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 prop-
erly accelerate your vehicle when accel-
eration is required for a lane change. De-
press the brake pedal when deceleration
is required to maintain a safe distance to
the vehicle ahead due to its sudden brak-
ing 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 main-
tains 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. The
CRUISE indicator light in the vehicle information
display comes on.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead, the
ICC system decelerates the vehicle by control-
ling 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 a driver
selected distance.
The stoplights of the vehicle come on and
the brake pedal depresses when braking is
performed by the ICC system.
CAUTION
Never place your foot under the brake
pedal, when the brake is operated by the
Intelligent Cruise Control system. You
may get your foot caught in the pedal.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and se-
lected distance.
Vehicle ahead not detected:
When a vehicle is no longer detected ahead, the
ICC system gradually accelerates 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 acceleration to
the set vehicle speed or any time the ICC system
is in operation, the system controls the distance
to the vehicle.

When passing another vehicle,the set speed
indicator will flash when the vehicle speed ex-
ceeds 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. The CRUISE
indicator light will appear on the vehicle informa-
tion display.
Although your vehicle may be at the set vehicle
speed based on ICC system control, depress the
accelerator pedal when it is necessary to accel-
erate 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 ON/OFF switch off. Both the
ON/OFF 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 ACCEL/RES switch. The
set vehicle speed will increase by approxi-
mately 5 MPH (5 km/h for Canada) .
● Push, then quickly release the ACCEL/RES
switch. Each time you do this, the set speed
will increase by approximately 1 MPH (1
km/h for Canada) . To reset at a slower cruising speed,
use one
of the following methods:
● Lightly tap the brake pedal. When the ve-
hicle 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 approxi-
mately 5 MPH (5 km/h for Canada) .
● Push, then quickly release the COAST/SET
switch. Each time you do this, the set speed
will decrease by approximately 1 MPH (1
km/h for Canada) .
To resume the preset speed, push and re-
lease the ACCEL/RES switch. The vehicle will
resume the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h) .

How to change the set distance to the
vehicle ahead
The distance to the vehicle ahead can be se-
lected at any time depending on the traffic con-
ditions.
Each time the DISTANCE switch is pressed, the
set distance will change to long, medium, short
and back to long again in that sequence.●
The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the dis-
tance.
● If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
● The CRUISE indicator light will appear in the
vehicle information display.
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 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 the accelerator pedal is depressed,
overriding the system.
● 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.

NOTE:
The approach warning chime may sound
and the system display may blink when the
ICC sensor detects some reflectors
1
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 en-
tering 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 the traffic condition (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 speed falls below approxi-
mately 20 MPH (32 km/h)
● When the selector lever is shifted to a posi-
tion other than D (Drive) , 4, 3, 2, or 1, includ-
ing the manual shift mode ●
When the wiper is operated
● When the parking brake is applied
● When the VDC is turned off
● When the VDC operates

tions, have the vehicle checked at an
INFINITI dealer.
Sensor maintenance
The sensor for the ICC system1is located
below the front bumper.
To keep the ICC system operating properly, be
sure to observe the following:

●Do not impact the areas around the sensor.
Do not touch or remove the screw located
on the sensor. Doing so could cause failure
or malfunction. If the sensor is deformed due
to an accident, contact an INFINITI dealer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
CONVENTIONAL (FIXED SPEED)
CRUISE CONTROL MODE
This mode allows driving at a speed between 25
to 89 MPH (40 to 144 km/h) without keeping
your foot on the accelerator pedal.
WARNING
● In the conventional (fixed speed) cruise
control mode, a warning chime does
not sound to warn you if you are too
close to the vehicle ahead, as neither
the presence of the vehicle ahead nor
the vehicle-to-vehicle distance is
detected.
● Pay special attention to the distance
between your vehicle and the vehicle
ahead of you or a collision could occur. ●
Always confirm the setting in the Intel-
ligent Cruise Control system display.
● Do not use the conventional (fixed
speed) cruise control mode when driv-
ing under the following conditions:
– When it is not possible to keep the vehicle at a set speed.
– In heavy traffic or in traffic that varies in speed.
– On winding or hilly roads.
– On slippery roads (rain, snow, ice, etc.) .
– In very windy areas.
Doing so could cause a loss of vehicle
control and result in an accident.
