brake INFINITI FX 2010 Workshop Manual

●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
The warning chime will not sound when:
● the vehicle approaches other vehicles that
are parked or moving slowly.
● the accelerator pedal is depressed, overrid-
ing the system.

NOTE:
The approach warning chime may sound and the
system display may blink when the ICC sensor
detects some reflectors
Awhich are fitted on
vehicles in other lanes or on the side of the road.
This may cause the ICC system to decelerate or
accelerate the vehicle. The ICC sensor may de-
tect these reflectors when the vehicle is driven
on winding roads, hilly roads or when entering
or exiting a curve. The ICC sensor may also de-
tect reflectors on narrow roads or in road con-
struction zones. In these cases you will have to
manually 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 condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.
●
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 selector lever is not in the D, DS or
Manual mode
● When the windshield wipers are operating at
low (LO) or high speed (HI). If the vehicle is
equipped with a rain sensing auto-wiper, the
system may cancel when the wipers are set
to intermittent (INT).
● When the parking brake is applied
● When the SNOW mode switch is turned ON
● When the VDC system is turned off
● When ABS or VDC (including the traction
control system) operates ●
When driving into a strong light (i.e., sun-
light)
● When distance measurement becomes im-
paired due to adhesion of dirt or obstruction
to the sensor
● When a wheel slips

b) Tap the brake pedal. The SET indicatorwill 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
Under the following condition, a chime will
sound and the system 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, DS or
Manual mode
● When the parking brake is applied
● When the VDC (including the traction control
system) operates
● When a wheel 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.The Distance Control Assist (DCA) system
brakes and moves the accelerator pedal upward
according to the distance from and the relative
speed of the vehicle ahead to help assist the
driver to maintain a following distance.
WARNING
●
Always drive carefully and attentively when
using the Distance Control Assist system.
Read and understand the Owner’s Manual
thoroughly before using the DCA system. 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 the Distance Control Assist sys-
tem except in appropriate road and traffic
conditions.
● 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 with a warning chime. To
prevent the vehicle from moving, the driver
must depress the brake pedal.
● The DCA system will not apply brake control
while the driver’s foot is on the accelerator
pedal.
PRECAUTIONS ON DISTANCE CONTROL
ASSIST SYSTEM
The system is intended to assist the driver to
keep a following distance from the vehicle
ahead traveling in the same lane and direction.
If the distance sensor
Adetects a slower
moving vehicle ahead, the system will reduce
the vehicle speed to help assist the driver to
maintain a following distance.
The system automatically controls the throttle
and applies the brakes (up to 25% of vehicle
braking power) if necessary.
The detection range of the sensor is approxi-
mately 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.
● This system will not adapt automatically to
road conditions. 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 the follow-
ing 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
WARNING
● As there is a performance limit to the dis-
tance control function, never rely solely on
the Distance Control Assist system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances 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 condi-
tions. To avoid accidents, never use the Dis-
tance Control Assist system under the fol-
lowing conditions:
– On roads with sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor – On steep downhill roads (frequent brak-
ing may result in overheating the brakes)
– On repeated uphill and downhill roads
● Do not use the Distance Control Assist sys-
tem if you are towing a trailer. The system
may not detect a vehicle ahead.
● In some road or traffic conditions, a vehicle
or object can unexpectedly come into the
sensor detection zone and cause automatic
braking. You may need to control the dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the DCA system when it is not recommended
in this section.

DISTANCE CONTROL ASSIST
OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually decelerate to
maintain the proper following distance. The
Distance Control Assist (DCA) system may not
be able to decelerate the vehicle under some
circumstances.
The DCA system uses a sensor
Alocated on
the front of the vehicle to detect vehicles trav-
eling ahead. The sensor generally detects the
signals returned from the reflectors on a vehicle
ahead. Therefore, if the sensor cannot detect
the reflector on the vehicle ahead, the DCA
system may not operate. The following are some conditions in which the
sensor cannot detect the signals:
●
When the reflector of the vehicle ahead is
positioned high on the vehicle (trailer, etc.)
● When the reflector on the vehicle ahead is
missing, damaged or covered
● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When the snow or road spray from traveling
vehicles reduces the sensor’s visibility
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility
● When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the sensor
is covered with dirt or is obstructed, the system
will automatically be canceled. If the sensor is
covered with ice, a transparent or translucent
vinyl bag, etc., the DCA system may not detect
them. In these instances, the Distance Control
Assist (DCA) system may not be able to decel-
erate the vehicle properly. Be sure to check and
clean the sensor regularly. The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as
necessary and if the vehicle ahead comes to a
stop, the vehicle decelerates to a standstill.
However, the DCA system can only apply up to
25% of the vehicles total braking power. If a
vehicle moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the DCA system cannot deceler-
ate the vehicle quickly enough. If this occurs,
the DCA system will sound a warning chime and
blink the system display to notify the driver to
take necessary action.
See “Approach warning” later in this section.
This system only brakes and moves the accel-
erator pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.
The DCA system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead.

WARNING
The Distance Control Assist system automati-
cally decelerates your vehicle to help assist the
driver to maintain a following distance from the
vehicle ahead. Manually brake when decelera-
tion is required to maintain a safe distance
upon sudden braking by the vehicle ahead or
when a vehicle suddenly appears in front of
you. Always stay alert when using the DCA
system.The Distance Control Assist (DCA) system helps
assist the driver to keep a following distance to
the vehicle ahead by braking and moving the
accelerator pedal upward in the normal driving
condition.
When a vehicle is detected ahead :
The vehicle ahead detection indicator comes
on.
When vehicle approaches a vehicle ahead :
●
If the driver’s foot is not on the accelerator
pedal, the system activates the brakes to
decelerate smoothly as necessary. If the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill within the limita-
tions 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 driver is required :
The system alerts the driver by a warning chime
and blinking the vehicle ahead detection indi-
cator. 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.

