2020 INFINITI QX50 sensor

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 operation (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.SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
Under the following conditions, the DCA sys-
tem is automatically canceled. The chime will
sound and the DCA system switch indicator

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) the system may illuminate the sys-
tem warning light (orange) and display the
“Unavailable Front Radar Blocked” message.
Action to take:
When the above conditions no longer exist,
the DCA system will resume automatically.
Condition C:

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the RAB system
could result in serious injury or death.
∙ The RAB system is a supplemental aid tothe driver. It is not a replacement for
proper driving procedures. Always use
the side and rear mirrors and turn and
look in the direction you will move before
and while backing up. Never rely solely on
the RAB system. It is the driver’s respon-
sibility to stay alert, drive safely, and be
in control of the vehicle at all times.
∙ There is a limitation to the RAB system capability. The RAB system is not effec-
tive in all situations.
The RAB system can assist the driver when
the vehicle is backing up and approaching
objects directly behind the vehicle. The RAB system detects obstacles behind
the vehicle using the parking sensors
1lo-
cated on the rear bumper.
NOTE:
You can temporarily cancel the sonar func-
tion in the vehicle, but the RAB system will
continue to operate. For additional informa-
tion, please refer to “Front and rear sonar
system” in this section.

REAR AUTOMATIC BRAKING (RAB)
Starting and driving5-145

∙ When the vehicle approaches an obstaclewhile the accelerator or brake pedal is
depressed, the function may not operate
or the start of operation may be delayed.
The RAB system may not operate or may
not perform sufficiently due to vehicle
conditions, driving conditions, the traffic
environment, the weather, road surface
conditions, etc. Do not wait for the sys-
tem to operate. Operate the brake pedal
by yourself as soon as necessary.
∙ If it is necessary to override RAB opera- tion, strongly press the accelerator
pedal.
∙ Always check your surroundings and turn to check what is behind you before and
while backing up. The RAB system de-
tects stationary objects behind the ve-
hicle. The RAB system does not detect
the following objects:
– Moving objects
– Low objects
– Narrow objects
– Wedge-shaped objects
– Objects close to the bumper (less than approximately 1 ft [30 cm]) – Objects that suddenly appear
– Thin objects such as rope, wire, chain,
etc.
∙ The RAB system may not operate for the following obstacles:
– Obstacles located high off the ground
– Obstacles in a position offset from your vehicle
– Obstacles, such as spongy materials or snow, that have soft outer surfaces
and can easily absorb a sound wave
∙ The RAB system may not operate in the following conditions:
– There is rain, snow, ice, dirt, etc., at- tached to the sonar sensors.
– A loud sound is heard in the area around the vehicle.
– The surface of the obstacle is diagonal to the rear of the vehicle.
∙ The RAB system may unintentionally op- erate in the following conditions:
– There is overgrown grass in the area around the vehicle. – There is a structure (e.g., a wall, toll
gate equipment, a narrow tunnel, a
parking lot gate) near the side of the
vehicle.
– There are bumps, protrusions, or man- hole covers on the road surface.
– The vehicle drives through a draped flag or a curtain.
– There is an accumulation of snow or ice behind the vehicle.
– An ultrasonic wave source, such as an- other vehicle’s sonar, is near the
vehicle.
∙ Once the automatic brake control oper- ates, it does not operate again if the ve-
hicle approaches the same obstacle.
∙ The automatic brake control can only op- erate for a short period of time. There-
fore, the driver must depress the brake
pedal.
∙ In the following situations, the RAB sys- tem may not operate properly or may not
function sufficiently:
– The vehicle is driven in bad weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep hill.
5-148Starting and driving

– The vehicle’s posture is changed (e.g.,when driving over a bump).
– The vehicle is driven on a slippery road.
– The vehicle is turned sharply by turn- ing the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than INFINITI recommended are used.
– The brakes are cold at low ambient temperatures or immediately after
driving has started.
– The braking force becomes poor due to wet brakes after driving through a
puddle or washing the vehicle.
∙ Turn the RAB system off in the following conditions to prevent the occurrence of
an unexpected accident resulting from
sudden system operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed truck.
– The vehicle is on the chassis dynamometer.
– The vehicle drives on an uneven road surface. –Suspension parts other than those des-
ignated as Genuine INFINITI parts are
used. (If the vehicle height or the vehicle
body inclination is changed, the system
may not detect an obstacle correctly.)
∙ Excessive noise (e.g., audio system vol-
ume, an open vehicle window) will inter-
fere with the chime sound, and it may not
be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “System
fault” warning message will appear in the
vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB system
checked. It is recommended that you visit an
INFINITI retailer for this service.
NOTE:
If the RAB system cannot be operated tem-
porarily, the RAB system warning light
blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure proper
operation of the system:
∙ Always keep the parking sensors
1
clean.
∙ If the parking sensors are dirty, wipe them off with a soft cloth while being
careful to not damage them.
LSD3559
Starting and driving5-149

∙ Do not subject the area around the park-ing sensors
1to strong impact. Also, do
not remove or disassemble the parking
sensors. If the parking sensors and pe-
ripheral areas are deformed in an acci-
dent, etc., have the sensors checked. It is
recommended that you visit an INFINITI
retailer for this service.
∙ Do not install any stickers (including transparent stickers) or accessories on
the parking sensors
1and their sur-
rounding areas. This may cause a mal-
function 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
Alocated 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
Binstalled 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 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.
