2020 NISSAN SENTRA parking sensors

RCTA SYSTEM LIMITATIONSWARNING
Listed below are the system limitations
for the RCTA system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death. •
Always check surroundings and turn
to check what is behind you before
backing up. The radar sensors detect
approaching (moving) vehicles. The
radar sensors cannot detect every
object such as:
– Pedestrians, bicycles, motor-
cycles, animals or child-operated
toy vehicles
– A vehicle that is passing at speeds
greater than approximately 19
mph (30 km/h)
– A vehicle that is passing at speeds
lower than approximately 5 mph
(8 km/h)
• The radar sensors may not detect
approaching vehicles in certain situ-
ations:
– Illustration
OA: When a vehicle
parked next to you obstructs the
beam of the radar sensor.
– Illustration
OB: When the vehicle is
parked in an angled parking
space.
– Illustration
OC: When the vehicle is
parked on inclined ground.
– Illustration
OD: When an ap-
proaching vehicle turns into your
vehicle's parking lot aisle.

Failure to follow the warnings and in-
structions for proper use of the RAB
system could result in serious injury or
death.
• The RAB system is a supplemental
aid to the driver. It is not a replace-
ment 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 sys-
tem. It is the driver’s responsibility to
stay alert, drive safely, and be in con-
trol of the vehicle at all times.
• There is a limitation to the RAB sys-
tem capability. The RAB system is not
effective 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
O1
located on the rear bumper.
NOTE:
You can temporarily cancel the sonar
function in the vehicle, but the RAB sys-
tem will continue to operate. For addi-
tional information, please refer to “Rear
Sonar System (RSS)” in this section.

–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 materi-
als or snow, that have sof t 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.,
attached to the sonar sensors.
– A loud sound is heard in the area
around the vehicle.
– The surface of the obstacle is di-
agonal to the rear of the vehicle.
• The RAB system may unintentionally
operate 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
manhole 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
another vehicle’s sonar, is near
the vehicle.
• Once the automatic brake control
operates, it does not operate again if
the vehicle approaches the same
obstacle.
• The automatic brake control can only
operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
• In the following situations, the RAB
system 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. –
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
turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN
recommended are used.
– The brakes are cold at low ambi-
ent temperatures or immediately
af ter driving has started.
– The braking force becomes poor
due to wet brakes af ter driving
through a puddle or washing the
vehicle.
• Turn the RAB system off in the follow-
ing conditions to prevent the occur-
rence of an unexpected accident re-
sulting 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 designated as Genuine
NISSAN parts are used. (If the ve-
hicle height or the vehicle body in-
clination is changed, the system
may not detect an obstacle
correctly.)
• Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere 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 “Sys-
tem 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 sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure
proper operation of the system:
• Always keep the parking sensors
O1
clean.
• If the parking sensors are dirty, wipe them off with a sof t cloth while being careful to
not damage them.
LSD3754
5-80Starting and driving

• Do not subject the area around the park-ing sensors
O1to 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 a NISSAN
dealer for this service.
• Do not install any stickers (including transparent stickers) or accessories on
the parking sensors
O1and their sur-
rounding areas. This may cause a mal-
function or improper operation.
WARNING
Failure to follow the warnings and in-
structions for proper use of the AEB
with Pedestrian Detection system
could result in serious injury or death.
• The AEB with Pedestrian Detection
system is a supplemental aid to the
driver. It is not a replacement for the
driver’s attention to traffic condi-
tions or responsibility to drive safely.
It cannot prevent accidents due to
carelessness or dangerous driving
techniques.
• The AEB with Pedestrian Detection
system does not function in all driv-
ing, traffic, weather and road
conditions.
The AEB 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 AEB with Pedestrian Detection system
uses a radar sensor located on the front of
the vehicle
OBto measure the distance to
the vehicle ahead in the same lane. For
pedestrians, the AEB with Pedestrian De-
tection system uses a camera installed be-
hind the windshield
OAin addition to the
radar sensor.

Listed below are the system limitations
for the sonar system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death. •
Read and understand the limitations
of the sonar system as contained in
this section. Inclement weather may
affect the function of the sonar sys-
tem; this may include reduced per-
formance or a false activation.
• The system is deactivated at speeds
above 6 mph (10 km/h). It is reacti-
vated at lower speeds.
• Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may af-
fect the function of the system; this
may include reduced performance or
a false activation.
• The system is not designed to pre-
vent contact with small or moving
objects. Always move slowly. The
system will not detect small objects
below the bumper or on the ground.
• The system may not detect the fol-
lowing objects: fluff y objects such as
