2021 INFINITI QX50 Front Radar

• Do not install any stickers (including trans-parent stickers) or accessories on the park-
ing sensors
O1and their surrounding areas.
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.

FEB WITH PEDESTRIAN
DETECTION SYSTEM
LIMITATIONS
WARNING
Listed below are the system limitations for
the FEB with Pedestrian Detection system.
Failure to operate the vehicle in accor-
dance with these system limitations could
result in serious injury or death.
• The FEB with Pedestrian Detection sys-
tem cannot detect all vehicles or pedes-
trians under all conditions.
• The radar sensor FEB with Pedestrian
Detection system does not detect the
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
Detection system may not function
properly or detect a vehicle ahead in the
following conditions:
– Poor visibility (conditions such as
rain, snow, fog, dust storms, sand-
storms, 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.
– The camera area of the windshield is
fogged up, or covered with dirt, wa-
ter 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 pedes-
trian to be cast in a shadow, making it
difficult 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.)

SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
In the following conditions, the FEB with Pe-
destrian Detection system warning light
blinks and the system will be turned off
automatically.
• The radar sensor picks up interference fromanother radar source.
• The camera area of the windshield is misted or frozen.
• Strong light is shining from the front.
• The cabin temperature is over approxi- mately 104°F (40°C) in direct sunlight.
• The camera area of the windshield glass is continuously covered with dirt, etc.
Action to take
When the above conditions no longer exist,
the FEB with Pedestrian Detection system
will resume automatically.
NOTE:
When the inside of the windshield or camera
area is misted or frozen, it will take a period
of time to remove it after A/C turns ON. If
dirt appears on this area have it checked. It is
recommended that you visit an INFINITI re-
tailer for this service.

Condition B:
In the following conditions, the FEB with Pe-
destrian Detection system warning light will
illuminate, the system will be turned off au-
tomatically and the “Unavailable: Front Radar
Blocked” warning message will appear in the
vehicle information display.
• The sensor area of the front bumper iscovered with dirt or is obstructed.
Action to take
If the warning light (orange) comes on, stop
the vehicle in a safe place, place the shift lever
in the P (Park) position and turn the engine
off. Clean the radar sensor area of the front
bumper or the camera area of the windshield
with a soft cloth, and restart the engine. If the
warning light continues to illuminate, have
the FEB with Pedestrian Detection system
checked. It is recommended that you visit an
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).
Action to take
When the above conditions no longer exist,
the FEB with pedestrian detection system
will resume automatically.NOTE:
If the FEB with Pedestrian Detection system
stops working, the PFCW system (if so
equipped) will also stop working.
SYSTEM MALFUNCTION
If the FEB with Pedestrian Detection system
malfunctions, it will be turned off automati-
cally, a chime will sound, the FEB with Pedes-
trian Detection system warning light (orange)
will illuminate and the warning message
[Malfunction] will appear in the vehicle infor-
mation display.
Action to take
If the warning light (orange) comes on, stop
the vehicle in a safe location, turn the engine
off and restart the engine. If the warning light
continues to illuminate, have the FEB with
Pedestrian Detection system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
NOTE:
If the FEB with Pedestrian Detection system
stops working, the PFCW system (if so
equipped) will also stop working.

SYSTEM MAINTENANCE
The radar sensorOAis located on the front of
the vehicle. The camera
OBis located on the
upper side of the windshield.
To keep the FEB with Pedestrian Detection
system operating properly, be sure to ob-
serve the following:
• Always keep sensor areas of the front bumper and windshield clean.
• Do not strike or damage the areas around the sensors (ex. Bumper, windshield). • Do not cover or attach stickers, or install
any accessory near the sensors. This could
block sensor signals, and/or cause failure
or malfunction.
• Do not attach metallic objects near the ra- dar sensor (brush guard, etc.). This could
cause failure or malfunction.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit's detection
capability.
• Do not alter, remove or paint the front bumper. Before customizing or restoring
the front bumper, it is recommended that
you visit an INFINITI retailer.Radio frequency statement

Failure to follow the warnings and instruc-
tions for proper use of the PFCW system
could result in serious injury or death.
• The PFCW system can help warn the
driver before a collision occurs but will
not avoid a collision. It is the driver’s re-
sponsibility to stay alert, drive safely and
be in control of the vehicle at all times.
The PFCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle ahead
in the same lane.
The PFCW system uses a radar sensor
OAlocated on the front of the vehicle to measure
the distance to the vehicle ahead in the same
lane.
