Infiniti QX50 (2021 year). Manual in english — page 23

While the FEB with Pedestrian Detection
system is operating, you may hear the sound
of brake operation. This is normal and indi-
cates that the FEB with Pedestrian Detection
system is operating properly.

NOTE:

The vehicle’s brake lights come on when any
braking is performed by the FEB with Pedes-
trian Detection system.

Depending on vehicle speed and distance to
the vehicle or pedestrian ahead, as well as
driving and roadway conditions, the system
may help the driver avoid a forward collision
or may help mitigate the consequences if a
collision should be unavoidable. If the driver is
handling the steering wheel, accelerating or
braking, the FEB with Pedestrian Detection
system will function later or will not function.

The automatic braking will cease under the
following conditions:
• When the steering wheel is turned to avoid

a collision.

• When the accelerator pedal is depressed.
• When there is no longer a vehicle or a pe-

destrian detected ahead.

If the FEB with Pedestrian Detection system
has stopped the vehicle, the vehicle will re-
main at a standstill for approximately 2 sec-
onds before the brakes are released.

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.)

Starting and driving

5-127

–

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 sensor’s (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
the accelerator pedal to override the
system.

•

Excessive noise will interfere with the
warning chime sound, and the chime may
not be heard.

5-128

Starting and driving

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 operating (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 indica-
tor and sounding the chime unexpectedly.
You will have to manually control the proper
distance away from the vehicle traveling
ahead.
