2021 INFINITI Q60 COUPE sensor

5-96Starting and driving
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle or if another vehicle cuts in, the
system warns the driver with the chime and
DCA system display. Decelerate by depres-
sing the brake pedal to maintain a safe
vehicle distance if:
.The chime sounds.
.The vehicle ahead detection indicator
blinks.
.The driver assist system forward indica-
tor (orange) blinks.
The warning chime may not sound in some
cases when there is a short distance be-
tween 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 driver assist system forward indicator
(orange) blinks and the warning chime will
not sound when your vehicle approaches
vehicles that are parked or moving slowly.
NOTE:
The approach warning chime may soundand the driver assist system forward in-
dicator (orange) may blink when the radar
sensor detects objects on the side of the
vehicle or on the side of the road. This may
cause the DCA system to decelerate 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
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).

front of you.
DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
of the DCA system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.This system will not adapt automati-
cally to road conditions. Do not use
the system on roads with sharp
curves, or on icy roads, in heavy rain
or in fog.
.The DCA system will not apply brake
control while the driver’s foot is on
the accelerator pedal.
.As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive 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 surround-
ing circumstances in order to main-
tain a safe distance between vehicles..The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the DCA system
under the following conditions:
— On roads with 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 system sensor
— On steep downhill roads (fre-
quent braking may result in over-
heating the brakes)
— On repeated uphill and downhill
roads
.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 accel-
erator 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 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
The following are some conditions in which
the sensor cannot detect the signals:
.When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
.When excessively heavy baggage is
loaded in the rear seat or the trunk of
your vehicle

The detection zone of the sensor is limited. A
vehicle ahead must be in the detection zone
for the system to operate.
A vehicle ahead may move outside of the
detection 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 entering the lane ahead
may not be detected until the vehicle has
completely moved into the lane.If this
occurs, the system may warn you by blink-
ing the system indicator and sounding the
chime. The driver may have to manually
control the proper distance away from
vehicle traveling ahead.

SSD0253
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 travel-
ing ahead. This may cause the system to
work inappropriately.
The detection of vehicles may also be
affected by vehicle operation (steering man-
euver 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 unexpect-
edly. You will have to manually control the
proper distance away from the vehicle
traveling ahead.

using mobile transport such as
scooters, child-operated toys, or
skateboards.
— Pedestrians who are seated or
otherwise not in a full upright
standing or walking position.
— Oncoming vehicles— Crossing vehicles
— Obstacles on the roadside
.The FEB with pedestrian detection
system has some performance limita-
tions.
— If a stationary vehicle is in the
vehicle’s path, the FEB with pe-
destrian 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 approximately 6
MPH (10km/h).
.The FEB with pedestrian detection
system will not function for pedes-
trians 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 and will not push
the accelerator pedal up.
.The FEB with pedestrian detection
system may not function if the vehi-
cle ahead is narrow (for example amotorcycle).
.The FEB with pedestrian detection
system may not function if speed
difference between the two vehicles
is too small.
.The radar sensor FEB with pedes-
trian detection system may not func-
tion properly or detect a vehicle
ahead in the following conditions:
— Poor visibility (conditions such as
rain, snow, fog, dust storms,
sandstorms, and road spray from
other vehicles)

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 par-
tially obscured or unidentifiable
due to the pedestrian transport-
ing luggage, wearing bulky or very
loose-fitting clothing or acces-
sories.
.The system performance may de-
grade 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 of your vehicle.
.The system is designed to automati-
cally check the sensor (radar and
camera)’s functionality, within cer-
tain limitations. The system may not
detect blockage of sensor areas cov-ered 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 par-
tial braking. When acceleration is
necessary, depress the accelerator
pedal to override the system.
.The FEB with pedestrian detection
system may operate when the fol-
lowing are similar to the outlines of
vehicles or pedestrians, or if they are
the same size and position as a
vehicle’s tail lights.
— Paint or a pattern on the road or
a wall (including faded and unu-
sual road markings).
— A shape formed by road struc-
tures ahead (such as tunnels,
viaducts, traffic signs, reflectors
installed on the side of vehicles,
reflection sheets, and guardrails).
.The FEB with pedestrian detection
system may react to:
— Obstacles on the roadside (traffic
sign, guardrail, pedestrian, vehi-
cle, etc.)
— Obstacles above road (low
bridge, traffic sign, etc.)
