2023 INFINITI QX80 sensor

5-100Starting and driving
— When the vehicle or pedestrian isoffset from the vehicle’s forward
path.
— If the speed difference between the two vehicles is small.
— The pedestrian’s profile is par- tially obscured or unidentifiable;
for example, due to transporting
luggage, pushing a stroller, wear-
ing bulky or very loose-fitting
clothing or accessories, or being
in a unique posture (such as rais-
ing hands).
— There is poor contrast of a person to the background, such as having
clothing color or pattern which is
similar to the background.
— For approximately 15 seconds after starting the engine
— If the vehicle ahead has a unique or unusual shape, extremely low
or high clearance heights, or unu-
sual cargo loading or is narrow
(for example, a motorcycle).
— When the vehicle or pedestrian is located near a traffic sign, a
reflective area (for example,
water on road), or is in a shadow. — When multiple pedestrians are
grouped together.
— When the view of the pedestrian is obscured by a vehicle or other
object.
— While towing a trailer or other vehicle.
. The system performance may be
degraded 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
cargo area 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 some forms of obstruction of
the sensor area such as 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 a pattern,
object, shadow or lights are detected
that are similar to the outline of
vehicles or pedestrians, or if they
are the same size and position as a
vehicle or motorcycle’s tail lights.
. The system may keep operating when
the vehicle ahead is turning right or
left.
. The system may operate when your
vehicle is approaching and passing a
vehicle ahead.
. Depending on the road shape (curved
road, entrance and exit of the curve,
winding road, lane regulation, under
construction, etc.), the system may
operate temporarily for the oncoming
vehicle in front of your vehicle.

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction or on a slope,
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
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.SYSTEM TEMPORARILY UNA-

.The sonar system is designed as an
aid to the driver in detecting large
stationary objects to help avoid da-
maging the vehicle.
. The sonar system is not designed to
prevent contact with small or moving
objects. Always move slowly. The
system will not detect small objects
below the bumper, and may not
detect objects close to the bumper
or on the ground.
. The sonar system may not detect the
following objects: fluffy objects such
as snow, cloth, cotton, glass-wool,
etc.; thin objects such as rope, wire
and chain, etc.; or wedge-shaped
objects.
. The front and rear sonar sensors
detect the distance between the
vehicle and the obstacle by detecting
the sound wave reflected from the
surface of an obstacle. When there is
a sound such as horn, or an ultrasonic
source (such as sonar of other vehi-
cles) around the vehicle, the sonar
sensors may not detect objects prop-
erly.
If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or bent,
the sensing zone may be altered causing inaccurate measurement of obstacles or
false alarms.
CAUTION
.
Excessive noise (such as audio system
volume or an open vehicle window)
will interfere with the tone and it may
not be heard.
. Keep the sonar sensors (located on
the bumper fascia) free from snow,
ice and large accumulations of dirt.
Do not clean the sonar sensors with
sharp objects. If the sensors are
covered, the accuracy of the sonar
function will be diminished.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever
is in the D (Drive) position and both front and
rear obstacles when the shift lever is in the R
(Reverse) position.
Sonar Operation Table
WAF0775X
The system is deactivated at speeds above 6
MPH (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after 3
seconds when an obstacle is detected by
only the corner sensor and the distance does
not change. The tone will stop when the
obstacle get away from the vehicle.
When the object is detected, the indicator
(green) appears and blinks and the tone
sounds intermittently. When the vehicle
moves closer to the object, the color of the
indicator turns yellow and the rate of the
blinking increases. When the vehicle is very
close to the object, the indicator stops
blinking and turns red, and the tone sounds
