sensor NISSAN ALTIMA 2023 Owner's Manual

If the ambient image sensor is damaged
due to an accident, it is recommended that
you visit a NISSAN dealer.
Battery saver system
If the ignition switch is placed in the OFF
position while the headlight switch is in the
orposition, the headlights will
turn off af ter a period of time.
CAUTION
Even though the battery saver feature
automatically turns off the headlights
af ter a period of time, you should turn
the headlight switch to the OFF posi-
tion when the engine is not running to
avoid discharging the vehicle battery.
LED DAYTIME RUNNING LIGHTS
(DRL) SYSTEM (if so equipped)
The LED DRL automatically illuminate at
100% intensity when the engine is started
and the parking brake released. The LED
Daytime Running Lights (DRL) operate with
the headlight switch in any position. When
you turn the headlight switch to the
position for full illumination, the LED DRL
illuminate at a lower intensity. If the parking brake is applied before the
engine is started, the LED DRL do not illumi-
nate. The LED DRL illuminate when the
parking brake is released. The LED DRL will
remain on until the ignition switch is placed
in the OFF position.
At dusk, the headlights, interior controls
and switches will automatically illuminate if
the headlight switch is in the AUTO
position.
WARNING
When the LED DRL system is active, tail
lights on your vehicle are not on. It is
necessary at dusk to turn on your
headlights. Failure to do so could cause
an accident injuring yourself and
others.

•If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with underinflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light off. If you have
a flat tire, replace it with a spare tire
as soon as possible. (For additional
information, see “Flat tire” (P. 6-3) for
changing a flat tire.) •
When using a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, tire pressure will not be in-
dicated, the TPMS will not function
and the low tire pressure warning
light will flash for approximately 1
minute. The light will remain on af ter
1 minute. It is recommended that you
visit a NISSAN dealer for tire replace-
ment and/or system resetting.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CAUTION
Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception of
the signals from the tire pressure sen-
sors, and the TPMS will not function
properly. Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate.
Some examples are:
• Facilities or electric devices using similar
radio frequencies are near the vehicle.
• If a transmitter set to similar frequencies is being used in or near the vehicle.
• If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may
illuminate in the following cases:
• If the vehicle is equipped with a wheel and tire without TPMS.
• If the TPMS has been replaced and the ID has not been registered.
• If the wheel is not originally specified by NISSAN.

TPMS with Easy-Fill Tire Alert
When adding air to an under-inflated tire,
the TPMS with Easy-Fill Tire Alert provides
visual and audible signals outside the ve-
hicle to help you inflate the tires to the rec-
ommended COLD tire pressure.
Vehicle set-up
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place theshif t lever in the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation
1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When the pressure reaches the designated
pressure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds af ter
starting to inflate the tire, it indicates
that the Easy-Fill Tire Alert is not
operating.
• The TPMS will not activate the Easy-Fill Tire Alert under the following
conditions:– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire.
– There is a malfunction in the TPMS.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sen- sor is low.
• If the Easy-Fill Tire Alert does not oper- ate due to TPMS interference, move
the vehicle about 3 f t (1 m) backward
or forward and try again.
If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.

WARNING
Failure to follow the warnings and in-
structions for proper use of the BSW
system could result in serious injury or
death.
• The BSW system is not a replacement
for proper driving procedures and is
not designed to prevent contact with
vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the di-
rection your vehicle will move to en-
sure it is safe to change lanes. Never
rely solely on the BSW system.
The BSW system helps alert the driver of
other vehicles in adjacent lanes when
changing lanes. The BSW system uses radar sensors
O1
installed near the rear bumper to detect
other vehicles in an adjacent lane.
The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion zone shown as illustrated. This detec-
tion zone starts from the outside mirror of
your vehicle and extends approximately 10
f t (3.0 m) behind the rear bumper, and ap-
proximately 10 f t (3.0 m) sideways.

BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 mph (32 km/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),
the side BSW/RCTA indicator light flashes
and the BSW indicator illuminates (yellow)
in the vehicle information display. The side
BSW/RCTA indicator light continues to
flash until the detected vehicle 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.
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, see “BSW driving situa-
tions” (P. 5-52).
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.

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 cer-
tain 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 sen-
sors 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 occasionally be detected. This is
a normal 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 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 (for example, audio
system volume, open vehicle win-
dow) will interfere with the chime
sound, and it may not be heard.
