2023 NISSAN ALTIMA sensor

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.

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.

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.

SYSTEM TEMPORARILY
UNAVAILABLE
When radar blockage is detected, the sys-
tem will be deactivated automatically. The
“Unavailable: Side Radar Obstruction”
warning message will appear in the vehicle
information display.
The systems are not available until the
conditions no longer exist.
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 conditions such as ice, snow, frost or dirt
obstructing the radar sensors.
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.

If the radar sensorO1detects a slower
moving vehicle ahead, the system will re-
duce the vehicle speed so that your vehicle
follows the vehicle in front at the selected
distance.
The system automatically controls the
throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power)
if necessary.
The detection range of the sensor is ap-
proximately 650 f t (200 m) ahead.

CONTROL MODE OPERATION
LSD4551
5-74Starting and driving

NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects objects on the
side of the vehicle or on the side of the
road. This may cause the ICC system to
decelerate or accelerate the vehicle. The
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
entering or exiting a curve. In these
cases you will have to manually control
the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed:
• When the vehicle ahead is not detectedand your vehicle is traveling below the
speed of 15 mph (25 km/h)
• When the system judges the vehicle is at a standstill • When the shif t lever is not in the D (Drive)
position, Manual mode or L (Low) range.
• When the parking brake system is applied
• When the VDC system is turned off
• When VDC operates
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
• When a wheel slips
• When the radar signal is temporarily interrupted
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE LIMITATIONS
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
• The ICC system is primarily intended
for use on straight, dry, open roads
with light traffic. It is not advisable to
use the ICC system in city traffic or
congested areas. •
The ICC system will not adapt auto-
matically to road conditions. This
system should be used in evenly
flowing traffic. Do not use the system
on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
• As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absentminded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the
brake pedal, depending on the dis-
tance to the vehicle ahead and the
surrounding circumstances in order
to maintain a safe distance between
vehicles.
• If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
