2-28Instruments and controls

–Oncoming vehicles.
– Vehicles remaining in the detection
zone when you accelerate from a
stop. For additional information, see
“BSI driving situations” (P. 5-60).
– A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle. For additional
information, see “BSI driving situa-
tions” (P. 5-60).
– A vehicle approaching rapidly from
behind. For additional information,
see “BSI driving situations” (P. 5-60).
– A vehicle which your vehicle over-
takes rapidly. For additional infor-
mation, see “BSI driving situations”
(P. 5-60).
– A vehicle that passes through the de-
tection zone quickly.
– When overtaking several vehicles in a
row, the vehicles after the first ve-
hicle may not be detected if they are
traveling close together. •
The radar sensors’ detection zone is de-
signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an ad-
jacent lane. When driving in a narrow
lane, the radar sensors may detect ve-
hicles driving two lanes away.
• The radar sensors are designed to ignore
most stationary objects; however, ob-
jects such as guardrails, walls, foliage
and parked vehicles may occasionally be
detected. This is a normal driving
condition.
• The following conditions may reduce the
ability of the radar to detect other ve-
hicles:
– Severe weather
– Road spray
– Ice/frost/dirt build-up on the vehicle
• Do not attach stickers (including trans-
parent material), install accessories or
apply additional paint near the radar
sensors. These conditions may reduce
the ability of the radar to detect other
vehicles.
• The camera may not detect lane markers
in the following situations and the BSI
system may not operate properly: –
On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-
standard lane markers; lane markers
covered with water, dirt, snow, etc.
– On roads where discontinued lane
markers are still detectable.
– On roads where there are sharp
curves.
– On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts, seams
or lines remaining after road repairs.
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direction
does not align with the lane markers.
– When traveling close to the vehicle in
front of you, which obstructs the lane
camera unit detection range.
– When rain, snow or dirt adheres to
the windshield in front of a lane cam-
era unit.
– When the headlights are not bright
due to dirt on the lens or if aiming is
not adjusted properly.
Starting and driving5-59

•Always drive carefully and attentively
when using the ProPILOT Assist system.
Read and understand the Owner’s
Manual thoroughly before using the
ProPILOT Assist system. To avoid seri-
ous injury or death, do not rely on the
system to prevent accidents or to control
the vehicle’s speed in emergency situa-
tions. Do not use the ProPILOT Assist
system except 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 cameraOAinstalled behind the
windshield and a radar sensor located on the
front of the vehicle
OBto 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.

5-78Starting and driving

–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
towing a trailer. The system may not de-
tect a vehicle ahead.
• In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert
and avoid using the ICC system where
not recommended in this warning
section.
The ICC system will not detect the following
objects:
• Stationary or 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 radar sensor cannot properly detect a
vehicle ahead and the system may not oper-
ate properly: • When the sensor detection is reduced (con-
ditions such as rain, snow, fog, dust storms,
sandstorms, and road spray from other
vehicles)
• Driving on a steep downhill slope or roads with sharp curves
• Driving on a bumpy road surface, such as an uneven dirt road
• If dirt, ice, snow or other material is cover- ing the radar sensor area
• A complicated-shaped vehicle such as a car carrier trailer or flatbed truck/trailer is near
the vehicle ahead.
• Interference by other radar sources
• When your vehicle is towing a trailer, etc.
• When excessively heavy baggage is loaded in the rear seat or cargo area of your
vehicle.
The ICC system is designed to automatically
check the radar sensor’s operation within the
limitations of the system.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the detec-
tion zone for the ICC system to maintain the
selected distance from the vehicle ahead. A
vehicle ahead may move outside of the de-
tection 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 center line of the
lane. A vehicle that is entering 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.
The ICC system (with ProPILOT Assist) uses
a multi-sensing front camera. The following
are some conditions in which the camera may
not properly detect a vehicle and detection of
a vehicle ahead may be delayed:
• Poor visibility (conditions such as rain,
snow, fog, dust storms, sandstorms, and
road spray from other vehicles)
• The camera area of the windshield is fogged up or covered with dirt, water
drops, ice, snow, etc.
• Strong light (for example, sunlight or high beams from oncoming vehicles) enters the
front camera
• A sudden change in brightness occurs (for example, when the vehicle enters or exits a
tunnel or shaded area or lightning flashes)
Starting and driving5-93

Action to take:
When the conditions listed above are no lon-
ger present, turn the system off using the
ProPILOT Assist switch. Turn the ProPILOT
Assist system back on to use the system.
NOTE:
When the ICC system is canceled under
the following conditions at a standstill,
the electronic parking brake is automati-
cally activated:
• Any door is open.
• The driver’s seat belt is not fastened.
• Your vehicle has been stopped by the ICCsystem for approximately 3 minutes or
longer.
• The shift lever is not in the D (Drive) posi- tion or manual shift mode.
• The VDC system is turned off.
• When distance measurement becomes im- paired due to adhesion of dirt or obstruc-
tion to the sensor.
• When the radar signal is temporarily interrupted.
Condition B
When the radar sensor of the front bumper is
covered with dirt or is obstructed, the ICC
system will automatically be canceled. The chime will sound and the “Unavailable:
Front Radar Blocked” warning message will
appear in the vehicle information display.
Action to take:
If the warning message appears, stop the
vehicle in a safe place, press the Park button
to place the vehicle in the P (Park) position,
and turn the engine off. When the radar sig-
nal is temporarily interrupted, clean the sen-
sor area of the front bumper and restart the
engine. If the “Unavailable: Front Radar
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.
Although the normal driving can be contin-
ued, the ICC system should be inspected. It is
recommended that you visit an INFINITI re-
tailer for this service.
ICC sensor maintenance
The radar sensor is located on the front of the
vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
• Always keep the sensor area clean.
• Do not strike or damage the areas around
the sensor.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the sensor. This could cause failure or
malfunction.
5-96Starting and driving

