VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control mode,
the ICC system automatically maintains a se-
lected 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 constant
need to adjust the set speed as you would with a
normal cruise control system.
PRECAUTIONS ON VEHICLE-TO-
VEHICLE 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 distance sensor
Adetects a slower mov-
ing 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 40% of vehicle
braking power) if necessary. The detection range of the sensor is approxi-
mately 490 ft (150 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 re-
sponsibility 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 distance sensor will not detect the following
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
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive or
absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween vehicles.
● 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 heavy or there are sharp curves – On slippery road surfaces such as on
ice or snow.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
● Do not use the ICC system if you are
towing a trailer. The system may not
detect a vehicle ahead. ●
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. Al-
ways stay alert and avoid using the ICC
system where not recommended in this
warning section.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of the ve-
hicle and be ready to manually control the proper
following distance. The vehicle-to-vehicle dis-
tance control mode of the ICC system may not be
able to maintain the selected distance between
vehicles (following distance) or selected vehicle
speed under some circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
Alocated behind the front bum-
per of the vehicle to detect vehicles traveling
ahead. The sensor generally detects the signals
returned from the vehicle ahead. Therefore, if the sensor cannot detect the reflection from the ve-
hicle ahead, the ICC system may not maintain the
selected distance.
The following are some conditions in which the
sensor cannot detect the signals:
● When snow or road spray from traveling
vehicles reduces the sensor’s visibility
● When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The ICC system is designed to automatically
check the sensor’s operation within the limitation
of the system. When the front bumper area
around the distance sensor is obstructed, the
system will automatically cancel. If the front bum-
per area around the distance sensor is covered
with ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them. In
these instances, the vehicle-to-vehicle distance
control mode may not cancel and may not be able
to maintain the selected following distance from
the vehicle ahead. Be sure to check and clean the
front bumper area around the distance sensor
regularly.
The vehicle-to-vehicle distance control mode is
designed to maintain a selected distance and
reduce the speed to match the slower vehicle
ahead. The system will decelerate the vehicle as necessary and if the vehicle ahead comes to a
stop, the vehicle decelerates to a standstill. How-
ever, the ICC system can only apply up to 40% of
the vehicle’s total braking power. This system
should only be used when traffic conditions allow
vehicle speeds to remain fairly constant or when
vehicle speeds change gradually. 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 ICC system cannot decelerate the vehicle
quickly enough. If this occurs, the ICC system will
sound a warning chime and blink the system
display to notify the driver to take necessary
action.
The system will cancel and a warning chime will
sound if the speed is below approximately
15 MPH (24 km/h) and a vehicle is not detected
ahead. The system will also disengage when the
vehicle goes above the maximum set speed.
For additional information, refer to “Approach
warning” in this section.

5-56Starting and driving

The detection zone of the ICC sensor is limited. A
vehicle ahead must be in the detection zone for
the vehicle-to-vehicle distance detection mode
to maintain the selected distance from the vehicle
ahead.
A vehicle ahead may move outside of the detec-
tion zone due to its position within the same lane
of travel. Motorcycles may not be detected in the
same lane ahead if they are traveling offset from
the centerline of the lane. A vehicle that is enter-
ing the lane ahead may not be detected until the
vehicle has completely moved into the lane.If
this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime. The driver may have to manually control the proper distance away
from the vehicle traveling ahead.

5-58Starting and driving

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the ICC sensor may detect
vehicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may cause
the ICC system to decelerate or accelerate the
vehicle.
The detection of vehicles may also be affected by
vehicle operation (steering maneuver or traveling
position in the lane, etc.) or vehicle condition.If
this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime unexpectedly. You will have to manually control the proper dis-
tance away from the vehicle traveling
ahead.
When driving on the freeway at a set speed and
approaching a slower traveling vehicle ahead, the
ICC will adjust the speed to maintain the dis-
tance, selected by the driver, from the vehicle
ahead. If the vehicle ahead changes lanes or exits
the freeway, the ICC system will accelerate and
maintain the speed up to the set speed. Pay
attention to the driving operation to maintain con-
trol of the vehicle as it accelerates to the set
speed.
The vehicle may not maintain the set speed on
winding or hilly roads. If this occurs, you will have
to manually control the vehicle speed.

Starting and driving5-59

NOTE:
The approach warning chime may sound
and the system display may blink when the
ICC sensor detects objects on the side of
the vehicle
Aor on the side of the roadA.
This may cause the ICC system to deceler-
ate or accelerate the vehicle. The ICC sen-
sor may detect these objects when the ve-
hicle is driven on winding roads, narrow
roads, hilly roads, or when entering or exit-
ing 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 conditions
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 (Drive) or
Manual mode
● When the parking brake is applied
● When the SNOW mode switch is turned on
● When the VDC system is turned off
● When ABS or VDC (including the TCS)
operates
● When the radar signal is temporarily inter-
rupted
● When distance measurement becomes im-
paired due to adhesion of dirt or obstruction
to the sensor area
● When a wheel slips

Action to take:
When the conditions listed above are no longer
present, turn the system off using the ICC
CRUISE ON/OFF switch. Turn the ICC system
back on to use the system.
Condition B:
When the sensor area of the front bumper is dirty
making it impossible to detect a vehicle ahead,
the ICC system is automatically canceled.
The chime sounds and the system warning light
(orange) will come on and the “Sensor Blocked”
indicator will appear.Action to take:
If the warning light comes on, 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 perform the settings
again.
Condition C:
When the ICC 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 set the ICC system again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the
system is malfunctioning. Although the ve-
hicle is still driveable under normal condi-
tions, have the vehicle checked at an
INFINITI retailer.

Sensor maintenance
The sensor for the ICC systemAis located
behind the front bumper.
To keep the ICC system operating properly, be
sure to observe the following:
● Always keep the sensor area of the front
bumper clean.
● Do not strike or damage the areas around
the sensor.
● Do not cover or attach stickers or similar
objects on the front bumper near the sensor
area. This could cause failure or malfunction. ●
Do not attach metallic objects near the sen-
sor area (brush guard, etc.) This could cause
failure or malfunction.
● Do not alter, remove, or paint the front bum-
per. Before customizing or restoring the
front bumper, please contact an INFINITI
retailer.
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
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.

DCA OPERATION
Always pay attention to the operation of the ve-
hicle and be ready to manually decelerate to
maintain the proper following distance. The DCA
system may not be able to decelerate the vehicle
under some circumstances.
The DCA system uses a sensor
Alocated be-
hind the front bumper of the vehicle to detect
vehicles traveling ahead. The sensor generally
detects the signals returned from the vehicle
ahead. Therefore, if the sensor cannot detect the
reflection from the vehicle ahead, the DCA sys-
tem may not operate. The following are some conditions in which the
sensor cannot detect the signals:
● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
detection
● 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 front
bumper area around the distance sensor is cov-
ered with dirt or is obstructed, the system will
automatically cancel. If the front bumper area of
the distance sensor is covered with ice, a trans-
parent or translucent vinyl bag, etc., the DCA
system may not detect them. In these instances,
the vehicle-to-vehicle distance control mode may
not cancel and may not be able to maintain the
selected following distance from the vehicle
ahead. Be sure to check and clean the front
bumper area around the distance sensor regu-
larly.
The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as nec-
essary and if the vehicle ahead comes to a stop,
