System operation
WARNING
Normally 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 Intelligent Cruise Control (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:
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 and/or vibration may be felt. 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 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.

5-68Starting and driving
If a vehicle ahead appears during accel-
eration to the set vehicle speed or any time
the ICC system is in operation, the system
controls the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the
system will be cancelled.

When passing another vehicle,the set
vehicle 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.
How to change 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
indicator 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 COAST/SET
switch.
. Push and hold the ACCELERATE/RE-
SUME switch. The set vehicle speed
will increase by approximately 5 MPH
or 5 km/h.
. Push, then quickly release the ACCEL-
ERATE/RESUME switch. Each time you
do this, the set speed will increase by
approximately 1 MPH or 1 km/h.
To reset at a slower cruising speed, use
one of the following methods:
. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
the COAST/SET switch and release it.
. Push and hold the COAST/SET switch.
The set vehicle speed will decrease by

NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects some reflectors
*A
which 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 detect
these reflectors when the vehicle is driven
on winding roads, hilly roads or when
entering or exiting a curve. The ICC sensor
may also detect reflectors on narrow roads
or in road construction 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 condition (for example, if a vehicle
is being driven with some damage).
Automatic cancellation
A chime sounds under the following con-
ditions and the control is automatically
canceled.
.
When the vehicle speed falls below
approximately 15 MPH (24 km/h)
. When the system judges the vehicle is
at a standstill
. When the shift lever is shifted to the N
(Neutral) position
. When the windshield wipers are operat-
ing at high speed. The system may
cancel when the wipers are set to the
AUTO position.
. When the VDC is turned off
. When the ABS or VDC operates
. When the parking brake is applied
. When the SNOW mode switch is pushed
on.
. When the 4WD shift switch is in the 4H

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
malfunctioning. Although the vehicle is
still driveable under normal conditions,
have the vehicle checked at an INFINITI retailer.
PREVIEW FUNCTION (for Intelligent
Cruise Control (ICC) system
equipped model)
The Intelligent Cruise Control (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 de-
presses the brake pedal and helps improve
brake response by reducing pedal free
play.
For more details, see
“Brake assist”later in
this section.
Starting and driving5-77

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.
. 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
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
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Distance Control Assist
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.
. The system may not function properly
under the following conditions. To avoid
accidents, never use the Distance Con-
trol Assist system under the following
conditions:
—On roads with sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—On off-road surfaces such as onsand or rock, etc.
—During bad weather (rain, fog, snow,etc.)
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (frequent
braking may result in overheating
the brakes)
—On repeated uphill and downhillroads
—When towing a trailer or othervehicle
. 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 distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.

System operation
WARNING
The Distance Control Assist system auto-
matically decelerates your vehicle to help
assist the driver to maintain a following
distance from the vehicle ahead. Manually
brake when deceleration 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 limitations of the
system.
. If the driver’s foot is on the accelerator
pedal, the system moves the accelera-
tor pedal upward to assist the driver to
release the accelerator pedal.
When brake operation by driver is re-
quired:
The system alerts the driver by a warning
chime and blinking the vehicle ahead
detection indicator. 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
when braking is performed by the DCA
system.
When the brake operates, a noise may be
heard and/or vibration may be felt. This is
not a malfunction.

For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system” 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 approxi-
mately 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.
