
detect indicator 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.

PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models) GUID-96A87E96-2026-4122-93F8-399D8C784D61
The ICC system with the preview function
identifies 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 ” (P.5-
52).

BRAKING PRECAUTIONS GUID-69469B45-E0A5-4BC3-B99F-C3213CC27874
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Vacuum assisted brakes GUID-95686AE6-7A34-4D3E-9305-085085C76F84
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 pres-
sure 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 GUID-B2433212-C5E2-4B61-9394-8ED34BB6A681
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 GUID-B441C7AD-F0BB-453E-A531-8E92178C3484
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
performance.
This procedure is described in the vehicle
service manual and can be performed by
an INFINITI retailer.
Using the brakes GUID-EB3F3C9C-0F2F-47F8-8239-331D9D489654
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 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.

Self-test feature GUID-EC96AE96-D9F6-4F19-A5A9-937C4D6337A4
The ABS includes electronic sensors, elec-
tric 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 pulsa-
tion 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 operates 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 GUID-36C3BA08-72B5-4E9B-96CF-93CCD7FE6655
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
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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving. GUID-B2222C83-77D9-46CF-971F-591ADE2397C3
The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, the VDC system 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
output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
. 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
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
