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.

control mode,push and hold the MAIN switch
Afor longer than about 1.5 seconds.
When pushing the MAIN switch on, the Intelli-
gent Cruise Control (ICC) system display and the
main switch indicator are displayed on the dot
matrix liquid crystal display. After you hold the
MAIN switch on for longer than about 1.5 sec-
onds, the ICC system display turns off. The main
switch indicator stays lit. You can now set your
desired cruising speed. Pushing the MAIN
switch again will turn the system completely
off. When the Distance Control Assist (DCA) system
is on, the conventional (fixed speed) cruise
control mode cannot be turned on even though
the MAIN switch is pushed and held.
To turn on the conventional (fixed speed) cruise
control mode, turn off the DCA system. See
“DISTANCE CONTROL ASSIST (DCA) SYSTEM”
later in this section.
When the ignition switch is pushed to the OFF
position, the system is also automatically
turned off. To use the ICC system again, quickly
push and release the MAIN switch (vehicle-to-
vehicle distance control mode) or push and hold
it (conventional cruise control mode) again to
turn it on.
CAUTION
To avoid accidentally engaging cruise control,
make sure to turn the MAIN switch off when not
using the ICC system.
To set cruising speed,
accelerate your vehicle to
the desired speed, push the SET/COAST switch
and release it. (The SET indicator will come on in
the display.) Take your foot off the accelerator
pedal. Your vehicle will maintain the set speed.
● To pass another vehicle, depress the accel-
erator pedal. When you release the pedal,
the vehicle will return to the previously set
speed.
● The vehicle may not maintain the set speed
when going up or down steep hills. If this
happens, manually maintain vehicle speed.

and the control is automatically canceled.
● When the vehicle slows down more than 8
MPH (13 km/h) below the set speed
● When the vehicle speed falls below approxi-
mately 20 MPH (32 km/h)
● When the selector lever is shifted to the N
(Neutral) position
● When the parking brake is applied
● When the VDC (including the traction control
system) operates.
● When a wheel slipsWarning 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

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.
DISTANCE CONTROL ASSIST (DCA) SYSTEM
(if so equipped)

Page 388 of 534
PRECAUTIONS ON DISTANCE CONTROL
ASSIST SYSTEM
The system is intended to assist the driver to
keep a following distance from the vehicle
ahead traveling in the same lane and direction.
If the distance sensor
Adetects a slower
moving vehicle ahead, the system will reduce
the vehicle speed to help assist the driver to
maintain a following distance.
The system automatically controls the throttle
and applies the brakes (up to 25% of vehicle
braking power) if necessary. The detection range of the sensor is approxi-
mately 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 follow-
ing 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 dis-
tance control function, never rely solely on
the Distance Control Assist system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding 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 Control Assist sys-
tem 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 on sand or rock, etc.
– During bad weather (rain, fog, snow, etc.)
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
SSD1047
Starting and driving5-63
Page 389 of 534
– When rain, snow or dirt adhere to the sys-tem sensor
– On steep downhill roads (frequent brak- ing may result in overheating the brakes)
– On repeated uphill and downhill roads
– When towing a trailer or other vehicle
● 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 dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the DCA system when it is not recommended
in this section.
DISTANCE CONTROL ASSIST
OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually decelerate to
maintain the proper following distance. The
Distance Control Assist (DCA) system may not
be able to decelerate the vehicle under some
circumstances.
The DCA system uses a sensor
Alocated on
the front of the vehicle to detect vehicles trav-
eling ahead. The sensor generally detects the
signals returned from the reflectors on a vehicle
ahead. Therefore, if the sensor cannot detect
the reflector on the vehicle ahead, the DCA
system may not operate. The following are some conditions in which the
sensor cannot detect the signals:
●
When the reflector of the vehicle ahead is
positioned high on the vehicle (trailer, etc.)
● When the reflector on the vehicle ahead is
missing, damaged or covered
● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When the snow or road spray from traveling
vehicles reduces the sensor’s visibility
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility
● When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the sensor
is covered with dirt or is obstructed, the system
will automatically be canceled. If the sensor is
covered with ice, a transparent or translucent
vinyl bag, etc., the DCA system may not detect
them. In these instances, the Distance Control
Assist (DCA) system may not be able to decel-
erate the vehicle properly. Be sure to check and
clean the sensor regularly.
SSD1047
5-64Starting and driving
Page 390 of 534
The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as
necessary and if the vehicle ahead comes to a
stop, the vehicle decelerates to a standstill.
However, the DCA system can only apply up to
25% of the vehicles total braking power. If a
vehicle moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the DCA system cannot deceler-
ate the vehicle quickly enough. If this occurs,
the DCA system will sound a warning chime and
blink the system display to notify the driver to
take necessary action.
See “Approach warning” later in this section.
This system only brakes and moves the accel-
erator pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.The DCA system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead.
