2020 NISSAN MAXIMA sensor

1. Side BSW/RCTA Indicator Light
2. BSW/RCTA Indicator
BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 mph (32km/h).
If the radar sensors detect a vehicle in the
detection zone, the side BSW/RCTA indica-
tor light (1) illuminates. If the turn signal is
then activated, the system chimes (twice)
and the side BSW/RCTA indicator light
flashes. The side BSW/RCTA indicator light
continues to flash until the detected ve-
hicle leaves the detection zone.
The side BSW/RCTA indicator light illumi-
nates for a few seconds when the ignition
switch is placed in the ON position.
The brightness of the side BSW/RCTA indi-
cator light is adjusted automatically de-
pending on the brightness of the ambient
light.
If a vehicle comes into the detection zone
af ter the driver activates the turn signal,
then only the side BSW/RCTA indicator light
flashes and no chime sounds. For addi-
tional information, refer to “BSW driving
situations” in this section.The BSW system automatically turns on
every time the engine is started, as long as
it is activated using the settings menu on
the vehicle information display.

NOTE:∙ When enabling/disabling the system,
the system will retain current set-
tings even if the engine is restarted.
∙ The RCTA system is integrated into
the BSW system. There is not a sepa-
rate selection in the vehicle informa-
tion display for the RCTA system.
When the BSW is disabled, the RCTA
system is also disabled.
∙ When the BSW system is turned on,
the BSW/RCTA indicator (white) in the
vehicle information display illumi-
nates.
BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSW system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The BSW system cannot detect all ve- hicles under all conditions.
∙ The radar sensors may not be able to detect and activate BSW when certain
objects are present such as: – Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low
height vehicles, or high ground
clearance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detec- tion zone when you accelerate
from a stop.
– A vehicle merging into an adjacent lane at a speed approximately the
same as your vehicle.
– A vehicle approaching rapidly from behind.
– A vehicle which your vehicle over- takes rapidly.
– A vehicle that passes through the detection zone quickly.
– When overtaking several vehicles in a row, the vehicles af ter the first
vehicle may not be detected if they
are traveling close together. ∙ The radar sensors’ detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect ve-
hicles in an adjacent lane. When driv-
ing in a narrow lane, the radar sensors
may detect vehicles driving two lanes
away.
∙ The radar sensors are designed to ig- nore most stationary objects; how-
ever, objects such as guardrails, walls,
foliage and parked vehicles may oc-
casionally be detected. This is a nor-
mal operation condition.
∙ The following conditions may reduce the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on the vehicle
∙ Do not attach stickers (including transparent material), install accesso-
ries or apply additional paint near the
radar sensors. These conditions may
reduce the ability of the radar to de-
tect other vehicles.

Illustration 2:If the driver activates the
turn signal when another vehicle is in the
detection zone, then the system chimes
(twice) and the side indicator light flashes.
NOTE:
∙ The radar sensors may not detect ve-
hicles which are approaching rapidly
from behind. ∙
If the driver activates the turn signal
before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the
other vehicle is detected.
Overtaking another vehicle
Illustration 3: The side indicator light illu-
minates if you overtake a vehicle and that
vehicle stays in the detection zone for ap-
proximately 2 seconds.

Illustration 4:If the driver activates the
turn signal while another vehicle is in the
detection zone, then the system chimes
(twice) and the side indicator light flashes.
NOTE:
∙ When overtaking several vehicles in a
row, the vehicles af ter the first vehicle
may not be detected if they are trav-
eling close together.
∙ The radar sensors may not detect
slower moving vehicles if they are
passed quickly. ∙
If the driver activates the turn signal
before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the
other vehicle is detected.Entering from the side

NOTE:
∙ If the driver activates the turn signal
before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the
other vehicle is detected. ∙
The radar sensors may not detect a
vehicle which is traveling at about the
same speed as your vehicle when it
enters the detection zone.

SYSTEM TEMPORARILY
UNAVAILABLE
When radar blockage is detected, the sys-
tem will be deactivated automatically. The
“Side Radar Obstruction” warning message
will appear and the BSW/RCTA indicator
(white) will blink
Ain the vehicle informa-
tion display.
The system is not available until the condi-
tions no longer exist.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the radar sen-
sors.
NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.

Malfunction
If the BSW system malfunctions, it will turn
off automatically. The BSW/RCTA indicator
(orange) will appear in the vehicle informa-
tion display.
NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the mes-
sage continues to appear, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
SYSTEM MAINTENANCE
The two radar sensors1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the ra-
dar sensors clean.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the radar sensors.
Do not strike or damage the area around
the radar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the radar sensors is damaged due to a
collision.