The stoplights of the vehicle come on and the
brake pedal depresses when braking is per-
formed by the DCA system.
When the brake operates, a noise may be heard.
This is not a malfunction.
WARNING
●When the vehicle ahead detection indicator
light is not illuminated, system will not con-
trol or warn the driver.
● Never place your foot under the brake pedal.
Your foot may be caught when the system
controls the brake.
● Depending on the position of the accelerator
pedal, the system may not be able to assist
the driver to release the accelerator pedal
appropriately.
● If the vehicle ahead comes to a standstill,
the vehicle decelerates to a standstill within
the limitations of the system. The system
will release brake control with a warning
chime once it judges the vehicle is at a
standstill. To prevent the vehicle from mov-
ing, the driver must depress the brake pedal.
(The system will resume control automati-
cally once the system reaches 3 MPH
(5 km/h)). Overriding the system :
The following driver’s operation overrides the
system operation.
●
When the driver depresses the accelerator
pedal even further while the system is mov-
ing the accelerator pedal upward, the DCA
system control of the accelerator pedal is
canceled.
● When the driver’s foot is on the accelerator
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 system is
set, the DCA system will be cancelled.
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 DCA system
display. Decelerate by depressing the brake
pedal to maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection indicator blinks.
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
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.

– When abruptly accelerating ordecelerating.
– On a steep downhill slope or on roads with sharp curves.
– When there is a highly reflective object near the vehicle ahead (i.e., being very
close to another vehicle, signboard, etc.)
– When you are towing a trailer.
● Depending on certain road conditions
(curved or beginning of a curve), vehicle con-
ditions (steering position or vehicle posi-
tion), or the preceding vehicle’s conditions
(position in lane, etc.), the system may not
function properly. The system may detect
highly reflective objects such as reflectors,
signs, white markers, and other stationary
objects on the road or near the traveling lane
and provide unnecessary warning.
● The system may not function in offset
conditions.
● The system may not function when the dis-
tance to the vehicle ahead is extremely
close. ●
The system is designed to automatically
check the sensor’s functionality. If the sen-
sor is covered with ice, a transparent or
translucent plastic bag, etc., the system may
not detect them. In these instances the sys-
tem may not be able to warn the driver prop-
erly. Be sure to check and clean the sensor
regularly.
● Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
● A sudden appearance of a vehicle in front
(i.e., it abruptly cuts in) may not be detected
and the system may not warn the driver soon
enough.
● The system will be cancelled automatically
with a beep sound and the IBA OFF indicator
light will illuminate under the following
conditions:
– When the sensor window is dirty
– When the system malfunctions If the IBA OFF indicator light
Ailluminates with
a beep sound, pull off the road to a safe
location, stop the vehicle and turn the engine
off. Check to see if the sensor window is dirty.
If the sensor window is dirty, clean it with a soft
cloth and restart the engine. If the sensor
window is not dirty, restart the engine. If the
IBA OFF indicator light continues to illuminate
even if the IBA system is turned on with the IBA
OFF switch
B, have the system checked by an
INFINITI retailer.
To turn on the IBA system, see “INTELLIGENT
BRAKE ASSIST (IBA) SYSTEM” later in this sec-
tion.

FCW system operation
The FCW system will function at speeds of
approximately 10 MPH (15 km/h) and above,
when the system turns on.
The FCW system has an automatic setting mode
and a manual setting mode to turn the system
on. The setting mode can be changed. In the
automatic setting mode, the FCW system is
automatically turned on when the ignition
switch is pushed to the ON position. When the
FCW system is on, the FCW/LDW ON indicator
light
1on the FCW/LDW switch illuminates. To
cancel the FCW system, push the FCW/LDW
switch. The FCW/LDW ON indicator light will turn off. To turn on the system, push the
FCW/LDW switch again.
When the FCW switch is pushed, the LDW
system will also turn on or off simultaneously.
See “LANE DEPARTURE WARNING (LDW) SYS-
TEM” earlier in this section.
In the manual setting mode, you need to push
the FCW/LDW switch to turn on the system after
the ignition switch is pushed to the ON posi-
tion.
The setting mode can be changed using the
FCW/LDW switch. To change the setting mode,
push and hold the FCW/LDW switch for more
than 4 seconds when the FCW/LDW ON indica-
tor is off. When the mode is changed, a chime
sounds and the lane departure warning light
(orange) flashes.
For the sensor maintenance, see “INTELLIGENT
CRUISE CONTROL (ICC) SYSTEM (FULL SPEED
RANGE)” earlier in this section.
The Intelligent Brake Assist (IBA) system warns
the driver by a warning light and chime when
there is a risk of a collision with the vehicle
ahead in the traveling lane and the driver must
take avoidance action immediately. The system
helps reduce the rear-end collision speed by
applying the brakes when the system judges
that the collision cannot be prevented.
The IBA system will function when your vehicle
is driven at speeds of approximately 10 MPH (15
km/h) and above, and when your vehicle is
driven at speeds approximately 10 MPH (15
km/h) faster than the vehicle ahead.
