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 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. 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.
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 canceled.
JVS0211X
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.
How to change the 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
Intelligent Cruise Control system set
indicator (green) 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 SET/COAST (-)
switch.
. Push and hold the RESUME/ACCELER-
ATE (+) switch. The set vehicle speed
will increase by approximately 5 MPH
(5 km/h for Canada).
. Push, then quickly release the RESUME/
ACCELERATE (+) switch. Each time you
do this, the set speed will increase by
approximately 1 MPH (1 km/h for
Canada).

5-70Starting and driving
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 SET/COAST (-) switch and release it.
. Push and hold the SET/COAST (-)
switch. The set vehicle speed will
decrease by approximately 5 MPH (5
km/h for Canada).
. Push, then quickly release the SET/
COAST (-) switch. Each time you do this,
the set speed will decrease by approxi-
mately 1 MPH (1 km/h for Canada).
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 20 MPH (32 km/h).

How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the
traffic conditions.
Each time the DISTANCE switch
*Ais
pushed, the set distance will change to
long, middle, short and back to long again
in that sequence.

JVS0250M
.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 display. Decelerate by
depressing the brake pedal to maintain a
safe vehicle distance if:
.
The chime sounds.
. The vehicle ahead detection and set
distance 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 vehi-
cles is increasing
. When a vehicle cuts in near your vehicle
The warning chime will not sound when:
. Your vehicle approaches other vehicles
that are parked or moving slowly.
. The accelerator pedal is depressed,
overriding the system.

NOTE:
The approach warning chime may sound
and the system display may blink when
the radar sensor detects objects on the
side of the vehicle
*Aor on the side of the
road
*A. This may cause the ICC system to
decelerate or accelerate the vehicle. The
radar sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads or when
entering or exiting a curve. 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 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 shift lever is not in the D
position or Manual mode
. When the parking brake is applied
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode
. When the VDC system is turned off
. When ABS or VDC (including the trac-
tion control system) operates
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor
. When a wheel slips
Warning and display
Condition A:
Under the following conditions, the Intelli-
gent Cruise Control (ICC) system is auto-
matically canceled. The chime will sound
and the “currently unavailable” warning
message will appear in the vehicle infor-
mation display.
. When the VDC is turned off
. When the ABS or VDC (including the
traction control system) operates
. When a tire slips
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode
. When the radar signal is temporarily
interrupted
Action to take:
When the conditions listed above are no
longer present, turn the ICC system back
on to use the system.
Condition B:
When the radar sensor area of the front
bumper is covered with dirt or is ob-
structed, making it impossible to detect a
vehicle ahead, the ICC system is automa-
tically canceled.
The chime will sound and the “front radar

obstruction”warning message will appear
in the vehicle information display.
Action to take:
If the warning message appears, park the
vehicle in a safe place, turn the engine off.
When the radar signal is temporarily
interrupted, clean the sensor area of the
front bumper and restart the engine. If the
“front radar obstruction” warning message
continues to be displayed, have the ICC
system checked by an INFINITI retailer.
JVS0221X
Condition C:
When the ICC system is not operating
properly, the chime sounds and the ICC
system warning (orange) will appear.
Action to take:
If the warning appears, park the vehicle in
a safe place. Turn the engine off, restart the
engine, resume driving and set the ICC
system again.
If it is not possible to set the system or the
warning stays on, it may indicate that the
ICC system is malfunctioning. Although
the vehicle is still driveable under normal
conditions, have the vehicle checked at an INFINITI retailer.
