CRUISE CONTROL OPERATIONS
The cruise indicator and the set vehicle
speed are displayed in the vehicle informa-
tion display. The cruise indicator indicates
the staus of the cruise control system by
the color.
The cruise control allows driving at a speed
between 25 to 89 MPH (40 to 144 km/h)
without keeping your foot on the accel-
erator pedal.
To turn on the cruise control,push the
MAIN switch on. The cruise indicator
(white) will come on. To set cruising speed,
accelerate your
vehicle to the desired speed, push the
SET/COAST (-) switch and release it. (The
cruise indicator (green) will illuminates.)
Take your foot off the accelerator pedal.
Your vehicle will maintain the set speed.
. To pass another vehicle, depress the
accelerator pedal. When you release
the pedal, the vehicle will return to the
previously set speed.
. The vehicle may not maintain the set
speed on winding or hilly roads. If this
happens, drive without the cruise con-
trol.
To cancel the preset speed, follow any of
these methods:
1. Push the CANCEL switch.
2. Tap the brake pedal.
3. Turn the MAIN switch off.
After any of the above operation is
performed, the color of the cruise indicator
will change from green to white.
. If you depress the brake pedal while
pushing the RESUME/ACCELERATE (+)
or SET/COAST (-) switch and reset at the
cruising speed, the cruise control will
disengage. Turn the MAIN switch off
once and then turn it on again. .
The cruise control will automatically
cancel if the vehicle slows more than
8 MPH (13 km/h) below the set speed.
. If you move the shift lever to N (Neutral)
position, the cruise control will be
canceled.
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. When the vehicle attains
the speed you desire, release the
switch.
. 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 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. Release the switch when the
vehicle slows down to the desired

speed.
. 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). The Intelligent Cruise Control (ICC) system
maintains a selected distance from the
vehicle in front of you within the speed
range of 0 to 90 MPH (0 to 144 km/h) up to
the set speed. The set speed can be
selected by the driver between 20 to 90
MPH (32 to 144 km/h).
The vehicle travels at a 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.
. In the conventional (fixed speed) cruise
control mode, a warning chime will not
sound to warn you if you are too close to
the vehicle ahead. Pay special attention
to the distance between your vehicle and
the vehicle ahead of you or a collision
could occur.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control
mode, the Intelligent Cruise Control (ICC)
system automatically maintains a selected
distance 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.
With ICC, the driver can maintain the same
speed as other vehicles without the con-
stant need to adjust the set speed as you
would with a normal cruise control system.

PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the radar sensor
*Adetects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance.
The system automatically controls the
throttle and applies the brakes (up to
approximately 40% of vehicle braking power) if necessary.
The detection range of the sensor is
approximately 650 ft (200 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 radar 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
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
(ICC) system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Decelerate the vehicle speed by depres-
sing the brake pedal, depending on the
distance to the vehicle ahead and the
surrounding circumstances in order to
maintain a safe distance between vehi-
cles.
. 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.
. 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 heavyor there are sharp curves
—On slippery road surfaces such ason ice or snow, etc.
—During bad weather (rain, fog, snow,etc.)
—When rain, snow or dirt adhere tothe 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 downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
. 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 ICC system
when it is not recommended in this
section.

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).

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
