2021 NISSAN SENTRA spare tire

Low tire pressure warning
light
Your vehicle is equipped with a Tire Pres-
sure Monitoring System (TPMS) that moni-
tors the tire pressure of all tires except the
spare.
The low tire pressure warning light warns
of low tire pressure or indicates that the
TPMS is not functioning properly.
Af ter the ignition switch is placed in the ON
position, this light illuminates for about 1
second and turns off.
Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illumi-
nate. The “Tire Pressure Low – Add Air”
appears in the vehicle information dis-
play.
When the low tire pressure warning light
illuminates, you should stop and adjust
the tire pressure of all four tires to the
recommended COLD tire pressure shown
on the Tire and Loading Information la-
bel located in the driver’s door opening.
The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. Af ter the tire is in-
flated to the recommended pressure,the vehicle must be driven at speeds
above 16 mph (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
The “Tire Pressure Low - Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains illumi-
nated.
For additional information, refer to “Vehicle
information display” in this section, “Tire
Pressure Monitoring System (TPMS)” in the
“Starting and driving” and “In case of emer-
gency” sections of this manual.TPMS malfunction
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The
light will remain on af ter 1 minute. Have the
system checked. It is recommended that
you visit a NISSAN dealer for this service.
The “Tire Pressure Low— Add Air” warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
For additional information, refer to “Tire
Pressure Monitoring System (TPMS)” in the
“Starting and driving” section and “Tire
pressure” in the “Do-it-yourself ” section of
this manual.

•If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle
speed, pull off the road to a safe loca-
tion 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 acci-
dent and could result in serious per-
sonal injury or death. Check the tire
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure show on the Tire
and Loading Information label lo-
cated in the driver’s door opening to
turn the low tire pressure warning
light off. If the light still illuminates
while driving af ter adjusting the tire
pressure, a tire may be flat or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a spare
tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit a NISSAN
dealer for this service. •
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 these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
• If the vehicle is being driven at
speeds of less than 16 mph (25 km/h),
the TPMS may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.

•The request switch is operational
only when the Intelligent Key has
been detected by the Intelligent Key
system.
Lockout protection
To prevent the Intelligent Key from being
accidentally locked in the vehicle, lockout
protection is equipped with the Intelligent
Key.
When the driver’s side door is open, the
doors are locked and then the Intelligent
Key is put inside the vehicle and all the
doors are closed; the lock will automati-
cally unlock and the door buzzer sounds.
NOTE:
The doors may not lock when the Intelli-
gent Key is in the same hand that is op-
erating the request switch (if so
equipped) to lock the door. Put the Intel-
ligent Key in a purse, pocket or your
other hand.
CAUTION
The lockout protection may not func-
tion under the following conditions:
• When the Intelligent Key is placed on
top of the instrument panel.
• When the Intelligent Key is placed on
top of the rear parcel shelf.
• When the Intelligent Key is placed in-
side the glove box or a storage bin.
• When the Intelligent Key is placed in-
side the door pockets.
• When the Intelligent Key is placed on
or under the spare tire area.
• When the Intelligent Key is placed in-
side or near metallic materials.

3-12Pre-driving checks and adjustments

•Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION
• Do not use leaded gasoline. Deposits
from leaded gasoline will seriously
reduce the three-way catalyst's abil-
ity to help reduce exhaust pollutants.
• Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended that
you visit a NISSAN dealer for this
service.
• Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
• Do not race the engine while warm-
ing it up. •
Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions
may occur for a variety of reasons, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

Additional information:
• When replacing a wheel without theTPMS such as the spare tire, the TPMS
does not monitor the tire pressure of the
spare tire.
• The TPMS will activate only when the ve- hicle is driven at speeds above 16 mph (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example,
a flat tire while driving).
• The low tire pressure warning light does not automatically turn off when the tire
pressure of all your tires is adjusted. Af ter
the tires are inflated to the recom-
mended pressure, the vehicle must be
driven at speeds above 16 mph (25 km/h)
to activate the TPMS and turn off the low
tire pressure warning light. Use a tire
pressure gauge to check the tire pres-
sure. • The “CHECK TIRE PRES” (TypeA-ifso
equipped) or the “Tire Pressure Low - Add
Air”(TypeB-ifsoequipped) warning mes-
sage is displayed in the odometer when
the low tire pressure warning light is illu-
minated and low tire pressure is de-
tected. The “CHECK TIRE PRES” (Typ eA-if
so equipped) or the “Tire Pressure Low -
AddAir”(TypeB-ifsoequipped) warning
message turns off when the low tire pres-
sure warning light turns off. The low tire
pressure warning light remains illumi-
nated until the tires are inflated to the
recommended COLD tire pressure. The
“CHECK TIRE PRES” (TypeA-ifso
equipped) or the “Tire Pressure Low - Add
Air”(TypeB-ifsoequipped) warning mes-
sage is displayed each time the ignition
switch is placed in the ON position as
long as the low tire pressure warning light
remains illuminated.
• The “CHECK TIRE PRES” (TypeA-ifso equipped) or the “Tire Pressure Low - Add
Air”(TypeB-ifsoequipped) warning is not
displayed if the low tire pressure warning
light illuminates to indicate a TPMS mal-
function. • Tire pressure rises and falls depending on
the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure af ter driving be-
cause the tire pressure rises af ter driving.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates, check the tire
pressure for all four tires.
• The Tire and Loading Information label is located in the driver's door opening.
For additional information, refer to “Check
tire pressure warning message” or “Low tire
pressure warning light” in the “Instruments
and controls” section and “Tire Pressure
Monitoring System (TPMS)” in the “In case of
emergency” section of this manual.

•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.

The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
