sensor NISSAN ALTIMA 2020 Owner´s Manual

∙ If the low tire pressure warning lightilluminates 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. Driv-
ing with underinflated tires may per-
manently damage the tires and in-
crease the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light off. If you have a flat
tire, replace it with a spare tire as soon
as possible. (For additional informa-
tion, refer to “Flat tire” in the “In case of
emergency ” section for changing a
flat tire.) ∙ When replacing 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 indi-
cated, 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 replacement and/or
system resetting.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
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 simi- lar radio frequencies are near the ve-
hicle.
∙ If a transmitter set to similar frequen- cies 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.

cept any interference, including interfer-
ence that may cause undesired opera-
tion of the device.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-up1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shif t lever in the P (Park) position.
3. Place the ignition switch in the ON po- sition. 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 pres-
sure, push the core of the valve stem on the tire briefly to release pressure.
When the pressure reaches the des-
ignated pressure, the horn beeps
once.
∙ If the hazard indicator does not flash within approximately 15 seconds af-
ter starting to inflate the tire, it indi-
cates that the Easy-Fill Tire Alert is
not operating.
∙ The TPMS will not activate the Easy- Fill Tire Alert under the following con-
ditions:
– 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.

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 replacementfor 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 direc-
tion your vehicle will move to ensure 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
1
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
approximately 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.
The brightness of the side BSW/RCTA indica-
tor light is adjusted automatically depending
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.

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
5-48Starting and driving

– Ice/frost/snow/dirt build-up onthe 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.
∙ Excessive noise (for example, audio system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.

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 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.
