2020 NISSAN ALTIMA sensor

Be sure you do not put anything on top
of the autolight sensor located in the top
side
1of the instrument panel. The au-
tolight sensor controls the autolight; if it
is covered, the autolight sensor reacts as
if it is dark out and the headlights will
illuminate. If this occurs while parked
with the engine off and the ignition
switch placed in the ON position, your
vehicle’s battery could become dis-
charged.

the lever forward. The high beam lights
come on and the
light illumi-
nates in the meter.
2Pull the lever back to select the low
beam.
3Pulling and releasing the lever flashes
the headlight high beams on and off.
High Beam Assist (if so equipped)
The High Beam Assist system will operate
when the vehicle is driven at speeds of ap-
proximately 25 mph (40 km/h) and above. If
an oncoming vehicle or leading vehicle ap-
pears in front of your vehicle when the
headlight high beam is on, the headlight
will be switched to the low beam automati-
cally.
WARNING
∙ The High Beam Assist system is a con- venience but it is not a substitute for
safe driving operation. The driver
should remain alert at all times, en-
sure safe driving practices and switch
the high beams and low beam manu-
ally when necessary.
∙ The high beam or low beam may not switch automatically under the fol-
lowing conditions. Switch the high
beam and low beam manually.
– During bad weather (rain, fog, snow, wind, etc.).
– When a light source similar to a headlight or tail light is in the vicin-
ity of the vehicle.

Instruments and controls2-47

When the vehicle speed lowers to less than
approximately 16 mph (25 km/h), the head-
light uses the low beam.
To turn off the High Beam Assist system,
turn the headlight switch to the
posi-
tion or select the low beam position by
placing the lever in the neutral position.
Ambient image sensor maintenance
The ambient image sensor
1for the High
Beam Assist system is located in front of
the inside mirror. To maintain the proper
operation of the high beam assist system
and prevent a system malfunction, be sure
to observe the following:
∙ Always keep the windshield clean.
∙ Do not attach a sticker (including trans- parent material) or install an accessory
near the ambient image sensor. ∙ Do not strike or damage the areas
around the ambient image sensor. Do
not touch the sensor lens that is lo-
cated on the ambient image sensor.
If the ambient image sensor is damaged
due to an accident, it is recommended that
you visit a NISSAN dealer.
Battery saver system (if so
equipped)
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 position
when the engine is not running to avoid
discharging the vehicle battery.

∙ 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.

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.