•As there is a performance limit to the
distance control function, never rely
solely on the DCA 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, depending
on the distance to the vehicle ahead and
the surrounding circumstances in order
to maintain 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 follow-
ing 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
deceleration is required to maintain a
safe distance upon sudden braking by
the vehicle ahead or when a vehicle sud-
denly 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 driving5-107

•The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the DCA 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.
– On off-road surfaces such as on sand
or rock, etc.
– During bad weather (rain, fog, snow,
etc.)
– When rain, snow or dirt adhere to the
sensor area of the front bumper
– On steep downhill roads (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
– 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
control the distance from other vehicles
using 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 travel- ing vehicles reduces the sensor’s visibility
• When excessively heavy baggage is loaded in the rear seat or the luggage room of your
vehicle
Starting and driving5-113

For additional information about the VDC
system, see “Vehicle Dynamic Control
(VDC) system” (P. 5-154).
• When ABS or VDC (including the TCS) is operating
• When the radar signal is temporarily interrupted
Action to take:
When the conditions listed above are no lon-
ger present, turn the system off with ProPI-
LOT Assist switch on the steering wheel.
Turn the DCA system back on to use the
system.
Condition B:
When the radar sensor area is covered with
dirt or is obstructed, making it impossible to
detect a vehicle ahead, the DCA system is
automatically canceled.
The chime sounds and the DCA system
warning light (orange) will come on and the
“Unavailable: Front Radar Blocked” warning
will appear.
Action to take:
If the warning light comes on, park the vehicle
in a safe place, press the park button to place
the vehicle in the P (Park) position and turn
the engine off. When the radar signal is tem-porarily interrupted, clean the sensor area
and restart the engine. If the “Unavailable:
Front Radar Blocked” warning continues to
be displayed, have the DCA system checked.
It is recommended you visit and INFINITI
retailer for this service.
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 sys-
tem warning light (orange) and display the
“Unavailable Front Radar Blocked” message.
Action to take:
When the above conditions no longer exist,
the DCA system will resume automatically.
Condition C:
When the DCA system is not operating prop-
erly, the chime sounds, the DCA system
warning light (orange) and the system “Mal-
function” warning message will appear in the
vehicle information display.
Action to take:
If the DCA system warning light (orange) and
the warning message appear, stop the ve-
hicle in a safe place and place the vehicle in
the P (Park) position. Turn the engine off,
restart the engine, and turn on the DCA sys-
tem again.

This may cause a malfunction or improper
operation.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the FEB with Pedes-
trian Detection system could result in seri-
ous injury or death.
• The FEB with Pedestrian Detection sys-
tem is a supplemental aid to the driver. It
is not a replacement for the driver’s at-
tention to traffic conditions or responsi-
bility to drive safely. It cannot prevent
accidents due to carelessness or danger-
ous driving techniques.
• The FEB with Pedestrian Detection sys-
tem does not function in all driving, traf-
fic, weather and road conditions.
The FEB with Pedestrian Detection system
can assist the driver when there is a risk of a
forward collision with the vehicle ahead in the
traveling lane or with a pedestrian ahead in
the traveling lane. The FEB with Pedestrian Detection system
uses a radar sensor
OAlocated on the front of
the vehicle to measure the distance to the
vehicle ahead in the same lane. For pedestri-
ans, the FEB with Pedestrian Detection sys-
tem uses a camera
OBinstalled behind the
windshield in addition to the radar sensor.

following objects:
– Small pedestrians (including small
children), animals and cyclists.
– Pedestrians in wheelchairs or using
mobile transport such as scooters,
child-operated toys, or skateboards.
– Pedestrians who are seated or other-
wise not in a full upright standing or
walking position.
– Oncoming vehicles
– Crossing vehicles
– Obstacles on the roadside •
The FEB with Pedestrian Detection sys-
tem has some performance limitations.
– If a stationary vehicle is in the vehi-
cle’s path, the FEB with Pedestrian
Detection system will not function
when the vehicle is driven at speeds
over approximately 50 mph (80
km/h).
– For pedestrian detection, the FEB
with Pedestrian Detection system
will not function when the vehicle is
driven at speeds over approximately
37 mph (60 km/h) or below approxi-
mately 6 mph (10km/h).
• The FEB with Pedestrian Detection sys-
tem will not function for pedestrians in
darkness or in tunnels, even if there is
street lighting in the area.
• For pedestrians, the FEB with Pedes-
trian Detection system will not issue the
first warning.
• The FEB with Pedestrian Detection sys-
tem may not function if the vehicle ahead
is narrow (for example, a motorcycle).
• The FEB with Pedestrian Detection sys-
tem may not function if speed difference
between the two vehicles is too small. •
The radar sensor FEB with Pedestrian
