TPMS NISSAN SENTRA 2021 User Guide

•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 under-inflated 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 on changing a flat tire,
refer to “Flat tire” in the “In case of
emergency ” section of this manual.) •
When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, 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. Have your tires replaced
and/or TPMS reset as soon as pos-
sible. It is recommended that you
visit a NISSAN dealer for this service.
• 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 the
shif t lever in the P (Park) position (if so
equipped).
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 oper-
ating. • The TPMS will not activate the Easy-Fill
Tire Alert under the following condi-
tions:
– If there is interference from an ex- ternal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire.
– There is a malfunction in the TPMS system.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire’s pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor 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.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit, and the “CHECK TIRE PRES” (ve-
hicles without a vehicle information dis-
play) also appears in the trip computer or
the “Tire Pressure Low - Add Air” (vehicles
with a vehicle information display) appears
in the vehicle information display, one or
more of your tires is significantly under-
inflated. If the vehicle is being driven with
low tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light. This system will activate only
when the vehicle is driven at speeds above
16 mph (25 km/h). For additional informa-
tion, refer to “Warning lights, indicator lights
and audible reminders” in the “Instruments
and controls” section, and “Tire Pressure
Monitoring System (TPMS)” in the “Starting
and driving” sections of this manual.

If you have a flat tire, refer to “Flat tire” in
the “In case of emergency ” section of
this manual.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)

•If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad/shoe wear. For additional infor-
mation on wheel-off set dimensions,
refer to “Wheels and tires” in the
“Technical and consumer informa-
tion” section of this manual.
• When replacing a wheel without the
TPMS such as the spare tire, 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. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS. •
The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
• When replacing the TPMS sensor, the
ID registration may be required. Con-
tact a NISSAN dealer for ID
registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
• Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
• For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Care of wheels
• Wash the wheels when washing the ve- hicle to maintain their appearance.
• Clean the inner side of the wheels when the wheel is changed or the underside of
the vehicle is washed.
• Do not use abrasive cleaners when washing the wheels.
• Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
• NISSAN recommends waxing the road wheels to protect against road salt in ar-
eas where it is used during winter.

Spare tire (TEMPORARY USE ONLY
spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be
damaged or involved in an accident:
CAUTION
• Do not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause
damage to the vehicle.
• Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not
drive the vehicle through an auto-
matic car wash since it may get
caught.

secondary latch keeps the hood from
opening when the primary latch is re-
leased.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires should be rotated ev-
ery 7,500 miles (12,000 km).
Tires*: Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the
TPMS transmitter grommet seal, valve core
and cap when the tires are replaced due to
wear or age. Wheel alignment and balance:
If the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may
be a need for wheel alignment. If the steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield: Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind-
shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to
http://collision.nissanusa.com.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Continuously Variable Transmission
(CVT) P (Park) position mechanism (if so
equipped): On a fairly steep hill check that
the vehicle is held securely with the shif t
lever in the P (Park) position without apply-
ing any brakes.
