2020 INFINITI QX50 warning light

1. Vehicle ahead detection indicator
2. FEB with Pedestrian Detection emer-gency warning indicator
3. FEB with Pedestrian Detection system warning light
SYSTEM OPERATION
The FEB with Pedestrian Detection system
operates at speeds above approximately
3 mph (5 km/h). For the pedestrian detection
function, the FEB with Pedestrian Detection
system operates at speeds between 6 –
37 mph (10 – 60 km/h).
If a risk of a forward collision with a vehicle is
detected, the FEB with Pedestrian Detection
system will first provide a warning to the
driver by flashing the vehicle ahead detection
indicator and providing an audible alert. In
addition, the FEB with Pedestrian Detection
system pushes the accelerator pedal up, and
then the system applies partial braking. If the
driver applies the brakes quickly and force-
fully, but the FEB with Pedestrian Detection
system detects that there is still the possibility
of a forward collision, the system will auto-
matically increase the braking force.

If the risk of a collision becomes imminent
and the driver does not take action, the FEB
with Pedestrian Detection system issues the
second warning to the driver by flashing the
FEB with Pedestrian Detection emergency
warning indicator (red), providing an audible
warning, and then automatically applies
harder braking.
If a risk of a forward impact with a pedestrian
is detected, the FEB with Pedestrian Detec-
tion system will provide a warning to the
driver by flashing the FEB with Pedestrian
Detection emergency warning indicator (red),
provides an audible alert and the system will
apply partial baking. If the driver applies the
brakes quickly and forcefully but the FEB
with Pedestrian Detection system detects
that there is still the possibility of a forward
impact with a pedestrian, the system will au-
tomatically increase the braking force. If the
risk of collision becomes imminent and the
driver does not take action, the FEB with
Pedestrian Detection system automatically
applies harder braking.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 pedestrian 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 accordance
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 vehicle’s path, the FEB with Pedestrian Detec-
tion system will not function when the
vehicle is driven at speeds over ap-
proximately 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 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.
– The camera area of the windshield is fogged 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.
5-154Starting and driving

– 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 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.
