DISTANCE CONTROL MODE
LIMITATIONS
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
∙ The ICC system is primarily intended foruse on straight, dry, open roads with light
traffic. It is not advisable to use the ICC
system in city traffic or congested areas.
∙ The ICC system will not adapt automati- cally 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. ∙ As there is a performance limit to the dis-
tance control function, never rely solely
on the ICC system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain a safe distance between 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.
∙ Always pay attention to the operation of the vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(following distance) or selected vehicle
speed under some circumstances. ∙ 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, etc.
– 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
– Interference by other radar sources
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the ProPILOT Assist
system could result in serious injury or
death.
∙ ProPILOT Assist is not a self-driving sys-tem. Within the limits of its capabilities,
as described in this manual, it helps the
driver with certain driving activities.
∙ The ProPILOT Assist system is not a re- placement for proper driving procedures
and is not designed to correct careless,
inattentive or absent-minded driving.
ProPILOT Assist will not always steer
the vehicle to keep it in the lane. The Pro-
PILOT Assist system is not designed to
prevent loss of control. It is the driver’s
responsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.
∙ There are limitations to the ProPILOT Assist system capability. The ProPILOT
Assist system does not function in all
driving, traffic, weather, and road condi-
tions. It is the driver’s responsibility to
stay alert, drive safely, keep the vehicle in
the traveling lane, and be in control of the
vehicle at all times. ∙ The ProPILOT Assist system is only an
aid to assist the driver and is not a colli-
sion warning or avoidance device.
∙ The ProPILOT Assist system is for high- way use only and is not intended for city
driving. Failure to apply the brakes or
steer the vehicle when necessary may re-
sult in a serious accident.
∙ Always observe posted speed limits and do not set the speed over them.
∙ Never take your hands off the steering wheel when driving. Always keep your
hands on the steering wheel and drive
your vehicle safely.
∙ The ProPILOT Assist system does not re- act to stationary and slow moving
vehicles.
∙ Always drive carefully and attentively when using the ProPILOT Assist system.
Read and understand the Owner’s
Manual thoroughly before using the Pro-
PILOT Assist system. To avoid serious in-
jury or death, do not rely on the system to
prevent accidents or to control the vehi-
cle’s speed in emergency situations. Do
not use the ProPILOT Assist system ex-
cept in appropriate road and traffic
conditions. The ProPILOT Assist system is intended to
enhance the operation of the vehicle when
following a vehicle traveling in the same lane
and direction.
The ProPILOT Assist system uses a multi-
sensing front camera
Ainstalled behind the
windshield and a radar sensor located on the
front of the vehicle
Bto measure the dis-
tance to the vehicle ahead in the same lane
and to monitor the lane markers. If the vehicle
detects 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 will also help
keep the vehicle centered in the traveling lane
when clear lane markings are detected.

5-108Starting and driving

When passing another vehicle, the set speed
indicator
Bflashes when the vehicle speed
exceeds the set speed. The vehicle ahead
detection indicator turns off when the area
ahead of the vehicle is open. When the pedal
is released, the vehicle returns to the previ-
ously set speed. Even though your vehicle
speed is set in the ICC system, you can de-
press the accelerator pedal when it is neces-
sary to accelerate your vehicle rapidly.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system warns the driver with the chime and ICC sys-
tem display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
∙ The chime sounds.
∙ The vehicle ahead detection indicator and set distance indicator blink.
∙ You judge it necessary to maintain a safe distance.
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 increasing.
∙ When a vehicle cuts in near your vehicle.
The warning chime will not sound when: ∙ Your vehicle approaches other vehicles that are parked or moving slowly.
∙ The accelerator pedal is depressed, over- riding the system. NOTE:
The approach warning chime may sound and
the system display may flash when the radar
sensor detects objects on the side of the ve-
hicle or on the side of the road. This may
cause the ICC system to decelerate or accel-
erate the vehicle. The radar sensor may de-
tect these objects when the vehicle is driven
on winding, narrow, or hilly roads or when
the vehicle is entering or exiting a curve. In
these cases, you will have to manually con-
trol the proper distance ahead of your ve-
hicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
conditions (for example, if a vehicle is being
driven with some damage).

Blocked” warning message continues to be
displayed, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
Condition C
When driving on roads with limited road
structures or buildings (for example, long bridges, deserts, snow fields, driving next to
long walls), the system may illuminate the
system warning light and display the “Un-
available: Front Radar Blocked” message.
Action to take:
When the above driving conditions no longer
exist, turn the system back on.
ICC system malfunction
If the ICC system malfunctions, it will be
turned off automatically, a chime will sound,
and the speed control status warning (or-
ange) will illuminate.
Action to take:
If the warning light comes on, stop the vehicle
in a safe place. Turn the engine off, restart
the engine and set the ICC system again. If it
is not possible to set the ICC system or the
indicator stays on, it may be a malfunction.

∙ As there is a performance limit to the dis-tance control function, never rely solely
on the DCA system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain a safe distance between vehicles.
∙ Always pay attention to the operation of the vehicle and be ready to manually de-
celerate to maintain the proper following
distance. The DCA system may not be
able to decelerate the vehicle under some
circumstances.
∙ This system only brakes and moves the accelerator pedal upward to help assist
the driver to maintain a following dis-
tance from the vehicle ahead. Accelera-
tion should be operated by the driver.
∙ The DCA system does not control the ve- hicle speed or warn you when you ap-
proach stationary and slow moving ve-
hicles. You must pay attention to vehicle
operation to maintain proper distance
from vehicles ahead. ∙ The DCA system automatically deceler-
ates your vehicle to help assist the driver
to maintain a following distance from the
vehicle ahead. Manually brake when de-
celeration is required to maintain a safe
distance upon sudden braking by the ve-
hicle ahead or when a vehicle suddenly
appears in front of you. Always stay alert
when using the DCA system.
∙ If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill within
the limitations of the system. The system
will cancel with a warning chime once it
judges that the vehicle has come to a
standstill. To prevent the vehicle from
moving, the driver must depress the
brake pedal.
The DCA system is intended to assist the
driver in keeping a following distance from
the vehicle ahead traveling in the same lane
and direction.
If the radar sensor detects a slower moving
vehicle ahead, the system will reduce the ve-
hicle speed to help assist the driver to main-
tain a following distance.
The system automatically controls the
throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power) if
necessary. The detection range of the sensor is approxi-
mately 650 ft (200m) ahead.
Starting and driving5-139

Overriding the system:
The following driver’s operations override the
system operation:∙ When the driver depresses the accelera- tor pedal even further while the system is
moving the accelerator pedal upward,
the DCA system control of the accelera-
tor pedal is canceled.
∙ When the driver’s foot is on the accelera- tor pedal, the brake control by the system
is not operated.
∙ When the driver’s foot is on the brake pedal, neither the brake control nor the
alert by the system operates.
∙ When the ICC system is set, the DCA system will be canceled.Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and DCA
system display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
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 increasing
∙ 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 radar
sensor detects objects on the side of the
road. This may cause the DCA system to de-
celerate 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 manu-
ally control the proper distance ahead of
your vehicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
condition (for example, if a vehicle is being
driven with some damage).

tween vehicles because of frequent
acceleration or deceleration
– When towing a trailer or other vehicle
– Interference by other radar sources ∙ In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to con-
trol the distance from other vehicles us-
ing the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.
The radar 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
The following are some conditions in which
the sensor cannot detect the signals: ∙ When the snow or road spray from trav- eling vehicles reduces the sensor’s visibil-
ity
∙ When excessively heavy baggage is loaded in the rear seat or the luggage
room of your vehicle
