System operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically accel-
erates or decelerates your vehicle according to
the speed of the vehicle ahead. Depress the
accelerator to properly accelerate your vehicle
when acceleration is required for a lanechange. Depress the brake pedal when decel-
eration 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 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. Vehicle detected ahead :
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by con-
trolling 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 brak-
ing is performed by the ICC system.
When the brake operates, a noise may be heard
or 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 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 that vehicle.

●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 Intelligent Cruise
Control (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 a vehicle cuts in near your vehicle
The warning chime will not sound in the follow-
ing cases:
● When your vehicle approaches vehicles that
are parked or moving slowly
● When the accelerator pedal is depressed,
overriding the system

is still driveable under normal conditions, have
the vehicle checked at an INFINITI retailer.Sensor maintenance
The sensor for the Intelligent Cruise Control
(ICC) system
Ais located below the front
bumper.
To keep the ICC system operating properly, be
sure to observe the following:
● Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage the
sensor.
● Do not strike or damage 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
damaged due to an accident, contact an
INFINITI retailer.

●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 90 MPH (40 to 144 km/h) without keeping
your foot on the accelerator pedal.
WARNING
● In the conventional (fixed speed) cruise con-
trol 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 be-
tween your vehicle and the vehicle ahead of
you or a collision could occur.
● Always confirm the setting in the Intelligent
Cruise Control (ICC) system display.
● Do not use the conventional (fixed speed)
cruise control mode when driving 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.

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
depresses the brake pedal and helps improve
brake response by reducing pedal free play.
For more details, see “INTELLIGENT CRUISE
CONTROL (ICC) SYSTEM” earlier 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.
