2023 NISSAN ALTIMA Owners Manual

SYSTEM MAINTENANCE
The two radar sensorsO1for 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.
Radio frequency statement
NOTICE:
This device complies with Part 15 of the FCC
Rules.
Operation is subject to the following two
conditions:
this device may not cause harmful interfer-
ence, and
this device must accept any interference
received, including interference that may
cause undesired operation.
Changes or modifications made to this
equipment not expressly approved by
(manufacturer name) may void the FCC
authorization to operate this equipment.
NOTE:
This equipment has been tested and
found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to
provide reasonable protection against
harmful interference in a residential in-
stallation. This equipment generates, uses
and can radiate radio frequency energy
and, if not installed and used in accor-
dance with the instructions, may cause
harmful interference to radio communi-
cations. However, there is no guarantee
that interference will not occur in a par-
ticular installation. If this equipment does
cause harmful interference to radio or
television reception, which can be deter-
mined by turning the equipment off and
on, the user is encouraged to try to correct
the interference by one or more of the fol-
lowing measures:
Reorient or relocate the receiving antenna.
Increase the separation between the
equipment and receiver.
Connect the equipment into an outlet on
a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced
radio/TV technician for help.

WARNING
Failure to follow the warnings and in-
structions for proper use of the RCTA
could result in serious injury or death.
• The RCTA system is not a replace-
ment for proper driving procedures
and is not designed to prevent con-
tact with vehicles or objects. When
backing out of a parking space, al-
ways use the side and rear mirrors
and turn and look in the direction
your vehicle will move. Never rely
solely on the RCTA system.
The RCTA system will assist you when
backing out from a parking space. When
the vehicle is in reverse, the system is de-
signed to detect other vehicles approach-
ing from the right or lef t of the vehicle. If the
system detects cross traffic, it will alert you.

(if so equipped)
5-58Starting and driving

1. Side BSW/RCTA Indicator Light
The RCTA system can help alert the driver
of an approaching vehicle when the driver
is backing out of a parking space.
When the shif t position is in R (Reverse) and
the vehicle speed is less than approxi-
mately 5 mph (8 km/h), the RCTA system is
operational.
If the radar detects an approaching vehicle
from either side, the system chimes (once)
and the side BSW/RCTA indicator light
flashes on the side the vehicle is approach-
ing from.

For vehicles with the 5 inch (13 cm) display
Starting and driving5-59

The RCTA system uses radar sensorsO1
installed on both sides near the rear bum-
per to detect an approaching vehicle.
The radar sensors
O1can detect an ap-
proaching vehicle from up to approxi-
mately 66 f t. (20 m) away.

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.
LSD3195
Starting and driving5-63

–IllustrationOE: When the angle
formed by your vehicle and ap-
proaching vehicle is small.
• 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 acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar to
detect other vehicles.
• Excessive noise (e.g., audio system
volume, open vehicle window) will in-
terfere with the chime sound, and it
may not be heard.
NOTE:
In the case of several vehicles approach-
ing in a row (Illustration 1) or in the oppo-
site direction (Illustration 2), a chime may
not be sounded by the RCTA system af-
ter the first vehicle passes the sensors.
