When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the sensor may
detect vehicles in a different lane, or may
temporarily not detect a vehicle traveling
ahead. This may cause the system to work
inappropriately.
The detection of vehicles may also be af-
fected by vehicle operation (steering maneu-
ver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the system may warn you by
blinking the system indicator and sounding
the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.
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.

Starting and driving5-107
NOTE:
The approach warning chime may sound and
the system display may blink when ICC sen-
sor detects vehicles in other lanes
Aor ob-
jects on the side of the road
A. This may
cause the DCA system to operate inappro-
priately. The ICC sensor may detect these
objects when the vehicle is driven on winding
roads, narrow roads, hilly roads or when en-
tering or exiting a curve. In these cases you
will have to manually control the proper dis-
tance 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).
SYSTEM TEMPORARILY
UNAVAILABLE
Under the following conditions, the DCA sys-
tem will not operate and the DCA cancella-
tion message will pop up:
∙ When the SNOW mode switch is se- lected by using the INFINITI Drive Mode
Selector (To use the DCA system, turn off
the SNOW mode, then turn on the dy-
namic driver assistance switch.)
For additional information about the
SNOW mode switch, refer to “Snow
mode” in this section.

5-108Starting and driving
Condition B:
When the sensor area of the front bumper is
dirty, making it impossible to detect a vehicle
ahead, the DCA system is automatically can-
celed.
The chime sounds and the system warning
light (orange) will come on and the “Unavail-
able: Front Radar Obstruction” indicator will
appear.
Action to take:
If the warning light comes on, park the vehicle
in a safe place, turn the engine off. Clean the
sensor area of the bumper and then perform
the settings again.Condition C:
When the DCA system is not operating prop-
erly, the chime sounds and the system warn-
ing light (“DCA” 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, and turn on the DCA 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 drivable under normal conditions,
have the vehicle checked. It is recommended
that you visit an INFINITI retailer for this
service.
SYSTEM MAINTENANCE
The sensor for the DCA system is common
with ICC and is located behind the front bum-
per.

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. The FEB with Pedestrian Detection system
uses a radar sensor
Alocated behind the
lower grille of the front bumper to measure
the distance to the vehicle ahead in the same
lane. For pedestrians, the FEB with Pedes-
trian Detection system uses a camera
Bin-
stalled 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 vehicle’s path, the FEB with Pedestrian Detec-
tion system will not function when the
vehicle is driven at speeds over ap-
proximately 80 km/h (50 mph).
– For pedestrian detection, the FEB with Pedestrian Detection system will
not function when the vehicle is driven
at speeds over approximately
60 km/h (37 mph) or below approxi-
mately 10 km/h (6 mph).
∙ 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 Pedestrian
Detection system will not issue the first
warning and will not push the accelerator
pedal up.
∙ 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 Detection system may not function prop-
erly or detect a vehicle ahead in the fol-
lowing conditions:
– Poor visibility (conditions 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 covering the radar sensor area.
– Interference by other radar sources.
5-116Starting and driving
– The camera area of windshield isfogged 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. Strong light
causes the area around the pedestrian
to be cast in a shadow, making it diffi-
cult to see.
– A sudden change in brightness occurs. (For example, when the vehicle enters
or exits a tunnel or a shaded area or
lightning flashes.)
– The poor contrast of a person to the background, such as having clothing
color or pattern which is similar to the
background.
– The pedestrian’s profile is partially obscured or unidentifiable due to the
pedestrian transporting luggage,
wearing bulky or very loose-fitting
clothing or accessories.
∙ The system performance may degrade in the following conditions:
– The vehicle is driven on a slippery road.
– The vehicle is driven on a slope. – Excessively heavy baggage is loaded
in the rear seat or the trunk room of
your vehicle.
∙ The system is designed to automatically check the sensors’ (radar and camera)
functionality, within certain limitations.
The system may not detect blockage of
sensor areas covered by ice, snow or
stickers, for example. In these cases, the
system may not be able to warn the
driver properly. Be sure that you check,
clean and clear sensor areas regularly.
∙ In some road and traffic conditions, the FEB with Pedestrian Detection system
may unexpectedly apply partial braking.
When acceleration is necessary, depress
